Partner pours a candle on a chainsaw

All chainsaws of Russian and foreign production are similar in design. Therefore, the repair of different chainsaws does not differ much. Despite its simple design, problems with the chainsaw can occur.

Professional services for repairing chainsaws in Rostov-on-Don are provided by the Alfa-Rost service center.

Repair may be required if the chainsaw:

• does not start;
• stops itself during operation;
• saws badly;
• not working at full capacity.

Depending on the malfunction, repair of the chainsaw engine or repair of other systems and components may be required.

• fuel supply systems;
• exhaust systems;
• ignition;
• cylinder-piston part.

In other cases, it is necessary to repair the clutch, chain brake, tire or lubrication system.

Chainsaw Partner 350: characteristics and features

The Partner 350 chain saw belongs to the class of household or amateur hand-held gasoline saws. Amateur - does not mean a “club of interests” for chain saw lovers, but denotes the power and capabilities of the unit. This saw is one of the best in its class and is optimal for short-term work in the garden, on a summer cottage, etc.

With its help, you will trim bushes, prepare brushwood for the barbecue and wood for repairs, and cut down a small tree. All this is possible due to the following technical parameters:

• Weight: 4.7 kg
• Two-stroke engine power - 1.8 hp. (1300 W)
• Engine capacity: 34 cc.
• Electronic ignition system.
• The capacity of the oil tank is 0.2 l, the fuel tank is 0.4 l.
• Chain pitch: 3/8 inch.
• The maximum chain length is 41 cm, the optimal length is 35 cm.
• Primer for starting a cold engine.

The advantages of the Partner 350 chainsaw are its compact size and convenient operation. It has a built-in safety system: the double inertia brake is activated automatically as soon as an emergency situation occurs. potentially dangerous for the saw operator.

The chain is also automatically lubricated. At the same time, fuel is consumed very economically, and the air filter lasts longer thanks to the CCS system. It’s even surprising that at such high engine speeds the saw operates relatively quietly. As a nice “bonus”, the cylinder walls are coated with a special protective compound, and an anti-vibration system is built into the handles.

As for the shortcomings of the Partner 350 chainsaw , reviews on the forums speak volumes about them. It turns out that this model was first released in 2012 and then re-released in 2015. According to the documents, the updated model is more advanced. But in practice, copies of the first series are more reliable and break less often. In addition, this saw is not equipped with a shock absorber - this can be felt during prolonged use. Partner chainsaws are produced by the Swedish concern Husqvarna, which is well known to users of equipment for gardening, dacha and forestry. Factories producing Partner equipment are located not only in China, but also in the USA, Italy, and Great Britain.

Despite this, the price of Partner chainsaws is relatively low. Spare parts are also available. In Western countries, this brand is very popular due to its win-win combination of price and quality. But even Swedish quality sometimes fails.

Chainsaw Partner 350 repair instructions. Chainsaw Partner 350: faults and their elimination

One of the main features of this saw, its users note durability of operation with a minimum number of failures. And yet they happen. To determine why the saw stopped working, you need to perform basic diagnostics.

If the saw does not start, then:

• there is no spark on the spark plug;
• fuel is not supplied;
• no air coming in.

First you should check for the presence of a spark: by unscrewing the spark plug, connecting it to the high-voltage wire and placing it on the cylinder, pull the starter. If there is a spark, then clean and adjust the gap on the spark plug (0.5 - 0.65 mm). If it is not there, then you need to change: either the flywheel or the coil (magneto). In addition, the spark plug itself may fail or the high-voltage wire may break.

The next step is to check the fuel supply. To do this, you need to disconnect the supply hose from the carburetor and check its presence. Absence may indicate that the fuel filter or delivery system is clogged. The carburetor itself may also become clogged.

If you do not have experience in repairing and cleaning it, entrust this work to specialists.

If the air supply deteriorates, the saw should start, but it will not work well. Remove and wash the air filter. Put it back in place only after it has completely dried.

If the saw starts well, idles and stalls when gas is supplied, the muffler is most likely clogged. Remove, disassemble, wash, put back and continue working.

You can also easily change the saw bar and chain, carburetor, starter, oil pump, ignition and clutch with your own hands.

And you will be able to replace a broken starter cable after watching this video:

We recommend entrusting more complex chainsaw repairs related to replacing the cylinder-piston group or crankshaft to specialists, although if you are familiar with two-stroke engines, then this work will not be difficult for you, and spare parts for Partner chainsaws are not in short supply in Russia.

To enlarge a picture, click on its thumbnail.

We advise you to regularly monitor the serviceability of the safety group: brake and chain catcher. Remember that the saw should be thoroughly cleaned of small chips. It can not only clog technological holes in the oil pump and other places, but also interfere with the operation of the brake.

