Makita chainsaw stalls hot. Spark plug

Why stalls macita chainsaw on hot

Hello, dear subscribers and readers of my blog! In touch Andrey LOC. We continue the topic of chainsaws. So, I already said before what should be checked in a chainsaw in order to know the cause of its malfunction. Today I will switch to more valuable instructions so that you do not look for the reason for the problem for a long time and know about how to solve it. Not the most difficult tool, but you need to care for it correctly. There are different cases, sometimes the chainsaw stalls when pressing gas, sometimes in a load, and sometimes does not work at all at all. Let’s look at different situations together and try to find the right solution.

If you find that the tool does not start and stalls at all, then you do not need to rush immediately to the service center, you can try to solve the problem yourself.

Stalls on “idle”

Sometimes the saw stalls at idle, and the muffler blocking is a common cause of breakdown. It can be easily cleaned yourself, for this you do not need a high specialist.

In addition to cleaning, there is another option, but we treat it very carefully so as not to harm the internal details of the device.

To configure the carburetor, you need to find two bolts with letters L and H. The latter must be turned, a little, only for half a turn. He is responsible for the revolution of the tool and, if necessary, will raise an idle move.

What to do if a chainsaw stalls on a gas when you press the gas

One of the most common issues regarding the work of this device: why the chainsaw is stalling when pressing gas and what needs to be done to solve this problem? In such a situation, the following actions must be performed:

• check the fuel filter;
• examine the fuel hoses for tightness;
• check the muffler;
• try to add a little speed;
• Check the condition of rubber oil seals on the crankshaft.

The saw stops working with an increase in speed

Filters are often clogged, especially when the chainsaw works almost daily. Air filter can be disconnected and washed under a stream of warm water. Before inserting in place. to dry thoroughly.

If, after disconnecting the fuel hose from the carburetor, the liquid does not flow out of it, then it clogged. It can be cleaned, or replaced with a new.

With frequent use of the tool, a gasoline pump may fail. After all, every detail has its own expiration date. It should be replaced or contacting the service center.

Why the chainsaw stalls when heated

It often happens that the motorcycle starts up on the cold, but stalls in the process of heating. This behavior of the tool can be caused by the following reasons:

• The carburetor is incorrectly configured. This problem can be identified by the way the device is launched on a cold. If it is carried out without closing the air damper, and the engine is launched without a preliminary flash, this means that after heating the motor, the fuel floods the candle. The solution to this problem is to adjust the carburetor. Details about carburetor adjustment
• Coil malfunction (ignition module). This problem can be identified by sequentially checking the spark first on the cold, and then on a hot motor. If there is no spark on the hot motor, then you need to replace the ignition coil.
• Falf in the spark plug. In this situation, as with the malfunction of the ignition module, the spark disappears when the motor is heated. It is necessary to replace the candle with a new one, and if this did not lead to the solution of the problem, then the ignition module and the distance between it and the flywheel should be checked.

Problems “Hot”

If you notice that the chainsaws are started without problems without warming up, and after heating stalls. And not to start it until it cools down, then here, perhaps several problems.

First, perhaps somewhere there is a leak of a hose, an omentum or gasket. Secondly, inspect the muffler for the presence of a car. The third reason lies in the cylinder.piston group (CPG), are there any bulletin or bumps.

Sometimes a carburetor setup is required. Another important cause of the malfunction is the ignition coil. In cases where it is out of order, the spark is lost or becomes very weak, which is not enough to light the fuel mixture.

There are cases when the master is trying intensely the engine, then on the cold, then on hot, thereby pumping fuel. Here you need to pull yourself together, transfer the damper to a “hot start” and gradually start the tool. At the same time, we knock down the speed to an almost idle and 40-45 seconds, it warms up.

Reasons why the chainsaw stalls under load

In this article of the construction site, the main reasons will be considered, due to which the chainsaws may not start or stall at the load.

The most common of all are the following reasons:

Why does the chainsaw stall when heated?

Hi all! In this article we will answer the question for what reasons when heated the chainsaws stalls. There are only three of them a little. Two of them are associated with the electric part, and one with the supply of fuel. The purpose of this article is to help in the diagnosis of these reasons. And then you can already decide for yourself whether to take up the repair yourself or is it better to contact specialists.

Well, we list these three main reasons.

