New chainsaw does not start Hunter. Determine the presence of fuel and its supply.

Why not starting chamber chainsaw

Without tools in the country or private farm today cannot be. This is known to every real estate owner in the city or beyond. To prepare logs and create outbuildings, you need a saw, ax or chainsaw. The latter is often bought by electric models for the reason that it is not tied to a power source. However, units of gasoline differ in weight and configuration, so the definition of choice can be quite complicated.

If you have not yet decided which version of the equipment to purchase, then you should understand where the device will be used. The weight and power of the chainsaws are designed for various applications. Manufacturers supply three groups of tools to the market, each of which copes with the tasks, so it is important to determine what work you will perform on the site using a chainsaw.

For small garden work, low.power chainsaws belonging to the amateur class are suitable. It is intended for the periodic mode of operation, which does not exceed an hour a day. On the market you can find a semi.professional tool that can help even in the construction of the house. If you are only at the initial stage of construction, it is recommended to buy just such a chainsaw, the weight of which can be about 6 kg.

With a professional saw, you can even demolish the forest. With this manipulation, the saw will work during a round day. If you still cannot decide which device to purchase, you should stop focusing on the Huter BS-45 chainsaw, which will be considered below. His

Description of the BS-45 chainsaw

If you need a chainsaw, you should pay attention to the model mentioned above. It works at the expense of the engine, the power of which is 2.3 liters. from. The tool is designed for domestic use, for example:

The chain saw has a chain brake, which provides safe operation. The manufacturer took care of the availability of 45-centimeter tire. Among other things, the chainsaw has an anti.vibration system.

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.

The chainsaw is poorly started on the cold

Violation of the sequence of actions when starting to cold

If a new chainsaw is not started to cold, then the reason may be in the wrong sequence of engine start. As a rule, each manufacturer in the instructions for the chainsaw indicates the procedure for the start of the chainsaw to the cold. It is mainly similar to all two.stroke internal combustion engines that are installed on the chainsaws, and is the following procedure.

• Closing the air damper (it is necessary to enrich fuel during starting).
• The fuel suction using a special primer for this (on some models of chainsaws, the primer is not provided for by the design, and therefore this item is absent for them).
• Turning on the ignition (if you forget about it, then you can mistakenly calculate the tool faulty).
• To carry out several starter movements to the first “outbreak” of the engine (it is important not to miss this moment, otherwise it is possible to “fill” the engine).
• Set the air damper to the position openly.
• Start the chainsaw engine.

Fuel problems

As in the option of difficult to start hot, problems in the fuel system can affect the launch or not the opportunity to produce it and on the cold. Adjusting the carburetor, contamination of the fuel filter and the highway, all these are the reasons that cause difficulties when starting.

Diagnose the fuel system, this is the first thing that needs to be difficult for the cold.

It is worth paying attention to the quality of fuel, t.to. When using a mixture of gasoline with butter, in which there is a small amount of water, it may be much difficult to start or become impossible.

The mixture must be used fresh enough, t.to. When storing oil diluted with oil for more than a month, its properties are lost and complicates the launch, both on the cold and on a hot engine. Gasoline for this reason can burn poorly.

Malfunctions in the engine

ZPH dumbings, sticking of rings, wear of the CPH, air leaks through seals and gaskets, lowering compression, all these problems can make the chainsaws impossible or significantly make it difficult to make it difficult. For example, with not significant wear of CPH, compression in the engine is reduced. In this case, the launch on the “cold” will be much difficult, or the saw may stop starting, and “hot”, the tool will start well.

It is quite difficult to accurately diagnose problems in the engine in its launch problems, and it will be better for this to turn to a specialist in this field.

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.

Fuel supply system and its repair

If you are faced with a problem that is expressed in the fact that the fuel does not get into the cylinder, then this can happen due to filter pollution. To solve the problem, the fuel hose is removed, which will allow you to check how the fuel flows. Filter cleaning is required if the stream is quite weak. It should be removed or replaced with a new.

Fuel filter replacement is carried out every three months. Fuel may be absent or present in insufficient quantities. The reason is the clogging of the air filter. When the air stops entering the carburetor, engine operation is disturbed. The filter should be removed, cleaned in water, and then dried and installed in place.

The chainsaw is not started? Reasons and solutions

Basils have long been a kind of innovation and even more so are not considered exclusively a professional tool, because today literally every owner has such a universal device in his tools. And although there is a huge variety of types and models of chainsaws, in general, their designs do not represent something particularly complicated. With proper use and maintenance of this tool, any problems with its work arise quite rarely. But what to do if a chainsaw does not suddenly start? The main thing is not to panic and in order to figure out what is the reason for the problem.

