Replacement on the fuel tackle on a chainsaw. Why the gasopyle carburetor is called membrane

Installation of a primer on a Chinese chainsaw with your own hands

In this article, I wrote as the owner of the saw independently changed the carburetor and at the same time primer. When I conducted an inspection of the chainsaws, I immediately noticed that the primer was not set correctly and it was precisely what I decided to tell you, maybe someone will be useful to someone.

Primer is a manual fuel pump. Designed to download fuel into a carburetor.

In principle, the system can work without it, but the pump slightly accelerates the cold launch of the chainsaw, which means reduces the load on the starter. In general, the thing is useful and if someone doubts to buy a saw with or without a primer, I advise you to take with a primer.

How to install it correctly

The design of the primer has two outputs for connecting hoses from the chainsaw. precisely, one of them is the entrance, and the second exit. The entrance must be connected to the carburetor. Access to the opposite hose going to the tank.

At the time of pressing to the primer, fuel is squeezed out of it into the tank, then the valve at the output closes and due to the discharge in the primer, through the input pipe, fuel extends to the carburetor.

As a rule, the output pipe has a large length, the input smaller. Connection is better to start with the input pipe, this makes it possible to check the performance of the primer, at least I do just like that.

By connecting the primer to the input pipe going from the carburetor, you can put it on it several times, until gasoline starts to come from the output pipe. This is what suggests that the primer is set correctly.

How to install a primer on a chainsaw correctly

To date, almost every household has a chainsaw, which is a worthy replacement of axes and manual saws. The ideal solution for people living in a private house, or engaged in construction, will be the manual chainsaw “Partner 350”.

This instrument of the Swedish manufacturer is very convenient and compact, so it is suitable for any work on a personal plot. However, improper care and intensive operation of the unit can lead to its breakdown. At the same time, it is not necessary to immediately contact the service workshop. Many malfunctions can be eliminated with your own hands.

To do this, just study the saw device and video instructions for repairing it.

How to get a Chinese chainsaw with a primer. Practical tips

Chinese chainsaws with primer are widespread in the post-Soviet space. Chinese chainsaws with a primer are willingly buying because of their not high price. At the same time, Chinese chainsaws with primer cope well with the tasks when they are used for household purposes.

Very often, buying a Chinese chainsaw with a primer, the owner of the Chinese chainsaw is small experience in operating chainsaws.

Quite often, a completely serviceable Chinese chainsaw with a primer is sent to the owner for repairs, for the reason that he does not know how to start a Chinese chainsaw with a primer in a particular situation or another. Literally.

Brings the owner of the Chinese chainsaw with a primer to repair it and I have to show how to get it! This video was created to help the owners of Chinese chainsaws with primer. over, the shown practical tips are suitable for chainsaws with a primer of any other manufacturer.

Design features of the Partner 350 chainsaw

A reliable and convenient to use saw of this model has a gasoline engine with a power of 1300 watts. It is characterized by a light launch, which is carried out due to the built.in professional fuel pump and the electronic ignition system.

The chainsaw is equipped with a protection system, which automatically activates the double inertial chain brake. The lubrication of the chain also occurs automatically. It is very easy to change the tension of the chain of this unit with the help of only two keys.

The chainsaw is equipped with a fuel primer, so it easily starts at any time of the year. The instrument starter drum is equipped with a special impeller with which it is cleaned of pollution.

The CCS filter is able to detain all residual particles. In addition, such a system allows you to use an air filter for a long time, while saving fuel consumption.

Equipped the walls of the piston group cylinder with a chrome coating, which significantly increases the life of the instrument.

The main malfunctions of the chainsaw “Partner 350”

Most often, the reason for the breakdown of the tool is associated with interruptions in the operation of the engine or other nodes and systems. To eliminate any malfunctions, disassembly is required. To do everything right, you need to know the design features of the chainsaw and the main reasons for its breakdown.

