Chain saw partner 350 DIY repair

In detail: partner 350 chainsaw DIY repair from a real master for the site my.housecope.com.

For people engaged in construction or logging, as well as living in their own living quarters with an adjacent plot of land, it will be very useful to own a quality Swedish chainsaw "Partner 350", which is an excellent substitute for other tools for cutting wood, for example, two-handed saws or hacksaws ...

Like any other units, chainsaws also require careful maintenance and periodic maintenanceotherwise they will quickly break down as a result of exploitation. At the same time, contacting qualified specialists with a request to fix a chainsaw costs money, which you may not want to spend for any reason, because you understand that you can fix most of the faults and breakdowns yourself. To do this, you need to understand the structure of the chainsaw and watch a video where you will receive detailed instructions for repairing the Partner 350 chainsaw.

The vast majority of product malfunctions occur due to engine problems and related systems. Usually, to repair the unit, it should be disassembled. In order not to make a mistake during the disassembly process, read more about the design of the chainsaw in the video or operating instructions.

When your chainsaw won't start, you should first see if are the candles in good working order, giving a spark, due to which the fuel ignites and by force of an impulse pushes the piston, which does useful work.

In order to assess the condition of the candle, you need to remove the wire going to it from the starter and unscrew it with a suitable key from the groove. Examine the candle: its appearance will tell you what happened to the chainsaw:

The consequence of such malfunctions is the inability of the fuel to penetrate into the cylinder and begin to carry out useful work on the rotation of the chain, therefore the chainsaw will not start... The reasons for this are as follows:

Video (click to play).

The fuel filter is out of order because it is clogged.
The breather is clogged (this is the name of the hole made by the manufacturer in the gas tank and designed for air to enter the tank through it).
Lack of fuel in the gas tank.
The diaphragm in the carburetor is not complete, or there is a high probability of blockage in the carburetor passages.
Carburetor adjustment is not correct.

To determine if the breather or filter is clogged with foreign objects, you will need to disconnect from the mountings fuel hose and see if gasoline flows from it and with what pressure. If gasoline comes out slowly and weakly, clean the breather with a thin, sharp object, such as an awl. If the problem is with the filter, remove it from the fuel tank and clean it, and replace if necessary.

Did you find that the carburetor is the root cause of your problems? The good news here is that if your carburetor filter gets clogged, you can easily clean it yourself. In addition, you can easily do the adjustment and tuning of the carburetor of the Partner 350 chainsaw with your own hands, if you strictly adhere to the recommendations from the instruction manual.

The bad news is that with other, more complex carburetor repairs, you are unlikely to cope with your own hands, and you will have to take your unit to the mechanics. Sometimes the manufacturer deliberately does not write in the instructions, how to tune and repair a carburetorso that people who do not understand the device of the product do not try to fix the malfunction on their own if the chainsaw suddenly stops starting and, as a result, does not completely break the unit.

To the main breakdowns of this system chainsaws include:

Low pressure detected by the cylinder compression gauge, which causes the motor to lose power and cannot rotate the chain at the speed necessary to cut wood efficiently. The pressure at which the engine runs smoothly is approximately nine atmospheres.
Loss of tightness of the rings in the pistons, due to which hot gases from the cylinders enter the crankcase. The malfunction is eliminated by replacing the rings.
Problems with the tightness of the gaskets located in the cylinder head (cylinder head). Visually expressed in the form of emissions of gasoline combustion products through the slots in the gasket and the pressure drop in the engine. The problem is solved by replacing the gaskets.

If you want to know if there are problems in the cylinders, then the easiest way to do it is remove the muffler and assess the situation, looking through the hole left over from the removed muffler at the insides of the cylinders. In the event of the need for repairs, of course, you will need to remove the cylinder head for open access to the pistons and cylinders.

Sometimes, having accelerated your chainsaw to high engine rpm, you are surprised to find that the engine cannot cope with them, and your tool stalls. At the same time, smoke begins to pour out of the muffler. However, the motor runs easily at low revs.

In this case, there is a high probability that the muffler of your unit clogged with carbon and other products of incomplete combustion of fuel, therefore it must be cleaned. This work is done as follows: you will need to remove the muffler from the chainsaw and disassemble it; then clean its outer and inner surfaces from carbon deposits; in the last step, dry with a hair dryer and place on the chainsaw.

Please note that it is recommended to cover the muffler opening with a plug or rag to avoid clogging of the cylinders with debris.

