Why doesn't oil flow to the chainsaw chain?

How to choose a chain

Studying their typology will help you choose a chain. Important criteria of distinction are:

Tooth pitch. This parameter is measured in inches. The most common sizes are 0.325, 0.375 and 0.404. Each of them is selected depending on the assigned tasks. The smaller the specified parameter, the lower the productivity will be, which means you won’t need to put in a lot of effort. Therefore, it is necessary to purchase a chain whose power would correspond to a chainsaw.
The thickness of the tail and drive link, which means the product can be selected for different tires. The 1.1 mm thick tail is found only on small chains for household saws. The most popular size is 1.3 mm. This model can be present even on semi-professional devices.
Depth of the cut and height of the profile. The performance of the device depends on this parameter. It is always possible to increase the value if you cut off the stops near each cutter. There are two options to choose from: 0.025” (0.635 mm) and 0.03” (0.762 mm). The presence of a high-profile chain makes the chainsaw aggressive and shaving. A product with a small tail pitch will help maintain a balance between high productivity and low vibration.
Chain length, bars and number of teeth. The choice of this parameter directly depends on the power characteristics of the chainsaw. Moreover, the best saws are not always characterized by an increased number of teeth and tire size.
Types of cutting links. Types of chains according to this characteristic: chisel and chipper. The first option is the most optimal due to the straight working surface, which allows you to cut evenly into the wood. It is difficult to sharpen such links, and if there are even very small deviations from the upper corners, the performance of the chain will be reduced. Chipper ones have worse cutting characteristics, but are more resistant to any kind of contamination and are easier to sharpen.
Sequence of links. A popular model is one with one cutting link and two tails. But non-standard options are also possible: with a semi-allowance - only one connecting link is inserted between every second pair of working teeth; with an allowance - the link is installed between all adjacent teeth. This allows you to reduce the cost. But at the same time, aggressiveness and performance decrease, and wear increases, including chainsaws.
Method of cutting material. Products with longitudinal and cross cuts allow you to guide the tire along and across the fibers, depending on the need. They differ in the angle of sharpening of the cutting links.

How to install a chain

A long service life of the device is possible not only if the components for it are carefully selected, but the installation of the chain on the chainsaw must also be correct. In addition, sooner or later the chain may need to be replaced. In this case, it is necessary to think about safety, in particular, carry out work using special protective gloves. To “dress” the saw, you need to perform actions in the following sequence:

Prepare the surface for work. You can place the chain correctly on a table or other convenient and flat surface. Additionally, the surface can be covered with a rug.
The wing nut on the housing must be unscrewed, and then the sprocket cover must be removed.
The latter must be turned to the right all the way. After this, gradually put the chain on top of the bar, while it is better to start work from its top. At each stage, it is recommended to ensure that the chain is directed correctly.
Turn the chain so that the bar is on top of it. At this stage, the cutter located on the top of the tire should be facing forward, not to the side. This indicates that the direction of movement is correct and the location is accurate.
Place the tire on the sprocket.
After this, put the chain sprocket cover on the engine block, turn the wing nut until it stops, but do not completely tighten the sprocket cover.
Unscrew the clamping screw by turning it towards the top of the bar, while the chain links should fall into the corresponding recesses.
Tighten the wing nut until secure.
Check the part for sagging and tightness, and if necessary, tighten it further or loosen it.

Chainsaw setup work

Work on adjusting a chainsaw is divided into two groups:

setting up individual nodes;
preventive tool maintenance.

Carburetor settings

The carburetor is one of the components that ensures stable operation of the chainsaw. The speed at which the speed increases, the power output, and the uniformity of sawing depend on it.

Adjusting the unit comes down to setting the minimum and maximum speed of the internal combustion engine, as well as setting the idle speed. This can be done independently or with the help of a professional technician.

With a properly adjusted, clean carburetor, the engine provides:

immobility of the chain in idle mode;
smooth and fast increase in chainsaw engine speed;
When operating, the gasoline unit sounds similar to a 4-stroke engine.

Chain tension

Chain tension adjustment is carried out:

when installing a chain on a chainsaw after sharpening;
when the tension weakens during operation of the chainsaw;
when replacing a worn or faulty chain with a new one.

The chain tension is carried out with a special screw. Most often, for convenience, it is placed on the side surface. The tension force is adjusted experimentally. The normal position of the chain is determined by the tire, and the lower part of the chain cannot have any play, since it should not sag.

The degree of tension is determined manually - with a hand wearing a protective glove, the chain is scrolled. With the chain in the normal position in the tire, the movement of the cutting tool should be free, without much effort.

Note: when adjusting the chain tension, the brake must be in a free state - unlocked.

Tip: when operating the saw in winter conditions, tensioning must be carried out on a heated saw - as the temperature rises, the metal elements expand and the chain may sag. At the end of the work, the tension should be loosened - during cooling, excessive stress may arise from contraction of the metal during the cooling process.

Chain lubrication mechanism

For stable operation, the chain must be lubricated with oil. This role is performed by a special unit - the lubrication mechanism. During operation, interruptions in its operation may occur:

there is a lack of oil in the tank, as a result of which a small amount of lubricating fluid will flow to the chain - it is necessary to replenish the oil level;
clogging of the outlet channels - the filter needs to be cleaned and replaced;
The small diameter of the outlet hole is adjusted with a special screw.

During normal operation of the chain lubrication system, traces of oil can be seen if you bring the running saw to a light, uncontaminated surface, for example, to a fresh cut of wood (stump).

The amount of oil supplied to the chain depends on the operating conditions. With dense, viscous or damp wood, the oil consumption should be greater. Dry material will require less lubricant.

Why does the chain fly off and break?