Incorrect tuning of the carburetor

This is perhaps the main reason why the chainsaw stalls on a hot. It is diagnosed quite simply: when launching on a cold chainsaw, it starts with an open damper without the first short.term flash. Let me remind you that with the proper factory for a cold damper, you need to close and pull the starter until the engine tries to start and immediately after that stalls. Only after that the damper needs to be opened and the chainsaw will be already on the operating mode.

So, if the chainsaw is nevertheless starting immediately without preliminary pulling out the starter with a closed shutter to the first preliminary outbreak, then this means that there is a lot of fuel mixture initially so that the chainsaw is immediately ready to work without preliminary warming up, and later it occurs when warming up. the expansion of fuel channels, which is why the gas stomach begins to act in too large quantities and simply floods the candle, since the fuel does not have time to completely burn.

Therefore, a carburetor adjustment is required, in which you need to slightly reduce the supply of a gas stem. This is done by the rotation of the corresponding screws indicated by the letters H and L, to which there is access from the surface of the saw case. On household models, sometimes only one screw occurs.

You can adjust the eye yourself, but it is better to contact the service, since the accurate adjustment requires special equipment, which a simple user, as a rule, is absent.

The ignition coil malfunction

The malfunction of this element lies in the fact that in the cold state the coil normally organizes the flow of current to the candle, but when heated in it, opening up or, conversely, close. Because of this, the spark ceases to form and the chainsaw stalls.

Repair, as a rule, in this case consists in replacing the coil entirely. With minimal skills, this can be done and the most especially complicated is nothing here.

This malfunction is diagnosed is very simple. You just need to check the presence of a spark on the cold, and then on the hot. If there is no hot sparks, then the coil is to blame. However, the candle must be taken obviously working, that is, the one that works without problems on another working chainsaw, since the reason can be just in the candle and this third reason is in our article.

False of a candle

It is logical to assume that it is very easy to diagnose this problem if it is possible to test the candle on another obviously serviceable chainsaw. If the other chainsaw stalls with this candle, then the problem is in it.

In this case, you can assume that you are lucky, as this is the simplest and most inexpensive option for returning a chainsaw to working condition. New candles are inexpensive and change easily.

Thus, we examined the three main reasons why the chainsaw stalls on the hot. Just take the above diagnostic measures and calmly find out the reason. And on this I will allow myself to finish this text thanks for your attention and see you in other articles.

Basil starts and stalls

In cases where the tool stalls immediately after the motor has started, this may indicate problems with the brake of the chain or insufficient lubrication of the power unit. First of all, you need to check the oil level. if it is not enough, then the topping the liquid, the problem will be solved. But sometimes the level is within the normal range, and the motor still stalls. This means that the problem is most likely in the tube, according to which the oil enters the lubricant.

Also, it happens that a problem is hidden in a carburetor. Perhaps it must be debugged in accordance with the instructions for the motorcycle. But if the carburetor is strongly clogged or broken better not to try to restore its performance on your own. refer to a professional master.

Sometimes the saw cannot start normally, due to the too low fuel level-when the tool is tilted, the liquid flows from the suction tube.

Babble stalls when heated

Sometimes the tool normally starts with a cold motor, but as soon as the device warms up, the saw stops working. There are several reasons for this:

• The carburetor is incorrectly established. The fuel mixture is too enriched and the fuel simply floods the candle. The problem is solved by a decrease in gas supply for compiling a mixture.
• The ignition coil malfunction. If the spark on the candles disappears on the hot motor, then this may indicate the unsuitability of the coil. the part requires replacement.
• False of a candle. The problem is very similar to the failed reel. You need to find out what exactly needs to be replaced. a coil or a candle.

A few maintenance tips

Thorough compliance with the instructions for the operation and maintenance of the tool. a guarantee of its long and uninterrupted operation. It should be borne in mind that every detail of the chainsaw has its own resource, so they need to be changed in a timely manner.

The rules for working with the tool are as follows:

• Before each plant, check the serviceability and sufficiency of the chain tension.
• Use only a well.sharpened chain for work.
• After using the saw, clean all the nodes from sawdust.
• Turn the tire for uniform wear. Lubricate the star at the same time.
• If long storage is ahead, drain fuel and oil.

Store the chain and tire in disassembled form, since they form an electrochemical pair, and this leads to the formation of rust.

