The chainsaw does not start, there is a spark. Why the chainsaw does not start: causes and solutions

When your chainsaw does not start, although you are doing everything right, it is puzzling.

However, do not rush to carry it in for repair - the reason may not be so serious and it is possible that you can completely cope with the alleged malfunction with your own hands.

You can find a solution to why a chainsaw is difficult to start on a hot one in the instructions.

If for some reason you don’t have it, then we will talk about the device’s device and possible problems in the first part.

If you are doing everything correctly, according to the instructions, but the chainsaw still does not start or stalls, then the second section will help you, where you will learn about the most common solutions to this problem.

The most popular and frequently used chainsaw models by Russian users are Ural, Husqvarna, Shtil 180 and Partner.

Although they have their own characteristics, they are generally similar, so we will describe the possible causes of breakdowns and how to eliminate them in general for all tools.

Saw device - determine the location of the problem

All chainsaws are more or less the same. This applies to both foreign-made devices (Husqvarna 142, Makita, Shtil 180, Partner 350) and Russian (Ural, Druzhba).

Therefore, you can easily find the answer to your question why the chainsaw does not start or why it stalls.

Below you can see a photo of the Partner 350 chainsaw.

Most often, problems in chainsaws occur with the following elements: fuel, lubricants, air, spark.

During operation, these elements interact, and if one of them is broken, then this can be the reason why the chainsaw does not start.

All these 4 elements are located in different areas cars: the carburetor is responsible for the air-fuel mixture, lubrication is obtained by adding gasoline, air enters a special air filter, and the quality of the spark depends on the ignition unit.

It is worth starting with the fact that all chainsaws start up differently - hot and cold. On the this moment There are 2 most commonly used mechanisms that are responsible for this process.

First of all, let's look at the instructions. Often it says that when you turn on the chainsaw, it must be with the emergency stop brake engaged.

It is suggested that you do this for safety so that you do not injure yourself with the tool. However, starting the chainsaw in this position is much more difficult, so it is best not to lock the brake.

The chance of you hurting yourself is minimal, even if you have little or no experience with this tool.

According to the instructions, inside the chainsaw body there is a fuel tank and an engine, and on the outside there is a handle, a starter, a tire with a chain (saw part).

When they say that the saw does not start, the following may also be meant: it starts, but immediately stops working, loses power or cut quality.

Most often, interruptions in the operation of the saw are in the operation of the engine, but it is not recommended to analyze it immediately - it is better to start looking for the problem gradually, from the simplest.

So, first of all, pay attention to the fuel - if its composition and method of preparation are not suitable, then even very reliable tools, like Husqvarna 142 or Ural, will not work.

The correct fuel mixture is prepared only from gasoline, mixing it with special oil, the brand of which is always indicated in the instructions for the tool.

The problem of oil can be not only in improper preparation, but also in too long use - if it has been in your canister for months, it will certainly deteriorate, the same fate will await your chainsaw.

Another common problem is that the spark plug may be flooding while starting the tool.

Inspect the spark plug - if it is completely dry, then something is wrong in the system. Maybe fuel is not getting into the cylinder.

Also, upon examination, you can see black soot or too a large number of fuel - this all indicates improper adjustment of the carburetor.

If the saw starts, but immediately stalls, then the problem is most often in the fuel filter or carburetor jet - they are probably clogged and therefore do not work well.

To exclude a saloon from damaged objects, you need to disconnect the fuel hose attached to the carburetor and check if fuel is flowing from it.

When working correctly, gasoline should flow from the device in a stable and dense stream.

If the saw does not start hot, stalls after being turned on, or quickly loses power, then you need to inspect the muffler.

If the problem is in it, then it will be clogged with deposits left as a result of the exhaust, which is bad for the operation of the chainsaw.

A common cause of chainsaw failure is a small amount of chain lubrication. - This may be if the channels of the tool are clogged or the oil line is leaking.

It is also necessary to inspect the places where the pipes are connected to the oil pump fittings - it is possible that they are leaking.

The material below describes the main malfunctions of the Druzhba chainsaw.

The most a difficult situation occurs if the breakdown is somewhere in the cylinder. This requires a simple visual inspection.

If during it you find that a chip or unevenness has formed on the device, then the problem has been found.

How to fix a chainsaw

Measures needed for recovery correct operation saws, no matter if you have a Ural or any other model, depend on the location of the problem.

Please note that not everything you can fix with your own hands - if the breakdown is serious, then the saw will have to be carried to a specialist.

If you have done the first step - checked and corrected the quality of the oil, but the device still does not work, then you can move on.

If the problem is in the candle, then it is also quite simple to solve it - you need to turn out and dry the candle, but do not pierce it, because. this will destroy the candle.

Excess fuel that is inside should be drained through the hole. You need to dry the candle for at least half an hour, then insert it back and try to start the tool again.

In addition to pouring, it may be that the candle has simply become unusable.

In this case, it is good to have a spare part (or rather a set) to replace this element and delete it from possible causes device breakdown.

In addition to the candle itself, the reason that the chainsaw is difficult to start hot or stalls may be a bad contact connecting the end of the candle and the high-voltage wire.

If everything is in order with this place, but there is still no spark, the ignition unit may have broken. You cannot fix it - you will have to replace it with a new one.

