To work on your own personal plot or private home, farming or construction requires such universal tool like a chainsaw. Wood has always been, is and will be relevant building material, for the processing of which such a unique device is necessary. A chainsaw is also indispensable when collecting firewood, trimming green spaces, improvement and management of your farm.

DIY chainsaw repair Shtil 180

Chainsaw Shtil MS 180 designed for inexperienced users to make using this tool as easy as possible. This chainsaw is lightweight and easy to use, and also has a low cost, due to which it is in great demand among the population. With intensive use of the tool, parts wear out, which leads to tool malfunctions. Some of the most common and typical faults You can fix it yourself at home. As a rule, users have the following questions: Why does the chainsaw have trouble picking up speed? Why isn't the chain lubricated?

Types of faults, diagnostics, tools for repairs

For Chainsaw troubleshooting you need to have the appropriate tools. This list should include the following tools:

set of wrenches;
set of socket wrenches;
Screwdriver Set;
needle.

Before you begin troubleshooting a chainsaw, you need to accurately determine the causes of the malfunction and localize the location of the breakdown. Since a chainsaw has an engine internal combustion It is logical to assume that the main malfunctions will be associated with this device. The most common malfunctions encountered during saw operation are:

ignition system malfunctions;
fuel system malfunctions;
malfunctions of the cylinder and piston group;
muffler malfunction;

Malfunctions not related to engine operation are also common. These include the following malfunctions:

brake and clutch malfunctions;
malfunction of the chain lubrication system;
broken starter cord;
drive sprocket wear.

Troubleshooting Engine operation must begin by checking the gasoline level in the fuel tank. If the fuel level is normal, we start checking basic chainsaw systems.

Ignition system

Problems in the ignition system of a chainsaw can be judged by the following signs:

The engine will not start;
the engine starts, but stalls almost immediately;
the engine is unstable;
does not develop full power or stalls.

Checking the ignition system You should start by inspecting the spark plug. The verification scheme is simple. The spark plug must be clean, free of carbon deposits and not filled with fuel mixture. The gap between the electrodes should be 0.5–0.65 mm. Carbon deposits from the spark plug can be removed with a sharp awl; the electrodes should be cleaned with fine sandpaper.

Startup problems can also occur due to damage to the sealing gasket of the spark plug or its wear. Next, check the spark plug for a spark. To do this, you need to connect a high-voltage wire to it and, holding the spark plug with pliers with insulated handles, attach it to the cylinder with its thread. By pulling the starter cord, check for the presence of a spark. If there is no spark, then the spark plug should be replaced. If there is no spark and new candle, then the problem should be sought in the high-voltage wire.

Fuel system

Problems with the fuel system of the Shtil chainsaw can sometimes be determined by the condition spark plug. So, if the spark plug remains dry during inspection, this indicates that the fuel mixture does not enter the cylinder. The most common cause is a clogged fuel filter. To repair, you need to remove the fuel hose from the carburetor and see how the fuel flows. If the stream is weak, then you need to remove the fuel filter through the fuel filling hole and clean it. At heavy pollution It is recommended to replace the filter with a new one.

Another common problem is breather blockage. The breather is a small hole in the gas tank cap; you need to use a needle to clean it. An insufficient amount of fuel mixture may be due to a clogged air filter; in this case, air does not enter the the required volume, fuel mixture turns out to be too rich, which leads to unstable engine operation. To eliminate the malfunction, the filter must be removed, thoroughly washed and dried, and reinstalled.

If these methods do not help resolve the problem, then the problem may be due to improper carburetor adjustment. Carburetor adjustments should be made with clean air and fuel filters. On most carburetors, adjustment is made using three special screws: maximum speed, minimum speed and idle speed adjustment. Maximum speed screw designated by the symbol H, it controls the main jet. Screw L is designed to adjust the minimum speed and controls the idle jet. Screw S finely adjusts the idle speed.

Sometimes found in carburetors two adjustment screws, which is done to simplify setup. Accurate carburetor setting data should be taken from the instruction manual, but it is better to entrust this operation to specialists, since this is a very complex and responsible job.

Cylinder and piston group

If the engine does not develop full power or does not start, the problem may be insufficient pressure in the cylinder. This can happen due to wear of the cylinder, crankshaft bearings, as well as due to the piston rings sinking due to piston wear; disassembly and reassembly of the muffler is required. If you remove the muffler in a calm weather, you can visually assess the condition of the cylinder and piston group by looking into the hole from the muffler. The overview will be small, but you can get an idea of the condition of the cylinder and piston.

