The new chainsaw does not start hot. Not starting on cold

Chainsaws do not start for hot reasons

To facilitate physical labor, humanity came up with working tools. They serve to influence objects and materials. There are mechanical tools and those that are driven by pneumatic, hydraulic drives, fuel energy or electricity. Tools are used in construction and for small repair work in everyday life. One of the most popular tools is chainsaw. This is a reliable tool that can be used to saw out solid objects and materials and their formation. But not always a chainsaw works properly. This article will consider cases in which the new chainsaw refuses to work, the reasons for this problem and methods for eliminating it.

One of the most nasty phenomena. When I was going to chop wood, and the chainsaw did not start. Many people face this phenomenon not only owners of cheap Chinese chainsaws, and branded profiles. If you are faced with a situation where the chainsaw engine does not start, then do not rush to take the tool for repairs. Ordinary preventive acts help to rapidly regain the performance of the tool. The procedure for conducting preventive measures to restore the performance of a gasoline unit is described in the material.

After winter I can’t start a chainsaw what can you tell

If you use a chainsaw in winter or in summer, then with the coming of spring, when there is a need to prepare firewood, a malfunction is often observed in the form of the impossibility of starting the tool engine. The prerequisites can be different, but the first step. Check the presence of gasoline in the tank. If the chainsaw was not used for a long time, but the fuel remains in the tank, then the difficulties when starting two.stroke engines are associated with a premise of stagnation of fuel.

If the fuel in the tank was not merged before storage, then there is a great opportunity that a cork was formed in the carburetor. You will need to disassemble the carburetor for you and clean it. In order not to resort to these steps, you can make the next:

• Unscrew the spark plug and inspect it. If it is dry and has a true brown color, then fuel is not supplied to the cylinder.
• 20 grams of fuel consistency are drawn into a syringe and sprayed into a cylinder
• The spark plug is twisted and the engine starts
• If the ignition system works in an affirmative way, the chainsaw will start

When the engine starts, the purchased cork in the carburetor breaks through, and the engine will work normally. If the engine starts and stops on the chainsaw, then the function of adding fuel to the cylinder should be repeated a couple of times. If the samples end unsuccessfully, it is necessary to clean the carburetor, but at first check the serviceability of fuel and air filters, the ignition module and clean the exhaust channel (silencer).

Difficulties with starting a chainsaw cannot be excluded for subsequent reasons:

• Attenuation of the electrodes of the candle
• Oxidation of contacts of the spark plug wires
• Damage to insulation of a high.voltage wire
• Ignition coil failure
• The need for the carburetor option

Difficulties with starting a chainsaw appear at some point. It all depends not only on the properties of the tool and its price, and on the characteristics of the care, operation and storage of the tool. With proper care and storage of the tool, you will never have troubles with starting the motor of your chainsaw.

The installation system device

A key role in any chainsaw is played by a carburetor power unit of a two.stroke type. Its power directly depends on the selected model and purpose. The second important mechanical node in the device is considered the saw part, which consists of a tire, a cutting chain and a chain wheel. Data parameters of the components may vary.

With lubricating mixing, it is carried out using special oil, which is poured into a specialized tank, it is located on a manual block. Separately, it should be distinguished that the volumes of the oil tank and fuel are calculated in such a way that their contents, as a rule, ends at the same time.

Fault options and elimination methods

Regardless of the brand of the chainsaw. Champion, Husqvarna 236 or Patriot, the reasons for poor work are identical. Options why the stihl chainsaw is not started, the mass is the following.

The chainsaw is poorly started on the cold

If the saw is poorly started on the cold, it means that it does not have compression. This is due to abrasion of rings due to long-term operation. It turns out when the user is trying to start Champion 137 in a cold state, compression for this manipulation will not be enough.

In this case, it is not recommended to systematically pull the handle. In the end, the unit will nevertheless start, but at the same time other mechanical nodes may break off. In this situation, you need to replace the erased rings with new.

The chainsaw is not started on hot

Here the reasons lies in the filing of the engine and get wet of the candles. Here’s what to do in such a situation:

• rearrange the air damper in the middle position;
• well make the components of the parts;
• start the device for 10 seconds;
• transfer into the mode of operation at idle;
• on a chainsaw caliber or other model completely open the damper.

Next, just start the motor at idle with pulling the handle. If the engine does not overheat, it will easily start.

In the event that this option of eliminating the malfunction did not help, then the motor has already managed to cool strongly. Make a fiction of half.gas according to the recommendations from the instructions and repeat the operation.

You should also try to scroll through the cold screw in the direction of movement of the clockwise. The higher the speed of the rotation in the equipment, the easier it is to start it. You should know that the chain at idle should remain in a stationary position.

