Chainsaw Lesnik 2512: review, instructions, reviews, adjustment

Adjusting the Chainsaw Carburetor Lesnik

Setting up a chainsaw carburetor with your own hands
To make your own 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.

About the carburetor design

The carburetor serves to mix the flammable mixture with air while maintaining predetermined proportions. If clear doses are not followed, the proper operation of the engine is at risk. When a huge amount of air enters during mixing of the components, but there is not enough fuel, then such a mixture is considered “lean”.

Oversaturation should not be allowed, because with a larger amount of fuel compared to air, malfunctions or engine wear are also likely. Carburetor adjustment is needed not only before initial use, but also when any differences in its operation are detected. Before working with a chainsaw, do not forget to run it in.

Carburetor components

What you need to have for setup

Each carburetor owner must have the necessary tools to adjust this system. There are three adjustment screws that are located on the body of the device. They have their own markings:

L - screw for correcting low speeds.
H - screw for adjusting high speed.
T - regulates idle speed, in most cases used for experiments.

Chainsaw air filter

Before adjusting the carburetor, you need to prepare the device:

The engine warms up, that is, it starts about 10 minutes before repairs, and turns off when starting work (see how to start a chainsaw).
The air filter is checked and washed.
The chain is stopped by turning screw T until it stops (see chain oil).

To carry out a safe repair, you need to prepare a flat surface where you can carefully place the device and turn the chain in the opposite direction. Need a tachometer. It determines whether there is a malfunction in the carburetor. When turning the screws, the sound should be perfect and absolutely smooth. If you notice squealing notes, the mixture is oversaturated.

Setup instructions

Carburetor adjustment is divided into two main stages. The first one is called basic. It is performed with the engine running. The second is performed when the engine is warm.

To carry out the carburetor setup procedure successfully, you need to read the operating instructions for a specific model in advance to identify additional features of setting up the device.

First stage

The adjusting screws for the highest and lowest speeds should be moved clockwise until the highest resistance is met. When the screws reach the stop, you need to move them in the opposite direction and leave them 1.5 turns.

Main stage

Care, assembly, adjustment of the Lesnik chainsaw

How to adjust the carburetor on a chainsaw

The engine is turned on at medium speed and warms up for about 10 minutes. The screw responsible for adjusting the idle speed should move clockwise. It is released only when the engine reaches stable operation mode. It is necessary to ensure that the chain does not move during this process.

In idling mode, the engine may stall (the reason is here). In this case, you must immediately turn the adjusting screw clockwise until it stops. Sometimes the chain starts to move. In this case, turn the adjusting screw in the opposite direction.

Checking acceleration operation

Need to do a little research. Acceleration of the device is initiated. It is necessary to evaluate the proper operation of the engine during maximum speed. When the engine is functioning correctly, it means that when you press the accelerator, the speed quickly increases to 15,000 rpm.

If this does not happen or the increase in speed is too slow, you must use the screw marked L. It turns counterclockwise. Moderate movements must be observed, since the turn cannot be more than 1/8 of a full circle.

Maximum number of revolutions

To limit this indicator, you need to use a screw marked H. To increase the number of revolutions, turn it clockwise, and to reduce them in the opposite direction. The maximum frequency should not exceed 15000 rpm.

If you make this figure larger, the device’s engine will wear out, which will lead to problems in the ignition system. When rotating this screw, you need to take into account the ignition processes of the device. If the slightest malfunctions appear, then the maximum speed value must be reduced.

Final check at idle

Before this procedure, it is necessary to carry out a full adjustment of the carburetor components when operating at maximum speed. Next, you should check the functioning of the device in idle cold mode. When the correct adjustment parameters are achieved, you will notice that the carburetor design closely matches the following criteria:

When the idle cold mode is activated, the chain does not move.

Chainsaw accelerator

When the accelerator is pressed even slightly, the engine accelerates at an accelerated pace. With gradual deepening of pressure, you can notice that the engine speed increases proportionately, reaching the maximum permissible values.
When the engine is running, you can compare its sound to a four-stroke device.

If violations are noticed in the given parameters or the device has not been fully adjusted, you need to perform the main setup step again. Sometimes actions are performed incorrectly. In this case, the device may fail due to the loss of the correct node settings. In this case, you will have to contact a specialist.

Disassembling the carburetor if necessary to check or repair components

The design of different carburetor models is almost the same, so when working with them you can use the standard scheme. All elements must be removed carefully and then laid out in the order given below so that you can successfully place the items in place after the completion of the repair work.

Removing the Top Cover

The top cover is removed. To do this, you need to unscrew the 3 bolts holding it in a circle.
The foam rubber is also removed, since it is the upper component of the filter that conducts air.
The fuel hose is removed.
The drive thrust is output directly to it.
The cable end is disconnected.
The gasoline hose can be completely removed if you systematically pull it off the fitting.

To finally prepare the carburetor for major repairs or replacement of the smallest parts, you need to carefully disconnect it from the main system. Sometimes further disassembly is required. You should unscrew the components carefully and put the fasteners in groups, as these small parts are easily lost.

Instructions for Chinese

To correctly configure the carburetor of a Chinese chainsaw, you must first remember the factory settings of the device, then turn on the engine. Subsequently, you will have to leave it running for several hours in order to accurately set your own parameters. Sometimes work is carried out only after ten minutes of engine operation, but many Chinese-made models require special handling.