Check the ignition system

First of all, with a malfunction of any chainsaw, you should examine the spark plug. For this, the wire is first disconnected, and then with the help of a special key the candle itself is turned out. In its appearance, you can understand the reason for the problem:

• The candle of the chainsaw coated with a soil indicates the use of low.quality oil, the incorrect ratio of oil and gasoline in the preparation of fuel or a poorly adjusted carburetor. In this case, the candle must be cleaned of soot with a needle or awl, wash and wipe the electrodes with a skin.
• If the candle is strongly sprayed with fuel, then most likely the carburetor is incorrectly adjusted or the rules for launching the tool were violated. To remove excess fuel, it is necessary to block the fuel supply, turn on the starter and check the combustion chamber. After that, the candle is wiped, twisted into place, and the mechanism starts again.
• A completely dry candle indicates that the fuel mixture does not get into the chainsaw cylinder. In this case, the cause of the breakdown is not in the ignition system, so the candle is placed back.

To check the efficiency of the spark plug, you need to put on the ignition cable on it, connect the cylinder and a candle nut with pliers, and start a starter. If there is no spark, then the candle must be replaced.

Repairs of the fuel system of the chainsaw

There may be several reasons why the fuel-air mixture does not fall into the cylinder:

• clogging of the fuel filter;
• clogging of the hole in the lid of the fuel tank (sapuna);
• insufficient amount of fuel;
• incorrectly adjusted carburetor;
• clogging of channels or violation of the integrity of the carburetor membrane.

Where is the bench on the chainsaw?

Chainsaw. a device that is useful for every owner. No matter what model you have a chainsaw, sooner or later you have to thoroughly study it in order to diagnose problems, repair the device yourself. Why is it necessary?

Of course, such a working tool is not safe from breakdowns, but some are not so serious that you contact the service center (where you have to leave a tidy sum). Sometimes a chainsaw may fail due. Do not know where the benzopile’s saapun is located? You will learn about this and much more from this article.

What is a sapun?

This is a part that looks like a standard valve. He plays an important role. normalizes the pressure in the tank of the chainsaw. Why is it important to normalize pressure? In order to answer this question, you need to consider the process of vacuum formation in the tank. This happens when, with airtight closing of the gas tank, fuel is supplied (while the pressure on the walls grows). The saapun evens out the pressure (in relation to the atmospheric). Without this small valve, the importance of which many underestimate, the serviceable work of the chainsaw is impossible.

Husqvarna chainsaw owners can also get acquainted with the leadership. how to clean the carburetor correctly?

Husqvarna 137 chainsaw. Replacing the clutch drum

The clutch drum of the chainsaw. One of the most common consumables on the chainsaw, because it is it that sets the cutting chain. The drums themselves are divided into two types. With a welded drive asterisk and with a variable crown, and in the second case only a variable crown wears out, the drum itself changes much less often.

During the repair of the clutch of the chainsaws, they adhere to the rules. When two chains are completely worn out, the tire changes when two tires wear out, the clutch drum changes. The level of wear of the sprocket can be determined without special devices, just inspect it. The chain, moving at high speed, at the end wipes the teeth on which it moves. If wear is strong enough, then replacement Clutch drum

The article will discuss the chainsaw of Husqvarna 137 replacement of the clutch drum. This is a simple procedure and occurs in several stages.

• First you need to remove the tire cover and the brakes of the quapi. For this, a combined wrench included in the chainsaws is suitable.

Then remove the air filter lid, unscrew the spark plug and fix the Husqvarna 137 chainsaw piston. For this procedure, it is recommended to use a conventional rope, since when using a metal plug there is a risk of breaking through the piston.

Filter

“Rich” or “poor” fuel mixture sooner or later will cause breakdown. Perhaps even expensive. To prevent this from happening, it will be useful to regularly check the filter for the presence of scuffs, as well as to break through the filtering canvas itself.

In most cases, the following problems are found in the engine:

• the engine stopped starting;
• The engine starts, but after some time stalls;
• The engine is not able to develop the necessary power;
• The engine works extremely unstable.

