Cleaning fuel filter Echo chainsaw filter. Cleaning the fuel filter of the chainsaw

How to clean the fuel filter on a chainsaw

All malfunctions of the chainsaws can be divided into two main groups: engine problems with all its nodes and systems (ignition, fuel supply system, cylinder-piston group, exhaust system) and malfunctions of other nodes (circuit brake, lubrication system, clutch, tire, etc.).

Engine malfunctions

The engine will not start;
starts, but stalls;
It works unstable;
does not develop power, t.e. It works normally at idle, but stalls under load.

When repairing the chainsaws with your own hands, you need to act by exclusion. check all possible causes of the malfunction alternately, starting with those, the verification and elimination of which takes less time (about the device and operation of a two.stroke engine, see here).

Almost all types of engine malfunctions listed above may be called the ignition system failures. Therefore, when they occur, it makes sense to start searching for a malfunction from the candle. This is all the more justified that the state of the latter can give useful information about the operation of the fuel system. So, when a problem occurs, you need to turn out the candle and inspect it.

The wire is disconnected, and the candle is twisted with a special key.

If the candle is dry, this means that the problem is most likely not in the ignition system, but not admission to the fuel mixture cylinder. You can wrap the candle back and take for the fuel system. If the candle is strongly sprayed with the fuel mixture, then there is its excess. This can happen from the dilution of the carburetor or violation of the launch rules. The candle is wiped and dried, the cylinder is drained, blocked by the fuel supply and working with a starter. to exert a combustion chamber and remove excess fuel. Then set the candle in place and repeat the launch.

The presence of a large amount of black carrier also indicates malfunctions in the fuel system.

The ratio between oil and gasoline in the mixture may be disturbed, the carburetor is not adjusted or poor.quality oil is used. The candle is washed in gasoline, cleaned with a needle or an awl from the carbon, clean the electrodes with a small skin and installed in place.

In all these cases, it will not be superfluous to check the gap between the electrodes of the candle. Depending on its brand, it should be in the interval of 0.5-0.65 mm. You need to check the sealing of the candle. With its worn out or damage, the tightness of the combustion chamber may not be ensured, which leads to a decrease in compression in the cylinder and problems in the engine operation.

Even if in the case of checking the candle there is large reasons to believe that the malfunction is in the fuel system, you need to check the candle for the presence of a spark. At least in order to be sure that everything is in order with this. For this:

put on the spark plug on the candle;
Using pliers with insulated handles, apply a thread or a candle nut to the cylinder;
pull the header’s handle and look. there is a spark or it is not.

In the absence of a spark, you just need to replace the candle. If the new candle does not have a spark, you need to check the condition of the high.voltage wire for the presence of a cliff and contact with the candle.

The reason for the lack of a spark can be a faulty ignition module or a disruption of the gap between it and the magneto pipeline of the flywheel. It should be equal to 0.2 mm. The disruption of the gap becomes especially probable if before this was the disassembly of the saw from the filming of the flywheel and the ignition module. The gap is exhibited with a gasket with a thickness of 0.2 mm placed between the boss of the flywheel and the ignition module. Failed ignition module should be replaced.

By checking the ignition system in this way and without finding a malfunction, you can proceed to the fuel mixture supply system.

If the candle with a candle was established that the fuel does not enter the cylinder, you need to consider all the possible causes of this. It can be:

not the intake of the fuel from the tank due to the clogged hole in its lid (sapuna), while a vacuum is created in the tank that prevents fuel flow;
pollution of the fuel filter installed in the tank;
non.admission or insufficient intake of the fuel mixture from the carburetor to the cylinder.

To diagnose the first two reasons, it is enough to disconnect the fuel hose from the carburetor and see if the fuel flows from it or not. If it flows with a full stream, the sappan and the filter can not be checked, if it does not flow or flows weakly, we can assume that the cause of the malfunction is found. The sapun is cleaned with a needle. The fuel filter is extracted through the flood hole of the emptied fuel tank, with a wire hook, along with the suction hose, from which the filter is disconnected and cleaned or replaced by a new. Mastery manufacturers recommend changing the fuel filter every 3 months.