If the chain falls off the chainsaw or it breaks, this means that there is some kind of problem with the device; under normal conditions it should not do this. There are three reasons why a chain falls off:

Tire problems. They lead to loosening of the tension, which can lead to the chain breaking. Most often, this problem occurs in the groove between the outer plate on the chain set housing and the inner plate on the motor housing. The casing with the tire is secured with a bolt, which can become loose during operation of the chainsaw, as a result of which the tire begins to move or vibrate. To solve this problem, you need to find and lower the chain brake, for which you need to turn the tension screw, which is located next to the tire, until it is fully tensioned.
The chain has stretched. Sagging may indicate a malfunction of the chainsaw mechanism. During operation, the metal is deformed, which means it can become 0.5-1 cm longer. In this case, it is recommended to replace or shorten the chain.
The drive sprocket is poorly secured. To secure it, you need to remove the engine protective cover and spark plugs, and then pull out the air filter. The spark plug itself also needs to be unscrewed, after which a special stopper is installed in its place to secure the piston. Turn the fastening disk clockwise until the piston stops in the uppermost position. A thick rope folded several times can act as a stopper. After fixing the piston, clamp the drive sprocket. Reassemble the chainsaw, installing all parts in the reverse order.

Most problems can be solved by repair. Only in exceptional cases will it be necessary to change it.

Poor oil supply to the chainsaw chain

Why is the oil not flowing

on a chainsaw chain?

If during operation the chainsaw chain does not receive oil, you need to find the cause of the problem. In fact, there may be many reasons influencing this common rumor process. You should disassemble the chainsaw and identify the main problem. The probable prerequisites for this process will be described below.

There are several reasons for the lack of oil supply to the chain while the chainsaw is running, and you also need to disassemble the chainsaw to identify them.

Possible reasons for fuel failure

Oil

the circuit may not
be supplied only if there are two breakdowns. These include:

problems with air leaks;
failure of the oil pump
.

Basic parameters of a chainsaw chain.

The main cause of failure is air leaks. This can happen due to depressurization of the oil hose while using the chainsaw. In this case, it is necessary to remove the hose from the hole. This must be done in the place where it is connected to the crankcase. Then the hose is seated on the sealant and installed in its usual position. If this doesn't help, there's likely been a loss of elasticity. For further operation of the chainsaw, it is advisable to replace the hose.

READ Oil Leaking From Champion Chainsaw

The second reason is a breakdown of the oil pump

.
In common parlance this part is called a worm. When the drive fails, oil will stop flowing to the chain. The oil pump drive is a round plastic ring with grooves inside. Constant use of a chainsaw leads to wear of the internal parts, resulting in the metal hook located inside the drive being chipped. After this breakdown, oil stops flowing to the chain.
You can troubleshoot problems yourself or under the guidance of specialists.

Features of the lubrication system and choice of oil

Fuel tanks are selected exactly according to volume. At maximum output, it is permissible to select components with a small amount of oil.

Reasons for stopping the oil supply in a chainsaw

Brief overview of why oil

the
chainsaw
has stopped supplying the tire from the tank. Support our channel in any way you can.

Chainsaw fuel system: 1 – fuel filter, 2 – carburetor, 3 – manual pre-priming pump.

If the carburetor is adjusted correctly, fuel will be consumed in the permissible amount. Otherwise, it will end too quickly.

A slow decrease in fuel while the saw is in use is normal. If it is missing, the chain is not lubricated correctly, so working with the chainsaw must be smooth. It is necessary not only to be able to fix breakdowns, but also to identify them yourself.

READ Screwdriver for Chainsaw Adjustment

You can change the fuel supply manually. The correct operation of the lubrication system is determined by holding the tire up. If oil splashes appear, then everything is set up correctly.

It is advisable to make cuts with a significant amount of lubricant. If you have to work with soft wood, a small amount of fuel is supplied.

Chain

should always be well lubricated. This will avoid smoke and further failure of the entire chainsaw. If oil leaks or does not flow at all, it is necessary to identify the cause of the breakdown. It is not recommended to operate the tool until repaired.

When choosing fuel, you need to do it correctly. The desire to save money leads to the fact that the chain quickly fails. To avoid unpleasant consequences, it is not advisable to choose oil produced in China. Preference should be given to original companies. In their price category they are much higher, but their quality is also better.

Troubleshooting Circuit Problems

During operation of the chainsaw, it is necessary to constantly monitor the lubrication of the chain. After all, it is this part that works in the most difficult conditions. The chain is constantly overheated and dust and abrasive particles become clogged with it. All this negatively affects its service life. A special lubricant will correct the situation. It is supplied to the chain from the tank, thereby ensuring unhindered operation.

READ How to Correctly Check the Spark on a Chainsaw Partner

If lubrication does not occur during operation, there is a high risk of overheating. When there is no oil flow, the chain begins to stretch. At the same time, there is still a possibility of it jamming or spontaneously jumping off, as a result of which a person can receive serious injury.

The channels through which fuel is supplied can become clogged with small particles, so it is advisable to clean them periodically. It is also important to monitor the oil level in the tank. Debris in the channel is a common cause of chain brake failure. This may have a negative impact on your work.

Regular cleaning of the channels and general maintenance of the chainsaw will allow the tool to function for a long time.

But what to do if all the recommendations are followed, and the oil

it still flows. It is necessary to ensure that the chainsaw is operating correctly. It is likely that it was assembled incorrectly. If the breakdown has not been identified, it is recommended to take it to a workshop. In some cases, it is necessary to replace the pump, but this should be done if the saw is new. Old tools leak due to worn out reservoir.

How to shorten a chain with your own hands

You can repair a chainsaw chain with your own hands, provided you have a special tool (most often included with the saw). Most often it is necessary to shorten it, especially if it has stretched. This is difficult to do, but possible. To repair it by shortening it, you need to prepare the following tools:

Some work can be done with a welding machine if you have doubts about your own abilities.

To shorten the chain on a chainsaw, you need to rivet it. Since it is made of durable steel, the process can be complex. It is connected on the inside of the rivet. The reduction is performed in the following sequence:

Secure the part in a vice.
Use a file or needle file to grind off the protruding part.
Knock out the rivets using a punch.
Do similar work in another place. This allows you to rivet it.
Remove links.
Connect with old rivets, while pressing them on the sides. The rivet can be welded to the side parts of the link, after which all excess can be filed off.

What oil to use to lubricate the chain

This part requires constant lubrication, for which you can fill in special chainsaw oil, and it must be of high quality. It is recommended to choose oil for lubricating chainsaw chains from the manufacturer of the saw itself. Its consumption is small, so you should not save on your purchase. But there is no need to pour liquid on the chain itself. There are entire lubrication systems that help it flow to the tire uninterruptedly.