Malfunctions of the Chinese chainsaw: review of popular and ways to solve them

The most popular malfunctions of Chinese chainsaws should be attributed:

• Poor lubrication system. Clogged oil channels are cleaned, and if the oil pump is out of order, then replacement is necessary.
• The starter cable is torn.
• Basement of the plastic axis of the starter. An ordinary metal bolt is suitable for replacing it.

In the case of the slightest suspicion of incorrect operation of the chainsaw, it is worth immediately making a complete diagnosis of the tool. Only with proper operation and timely maintenance can one count on a long time for using the chainsaw.

How to clean an air filter

With non.receipt, a sufficient amount of air, the fuel mixture becomes too enriched, which leads to a violation of the normal operation of the engine. Regular purge of the air filter, and in particularly advanced cases, washing in soapy solution will avoid such problems.

Please note that flushing in acetone, gasoline or other aggressive solutions is not allowed. This can lead to a violation of the integrity of the filter element.

Why the chainsaw is smoking

Most often, excess smoke appears with excessive adding oil to the fuel mixture, which does not have time to burn to the end. You should also check whether the carburetor settings are lost.

The primer of the swimming fuel for Chinese chainsaws with a 25-52cm3 engine volume, Partner S-Series, Maxcut, SHAMPION (Benzoritm)

The principle of operation of the engine used in a modern chainsaw involves the combustion of a pre.prepared combustible formation consisting of a mixture of air, oil and gasoline.

In order for the mixture to enter a given proportion in the combustion chamber, the device needs a special mechanism called a carburetor. Adjusting the gasopyle carburetor ensures the optimal composition of the combustible mixture and the required power transmitted from the working shaft to the cutting canvas.

Description

Patriot RT chainsaw (Patriot Pt) 3816 is a popular chainsaw model for domestic use. The saw is ideal for use in a summer cottage, in the garden, as well as for sawing logs of medium and small diameter, harvesting wood and firewood for the winter. Patriot Pt 3816 chainsaw

The Patriot PT 3816 chainsaw is equipped with a gasoline two.stroke engine, a single cylinder, a capacity of 1,500 watts (2 horsepower). The volume of the engine cylinder is 38 cubic meters.cm, volume of the tank for the fuel mixture. 310 ml, the volume of the tank and chain lubrication. 210 ml. One dressing of the Patriot chainsaw is enough for 30-40 minutes of continuous operation.

The main advantages of this Patriot model are as follows:

• anti.vibration system;
• balanced center of gravity;
• quick access to the spark plug, air filter;
• automatic lubrication of the chain;
• practical and convenient for domestic use due to low weight.

Float carburetors

The principle of operation of membrane and float carburetors is the same. The difference is that in old carburetors, a float was used instead of a membrane. This is a sealed light container of copper alloy with a steel axis in the center. The lower part of the axis enters the sleeve at the bottom of the camera and serves to hold the float. Upper one is made in the form of a needle.

The photo shows a disassembled float.type carburetor, a friendship chainsaw, in the middle (in the form of a rocker of two barrels) is a float.

When filling the camera, the float pops up, the needle overlaps the supply of fuel, as in the membrane version. But if the chainsaw with a float carburetor is put to one side, the float will not be able to surfed to the end and the needle will not block the supply of fuel. The carburetor will begin to “pour”, as a result, the engine will stop working normally. Candle bay is possible when the spark disappears and the engine stalls finally.

On the old Friendship and Ural chainsaws, this lack of float carburetors was compensated by the design features of the chainsaw itself.

Unlike modern chainsaws, the position of the cutting headset was regulated in old models. The engine itself could remain in a stable position, vertically (a candle above), and the tire with a chain could be turned horizontally for a tree rally or vertically for sawing a lying trunk.

We recommend that a more detailed analysis of the device of float carbs be read in our article about carburetors of chainsaw Friendship.

In more detail, the device and the principle of operation of the float carburetor are disassembled in our article on the carburetor of the chainsaw Friendship 4.

Nevertheless, the operating position of the chainsaw with a float carburetor is always limited, which reduces the possibilities during operation. A chainsaw with a membrane carburetor can operate in any position, even turned upside down, which is important when sawing the bitches at the height and working in hard.to.reach places.