From time to time it is necessary to clean the air filters in chainsaws. If you have never done this before, then the reason for the breakage of the tool may be that it is clogged with dust.

If you have a Stihl 180, Partner 350 or Ural chainsaw, check the saloon first. A common cause of incorrect operation of these models is its clogging.

You can clean the saloon with a sewing needle - there is nothing complicated about it.

Another point that sometimes worries owners of Stihl 180 chainsaws is frequent idling after the first tanks of gasoline have been used up. However, according to experts, this is not a problem at all.

But if the phenomenon is still disturbing, then you can reduce the engine speed with the carburetor screw.

The video below shows how the Stihl chainsaw is repaired.

You can also clean the muffler on your own - this is not only a problem for Stihl 180 or Husqvarna 142 chainsaws. Domestic Friendship and Ural can also stall because of this problem.

The problem of poor performance of chainsaws often lies in the carburetor, but it may not work to fix it yourself, without experience in this matter.

Therefore, if you have not done this before, give your saw to specialists. Trying to save now, as a result, you can overpay many times more if you accidentally damage some important part.

If you have done all of the above, but the problem still persists and your chainsaw stalls or does not start, then the problem may lie in the cylinder group.

If chips and damage were found on the cylinder or piston assemblies, then these elements will have to be replaced or the cylinder must be bored for a new piston of a suitable size.

If you inspect the chainsaw tubes and see that they are leaking, this means that the problem with your chainsaw is insufficient chain lubrication.

To remove this problem, you need to replace the tubes and carefully seal the places where they connect with sealant.

It may also be that the parts that your saw is equipped with have reached the end of their useful life. In this case, you will have to change them to new ones.

You can see the service life of the components in the instructions.

Stihl 180 is one of the most common chainsaw models, so let's talk about its problems in more detail.

The most common reason why the Stihl 180 saw does not start or stalls is the carburetor is clogged. In this case, it will have to be cleaned. The second most common problem is a clogged fuel filter.

It will have to be changed if it fails.

Replacing the spark plug is also a common solution to problems with the Model 180.

Look also at the condition of the pistons - perhaps they, as well as the cylinder and seals, need to be replaced.

In general, the Calm 180 model is quite durable and, most likely, if it does not start or stalls, then the problems in it are not too serious and you can fix them yourself.

The video below shows the repair of the Ural chainsaw carburetor.

Almost the same can be advised regarding the Partner 350 and Husqvarna 142, Ural, Makita models.

First of all, check the air filter - it could be clogged with sawdust and other debris. Then inspect the carburetor (in Partner 350 it is located in the same place as the candle).

The main advice in repairing a chainsaw with your own hands is not to do something that you do not know how, because. this can only make the situation worse.

If the chainsaw does not start, stalls or does not work well, then check first of all the simplest and most easily accessible elements: perhaps the oil is not properly selected, or it fills the candle, the filter is clogged or the pipes begin to leak.

All these problems are easy to fix with your own hands.

In case of serious breakdowns, if you do not have the necessary qualifications, it is better not to try to do repairs yourself and entrust the work to a specialist.

In any case, the elimination of a breakdown, even by proxy, will cost you less than a new model.

Do not forget to also check the instructions for the tool and replace all the parts responsible for its operation in time.

This will help you not to puzzle over why the tool stopped working and not waste time parsing and checking it.

If you still cannot do without repair, then before you start work, watch a video on how to disassemble and repair a chainsaw - it will help you.

1. "Running" STIHL chainsaws

It is categorically impossible to run in a new Stihl gas tool: after the so-called "running in", the Stihl chainsaw is usually carried to the service. For Stihl motors, idling is generally not desirable. The fact is that in 2-stroke engines at idle, incomplete combustion of the fuel mixture occurs and the engine cokes. The advice is simple - give the chainsaw gas all the time, t STIHL machinery loves to work! The only limitation for new chainsaws is that for the first 2-3 tanks, do not give full throttle, let all the parts of the saw grind in at medium speeds. However, if the saw is "stuck" in the log - go full throttle, this is normal.

2. Air and fuel filter

It’s just some kind of mysticism, but very often even experienced motorists for some reason forget that the chainsaw has a standard 2-stroke internal combustion engine that needs fresh air and fuel. Surprisingly, many users do not change air and fuel filters for years! And only thanks to the unique design of STIHL engines, they work for a long time on a dirty fuel mixture (which is very important in forest conditions and lack of service nearby). However, miracles do not happen, and a dirty fuel mixture eventually kills even ultra-reliable Stihl engines. And replacing the engine is usually half the cost of the saw. At the same time, other spare parts “stretch” behind the engine, which makes repairs unprofitable. Therefore, after each work, open the filter cover (it is very easy for Stihl) and check the filter. Most Stihl filters can and should be washed. Pay special attention to the inside of the filter, which goes into the bypass air manifold: everything should definitely be clean there. If a not possible to clean - change! To do this, always have a reserve. The fuel filter works, as a rule, much longer. But don't forget to check it too. If the saw does not start, the fuel filter may be clogged with dirt from low-quality fuel.