For more accurate diagnostics, you can use a compression gauge, which is installed in the spark plug hole. Having turned the starter over, we determine cylinder pressure. The pressure with a working CPG should be about 8–9 atmospheres. A decrease in pressure leads to a decrease in the power of the calm engine. To determine the full picture of the condition of the CPG, you need to completely disassemble the engine, disconnecting the crankcase from the cylinder and inspecting the piston. To perform this work, you need to study the design of the Stihl 180 chainsaw; it is also recommended to watch videos of this work on the Internet. Reassemble the engine in reverse order.

Chainsaw muffler

If the engine runs fine at idle, but stalls when the speed increases, there is a possibility that the muffler is the cause. The muffler may become clogged with fuel combustion products and block exhaust outlet and, as a result, the engine does not develop maximum speed. The reason may be excess oil in fuel, as well as unsuitable or low-quality oil. To eliminate the malfunction, the muffler must be removed, cleaned of carbon deposits and washed with detergents.

Chain brake, clutch, lubrication system

The reason for the failure of the calm 180 may also be faulty chain brake. Most often, the space under the gearbox cover becomes clogged or the brake band wears out. If clogged, remove the cover and clean thoroughly. inner space. Repair in case of wear of the brake band consists of replacing it.

Oil leaks in the chain drive unit are often visually visible, which leads to incorrect operation of the servo. To fix the problem, you need to check the quality of the connection between the oil pump fitting and the tube, and inspect them for cracks. If cracks are found, parts must be replaced or sealed with sealant. If there is not enough oil supplied to the chain, then you need to clean the channels for supplying lubricant, which happens quite often.

If the chain of a chainsaw spins almost constantly, and the engine sometimes runs unstable, then the fault should be looked for in the clutch. This could be a broken spring, or a piece of the clutch cam could break off. The problem can be resolved by replacing this unit.

During operation of a chainsaw, parts wear unevenly. To maintain the functionality of the device, it is necessary to promptly replace worn parts, such as a chain, drive sprocket, tire and others. In this case, the Shtil 180 chainsaw will work flawlessly for a long time.

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

After this it doesn't want to start. The next day, after unsuccessful attempts to start it, I removed it and washed it. air filter. It didn’t help, I had to remove the spark plug - 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). I changed the fuel filter (although the old one was not visually dirty). I cleaned the carburetor and installed a new spark plug just in case. The saw won't start! I unscrewed the spark plug again - it was dry. What to do?

Answer: Remove the muffler. Look at the piston, if there are longitudinal stripes on it, then it needs to be replaced.

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

Answer: There is no difference between a “drive sprocket” and a “spin wheel”, this is different names the same detail.

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

Answer: Standard length MS 180 tires - 35 cm, it is possible to cut a log - 70 cm in diameter, if logs of this diameter predominate, then you need a chainsaw of greater power.

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

Question: Please tell me, is it possible to use a 45 cm guide bar on a Stihl 180 chain saw?

Answer: You can install a tire on the MS 180 chain saw maximum length 40 cm.

Question: Where is the breather located in the Shtil ms 180 chainsaw?

Answer: Valve ventilation system(“breather”) is located “on top” of the gas tank and oil tank, it cannot be seen visually, because everything is covered by the starter housing.

Question: On the MS 180, the gas button gets stuck 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 “falls”.

Question: Why does the cylinder heat up and when it heats up, does the Stihl 180 chain saw 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 bar; we recently found out that people are installing a Carving bar on this model. According to the catalog, you can install a 30 cm tire of this type, but is it possible to install a 25 cm tire or is it not possible on this model?

Answer: Carving has a very small nose radius. It is better to use a chain with a 1/4 pitch with this tire. And this is where the problems begin. Chains like this are very rarely available in retail, and in addition to the 180th, you can also find a 1/4 sprocket.

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

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

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

Question: Tell me, what is the clutch thread (left or right) on the MS 180 chain saw?

Answer: All STIHL chainsaws have a left-hand thread on the clutch.

Question: The starter on the Shtil ms 180 chainsaw pulls out jerkily, what is the reason?

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

Chainsaw Shtil 180 will not start: causes and repairs

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

Answer: The clutch cup needle bearing is worn out, but even on a new saw the chain sprocket has minimal play!

Question: Shtil 180 chain saw. Second fill of gasoline, full tank. Gasoline is seeping from below. Why?