Adjustment procedure:

Activities begin in idle mode. Using the adjusting screws, you need to achieve a systematic increase in engine speed, so you should first let it run at low speeds. A deviation from the norm is the movement of the chain along the bus. In this case, you need to adjust the outer screws to the optimal position so that the chain remains motionless.
The transition to medium speed speed is carried out. Sometimes the engine starts to smoke. This defect can be eliminated by tightening the screw to supply a leaner fuel mixture.

In this case, the smoke will disappear, but the engine speed will increase. You need to adjust the settings until you reach a level where, when you press the throttle, the engine smoothly picks up speed, and no sudden jerks or interruptions are heard.

At sub-zero temperatures the engine may stop starting. You have to pull the starter dozens of times before the saw starts.
The saw is no longer produced, so it will be difficult to purchase spare parts.

For a budget model, this chainsaw has surprisingly few shortcomings.

Chainsaw Lesnik 4518 – capabilities and equipment

This semi-professional model is actively used when caring for large gardens, as well as for cleaning forest tree poles before further felling. The Lesnik chainsaw in this configuration is often used by employees of public utilities and rescue services.

The model is powered by a 2-stroke gasoline engine with an air cooling system and a cylinder capacity of 45 cm3. The inner walls of the latter are coated with a protective chrome-plated composition, which prevents the formation of rust. Starting the internal combustion engine is done using a simple but fairly reliable manual starter. The engine crankcase is made entirely of metal, which makes it resistant to various mechanical shocks.

For convenient operation of this chainsaw, the manufacturer has included in its design an effective vibration damping and noise suppression system. This allows you to work with the tool for a long time without feeling tired.

The saw adjustment and switching buttons are located at the rear of the saw. This frees up the operator's left hand and makes it possible to cut wood more accurately, both crosswise and longitudinally.

User manual

Acquaintance with any equipment begins with instructions, Forester 2512 is no exception. But most people ignore this. In the case of a chainsaw, ignorance of operating features and safety precautions can end in disaster. Therefore, before starting work, you must read the operating instructions for the device.

Because Forester 2512 is a copy of the Patriot PT 2512 chainsaw, so the instructions from it are quite suitable. You can download the instruction manual in our catalog.

Possible malfunctions and repairs of a chainsaw

Forester 3816 suffers from all the childhood ailments inherent in his brothers from the Middle Kingdom. From basic tire wear to carburetor and engine breakdowns.

Problems with the bar and chain can occur almost immediately after purchase. It is recommended to replace with high-quality ones from OREGON. If the tire does not last for the first time, it is better to throw out the chain immediately. According to numerous user reviews, it stretches like plasticine.

Engine malfunctions are very rare and in most cases are due to wear and tear or manufacturing defects. But problems with the carburetor are not uncommon.

To diagnose carburetor breakdowns, it is better to use the operating instructions; it describes all possible faults and how to eliminate them. Upon completion of the repair, the carburetor will need to be adjusted. This is not so easy to do. Our article on setting up or the same operating instructions for the Lesnik 3816 chainsaw will help with this.

An interesting video about caring for a chainsaw, the nuances of cleaning it from dirt, which will extend the life of the tool. The author also talks about adjusting the idle speed on the carburetor. Everything is clear and in accessible language.

Among analogues worthy of competing with the Lesnik 3816 chainsaw, it is worth noting the following saws:

It is impossible to say definitively that any of the listed chainsaws are definitely better than Lesnik 3816. Each tool has its pros and cons. There are successful examples of using specific saws for several years, and there are also unsuccessful chainsaws that cause a lot of problems from the first day.

Similar chainsaws

Among budget models with such a displacement, the chainsaw has enough competitors. You can make models such as Champion 125 T-10 and HUTER BS-52:

Champion 125 t-10 - at the same price, this chainsaw weighs more and has less power. Nevertheless, users note reliable and trouble-free operation, as for a budget model;
HUTER BS-52 - Forester, multiplied by two. Twice the power, twice the weight, twice the price. Unfortunately, reliability leaves much to be desired - despite the price, for many users the saw simply does not start.

If your household needs a more powerful chainsaw (but still in the budget segment), you should pay attention to the AL-KO BKS-3835. Although the price is almost twice as high (8,000 rubles versus 4,500 for Lesnik), the assembly and quality of the model are also an order of magnitude higher, and the price/quality ratio is better than that of the BS-52.

Purpose of the chainsaw

The chainsaw has a compact size and a low-power engine, which immediately gives an idea of the purpose of the Lesnik 2512 saw:

clearing the area for development;
cutting thin wood (up to 20 cm);
use on long hiking trips that run through difficult forests.

Also suitable for users who rarely use a chainsaw and need it more “just in case”.

Reviews from real owners

For informational purposes, we suggest reading the reviews left by visitors to our site through the comment form.

Nikita: In the first hours after the purchase, my joy knew no bounds - the Lesnik 2512 chainsaw worked like a clock! All the branches and twigs in the area flew off to the sides, all you had time to do was wave and saw. Unfortunately, the saw couldn’t handle the larger branch—it simply stalled and wouldn’t start. It turned out that the wire had come loose from the ignition coil. I returned it to its place, and the saw came to life - but now I handle it extremely carefully. In general, she copes with her tasks.

Valery Nikolaevich: China as it is. I fell for the cheap price and positive reviews. In the forest, the Lesnik 2512 chainsaw is of no use - already on the second log it begins to “choke.” Okay, if you can’t pull logs, let’s try you on branches. But even here there was a bummer - branches of small diameter were sawed at such a speed that it was easier to saw them with a hacksaw. The experience of using it is extremely negative, I would not recommend it to anyone. The only advantage is its light weight, but the chainsaw should work and not just be carried around in your hands.