First you need to check the fuel level. If it is not enough, it is necessary to correctly prepare the fuel mixture, which should include the proportion of gasoline/oil indicated in the operation instructions (the oil brand is also indicated in the instructions). To prepare the mixture, use AI-92 gasoline correctly-this will get rid of many unnecessary problems. The amount of the mixture should be designed for 1-2 weeks of the chainsaw, t.to. gasoline has a feature of losing its octane properties.

The tool may not start because during its launch flows a candle of ignition. If this is true, then to solve this problem, it is necessary to turn the flooded candle and be sure to dry it (without pumping), drain the fuel from the candle hole and make a half.hour break. Then install either dried or spare candle in place. It is also important to pay attention to the contact between the tip of the candle and the high.voltage wire.

The completely dry light of the ignition suggests that the fuel mixture does not occur, which means that there is a certain problem with the carburetor. First you should clean the fuel filter. If after eliminating all available pollution, nothing has changed, it is necessary to do a carburetor. However, it is better to entrust its disassembly and cleaning to specialists in this matter.

If there is a spark, but the chainsaws still do not start, you will need to additionally check the air filter and the saeph. Air filter is easily cleaned of dust. In order to check whether the sapphone has clogged for leveling the pressure in the gas tank, it is necessary to disconnect the fuel hose and see how the fuel flows from it. If the stream is normal. the saopant is in order if there is no fuel or it flows very slowly. you need to clean it.

New chainsaw will not start

Often a completely new chainsaw cannot be launched the first time. With a cold launch of its engine, the switch is installed so that the damper is closed. Now you need to pump up the fuel into the carburetor, and then twist the launch hand well. It is considered normal, even if after 2-5 launches the tool starts up, but stalls. After that, you can transfer the switch to the position of half.gas, and then to the working position, and continue to start the chainsaw.

The reason that after the winter period the chainsaw refuses to work, it may be elementary. the fuel mixture has decomposed and lost its properties. To eliminate this problem, it is necessary to pour the old fuel, unscrew and dry the spark plug, season the chainsaw with a new fuel mixture and abundant the engine several times. After installing the candle in place and in the absence of other problems, the chainsaw will necessarily start.

The chainsaw is not started. Why? Reasons and how to avoid.

You don’t have a chainsaw? Often this can happen at the most inopportune moment when you need to urgently work. Agree that this is unpleasant. I must admit that the chainsaws from eminent manufacturers (STIHL, Husqvarna, Echo, Solo and others) do not start much less often than from Chinese manufacturers. Today we will analyze the reasons for this unpleasant event and measures how to avoid this. If you do not find your reason among the listed, you can ask a question in the discussions.

To begin with, you need to decide on the new chainsaw you will not start or it is already in operation for a long time. This is necessary to choose measures to correct the malfunction.

If you do not start a new chainsaw, then:

• If you have not passed 14 days from the moment of purchase, you can pass or exchange the purchased chainsaw. This is the most reasonable way out of all. (When buying a chainsaw, be sure to ask sellers to start it. This does not apply to online stores, since serious ones always check the goods before sending the buyer.)
• If the chainsaw is not possible for objective reasons or more than the spirit of weeks has passed since the purchase, then the reasons are most likely serious enough. To be sure that the chainsaw is not started for technical reasons, and not by oversight. carefully study the instructions.
• Next, we will consider the reasons why the chainsaws may not start which are suitable for both new chainsaws and the former.

We will analyze the reasons why the chainsaws may not start in the order of the sequence of verification.