The reliability of both options depends on the quality of the materials used and assembly. The membrane should be made of plastic, resistant to gasoline and retaining elasticity for a long time.

The floats were out of order due to a loss of tightness and oxides in the channel, when the needle began to get stuck in it.

The membrane carburetor is suitable for chainsaws in the best way. The very principle of operation remains unchanged for more than half a century, but the quality of these devices is constantly improving. They become easier, more compact, form a better fuel mixture. As a result, ICE of the chainsaws with modern carburetors consume less fuel and throw less harmful exhaust gases into the atmosphere.

Proper operation of the chainsaw!

In our article we will tell you what a person should know when using a chainsaw. In addition, we will tell you why he should know this.

Chainsaw is a dangerous tool, it needs to be used extremely neatly. Before the first launch, carefully read the operating instructions.

Cleaning the chainsaw

It is necessary to clean the saw every time after work under the chain wheel cover from sawdust with butter, as well as wipe the inner surface of the lid. Otherwise, sawdust can be compressed and it will be difficult to tear them out of there.

Replacing chains, stars and tires

For uniform wear of the sprocket and tire chain, we recommend that you have two chains in stock. With proper handling, the asterisk is designed to work with two chains, after which it is necessary to replace the asterisk and both chains.

When working, the chain forms a production on the leading star, which is why the step on the asterisk increases, and therefore the chain is gradually stretched to a step that is real on the asterisk. If you put a completely new chain on an old star, the chain is stretched out with a jump, which is why it can even break.

Simple rule: 4 = 2 = 1. on average, two stars and four chains account for one tire.

The correct tension of the chain

You should not in any case allow sagging the chain. To check if you have pulled the chain, twist it with your hand in a glove or napkin. With proper tension, the chain will move with a slight effort.

If during operation you noticed that the chain was sagged (in case of heating), stop the chainsaw and tighten the chain. After work, be sure to weaken the tension! The chain will begin to cool and pull on the tire, if it is too tight, it can tear.

Correct handling of a saw tire

For uniform wear of the tire, it is necessary to turn it over, as well as change the chains (provided that there are 2 chains!).

Air filter

The air filter cannot be washed in gasoline or acetone, as this can lead to its violation of the integrity. The filter must be cleaned if the loss of power has become noticeable during the operation of the saw. When damage appears on it, it should be replaced. Therefore, it makes sense to purchase an additional air filter in reserve when buying a chainsaw.

Freeding saw

It is best to use the original oil for your chainsaw. It is designed specifically for use by tools of its brand and will not bring any damage to the internal nodes. Its use is absolutely safe.

The oil tank should not be completely devastated, since this can adversely affect the tire and chain.

Fuel

We draw your attention to the fact that gasoline or already mixed fuel should not be stored in an unintentionally recognized plastic container! Fuel can be stored in special fuel canister (for example, Khuskvarna has special canists: a greenhouse for gasoline, 6 liters, a canister for gasoline, an orange, a combined canister). Gasoline is an aggressive environment, and if the plastic from which the container is made is not intended for its storage, then gasoline begins to corrode it. The smallest particles of dissolved plastic are passed through the fuel filter and fall into the carburetor, clogging nozzles. The carburetor, which is closed with plastic, is not subject to repair.

The diluted fuel mixture can be stored for no more than a month (3 months are indicated in the instructions for your saw, but this corresponds to the European quality of gasoline). As practice shows. 1 month. the optimal shelf life for domestic gasoline in the absence of direct sunlight on a container with fuel and temperature difference.

Before prolonged storage of the chainsaws, the fuel must be drained and the tool is idle to burn the remaining fuel in the tank.

Why should this be done?

During storage, gasoline evaporates from the carburetor, and oil remains in it. The membrane, which in the carburetor is responsible for pumping fuel, sticks out, which leads to the fact that the saw is difficult to get.

How to sharpen a saw chain?