Insufficient intake of the fuel mixture from the carburetor to the cylinder or a violation of the correct ratio between fuel and air mixed in the carburetor can occur for several reasons: due to the air filter, unexplored carburetor, clogging its channels or mesh-filter.

As a rule, the repair of the chainsaws is not complete without cleaning the air filter, since it is polluted quite quickly. When this happens, the flow of air into the carburetor decreases, the fuel mixture at the exit from it is too enriched, which violates the normal operation of the engine. Removing a dirty filter for cleaning must be carefully so that the dirt from it does not get into the carburetor. The filter should be cleaned or washed in water with some detergent, dried and installed back.

Carburetor’s resolution is eliminated by its adjustment. This is usually done using three screws. maximum and minimum revolutions and a blank screw. Adjustment should be carried out in strict accordance with the instructions, the non.compliance of which can lead to engine breakdown. Some saw manufacturers leave only one adjusting screw (idle turnover). to exclude the unwanted intervention of inexperienced users in the carburetor operation. An example of adjusting the chainsaw carburetor See in the article a chainsaw work.

How should the chainsaw be cleaned?

produced both in general and for its individual mechanisms. In the first case, the chainsaw housing and all its surfaces from the wood dust and other mud are cleaned and all its surfaces are cleaned. It is advisable to produce it regularly, immediately after the completion of the work performed.

But regular cleaning still does not cancel the need to clean its most important nodes and mechanisms, among which the filter, carburetor and muffler are the most vulnerable.

Based on the difficult conditions in which the chainsaws have to work, the filters for them are the most important element. They retain the engine lubrication in cleanliness, which means that they protect it from breakdowns.

Depending on the degree of pollution of the filter, it is cleaned by blowing or washing in soapy water. For the best purge, you should purchase a spacecraft with compressed air, designed to clean the carburetor. With this spray, you just blow out an air filter from its inner side. A stream of compressed air will not only free the filter mesh from dust and dirt, but also from moisture inside the cells.

Clean the filter from the chainsaws every time after completing work with it. And it doesn’t matter how much time you worked with her. at least half an hour, at least a few hours.

With strong pollution of the filter with any oily substances or dirt, it should be washed in soapy water. Instead of soap, you can take an ordinary dishes for washing, for example, the same Galu.

Carburetor cleaning. the procedure is more complicated than cleaning the filter. Often, owners recall the cleaning of this device only when the chainsaw refuses to work: after turning on, it immediately stalls. So, the carburetor is polluted until complete impossibility!

To clean it, the carburetor is extracted from the chainsaw housing and disassembled. After disassembly, you will most likely find that in the sump. a bunch of garbage, and the membranes are clogged with oily mud.

If the pollution is not so critical, then cleaning the carburetor can be made by blowing with compressed air. To clean the membranes from dirty oil, you can use the universal liquimol cleaner or take a veryylub cleaner from XADO. In principle, now there are many similar cleaners in stores, and therefore their specific name is not so important.

With very strong pollution, the cleaning procedure will be as follows:

With a hard brush, the place of installation of the carburetor is cleaned of dust and dirt, including the niche where it is inserted;
In the presence of an oily film on the surface of the carburetor and the chainsaw body, it is removed with a clean dry rag;
Membranes are cleaned by universal cleaners;
The carburetor is washed in soapy water to clean its inner surfaces from oil and dirt.

After all these procedures are performed, the carburetor is assembled and installed in its place.

The muffler cleaning is also an important procedure, on which it will directly depend on how comfortable it will work with the chainsaw. A carcass can form on this mechanism, the cause of which is a flooded low.quality engine oil or an incorrectly configured carburetor. Due to a very thick carbon fiber, a chainsaw may stall or not get started at all.