There are other criteria for choosing a saw lubricant:

resistance to freezing, because sometimes you have to use the saw in winter, including lubricating it with oil, which means that at subzero temperatures it should not freeze;
optimal viscosity of chain oil;
the oil used should not leave residue on candles and other spare parts;
no impurities.

The chain oil needs to be replaced if the part heats up and various breakdowns occur.

Chain lubrication diagram

The chainsaw chain lubrication system consists of the following elements:

oil tank, which is located in the engine crankcase;
filter in the tank;
oil line, that is, a small diameter hose;
oil pump.

Chainsaws are equipped with an automatic lubrication system. This means that oil flows to the chain only if it is in contact with the wood. The system operation scheme is as follows. The gear, which is located on the main shaft, drives the oil pump shaft. This creates pressure in the oil line, which forces the oil to move towards the tire.

The oil channel ends at the point where the device tire comes into contact with the chainsaw crankcase. The tension of the chainsaw chain for oil supply does not matter. It still lubricates itself.

No oil getting to the chain

You can tell that oil is not getting to the chain by the following signs:

dryness of the part and lack of shine;
its rapid stretching;
heat;
no reduction of oil from the tank;
reduction in cutting efficiency.

To check whether or not there is oil supply, you need to point the end of the tire to the side and increase the speed as much as possible, while the end of the tire should be located at a distance of 10 cm from the tree.

If oil stains appear on the surface of the wood, then there is no problem with the oil supply. Feed may need to be adjusted.

The reasons for the lack of oil supply may be:

Missing thread on the oil pump shaft. In this case, it will need to be replaced.
Broken oil hose.
The presence of a defective thread on the pump drive gear.
Lack of main shaft corkscrew. The problem can be solved by installing a nail of a suitable diameter and the required length.
Blockage. You can clean the line by blowing it with compressed air or using a thin wire. If the blockage is in the filter or in the pump itself, then it is better to replace these parts.

How to Adjust the Oil Supply to a Chainsaw Chain

Chain lubrication system

One of the important chainsaw systems, without which this is impossible, is the forced lubrication chainsaw system. It is no secret that while the saw is running, the chains rub the chainsaw, which causes it to heat up and cause premature wear. To reduce friction, the chain mechanism must be constantly lubricated.

Chain lubrication system

To supply chain saw oil to the tool, a special pump is used, which, depending on the engine speed, is dosed and provides lubrication on the saw bar.

The system uses oil to lubricate the chain, which has increased adhesive properties, it is necessary to distribute the oil evenly around the entire perimeter of the tire and hold it even at high speeds. Let's take a closer look at the oil supply system implemented in modern chainsaws.

Lubrication system design

Depending on the brand of chainsaw, the parts of the lubrication system may differ slightly in design, but their total number and connection diagram remain unchanged.

The main components of the lubrication system are:

The oil reservoir is usually located in the engine crankcase.
The filter element is installed in the tank.
The oil pipeline is a small diameter hose made of oil rubber.
The heart of the system is the oil pump.
Worm gear transmission gear from motor to pump.
The chain saw can also be considered an element of the lubrication system, since it has special holes for supplying oil; by the way, the chain itself is involved in transporting oil and, accordingly, also has some elements specifically designed for lubrication.

READ Select a Chainsaw Chain According to the Tire

Operating principle

The main unit of the system is the pump. The principle of its operation is as follows. When the engine speed increases, a gear mounted on the main shaft drives the pump shaft through the worm gear. In turn, the rotation of the shaft creates a certain pressure in the oil line, which forces the oil to move along it towards the tire.

The end of the oil channel is located at the point of contact of the tire with the tool body, where there is a longitudinal groove on which, when the tire is installed, the oil channel enters it.

Threading is necessary to ensure that oil flows into the bar regardless of the chain saw's chain tension. Simply put, in any position that the tire has during operation, oil will fall through the hole onto it.

Next, the lubrication process involves a chain, on the links of which, depending on the chain model, there is either a groove or a hole through which the oil is accelerated throughout the tire. As the engine speed increases, the oil flow rate also increases.

How to regulate the oil supply on a chainsaw

maybe someone will find my first channel useful: .

How to adjust the oil supply to the chain in a regular chainsaw. Proper lubrication of a chainsaw chain

You can order bulletproof VPS for your adult projects using this link.

Some chainsaw models are equipped with pumps that additionally have power adjustment, and if necessary, the amount of oil supplied by the lubrication system can be increased or decreased.

This function is very convenient because it allows you to save money and not waste extra oil.

Malfunctions of the lubrication system and how to eliminate them

The main malfunctions of the oil supply system of a chainsaw can be divided into two main types: these are common problems found in all chainsaws and individual ones, which can vary depending on the type of pump and worm gear installed on a particular model. We will begin to understand the problems in order.

Do not lubricate the chain saw if the chain saw chains are not lubricated. This has a negative impact on the bar and chain and can also lead to significant repair costs.

READ How to Make a Chainsaw in The Forest

Signs of a malfunction of the lubrication system, checking its performance

The chainsaw chain is dry and has a pale tint without shine.
The chain extends relatively quickly.
The tire is very hot and even the paint may be partially melted.
The oil from the tank hardly decreases.
Cutting efficiency on a sharp chain has decreased

All these signs indicate that the lubrication process is not normal. To check the oil supply to the lubrication system, you need to remove the side chain of the chainsaw and start it. Then you need to increase your speed a little while watching where the oil line ends. If oil is coming in, there is likely not enough oil to provide proper lubrication and you will need to clean or replace the filter and, if possible, adjust the flow. If there is no receipt, the problem is more serious and requires further diagnosis.

There is a way to check the oil supply without removing the tire. To do this, you need to point the end of the tire to the side, such as the freshly cut shims on the side of the cut, and maximize speed while trying to keep the end of the tire no more than 10cm from the push. If oil stains begin to appear on its surface, oil is supplied.

Fixing problems

Once it has been determined that no oil is being supplied, further diagnosis is only possible if the oil system has been completely removed. Of course, in some situations, replacing the filter helps, but this is very rare.

Access to the oil pump of some saw models is possible only after complete disassembly; therefore, without the skills to repair gasoline tools, it is better to entrust the repair to professionals.