3. Filled candle.

This is a "disease", as a rule, for novice users of gas tools. As you know, for the plant of a cold chainsaw, it is necessary to pump fuel into the system. To do this, the user must, with the throttle valve closed (so that the mixture does not ignite and burn out), vigorously pull the starter cord several times until the first "burr". After that, you can start the saw at high speeds with the throttle open. So, many beginners either miss the moment when the saw “grunts” for the first time or pulls sharply enough (then the saw does not “grunt” at all) and continue to turn the starter, while simultaneously supplying fuel not to the system, but to the combustion chamber. In this case, the fuel mixture fills the candle and the saw will no longer start. So this is the advice. Firstly, on a closed damper, you need to pull about five to seven times, a maximum of ten, and even if you don’t hear the first “burk”, open the damper and try to start the saw (switch position “half-open damper - high speed”). Secondly, the sharper you pull, the faster you will start the engine.

If you filled a candle, then you can start the saw as follows. Unscrew the candle, wipe it with a dry clean cloth. Turn the saw upside down with the spark plug hole down and turn the starter several times until all the fuel is squeezed out of the combustion chamber. Screw the dry spark plug back in and try to start at high speeds in the switch position - "half-open damper".

4. STIHL fuel oil

The fourth most common reason for a saw to be repaired is improper handling of fuel oil. A 2-stroke engine, as you know, requires the addition of engine oil to gasoline, which serves to lubricate rubbing parts, primarily the piston in the cylinder. Remember, only Calm has a proportion of engine oil of 20 g per 1 liter. All Chinese chainsaws have a proportion of 40-50g per 1 liter (here, by the way, is an easy way for you to determine the original from a fake: just ask the seller about the proportion of oil in the fuel mixture). When oil is overfilled, it does not burn out, which is deposited on the walls of the piston, and when underfilling, friction between the piston and cylinder increases. Those. in both cases, premature wear of the cylinder and piston occurs. Of course, you need to strive for the ideal proportion, but a couple of percent in any direction will not lead to a sad result. For the preparation of the fuel mixture, a special liter canister, offered by Stihl. Look, it is really very convenient to prepare the mixture with its help.

STIHL chainsaws, by the way, do not have the concept of cylinder repair, the entire engine is being changed. Therefore, if the cylinder has already been worked out, replacing the piston with rings has no effect: in just a few hours of operation, perfectly round rings and a piston are developed to fit the worn cylinder oval. And that's it, goodbye compression. We are not talking about the use of non-branded oil at all, although there are still some desperate ones who, for the sake of penny savings on cheap oil, do not regret several thousand spent on a branded chainsaw. Some of them are even lucky - they get on oil with similar properties, like STIHL. But rare luck only confirms the rule - you need to use only branded oil.

5. Drive sprocket

Also a mystical spare part, which most users for some reason forget to change. And although when changing the chain it is very clearly visible that the teeth of the sprocket have a groove in the form of grooves, very often the sprocket is used "to the last": until the teeth are developed so that the chain no longer clings. It is not difficult to remember that the wear rate is no more than 0.5 mm of the furrow depth. Otherwise, a heavily worn sprocket will stretch the chain until it is completely impossible to stretch it. As a result, you will always buy new chains and throw them away after 2-3 sharpenings, i.e. practically new. Remember, with proper use of the STIHL chainsaw cutting headset, when two chains are completely worn out, one sprocket wears out, .

Question: During operation, the stihl ms 180 c chainsaw stopped idling and stalled. With difficulty started, but again stalled at idle.

After that it doesn't want to start. The next day, after unsuccessful attempts to start, removed and washed the air filter. It did not help, I had to remove the candle - it turned out to be dry, although there were plenty of attempts to start it.

I cleaned the breather with a needle (it was not clogged). Changed the fuel filter (although the old one is not visually dirty). I cleaned the carburetor and put in a new spark plug just in case. The saw won't start! Pulled the spark plug again and it was dry. What to do?

Answer: Remove the muffler. Look at the piston, if it has longitudinal stripes, then replacement is required.

Question: What is the difference between the drive and chain sprockets of the Stihl 180 chainsaw?

Answer: There is no difference between the "drive sprocket" and the "sprocket wheel", it is different names the same detail.

Question: I bought a chain saw Stihl ms 180, I really liked it, but I want to ask you if my saw can cut a thick tree?

Answer: The standard length of the MS 180 bar is 35 cm, it is possible to saw a log of 70 cm in diameter, if logs of this diameter predominate, then you need a chainsaw with more power.

The MS 180 will, of course, cope with the task, slowly and surely cut all logs of large diameter, but you need to remember that by giving heavy loads to a machine that was not designed for this, you (at best) reduce the life of the chainsaw, that is
approaching its overhaul.

Question: Can you please tell me if a 45 cm bar can be used on a Stihl 180 chain saw?

Answer: The MS 180 chainsaw can be fitted with a bar with a maximum length of 40 cm.

Question: Where is the breather in the Stihl ms 180 chainsaw?

Answer: valve ventilation system("breather") is located "on top" of the gas tank and oil tank, not visually visible, because everything is covered by the starter housing.

Question: On the MS 180, the throttle button sticks in a horizontal position. What to do?

Answer: Most likely, the lever-traction mechanism is faulty, when the unit is turned over, one of the levers or rods “sinks”.

Question: Why does the cylinder heat up and when heated does the Stihl 180 chainsaw stall?

Answer: The problem is in the ignition module, perhaps there is no compression (necessary).

Question: We use a Stihl 180 chainsaw with a standard tire, recently found out that people put a Carving tire on this model. According to the catalog, you can put a 30 cm tire of this type, but is it possible to install 25 cm or not on this model?

