STIHL starts and stalls the reasons. Checking the filter

Stihl 180 starts and stalls the reason

German saws Stihl (Stihl) have long established themselves as a high.quality and reliable cutting tool. For various needs, the company offers a wide range:

  • Low.power chainsaws for working in the garden or in the country for cutting shrubs and rolling trees with a small diameter barrel, woodwork: MS 170 (1.3 kW), MS 211 (1.7 kW), MS 230 (2 kW) and others) and others.
  • Medium.power chainsaws that are optimally suitable for farmers, gardeners and builders: MS 271 (2.6 kW) and MS 310 (3.2 kW).
  • Supermissive saws with a gasoline engine, characterized by high performance and suitable for all industrial and economic works related to wood processing of various hardness: MS 361 (3.4 kW), MS 361 (5.2 kW) and others.
  • Electric saws and saws with a battery, for which the gas station does not need a fuel, but they are also great for working in small summer cottages: for example, MSE 250 C-Q or MSA 220 C-B (with AP 300 S and Al 500).

A light and compact tool model is used for household purposes, but, despite optimized performance, sometimes the stihl chainsaw is not started. The problems are manifested in the fact that the engine turns on and stalls, works unstable, cannot develop the set power or unexpectedly gains high speeds.

Why the stihl chainsaw is not started

For preliminary diagnosis of causes, the gas pump is checked, the appearance of the candle, fuel flow, carburetor functionality and filter condition. Pay attention to the performance of cylinders, pistons, muffler, crankshaft bearings. After preventive measures, they try to launch a chainsaw. Insufficient lubrication of rubbing spare parts also becomes a factor of poor work.

In this article, we will consider the main problems that can occur when the stihl chainsaw is launched (the spark has disappeared, the tool stalls or does not gain momentum), as well as ways to eliminate them.

Lack of sparks

Sparking is being checked on the spark plug. The functioning of the element is affected by different factors. When testing the mechanism, the reasons are revealed:

Due to work in such conditions at the contacts, the candle accumulates. The subsequent corrosion of the conductors becomes the reason that there is no spark in half of cases of malfunctions. This is because the gap between modular contacts changes. To check the spark, they make the following:

  • The tip of the high.voltage cable is removed;
  • the candle is twisted;
  • The tip is put in place;
  • The candle is leaning with a wide end against the cylinder;
  • Start the starter.

If when starting between the electrodes a bright spark appears, resembling a zipper, then the ignition unit is working. In the absence of a flash, the entire element is cleaned and the gap between the conductors is exhibited. Sometimes there is no gap between the flywheel and the ignition coil. When the flywheel is visible on its appearance, scratches are visible.

The ignition coil malfunction

The module or coil does not understand, its suitability is difficult to identify without testing devices. Modern ignition systems are strong, light and small in size. They are characterized by almost reliable functionality. Problems with a malfunction of the chainsaw due to the ignition coil can be eliminated independently.

Test the outlet wires for damage (in t. h. internal) that arise due to vibration leading to friction. If there are no cracks, then the ignition coil replacement is required. Sometimes a weak, barely distinguishable flash when heating the saw indicates a malfunction of the module. This is due to an increase in the temperature of the coil, which leads to an increase in the resistance of the transistor.

The peculiarity is that at the beginning of the spark, the spark may appear, but after prolonged use it becomes dull and disappears. Modern ignition coils in a home workshop are not repaired, therefore they are changed to suitable elements.

Fuel supply

After twisting the candle on its surface, a wet plaque is detected. This speaks of excessive supply of gasoline to the combustion chamber. For this reason, the tool does not work or stalls, t. to. Fuel is not ignited.

Another inhibitory factor is the clogging of the sapun. a small hole in the lid of a gasoline tank. It is cleaned with a needle, otherwise the chainsaw of the Stihl MS 180 does not start. To determine incorrect fuel supply, consistent actions are carried out:

  • remove the candle;
  • 2 cubes of gasoline are poured into the candle hole with a syringe;
  • put a device for ignition in place and put on a cap of a high.voltage wire;
  • The lever is transferred to the position of hot launch;
  • Twist the starter handle a couple of times.

If the tool starts and stalls immediately, then the fuel highway is tested further. Check a gasoline filter, a surge from the engine crankcase, the integrity of the partition in the pump when unscrewing the cover.