Operating Instructions for Partner 350

In this manual you will find not only a detailed description of the saw, but also basic techniques for working with the tool. We would like to draw your attention to the fact that this chainsaw can run on AI95 or AI92 gasoline with the addition of oil for two-stroke engines in a ratio of 1:50.

Common Partner saw breakdowns: diagnostics at home

The Partner gasoline saw cannot be called unreliable. For many users it works without problems in winter and summer, for many years. But others complain about the same typical problems:

1. The chainsaw won't start.
2. The chainsaw starts but stalls.
3. Fuel does not enter the cylinder.

All these problems have internal causes in the parts and components of the tool. This means that in order to get to the bottom of it and fix the breakdown, you will have to disassemble the electric saw. This is not as difficult as it may seem, because manufacturers always take this possibility into account.

To independently diagnose problems at home, you need to understand that common chainsaw problems in the vast majority of cases are caused by the same reasons. Therefore, just by the symptoms, you can guess where the source of the problem is.

For example, if a chainsaw does not start , then the reason most likely lies in the ignition system, namely the spark plug. If air leaks into the cylinder, then you need to look for a defect in the fuel system. A dirty filter causes the engine to stall and smoke, and so on. Let's look at these cases in detail so that you feel confident when repairing the Partner chainsaw yourself.

Troubleshooting Tips

Fuel transfusion and filling of a chainsaw spark plug can be one-time and accidental. For example, “over-pumping” with a pump cap (primer): the engine does not start immediately, the operator presses his finger on the cap again and again, tries to start it, then pumps it up again.

In this case, the reason is not at all in the carburetor. You need to unscrew the spark plug and ventilate the combustion chamber by pulling the starter cord several times, as when starting. The candle is wiped, dried on the flame of a gas burner or burner, or another one is used. They check the spark, put the spark plug in place. They try to start it first without choke.

If it does not start after 3-4 jerks, press the pump cap 2-3 times. They try again. That is, after an overflow, it is better not to pump up the fuel first, but to pump it up incrementally. Until the engine starts.

Candles sometimes require their own maintenance and care.

• Inside, around the insulator, there should absolutely be no soot or dirt.
• The contact between the electrode and the plate from the spark plug body is cleaned with “zero” sandpaper. Carefully, without rounding the end of the electrode.
• You need to know the recommended spark plug gap indicated in the instructions for each chainsaw model (from 0.5 to 0.65 mm or more).
• To accurately adjust the spark plug gap, special feelers are used - a fan-shaped set of plates of different calibrated thicknesses, which fold into a handle like a folding knife. Sold in auto tool and spare parts stores.
• When working in winter, it is better to store the chainsaw at low temperatures. When taken out of the heat and into the cold, a sharp temperature change can cause condensation to form everywhere, including in the ignition system, and this is harmful.

What to do if the Partner 350 chainsaw does not start

Now that you know what caused the breakdown , it's time to get down to business. A faulty ignition system can only be repaired after disassembly. To do this, remove any remaining fuel from the tank. Then carefully disconnect the wire and remove the spark plug (a special key is provided to remove it).

1. Test it to see if it works . To do this, place the ignition cable on the spark plug, and connect the spark plug nut and cylinder using pliers. Now start the starter. Is there a spark? This means the spark plug is in working order. No spark? This means that it will not be possible to revive the spark plug, and it must be replaced. What can you do with a working candle? Already by the appearance of the spark plug one can judge the repair method.
2. The candle is completely dry . This means that it is not wetted by the fuel mixture. The problem must be looked for at the stage of fuel entering the cylinder, it is disrupted. The spark plug and the ignition system as a whole have nothing to do with it. Reinstall the spark plug and look for the real cause of the problem.
3. The spark plug is overfilled with fuel mixture . The first thing, of course, is to wipe it with a napkin and put it aside. Now you can look for the cause in incorrect carburetor adjustment. While the spark plug is air drying, you can shut off the fuel supply and turn on the starter to check the combustion chamber. After a few minutes, the spark plug can be replaced in its place in the mechanism and the chain can be restarted.
4. The candle is covered with a layer of soot . Burning occurs as a result of improper fuel composition. There are two options here: either you saved money and filled the chainsaw with low-quality gasoline, or the proportions of the mixture of gasoline and oil were violated. The candle needs to be cleaned properly. To remove a plug from carbon deposits, a needle, thin awl or similar tool from available means will do. The electrodes also need to be cleaned.

In addition, in any case, it doesn’t hurt to make sure that the chainsaw’s carburetor is adjusted correctly. Do not begin adjustments until you have cleaned the air and fuel filters. If the filters are ok, use the adjustment screws.