Answer: Carving has a very small nose radius. It is better to use a 1/4 pitch chain with this bar. And this is where the problems begin. Such chains are very rare in retail, and plus to the 180th one can also find an asterisk for 1/4.

Maybe it makes sense to look for a 3/8 1.1 Rollomatic Mini tire at 30 cm. Its article is 3005 000 3905, if I'm not mistaken. She has a small nose with a 7-tooth sprocket. Somewhat larger than that of Carving, but not so picky about lubrication.

Question: Where should the arrow on the piston point towards the muffler or vice versa of the Stihl 180 C chain saw?

Answer: The arrow should point towards the muffler (the rule for all STIHL chainsaws).

Question: What is the clutch thread (left or right) on the MS 180 saw?

Answer: On all STIHL chainsaws, the clutch has a left-hand thread.

Question: The starter on the Stihl ms 180 chainsaw is jerky, what is the reason?

Answer: There can be several reasons - from a faulty starter (starter spring, etc.), to a faulty cylinder-piston group.

Chainsaw Stihl 180 does not start: causes and repair

Question: Why is there play in the chain sprocket on the Stihl 180 chainsaw?

Answer: Deterioration of the needle bearing of the clutch cup, but even on a new saw, the chain sprocket has minimal play!

Question: Stihl 180 chain saw. Second filling of gasoline, full tank. Gasoline oozes from below. Why?

Answer: The rubber band of the gas hose could pop out, it could overflow through the gas tank breather. The first must be corrected, the second is acceptable!

Question: At the Stihl 180 chainsaw, the chain does not move while the brake lever is in the middle position, and it starts to rotate only when you move it towards you.

What can be wrong?

Answer: The chainsaw chain brake has two positions: extreme, “away from you”, - this is the brake in the “on” working position, the chain does not move; the extreme “towards you”, move until it clicks, this is the brake in the cocked position, the chain rotates.

You most likely have the brake on, you need to move the handle to the extreme position “towards you”, i.e. pull the handle until it clicks, and if this does not help, then the brake is faulty and you need to contact the service center!

Question: How to properly adjust the carburetor of the Stihl MS 180 chainsaw?

Answer: On the Stihl 180 chain saw, only idle speed is regulated, since the carburetor is rolled and adjusted at the factory. Idling is regulated so that the chain does not rotate at minimum speed, or by a tachometer.

Question: Tell me what to do. The Stihl 180 chainsaw does not start. There is a spark, but it fills the candle and does not want to start. Where to start repairing or disassembling?

Answer: All repairs must begin by removing the muffler and seeing how the piston looks.

Question: The Stihl MS 180 chainsaw does not stall when the lever is moved up, I turn off the air damper, what should I do?

Answer: By moving the lever up, you interrupt the contact, in your case the contact is not interrupted, the contact spring “moved away” (bent), the wire of the contact spring may break, the control shaft (the lever that you lift up) is worn out.

Question: Tell me, how to replace the clutch springs on the Stihl 180 chainsaw?

Answer: clutch springs can be replaced even without removing the clutch. All you need is a small but strong hook made of strong wire and a standard “candle” key. We remove the cup, put the key on the hexagon of the coupling and unhook the stretched spring with a hook.

We immediately put a new one in its place - it’s easy there. We hook one hook of the spring with our fingers, and with a hook we pull the second into the hole. It will catch on, then we push it with a screwdriver so that it jumps into the hole properly.

We turn the crankshaft 1/3 of a turn, put the key on the hexagon again,
keep it from turning and also change the spring to a new one. Next - the third. We put the cup in place, we work. And you can also check the condition of the springs with your fingers.

The stretched spring allows the weights to move on the crosspiece and is removed very easily. When we replace the springs with new ones, the clutch should become like a monolith and it is not possible to pull the weights with your fingers, only if you rest with a screwdriver.

Question: Is it possible to install on a Stihl MS 180 chainsaw instead of a standard 30 cm bar, 1.3 tires from the 170th to 30 cm, but with a groove of 1.1? what is the danger of such a replacement?

Answer: In my opinion, only extra expense chains. Still, 1.1 has a shorter tooth (and on some models it is much shorter), there are fewer sharpenings.

Yesterday I bought a calm ms180. I started it, the tank was sleeping at idle. today I started sawing a little and it stalled and didn’t start, then you drink it for a long time, it starts up for a few seconds and stalls. I don’t know what to do, I don’t know what to do. money

Dmitry (Leyla) You violated the rules of operation!!! It is STRICTLY forbidden to run in at idle, in general, to run in something. Now change the candle, and finally saw it with a saw, you don’t need to run in anything there, the manufacturer has already done everything, full throttle, I emphasize FULL and sawing!) At first, the smoke will fall and black liquid will fly out of the muffler, in your case this is normal)) and no idlers, you don’t need a saw - muffle it.

When all the unburned oil burns out of the piston, everything stabilizes.

Maxim (Shemar) Thank you

Alexey (Jemmy), the manufacturer of the stihl saw does not run in, but as it should, I wrote earlier

Sergej (Porcius) Aleksey is right, thanks to him for the advice.

Evgeny (Flutura)  I don’t know how I brought it diluted gasoline and turned off 7 cubic meters of wood to work only at a gas station and the fire is working

Dmitry (Leyla)  Evgeniy did everything right.