The breakdown of the crankshaft bearings

With defects in the bearings, a weak play is felt. To identify it, the flywheel of the STIHL MS 180 saw is staggering from one side to the other. The movement suggests that the flywheel shifts towards the electrodes with its own magnets, as a result of which there is no spark. To remove the mechanism, dismantle the cutting element, remove the filter lid and clutch. For the crankshaft, the lid of the manual starter is removed and two bolts are pulled.

The clutch is twisted with a clock clockwise. Remove the drum with an asterisk, change the old clutch and twist it all the way. The crankshaft are stopped so as not to break the starter. The mechanism is assembled in the reverse order. To tighten the brake handle is tilted forward, the tool is started, then removed from the brake.

Less commonly detected bearings with marriage (in the clip, the diameter of the holes is increased). To determine, disassemble and measured using a micrometer. A regular knock testifies to broken bearings. In this case, urgent repairs are required, t. to. In case of violation of the integrity of the crankshaft, a piston group and cylinder will fail.

Flies a candle of ignition

In this case, the spark is not able to ignite the fuel, which in large quantities enters the firebox to burn the combustible mixture. If it floods the candle, then the carburetor is faulty or the cold motor is launched incorrectly. The engine is made, the procedure is performed with the ignition turned off and far from the open flame. To ensure fuel ignition at the time of start.up, they clean the mechanism:

  • They twist the candle, wipe dry, dried for half an hour;
  • A large layer of carbon fiber is removed with a file;
  • Between the contacts, the gap is regulated;
  • The tool is turned upside down and gasoline is drained;
  • In this position, the starter is twitched several times (to remove fuel residues);
  • They are assembled in the reverse order.

The main causes of malfunctions and ways to eliminate them

The main element of any motorcycle is the engine

Each engine, no matter what manufacturer (“Partner”, “Husqvarna”, “Stihl”) has its own motorcycle resource. The limit of this resource depends on the quality of operation and storage conditions

stihl, starts, stalls, reasons

Sometimes a saw can fail before its laid resource, due to the poor quality of the fuel and oil used. After a motolimite or intensive work with a saw, unpleasant consequences arise when a chainsaw:

  • Does not start.
  • Starts, but immediately stalls.
  • Works, but interruptions in the engine are observed.
  • The engine does not develop full power, when you press gas. stalls.

The consequences are very diverse, as well as the reasons for their occurrence:

  • Problems with fuel and oil, their ratio is violated or other grades of fuel and oil are selected, which were not recommended by the manufacturer;
  • The fuel system clogged;
  • Problems with the ignition system;
  • Carburetor settings were lost;
  • The fasteners of components of the engine weakened from vibration.

Each problem can be both independent and complex. Sometimes these problems can be superimposed on each other. It is necessary to consider them in more detail.

The chainsaw is not started

There was a need to work. There are no chainsaws, what are the reasons and methods of elimination exist? Modern saws have the same principle of operation and device. Therefore, we will consider on a specific example: what are the reasons that the STIHL 180 saw does not start?

It is necessary to check the condition of the candle. Due to soot or the wrong gap between the diodes, the spark does not pass. This does not detonate the combustible mixture. Clean the cargo, adjust the gap, check the presence of a spark. To do this, put on a tip with a wire on a candle, lean it against the cylinder (or any other metal surface), pull the starter. In the presence of a spark. screw the candle and start the engine. Along with manipulations with a candle, it is necessary to clean and rinse the air filter.

If the launch does not occur, then it is necessary to adjust the carburetor. We set up a setting according to the instructions for a specific chainsaw. These actions are usually enough to launch the engine. These recommendations can be used for malfunctions on other STIHL models (MS142, 240, 250, 350) and even on models of other manufacturers.

Saw and stalls

Typically, the reason why the chainsaws start and stall is poor fuel quality and violation of the composition of the combustible mixture. There are also causes, such as: clogging of the fuel system, improper carburetor adjustment.

If the fuel filters are cleaned, the quality of gasoline is good, then the simple add.in turning “L” usually helps, it is he who is responsible for idle speeds.

Basil stalls at load

The engine started, works evenly at idle, but the chainsaw stalls when pressing the gas. The reasons in this case are: clogging of the air filter, clogging of the fuel channel, poor quality of the fuel mixture, improper carburetor adjustment, problems with the ignition system.

It is necessary to drain the contents of the gas tank and pour good fuel, with the correct ratio of gasoline and oil. Check the fuel hose, its integrity, wash the tank and hose if necessary. Make additional adjustment of the carburetor.