One of them (S) is intended for idle speed , the other two are for maximum (H) and minimum (L) speeds, respectively. Gradually turn the screws clockwise. After stopping, make two turns in the opposite direction.

What to do if the chainsaw continues to not start?

If the initial inspection did not yield anything or the defects were eliminated during the search process, but the chainsaw still does not start, then you need to look for more serious reasons. It is best to identify and repair such breakdowns at a service center. However, if you have experience, you can find and eliminate them yourself. What to diagnose and check?

• Compression in the cylinder;
• Compression in the crankcase;
• Carburetor operation.

In the first case, checking the compression in the cylinder will allow you to find out the condition of the cylinder-piston group (CPG) of a chainsaw that does not want to start when cold. To do this you need a compression gauge. The device is screwed into place of the spark plug and the engine is started idle. Measuring the readings allows you to judge the condition of the CPG. In the absence of a compression gauge, you can determine the compression in the cylinder offhand as follows:

• Place your finger on the spark plug hole;
• Try to start the chainsaw engine.

By placing your finger on the spark plug hole and pulling the starter, you can check the compression in the cylinder

If you feel that your finger is being pulled strongly into the spark plug channel, then everything is in order with compression. The absence of vacuum in the chamber indicates a malfunction. The cylinder-piston group needs a more detailed inspection, which will give an idea of ​​the condition of the piston and cylinder, piston rings and bearings.

READ How to Assemble a Partner Chainsaw

A chainsaw may not start when cold due to a lack of compression in the engine crankcase. The main reason for this is damage to the gasket located between the cylinder and the crankcase. It is quite easy to detect a lack of compression:

• Disconnect the upper tube from the carburetor;
• Pour gasoline into a regular cork;
• We immerse the removed tube in the fuel;
• We pull the starter several times.

If fuel is sucked out of the cap when the chainsaw starter starts, then everything is fine with compression. If not, look at the gasket.

If the fuel is drawn in, then everything is fine - the gasket is intact. Otherwise, you will have to purchase a repair kit and make a replacement. How to do this, watch the video, why

Chinese chainsaw does not start:

Starting the tool may be complicated by improper operation of the carburetor or its breakdown. It often happens that during the sawing process the fastening screws become loose and air is sucked into the cylinder. Check that the carburetor is securely fastened. Inspect it for fuel leaks. There can be many reasons for the malfunction. It is possible to accurately determine the malfunction, eliminate it and fine-tune the carburetor only at a service center.

After going through a step-by-step troubleshooting of the chainsaw engine, you will be able to find the malfunction, fix it yourself and successfully start your working tool. Do not take on types of work that you are not confident in. Entrust troubleshooting and troubleshooting to specialists from the service center.

Problem: chainsaw stalls after starting

A common situation : the Partner chainsaw stalls at high speeds, although before that it starts and runs without problems at medium gas. Sometimes at medium it also works intermittently - but at full throttle it immediately stalls. This problem is faced by many users who save on quality fuel.

Low-quality gasoline easily contaminates parts with soot. In this case, checking the filters (air and fuel) will not hurt. Moreover, the muffler suffers from poor fuel and the carbon deposits it creates.

The combustion products of dirty fuel simply clog it, forming an impenetrable plug of soot. This plug greatly reduces engine power. In this case, gasoline is consumed in large quantities, but there is no result in power. Check and clean the muffler:

1. Remove any remaining fuel from the tank.
2. Remove the muffler and take it apart.
3. Do not leave the outlet open; cover it with a napkin or lid.
4. Clean all carbon deposits from the muffler using a cable and/or detergent. According to reviews, “Mr. Muscle” for pipes or similar household chemicals has proven itself well.
5. A clean muffler needs to be dried. To speed up the process, you can do this with a hair dryer.

Repairing the fuel system of a chainsaw

When the fuel supply is interrupted , it is not surprising that the chainsaw does not work. Moreover, in this case there is only one problem: no fuel enters the cylinder. And there may be several reasons for this problem, and you have to find that very reason.

First, try disconnecting the fuel hose and observing the fuel pressure. A weak, intermittent flow indicates a clogged filter. Take it out, rinse and dry it, and if possible, replace it with a new filter. Also clear the breather (valve) of any blockages.

Check the condition of the carburetor filter and, if necessary, rinse it thoroughly, dry it and reinstall it. We talked in detail about setting up the carburetor above, and these actions in this case will also not be superfluous.

If the reason is not in the breather or in the carburetor, then everything may turn out to be trivial. Make sure there is enough fuel in the tank.