The method of cleaning the muffler from the carrier will depend on whether it is collapsible or not. In the first case, it is disconnected from the chainsaw and the carcass is cleaned with a hard brush, and then treated with fine sandpaper.

If your chainsaw is installed on your chainsaw, then it will be somewhat more difficult to clean it from the car. On the Internet you will find a lot of tips on how to perform this procedure from quite simple, for example, processing a muffler with acetone, to very exotic, for example, apply a small fraction for these purposes. But we recommend using special cleaning products.

Chainsaws are available on almost every resident of the village and many dacha owners. They are easy to use and they can be repaired with your own hands. Find out the reason why the devices is not started, troit, has problems with idle, not so difficult. Despite the varieties of chainsaws, the principles of repair are the same.

Household. These saws are used in everyday life. For example, for harvesting firewood, cut the boards. Household saw can be cut off branches and trees of small thickness. The tool has a minimum of functions, low power and weight up to 4 kg. Household saws are the cheapest and are not designed for a long job. Recommended use up to 20 hours a month, that is, 40 minutes a day. Women and elderly people can use such saws.
Semi.professional. They are used to carry out rolls of trees and construction work. They are often purchased for professional use, for example, employees of landscaping firms. But in everyday life, such saws can be used due to the size and weight smaller than that of a professional tool. Technical characteristics and price are between household saws and professional. The lack of these saws. you can not work for 10 hours continuously. You need to make big intervals.
Professional. Such saws have all the necessary functions, high power up to 6400 watts, large size and weight. They are used by utilities and rescue services, but they found the main use in lumberjacks. After all, such a powerful tool can be cut down trees with a diameter of more than 70 cm and work 8-10 hours without interruptions. Professional chainsaws have been serving for years. Have the most reliable piston system, chrome cylinders. Working resource 3 times more domestic models. Accordingly, the price of such a tool is the highest.

The purpose of the tool affects power, weight and size. The chainsaws have three purposes:

We clean correctly

To clean the chainsaw, the following tools will be required:

cross,
wrenches with heads of different sizes,
special cleaning composition, cleaning fabric,
Ultrasonic cleaner.

Tool set can be seen in the photo.

Carburetor cleaning the chainsaw should be done according to the following algorithm:

First you need to drain the remaining fuel from the fuel tank. Remove the chainsaw lid, unscrewing the fasteners. We take out the filter and disassemble the case by removing the nuts and the latches if necessary.
Remove the fuel mixture supply hose from its latch, unscrew the fasteners of the upper carburetor cover. Then we remove the top cover and blue gasket. this is a fuel pump membrane. Spring brackets are located to the left of the body, remove them, and then the screws. It is advisable to sign the details and schematically fix the places from which they were removed so as not to confuse anything at the time of assembly.
Remove the bottom cover of the carburetor, unscrew the screw and remove the needle valve and a spring under it. Then, with longitudinal force, remove the air damper and its axis.
Remove the throttle shutter, drive lever and throttle axis.
We lay out all the removed parts of the carburetor on a flat surface and conduct an inspection to maintain integrity. Parts with a high degree of wear must be replaced with new.
With the help of a specialized cleaner, wash the parts and dry with a smoker rag. Tubes must be blown under pressure using a pump.
To achieve the maximum effect, to clean the carburetor on the StiHL chainsaw using a special oarbic bath, which is based on the cavitation effect. The bath is filled with diesel fuel, the parts of the carburetor are plunged into it for a few minutes. At the end we dry the parts with the help of the pump.

A detailed video with the cleaning process will help to work correctly.

After all the products are dried, it is necessary to assemble the carburetor. Usually the detergent completely evaporates per day. It is better to wait a day after cleaning, since the remnants of detergents on the details can get into the fuel compartment, and when combustible they will release toxic gases.