The chainsaw is poorly started and stall immediately

In this situation, the reason is the filling of suppositories with gasoline at the moment when the user tried to turn on the unit. A small volume of fuel accumulates under the candle electrodes, which is why there is no spark in the equipment.

Removing a candle and its thorough drying will help to solve the problem. In addition to these actions, you can additionally fragment. But this manipulation should be carried out exclusively using a gas burner. In another case, a small cargo in the field of electrodes may form. After complete drying of the candles, you need to drain the excess fuel and leave to dry the equipment itself.

Chinese saw does not start

It should be noted right away that Chinese devices do not have a distinctive features from other analogues. They are also reliable and productive, moreover, they cost less. The only thing that is necessary for this device is necessary is to use only branded oil and fuel.

Most units do not work well on the fuel of domestic manufacturers, gasoline clogs channels and, as a result, fuel does not enter the motor. Use fuel either of high quality or from the manufacturer of the saw itself.

Why is the new saw not working

New equipment should not have problems with the wear of functioning mechanical parts, since the model came out only from the conveyor. Such untidiness may occur in the case of the acquisition of demonstration technology, which was more than once used to advertise the company. The cause may also be improper operation of the unit, which does not comply with the recommendations from the instructions.

First of all, you should check whether all parts and components of the elements are installed in their places. Still, for example, Husqvarna will not start if the fuel mixture prepared without taking into account the necessary proportions was poured into it.

But if all the recommendations are followed, each part is carefully recorded in its place and the equipment was not purchased from the stand, probably the buyer came across a defective device.

The tank is not enough fuel or it is of low quality

This is one of the most common reasons. Users of gasoline technology, in order to save, often use budget fuel. At first, the unit will regularly perform its work, but the problem will certainly arise after several months of operation.

It should also be remembered that fuel has a shelf life, it should not be stored in the tank for more than three weeks. Such liquid with constant contact with oxygen quickly loses the octane number. This makes gasoline completely unsuitable for use.

Problems with filters

Polluted filters are one of the main factors of the “non.launch” of the chainsaw. Check the air filter for cleanliness, it is located under the clutch body. The fuel cleaner is located directly in the fuel tank.

The location of the air filter and the spark plug

In addition to everything, you should examine the bars in the gas tank. For diagnostics, you should remove all the clogged parts for a while, start the device without them.

How to “run” a chainsaw correctly

In order for the new equipment to work normally, it is necessary to run it correctly.

• First you need to prepare a fuel mixture, the proportions of which depend on the power:

Why is the chainsaws badly starting

Consider each reason in more detail.

Fuel and air filter

Pollution of the main filter elements of the chainsaw, adversely affect its work.

For example, a dirty air filter will provide air supply to the carburetor in full, which will affect the quality of the fuel mixture and normal engine start. Fuel filter pollution will make it difficult, or even reduce the supply of gasoline into the carburetor and make the engine to work impossible.

Reduced compression

One of the frequent cases of the difficulty starting of the chainsaw is the wear of the CPG (cylinder.piston group).

As you know, for the normal launch of the chainsaw in its engine, compression should be present. It is necessary for the normal compression of the fuel mixture in the engine cylinder, it also affects the operation of the gasoline pump.

During the operation of the tool, the value of the compression indicator falls, and the chainsaw begins to start poorly.

The reasons for the lack of compression, or its decrease, can be natural, t.to. The engine wear out during operation. Problems can also be caused by serious breakdown, for example, Zadir CPG, or breakdown of a piston ring.

A sign of reduced compression is the weak resistance of the starter during the start. With reduced compression, a decrease in the power of the chainsaw is observed, which negatively affects its performance. The problem of replacing piston rings, or completely CPH, is eliminated.

Carburetor adjustment

Not correct adjustment of the carburetor will cause the chainsaw will not develop full power. It will be bad to start, or not start at all. The setting of the carburetor directly affects the quality of the fuel.air mixture, which is necessary for normal starting and further engine operation.

If the carburetor is improperly adjusted, the fuel with the air will be present more, or less gasoline than required, and the mixture will not be ignited even with normal sparking.

Excess gasoline in the mixture, it is customary to call overflow. Characteristic signs of overflow, it is a wet spark plug, after several unsuccessful attempts to start a chainsaw.

Spark plug

Spark plug is one of the main elements of the ignition system. On its electrodes, a spark is formed, and when this element fails, it will be difficult to start, or it is not at all possible.