In the event that you are going to sharpen the chain in the room, then click the tire in a vice (this does not hurt the bus). If you don’t have a vice, you can buy a clamp.

If the number of links on the chain is not divided into 4, then it is better to start sharpening the chain from two links in a row, otherwise you will have to count the sharpened teeth).

Choose a tooth that is bend from you. The holder must be installed at right angles to the bus. Risk 30 ° should be parallel to the bus. Make two or three movements from yourself a file. In this way, sharpen through one cutting tooth, then turn the saw and sharpen the second part. For uniform wear of the file, do not forget to periodically rotate it and clean it from shavings. The power of the chain and the diameter of the suitable file are indicated on the sovereign. Do not forget to ensure that the notch of the file does not stop on the mounts, otherwise it will simply grind them.

Do not let the saw work at incomplete speeds or idle! You should not work on a half.gas or hazard!

The fact is that when working at incomplete speeds or idling, the fuel mixture is not fully consumed, on rings, piston, exhaust window, coke is formed. Когда кокса на выхлопе станет очень много, его кусочек откалывается и падает в поршневую группу.

• Do not use plastic fuel storage containers!
• Do not leave the equipment to work at idle speeds!
• Work only at full speed!

What type of carburetor is used in modern chainsaws

All modern chainsaws use membrane carburators. They were developed by German designers of the leading world manufacturer of the Stihl chainsaw in the mid-50s of the last century and revolutionized the construction of chainsaws.

Prior to this, float carburetors were used, which could only work when the chainsaw was in an upright position or under an angle of not more than 45-50 degrees. New membrane devices allowed to work with a chainsaw even in an inverted position.

Membrane carburetor from different angles.

How to get a Chinese chainsaw with a primer. Practical tips. Benzopila2019.ru

Turn out the candle, splash gasoline (cap from lemonade). If you start, then the carburetor is cleaned if it does not start. Added after 16 seconds:

The following actions necessary, in order to start a chainsaw, take in the indicated order, starting to take action under the next number only if the previous one did not help.

1) try to start just leave the chainsaw at rest for 5-10 minutes. Perhaps during the factory she got a candle. this happens. Then try to get it according to the instructions again.

2) Remove the case cover on the chainsaw, remove the air filter and try to start without it. If the filter is contaminated, then it should be washed in soapy water and dried or replaced with a new.

3) unscrew the spark plug from the chainsaw. Check the presence of a spark. If there is no spark, then try to put a new candle.

If the spark never appeared, then this means that the ignition unit is damaged and the saw must be carried for repair. True, the visual observation of the spark does not mean that the ignition unit is working.

If there is a spark, but the chainsaw did not work out, do the following on the list of action.

4) If the electrodes are wet, then turn the chainsaw to drain excess gasoline from the cylinder if it accumulated there. Tighten 10-15 times a starter without a candle to ventilate the combustion chamber. Procate the candle and twist it back, or better change it to a new one, if there is. Try to start again according to the instructions.

5) If the candle is dry, then pick up one or two cubes of the gas mixture in the syringe and pour it into the cylinder. Try to have a chainsaw. maybe a small snorinka got into the carburetor, which prevents the fuel from getting into the combustion chamber. This synchill will quite possibly eliminate the stream formed after the launch of the chainsaw by adding fuel directly to the cylinder.

6) unscrew the silencer and remove it, trying not to spoil the gasket between the silencer and the engine. Try to get without a silencer and air filter. With the muffler removed from the chainsaw, you can inspect the piston from the inside.

If there are burrs or bullying on the walls of the cylinder or piston, or the ring on the piston is clamped with burrs, then it will have to be very upset, as this means that the piston is damaged or worn out. This usually happens with underfilling in the fuel mixture of oil.

With such a malfunction, you will have to contact the service, and it is possible to think about buying a new chainsaw, since replacing a piston is a fairly expensive operation.

Installation of a primer on a Chinese chainsaw with your own hands

I would like to install a pepper primer on a chainsaw, how to connect it correctly to the fuel system, so that it helps when starting.