Chainsaw "Partner" 350 is a productive and reliable chainsaw from the "Partner" brand. This manufacturer is part of the group of companies of the Danish concern "Huskvarna", which significantly influenced the quality and functionality of the equipment it produces.

Easy to operate and convenient, this chainsaw will come in handy for summer residents and gardeners. And the low weight and compactness do not create restrictions for the transportation of the tool.

The considered modification of the chainsaw has a modern design and decent ergonomic and operational characteristics. The diagram of the external device of the "Partner" 350 chainsaw is given below.

clutch cover;
fuse for the right hand;
throttle lever;
throttle stopper;
universal key;
saw headset tensioner;
primer.

The power component of the device is a single-cylinder 2-stroke engine running on a fuel mixture. Reinforced piston group, large torque reserve, efficient air cooling system extend the service life of the device. With a cylinder volume of 34 cm 3 and a 3.2 cm piston stroke, the chainsaw generates a rated power of 1.3 kW. This is enough to create a high cutting speed in both horizontal and vertical directions.

economical engine;
two-circuit air cleaning system CCS;
electronic ignition;
manual fuel pump;
emergency brake for the saw headset;
high quality cutting part from the Oregon brand;
automatic chain lubrication.

Traction - 1.5 kW;
Engine speed range - 3-13 thousand rpm;
Fuel tank - 0.25 l;
Oil tank - 0.15 l;
Guide - 400 mm;
Chain - 52 links with a 3/8 pitch;
Weight - 4.6 kg.

The 350 comes standard with a 52-link Oregon 91P052E chain. After wear, you can replace it with the same blade, or with others:

Husqvarna 5776151-22;
Stihl 39970000052s.

It is important that the number of links is not within the range of 46-52 pieces.

According to the operating instructions, before starting the Partner 350 chainsaw, it undergoes special training, which includes:

installing a saw headset or checking its tension for already installed parts;
checking the serviceability of the brake band;
putting the brake lever in a ready state as shown in the figure;

filling the oiler and gas tank with fuels and lubricants. The fuel mixture is prepared in a ratio of 1:50 from oil for 2-stroke engines and unleaded AI-92 gasoline.

The launch is carried out on a flat surface, sharply pulling the throttle cable. With a cold start, open the air damper and allow the chainsaw to warm up. Only after that you can gain momentum and move on to woodworking.

All the possible nuances of adjusting the Partner 350 chainsaw with your own hands are detailed in the operating instructions. If they are not observed, the tool is not immune from malfunctions and repairs, the budget of which can be unpredictable.

The most vulnerable systems of the 350th chainsaw from the Partner brand are:

If the engine runs badly or does not start at all, the reasons may be as follows:

lack of gasoline or air intake;
no spark to ignite.

For a more accurate analysis of the situation, you must:

- make sure the fuel reaches the carburetor section - if not, then:
  - the saw's gas tank is empty:
  - float needle clogged;
  - air access to the fuel tank is cut off;
  - the petrol filter is clogged. These breakdowns are eliminated by cleaning the cleaning systems, refilling the chainsaw with high-quality fuel.
  - if gasoline reaches the carburetor, examine the plug for defects - it must be dry and with the correct gap. By its external state, one can judge about possible malfunctions of the entire instrument (see the figure below).
  - If, when connected to a grounded wire, it does not spark, the problem is in the spark plug itself, which may need to be replaced. In addition to the spark plug, other spare parts often fail - the ignition coil or switch;
  - detecting a wet candle is a sure sign that the candle is flooded. This could be due to:
    - incorrect or failure of the factory settings of the carburetor;
    - filling the carburetor block with fuel.,
    In any case, the carburetor settings need to be updated.
  The situation when the chain lubricant spontaneously flows out of the chainsaw body and does not reach the cutting parts indicates that it is not necessary to repair the oil pump, clean the oil supply pipes or replace them with serviceable spare parts. In addition, grease drips can indicate a depressurization of the connection between the pipes and the oil sump. If these breakdowns are not eliminated in time, the chain will overheat, stretch out and prematurely fail.
  
  Do-it-yourself repair of the Partner 350 chainsaw should be performed only by people who understand its structure and the principle of operation.Only in this case can one hope that the replacement of the drive sprocket or crankshaft will be performed correctly and safely for further work.
  