The problems that arise is easily eliminated with your own hands. Do not require large costs, only it is necessary to periodically perform prevention to cleanse the chainsaws of dirt. Pour good fuel and use the oil declared by the manufacturer. Fuel mixing with oil is recommended to be done immediately before working with a chainsaw.

There is no need to keep the finished mixture, since the formation of tarry fractions occurs. These compounds adversely affect the piston group. At the beginning of the work, it is necessary to let the chainsaws warm up a little, give the load gradually. Compliance with technological requirements will allow your chainsaw for a long time to serve.

Chinese and new chainsaws do not start what could be

The popularity of Chinese chainsaws has no boundaries. This is due to their main advantage. affordable cost. over, often among the owners of Chinese chainsaws, questions arise about the problematic launch of the tool engine. Before you find out why the Chinese chainsaw is not started, one feature should be noted. the design of these tools is no different from German and other manufacturers. That is why the reason why the chainsaw is not started can be detected on the basis of the above algorithm.

Chinese chainsaws are very sensitive to fuel quality, therefore, in the diagnostic algorithm, fuel quality testing is in the first place. The use of poor.quality fuel leads to the fact that the tool does not work at full capacity, its service life is reduced, and difficulties arise with the launch of the launch

The instructions for the tool indicate the recommended type of gasoline and oil, which is important to use in order for the Chinese chainsaw to work for a long time and at full power

If you bought a new chainsaw, and it will not start, then here you need to start the search for faults with the return of the tool to the store. Make sure that you start the tool engine correctly, and if you cannot achieve a positive result, you need to return the tool to the store under warranty. An attempt to independently search for a malfunction will entail the abandonment of traces, as a result of which a guarantee can be canceled.

It is recommended to once again check the correctness of the preparation of the fuel mixture. If everything is done correctly, but the engine of a gasoline tool does not start, then there is a high probability of factory marriage. Marriage can be with any detail, but this should already be determined in the service center of the store.

Why is a gasoline saw go out when I press on gas: causes and solutions

Often, the owners of the chainsaw have to deal with their breakdown, and it does not matter which model of this type of equipment, since the nature of the failures is almost the same for all. Well, this is a chainsaw stalled and what’s next? Undoubtedly, you can include equipment in specialized services that will repair your “iron friend” for a fee. But, as they say: why pay more?

In the end, you can personally disassemble the tool and repair it, since the breakdown can be insignificant, and for this you will have to pay a lot. But, of course, in order to return the tool to life, you must be able to understand the reasons for its refusal and how to eliminate it. So let’s study! In this article you can find answers to questions about situations where the tool simply rushes after a direct touch of gas. So let’s start.

The main elements of the chainsaw

Before we begin to understand problems with the breakdown and repair tools, let’s first find out what the chain came from. First of all, I would like to note that this tool belongs to the category of equipment whose work depends directly on.

It is also important that the chainsaws are equipped with an engine with one cylinder, and whose work is done on fuel such as gasoline. It is worth noting that, despite the resemblance to other tools, he does not have a gearbox. And it is replaced by a kind of chain single.stage gearbox through which the movement of the chain itself (saw) is produced.

In fact, chainsaws are a fairly simple design, but this does not prevent it from being reliable, practical and capable of fully ensuring immediate continuous and cyclic work even in rather difficult conditions. This tool consists of a huge range of certain elements of “vital” for proper and productive work. This carburetor, device for. Tire equipped with a chain and other elements.

Before buying a chainsaw, be sure to study all the options and select a suitable brand of a chainsaw.

To simplify your choice, we have made a chainsaw rating for you for reliability.

If you have a limited budget, read the article about the manufacturers of the chainsaw.

Characteristic and possible reasons for the refusal. Eliminate the problem with your own hands

Chainsaws. Pretty reliable and simple design. Therefore, if you carefully take care of them and deal with them based on the recommendations of the manufacturer, then they fail, very rarely, and quite quickly, various types of failures are eliminated. But if you are faced with such a situation and want to repair your tool yourself without addressing professionals, read the information presented below.

In fact, it is impossible to unequivocally and accurately determine the reason why the tool does not start or kiosks when you press the gas, since many factors affect this. But do not forget that starting with the fact that the chainsaws are equipped with a simple two.stroke engine, conditions such as lubrication, fuel, spark and air are important for its effective operation.

stihl, starts, stalls, reasons

Therefore, the carburetor directly participates in the preparation of the fuel-air mixture, the filter cleans the air of dust, the ignition and the light of the ignition create a spark, and the lubricant. In gasoline.