Another important nuance associated with disassembling the chainsaw is that it is necessary to extremely accurately install and configure the needle valve petal, otherwise the chainsaw may not start. To check the correct installation of the petal, you can use the blade. Having installed it from above, we look at how much the petal rotates freely. If there are no problems, then everything is in order. you can continue the assembly. If the problems of the course still occur, then the petal must either be crushed or bend the edge on it.

How to clean a chainsaw filter

To clean the filter of the chainsaw of Husqvarna is necessary after each use. The process of cleaning itself, depending on how much the filter is contaminated, can be done in two ways:

The mechanical method of cleaning, which is a blowing of the filter.
With a higher degree of pollution, the filter is washed in soapy water.

Important! It is forbidden to rinse the filter in aggressive solutions: gasoline, diesel fuel, acetone.

How to clean a muffler on a chainsaw

Timely measures to clean the muffler of the chainsaw can seriously extend the life of the tool. There are several causes of muffler pollution:

To check the condition of the muffler, it is necessary to dismantle it and look inside. If you need to remove the silencer on the stihl chainsaw, you need to remove the muffler fastener, the muffler, the plate and the reflector itself.

If you find a carrier inside the silencer, then this problem is solved in two ways:

Mechanical method (cleaning is carried out using brushes, sandpaper and special tools). This path is possible if the muffler understands.
In the case of a non.devastated muffler, special cleaning compositions are used, in which the muffler is soaked for several hours.

Correctly performing all the actions, you can easily clean the chainsaw, extend the life of the tool and protect yourself during operation.

How to replace or clean the filters of the chainsaw

Classical gasoline chainsaw requires periodicly with the replacement or cleaning of air and fuel filters.

In the article we’ll talk about how to properly carry out flushing or replacing filter elements, as well as how often to do it.

All replacements and flushing are carried out exclusively with a stopped, cooled engine. Also, before the work, it is necessary to disconnect the light of the ignition so that the unexpected launch does not occur.

Washing the air filter of the chainsaw

In the instructions for any saw, the purification of the air filter element refers to the procedures carried out after each application.

Option filtering and installing the filter in place

How to rinse the chainsaw filter:

Unscrew the top cover. The desired compartment is located in the upper part of the case near the handle, regardless of the brand. be it Husqvarna, Sturm or Partner.
Remove the filter. it can be invested or screwed onto the screws.

Wash the foam filter with warm water and soap and dry in the air. When cleaning with gasoline, the filter service life is reduced.
Paper, mesh, felt. you can shake off slightly tapping the edge on a dense surface. They are also well cleaned/blown by a compressor or vacuum cleaner.

All the dirt in the space around the engine must be wiped.
Install the gas station air filter in place, make sure that all the grooves and parts are tightly in place. Close the lid and tighten the screws.

If the filter began to deform, became denser and thinner, holes and cuts appeared. it must be replaced.

Replacement of the fuel filter of the chainsaw

Like all the technique working on fuel. the chainsaws have a fuel filter, it is located in the fuel compartment.

The main symptom of the faulty fuel filter of the chainsaw is stalling when you press the gas.

How to change the filter is not a chainsaw:

When replacing the filter element, there is no need to drain the gasoline mixture.
Take a thick wire, bend the end. in the shape of the hook.
Unscrew the fuel tank cover.
Lower the hook into the tank and hook the pipe with the filter at the end. The tube is short enough, so when the filter is noted, do not pull hard, the length is enough only to replace.
With one hand, hold the tube, pull the filter with the other and remove it from the port. insert a new one.
Make sure the filter has entered the port tightly. Lower the filter pipe into the tank. At the engine factory, the filter itself will fall into the right position at the bottom.

How to clean the fuel filter of a chainsaw

If the filter looks fresh enough, you can do without replacement and rinse it with gasoline. The element is removed and installed back according to the described scheme.

How often they change the fuel filter of the chainsaw:

The average frequency of replacement every two years, washing helps a little extend the service life.
With heavy operation. a new filter element will be required earlier. A sure sign of the need to replace. after washing, little time has passed and drank again.