Answer: The gas hose rubber could have popped out and could overflow through the gas tank breather. The first needs to be corrected, the second is acceptable!

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

What can be wrong?

Answer: The chain brake on a chainsaw has two positions: the extreme position, “pull away”, - this is the brake in the working position “on”, the chain does not move; move the extreme “towards you” 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 “towards you” position, i.e. pull the handle until it clicks and if this does not help, then the brake is faulty and you need to contact service center!

Question: How to properly adjust the carburetor of the Shtil MC 180 chainsaw?

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

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

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

Question: The Stihl MS 180 chainsaw does not stall when the lever is moved up, I turn it off with 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 has “moved away” (bent), the contact spring wire may be broken, the control shaft (the lever that you lift up) may be worn out.

Question: Tell me how to replace the clutch springs on a Shtil 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 spark plug wrench. We remove the cup, put the key on the hexagon of the coupling and use the hook to unhook the stretched spring.

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

Turn the crankshaft 1/3 of a turn, put the hex key back on,
keep it from turning and also replace the spring with a new one. Next - the third. We put the cup in place and work. You can also check the condition of the springs with your fingers.

The stretched spring allows the weights to move on the cross and can be 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 off with your fingers, only if you push against it with a screwdriver.

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

Answer: In my opinion, only unnecessary consumption of chains. Still, 1.1 has a shorter tooth (and on some models, much shorter), resulting in fewer sharpenings.

Yesterday I bought a calm ms180. I started it and slept the tank at idle. Today I started sawing a little and it stalled and won’t start, then you drank it for a long time, it starts up, works for a few seconds and stalls. What should I do? I don’t know what to do. Is it possible to return it and will they return it? money

Dmitry (Leyla) You violated the operating rules!!! It is STRICTLY forbidden to break in at idle speed, or to break in anything at all. Now change the spark plug, and finally cut with a saw, there is no need to break in anything, the manufacturer has already done everything, full throttle, I emphasize FULL and saw!) at first there will be smoke and black slurry will fly from the muffler, in your case this is normal)) and no idle, no need for a saw - turn it off.

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

Maxim (Shemar) Thank you

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

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

Evgeny (Flutura) I don’t know, as soon as I brought it, I diluted the gasoline and put 7 cubic meters of wood into work, only to fill it up and the fire works

Dmitry (Leyla) Evgeniy, he did everything right.

Aleksei (Sharun) Guys, tell me this is the problem. I bought a German 180 from my grandfather. It was sawing well, then the idle speed began to disappear. When working, it was necessary to perform peregazovka. then he poured gasoline into a canister that had been poorly washed out of diesel oil. I mixed gasoline as required 1:20. poured STIHL MS180 into the brainchild of Germany. the saw began to malfunction. became high idle. but when I pressed the gas trigger, she began to choke and stall. Maybe this is due to a poorly washed canister.

Dmitry (Leyla) Aleksei, I poured more than 2 times more oil than necessary, you need not 1:20, but 1:50, this is the first, second, gasoline for high-speed gasoline tools itself must be impeccable, from a proven branded gas station, and even more so not bothered by anything)) ready mixture Do not store for more than 3 - 4 weeks, do not use plastic for storage.

Aleksei (Sharun) Dmitry, thank you very much for your answer, now I’ll know. I just have Chinese saw like Husqvarna, even at 80 slabs the rpms don’t drop and the idle is normal. After 6 years of operation, it starts with 4 keys. I adjusted the carburetor myself. but with this German I was a little upset. Tomorrow I will torture him again. Maybe the whole problem is just in the gasoline. thanks for the tip. Good luck

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

Dmitry (Leyla) Evgeniy, no way..

Pavel (Lovett) Friends, tell me what to do, oil is leaking from under the muffler, but the tire is lubricated, you can see in the photo where it comes from...
Oil leaves the reservoir quickly

Alexey (Jemmy) Pavel, either change the crankcase, or take a thin drill and insert it into a small channel and cut a thread in this hole with an M6 tap, clean it thoroughly and screw in the screw until it hits the drill, the main thing is that no chips get inside

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

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

Pavel (Lovett) Alexey, thank you)

Alexander (Jewel) Can I leave it on? long-term storage oil in tank? MS180. And also, is it possible to flush the oil system with kerosene (let’s say when the oil runs out and I leave the saw for storage) by pouring a small amount of kerosene into the tank - start it up and let it run for a minute? Good luck to everyone in collecting firewood and heating your home!!!

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

Viktor (Latifa) 180 starts and works well, but one problem is that it does not turn off as it should. what is the reason?