With improper operation and maintenance of spontaneous failures, not only budget class tools are subject to, but also rather prestigious models of well.known manufacturers. To maintain the performance of the chainsaw, follow the recommendations of professionals.

There is a spark, a candle is wet. how to solve the problem?

Wet candle indicates a violation of the proportion in the preparation of the fuel mixture. In this state, the detail at first is still able to form a spark, but gradually this property of a candle is lost. In addition to the improper ratio of oil and fuel, there are a number of reasons why the element floods.

• strong clobs of the air filter;
• malfunctions in the carburetor settings;
• malfunctions in the operation of the standard ignition system;
• incorrect sequence of actions when starting a cold motor;
• Poor quality of gasoline.

In the first case, the repair of the chainsaw is carried out by thorough cleaning or complete replacement of the air filter of the tool.

If when working, the tool began to consume a large amount of fuel, and engine speeds began to constantly “swim”, decreasing and age every 5-10 seconds, then the owner of the chainsaw should configure the carburetor.

With the repair of the standard ignition system, everything is a little more complicated. To do this, check the entire electrical wiring and make measurements of the gap between the high.voltage wire and the tip of the candle. If necessary, you also need to clean the ignition system from blockages.

If none of these malfunctions were found, then it will be necessary to study the instructions. Perhaps the operator performs the tool in the wrong sequence.

If none of the above helped, then the cause of the breakdown is a poor.quality fuel. In this case, you need to drain the remaining gasoline and pour new fuel with a higher octane number.

Why does not gasoline get into the chainsaw?

Carburetor needle. On cheap chainsaws, the needle in the carburetor often relies, which prevents fuel from entering. Sometimes it’s enough just to move the needle and install it correctly.

Basils. Chinese and even branded chainsaws can have low.quality seals with poor tightness. The fuel stops flowing when it begins to compress the fuel mixture through the seals. Gasoline leak is possible due to gaskets.

Check your breath

It is the fan that plays a significant role in installing a chainsaw, such a part can be found near the lid of the fuel tank, or rather. In the air hole. The respite performs a simple, but important role. It prevents fuel leakage and sets the correct air pressure. That is why the air enters the carburetor, and the failure of this element is a common reason when the fuel does not fall on the chainsaw. The malfunction of the blower will lead to the formation of negative pressure, which will prevent gasoline from entering the carburetor when trying to launch the tool.

Checking the fan is quite simple, disconnect the gas pipe from the carburetor and check how the fuel is consumed. If gasoline flows in a small stream, everything is fine if it does not flow at all. The respiratory apparatus is pretty clogged with dirt. If everything is done correctly, the part can be cleaned, sometimes it’s easier to replace it with a new. The cleaning procedure is performed manually or using a strong stream of compressed air.

There may be a lot of breakdowns with a chainsaw, and some of them are difficult to solve. If you have worked with this gas tool for a long time, you have a problem when gasoline does not get into the carburetor, but it is very difficult and does not allow you to properly run the chainsaw. Fortunately, experts have long found the reasons for such a breakdown, so we have compiled the main methods of repair.

First of all, we check for banal reasons, such as the presence of gasoline in the tank. If so, we check the process of supplying fuel from the tank through the wire. To do this, just disconnect the gas pipeline from the carburetor and try to download fuel. Serve fuel correctly through the hose with jerks, this will ensure the absence of problems with the gas tank. If the fuel does not flow even with jerks or merges too slowly, there can be reasons:

Surprisingly, even the presence of a complete tank may be the reason when the fuel does not act. So try not to fill the tank as much as possible. A crowded fuel tank can squeeze a pipe that connects to a carburetor.

Low quality gasoline

Each experienced chainsaw user knows that fuel in the tank of the tool cannot be left for a long time. The fact is that long.term storage inside the tank will cause unnecessary processes with the formation of resin and polymerization of various components. Do not leave the fuel in the tank for more than 2 weeks, and even if your tool is launched with such fuel, this can lead to the formation of soot on the details of the CCA (rings, piston).

Air filter

If the chainsaw does not receive gas in the carburetor, pay attention to the type of air filter. Incorrect work leads to the fact that the chainsaw becomes unstable and it is difficult to launch it later or stop it during operation

The air enters the device more complicated, and the mixture becomes too saturated. You can hardly start it, and the reason for this is the formation of dust.

Caution must be taken when removing the air filter, since if dust remains on it, it can get to the carburetor. Clean the air filter quite well with water and detergent

Be sure to dry the filter before installation.