Most common failures

Broken oil hose. Sometimes this can be detected by visual inspection. The problem was resolved by replacing the faulty part.
Missing threads on the oil pump shaft will help replace it.
Incorrect threads on the pump drive gear are similarly resolved by installing a new part.
Lack of main shaft corkscrew (relevant for some instrument models, for example, Homelite). You can fix this by installing your own corkscrew to fit the diameter of the studs, cutting it to the required length.
Litter on the highway. Can be removed by blowing with compressed air or mechanically using a wire of suitable diameter.
Filter element clogged.
The Stil MS 180 tool, whose pump does not fold, often gets clogged. You can try flushing with pure gasoline if that doesn't help replace it.
The Chinese chainsaw (gypsy) very often cuts furrows on the main gear, through which the power from the sprocket is transmitted.

Individual malfunction of the Stihl MS 180 lubrication system

Due to the fact that the Stihl MS 180 is one of the most popular chainsaw models, I want to dwell in more detail on one inherent malfunction and describe a method for eliminating it without replacing parts.

It is quite common to see an oil line at the location where the oil pipe coming from the reservoir is installed in the saw body on the MS 180 stainless steel chainsaw. The malfunction may be indicated by characteristic lubricant contours on the bottom of the tool.

To solve the problem, remove the chain saw handle, remove the hose from the mounting hole, clean and degrease. After all these manipulations, apply sealant to the hose and install it into the chain saw body.

For more information on troubleshooting and fully diagnosing a chainsaw's lubrication system, you can learn by watching a video that records the process of disassembling and repairing the lubrication system step by step.

Conclusion

Modern chainsaws provide a reliable supply of chain lubricant in the event of failures, during operation of which there is no need to operate the chain to avoid further failures. Troubleshoot your lubrication system by contacting a service center or an experienced repair technician who can guarantee the quality of the final result.

Train tips

It’s not enough to know how to solve problems with a broken or broken chain, because there is always the opportunity to prevent this. Proper care of your saw will help extend the life of the device and its parts. Therefore, it is recommended to follow the advice of experts:

Clean the air filter regularly and lubricate it with oil. The filter needs to be changed periodically.
Each time before starting work, you need to check that all nuts and bolts are securely tightened. Then there will be no failures in the device during operation.
Both the bearings and the sprocket need to be lubricated.
Clean burnt candles regularly.
Lubricate, sharpen and tension the chain in a timely manner.

A high-quality chainsaw, provided proper care and timely repairs, can last longer than the warranty period.

When the saw chain of a chainsaw moves in the groove of the bar due to friction, a large amount of heat is released. If oil does not flow to the chainsaw chain, it is necessary to stop work and take all measures to eliminate the malfunction of the lubrication system. The combination of heavy loads and overheating of the headset is accompanied by its accelerated wear and early failure.

Without exception, all chainsaws and their electric analogues are equipped with systems of the same operating principle, through which the lubrication of the bar, saw chain and its drive parts is carried out.
The standard composition of this device includes a reservoir from which chain oil is supplied to the inlet of a pump with a fixed or adjustable capacity.
Next, the working fluid in a dosed amount enters the groove of the bar, in which it is evenly distributed by the shanks of the saw chain over the entire headset and the working surface of the drive sprocket crown.

Which oil to choose for a Shtil chainsaw: good advice

Of course, every owner of a chainsaw knows how important good and high-quality oil is for its specific lubrication. And, for sure, there is no need to say that this is the typical “life force” of this device for producing real and effective work. Today there is an unlimited number of oils and, as they say, there is plenty to choose from.

But, unfortunately, not every owner of this type of electrical equipment knows what oil to use for his steel friend so that the operation of the chainsaw is not only easy, but also productive. Therefore, in this article we will look at the issue regarding the correct choice of oil for chainsaws from the manufacturer Shtil. Also, what should it be in order to assist the chainsaw during its specific activity, and not harm. So let's get started.

Let's talk about the device for supplying oil directly to the chain

First, I would like to emphasize that all chainsaws from the manufacturer Shtil are quite small in size, but, nevertheless, they are very massive. It is these features that attract future buyers of this type of equipment to the models of this company. Moreover, you can easily create various kinds of manipulations with this device regarding work with wood (see how to cut down a tree).

Device for supplying oil to the chain In addition, Stihl chainsaws have a high level of cutting ability . Moreover, this equipment is equipped with the latest additional accessories, which contribute to the convenience and ease of operation. But actually, let's talk directly about the device itself, which the manufacturer equipped its chainsaws with. So, the direct chain lubrication system of the Stihl chainsaw consists of:

Guide tires;
Saw chains;
Oil pump.

It is worth noting that the direct oil supply through the pump has special adjustment . Another important fact is that the chain is lubricated throughout the operation of the chainsaw. If no oil flows to the chainsaw chain during operation, the chain is not lubricated properly. It is for this reason that this part serves its owner for quite a long time.

Undoubtedly, during operation the chain must be systematically lubricated, so oil must flow continuously onto its surface. Since this is the entire direct design of the instrument.

During operation of the device, oil directly begins to come out of the tire groove and is immediately absorbed by sawdust.

That is why the process of lubrication of the chain area is carried out automatically . The chainsaw does not supply oil to the chain. Youtube channel of Korinevich. But it is worth noting that there are models that have a so-called “dosage” of oil, which must be supplied directly to the chain. And naturally, models whose price category is quite low have only a manual pump that operates directly through the action of a drive, which is located on the handle.

Choosing the right oil

After you purchased the device, you immediately had a question: what kind of oil should you put in your Stihl chainsaw? If you properly care for equipment intended for work in the construction and gardening industry, you can significantly increase the level of activity of the direct operation of the device itself without encountering breakdowns of various types. Correct lubricant It is worth noting that the most important factors in the immediate performance of the device is the use of the correct lubricant and fuel . Although the main problems for owners of this equipment arise precisely with the choice of oil for their “favorites”. At this point you can find out how to select a lubricant specifically for Shtil chainsaws.

First of all, what I would like to draw your attention to is the fact that almost all chainsaws from this manufacturer have a carburetor two-stroke engine. And also in their “arsenal” there are two direct tanks, namely: gasoline and oil. In order to choose oil for a Stihl chainsaw, you need to know certain criteria for this type of choice.