  Almost every summer resident or villager has a chainsaw in his arsenal, the partner 350 model is especially popular. However, sometimes this tool fails. If you are faced with such a problem, then do not despair, because its mechanism is so simple that you can even do the repair yourself. The article discusses the main causes of breakdowns and their elimination.
  This model is in great demand among consumers, but most often it is bought by summer residents to work on their plots. The saw is used not only for harvesting firewood, but also in construction.
  In general, the Partner 350 chainsaws are distinguished by their compact dimensions. They are equipped with a sufficiently powerful engine. Their main advantages are - easy start-up and reliable operation, carried out due to a high-quality electronic ignition system and a fuel pump.
  
  It is completely safe to use such a chainsaw. It has a built-in security system that automatically performs overrun brake start for the chain. Its lubrication is carried out in the same mode.
  
  With the launch of the chainsaw, the Partner will not have problems even in winter, since it has fuel primer... The starter drum is equipped with an impeller to help clear dirt. In addition, the manufacturers have supplied the tool with the CCS system. This design traps residual particles, and is also used for long-term use of the air filter.
  
  To increase the service life of the chainsaw on the cylinder of the piston group, the developers made chrome walls... This model also has an ergonomic handle and anti-vibration system.
  
  Chainsaw malfunctions can be conditionally divided into groups:
  - Malfunctions in the engine (ignition, exhaust and cylinder-piston systems, fuel supply).
  - Failure of components such as clutch, chain brake, lubrication system or tire.
  Chainsaw engine breakdown occurs more often than others. Most of the time is spent on its detection and repair. As a rule, it boils down to such manifestations when the engine is unstable or completely stalls, the engine does not start, does not develop power.
  
  Before you start repairing a chainsaw, first check for all possible causes of violations in its functioning, and even better, watch the video. Fortunately, today on the Internet you can find any material of interest.
  
  Then you have to prepare the necessary tools for repairing breakdowns:
  - device diagram (should be included in the delivery set);
  - keys, including spark plugs.
  When the engine refuses to work, but at the same time there is a spark on the spark plug, and fuel is supplied, check the ignition.
  It is not at all difficult to check it: unscrew the candle, and adjust the gap between the contacts, connect it to the wire and press it against the cylinder body. After that, watch for a spark.
  
  If any deviations occur, you need to perform tuning the ignition system... In general, this process is similar to adjusting the ignition in other two-stroke engines.
  
  To establish a similar malfunction of the chainsaw, it will turn out when inspecting the spark plug. Fuel may not flow into the cylinder for various reasons:
  1. The fuel filter in the tank is heavily clogged.
  2. The hole in the filler cap is clogged, preventing gasoline from flowing out.
  3. There is little or no fuel coming out of the carburetor.
  In the event that there is no correct ratio between the gasoline and the air mixing in the carburetor, or there is insufficient fuel flow, you should check whether the channels and the air filter of the carburetor are not clogged. In addition, it may need to be adjusted.
  
  The filter is carefully removed before cleaning and washed with detergent, after which it is left to dry. Then it is put in place.
  
  Carburetor adjustment carried out, as a rule, with screws - maximum and minimum revolutions. When carrying out it, you must strictly follow the instructions for repairing a chainsaw, otherwise you can damage the engine. Sometimes manufacturers leave only one adjustment screw to prevent inexperienced craftsmen from interfering with the carburetor.
  
  If debugging didn't fix anything, then it's worth doing cleaning of channels and filter mesh, and also check the integrity of the membrane.
  
  Do not forget that a carburetor is one of the complex mechanisms of a chainsaw, so you need to approach it responsibly when cleaning and disassembling it.
  
  It consists of many small elements that can pop out unnoticed and it will be difficult to find them. Often after disassembling this device, some users cannot reassemble it.
  
  If the chainsaw engine functions normally at low speeds, but at high speeds it smokes and stalls, then the reason is most likely in the muffler. Dismantle it first, but remember to close the outlet.
  Then disassemble and clean off carbon deposits dry method or detergents, dry with a hairdryer, assemble and install.
  
  Do not dry clean without special protective equipment, as carcinogens in the soot are released as dust. It is very dangerous to inhale it. When operating a chainsaw, it is necessary to monitor the quality of the fuel mixture.
  
  Need to lubricate the chain regularly during the saw operation, because it works in extremely difficult conditions. Its service life is negatively affected by abrasive particles, dust and even overheating.
  
  If you leave the chain dry, it will soon happen. pulling and overheating... In the worst case, jamming can occur, that is, the sprocket breaks off. Oil is supplied through it through channels, which are quite often clogged with sawdust. They should also be cleaned regularly.
  