Glave of a chainsaw at high speeds. a simple carburetor repair

The tool carburetor is exactly the mechanism that most owners are afraid to disassemble on their own. The reason is that this mechanism consists of many small details, the location of which must be remembered during the dismantling work. However, not everything is as scary and difficult as it might seem. To understand how the carburetor has to do with the problem of stopping the engine operation with increasing speed, you need to find out its principle of operation described on the site.

Gazes a chainsaw when pressed due to a carburetor if:

• The membrane is damaged
• Clogging of the filter element (mesh in the carburetor). Owners of tools who do not have a fuel filter may encounter this malfunction or it is simply disconnected from the fuel hose
• Sticking the needle, which can be associated using an outdated fuel mixture
• Clogging of the channels of nozzles or a carburetor is clogged
• Bending the connecting part uniting a membrane with a needle for supplying fuel to the fuel chamber of a carburetor. This part is also called a paw, since under the influence of the membrane on it, the needle moves and the opening of the channel. This paw during operation can be bent (developed) or break (when turning off the engine will not start). If the paw is bent, then it can be straightened, but this does not guarantee that the problem is soon repeated soon, so it is recommended to replace the part

It is recommended to clean and wash the chainsaw carburetor, as well as replace faulty parts and elements. After that, it can be set back, not forgetting to replace (if worn out) a sealing gasket between the carburetor and the adapter.

Babble stalls at idle

There are common cases when a chainsaw stalls at idle speeds. First of all, you need to check the silencer, and, in the case of its contamination, clean the exhaust sorrow of exhaust. Also on carburetors of some models and others. There are bolts with inscriptions H and L. respectively, gross and accurate setting. Having adjusted the bolt of L during the operation of the chainsaw so that its speed increases (to crank the bolt by half a turn), it is possible to eliminate this problem. The adjustment of the carburetor requires the mandatory presence of an electronic tachometer and is a rather time.consuming process. That is why in such cases it is better to contact professionals.

If the chainsaw stalls at the load, then the cause of this can be a fuel system or a contaminated air filter. Fuel replacement in compliance with the correct proportion of gasoline/oil or cleaning of the air filter. universal solutions of such a problem. Incorrectly cooked mixture of low.quality gasoline and, for example, machine oil, is the main reason for the faulty operation of the chainsaw, including in the case when it heats up and stalls.

Basil stalls when tilted

With a horizontal position of the chainsaw, the fuel tube lies at the bottom of the gas tank, when the instrument is inclined, the tube is above the fuel mixture, t.e. in airspace. This is the reason that the chainsaw stalls on the side.

In the event that the tool stalls at high speeds, you need to check three parts: air filter, fuel pump and gasoline filter. The air filter must be cleaned, you can even wash under water and dry well. Then 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 gasoline filter can not be checked. If on the contrary, then the malfunction was found. The soundtress can be cleaned with an ordinary needle, and the filter is carefully disconnected from the suction hose, clean it or replace it with a new. The gasoline pump is checked for wear: if the fuel does not seep through it, then everything is in order with it. If the problem is that your tool stalls at full speed is due to some damage to the pump, then this part must simply be replaced with a new.

The chainsaw is stalled and not start

If the tool is stalled and not starting to start, it is worth checking the presence of fuel in the tank. Oddly enough, it sounds, but many people forget about this and, if such a situation arises, they immediately try to repair the tool, which can lead to serious breakdowns.

In a situation when I drank it stalled, and there is still gasoline in the tank, you need to evaluate how the saw worked until this point. Maybe when working at the last moment there was an extraneous sound, rattle, ringing, power loss, or the tool stopped abruptly. All this will allow to pre.assess the situation.

The engine jammed

Quite often there is a situation when the saw worked and sharply stalled, the cause of which was the jamming of the engine, which in turn occurred as a result of a break in the piston skirt, destruction of the crankshaft bearing, the outbuilding ring of the piston fingers or the break of the piston ring.

The engine jamming is easy to determine if you pull the starter cord. In the case when the starter does not turn, most likely, it jammed, and further repair is possible only in the service center.

The cliff of the fuel wire

During the operation of the chainsaw, vibration occurs, which can cause damage or breakthrough of the fuel line of the chainsaw. In this case, the chainsaw will stall and it will be impossible to start the launch. To diagnose a malfunction, you need to conduct an inspection and determine the presence of fuel fuel.