The candle can completely refuse, or work with interruptions or give out a weak spark. Checking the candle is quite simple, for this you will need to unscrew it from the engine, attach to the cap of the high.voltage wire and, putting it on the cylinder, pull the starter. If the candle is in order, the spark will be powerful with a bluish tint. Weak spark with a reddish tint, a sign of a problem. A defective candle needs to be replaced.

Ignition coil

The reason that a new chainsaw is not started, or it starts poorly, may be a ignition coil. Modern chainsaws are equipped with electronic ignition coils. This part is not subject to repair, and, as a rule, in the presence of a defect, it completely changes.

Gap between the ignition coil and flywheel

An unbelievable gap between the flywheel and the contacts of the ignition coil affects the quality of sparking, which in turn is responsible for the normal start and stable engine operation.

Consider each reason in more detail.

Fuel and air filter

Pollution of the main filter elements of the chainsaw, adversely affect its work.

For example, a dirty air filter will provide air supply to the carburetor in full, which will affect the quality of the fuel mixture and normal engine start. Fuel filter pollution will make it difficult, or even reduce the supply of gasoline into the carburetor and make the engine to work impossible.

Ignition coil

The reason that a new chainsaw is not started, or it starts poorly, may be a ignition coil. Modern chainsaws are equipped with electronic ignition coils. This part is not subject to repair, and, as a rule, in the presence of a defect, it completely changes.

Gap between the ignition coil and flywheel

An unbelievable gap between the flywheel and the contacts of the ignition coil affects the quality of sparking, which in turn is responsible for the normal start and stable engine operation.

The chainsaw is not started on hot

In cases where the chainsaws do not start hot, you need to conduct a visual inspection of all the main nodes of the chainsaw. Inspection should start with the spark plug. Check the spark, inspect the surface of the candle electrode, these actions will help establish the direction in which you should look for the problem.

Malfunctions in the ignition system

If, when examining a candle, it is found that it is wet and sparking on the contacts does not occur, this means that the problem should be sought in the ignition system, inspect the coil, check the gap between the flywheel and contacts of the coil. You can also check how tightly the cap of the high.voltage wire sits on the candle, and the candle itself. Try to replace it with a new.

Problems in the fuel system

If during the examination it was found that there is a spark, and the candle is dry, it means that the problems are in the fuel system. Its check should start with the fuel filter. Next, you need to inspect the fuel hose and its fastening to the carburetor, pay attention to, on the fuel leaks from the carburetor and the presence of gasoline in the air filter housing. It is advisable to start removing the carburetor only if the visual inspection did not allow determining the cause of the breakdown.

A characteristic feature of the problem in the fuel system is an excessive amount of fuel in the engine cylinder. As a rule, the signs of this are an overly wet spark plug and the presence of a spark on the contacts of the candle. In this situation, it is necessary to turn the chainsaw so that the candle hole is directed to the bottom. If gasoline will flow from the cylinder, then the reason that the chainsaw does not start, it is transferring fuel to the engine.

“Floods” with fuel, sometimes due to improper adjustment of the carburetor, or its malfunction.

The process of adjusting the carburetor can be found on the example of the Champion 254 saw, watching the video instructions.

Stopped chainsaws of Chinese

Chinese.made chainsaws require a special approach in the repair. But do not think that Chinese models are poor.quality consumer. The instrument of the middle price category is distinguished by power and reliability of use. What the Chinese chainsaw does not tolerate is bad fuel, poured inside.

The quality of fuel and oil, the owner of capricious Chinese equipment will have to be monitored carefully. Do not fill the first gasoline in hand. He will ruin the chainsaw and restore it will be difficult. In order not to make a mistake with fuel, pour it the same brand as your tool.

Restore the work of the tool

To restore the saw, it doesn’t matter the Ural or STIHL brand, you need to know the place of dislocation of the breakdown.

First, check and change the unsuitable fuel mixture. If I still did not start, then we check further on the items.

The problem is in the candle. we pull out and dry. In no case should you pierce it, because this will lead to a malfunction of the part. 30 minutes after drying, you can insert a candle back, before checking if there is no fuel left in its place.

In addition, the candle may just break, so it is better to have a spare to exclude the cause.

Another reason that the tool starts and stalls is poorly contact between candles and a high.voltage wire. If everything is in order here, but there are still no sparks. perhaps the ignition unit itself has broken. Such a breakdown can only be fixed by replacing it.

Filters

If the chainsaws worked for a long time, then clogging of air or fuel filters is not excluded. In the first case, the desired portion of air will not fall into the cylinders, the combustion of the fuel mixture will not occur. If the fuel system is closed, the supply of gasoline mixture will stop.

The element cleansing air should be removed carefully, the dust should not fall into the carburetor. The element needs to be blown, rinse with water and soap, dry and also install it back.