There may also be problems with the cylinder-piston group (abbreviated CPG) of the Partner chainsaw. This failure can be considered serious because the cylinder and piston are the basis of the engine. Therefore, the CPG is an expensive component, the cost of which reaches half the cost of the entire tool.

on the coordinated operation of the cylinder and piston. During operation, especially if operating rules are not followed, the cylinder, piston and rings may wear out. In this case, only replacing parts will help.

CPG parts may be damaged mechanically. These defects can be diagnosed independently. Remove the muffler. You can see the CPG in the hole. Scratches and scuffs on the surface of the cylinder , located chaotically, occur when debris, fragments, or solid foreign particles enter.

If the cylinder is darkened , and this defect is observed over its entire surface, then, in all likelihood, you filled the chainsaw with low-quality fuel. Bad gasoline also affects oil scraper rings. A worn surface of the cylinder on the muffler side is a sign of critical overheating of the chainsaw during operation. Minor mechanical damage can be corrected by replacing bearings, rings, etc. But in case of deep scuffing, the CPG will have to be completely replaced by contacting a partner chainsaw repair shop.

How to prevent chainsaw damage

Repairing a chainsaw can be very expensive in some cases. This can be avoided if you pay enough attention to the prevention and control of the condition of the instrument and all its parts. Moreover, it is not difficult to fulfill this condition - just use the operating instructions and adhere to rational accuracy:

To keep it in working order, you just need to strictly follow the instructions and follow some general rules:

1. Do not allow the engine to overheat, take breaks in operation so that it can rest and cool down.
2. Do not load the chainsaw beyond the capabilities of its class. For example, if you are using a household grade Partner 350 saw, then it is simply not designed to work for more than 40 minutes a day.
3. Check the chain brake daily (this is done at maximum acceleration).
4. Follow the manufacturer's requirements regarding the quality and composition of the fuel mixture.
5. Check the condition of the spark plug weekly and clean the electrodes if necessary.
6. Before using the saw, make sure the chain is sharp and installed correctly. Pay attention to the wear of the cutting links and sharpen them in a timely manner. Watch for cracks and breaks in the rivets.
7. A properly tensioned chain does not sag, but it can be moved by hand. Never do this with a hot chain! Sharpen and/or tighten it after replacement.
8. When refueling the chainsaw, make sure that dirt and other foreign particles do not get into the tank along with the fuel. Fill oil and gasoline carefully, do not spill them.

Often, when contacting a service center, it turns out that the Partner chainsaw broke down due to improper starting of the tool. Therefore, there is only one universal solution when a saw breaks down: handle it correctly, and most problems can be avoided.

And if you are interested in the reasons for breakdowns of the Stihl chainsaw, the second popular brand together with Partner, then the next article is about exactly that.

If your Partner chainsaw does not start, there is no need to rush to take it in for repairs. Each tool comes with instructions that indicate how to fix the problem yourself.

Why it won’t start and what to do

There may be several reasons why a chainsaw starts poorly or does not start. To install them, you need to diagnose the device. Possible causes of problematic startup:

• there is no spark at the spark plug;
• poor condition of the air and fuel filter;
• poor fuel supply and exhaust channel performance;
• The breather, which is located on top of the tank, does not function well.

Often carbon deposits appear on the electrodes of the spark plug and the tool does not start. Therefore, first check the spark plug. If the reason is not hidden in it, then the remaining elements are examined.

1. To test the ignition spark, you need to remove the spark plug. To do this, remove the tip located on the high-voltage wire, take out the spark plug and put the tip back on. The spark plug is applied to the cylinder and the starter is started. The engine ignition unit is working properly if the electrodes produce a spark when turned on. When there is no spark, you need to use a feeler gauge to adjust the distance between the electrodes or clean the entire part. For the chain saw to start, the distance between the electrodes must be from 0.2 to 0.5 mm.
2. To check the fuel supply, you need to fill the tank with a fuel mixture. The system pipe is disconnected from the carburetor and pumped up. Fuel flows in spurts when the system is working properly. If the supply is weak, clean the channel through which the fuel or filter is supplied. When gasoline leaks appear under the tank cap, this means that the tank is full and can affect engine performance.
3. The fuel filter is checked by disconnecting it from the carburetor. The gasoline supply channel is disconnected and fuel is pumped. If there is no pressure in the pipe, then drain the fuel from the tank and pull out the filter cartridge. It is cleaned or replaced with a new one.
4. The breather valve (valve), located on the fuel tank cap, is designed to equalize the air pressure, which allows gasoline to flow freely into the carburetor. Sometimes it becomes dirty, air does not flow inside and a vacuum is created, which does not allow the chainsaw to start. The hose through which fuel is supplied is disconnected from the carburetor and then checked. Fuel should flow out of the disconnected hose. If this does not happen, then clean it with a simple needle or a stream of air under high pressure.