  In addition, constantly clean under the cover of the chainsaw from debris and sawdust, as this may not apply the chain brake. In addition, dirt has a bad effect on the performance of the device.
  
  The most serious malfunctions are considered scratches on the surface of the piston and cylinder, their damage, sinking of the piston rings in the grooves, breakdown of the crankshaft bearings.
  Most of them lead to the inability to start the engine, since pressure in the cylinder drops... There are several options for repairing and checking the condition of the cylinder-piston group (CPG).
  
  For example, you can measure the compression in the engine... For this operation, a compression gauge is used, which is mounted in the spark plug hole. Thus, the condition of the parts of the CPG can be checked.
  
  To view the side of a cylinder, it is necessary to remove the muffler and look into the opened gap. Although review is limited, the general condition of CPH can be seen.
  
  For an accurate assessment of the performance of the cylinder-piston group, you will have to completely disassemble the engine chainsaws. First, the crankcase is disconnected from the cylinder, after which the piston is pulled out. If it has chips, scuffs and large scratches, then it needs to be changed.
  
  Low compression occurs most often when coking and damage to the piston ring. Be sure to check that there is no carbon deposits on it. In addition, it should sit freely in the piston groove and be pressed against the cylinder surface.
  
  In general, you always need keep your chainsaw clean and different holes. This is the only way to avoid many breakdowns and further repairs. Be sure to watch the video on how to do it correctly.
  
  Each of these defects is accompanied by certain "symptoms" that will help to accurately diagnose the problem.
  
  Checking the spark in the Partner 350 chainsaw is carried out by removing this element from the saw, and then connecting it to a high voltage wire. Correct operation of the candle is always accompanied by the release of a spark, so this parameter will be easy to track.
  
  Malfunctions in this area can be caused by the following damage:
  - malfunction of the candle itself;
  - weakening of contact in the wired network;
  - breakdown of the ignition button;
  - lack of ventilated passages between parts in the ignition system.
  Fuel is the main source of energy for the saw to operate, so malfunctions in the fuel handling area can cause breakdowns. Checking fuel in a chainsaw Partner 350 is the first stage of diagnostics. If the tank is full enough, it is worth taking a close look at the candles. If the spark plug is dry, no fuel is passing through it. After finding this fact, you need to check all the elements of the system, starting with the carburetor.
  
  The cause of the malfunction is as follows:
  - failure of the cylinder-piston group of the engine;
  - overheating of the piston and cylinder;
  - ingress of foreign particles into the engine.
  If, after the test fuel supply, the Partner 350 chainsaw turned on, then the problem lies in the other elements of the saw.
  
  The saw support shaft should be checked for stability through the crankshaft bearings. The piston connecting rod and bearings must be firmly attached to the frame. If, during the movement of the piston, gaps are observed between the individual parts of the mechanism, then these elements must be replaced.
  
  To disassemble the Partner 350 chainsaw, you will need a number of specialized tools:
  - key;
  - part for fixing the piston;
  - Torx hex fasteners;
  - a bolt for driving out nuts (drift);
  - locksmith's kit (screwdrivers, hammers, reamers).
  The first step in disassembling the saw is to remove the outer profiles and unscrew the covers. Use a cordless drill to remove the air filter and starter covers. Additional fasteners (in the form of screws) are unscrewed with screwdrivers. After removing the cover modules, it is worth cleaning the internal lines of the Partner 350 chainsaw from dirt and dust. Removing the saw motor should be done very carefully, because this mechanism is responsible for the operation of the unit.
  
  After the engine, remove the muffler and flywheel. At this stage, you will need a special piston bolt. The chainsaw clutch is removed in the direction of the chain movement for the convenience of further assembly. The oil pump drive is located under the clutch; it must also be removed.
  
  Removing the flywheel from the crankshaft using a special punch is common among private craftsmen. The bolt firmly grips the main flywheel screw and speeds up the removal process. The flywheel is removed from the shaft by blowing a hammer on a drift.
  
  Assembling the chainsaw Partner 350 is carried out in the reverse order. When returning each part of the saw to its original position, it is worth checking the fixation of all fasteners and the entry of the nuts into the grooves. A feature of the saw motor design is that the main body cover is installed without a gasket, the gaps are protected by applying a layer of a special hermetic material. Before applying the sealant, it is worthwhile to clean the surface well to distribute the product evenly.
  
  The installation of the flywheel must be carried out as delicately as the process of removing it.For the part to function properly, there must be clearances between the mechanism and other parts of the saw. The ignition coil must be connected to the flywheel in such a way that they do not touch each other, but are coupled using magnetic contacts.
  