Aleksei (Sharun)  guys tell me such a problem. bought a German 180 grandfather one. sawed well, then idling began to disappear. during work it was necessary to do perigasification. then poured gasoline into a canister poorly washed out of diesel oil. gasoline mixed as expected 1:20. filled in the brainchild of Germany STIHL MS180. the saw began to glitch. became high idle. but when you press the gas trigger, she began to choke and stall. maybe it's because of a poorly washed canister.

Dmitry (Leyla) Aleksei, poured oil in 2 s once again more than necessary, you need not 1:20, but 1:50 this is the first, the second gasoline for a high-speed gasoline tool itself must be perfect, from a proven branded gas station, and even more so not tainted with anything else)) ready mix do not store more than 3 - 4 weeks, do not use plastic for storage.

Aleksei (Sharun) Dmitry, thank you very much for the answer, now I will know. I just have a Chinese Husqvarna type saw, so even at 80 plates the speed does not drop and the idle is normal. after 6 years of work, it starts with 4 tsmyka. adjusted the carburetor. but with this German, oh, he was a little upset. Tomorrow I will torture him again. maybe the truth is that the whole sore is just leash in gasoline. thanks for the hint. good luck

Evgeny (Flutura) how to rivet the crankshaft and assemble..? write to pm

Dmitry (Leyla) Evgeny, no way..

Pavel (Lovett)   Tell your friends what to do, oil is flowing from under the muffler, but the tire is lubricated, you can see where in the photo ...
Oil drains quickly

Alexey (Jemmy)  Pavel, either change the crankcase, or take a thin drill and insert it into a small channel and cut the thread in this hole with an M6 tap, thoroughly clean it and screw in the screw until you hit the drill so that the chips do not get inside

Pavel (Lovett)   Alexey, ok) thanks, in short, I understood that I need to shut up this thing)

Alexey (Jemmy)  Pavel, that's right, the main thing is not to block the oil channel

Pavel (Lovett)  Alexey, thank you)

Alexander (Jewel) Is it possible to leave oil in the tank for long-term storage? MS180. And yet, is it possible to flush the oil system with kerosene (for example, when the oil is over and I leave the saw for storage) by pouring a small amount of kerosene into the tank - winding and a minute of progas? I wish you all successful preparation of firewood and heat in your house!!!

Dmitry (Leyla) Alexander, no special manipulations with the oil tank are required in most cases, drain the oil and that's it.

The Viktor (Latifa) 180 starts and runs well, but one problem is it doesn't turn off the way it's supposed to. what is the reason?

Chainsaw Stihl 180 not starting? Reasons and solution!

Chainsaw Stihl 180

To date, the manufacturer Stihl occupies a leading position among other companies that manufacture the production of equipment intended for agricultural and construction works. The products of this manufacturer are famous not only for their high level quality, but also optimal pricing policy and power of its models. This is one of the most famous companies in the world.

It is probably quite difficult to meet a person who would not have a chainsaw of this brand. But the fact that out of ten possible six people definitely have them. And this is not surprising, since Stihl chainsaws represent power along with graceful design. But unfortunately, such giants of technology sometimes fail and require some kind of repair. Today we will pay attention to one of the moles of this manufacturer, namely the Stihl 180 chainsaw. Read about the stihl ms 660 chainsaw here. So let's get started.

Briefly about the main

This model is the pride of the German manufacturer and is a direct tool designed for a small level of work. It can be used for no more than twenty hours a month. This wonderful device will easily help you manage your garden care, prepare firewood for winter period time (see

The main reasons why the Stihl chainsaw does not start and how to eliminate them

how to cut down a tree), produce cleared areas, and there will also be indispensable assistant in other areas, let's say, simple manipulations.

We can say that these mini-model chainsaws. as it has an insignificant weight, which is 3.9 kg. it does not have a large mass of the tank, both oil and fuel. The manufacturer equipped this device with a two-stroke engine with enough power for light work.

Moreover, it is quite quiet, since during operation the noise level does not exceed 98 dB. So that you better understand the very degree of loudness, just compare its noise with colloquial speech, which has an indicator of 76 dB.

The power of this model is equal to 2.6 W. It is worth noting that this is a fairly significant level of power, considering that it is not a professional chainsaw. The oil tank has a volume of only 0.145 liters, and the fuel tank has a volume of 0.25 liters. The tire has a size of 350 mm and a pitch of 0.325 inches.

Clockwork device

The basis of the plant of this kind of model, as well as all other chainsaws, is the carburetor. But since we are talking today about the Stihl 180 chainsaw, we will not deviate from the topic. So. The carburetor in this model has a single tuning screw. that is, it is a kind of idle adjustment screw. While the jet of a fully loaded load is in a stationary state.

In simple words, we can say that it simply cannot be adjusted (see here), while the full load setting simply cannot be changed. It is also important that the carburetor itself at the factory was set up in such a way that, regardless of the actual conditions under which the chainsaw is directly operated, the air-fuel mixture is supplied to the engine itself.

The saw does not start: causes and solutions

First of all, it is worth noting the fact that the 180 chainsaw of this manufacturer is one of his best “creations”, but it also has its drawbacks. In fact, which we will now talk about.