Firstly, do not forget that, for example, domestically produced chainsaw models require the use of only simple oils that are used directly for motorcycles, and their proportion should not exceed 1:25. And instruments that are manufactured abroad require branded oils, since their requirements are significantly overstated. And remember that such oils for imported tools must contain a proportionality of oil and gasoline equal to 1:40.

In fact, if you look at it this way, then only you, as the owner of the equipment, can determine which oil to use. Naturally, you can pour oil from a domestic manufacturer into an imported chainsaw. But then you must be prepared for the fact that the power and productivity of your tool will be significantly reduced. Motor oil In addition, it is worth noting that there is no definite answer as to what kind of oil is supplied to the chain of the Stihl chainsaw. Basically, the owners of this type of device use motor oil, and if this is not available, then they use transmission oil.

If you believe the experts, essentially any oil can be used, even the one you pour directly into a Lada car, but there are certain peculiarities, namely: for the Khurstavna brand, motor oil can be used, but for Calm only transmission oil can be used.

Moreover, to choose the right oil you need to know what color it should be . Since, for example, for chainsaws with a two-stroke engine, the oil should be red, blue or green. Moreover, when you buy oil, you must take into account what specific oil composition is recommended by the manufacturer of your equipment.

In addition, you can greatly facilitate the purchase for yourself and purchase a special oil for the Stihl chainsaw, the price of which is so high and which was produced by “your” manufacturer. During operation, the chain was therefore not calm at the enterprise. And then you can be sure that your chainsaw will not cause any malfunctions. Of course, you can buy cheap oil, but it's worth it to then complain that your chainsaw didn't last you long enough.

List of the best

Now let’s actually get acquainted with the most optimal oils, both in terms of quality and price category, that are widely used for chainsaws from the manufacturer Shtil. And let’s directly give them a short description, so:

This kind of oil is widely used directly for small four-stroke engines. It can be used regardless of the time of year, but you must remember that the air temperature should not be lower than 15 °C. This oil is sold directly in bottles with a capacity of 0.6 liters and costs around 360 rubles.

Oil for two-stroke engines 100 ml

This oil can be bought in a bottle with a capacity of one hundred milliliters for only 90 rubles. It must be added directly to gasoline. The ratio of their quantity should not exceed 1:50, that is, 20 grams. oil and one liter of gasoline.

Moreover, this kind of lubricant was developed specifically for the equipment of the manufacturer Shtil. Its main component is minerals. But it can also be used in other models from other manufacturers. The main thing is that these chainsaws have a two-stroke engine.

Stihl oil for two-stroke engines 1l

The weight of the container in which the oil is sold is equal to one liter. It is intended directly for Stihl chainsaws, but can also be used perfectly for tools from other manufacturers. Diluted directly with gasoline 1:50. The chain on the chainsaw is not lubricated. And the basis of this oil is minerals. This kind of assistant will cost you around 500 rubles.

Stihl oil for two-stroke engines 1l. with dispenser

Sold in a bottle with a capacity of one liter and which has a direct dispenser for three and five liters. Diluted with gasoline in a direct ratio of 1:50. The oil was made specifically for two-stroke chainsaw engines from the manufacturer Shtil. It is also made on the basis of mineral additives.

Signs of a malfunctioning lubrication system

The correct choice of consumable lubricant and flawless operation of the system contribute to complete lubrication, effective cooling of sawing equipment and the complete exhaustion of its service life.

There are several external signs that the chain on a chainsaw is not lubricated. First of all, this:

constant oil level in the tank;
increased load on the engine;
accelerated wear of the cutting edges of saw links;
characteristic smell of overheated wood.

In the simplest version, the cause of oil starvation may be clogging of the oil channels with sawdust. This drawback is typical for budget headsets that do not have convenient access to problem areas.

Reasons for decreased system performance and efficiency

The required amount of oil is not supplied to the chainsaw chain for several reasons. The most common failures include:

clogging of the filter located in the oil tank;
mechanical failure of one of the pump worm drive elements;
In winter, the performance of the blower is reduced due to filling the system with too thick oil.

In the latter case, the drive and all pump parts operate under increased loads, causing serious mechanical damage.

Feature of independent troubleshooting

A complete independent repair of chainsaw chain lubrication, all things being equal, requires knowledge of the interaction of all elements of the system, the availability of tools and plumbing skills.

Restoring the operating parameters of many chainsaws involves partial or complete dismantling of the component equipment. To perform complex repair work, it is better to use the capabilities and technical potential of service workshops.

Parts with broken threads and damaged spline joints, as well as non-separable structures that come with the lubrication system of popular Shtil 180 chainsaws and other similar models must be replaced.

If, when the tank is filled, oil does not flow into the headset structure, the reason should be sought in the pump itself. Dismantling and disassembling the mechanism will help identify faulty parts and eliminate the problem by replacing them.

Checking the system for oil output and performance

A dirty oil filter results in a significant reduction in pump performance. It is easy to check this parameter. To do this, you need to hold the headset of the saw running at working speed over a clean sheet of paper.

Based on the density and size of the oil strip, you can confidently judge the condition of the system and the complexity of the upcoming repair.

To the question why the repaired lubrication system works, but the chain does not receive oil in the required quantity, there is no definite answer. The reason for the failure may be errors made during assembly, failure of standard adjustments, or a discrepancy between the density and viscosity of the selected composition and the declared characteristics.

Oil starvation of the headset is possible when installing a longer productive bar on a household saw with a non-regulated pump, which is included with professional-class chainsaw equipment.

Specifics of repairing Chinese chainsaws

A significant share of the imported chainsaw range is made up of Chinese-made chainsaw equipment. Many models have been copied with greater or less success from the best European designs.

The main advantage of Chinese products in the budget segment is the high level of interchangeability of spare parts, components and systems. To repair Chinese chainsaws, in some cases, you can use components from models from other manufacturers that are identical in power and purpose.

The chainsaw chain is not lubricated

During long-term operation of a chainsaw, some of its elements and components may become unusable.

Advantages of higher class oil pumps

The maintainability of dismountable pumps is sufficient to restore the operation of the unit at home.

The pump drive gears of budget chainsaws are mostly polymer. Advanced in terms of technical equipment, proprietary models with adjustable performance are equipped with drive mechanisms made of non-ferrous metals. The cost of such systems is compensated by economical, up to 50%, consumption of working fluid.