Overheat

Overheating of the engine during operation may cause the saw to be stalled and will not start. Overheating is quite dangerous, as it can cause melting the piston in the cylinder and jamming of the engine. In the first cases of overheating, it is worth diagnosing the tool for the availability of extraneous air leaks to the engine, and adjusting the carburetor.

Air leakage, as well as the correct adjustment of the carburetor affects the maximum number of engine speeds and its lubricant, which in turn causes overheating and shaking the tool.

The main reasons why the chainsaw is not started on the video. The video will be useful for those who quickly want to start a saw, the author gives practical advice.

In case of a situation where the chainsaw is not started, it is important to correctly conduct diagnostics, determine the direction in which the malfunction should be sought. Do not use a tool that does not work at idle, as this indicates the presence of air leaks into the engine and can lead to serious problems. If the experience in repairing the chainsaws is not enough, it is better to contact a specialist who will save your time and nerves.

By acquiring any tool, everyone hopes that he will serve faithfully for many years. But it doesn’t always work out. Perhaps after some time the goods ceases to perform its functions or does not even turn on. Such a purchase can be returned or repaired for free, but observing some rules.

What can lead to himself if the chainsaw stalls “on hot”?

Gasoline equipment can be well launched in an unheated state, but at the same time heating and stalls, demanding time for its cooling, there may be several reasons:

• defects in gaskets, hoses, oil seals that need to be checked;
• a muffler, on which a carbon fiber was formed;
• possible malfunctions of cylinders and pistons, which are visible to visual examination;
• Carburetor settings were lost or incorrectly installed;
• malfunctions of the ignition coil.

Search for the focus of the problem usually starts with an incendiary candle

If there is a spark of a candle is wet, you should examine in detail the incendiary system, if on the contrary, dry. you should pay attention to fuel and everything that is connected with it

Very often another unpleasant phenomenon can be associated with this. violation of the launch “for cold”. Its causes, as a rule, are the same, therefore, attentiveness to the fuel in both cases is in the first place.

Features of the return of the chainsaw

It is not always possible to check the tool purchased in the store in the store, since even solid trade organizations, referring to the lack of conditions and fire rules, are reduced to a minimum pre.sale preparation.

• Each new model may structurally differ from previous developments. Therefore, the start of preparation by the owner of the tool for the first launch is preceded by the study of the operating manual. Work is carried out in accordance with the recommendations of the manufacturer.
• If the new tool has clearly expressed damage, does not start or is understood, it is advisable to return the chainsaw to the seller.
• The store is obliged to accept the defective goods, exchange for an identical model or return the money. The chainsaws that have clearly expressed traces of disassembly or operational damage are not subject to return.

Defective new chainsaw, is subject to exchange at the place of purchase for 14 days. After this time, warranty obligations come into force, allowing to eliminate the instrument malfunction for free in the service center.

Why stalls the chainsaw

If the chainsaws start and stall, the reasons can be different. An external inspection should be carried out before attempts to fix the tool.

If the saw stalled during operation, you should check the presence of a mixture of oil with gasoline in the tank. If the fuel mixture is over, the device will not work. In those situations where gasoline still remained, the quality of the tool should be evaluated until the moment of is turned off. The occurrence of extraneous sounds and the subsequent sharp stop should alert.

The formation of soot on electrodes can also cause difficulties in the operation of the tool. Carefully inspect the device, clean if necessary.

When pressing gas

In cases where the chainsaw stalls when you press the gas, you should check the silencer and the fuel filter. A possible cause of problem is a violation of the tightness of the fuel hoses. In some cases, the addition of revolutions helps.

Sometimes checking all the details does not give a result, the tool is suffocating, zooiling when gas is added. If the device stalls when a person presses gas, it is possible to supply fuel in insufficient amount for normal operation. This phenomenon occurs due to clogging of the carburetor or filter.

Damage can occur due to clogging with air filter dust. When you give gas, the device stops working. Do not eliminate the problem yourself, since each model has individual characteristics.

Calling may cause failure or lack of lubrication on the chain of the chainsaw. If the circuit is dry, the channels should be cleaned through which the oil is supplied to the device tire. If the oil proceeds, the presence of cracks, defects on the pipes is noted, you need to treat them with sealant.