• Check the presence of fuel in the tank and its quality. It is logical that the chainsaws will not start without fuel. Therefore, if there is no fuel, then pour. If the fuel remains in the tank for a long time (more than 3 weeks), then drain it and pour a new. Unstimately stored fuel with oxygen access quickly loses the octane number and becomes unsuitable for the work of a chainsaw on it. Read more about fuel here: how to dilute gasoline for a chainsaw? Oil selection, proportions
• Check the spark plug of the chainsaw. First, whether it is flooded or not. If wet. wipe, blow out and screw in place. Secondly for the presence of a spark. This can be checked by twisting it and putting it on the tip, put on the cylinder block and pull the starter cord. If there is a spark, then we go further for reasons. Thirdly, look at the condition of the candle. Read more about how to diagnose the operation of the chainsaw by the state of the candle here: Diagnosis of the chainsaw engine as a candle state.
• Check air and fuel filters. Heavy filters can interfere with the launch of the chainsaw. The air filter is located immediately under the cover of the chainsaw. Fuel is in the tank. Also check the bacon that is also located in the gas tank. For diagnosis, it is best to remove them and try to launch it without them.
• It is necessary to inspect the silencer for the presence of a carbon in it. Read more about cleaning the muffler here: Cleaning the muffler of the chainsaw.
• Inspect all hoses and connections. Often a loose connection or crack in the hose becomes the reason that the chainsaw does not start. It is also necessary to inspect the crankshaft oil seals.
• Clean the carburetor. It is best to disassemble the chainsaw carburetor on a free table, laying out pure matter. Lay out all spare parts separately in order to facilitate the assembly. You need to clean the carburetor with special liquids for cleaning nozzles and injectors, for example.
• Check the ignition system. Could go off the angle, the flywheel.
• If the previous measures did not help and the chainsaws are still not working, then the carburetor adjustment may be required. Adjusting the carburetor of any chainsaw is similar to the material above the link above. The only exception is the stihl chainsaw, which have only one idle speed adjustment screw.
• The most unpleasant situation is when not one of the measures above did not help. Here you may need to replace the CPG (cylinder-piston group). This can be checked in three ways: 1.If the piston does not move in the cylinder, then the CPG is definitely better to change. You can certainly put a new piston, waste the cylinder, but this will not give the same result as in the case of the installation of a new CPG. 2.Disassemble a chainsaw and conduct a visual inspection. 3.Remove the muffler and inspect the visible part.

There is no spark on the chainsaw of Stihl 180

The main malfunction, due to which the chainsaw of the Stihl MS 180 is not started, may be the absence of a spark between the electrodes on the spark plug. Signs of this malfunction can be detected if you unscrew the candle and inspect. Having discovered when examining that the candle is wet, it is necessary to proceed with the search for the reason for the absence of a spark on the spark plug.

The spark plug is faulty

The first thing to do is to check the performance of the candle.

It is quite easy to do it. The candle is inserted into the cap of the high.voltage wire and pressed to the engine cylinder, after which the starter moves several times if the spark is not observed between the electrodes, then it is faulty or faulty of the ignition module.

Checking the sparking candle is carried out with the ignition on.

In order to find out for sure that the problem is in the light of the ignition, it is necessary to check the obviously serviceable similarly. If the spark appeared as a result of checking, then the problem was found and replace the candle with a new one to eliminate the malfunction.

Problems with ignition coil

The ignition coil, it is also called the module has a non.graceful design, therefore it is very difficult to determine its performance without a special tool. If the spark on the working candle has never appeared, there is a suspicion that the reel is to blame. But do not immediately take off the old coil and run to the store, problems can have a slightly different character.

There is no gap between the flywheel and the ignition module

In some cases, the absence of a spark on the spark plug is explained by the wrong clearance between the contacts of the ignition module or flywheel. It may be larger, and it may also not be at all, and then scratches that were formed as a result of contact with the contacts of the coil will be observed on the surface of the flywheel.

Check and set a gap without a special tool. you can. To do this, you need to remove the starter, weaken the two screws of fastening the coil and laying the plate cut out of the plastic bottle between the contacts of the flywheel and the ignition module, tighten the screws of the module mounting.

If, after such adjustment of the gaps, the spark appeared, everything is in order, you can continue to work with the chainsaw of the Stihl 180, if not, you need to re.examine and check if the flywheel will touch the coil contacts again. Suppose as a result of the audit found that after adjusting the clearance, it was gone again. So the reason is most likely in the crankshaft bearings.

Defective crankshaft bearings

With a defect in the crankshaft bearings, a small backlash is observed on it. Check the presence of a backlash you can with a stroke of the flywheel of the chainsaw of Stihl 180 from side to side. If there is a backlash, then under the influence of its magnets, the flywheel is attracted to the contacts of the ignition coil, t. to. The backlash on the bearings allows him to do this and as a result the spark disappears.

Replacing crankshaft bearings

Replacing crankshaft bearings is better in a specialized service, t. to. When replacing, you need to completely disassemble the Stihl 180 chainsaw and remove all its main nodes.

Without a certain experience or at least the skills of repairing similar chainsaws, to replace the crankshaft bearings qualitatively, it will not work.

So, we figured out the lack of a spark, but what to do if there is a spark, and there is no answer to the question why the chainsaw of the Stihl 180 is not started. The reason can be hidden in the fuel system.

Recommendations of Profi for the control of the working mixture

If the verification of the proper result was not given, we proceed to checking the ignition. A wet candle of wet indicates an excess of fuel and a lack of air, the mixture, which during launch flows a candle, cannot set fire to a powerful spark in such a proportion.