To check the condition of the fuel filter, you need to remove the hose from the carburetor, try to pump up the fuel manually. If the stream is too weak or completely absent, then the filter needs to be replaced or washed. You can purchase a new one from the dealer, or contact the workshop workshops.

Checking a candle

The operation is similar to the one conducted by all motorists with gasoline engines. If there is a new and 100% work candle in the reserve, then the easiest way to put it and try to start a chainsaw. At the same time, the old one should be examined: a strong cargo says that the engine works incorrectly. If there are no deposits, perhaps the gap between the electrodes has been violated, because of which the spark ceased to form or was too dull. The distance between the contacts varies within 0.2-0.5 mm.

Why is the chainsaw stall under load

In some cases, chainsaws are unable to work normally with a load and just stalls. A common cause of this behavior is the wrong adjustment of the carburetor, or air leaks through the crankshaft oil seals or a carburetor laying. And such behavior can also occur due to the leakage of the carburetor.

Diagnose the cause and eliminate the fact that the chainsaw is started and stall under load, best in the service center, t. to. A special tool is needed to check the tightness of the carburetor and the engine crankcase.

The saw unable to work under load will also uncertainly hold the idle speed. They will “swim”. Diagnostics begin with verification for the tightness of the crankcase and carburetor. If the air leaks are found through the crankshaft oil seals, they must be replaced. If an air leak is detected in a carburetor, it is possible to eliminate the cause by installing a repair set of gaskets.

Only after the above actions did not give the result and the engine crankcase with the carburetor is sealed, you can proceed to adjust the carburetor.

The reason for this algorithm is as follows, if the air leakage from the crankcase is not eliminated, but the carburetor was simply adjusted to the normal operation of the engine, then the fuel mixture will contain a larger amount of fuel than it is required with a tight crankcase, which in turn will significantly increase its flow rate. Also, most likely, soar will appear in the engine, which will also adversely affect the further work of the chainsaw.

In some models of chainsaws, to ensure the operation of the fuel pump, special hoses are installed, which transmit the air pulse from the engine crankcase to the fuel pump of the carburetor. If this hose is overwhelmed, the saw will work unevenly at idle and will not work under load at all.

Husqvarna 137 and Husqvarna 142 household owners with any deviations of the engine from the norm, first of all, check the pulse hose, t. to. This is considered the most common cause of the breakdown of these chainsaws.

Checking the spark on the spark plug and the gap between the coil and the magneto

The sparkling candle is the most important detail that is responsible for ignition of the fuel mixture fed into the cylinder chamber. If the candle has served its own, then it will give out a weak spark or not to give it out at all. This can be checked in the following way:

If the spark arises constantly, then this indicates the serviceability of the candle. over, not only the candle is working, but also the ignition system. the coil and the high.voltage wire. If a spark on a candle occurs, but with interruptions (intermittently), then such a detail must be replaced. You must first check the gap between the contacts. The size of the gap should be from 0.5 to 1 mm.

For each chainsaw model, manufacturers indicate the recommended gap, so you need to use the directory. You can measure the gap with a special probe or a sheet of paper folded several times.

The absence of a spark on the candle indicates a malfunction of the ignition system, so before replacing the part, you should make sure that the ignition coil and a high.voltage wire should be serviceable. Not to start a chainsaw may be due to clogging of the electrodes of the candle. The presence of a black carrier on a candle or wet electrodes. all this can indicate the following faults:

• Black Nagar. the carburetor of the chainsaw is adjusted incorrectly. The incoming mixture in the cylinder has a lot of fuel and little air. You can eliminate the malfunction by cleaning the soil on the electrodes of the candle with subsequent adjustment of the carburetor
• If the candle is wet (poured), then this may indicate the following. either the ignition system (including the candle itself) is faulty, or an excessive amount of fuel enters the cylinder, thereby the candle is poured. First you need to make sure that the candle gives a good spark, and only after that adjust the carburetor. It is not recommended to dry the wet candle by calcining, so it should be wiped dry dry, and then let it dry in the sun
• If the candle has a red or pink carrier on electrodes, then this suggests that the gasoline used contains a large number of additives. Typically, this effect gives gasoline of the AI-95 brand and above, an increase in the octane number in which is achieved by adding additives

When the candle has a brown color (brick), this indicates not only a properly adjusted carburetor of the chainsaw, but also about the serviceability of the ignition system. If a new spark plug is used, which gives a weak spark when checking (or there is no spark at all), then this is a sign of a malfunction of the ignition coil. The coil must be replaced with a high.voltage wire.