  With correct disassembly, it is easy to repair the Partner 350 chainsaw with your own hands. Repair of each group of breakdowns is carried out depending on the structural features of the faulty elements.
  
  If there is a malfunction of the cylinder-piston group, it is worth removing all parts from the crankshaft. It is important to know that the piston is connected to the supporting frame using a piston pin. This fastening element must be removed with a screwdriver. The defective piston is removed, and a new one is installed in its place, which is later placed in the cylinder. For lowering
  
  friction, all parts are lubricated with engine oil.
  
  The shaft housing must be to the left of the flywheel arrow, and the recommended backlash must be observed between the elements. The serviceability and quality of the shaft with a new piston must be checked before operation.
  
  Malfunctions in the operation of the oil pump can always be eliminated, and in the event of a malfunction of the oil pump of the Partner 350 chainsaw, this element should be replaced with a new one. The design of this part is a sprocket driven pump coupled to the clutch.
  
  Before removing the oil pump, the chainsaw covers are first unscrewed, and then the piston is fixed and the clutch is loosened. Replacement of the drive sprocket is carried out by installing a new part through needle bearings. The sprocket must be placed on the shaft, after having lubricated its frame.

  - Malfunctions are associated with the accumulation of a large amount of oxygen or the presence of insufficient fuel.
  - Interruptions in operation are noted if there is an increased fuel consumption, leading to a large emission of exhaust gases, which oversaturated the fuel mixture.
  - An unexpected malfunction often occurs when there are mechanical breakdowns. So, in the presence of strong vibrations, a similar problem may arise, the protective cap is damaged. Vibration loosens the fastened bolts.
  - Wear on the piston area of the motor. This problem can be eliminated only by replacing the damaged element. Then you need to configure the node.
  - Interruptions in the operation of the partner 350 carburetor may occur when using low quality fuel. This problem causes the filter to be damaged. To eliminate this situation, it is necessary to disassemble, flush the working units.

  It is important to run the factory device in a timely manner and set it up in time before starting the working process.
  
  The main components of a carburetor are:
  - Main part. It is a special tube designed to allow air to pass through. There is a damper with the ability to change the location.
  - Diffuser. This is the narrow area of the tube. It is necessary to accelerate the flow of air-type mass.
  - Fuel supply channel. The fuel is stored in a float chamber. From there, it goes into the nozzle and then into the atomizer.
  - Camera. It is similar in shape to a container. Maintains the required amount of fuel.
  To set up and repair the saw, we need tools - screws L, H, T, diagram.
  
  Competent tuning of the partner 350 chainsaw carburetor will eliminate the occurrence of the above problems. This work begins with disassembly. Adjusting the carburetor of the partner 350 chainsaw requires knowledge of the information on the design of the working unit.
  
  Further, adjusting the carburetor of the equipment partner 350 with his own hands implies the following list of actions:
  
  A chainsaw is now indispensable in the household. The most popular model for domestic use is the Partner 350 saw. It is easy to use and available for purchase. But it will last longer if the Partner chainsaw is repaired in time, lubricated parts and high-quality fuel is used.
  
  The efficiency of any tool directly depends on compliance with the rules for its use. This primarily concerns the launch. This must be done in the following sequence:
  1. Start the chain brake by pressing it forward.
  2. Remove tire protective boot, if present.
  3. Turn on the decompression valve to facilitate starting.
  4. Press the fuel suction. This is necessary to reduce the number of swaps.
  5. Set the combined lever to idle start up all the way down, having previously blocked the gas lever.
  6. Place the tool on a flat surface, take the chainsaw with both hands so that the cutting part is located at a distance from this surface. In this case, place your left hand on the handle, and your right hand at the starting cable.The tool must be secured with your foot, for which you can simply step on the rear handle.
  7. Now the starter rope must first be pulled, and then pulled several times. In this case, you need to move upward from the body.
  8. As a result of a short start, the motor will stall. Therefore, after that, the combination lever must be moved up one click, and then start again.
  9. If the engine is running, the throttle lever must be pressed, and the combined one must be put into idle mode.
  10. Now the chain brake must be removed and the tool can be used.
  Despite the simplicity of the process, situations may arise when the chain saw still does not start. The reasons are not always related to tool breakage. Perhaps not enough force was applied. If, nevertheless, after several attempts, the launch was unsuccessful, it is worthwhile to conduct a thorough inspection of the device.
  