In my opinion, this is a delusional idea. If a primer is not provided on the saw, then a system is provided for a lightweight launch. For example, at the Urals 2t saw, it is enough to close the air damper, and handle the engine several times.

So he gets around. But there is a primer. And if you really want to, I would advise between a tank with gasoline and a carburetor to install a hose from a system with a filrix. The filter will play two roles, cleanse and can be used as a pear of swings.

Gasoline saws are used in the construction of log cabins, logging, cleaning the area from thickets, replenishing the stock of firewood. They allows you to effectively perform work with wood. A relatively simple chainsaw device makes it a durable and reliable tool for both domestic use and professional activities.

Structurally, the product belongs to the category of machines equipped with an internal combustion engine (ICE). In many cases, it is a two.stroke single.cylinder motor.

Knowing the device of the tool and the features of the functioning of its individual nodes need to the user. this will help to correctly perform maintenance and, if necessary, independently repair.

Can a saw work without a primer cap

Chainsaw. this is not such a complicated device. But for which the design of detecting a malfunction is intended to have at least basic knowledge in order to find and remove the lack.

It is necessary to consider the main malfunctions of the chainsaws, we will find out what they are connected with, we will also analyze the main steps to correct the breakdowns.

And most importantly, while proceeding to repair, this is the correct definition of a malfunction. And the circumstances of the inoperability of each element and possibly several. Therefore, before starting disassembling the chainsaw, you must try to find what the refusal is related to the work.

You, the refusal during the operation of the chainsaws can be caused by a malfunction of the motor by another appearance of breakdowns in its other nodes.

• ignition malfunction;
• problems in the fuel supply system;
• Piston malfunctions as it is also called the cylinder.

• In other nodes, in most cases, malfunctions appear due to failures of the brake mechanism, lubrication system
• , Clutch clutch, tires, etc.
• It is necessary to consider both groups of defects so that you can if it is necessary to find the cause of the breakdown on your own without turning into a repair workshop.

Engine malfunctions

During the operation of the motor, in most cases, subsequent shortcomings are observed:

In order to find the cause of the problem, it is necessary to analyze the likely prerequisites all in order to exclude. Let’s go through this chain so that you know how to find a flaw in a chainsaw for which the design of its occurrence is intended.

How to install it correctly

The design of the primer has two outputs for connecting hoses from the chainsaw. precisely, one of them is the entrance, and the second exit. The entrance must be connected to the carburetor. Access to the opposite hose going to the tank.

At the time of pressing to the primer, fuel is squeezed out of it into the tank, then the valve at the output closes and due to the discharge in the primer, through the input pipe, fuel extends to the carburetor.

As a rule, the output pipe has a large length, the input smaller. Connection is better to start with the input pipe, this makes it possible to check the performance of the primer, at least I do just like that.

Installation of a primer on a Chinese chainsaw with your own hands

The low level of technical equipment of many service services and the high cost of their services forces many owners of faulty chainsaw equipment to repair their gadgets on their own. How to disassemble a chainsaw, replace faulty parts, and also correctly collect a chainsaw with minimal time and means?

Independent disassembly of a chainsaw suggests the presence of spare parts, the corresponding tool and locksmith skills. It is possible that for the dismantling of individual parts you will need special pullers, the manufacture of which will take more time than the repair itself.

In a number of modern models of household and semi.professional chainsaws, to adjust the carburetor and dismantling the drive sprocket of the saw chain, special keys that are not included in the attached kit are used in the attached kit.

Problems of independent repair

The problem in many cases is complicated by the lack of full.fledged information on repair technology. According to foreign manufacturers, after the development of the saw, the saw should be written off in the scrap, so the maintainability of many budget level models causes reasonable doubts.

They are more difficult to restore a professional class chainsaw.

• The problem is complicated by the high cost of spare parts.
• It is possible that to restore the performance of individual nodes and mechanisms, in particular, special equipment will be required to set up fuel equipment.

Replacing expensive branded parts affordable in cost, but in short.lived Chinese analogues in economically does not justify itself. Practice shows that these components produce a resource at best by 50-60%.