How to adjust the oil supply to the chain in a regular chainsaw. Proper lubrication of a chainsaw chain

One of the most vulnerable components is the oil pump. In this regard, many saw owners have a question about how to repair the oil supply on a chainsaw.

The job of the oil pump is to supply lubricant to the chain - this is necessary for its smooth movement along the guide bar. When the oil pump fails, the chain's lubrication is impaired, which reduces the chainsaw's efficiency. In some cases, this leads to a circuit break. To prevent negative aspects, it is necessary to timely repair the oil supply. How to do it?

Preventative maintenance of chainsaws

Sharpening the saw is done independently using tools and a file or on a sharpening machine. It is produced when cutting edges are worn out or minor chips on the teeth.

Filters are changed periodically in accordance with the manufacturer's recommendations. Air, oil and fuel cells are subject to renewal.

Spark plugs are replaced after a certain time, guided by operating requirements.

Refueling. Different manufacturers and engine types determine the composition of the fuel mixture - a 2-stroke or 4-stroke gasoline engine is filled with gasoline with or without the addition of oil.

More complex work - repair of the piston group, gearbox, clutch, etc. - is carried out as events occur. Such work is usually carried out in specialized repair shops.

A properly configured chainsaw is the key to safe and highly productive work. Remember this!

Do-it-yourself chainsaw carburetor adjustment

For an independent carburetor option, you need to familiarize yourself with its structure and understand the procedure for the work that is carried out to adjust the parts responsible for the proper functioning of the components of the device and parts close to it.

It is necessary to carefully handle items for the system option, and also to determine whether the set characteristics correspond to very acceptable values.

Operating principle and design of the pump

Oil pumps can be made of metal and plastic. They are also divided into two types, which differ in their design:

The pump is driven by the movement of the drive sprocket. While the chain is moving, oil is supplied to a special channel located on the guide bar. At idle speed (when the drive sprocket does not rotate), the pump does not supply lubricant - this is done to save money.

The speed and volume of lubricant supplied to the chain directly depend on the number of sprocket revolutions. Some models of chainsaws have a manual adjustment system using a special screw located on the body of the device. On expensive models of saws, the oil supply is automatically regulated during operation.

Main problems with oil supply

When operating a chainsaw, two types of problems with the supply of lubrication to the chain can be observed:

Insufficient oil flow, which can be caused by various reasons. If measures are not taken in time, the quality of work will noticeably deteriorate, and the chain itself may become completely unusable.
Excessive amount of oil. In this case, after prolonged use, puddles of grease may accumulate under the saw. This not only affects oil consumption, which will have to be constantly added, but also negatively affects the environment.

Both of these problems need to be addressed as soon as possible after they are discovered. This will extend the life of the saw and reduce lubricant consumption.

Troubleshooting

If oil is supplied to the chain in excessive quantities, not only while the saw is running, but also at idle, manual adjustment should be made (if the pump design allows this possibility). This is done using a screw, which is located on the body near the guide bar, usually on the bottom or side. Tightening the screw reduces the oil supply, loosening it does the opposite. If the adjustment does not help, it is necessary to check the serviceability of the pump, and also inspect the tire - perhaps a gap has formed at the point where it connects to the body, through which oil flows past the chain.

Lack of oil can be caused by several reasons, each of which has its own solution:

Oil pump malfunction. As a rule, it consists of an unsuitable gasket. In order to replace it, it is necessary to carefully disassemble the pump so as not to damage its moving parts. Next, a new gasket is installed, after which the pump is assembled and installed in place.
Broken oil supply hose. If the pump gasket is in good condition, or if replacing it did not lead to results, you should check the tightness of the hose. If it is faulty, it needs to be replaced. Otherwise, it would be a good idea to clean it and seal it with sealant.

If the reason does not lie in a breakdown of the pump, it is necessary to inspect all conductive holes and channels for blockages, and, if necessary, clean them of foreign objects. This can be done with a jet of compressed air.

How to repair a chainsaw

To repair a chainsaw, you need to become familiar with its internal structure, the operation of all mechanisms, and study the lubricant supply system. When the chainsaw is running, the following problems may occur.

Oil leakage is often observed.

The tightness of the hoses may be broken. To solve this problem, you need to disassemble the tool and replace the hoses. If there are no spare parts, you can degrease the old hose and its seat. Install self-tightening clamps at the connection between the hose and the tube. The field of this tightness will be restored.

Sometimes the oil filter gets clogged. It needs to be cleaned periodically. The oil supply can only be repaired if the chain is dry. This usually occurs due to clogged channels. They must be thoroughly cleaned. This phenomenon occurs very often.

When it is difficult to start a chainsaw, and sometimes it is simply impossible, you need to diagnose the device. First, the spark plugs and air filter are checked. All parts must be thoroughly dried before reinstallation.

Chainsaw fuel system: 1 - fuel filter, 2 - carburetor, 3 - manual pre-priming pump.

If there is fuel on the spark plugs, we can talk about its excess. The main cause of this problem is poor carburetor adjustment or improper starting. The fuel supply valve may be closed. To fix the breakdown, you need to make sure that there is enough fuel in the gas tank and check how well the combustion chamber is functioning. If the spark plugs become unusable, they must be replaced.

The fuel supply may have stopped due to a clogged breather. A vacuum forms in the gas tank, which blocks the fuel supply. This phenomenon occurs when the channels are clogged, the carburetor is poorly adjusted and the air filter is clogged. These problems require repair of the valve, which equalizes the pressure during the supply of gasoline. The breather is cleaned with a sharp needle.

To adjust the carburetor you need to find the optimal speed value. To do this, you need to tighten or, conversely, unscrew the adjusting screws. This setting must be performed exactly according to the Shtil chainsaw repair instructions.

The filter mesh in the carburetor is cleaned, all channels are purged, the functionality of the membrane is checked, no ruptures are allowed.

Due to its complex mechanism, work with the carburetor must be carried out carefully and in perfect cleanliness. Its normal and good work depends on this.

To ensure proper operation of your chainsaw, you need to constantly care for it. It requires constant cleaning of the air filter and lubrication of the chain, and always with new, fresh oil.

When the tool is put away for long-term storage, it is necessary to drain all gasoline and remove chain oil. In this case, the chainsaw will work without breakdowns for a long time.