Who can tell me how to adjust the carburetor on a Stihl chainsaw? | Topic author: Olesya

WHEN COLD IT WORKS NORMAL, BUT AFTER LOAD, it feels like there is not enough fuel, it stalls at idle. This happened in snowy weather, maybe the air filter? And could there be a winter-summer mode at ms 180?

Inna what seals are what carburetor on any file there are 3 regulators, one for idle speed - you don’t need to touch it. and two together, that’s what needs to be regulated. Below them there are the letters H and L. H is a coarse setting and L is a fine setting. turn the fine adjustment half a turn clockwise or counterclockwise while working. along the way you will understand everything: if the speed drops, then turn in the other direction. and clean the air filter on time.

Artyom shouldn’t go there.

The Shtil 180 chainsaw does not start: the main reasons

change the mixture to the freshest one and everything will work!
I ADDITION, if there are symptoms/it is difficult to start hot/ - change the seals on the shaft.
And add idle, it’s not hard. I don’t know what model we’re talking about, most likely a hobby, there are only two bolts, one pushes the lever. So screw it on

Shtil 180 chainsaw won't start? Reasons and solution!

Chainsaw Shtil 180

Today, the manufacturer Shtil occupies a leading position among other companies that produce equipment intended for agricultural and construction work. The products of this manufacturer are famous not only for their high level quality, but also the optimal pricing policy and power of its models. This is one of the world's most famous companies.

It is probably quite difficult to meet a person who does not have a chainsaw of this brand. But the fact is 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 break down and require a certain kind of repair. Today we will pay attention to one of the brands 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 thing

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

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

how to cut down a tree), make cleared areas, and will also an indispensable assistant in other areas, let’s say, simple manipulations.

We can say that these are mini model chainsaws. since it has a small weight, which is 3.9 kg. It does not have a large tank mass, both oil and fuel. Manufacturer equipped this device two-stroke engine with ample power for light work.

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

The power of this model is 2.6 W. It's 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 - 0.25 liters. The tire has a size of 350 mm and a pitch of 0.325 inches.

Winding device

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

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

The saw does not start: reasons 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. Actually, which we will talk about now.

Enough common problem is that the Shtil 180 chainsaw does not start and floods the spark plug. The reason for this is that the oil that is poured in to lubricate the chain. starts to leak. Since time is merciless and the seal is simply broken 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, this will not be so easy, since you will 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 Shtil 180 chainsaw not start? If you believe the experts, then in such a situation you need to first open and then close the cap located on the gas tank. Or take out and dry the candle. Or try to ventilate the combustion chamber. In most cases, this kind of manipulation is quite enough for the device to work. But there are times when the Shtil chainsaw does not start, but there is a spark...
In the above case, you need to directly check the gasoline supply. the air filter and the immediate performance of the spark plugs. Since the basis for this type of breakdown is the breather, namely its contamination. Because when it is completely clogged, a kind of vacuum appears 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 basically started up, but immediately stalled.
The main reasons for this type of malfunction are the carburetor and filter, which could simply be 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 in the process correct operation chainsaws, gasoline should flow out in a dense and stable stream. It is also not uncommon for the Shtil 180 chainsaw to not start when hot and actually stall after switching on, or to 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 The malfunction of the tool is insufficient lubrication of the device circuit itself. The reason for this may be channels that are simply clogged, or the reason is an oil line that is leaking.

Chainsaw chain lubrication

May also occur connecting tubes or the connections themselves in the area of the oil pump fittings.
It happens that the Shtil 180 chainsaw does not start well due to the cylinder, which may be broken. But to determine its condition, a visual inspection is sufficient. But if there you find the formation of irregularities and chips, then you can be sure that you have found the cause of the breakdown.
If, through inspection, you find that the fault is in the spark plug. then you simply need to turn it out and then dry it directly. But it is worth noting that under no circumstances should you pierce it, as you will simply ruin 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 this kind of manipulation can you install it back and actually try to start the tool directly.