Under load

In situations where the device stalls at load, the problem can be with a gas tank or filters. Check the quality of the fuel and change the filter.

Often the saw does not gain momentum due to the fact that the mixture flooded in the gas tank has a low octane number. There is not enough power, sufficient heating does not work, the chainsaw stalls under load.

Often, malfunctions of the component parts lead to the fact that the device stalls under load. You should check for the presence of a sucker hoses, seals, gaskets. If the details are faulty, you can try to fix them or replace them.

In cases where the chainsaw is started and immediately stalls, the fuel is not enough, the device does not heat up. Turn the device. It is important to use a suitable mixture. Different types of fuel are better suited for different models. It is necessary to familiarize yourself with the instructions, recommendations, reviews of people whose device works normally.

At idle

In those situations where the chainsaw stalls at idle speeds, it is necessary to examine the state of the muffler. If the part is polluted, the spent gases are poorly displayed, the engine cannot continue to work, stops.

The saw stalls idle and in cases where the carburetor is incorrectly configured. It is better for beginners to fix the repair to specialists, since there is a chance of incorrect setup, because of which the tool will not be able to work. Tachometer is required to adjust the carburetor.

At high speeds

If the device stalls at high speeds, pay attention to the state of gasoline and air filters, the serviceability of the fuel hoses.

Polluted air filter can be washed under warm running water. It is important to thoroughly dry the part before installing it so that the water does not violate the serviceability of the tool.

If the liquid stops flowing through the fuel hose, it clogged. You can clean the part or replace with a new.

In cases where the saw stalls at large speeds, but the liquid flows through the hose, and the air filter is clean and working, look for the cause of the breakdown in the fuel filter. Install a new one in its place or clean.

In some cases, the problem is hidden in a gasoline pump. With the wear of the component part, the fuel begins to flow through the walls. If this phenomenon is noted, a new pump should be installed.

When tilted

If the saw does not develop speed when tilted, turns off, stops working, you need to check the fuel level in the tank. If it is not too high, the device is not supplied in an inclined position is not supplied with a sufficient amount of fuel, since the fuel tube is above the mixture level.

What to do

If a malfunction is detected, you can try to eliminate it yourself. If you can’t fix the device with your own hands, contact a specialist. The master will examine the device, make professional repairs. This will avoid risks to harm the instrument during attempts to fix it with your own hands. Methods of eliminating dysfunctions depend on which part was faulty, which is why the work of the saw was violated.

If the chainsaw is started and immediately stalls, often the reason is the lack of fuel. The amount of fuel fluid in the gas tank should be monitored, the device is in a timely manner.

It is important to operate the tool correctly, following the instructions. The use of a chainsaw can not deteriorate the quality of the sawing, lead to a breakdown, damage to the device.

New technique can start tight even with a light start system. After a while, such a problem is eliminated by itself. If a person has doubts about the serviceability of the device, it is recommended to consult a master.

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.

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.

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.

If the audit showed that the contact is reliable, and the saw does not continue to start, look for the cause in the ignition unit. As a rule, a faulty block of repair and restoration cannot be subject. It will require its complete replacement.

Why the chainsaw stalls when heated

The situation in which the chainsaws are started, and in the process of heating can stall, is familiar to many who are dealing with them. The main reasons for this behavior of the saw are the following.

• The ignition module is faulty (coil). You can determine the malfunction by checking the spark first on the cold engine, and then on the hot. If there is no spark on the hot engine, then it is worth trying to eliminate the malfunction by replacing the ignition coil.
• The carburetor of the chainsaw has the wrong tuning (floods the candle on hot). You can determine the problem by the saw starting on the cold. If for cold starting it is not required to close the air damper, and the engine is launched without a preliminary flash, then the fuel mixture is formed incorrectly and after heating the engine, the fuel flies a candle and makes the launch impossible. The problem is eliminated by the adjustment of the carburetor.
• The spark plug is faulty. In such a situation, similarly to a faulty ignition coil, a spark disappears when the engine is heated. It is worth trying to replace the candle with a new one, and if this did not help, then you need to check the ignition coil and the gap between it and the flywheel.

You can check the ignition coil using a multimeter or replacing it with a deliberately serviceable. Checking the primary and secondary winding multimeter is carried out in the mode of resistance measurement mode. The indicator of the resistance of the primary winding, the working coil, is 1 kOhm. secondary 4 rooms.