• A fairly common problem is that the Stihl 180 chainsaw does not start and fills the candle. The reason for this is that the oil that is poured in is to lubricate the chain. starts to leak. Since time is mercilessly and simply a violation of tightness is carried out exactly in the place where the hose from the oil pump and the oil tank is actually connected.

Naturally, this problem can be solved, but given the design of this chainsaw, it will not be so easy to do this, since you simply have to completely disassemble the device in order, as they say, to get to the right place. Seen more clearly:

• Many people are concerned about this question: why does the Stihl 180 chainsaw not start? If you believe the experts, then in such a situation, you first need to open, and then close the lid, which is located on the gas tank. Or take out and dry the candles. Or try to ventilate the combustion chamber. In most cases, this kind of manipulation is enough for the device to work. But there are times when the Stihl chainsaw does not start, but there is a spark ....
• In the above case, you need to directly check the supply of gasoline. air filter and direct performance of the candle. Since the basis of this kind of breakdown is the breather, namely its pollution. Because when it is completely clogged, a kind of vacuum arises in the gas tank itself, which simply interferes with the fuel supply process. Solving this issue is not difficult, since all you need to do is clean it using a needle.
• There are also situations when the device, in principle, started up, but immediately died out.
  The main causes of this kind of malfunction are the carburetor and filter, which could simply become clogged.

  In order to exclude the saloon from damaged objects, it is necessary first of all to disconnect the fuel hose from the carburetor itself and actually check whether fuel is leaking from it.

• You must remember that during the correct operation of the chainsaw, gasoline must flow out in a dense and stable stream. It is also not uncommon for the Stihl 180 chainsaw to not start hot and actually stall after turning on, or hold power for a fairly short time.

  In this case, the problem of breakdown lies precisely in the muffler, which can simply be clogged with any deposits that arise through the operation of the device and which settle during the exhaust process.

• Also enough common cause tool failure is insufficient lubrication of the device circuit itself. The reason for this may be the channels that are simply clogged, or the reason is in the oil line that is leaking.

Chainsaw chain lubrication

• The connecting pipes or the connections themselves in the area of ​​the oil pump fittings can also leak.
• It happens that the Stihl 180 chainsaw does not start well due to a cylinder that can be broken. But to determine its condition, a visual inspection is sufficient. But if even there you find the formation of bumps and chips, then you can be sure that you have found the cause of the breakdown.
• If by checking you find that the malfunction is in the candle. then you simply need to turn it out, and then dry it directly. But it is worth noting that in no case should it be pierced, as you will simply spoil the part, and it will be unusable.

  You also need to drain excess fuel from it through a special hole.

  In addition, you must remember that direct drying should be carried out for at least thirty minutes, and only after such manipulations can you install it back and actually try to start the tool directly.

  Moreover, it may be that your candle has simply passed its expiration date, in which case it is necessary to replace it. Therefore, the best advice is that it is best to always have a new candle or a set in reserve. Then you can replace it at any time and actually understand whether it was the direct cause of the device failure. Moreover, a weak contact can also be the cause of the breakdown, which actually connects the high-voltage wire and the end of the candle. Also, the cause may be a breakdown of the ignition unit. It is worth noting the fact that in order to eliminate this kind of problem, it is necessary to replace the unit itself, since it cannot be repaired.

• Equally important is the excitement of the owners of this model regarding the systematic idling after the actual first gasoline tanks are empty. But if you believe the experts in this field, they argue that this kind of situation does not pose any problem. But still, if this kind of process is repeated often enough, then you need to simply reduce the engine speed by using a carburetor screw.
• In addition, you can personally clean the muffler itself. since the cause of the malfunction may be in it. This manipulation is not difficult.

  A fairly common occurrence of poor-quality tool work is a carburetor.
  But it is worth noting that it would be best if specialists repair it, because if you have the necessary knowledge and skills, then you can simply break it and have to buy a new one.

It is also important that even if you have discovered the very cause of a tool malfunction, this does not mean at all that you can fix it yourself. Since there are such breakdowns that only a specialist can fix. If you have carried out a direct manipulation regarding checking and replacing the quality of the oil (see Stihl chainsaw oil), but, nevertheless, the chainsaw still refuses to start in this case, you must continue to search.

But if you fully performed all the manipulations prescribed above and did not miss a single nuance, but still the tool has not yet been corrected, then in this case the problem lies in the group called the cylinder. But if you still couldn’t “bring back to life” your iron friend, then simply take the chainsaw to a service center where your device will be repaired.

Summing up…

In fact, as you can see, there are a lot of reasons for the breakdown of the Stihl 180 chainsaw, and at the same time, there are also quite a few solutions to this problem. If you are faced with this situation, then simply follow all the recommendations written above and then, undoubtedly, you will be able to repair your device, and it will delight you with its work for many more years.

What could be the reason why the Stihl MS 180 saw does not start?

The MC 180 chainsaw does not start. Washed the candle with acetone, sanded with fine sandpaper. Several months was not used, benz and oil remained in the tank, but had previously started from the 50th time. Tell me where to look and what to do. Also, please send a repair manual if available.