Moreover, it may also be that your candle has simply passed its expiration date, in which case it is necessary to replace it. Therefore, excellent advice is that it is best to always have a new candle in stock, or preferably a set. Then you can replace it at any time and actually understand whether it was the direct cause of the device failure. Moreover, the cause of the breakdown may also be a weak contact, which actually connects the high-voltage wire and the end of the spark plug. A faulty ignition unit may also be the cause. 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.
Also important is the concern of the owners of this model regarding the systematic idling after the first gasoline tanks have been emptied. But if you believe the experts in this field, they claim that this kind of situation does not pose any problem. But still, if this kind of process is repeated quite often, then you need to simply reduce the engine speed by using the carburetor screw.
In addition, you can clean the muffler itself. since this may be the cause of the malfunction. This manipulation is not difficult.
A fairly common occurrence of poor-quality tool performance is the carburetor.
But it is worth noting that it would be best if specialists deal with its repair, since if you have necessary knowledge and skills, then you can simply break it and have to buy a new one.

It is important that even if you have discovered the very cause of the tool malfunction, this does not mean at all that you will be able to eliminate it yourself. Since there are such types of breakdowns that can only be corrected by a specialist. If you have carried out direct manipulation regarding checking and replacing the quality of the oil (see oil for the Shtil chainsaw), but, nevertheless, the chainsaw still refuses to start, then you need to continue your search.

But if you have fully carried out all the manipulations prescribed above and have not missed a single nuance, but the tool has still not been corrected, then in this case the problem lies in the group, which is called the cylinder group. 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.

To sum it up...

In fact, as you can see, there are quite a lot of reasons for the breakdown of the Shtil 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 years to come.

What could be the reason that the Shtil MC 180 saw does not start?

Chainsaw til MC 180 does not start. I washed the spark plug with acetone and sanded it with fine sandpaper. Several months It was not used, the gasoline and oil remained in the tank, but it had previously started from the 50th time. Tell me where to look and what to do. And please also send the repair instructions if available.

Because If you have gasoline left in the tank, then 80 percent of the time you need to clean the carburetor - this is the first thing. 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 spark plug (we disassemble and clean the carburetor, change the fuel filter, clean the pulse channel). If there is no spark, then change the spark plug; if the replacement does not help, then you need to change the magneto. If there is no compression, then the piston, cylinder and seals must be replaced. I advise you to first remove the muffler and look at the condition of the piston (whether there are scuffs on the piston or not).

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

If the Shtil 180 chainsaw does not start: instructions

Don’t skimp on candles, buy branded ones from the catalogue. Good luck.

This is, at your request, instructions for starting the saw, but as for what you can do if the saw didn’t start well, and now won’t start at all - most likely the rings have already come to an end and there is no compression, which is why, if it starts miraculously, After working, it heats up the piston, reducing the gap and then it works normally. Needs renovation! It is not necessary to change the rings or piston.

The second option - if the chainsaw, according to the norm, should not be so used that there is no compression, then the problem is in the carburetor settings, you need to clean and adjust the carburetor, then what are you sandpaper Rubbing a candle won't do much good!

I almost forgot, a chainsaw can be difficult to start if a lot of oil is poured into the gasoline, or oil Low quality The oil mixed with gasoline is special, not ordinary motor oil!

Therefore, advice - if you yourself are not afraid, you need to surf the Internet and find information on repairing the piston and setting up the carburetor, if you are afraid, then take it to the service center, I will say that there is nothing wrong with disassembling and repairing the chainsaw, and there are spare parts in bulk in special stores for all models, and There are plenty of online stores!

If the saw was left with gasoline for a long time, but did not start, then pour the old gasoline out of the tank and pour in new one; the first time the saw will not start very quickly, but then it will start working normally. If the spark plug is normal, then don’t forget to check the spark, otherwise it’s clean, but it’s of no use. Next, clean the air filter or replace it with a new one and Special attention you need to pay attention to such a crack, which should always be clean, otherwise the saw will start with great difficulty, I marked this place with an arrow
Well, it wouldn’t hurt to check the gasoline filter, which is located in the tank, take it out and clean it if it’s dirty. If these measures do not help, then you will have to take Shtil to a specialist, which means something serious has happened.

If it has previously started up after the fiftieth time, then it is worth giving it for service, since servicing 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 about it. 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 it needs to be rebuilt, in the worst case.

I have the exact same saw for three years now, it has been working properly and starts normally. If it started like this before, change the spark plug, you were caught with a low-quality spark plug. Don’t skimp on candles, buy branded ones from the catalogue. Good luck.

At your request, these are instructions for starting the saw, but as for what you can do if the saw didn’t start well, and now won’t start at all - most likely the rings have already come to an end and there is no compression, which is why, if it starts miraculously, After working, it heats up the piston, reducing the gap and then it works normally. Needs renovation! It is not necessary to change the rings or piston.