Adjusting the Oil Supply to the Chainsaw Chain Partner

Most modern oil pumps for chainsaws are designed the same way: in the body (photo 1, item 1) there is a cylinder (photo 1, item 2), into which a plunger is inserted (photo 1, item 3), which performs rotational and translational movements in it.

The cylinder in the lower part has two holes (in photo 1, position 4, only one of them is visible): oil is sucked in through one, and oil is pushed out into the second.

The plunger (photo 2) is a steel rod, on one side it has a milling groove - a flat, and on the other a plastic or steel gear. As the plunger rotates, the flat alternately opens and closes the inlet and outlet ports of the cylinder. When moving upward, the flat first opens the inlet (while closing the outlet) and creates a slight decrease in pressure. Due to this, a portion of oil is sucked into the cylinder. Then, turning, the plunger moves downward, opening the outlet hole with its flat surface (while closing the inlet hole) and pushing the oil out of the cylinder. So it is fed to the tire in small portions. Due to the high cycle frequency, a constant and continuous flow of lubricant is created.

Two types of oil pumps are used (photo 3): with adjustable oil flow and with unregulated flow. In the first case, the plunger gears have an oblique tooth, and upward translational movements are provided by an additionally installed spring. The oil flow is controlled by changing the stroke length of the plunger in the cylinder. Example - oil pump for Chinese saws with an engine capacity of 45-52 cc

In the case of a non-adjustable oil pump, the plunger has an oblique closed groove into which the fixed stop of the housing rests. Rotation causes the groove to slide along the stop, and since it is oblique, this movement causes the plunger to move back and forth. With this scheme, it is impossible to limit the stroke of the plunger and oil is supplied in constant quantities. Example - oil pump of Husqvarna chainsaw 137, 142

The torque from the engine to the plunger is transmitted through a special drive , which also has a gear - the mating part of the gear on the plunger. In fact, this is a pair of worms. The oil pump drive is driven either by the chain drive sprocket (photo 4, item 1), or by the crankshaft itself (photo 4, item 2).

In the first case, the plunger is mechanically connected to the drive sprocket and rotates only with it. Photo 4, item 1 shows the drive of the Stihl MS-180 chainsaw. The steel tendril clings to a special groove on the drive sprocket cup. When the sprocket rotates, the drive rotates along with it. At idle speed in this case there is no oil supply.

In the second case, the drive is rigidly fixed to the shaft and constantly rotates with it. Photo 4, item 2 shows the oil pump drive of the Husqvarna chainsaw 137, 142. It is pressed onto the crankshaft shank and rotates constantly with it. Therefore, oil is constantly supplied, even if the saw is in idle mode.

Typically, one of the gears (either on the plunger or on the drive) is made of plastic in order to protect a part with a more complex design or complex installation. The plastic part will be the first to break and wear out.

On some saws, the oil pump with the drive can be additionally closed with a special cover (photo 5, oil pump cover of a Chinese chainsaw 45-52 cc), which protects the worm joint and the pump itself from dirt and wood dust. On some saws, such as Husqvarna 137, 142, the oil pump housing itself covers the connection between the drive and the plunger, thereby serving as a protective cover.

The bar and chain require a certain amount of lubrication to function properly.

Video: Adjusting the Chainsaw Oil Pump

When the segment of the segment at the end of the plunger opens the oil inlet port of the mowing line, the plunger moves slightly out of the working chamber of the pump, thereby capturing oil from the mowing line through the open hole.

When the piston rotates further, the inlet port of the pump oil chamber is blocked and the outlet port of the exhaust port is opened. At the same time, the piston slides in and pumps the trapped oil into the oil supply channel to the piston's lubrication point.

For one revolution around its axis, the plunger makes one reciprocating movement along its axis, the magnitude of the stroke of which is adjusted by a screw with an eccentric mounted transversely at the end of the piston rod. Some people like to call it a fist.

READ How to Roll a Band Saw

The eccentric is located next to the central protrusion at the end of the plunger shaft, and the greater the angle of deflection of the adjusting screw, the further the eccentric located on it will push the piston shaft away from itself. When the eccentric deflection is greatest, oil cannot be pumped. No chain lubrication.

In addition to the central protrusion, at the end of the plunger shaft there is an annular protrusion with a profile surface, which determines the size of the plunger along its axis. That is, the level of oil capture and injection.

A metal spring is installed on the plunger shaft, which, pressing against the oil pump body on one side, constantly presses the piston shaft against the adjusting screw.

The profile surface of the annular protrusion is in contact with the cylindrical body of the adjusting screw. At the point of their contact, a mother is formed, which, when the plunger shaft rotates, sets a value that limits the movement of the plunger along its axis and affects the process of capturing and pumping the plunger.

The oil pump will operate at maximum efficiency provided that the cam of the adjusting screw does not contact the center boss on the end of the plunger shaft. When the adjusting screw rotates, the eccentric moves toward the lug and pushes the piston shaft away from itself. In this case, the amount of oil supplied by the oil pump will depend on the position of the eccentric relative to the boss on the piston shaft, and in this example, the amount of oil supplied by the pump is controlled.

Malfunctions of the plunger oil pump of a chainsaw and their elimination.

It often happens that oil is not supplied to the saw chain, even if the adjusting screw is at maximum oil supply. There are not many reasons:

After disassembling the oil pump, the adjusting screw is set to position 180 approximately relative to its original position.

It is enough to rearrange the adjusting screw or leave it this way. Then the positions of the screws for maximum and minimum oil supply () will be changed.

The surface of the profile of the annular protrusion is worn out and looks more like a flat surface rather than a profile. The plunger does not move along its axis.

Replace the oil pump or profile and grind the center lip on the end of the plunger shaft. In this case, the volume of the pump chamber will increase slightly.

When adjusting the profile and protrusion, it is necessary to maintain the same maximum height dimensions relative to each other, so that when the adjusting screw is positioned in the minimum mode, the piston pumps little oil. The new pump has a central protrusion at the end of the plunger shaft above the level of the annular profile by about 0.3. 0.6 mm, and in the position of the adjusting screw with minimum oil supply, the oil pump does not work,

Deterioration of the inner surface of the pump plunger chamber and the outer surface of the plunger.

READ Setting Up an Adjusting Machine for Band Saws

This usually manifests itself in a previous defect or something I will describe below. We replace the oil pump or select kits based on the size of those used.