How to rinse the fuel filter of a chainsaw?

Chainsaw. this is not such a complicated device. But in case of detection of a malfunction, you need to have at least basic knowledge in order to find and remove the lack.

Let’s see the main malfunctions of the chainsaws, find out what they are connected with, we will also analyze the main steps to correct breakdowns.

Most importantly, before proceeding with the repair, this is the correct determination of the malfunction. And the circumstances of the inoperability of each element can be several. Therefore, before starting disassembling the chainsaw, you must try to find what the refusal is related to.

Usually, the refusal of the chainsaws is caused by a malfunction of the motor or the appearance of breakdowns in its other nodes.

In other nodes, in most cases, malfunctions appear due to failures of the inhibitory mechanism, lubrication system, clutch coupling, tires, etc.

Let’s see both groups of defects so that you can, if necessary, find the cause of the breakdown on your own, without contacting the repair workshop.

Cleaning the carburetor of the chainsaw of any modification, configuration and power passes through one traditional and correct scheme, and its need arises as a result of clogging of the part. To understand that it is time to clean the carburetor. you can observe how the saw starts and immediately stalls, perhaps still “whirlpool”, publishing samples to get the desired turnover.

One way or another. to clean the carb with your own hands. it is quite real, because our experts presented instructions and demonstrated how to do it quickly and correctly.

Regarding the literacy of cleaning, here we are talking not only about the use of certain means, liquids, but also the format of purging, assembling the carburetor back, as well as checking its readiness for future work.

Sometimes spare parts for a chainsaw do not need repair and cleaning, but in timely replacement. Therefore, while your carb can still be cleaned and returned to the initial working condition. use the advice from the kosikos, and let your mechanism be healthy!

How to clean a carburetor on a chainsaw with your own hands

Before cleaning the carburetor on a chainsaw, we will deal with situations when it is needed to clean it:

There are situations that cleaning the carburetor does not help, then you need to replace the reprimatitis, if after this procedure nothing has changed. check the rubber adapter, which is between the cylinder and the carburetor (in its place there may be a rubber adapter with brass insert). Remove the top cover, filter, long bolts, adapter, turn off the tube from the carb and remove it. Directly cleaning process:

First, you need to clean with a fibrous brush from external dirt and dust so that it does not get into the inside during the analysis;
We start with the “h” bolt, which is responsible for the upper working position of the carburetor, at maximum speeds. We twist it, counting and remembering the number of revolutions, for example, 2.5. Then we twist it
We screw the screw “L” with the speed of revolution, it is responsible for low speeds. For example, 4.5 revolutions. Record the indicators and twist it;
Remove the upper and lower cover with a screwdriver, unscrewing the bolts. It is better to do this not a canopy, but on a hard non.penis;
we take out the needle;
If the gaskets and membranes are strongly worn out, the wiped out. they also need to be changed to new ones, and the carburetor reptile for the Husqvarna saws, the leader, STIHL or PARTner can be ordered in the Kosikos store;
Often, before cleaning, you can observe the following picture. in the “Slodnoye” and other containers. a lot of dust and garbage;
We clean the carb, after soaking in its solvent, then blow out the compressed air using the compressor. Repeat the procedure 2 times. Separately clean the membrane and collect back. First, put the needle in place;
We mount the rod back on the needle;
squeeze the spring and squeeze the fixing bolt;
put in place the membrane, the lower cover and twist with bolts (you need to remember or sign which it fixed it);
We also put the upper membrane with the lid in place and tighten with bolts;
We place the “L” screw until it stops, and then we unscrew 4.5 turns on its, (as an example) how it was on a carburetor, and we also screw the screw “H” to stop and twist it for the same 2.5 turns (as an example ), keeping the previous settings. This is necessary in order not to lose settings;
We return the carburetor to the back place in the chainsaw for checking, putting on the throttle;
The hose leaving the cylinder is hung on the top, the hose leaving the tank on the right side of the carburetor, and the hose that goes to pump from the primer. with the left. we connect all the hoses with the carb;
We insert 2 bolts into the adapter and put it in place;
Close the damper, press several times on the primer (enough10);
We try to start the tool.