It is interesting! Check the size of the gap between the ignition coil and the magnet. Different manufacturers of chainsaws indicate the recommended gap (usually the value is 0.25 mm), if this value is higher than the norm, then it should be adjusted using the probe.

Chainsaw simplifies many operations. However, for a long time, it cannot demonstrate its initial level of work. Therefore, at a certain moment, problems may occur. Naturally, the owner can eliminate some malfunctions independently, but in any case there is a risk that he will incorrectly determine them, and this is fraught with the fact that by his actions he can completely disable the tool. Therefore, it is advisable not to show the initiative, but to entrust this work to a specialist.

Starts and stalls

If the chainsaw is started, there is a spark, but the functioning for unknown reasons is not carried out in the future. There are two main reasons:

• Improper brake of the chain leading to its jamming. It is necessary to check the amount of oil in the tank and the quality of the pipe along which the fuel flows to the lubricant. The part due to frequent work may break, clogged with dust. In the operating instructions, manufacturers always persistently recommend checking the chain, other tool channels even for preventive purposes, and not only when there is already a fact of breakdown.
• The chainsaws do not start, stall due to incorrect carburetor operation. With a simpler breakdown, it is enough to clean the device, rinse it, dry it. In the worst state of affairs, you will have to purchase a new carburetor. You can repair the part independently. the sequence of necessary work is often indicated by the manufacturers in the instructions for operation.

Thanks to the article, everyone will be able to figure out why the chainsaws are not started, the causes and ways to eliminate malfunctions. The main thing is not to make spontaneous decisions, not to violate the operating conditions, to first look into the instructions that may be a good assistant. If it was possible to determine the reason why the chainsaw of friendship or other model does not start, but there is no certainty that it will be possible to solve the problem on your own, you need to contact the master.

Sapuna check and cleaning it.

Sapun is another element, from the incorrect operation of which the chainsaws may not start or stall during the sawing process. This element is located on the fuel tank cover in the air opening area. This is a kind of valve that does not allow gasoline and leveling air leveling, which is necessary for the free flow of fuel into the carburetor.

In the case of a bursting of the soundtress, the working chainsaw stalls, and when starting it refuses to start. The thing is that air ceases to flow through the hole. As a result, a negative pressure (vacuum) is created inside the fuel tank, which prevents the flow of gasoline by the carburetor.

Determining the problem is quite simple. Disconnect the fuel supply hose from the carburetor and see what is happening with gasoline. If it strates freely with a good stream, then everything is in order with the off. In the event of its absence or it flows weakly and intermittently, the reason is identified. the sapun is clogged with dirt. You can solve the problem with cleaning the air opening with an ordinary needle or a powerful stream of compressed air.

Sapun check

Sapun is that detail about which some owners of the chainsaws do not even know. However, it has a significant impact on the work of the tool and supports it in good condition. The saapoon is located on the lid of the fuel tank. in the place of the opening for air circulation.

This element performs valve functions and is responsible for two tasks:

The pollution of the saapun leads to the fact that the chainsaws are constantly stalling when sawing. At the time of starting, the tool may not start elementary. These consequences are associated with the lack of air-due to blocking the hole through which it passes. As a result, the tank turns into a vacuum that blocks gasoline access to a carburetor.

To recognize this problem, you need to perform such actions:

• The fuel supply hose is disconnected from the carburetor.
• Analysis of the state of gasoline is carried out: if the fuel continues to flow with a flat stream, then the sapun is in good condition. The uneven movement of the fuel indicates the clogging of the sapun with mud particles.
• The saapun is cleaned by means of a needle or jet of compressed air.

Diagnosis of graduation channels

The clogging of the exhaust channels or their silencers is another unobvious cause of the non.working state of the chainsaw. In addition to problems with starting, clogging of channels manifests itself in the drop in the power of the tool. Graduation channels are subject to accumulation of tarry deposits. They focus on sparkles or muffler channels. The reason for the formation of these deposits is the use of poor.quality gasoline or oil. These components do not allow the tool to remove exhaust gases.

With the repair of the exhaust channels, the owner of the saw is easy to cope on your own. The only difficulty is in the depths of the location of this part. To get to it, you need to represent the structure of the saw well.

The instruction consists of several stages:

• The silencer is removed (for this you need to unscrew the screws).
• The cooling panel and end seal are extracted.
• The sparking is extracted.
• The resonator case is disassembled.
• Elements are laundered from the carbon with a cleansing solution.
• The elements are thoroughly dried.
• The saw is going back.

In the process of disassembly, it is easy to make imprudence and allow sand entering the cylinder. To prevent this from happening, it is important to first close the exhaust channel with a sterile cloth.