The algorithm for determining the malfunction

The reason for the refusal of the saw or the deterioration of its performance may be:

• a clogged battleship cover;
• Air sucker with a carburetor due to the destruction of the gasket or weakening of threaded fasteners;
• Mechanical sequel of removable saw equipment and other minor defects.

Before starting disassembly, you should verify the need for a more volumetric repair.

Independently assemble a new chainsaw after repair with initial quality, most likely it will not be possible. In the design of modern chainsaws, press plantings of conjugated parts are often used, which have minimal maintainability.

Even a partial analysis of a chainsaw with an improvised tool can lead to undesirable consequences. In most cases, to eliminate a malfunction, you can limit yourself to the dismantling of a separate node or system.

The design and principle of operation of the chainsaw nodes

Gasoline saws are used in the construction of log cabins, logging, cleaning the area from thickets, replenishing the stock of firewood. They allows you to effectively perform work with wood. A relatively simple chainsaw device makes it a durable and reliable tool for both domestic use and professional activities.

Structurally, the product belongs to the category of machines equipped with an internal combustion engine (ICE). In many cases, it is a two.stroke single.cylinder motor.

Knowing the device of the tool and the features of the functioning of its individual nodes need to the user. this will help to correctly perform maintenance and, if necessary, independently repair.

Tips for the dismantling of different nodes and systems

Only general recommendations can be given in the volume of this article, since chainsaws from different manufacturers may have significant technical differences.

Before disassembling a faulty tool, it is necessary to dismantle the saw headset, drain fuel and oil from gas tanks, clean the inaccessible places of the chainsaws from surface pollution.

Compression restoration

Less complex repair of the piston group. To dismantle the cylinder, it is enough to remove the threaded fasteners, lay the saw to the side to eliminate the slices of the destroyed compression ring, the piston skirt or other extraneous objects to get into the crankcase of the engine.

The cylinder mirror wears out unevenly, so the installation of a new piston does not give a significant effect. As a rule, during major repairs, after checking the suitability of the crankshaft, a full set consisting of a cylinder, a piston of a compression ring and a piston finger is installed.

Repair of the starting device

Dismantions of the starter for replacing the cord for an experienced user do not create problems, but the plastic case in most cases is not subject to repair. The Chinese chainsaw assortment for the most part is copies of the most popular European models, so we analyze the Chinese chainsaw according to the standard scheme.

Worn details of the saw headset are not restored.

• At home, you can shorten a new chain for installation on a shorter tire.
• The resource of branded components of tires is equal to the resources of three saw chains.
• This indicator can be significantly reduced by the wrong choice of chain step or a large wear of the crown of the drive star.

STRACTION adjustment

The circuit brake often does not work due to clogging with lubrication or sawdust of the brake tape and space under the lid. All parts from blockages should be cleaned. Perhaps the tape simply worn out, then it must be replaced.

The operation of the brake of the backup is restored using mechanical cleaning

Some parts of the chainsaw wear out faster than the rest. These include the leading star, tire, chain, anti.vibration elements. It is better to always have at hand for quick spare replacement at hand. Do not neglect the sharpening of the chain.

Tire, circuit, chain brake and lubricant

After the wear of the two chains, the leading star is required to replace the leading. The use of a worn star affects the resource of the crankshaft bearings and is expressed in strong vibration, the chain also spoils faster. The chine is recommended to turn over the working part.

The reason for the poor operation of the brake may be abundant pollution of the space under the lid or the overall wear of the strip spring. Cases are also frequent when when the brake is triggered, the adhesion is destroyed from overheating and the entire node needs to be changed.

The lack of lubrication on the chain can cause clogging of the oil pump channels, it must be washed in gasoline and cleaned with fishing line. If the oil comes too hard when working, you need to tighten the oil pump adjustment screw slightly. It happens that when working, the chain is dry, and with simple oil oozes under the clutch. This means that the tightness of the oil hose is disturbed and it must be replaced.