As you can see, it is not difficult to clean the carburetor of your tool with your own hands, if you follow the instructions, chronology, fix the speeds of the screws maximum and minimum, collect the unit exactly in the opposite order. Kosikosa benzo.instrument store also shows high.quality video, where all the instructions brightly reinforces a visual example.

Carburetor cleaning and all about it: Useful tips

You are already oriented: what is the cleaning of the carburetor of the chainsaw. We have painted all the nuances and trifles, and now in the resume we will consider other options for breakdown or faulty tools of the tool, accompanying clogging of the carb, which also need to be paid attention to:

The failure of the rubber adapter. When it breaks through, the chainsaws gives the same non.working signs as with a clogged carburetor. It is located between the cylinder and the carb;
You can hear its name and as a pipe. The chrome of this that the carburetor is clogged in the saw, the pipe can rotate;
It will not be enough to clean the carb, you will have to change the rubber adapter. Our catalog will help to do this easily;
The fuel filter fixer can be cracked or broken, respectively, all the dirt enters the carburetor;
A crab grid can be clogged, which should clean gasoline, which passes from the tank to the needle;
Do not forget to fix the number of revolutions on which the screws “h” and “l” were twisted. Adhering to their competent return to your place. you will save the settings of the carburetor, but this is a completely different article.

How to clean the fuel filter of a lawn mower

When working with a tool such as a chainsaw, its owner often encounters a number of problems, one of which is clogging the carburetor. This can happen if the chainsaw is refueled by poor.quality gasoline or if foreign garbage got into the fuel tank. In order to clean the carburetor carburetor, you must first disassemble it.

A detailed video about the cleaning process will help you do the job right.

After all the products have dried up, the carburetor must be assembled. Usually the detergent completely evaporates in the day. After cleaning, it is best to wait for one day, since the remaining detergents on the parts can get into the fuel compartment, and toxic gases will be released when combustible.

Another important thing when dismantling the chainsaw is that you need to very carefully install and adjust the needle of the needle valve, otherwise the chainsaw may not start. You can use the blade to check that the petal is installed correctly. Having installed it from above, we see how the petal rotates freely. If there are no problems, then everything is fine. You can continue the assembly. If problems with the blow still arise, then the petal should be either crushed or curved on it.

How to clean a muffler on a chainsaw

Timely measures to clean the muffler of the chainsaw can seriously extend the life of the tool. There are several causes of muffler pollution:

If you find a carrier inside the silencer, then this problem is solved in two ways:

Mechanical method (cleaning is carried out using brushes, sandpaper and special tools). This path is possible if the muffler understands.
In the case of a non.devastated muffler, special cleaning compositions are used, in which the muffler is soaked for several hours.

Correctly performing all the actions, you can easily clean the chainsaw, extend the life of the tool and protect yourself during operation.

A chainsaw is a simple device that, with proper care, can last a long time. At the same time, the saw is a tool subject to various loads and, therefore, breakdowns are still found. About what caused a certain malfunction and how to eliminate it, you will learn from this article.

First stage

The adjusting screws of the highest and low revolutions should be closed clockwise until the moment of the highest resistance. When the screws reach the stop, you need to translate them in the opposite direction and leave them with 1.5 turnover.

Now remove the membrane. It is she who performs the function of pumping fuel to the carburetor.

With the vibration of the membrane, the other side exerts the pressure of the rocker of the mechanism and the needle rises, which, in turn, opens the hole and the fuel supply occurs.

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

The engine warms up, that is, it starts about 10 minutes before the repair, and turns off at the beginning of work (see. how to get a chainsaw).
Air filter is checked and washed.
The circuit stops by turning the screw t to the stop (see. Oil for the chain).