The second option - if the chainsaw, according to the norm, should not be so used that there is no compression, then the problem is in the carburetor settings, you need to clean and adjust the carburetor, then rubbing the spark plug with sandpaper will not bring much benefit!

I almost forgot, a chainsaw can be difficult to start if a lot of oil is poured into the gasoline, or the oil is of low quality The oil mixed with gasoline is special, not ordinary motor oil!

If the saw was left with gasoline for a long time, but did not start, then pour the old gasoline out of the tank and pour in new one; the first time the saw will not start very quickly, but then it will start working normally. If the spark plug is normal, then don’t forget to check the spark, otherwise it’s clean, but it’s of no use. Next, clean the air filter or replace it with a new one, and special attention should be paid to the inconspicuous gap, which should always be clean, otherwise the saw will start with great difficulty, I marked this place with an arrow

Well, it wouldn’t hurt to check the gasoline filter, which is located in the tank, take it out and clean it if it’s dirty. If these measures do not help, then you will have to take Shtil to a specialist, which means something serious has happened.

AND world famous company Stihl releases a huge the lineup quality chainsaws.For domestic purposes and simple work, the Shtil 180 chainsaw was created, which showed excellent performance and reliability. All the best practices are used here German company, with a weight of 3.9 kg, the chainsaw easily performed work in the garden. Easy to trim small trees, branches, you can even prepare firewood. But any even the most high-quality equipment tends to break, and it happens that the Shtil 180 chainsaw does not start or starts with great difficulty. We tried to collect all the reasons and methods for repairing a German Stihl 180.

No spark

If the chainsaw does not start, and you have not experienced any particular difficulties before, the first thing to do is check the spark plug. There may simply be no spark between its electrodes; this can only be determined after removing the spark plug. We check its functionality; to do this, we stick the spark plug into the cap of a high-voltage wire, and place the metal side of the spark plug on the cylinder (or other metal object). Now we do several manipulations with the starter, and if during them no spark is observed, the problem is specifically in the spark plug.

Attention: Be sure to make sure that the ignition is on, otherwise the spark plug will not show a spark in any case. Also, to make sure that it is the spark plug and not the ignition coil that is faulty, take a similar spark plug and check for a spark on it. If present, the problem can be solved by simple replacement.

Ignition coil malfunction

Repairing the ignition coil is impossible; its design cannot be disassembled. But you can only check the performance of a part with a special device. If there is no spark to the spark plug, do not immediately blame the ignition coil; carry out diagnostics. Some people mistakenly run to the store for a new reel, so first make sure it’s broken and then make a new purchase.

Supplying fuel to the chainsaw

If the Shtil 180 does not start, there is a spark, then first of all we check the presence of fuel in the chainsaw tank. Of course, the problem is funny, but quite common. Next, we check whether fuel is entering the carburetor; to do this, you can disconnect the gasoline hose from the carburetor and pump in gasoline. After several manipulations, gasoline should come out of the hose, but not in a large stream, but in small jerks. If gasoline does not flow or flows poorly, the problem may be the following:

The fuel supply channel is clogged;

Z The fuel filter is directly damaged.

Check out the article where it is described. The described tips apply to Shtil 180.

As unusual as it may sound, even a too full fuel tank can cause this. At greater O m pressure may squeeze out the fuel hose or the necessary vacuum may not be created. Be sure to monitor the quality of the fuel used to proper operation Never leave a chainsaw with gasoline for more than 2 weeks.Long-term storage of fuel in the tank contributes to the creation of resins and the process of polymerization of components.

Faulty crankshaft bearings

If Shtil 180 does not start and the fuel is supplied correctly, you will have to look further, namely into the crankshaft. Its bearings tend to wear out, which is why backlash appears.and trying to shake the flywheel. The fact is that if there is backlash, the flywheel magnets are attracted to the ignition coil,or rather to her contacts.

Repairing and replacing bearings requires disassembling the engine, so this work performed only by masters or people with experience. You should not disassemble the engine if this is your first time.

Floods the spark plug

In some cases, the Shtil 180 starts and stalls, or does not start at all. Then we check the condition of the spark plug; it may be flooded.There can be two reasons for this “overflow” - improper starting of the engine when cold and a malfunction of the carburetor. We are trying to solve the problem with the following steps:

Remove the spark plug;

We turn the chainsaw over to the other side and wait until the excess fuel flows out;

To be sure, we pull the starter several times, so that gasoline will certainly come out of the cylinder;

We return the spark plug to its place, install the cap and try to start the engine again with the starter.