  The effectiveness of the repair also depends on the correct diagnostics, because a quick identification of the problem will save time on repair work. If the Partner chainsaw does not work, then the diagnosis is carried out in three stages:
  - spark check;
  - checking the presence of fuel in the cylinder;
  - diagnostics of bearings.
  Most often, chainsaw problems are associated with the fact that there is either nothing to burn with or nothing to set fire to. Therefore, first you need to check the plug, for which you need to unscrew it, and attach the wire to the cylinder, and then pull the starter. A spark may be absent due to a defective spark plug, a broken wire in the power circuit, a malfunctioning ignition button, or the lack of a gap between the flywheel and the coil (the flywheel key from the crankshaft may also break). Due to the lack of a spark, the chainsaw can start, but immediately stalls when you press the gas.
  
  If there is a spark, then the fuel system requires checking, especially if it was found that the spark plug is dry. Diagnostics is as follows. Pour 5 ml of fuel through the plug hole, and then start the saw. If the launch is unsuccessful, then the CPG may wear out, a foreign body may enter it. If the saw starts up, then the problem may lie in the improper operation of the carburetor or fuel line.
  
  Chainsaw diagnostics Partner also includes checking the crankshaft bearing clearance. To do this, the flywheel must be moved in different directions. If there is a gap, then the bearings must be replaced.
  
  Other malfunctions are possible, which you can solve with your own hands. For example, the saw does not pick up speed or the chain is not lubricated. The first problem is related to improper carburetor adjustment, and the second is due to clogged hoses or insufficient oil in the fuel mixture.
  
  Chainsaw carburetor adjustment is carried out in order to set the optimal number of revolutions for efficient tool operation. It is done by adjusting the three main bolts:
  - L - is responsible for setting the low speed;
  - H - top speed;
  - T - idle setting.
  Some models have only one screw, the last one.
  
  You can adjust the chainsaw only with the first two bolts. If the number of revolutions needs to be reduced, then they are turned clockwise, if increased - counterclockwise. In this case, first turn the first bolt (L) and then the second (H).
  
  Additionally, you need to set the ignition. This work is carried out in the event that the saw does not start or began to work intermittently. To do this, you need to either replace the spark plug or fix the wire break.
  
  Also, the reason may lie in the incorrectly set ignition angle.
  
  This problem leads to the fact that the spark appears either before the fuel is supplied, or after a long interval thereafter. The required parameter can be found in the instruction manual for the chainsaw. Setting the ignition angle will help solve the problem.
  
  Not all chainsaw malfunctions are associated with a breakdown of the carburetor or its incorrect adjustment. In this case, you will have to repair the Partner chainsaw with your own hands, which is easy to do if you have a tool.This work is carried out in several stages, which depends on the cause and nature of the breakdown:
  1. Fuel system problems. This is most often due to a dirty fuel filter or breather. In the first case, it is necessary to remove the fuel hose and clean it. It must be rinsed and dried thoroughly before reinstalling. As a preventive measure, it is recommended to change the fuel filter every three months. Additionally, it may be necessary to clean the breather, for which it is convenient to use a needle or thin wire. The air damper is cleaned in the same way.
  2. Chainsaw carburetor repair Partner. Adjustment does not always lead to the desired result. The cause may be a clogged channel. Compressed air can be used to clear the blockage. It must be remembered that reassembly is only allowed if the parts are clean and dry.
  3. Cleaning the muffler. If you need to repair the chainsaw when the tool starts to stall at high speeds, you will have to disassemble and clean the muffler. To do this, the part must be removed, unscrewed all the bolts and disassembled. After that, using simple detergents, remove carbon deposits from all surfaces, and then dry thoroughly, you can use a hair dryer. In no case should the carbon deposits be removed dry, as it contains substances hazardous to health, which should not be inhaled.
  More complex problems are also possible, for example, wear of the piston and crank mechanism, which cannot be eliminated on our own. Therefore, sometimes you will have to turn to specialists for help.
  
  The chainsaw can only be repaired after the tool has been disassembled. It must be done with the utmost care, while it is recommended to clean each part with a detergent and dry thoroughly. Only then is the assembly of the tool allowed.
  
  To access the chainsaw sprocket, you need:
  1. Remove the crankcase cover, chain set and bar and then the air filter.
  2. Unscrew the spark plug and insert the piston stopper instead.
  3. Unscrew the clutch after inserting a puller into the Allen key hole. This will allow access to the sprocket, after which the last one can be removed.