Therefore, it is necessary to look for the reasons for this kind of breakdown in a sequential order, starting with simple and gradually moving on to complex. And this is an important factor in proper repairs, since a person who, not taking into account this, begins to analyze the carburetor, is at risk. Since this type of device must be repaired or adjusted directly in special workshops (read about the tuning of the carburetor).

    It is important that for the non.precise operation of the device it is necessary to directly process the fuel. Since, if such a mixture is not prepared correctly, most chainsaws simply will not begin. Therefore, not every owner will guess the reason for the fuel failure. Therefore, in order for your tool to always work correctly, you need to use exclusively high.quality gasoline for the mixture.

Nagaz repairs of the blinzopila and just use the oil produced by the manufacturer of your tool. In addition, it is important to prepare the type of mixture in the amount that you use for one or two weeks, but no more (see. A share of gasoline and oil for a chainsaw).

Since otherwise the excess mixture directly in the canister will lead to the fact that it will lose all its octane properties, and this will lead to significant problems with the tool.

  • In addition, the cause of the violation may be direct filling out the candle mixture during the operation of the mechanism. To solve this problem, it is necessary to unscrew and dry the candle, but remember that it cannot be burned in any case. Excessive fuel should be merged through the hole (candle), wait 20-30 minutes, then set it in place and repeat the attempt to start the tool.
  • Chainsaws stop when you press the gas due to the fact that there is no spark. This can happen if there is no good contact between the tip and the wire (high.voltage). However, if such a connection works correctly, but sparks still do not exist, then the whole reason. This is the ignition unit (electronic). It is important to note that such spare parts cannot be repaired, so they can be replaced. Checking a candle

Do not forget that by studying the candle, you can get important information about the breakdown of the chainsaw. Since, if its surface is dry, then the reason for this is a cylinder that does not directly supply fuel. That’s why you should in stages check the entire range of your ideas. If the candle is in black carbon, this means that the carburetor works incorrectly, that is, it supplies a lot of fuel or pours oil directly into gasoline.

Other reasons and solutions

If the chainsaws still do not start and the reason is not in the above details, you need to look deeper. Other common faults include:

About the shuttleness of the pulse in the channel of the pipe from the engine crankcase;

There is no fuel supply from the carburetor;

Repair of the above malfunctions is carried out either independently, but of course it is better to give the chainsaw to the master, you can do diagnostics yourself. Also, during diagnosis, the following indicators should be checked:

Compression is checked both using a special device and manually. To make sure that the compression is “by eye”, just remove the candle and insert your finger into the cylinder hole. After several times, scroll through the starter and if the finger draws into the hole, there is a compression.

I think many had to use a chainsaw of such a brand. And not just use, but regularly perform the most diverse work and be convinced of the high operational characteristics of this tool. It is no coincidence that such a distribution of these products, given that in addition to power, this tool is distinguished by a graceful design. However, we must remember that this is still a technique in which the work resource is limited. Therefore, each owner of such an unit at a certain moment is faced with the need to repair. Further, we will talk about the features of the repair of the chainsaw of Stihl 180.

General information

The characteristics of this saw are the reason for the pride of the German manufacturer. At the same time, the unit is a tool that is designed to perform a small amount of work. The tool is positioned for domestic use, which confirms the intensity of its operation, which should not exceed 20 hours a month. Having at your disposal such an unit, it will not be difficult for you to maintain order in your garden, to prepare firewood for the winter, as well as clearing the sites. At the same time, he will be able to help you in solving other tasks where there is no need to perform complex manipulations.

Main characteristics

The saw considered can be considered a compact option, because its weight is only 3.9 kg. At the same time, it has an oil and fuel tank of a large capacity. A two.stroke engine helps the device with its working functions, the capacities of which are enough to solve simple problems. In addition to this during operation, this tool does not create strong noise, the level of which does not exceed 98 dB. For ease of understanding, it is enough to say that a person’s speech creates noise at 76 dB.

  • Stihl 180 chainsaw has a power of 2.6 watts. In principle, this is enough, remembering that it is a tool for household use.
  • The oil tank capacity is 0.145 liters, fuel. 0.25 liters.
  • The tire provided by the design has dimensions 350 mm, while the step is 0.325 inch.

Cumbbound device

As in the case of other saws, the role of the main device providing the launch is performed by the carburetor. Considering in more detail the carburetor, which is equipped with the chainsaw of the Stihl 180, it should be noted that it has a single setting screw. In other words, it is a kind of blanket adjustment screw. At the same time, the jacket, on which there is a full load, is all the time motionless.