Because If you had gasoline left in the tank, then by 80 percent you need to clean the carburetor - this is the first. Secondly, the saw starts if fuel is supplied to the cylinder, there is a spark and compression. The lack of fuel supply can be seen by a dry candle (we disassemble and clean the carburetor, change the fuel filter, clean the impulse channel). If there is no spark, then change the candle, if the replacement did not help, then you need to change the magneto. If there is no compression, then it is necessary to change the piston, cylinder and seals. I advise you to start by removing the muffler and look at the condition of the piston (there are scuffs on the piston or not).

I have had exactly the same saw for three years now, it has been working properly and starts normally. If it has started like this before, change the spark plug, you came across with a low-quality spark plug.

If the Stihl 180 chainsaw does not start: instructions

Do not save on candles, take a branded one from the catalog. Good luck.

This, at your request, is an instruction for starting the saw, but about what you can sin if the saw didn’t start well, and now it doesn’t start at all - most likely the ringlets have already come to an end and there is no compression, which is why, if it starts by a miracle, having worked, it will heat up the piston, reducing the clearance, and then it will work normally. Needs to be repaired! It is not necessary to change the rings, the piston.

The second option - if the chainsaw, according to the norm, should not yet be so worked out that there is no compression, then the point is in the carburetor settings, you need to clean and adjust the carburetor, then what are you doing there sandpaper a rubbed candle will not bring much benefit!

• I almost forgot the chainsaw can start badly if a lot of oil is poured into gasoline, or low-quality oil oil mixed with gasoline is special, not ordinary motor oil!

Therefore, advice - if you yourself are not afraid, you need to climb on the Internet and find information on repairing a piston and setting up a carburetor, if it’s scary it means taking it to a service, I’ll say that it’s okay to disassemble and repair a chainsaw, and spare parts in special stores are in bulk for all models, and full of online stores!

If the saw was with gasoline for a long time, but did not start, then pour out the old gasoline from the tank and pour in a new one, the saw will not start very quickly the first time, and then it will start working normally. If the candle is normal, then do not forget to check the spark, otherwise it is clean, but it is useless. Next, clean the air filter or replace it with a new one and Special attention it is necessary to give such an inconspicuous crack, which must always be clean, otherwise the saw will start with great difficulty, I marked this place with an arrow
Well, it’s not at all superfluous to check the gasoline filter that is in the tank, pull it out and clean it if it is dirty. If these measures do not help, then you will have to carry Calm to a specialist, which means something serious has happened.

If it has previously been started from the fiftieth time, then it is worth giving it to the service, since maintenance of all systems is necessary. But the company and model are not bad. That is, cleaning the carburetor itself, and checking the condition of the pistons and rings. If, for example, oil is thrown into the combustion chamber, then, as you understand, there is nothing good in this. The fact is that the gasoline engine of a chainsaw is not much different from a car engine, and if it does not start, then its bulkhead is required, in the worst case.

To date, the manufacturer Stihl occupies a leading position among other companies that manufacture the production of equipment intended for agricultural and construction work. The products of this manufacturer are famous not only for their high level of quality, but also for the optimal pricing policy and the power of its models.

It is probably quite difficult to meet a person who would not have a chainsaw of this brand. This is one of the most famous companies in the world. But the fact that out of ten possible six people definitely have them. And this is not surprising, since Stihl chainsaws represent power along with graceful design. But unfortunately, such giants of technology sometimes fail and require some kind of repair. Today we will pay attention to one of the moles of this manufacturer, namely the Stihl ms 180 chainsaw. Read about the stihl ms 660 chainsaw. So let's get started.

Briefly about the main

This model is the pride of the German manufacturer and is a direct tool designed for a small level of work. It can be used for no more than twenty hours a month. This wonderful device will easily help you manage your garden care, prepare firewood for the winter period (see how to cut a tree), make cleared areas, and will also be an indispensable assistant in other areas, let’s say, simple manipulations.

The Stihl MS 180 chainsaw is considered one of the most reliable tools used for working on garden plots. But for any equipment, there are situations when, for some reason, it does not start. Let's look at the main malfunctions due to which the calm 180 does not start or starts poorly and how to fix these malfunctions.

The main malfunction due to which the stihl ms 180 chainsaw does not start 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 found during the inspection that the candle is wet, it is necessary to start searching for the reason for the absence of a spark on the spark plug.

Faulty spark plug

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

It's pretty easy to do this. The candle is inserted into the cap of the high-voltage wire and pressed against the engine cylinder, after which the starter moves several times, if there is no spark between the electrodes of the candle, then it is faulty or the ignition module is faulty.

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

In order to know for sure that the problem is in the spark plug, you need to check a known-good the same way. If a spark appeared as a result of the check, then the problem was found and to eliminate the malfunction, we replace the candle with a new one.

Problems with the ignition coil

The ignition coil, also called the module, has a non-separable design, so it is very difficult to determine its performance without a special tool. If the spark on the working candle did not appear, suspicions arise that the coil is to blame. But do not immediately remove the old coil and run to the store, the problems may be of a slightly different nature.

No gap between flywheel and ignition module

In some cases, the absence of a spark on the spark plug is due to an incorrect gap between the contacts of the ignition module or the flywheel. It may be larger, or it may not be at all, and then scratches will be observed on the surface of the flywheel as a result of contact with the coil contacts.

You can check and set the gap without having a special tool. To do this, you will need to remove the starter, loosen the two coil mounting screws and lay a plate cut from plastic bottle, tighten the module fixing screws.