What to do if a chainsaw

does not start

Have a nice day, dear readers and subscribers of my blog! At one inopportune moment you may find that your chainsaw

does not start.
Alas, don’t rush to immediately hand over the instrument for repair; maybe you can fix this damage yourself. I will tell you what to do when the chainsaw , and how to find the right solution to this problem.

We analyze the probable causes of failure

There is an option in the annotation itself to find out why the tool does not start. But rarely is there an abstract nearby.

Although each model has its own characteristics, the result remains similar to our client. Therefore, I will tell you the probable causes of failure and probable methods of eliminating them for various tools.

How the mechanism works

Almost all tools, both foreign (Husqvarna, Makita, Shtil, Partner 350), and Chinese chainsaws, and Russian (Druzhba, Ural), are designed identically. Therefore, it is very easy to find the reason why the device does not start and stalls.

Of course there are four elements in which problems occur:

• The fuel for which the carburetor is responsible;
• Lubrication;
• The air that enters through the air filter;
• The quality of the spark depends on the ignition unit.

They depend on each other and interact with each other. If any element does not work correctly, the saw stops working.

The first question is that our client has to start the tools differently - hot and cold. Two frequently used mechanisms are responsible for this process.

Be sure to look at what is written in the user's annotation. It indicates that when turning on, you must make sure that the critical stop brake is locked. But starting a saw with a brake is much more difficult, so it’s better not to turn on the brake.

READ Which disc to cut CBPB at home

You can find out from the annotation that inside the body there is a fuel tank and an engine, and outside there is a saw part (bar with chain), a handle and a starter.

First, you need to figure out exactly how the tool won’t start. For example, a saw starts up, but immediately stalls, or loses power and cutting quality.

There may be interruptions in work due to problems in the engine. However, I would not recommend disassembling it right away. It is better to find a problem from the most common option.

It is important to consider the quality of the fuel. If the mixture is prepared incorrectly or has deteriorated over time, then even such reliable tools as the Ural or Husqvarna 145 will not work. The annotation will certainly indicate the proportions and special oil for your chainsaw.

The next common problem is that the user fills the candle at the start time. It needs to be inspected; if it is 100% dry, it means fuel is not passing into the cylinder.

Why is the spark plug in the chainsaw flooded?

A parody on the topic, -Carburetor is absolutely synonymous with the concept of,,jamb,,!!! Unhealthy, what hurts you? Carburetor.

If you see dark carbon deposits or a lot of fuel, then the carburetor may not regulate the fuel supply correctly.

If your saw tool starts up, but unfortunately immediately stalls, then the problem needs to be found in the carburetor jet or fuel filter. They are clogged for you.

To check whether the breather is damaged, you need to disconnect the fuel hose from the carburetor and see if the fuel mixture leaks out with its use.

If the saw does not start when hot, then you will like the problem better in the muffler. When it becomes clogged from the exhaust itself.

READ DIY Chain Saw Attachment

Quite often, saw breakdowns occur due to a small amount of chain lubricant. This happens when the channels are clogged, also called a leaking oil pipeline.

Also inspect the connections of the pipes with the oil pump fittings to see if they are leaking.

It’s very bad when a breakdown occurs in the cylinder. When examining it, you can find bulges in other chips, and you will like this more because of the difficulty.

Restoring the operation of the tool

To get the saw working again, it doesn’t really matter whether the saw is Ural or Shtil, you need to know the location of the breakdown.

First, we check and change the unusable fuel mixture. If the saw does not start as before, then we check further on Fri.

There is a problem with the candle - pull it out and dry it. In no case should you pierce it, this will lead to a malfunction of the part. Half an hour after drying, you can insert the candle back, first checking to see if there is any fuel left in its place.

In addition, the spark plug may simply break, so it is better to have a spare one to rule out the cause.

Another reason that the tool does not start well and stalls is poor contact between the spark plugs and the high-voltage wire. If our client remains fine here, but there is no spark despite this, the ignition unit itself has broken down. The only way to fix such a breakdown is to replace it.

Air filters need to be inspected and cleaned from time to time. If you have not inspected it since the moment of purchase, it could become clogged with dust and cause a malfunction.

In models such as Shtil 180, Ural or Partner 350, the breather becomes clogged, which often leads to breakdown. To clean it, use a sewing needle.

For models Shtil 180, Druzhba, Ural and Husqvarna 142, when the muffler becomes clogged, it also needs to be inspected and cleaned.