For the output of the quality and amount of the airborne mixture to the optimal parameter, a wide range of operational adjustments is used. The cause of fuel overflow in old chainsaws may be the leature of the fuel consumable crane and the float valve of the carburetor.

In standard situations, after a short purge of the cylinder, with a candle removed or turned on, the normal start of the launch is completely restored.

New chainsaw is not started.

I purchased a HUTER BS-45 saw in the online store. Instructions about nothing. Written how to attach the tire and pull the chain. Diluted gasoline 92nd with mineral motor oil from the car 1:20. I turned on the ignition in position I, pulled out the suction, pumped up gasoline. Twisted for half a day, not a single flash. And without suction and with ledge. I twisted the candle, wet, in a black raid, so the engine worked before me, so I am doing something wrong? I leaked gasoline and diluted a new mixture of 1:40, washed the candle with gasoline, scooped it over the gas, screwed it hot into the engine, in the hope that gasoline will evaporate from a hot insulator. But again, not a single sneeze. Flies a candle decently, sometimes even gasoline is in the gap between the electrode and the contact. There is a spark on the twisted candle. I arrived home, read about the purpose of the fuel screws. What do you think it is worth trying to twist the screws tomorrow, impoverish the mixture (there is no more control of regulation, I put it right even by the sound) or take it to the service center? Go 60 km during working hours through the whole city, I don’t really want to.

And this is. I, of course, full losara regarding purchases in online stores. But if you buy something there, then I think you need to stipulate the verification of the goods with you. Otherwise-go forest, online stores! Means so. Try to twist the candle, twist the engine with the starter a couple of times, let the file stand. Then screw the candle and try to start without closing the air damper. If this does not give results, try to replace the candle with a knowingly working. Either zero from a normal store, or obviously working on another saw or spit.

Search for reasons why the chainsaw is not started

Amateur and professional chainsaws are difficult to devices. Motor resources of their two.stroke engines, components and assemblies have its restrictions. For this reason, quite reliable and expensive tools along with cheap Chinese units periodically fail and refuse to start. The situation when the chainsaw does not start or stalls is not very pleasant and sometimes puts the user at a dead end. How to determine and eliminate the malfunction, returning the tool to the tool.

For this reason, quite reliable and expensive tools along with cheap Chinese units periodically fail and refuse to start.

The situation when the chainsaw does not start or stalls is not very pleasant and sometimes puts the user at a dead end. How to determine and eliminate the malfunction, returning the tool to the tool.

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.

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.

Determine the presence of fuel and its supply

First you need to make sure that there is a fuel mixture in the tank of a chainsaw that does not want to start, and it regularly enters the carburetor. With a full tank, we check how the mixture is supplied to the gas pipeline.

Disconnect the pipe of the fuel system from the carburetor and try to swap. In case of full order, when pumping, gasoline will be supplied with jerks in accordance with the norms specified by the manufacturer.

Weak fuel supply or its absence can be a consequence:

Often the reason for the poor launch of the chainsaw may be too complete tank. In this case, it is worth paying attention to the presence of subtexts under the cover of the saw card. If they are present, see the connection of the gas supply tube with the carburetor. Most often, it is squeezed out by pressure when twisting the cover of the tank, tucked under the neck, which prevents the engine from starting.

The quality of the fuel mixture can also become one of the reasons why the chainsaw is not started.

If after performing the work, do not drain the remnants of gasoline, and leave the tool for long-term storage (more than 2 weeks), then the processes of resounding and polymerization of the components will begin to occur inside the tank.

What can cause a carbon for the piston, rings and a cylinder sleeve. Therefore, always before work, prepare the mixture only in the required amount.

Checking the state of fuel and air filters

If everything is in order with fuel quality, the chainsaw engine may not be started, due to the clogging of fuel and air filters. To diagnose these elements, you will need to make a number of manipulations associated with their dismantling.

With weak pressure or its absence in the pipe, the filter should be disconnected. Before that, free the tank from the mixture and remove the filter element itself. Dismantling is carried out by means of a wire hook.

The clogged replaced cartridge causing poor the gas station engine is to be cleaned, but it is best to change it to a new.

Not a chainsaw is started. the reasons for poor work for cold, hot

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.

Why is the chainsaws badly starting

• fuel and air filters;
• reduced compression;
• carburetor adjustment;
• spark plug;
• ignition coil;
• gap between the ignition coil and the flywheel;

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.

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.

Violation of the sequence of actions when starting to cold

If a new chainsaw is not started to cold, then the reason may be in the wrong sequence of engine start.

As a rule, each manufacturer in the instructions for the chainsaw indicates the procedure for the start of the chainsaw to the cold.