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

Defective crankshaft bearings

If the crankshaft bearings are defective, a slight play is observed on it. You can check for backlash by shaking the flywheel of the Stihl 180 chainsaw from side to side. If there is play, then under the action of its magnets, the flywheel is attracted to the contacts of the ignition coil, because the play on the bearings allows it to do this and as a result the spark disappears.

Replacing crankshaft bearings

It is better to replace the crankshaft bearings in a specialized service, because when replacing, you will need to completely disassemble the Stihl 180 chainsaw and remove all its main components.

Without a certain experience, or at least the skills to repair similar chainsaws, it will not work to replace the crankshaft bearings with high quality.

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

Stihl 180 fuel system problems

In some cases, as a rule, if there is a spark on the spark plug, when examining it, you can notice that it has a wet coating, this indicates an excessive supply of fuel to the combustion chamber and, as a result, the impossibility of igniting the fuel mixture.

Pours a candle

In the people, the phenomenon in which a spark cannot ignite a large amount of fuel is commonly called pouring a candle. The cause of the malfunction lies in the carburetor, or in the wrong start of a cold engine. If a malfunction is detected, first you need to “purge” the engine.

Engine "purge" algorithm

Important: in any case, do not "purge" the engine with the ignition on and near an open flame.

• Turn out the candle;
• Turn the Stihl 180 chainsaw upside down and drain excess fuel;
• In an inverted state, pull the chainsaw starter several times (thus, under the influence of compression, excess fuel will be removed from the cylinder);
• Install the candle and the cap of the high-voltage wire in place;
• Set the engine control lever to the hot start position;
• Pull the starter several times and start the engine.

If everything is in order with the Stihl chainsaw and the cold start algorithm was simply violated, then after “purging” it should start. Otherwise, the fault must be sought in the carburetor.

No fuel coming in

This type of malfunction, like the others, has its own feature. It consists in the fact that a working spark plug, on which there is a spark, will be absolutely dry. You can check suspicions of a lack of fuel supply using the following algorithm.

Algorithm for checking for lack of fuel supply

• Unscrew the candle;
• Using a syringe, pour 1-2 cubes of the fuel mixture into the candle hole;
• Install the candle and put on the cap of the high-voltage wire;
• Set the engine control lever to the hot start position;
• Pull the starter several times.

If, after several movements with the starter, the Stihl 180 chainsaw started up and immediately died out, then the suspicions of the lack of fuel supply were confirmed and you can proceed to further diagnostics of the fuel line.

Fuel Line Diagnostics

As a rule, diagnostics of the fuel supply system begin with checking the condition of the fuel filter. To do this, unscrew the tank cap and, using an aluminum wire bent at the end, remove the fuel hose from the tank with a filter at the end.

Having taken out and dismantled the filter, you can try to blow into it, if the air does not go, then the problem is found. If everything is in order, then you need to check the system for blockage.

To check the fuel supply hose, it is necessary to disconnect it at the place where it connects to the carburetor, and then blow into it. A clogged hose can be mechanically cleaned, if this is not possible, replaced with a new one.

In the event that the supply hose and fuel filter are normal, and no fuel supply is observed, the cause may be hidden in a malfunction in the supply of an air pulse to the fuel pump.

Checking the pulse from the crankcase

The fuel pump on the Stihl MS 180 chainsaw is installed directly in the carburetor and operates under the influence of impulses from the engine crankcase of the Stihl 180 chainsaw. The impulse is transmitted through the impulse channel in the rubber pipe connecting the cylinder to the carburetor.

Clogging of the channel is fraught with problems with the supply of fuel or its complete absence. To check the pipe, it is necessary to remove the air filter housing and the carburetor, and then check the channel for blockage with a thin metal wire.

All rubber parts Stihl 180 chainsaws should be periodically inspected for cracks. If defects are found, the defective elements must be replaced with new ones.

Another reason associated with the absence of a pulse in the pipe channel is the depressurization of the engine crankcase, which results in air leakage from it and a decrease or complete cessation of its supply to the fuel pump. The result of depressurization is a partial or complete loss of fuel pump performance. To check the tightness of the crankshaft oil seals, and indeed the crankcase of the Stihl 180 chainsaw, a special vacuum gauge is used, and since it is a special-purpose tool, it is mainly available only in service centers. The question arises, what to do?

You can check the impulse supply with a syringe on the engine with the carburetor removed. You will need to draw a little oil into the syringe to lubricate the engine and squeeze it into the impulse channel of the pipe, then pull the starter. If the pulse does not pass, the oil will remain in the channel and you should look for the cause deeper, disassemble the engine and check the seals. If oil is squeezed out of the channel, then the problem may be hiding in the fuel pump itself.

Fuel pump

The main element of the fuel pump is a special membrane that moves in the pump housing. When it breaks, the fuel supply to the carburetor and the engine of the Stihl 180 chainsaw stops. You can check the integrity of the membrane visually with the fuel pump cover removed; if there are defects (tears, cracks), it can be replaced using repair kit for the carburetor.

If your Stihl 180 chainsaw does not start, and after reading the material it is difficult to understand what and how to do in order to find and fix the problem, you should not immediately drop everything and write in a search engine: the Stihl 180 chainsaw does not start video reasons. Just below you will find a video instruction, where the master service center talks in detail about the malfunctions that prevent the Stihl 180 chainsaw from starting, and also explains why the saw does not start hot.