READ Chainsaw Ural Electron won't start

If there is a problem with the carburetor, then without the appropriate experience it makes no sense to try to fix it. It is much better to turn to specialists.

If, after checking and eliminating the problems listed above, your saw still does not start, then the breakdown is probably hidden in the cylinder group.

When, during inspection, you notice damage and chips on the piston or cylinder assemblies, these elements will have to be replaced.

If the reason for the malfunction of the chainsaw is pipes that are leaking, then the insufficient amount of lubricant is probably supplied to the chain. To eliminate the problem, just replace the tubes and seal the joints with sealant.

Mechanism parts are designed to last forever, so from time to time they will have to be changed. To find out how long each part lasts, you need to look at the annotation.

Separately about the breakdown of the most common model

Let's look at the difficulties of Shtil 180 in more detail:

1. Clogged carburetor or fuel filter. These are the most common problems that are not at all difficult to eliminate after cleaning. From time to time the filter has to be changed;
2. Changing the spark plug;
3. From time to time the cylinder or seals need to be replaced.

The Shtil saw is quite strong and durable, so of course you can often remove a breakage yourself. Almost the same applies to the Partner , Ural, Makita and Husqvarna models.

When we detect a malfunction in our own chainsaw, we look for the cause from a small point of view, regularly checking and eliminating problems. Such problems can be easily removed without the help of others. If the breakdown is severe and you do not have enough experience, then this should be done by a specialist.

If it starts and stalls

When a chainsaw starts and stalls, it is due to the carburetor or other parts. Causes of malfunction:

1. Fuel is not getting to the engine well. This occurs due to a clogged breather.
2. There is not enough fuel in the tank. By tilting the tool sideways, the remaining fuel flows into one place. Because of this, the saw stops working.
3. Fuel is of poor quality.
4. The spark plug insulator overheats when poor contact is made between the wire cap and the spark plugs. The contact between them becomes worse due to carbon deposits or mechanical shear.
5. Spark plugs are faulty.
6. Fuel does not flow well to the carburetor through the fuel filter or pump. As soon as the tool starts to increase speed, it immediately stalls.
7. If the air filter is dirty, the engine cannot withstand high loads and stops.
8. Insufficient or no lubrication in the chain.

Partner R-350 won't start!

Stalls when you press the gas

If the chainsaw stalls when you press the gas, then you need to inspect the gasoline and air filters, as well as the fuel pump.

1. During operation, the air filter becomes severely clogged, and when you press the gas, the tool stops working. The filter is dismantled, cleaned or washed with warm water, dried thoroughly and only then installed back. Then disconnect the fuel hose screwed to the carburetor. Gasoline should flow out through it. The hose is cleaned or replaced with a new one if the liquid does not leak out. The filter is working properly and you don’t need to check it if the gasoline flows well.
2. The chainsaw stalls - the gasoline pump may have worn out. If gasoline flows through the walls of the pump, it means that the device has stalled because of it. This part is replaced with another.

In order for the chainsaw to start, you need to accurately determine the cause of its malfunction, and then try to fix it yourself. If the problem is not found or you cannot fix it yourself, then it is better to seek help from specialists.

Amateur and professional chainsaws are complex devices. The motor life of their two-stroke engines, components and assemblies has its limitations. For this reason, quite reliable and expensive tools, along with cheap Chinese units, periodically fail and refuse to start. The situation when a chainsaw does not start or stalls is not very pleasant and sometimes confuses the user. How to identify and eliminate the malfunction, restoring the functionality of the tool.

  continues to not start?

Checking the condition of the fuel and air filters.

If the fuel quality is fine, the chainsaw engine may not start due to clogged fuel and air filters. To diagnose these elements, you will need to perform a number of manipulations associated with their dismantling.

For fuel filter:

• Disconnect the gasoline supply line from the carburetor;
• Pump up the fuel.

If there is little or no pressure in the pipe, disconnect the filter. Before doing this, empty the tank of the mixture and remove the filter element itself. Dismantling is done using a wire hook. A clogged replacement cartridge that causes poor starting of the chainsaw engine can be cleaned, but it is best to replace it with a new one. When using the tool in dusty conditions, cleaning should be done on a regular basis.

A clogged air filter can cause the chainsaw engine to run rough, causing it to stall or be difficult to start. Dust and dirt deposited on the adsorbent material make it difficult for air to enter the system, making the fuel mixture so rich that it will sometimes be difficult to start the tool.

READ Husqvarna 365

Checking the air filter is one of the first steps in finding the causes of poor starting.

Removing the air filter should be done with caution, since dust accumulated on its surface during operation of the saw can get into the carburetor. And this is fraught with more expensive repairs. After disconnecting the cartridge, thoroughly clean it of accumulated dirt and wash it with detergent. Dry the element and carefully put it back in place.