To carry out safe repair, you need to prepare an even surface, where you can carefully place the device, and turn the circuit in the opposite direction. Need a tachometer. It determines the presence of a violation in the carburetor. When revolutions, the sound should be perfect and absolutely even. If screaming notes are noticed, then the mixture is oversaturated.

DIY lawnies repair: analysis of malfunctions and methods for their elimination

The lawn mower is one of the main instruments of the summer resident used to quickly bring the land in order. The owners of private houses acquire this weapon for mowing grass in the personal territory. The period of active use of benzos and electric trimmers falls on the summer period. Before starting operation, the tool is brought into working condition: the rubbing parts are lubricated, the cutting headset changes, the fuel mixture is poured into the tank. If the engine does not start or stalls quickly, without gaining enough revolutions, then you have to look for the causes of problems and eliminate the identified malfunctions. To carry out the repair of the lawn mower with your own hands, you need to understand its device and the principle of operation of the main nodes. This information can be found in the operating instructions, which the manufacturer applies to garden equipment without fail. Check for such a manual when buying a chainsaw. The import tool should be accompanied by instructions written in Russian.

Typically, the process of replacing fishing line on a trimmer of a particular model is popularly described by accompanying documentation. Another question is that this documentation is often supplied in a foreign language, since the notorious lawn mowers for the most part are imported products.

Meanwhile, there is a much simpler, more economical and healthy way for human health and nature. putting the lawns of an ordinary peasant oblique in order. Blory of braids for grass:

which is subsequently accompanied by abundantly growing greens, and not by the formation of dryness as a result of the work of a trimmer for grass.

Where to look for a reason or where to start checking

All chainsaws have the same design, and work according to one principle. The device of the chainsaw can be found in this material. It does not play much meaning which brand of the tool. Stihl, Husqvarna, Echo, Champion, Partner, Sturm and others. A malfunction manifested in the form when a chainsaw is stalling when pressed on gas can arise the same both on expensive and high.quality tools and on budget Chinese devices. If the problem has arisen, then it needs to be solved.

A chainsaw is a system of mechanisms consisting of details. Any detail in the mechanism can fail, which will lead to a partial or complete failure of the tool. If the tool engine starts, then this does not mean that the chainsaw is completely serviceable. Когда при повышении оборотов происходит прекращение работы двигателя, значит на то имеются соответствующие причины. With this malfunction, you need to pay attention initially to a number of the following tool mechanisms:

Gas tank. make sure of the presence of fuel. If fuel is in sufficient quantity, you should also check the serviceability of the fuel filter, the presence of a connection of the supply hose with the carburetor, and also make sure that the operability

These are the main details and mechanisms that should be checked first if there is a malfunction when the chainsaw stalls when the accelerator is pressed. There are other reasons why the chainsaw engine stall when the gas trigger presses. What else can contribute to this malfunction, as well as features of elimination of breakdowns, we will find out later.

Carburetor adjustment when the engine stalls when recruiting

If the audit showed that the fuel supply system, the muffler and the spark plug are serviceable, then you need to look for a breakdown in other places. Do not rush to disassemble the cylinder-piston group or change the carburetor. It is recommended to start repair with carburetor adjustment. For this, all chainsaws have special adjusting screws. They are designed to configure the work of idle, as well as adjusting the supply of fuel at low and high speeds. A detailed description of how to regulate a chainsaw carburetor is described on the site.

Today, we will consider the features of setting the carburetor at maximum speeds. Make sure that the chainsaw does not develop full power, you can use a tachometer. If there is no device, then make sure that the engine does not develop maximum turns can be by ear. We are interested in a screw on the carburetor. Which is designed to set up high speeds. It is usually indicated by the Latin letter “h”, which is abbreviated from the word “high” (high or large).

To configure high speeds of the chainsaw, you will need to perform the following manipulations:

Twist the screw h clockwise until it stops
Next, weaken it at 1.25-1.5 turns
Start the tool and test the performance of the revolutions