Violation of the tightness of the working chamber of the plunger.

Oil can be applied lightly to the lubrication point, but there is a lot on the chain drive side of the drive housing.

The last example talks about a plunger collar, which in many cases is installed in the opposite direction, with the clamp facing outwards. Some masters claim that this is a cuff that retains oil in the pump chamber. But how does this cuff behave when inflated? Will the oil pass through?

Some people opt for rubber rings instead, but trust me, it is not easy and very careless for the inexperienced. This method is good, but you need to consider the tightness of the O-ring. If the ring is securely seated, the plunger spring will need to be replaced and increased wear will occur at the interface between the adjusting screw and the plunger shaft. There will also be added wear on the pump drive worm steam assembly.

The ease of movement of the plunger is supported by the use of a cuff, which does not interfere with the return stroke at the moment when the plunger captures oil and maintains sufficient tightness of the working chamber when pumping out oil.

At the first opportunity when chainsaws come to me, I always disassemble the oil pump to be completely sure of the condition of the plunger and its collar. If the seal is installed with the seal on the outside, install it opposite, with the seal facing the working chamber of the oil pump plunger.

This is my method, which always works, provided that no one interferes with the design of the oil pump and the oil is supplied to the pump through the oil filter.

adjusting the oil supply to the chainsaw chain

In order for the existing design of the lubrication system on a chainsaw to produce it, the oil must have a suitable viscosity. Judging by the mechanics, the oil pump does not care what kind of oil you use: automobile, transmission or special. The main thing is that the viscosity is within the established acceptable range. However, this does not mean that you can pour any oil. The purpose of chain oil is not to save you money on buying it, but to lubricate the parts of the bar and chain. Different oils cope with this task differently. But more on this in another article “Chain oil. What to pour?

No Oil Supply to Chainsaw Chain

Why doesn't oil flow to the chainsaw chain?

If during operation the chainsaw chain does not receive oil, you need to find the cause of the problem. chainsaw chain lubrication. No oil is supplied to the chain. Oil is not supplied to the chain. Same story, sun carden 1800 electric saw. I don’t understand why the oil doesn’t go to the chain, there’s a pump there. Husqvarna chainsaw repair. 4.5 why the chain on a chainsaw is not lubricated. In fact, there can be many reasons influencing this process. You should disassemble the chainsaw and identify the main problem. The probable prerequisites for this process will be described below.

There may be several reasons for the lack of oil supply to the chain when the chainsaw is operating, and to identify them, you need to disassemble the chainsaw.

Possible reasons for fuel failure

Oil may not flow to the chain only if there are two breakdowns. The electric saw rotates during sawing and no oil flows to the chain. These include:

problems with air leaks;
failure of the oil pump drive.

Basic parameters of a chainsaw chain.

The second reason is a breakdown of the oil pump drive. Regarding the carburetor settings on the chainsaw, the oil supply to the chain is poor, why. In common parlance this part is called a worm. The stihl ms 180 saw does not supply oil to the chain, no matter what you do, disassembling the stihl ms180 chainsaw. When the drive fails, oil will stop flowing to the chain. The oil pump drive is a round plastic ring with grooves inside. Constant use of a chainsaw leads to wear of the internal parts, resulting in the metal hook located inside the drive being chipped. The chain in this photo is not the one I have been working with stems for 2 years and the problem is that the oil is not flowing. After this breakdown, oil stops flowing to the chain.

If the carburetor is adjusted correctly, fuel will be consumed in the permissible amount. Why doesn't oil flow to the chain in a new electric chain saw? Otherwise, it will end too quickly.

You can change the fuel supply manually. The correct operation of the lubrication system is determined by holding the tire up. No chainsaw repair instructions can replace the supply of lubricant to the chain and c. If oil splashes appear, then everything is set up correctly.

It is advisable to make cuts with a significant amount of lubricant. Oil does not flow to the chain of the Titan ETSP-2000 electric saw! I fill in the original oil, the pump is new, the hole is not clogged, but the oil flows under the shield! If you have to work with soft wood, a small amount of fuel is supplied.

The chain should always be well lubricated. The oil is flowing in, there are drips on the tire, there is oil in the chute, and the oil is not getting to the chain. This will avoid smoke and further failure of the entire chainsaw. The main reasons why oil does not flow does not flow to the chainsaw chain. If oil leaks or does not flow at all, it is necessary to identify the cause of the breakdown. It is not recommended to operate the tool until repaired.

Troubleshooting Circuit Problems

During operation of the chainsaw, it is necessary to constantly monitor the lubrication of the chain. After all, it is this part that works in the most difficult conditions. The oil supply is poor and the oil supply to the chain is not universal. If no oil flows to the chainsaw chain during operation, the chain is not lubricated properly. The chain is constantly overheated and dust and abrasive particles become clogged with it. We do not apply lubricant to the chain of the electric saw, tension the chain of the Makita electric saw. All this negatively affects its service life. Let's figure out why oil is not supplied to the chainsaw chain and why oil is not supplied to. A special lubricant will correct the situation. It is supplied to the chain from the tank, thereby ensuring unhindered operation.

The channels through which fuel is supplied can become clogged with small particles, so it is advisable to clean them periodically. Oil does not flow to the chainsaw chain. Oil does not flow to the chain of the titanium electric saw. It is also important to monitor the oil level in the tank. Debris in the channel is a common cause of chain brake failure. Chainsaw stihl ms180 if during operation there is no oil supplied to the chain, no oil is supplied to the chain. This may have a negative impact on your work.

Regular cleaning of the channels and general maintenance of the chainsaw will allow the tool to function for a long time.

But what to do if all the recommendations are followed, but the oil still leaks. It is necessary to ensure that the chainsaw is operating correctly. It is likely that it was assembled incorrectly. If the breakdown has not been identified, it is recommended to take it to a workshop. Husqvarna 137.142 does not repair the chainsaw, the oil on the chainsaw does not flow to the chain. In some cases, it is necessary to replace the pump, but this should be done if the saw is new. Old tools leak due to worn out reservoir.

Only a specialist can assess the current condition of the chainsaw. If you lack knowledge or lack confidence in your own abilities, it is advisable to entrust instrument repair to a professional.