To determine the reason why the chainsaw does not start or stalls when starting, it is necessary to troubleshoot the tool. The essence of the procedure is a sequential inspection of the condition and operation of the main working elements of the saw engine. At this stage we check:

• Presence of a spark on the spark plug;
• Fuel supply;
• Filter status;
• Operation of the breather built into the fuel cap of the stalling unit;
• Functioning of the exhaust channel.

Checking the spark on the spark plug and eliminating the causes.

The first step in finding the reasons why a gasoline saw does not start is to check the spark on the spark plug. There are many factors that influence the operation of this element. However, the main ones at the initial stage of tool troubleshooting are:

• Incorrect carburetor adjustment;
• The presence of more than the required amount of oil in gasoline;
• Air filter clogged.

All of them contribute to the formation of carbon deposits on the spark plug electrodes. In 50 cases out of 100, saws do not start when cold due to the lack of a spark due to carbon deposits on the electrodes and their corrosion. The result is either a decrease in the gap or an increase in it.

Checking the spark plug of a non-working chainsaw

Checking for spark is quite simple. To do this you will need:

• Remove the tip of the high-voltage wire;
• Unscrew the spark plug;
• Put the tip back on;
• Place the candle skirt against the cylinder;
• Start with the starter.

If at the moment the chainsaw engine starts, a good spark is observed between the electrodes, then everything is in order with the ignition unit. If it is not there, then it is worth cleaning the element itself and checking the electrode gap. If necessary, use a special probe to adjust the distance between the contacts.

For spark plugs from different manufacturers, the distance between the electrodes may vary. For some it may be equal to 0.5 mm. Others have 0.2 mm. Therefore, carefully study the manufacturer's recommendations.

There may be no spark at the spark plug for other reasons. The main malfunctions that affect poor starting of the chainsaw and unstable operation of the internal combustion engine at idle, which can cause the tool to stall, include the following:

• Overfilling of the spark plug channel with fuel;
• Lack of contact between the high-voltage cradle and the tip of the spark plug;
• Failure of the ignition unit.

How to start a cold chainsaw if the spark plug channel is constantly flooded with gasoline? You can fix the problem while starting the tool using the following algorithm:

• Unscrew the spark plug with a special wrench;
• Wipe it with a clean and dry cloth;
• Dry for 20...30 minutes;
• Remove carbon deposits with a file and adjust the gap between the electrodes;
• Drain the remaining fuel from the spark plug channel and dry it;
• Collect everything and try to start the mechanism.

As a rule, these measures are quite enough to start the chainsaw and get the job done. However, this extreme measure does not eliminate the main reason why the engine does not start or stalls - improper operation of the carburetor, which needs fine adjustment.

If there is no spark due to poor contact of the high-voltage cradle with the tip of the spark plug, it is necessary to check the connection. The test can be carried out using a regular tester. If a defect is detected and corrected, the chainsaw should start without any problems.

If the check shows that the contact is reliable, but the saw still does not start, look for the reason in the ignition unit. As a rule, a faulty unit cannot be repaired or restored. This will require a complete replacement.

We determine the availability of fuel and its supply.

First, you need to make sure that there is a fuel mixture in the tank of the chainsaw that does not want to start, and that it is properly supplied to the carburetor. With a full tank, check how the mixture is supplied through the gas line. We disconnect the fuel system pipe from the carburetor and try to pump it up. In case of complete order, when pumping, gasoline will be supplied jerkily in accordance with the standards set by the manufacturer. Weak fuel supply or its absence can result from:

• The fuel supply channel is clogged;
• Fuel filter clogged with debris.

Often the cause of poor starting of a chainsaw can be a too full tank. In this case, you should pay attention to the presence of smudges under the saw housing cover. If they are present, then look at the connection of the gasoline supply pipe to the carburetor. Most often, it is squeezed out by pressure when screwing on the tank cap, which is tucked right under the neck, which prevents the engine from starting.

What to do if the chainsaw does not start

Have a nice day, dear readers and subscribers of my blog! At one inopportune moment, you may find that your chainsaw will not start. Why does the spark plug on the chainsaw light up? The answer is simple: this happens when the unit starts. But don’t rush to immediately hand over the tool for repair, maybe you can fix this damage yourself. I will tell you what to do when the chainsaw does not start, and how to find the right solution to this problem.

We analyze the possible causes of failure

You can find out why the tool does not start in the annotation itself. But the abstract is not always at hand.

Although each model has its own characteristics, in general they are all similar. Therefore, I will tell you the probable causes of failure and probable methods of eliminating them for various tools.