In other words, adjustment against him is not applicable. In turn, there is no way to influence the full load. It is also necessary to pay attention to the factory settings, due to which the supply of the air fuel mixture is carried out directly to the engine. over, this principle is maintained regardless of the operating conditions of the tool.

If the chainsaw of the Stihl MS 180 stalls at idle, does not gain power when pressed on gas or completely stalled at full speed, it is necessary to diagnose the fuel system and check the crankcase for tight. You can do this yourself, but you need to have certain skills. If you are little familiar with two.stroke saws, it is better to turn to specialists, t. to. This technique is quite capricious and any errors are expensive.

The main reasons for the gas station breakdown

Although motorcycles are a simple device, from time to time in its work, problems arise, which can only be eliminated by disassembling. The following malfunctions can be given as examples:

  • a chainsaw is not gaining momentum;
  • chainsaws stops functioning in the cut;
  • The chainsaw is started and stalling;
  • a chainsaw loses its power;
  • Basil stalls when pressed.

Most often, the malfunctions are associated with interruptions in the functioning of the motor, as well as with the problems of other systems and nodes. The correct handling of this technique is of great importance. When fulfilling all the rules for using a high probability problem lies in the most obvious. When searching for the causes of problems, it is advisable to start by checking the simplest part of the motorcycle and end the most difficult.

Checking the main chainsaw systems

If the chainsaw refuses to work normally, it is necessary to make sure that all the conditions required for its normal functioning are provided:

Then you need to sequentially check the functioning of all its elements. First you need to check the fuel tank. If the cause is not in volume and not as fuel, then the ignition candles may be a probable cause of a malfunction. The gap in the candle should not exceed 0.5 millimeters. If he is too small, this means that the Nar was deposited on the candles. In this case, the candles should be removed, cleaned them, and then install them in place and try to start a chainsaw. In addition, it is advisable to completely change candles from time to time to new ones, even if they are in good condition.

Then you need to check the condition of the fuel filter and carburetor. Independent cleaning of the fuel filter is a simple task, but the repair of the carburetor is best entrusted to specialists.

Basil starts and stalls. the reason

If the chainsaw is started and stalling at the first attempts to do the work, then the reason may consist of problems with the brake of the chain or in its jamming due to lack of lubrication. In this case, the level of oil is measured. If the lubricant volume is sufficient, then the reason may be in the tube that leads it to the lubricant mechanism.

Another reason may be a carburetor breakdown. If he needs only adjustment, it can be done independently in accordance with the instructions. If the carburetor needs to be cleaned or repair, then you can not do without the help of professionals.

Another possible cause of this malfunction is a low fuel level in the tank. In this case, the motorcycle is stalling when tilted, since the remainder of the fuel mixture is in the part of the tank, the opposite of the place where the suction tube is located.

How to start a chainsaw correctly?

No matter how much we would like, but often the human factor is the very cornerstone, which acts as source of many technical problems, which he himself then heroically eliminates. The same thing is with a chainsaw, which must not only be used and stored correctly, but, oddly enough, even start.

All models of chainsaws have their own characteristics, but usually the schemes of their assembly and launch are very similar. Consider in stages where to start your acquaintance with a saw and how it can be launched into work.

To study the instruction manual, paying attention to the start and shutdown mechanism, which usually pays separate attention; Lower the adjustment lever, pre.squeezing the gas; With sharp jerks, pull the starter handle until the ignition starts, after which the adjusting damper is moved to the upper position; Resume the start of the starter, without stopping it before starting the system; Click on the gas once and immediately release, warming up the tool; Fix the lever in the 1st position; Engage in the power of the motor with the highest position of the damper

Ural chainsaws: malfunctions and repair

Any tool breaks. And this is a fact. As practice shows, foreign modern motorcycles suffer from breakdowns at least domestic benzo.tools.

Among the typical breakdowns of the Ural chainsaws, malfunctions with motors are most often found. They may not turn on, keep a blank stamping, stall under load or not turn off at all.

There may be several explanations that the Ural chainsaw is not started:

  • lack of fuel, its low quality or incorrect cooking proportion;
  • malfunctions with the fuel system: since the gas tank or fuel supply tubes are sealed, which, in addition to everything, are also littered;
  • faulty spark plug or flywheel. as a result, there is no spark required for fuel ignition;
  • a contaminated air filter through which air does not pass, which means oxygen to start the combustion process;

If the chain saw starts and stalls, the reason should be sought in a carburetor. It is necessary to adjust its nozzles so that fuel and oxygen are supplied accordingly to the load that is expected from it.

The situation when the motor heats up and stalls is also familiar to many users of the Ural benzo.tool. Fix it will help replace the spark plugs, oil, cleaning the air filter or replacing the piston.

A working motor should work exactly without jerking

The ringing knock of the engine on idle chainsaw “Ural” is the reason to pay attention to the cylinder. He could be damaged and need to replace

Identification and elimination of obvious malfunctions of the chainsaw.

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

  • The presence of a spark on the spark plug;
  • Fuel supply;
  • The condition of the filters;
  • The work of the sapuna built into the fuel cover of the stalling unit;
  • The functioning of the graduation channel.

Spark check on the spark plug and elimination of the causes.

The first stage in the search for the reasons why the gasoline saw is not started is checking the spark on the spark plug. There are many factors affecting the work of this element. However, the main ones at the initial stage of tool defect are:

  • Improper carburetor adjustment;
  • The presence of more than the amount of oil in gasoline;
  • Flowing the air filter.

All of them contribute to the formation of soot on the electrodes of the candle. In 50 cases out of 100, the saws are not bungled on the cold due to the lack of spark due to the deposits of soot on the electrodes and their corrosion. As a result, there is either a decrease in the gap or its increase.

Checking the spark plug in non.working chainsaw

Checking the presence of a spark is quite simple. This will need:

  • Remove the tip of the high.voltage wire;
  • Unscrew the candle;
  • Put on the tip back;
  • Lean the candle with a skirt against the cylinder;
  • Start the starter.

If a good spark is observed at the time of starting the chainsaw engine between the electrodes, then everything is in order with the ignition node. If it is not, then it is worth cleaning the element itself and checking the clearance of the electrodes. If necessary, using a special probe, adjust the distance between the contacts.

In candles of different manufacturers, the distance between the electrodes may fluctuate. In some it may be 0.5 mm. Others have 0.2 mm. Therefore, carefully study the recommendations of the manufacturer.

Sparks on the spark plug may not be for other reasons. Of the main malfunctions affecting the poor launch of the chainsaw and unstable operation of the internal combustion engine at idle, from which the tool may stall, the following can be attributed:

  • Overflow of the candle canal with fuel;
  • Lack of contact between the high.voltage cradle and the tip of the candle;
  • The failure of the ignition unit.

How to launch a cold chainsaw if the candle channel is constantly filled with gasoline? To eliminate the problem during the start of the tool, you can use the following algorithm:

  • Twist a candle with a special key;
  • Wipe it with a clean and dry rag;
  • Dry for 20 30 minutes;
  • Remove the corpuscles with a file and adjust the gap between the electrodes;
  • Drain the remaining fuel from the candle channel and dry it;
  • Collect everything and try to start a mechanism.

As a rule, these measures are enough to start a chainsaw and perform work. However, this extreme measure does not eliminate the main reason why the engine does not start or stalls. the incorrect operation of the carburetor, which needs subtle adjustment.

In the case of the absence of a spark with poor contact of the high.voltage cradle with the tip of the candle, it is necessary to check the connection. Checking can be carried out using a regular tester. If a defect is detected and it is eliminated, a chainsaw should start without any problems.

Other reasons

Here, first of all, this refers to the wear of the cylinder, piston, rings, as well as crankshaft bearings. The unusable of these elements ultimately leads to a decline in compression (pressure) in the cylinder. You can control the state of the CPH along the way when you remove the muffler. After dismantling this part, you will open a window through which part of the cylinder is noticeable. If bunches or scratches are visible on it, then it will have to be changed.

Details for repair can be purchased in special stores or the Internet

Next, you need to check the compression. In the absence of a special device, turn the candle, shut up the hole with your finger and pull the starter’s cord. With good pressure, the finger will be sucked inward. If there is a compressometer, but it must be inserted into the candle hole. Also turn the crankshaft by means of the starter and look at the testimony of the device. Normal parameter-8-9 kgf/kV. cm (which corresponds to 0.8-0.9 MPa). The reason for a low compression may not be in a worn cylinder or piston: sometimes it is enough to replace the overwhelming rings.

Everyone who is familiar with a benzor.instrument knows that sometimes the equipment works with interruptions, or maybe at one point to stall and no longer start up. The reasons why the chainsaw is not started, we will try to consider the most common of them.