How the mechanism works

In fact, all tools, both foreign (Husqvarna, Makita, Shtil, Partner 350), and Chinese chainsaws, and Russian (Druzhba, Ural), are designed identically. Therefore, finding the reason why the device does not start and stalls will not be particularly difficult.

There are four elements where problems can arise:

• The fuel for which the carburetor is responsible;
• Lubrication;
• The air that enters through the air filter;
• A spark, the quality of which depends on the ignition unit.

They all depend on each other and interact with each other. If any element does not work correctly, the saw stops working.

Let's start with the fact that all tools start up differently - hot and cold. adjusting the carburetor why the spark plug on the chainsaw fills up the Ural chainsaw. Two commonly used mechanisms are responsible for this process.

Be sure to look at what is written in the user manual. It states that when turning it on, you need to make sure that the emergency stop brake is engaged. But starting a saw with a brake is much more difficult, so sometimes it’s better not to turn on the brake.

READ Why The Chainsaw Doesn't Speed ​​Up

As you can find out from the instructions, inside the body there is a fuel tank and an engine, and outside there is a saw part (bar with chain), a handle and a starter.

First you need to figure out exactly how the tool won’t start. If the spark plug on a chainsaw is filled with gasoline, solving this problem is quite simple. To do this you need to follow the basic rules. For example, the saw starts up, but immediately stalls, or loses power and cutting quality.

Perhaps interruptions in operation occur due to problems in the engine. But I would not recommend disassembling it right away. Why does the carburetor stihl ms 660 in the Urals 2t fill the spark plug on a chainsaw? How to distinguish. It is better to look for the problem from the simplest option.

It is very important to consider the quality of the fuel. If the mixture is prepared incorrectly or has deteriorated over time, then even such reliable tools as the Ural or Husqvarna 145 will not work. Why does the spark plug on a chainsaw fill? youtube. The instructions must indicate the proportions and special oil specifically for your chainsaw.

Another common problem is that the user fills the candle during startup. It needs to be inspected; if it is completely dry, then fuel is not passing into the cylinder.

READ Chainsaw Chain Does Not Supply Oil

Quite often, saw breakdowns occur due to a small amount of chain lubricant. This happens when the channels are clogged or the oil line is leaking.

Also inspect the connections of the pipes with the oil pump fittings to see if they are leaking.

It is very bad when a breakdown occurs in the cylinder. Fills a candle on a chainsaw. solution to the problem. When examining it, you may find unevenness or chips, and this may be the cause of the problem.

Restoring the operation of the tool

To restore the operation of the saw, no matter the Ural or Shtil brand, you need to know the location of the breakdown.

First, we check and change the unsuitable fuel mixture. If the saw still does not start, then we check further point by point.

The problem is in the candle - we pull it out and dry it. Under no circumstances should you pierce it, as this will lead to a malfunction of the part. Fills a spark plug on a chainsaw: what to do? 30 minutes after drying, you can insert the spark plug back, first checking to see if there is any fuel left in its place.

In addition, the spark plug may simply break, so it is better to have a spare one to rule out the cause.

Another reason that the tool does not start well and stalls is poor contact between the spark plug and the high-voltage wire. If everything is in order here, but there is still no spark, the ignition unit itself may be broken. Such a breakdown can only be corrected by replacing it.

Air filters should be checked and cleaned from time to time. If you have not checked it since purchase, it could become clogged with dust and cause a malfunction.

In models such as Shtil 180, Ural or Partner 350, the breather becomes clogged, which often leads to breakdown. To clean it, you can use a sewing needle.

For models Shtil 180, Druzhba, Ural and Husqvarna 142, the muffler sometimes gets clogged, it also needs to be checked and cleaned.

If the problem is in the carburetor, then without appropriate experience you should not try to fix it. It is best to turn to specialists.

If, after checking and eliminating the above problems, your saw still does not start, then most likely the breakdown is hidden in the cylinder group.

When, during inspection, you see damage and chips on the piston or cylinder assemblies, these elements will have to be replaced.

If the cause of a chainsaw malfunction is pipes that are leaking, then most likely there is not enough lubricant supplied to the chain. To fix the problem, just replace the tubes and seal the joints with sealant.

Mechanism parts cannot last forever, so they will have to be changed periodically. To find out how long each part lasts, you need to look at the instructions.

Separately about the breakdown of the most common model

Let's look at the problems of Shtil 180 in more detail:

1. Clogged carburetor or fuel filter. These are the most common problems that can be easily resolved after cleaning. Sometimes the filter has to be changed;
2. Replacing the spark plug;
3. Sometimes the cylinder or seals need to be replaced.
