Today, the production of units for agricultural and construction work There are many manufacturers involved, among which the most popular is equipment manufactured by Shtil. The high level of quality is not the only reason why the products of this manufacturer are popular in the market. This was also facilitated by the affordable price and optimal power, which models of this brand have.
It seems that many people have had to use a chainsaw of a similar brand. And not just to use, but to regularly perform a wide variety of work and make sure of the high performance characteristics of this tool. This proliferation of these products is no coincidence, given that in addition to power, this instrument stands out for its graceful design. However, you need to remember that this is still a technique with a limited service life. Therefore, every owner of such a unit at some point is faced with the need for repairs. Next we will talk about the features of repairing the Shtil 180 chainsaw.
General information
The characteristics of this saw are a reason to be proud German manufacturer. At the same time, the unit is a tool that is designed to perform a small amount of work. The tool is positioned for household use, which confirms the intensity of its use, which should not exceed 20 hours per month. Having such a unit at your disposal, it will not be difficult for you to maintain order in your garden, prepare firewood for the winter, and also clear areas. At the same time, he will be able to help you in solving other problems where there is no need to perform complex manipulations.
Main characteristics
The saw in question can be considered compact option, because its weight is only 3.9 kg. At the same time, it has a large capacity oil and fuel tank. The device performs its operating functions using a two-stroke engine, the power of which is sufficient to solve simple tasks. In addition to this, during operation this tool does not create much noise, the level of which does not exceed 98 dB. For ease of understanding, it is enough to say that human speech creates noise at a level of 76 dB.
- The Stihl 180 chainsaw has a power of 2.6 watts. In principle, this is enough, remembering that we are talking about a tool for household use.
- The oil tank capacity is 0.145 l, the fuel tank is 0.25 l.
- The tire provided by the design has dimensions of 350 mm, with a pitch of 0.325 inches.
Winding device
As with other saws, the carburetor plays the role of the main starting device. Looking in more detail at the carburetor that the Stihl 180 chainsaw is equipped with, it should be noted that it has a single adjustment screw. In other words, it is a kind of idle speed adjustment screw. In this case, the jet, which bears the full load, is motionless all the time.
In other words, the regulation is not applicable to him. In turn, there is no way to influence the full load in any way. You also need to pay attention to the factory settings, due to which the air supply fuel mixture carried out directly to the engine. Moreover, this principle remains unchanged regardless of the operating conditions of the tool.
The saw does not start: reasons and solutions
- Speaking about the 180 saw, it must be said that this tool has many advantages. At the same time, this unit is not without its shortcomings. They will receive attention.
- A common situation is that many owners find themselves in when the chainsaw does not start when it is calm and pours a candle. This is usually associated with the formation of a leak in the oil used to lubricate the chain. This happens for the reason that over time, the area where the hose of the oil pump and the oil tank connects loses its former tightness.
- In principle, this problem is solvable, but in order to do everything correctly, you need to take into account the design of the chainsaw in question. This process itself involves certain nuances; first of all, it is necessary to disassemble the unit, and without this it will be impossible to get to the required place.
- For many owners of this saw, the pressing question is why the Shtil 180 chainsaw won’t start? Experts give the following recommendation in this regard: the first thing to do for those who are faced with a similar problem is to open and then close the cap located on the gas tank. There is another solution - you need to pull out the candle and let it dry. You can also create an effect artificial ventilation for the combustion chamber. Most often, these recommendations are enough to bring the device back into working condition. However, this does not always help restore the chainsaw to calm operation.
- If there is a spark, but attempts to start the chainsaw do not lead to anything, then in this case you need check the gasoline supply, air filter, and then make sure the spark plug is in working condition. Such manipulations need to be done for the reason that most often this kind of malfunction is caused by contamination of the breather. And if a plug forms in it, then, naturally, a vacuum environment will be created in the gas tank, which is why fuel will not flow. A similar problem can be solved quite simply, for which it is enough to remove the dirt using a needle.
- Some owners encounter this problem when the saw itself starts up, but immediately begins to stall. The reason why the saw won't start should be found in the carburetor. Most likely, it has become clogged and therefore does not allow the tool to work correctly.
To make sure that the cause of the malfunction is not the breather and that it is in working order, you must first disconnect the fuel hose from the carburetor and then find out if there is a fuel leak.- Please keep in mind that it is natural for a chainsaw to operate normally. dense and stable stream of gasoline. In addition, you can often observe a situation where the Shtil 180 chainsaw does not start when hot and immediately stalls at the same moment or after some time. Usually such a malfunction is associated with the muffler. Most likely, it has accumulated a lot of deposits associated with long-term use of the tool, which is usually accompanied by the formation of exhaust.
- At the same time, the saw may stop starting if the tool chain is poorly lubricated. Channels that have a plug can contribute to this, or the cause should be sought in an oil line that has a leak.
- Leaks in the connecting pipes or at the installation site of the oil pump fittings can become a serious problem.
- There are cases when the Shtil 180 chainsaw begins to stall due to a failed cylinder. To make sure that this is really so, it is enough to conduct an inspection. If, as a result of the examination, you find unevenness and chips, then this is a clear sign of a breakdown.
Faulty spark plug: troubleshooting methods
Other faults
Conclusion
A chainsaw makes many tasks easier. However, for a long time she cannot demonstrate her original level of work. Therefore, problems may occur at some point. Naturally, the owner can fix some faults on his own, but in any case there is a risk that he will incorrectly identify them, and this is fraught with the fact that his actions can completely disable the tool. That's why it is advisable not to take initiative, and entrust this work to a specialist.
I have a Shtil-250, old man, a problem has arisen: when it’s cold it starts without problems, but when it’s hot you’ll start it until you burn the unburnt mixture through the muffler. I installed a new spark plug, washed and cleaned the filter, and also cleaned the carburetor. Still the problem remains, please tell me how to solve it?

Checking the muffler
Most likely, the reason lies in the muffler, which is clogged with combustion products (deposits) or simply debris. It is enough to clean it, and normal operation of the chainsaw will be restored. To do this, it is best to dismantle this part and wash it using ordinary detergents (aggressive ones are possible). Then rinse the muffler thoroughly clean water and dry with a hairdryer.
Cleaning the muffler usually has a positive effect
When cleaning, be careful: carbon deposits contain carcinogenic substances that, if they enter the lungs, can be harmful to health. The reason for the appearance of carbon deposits is the incorrect ratio of gasoline and oil poured into the tank. Most users prefer to do this “by eye”. But maintaining the exact proportions is not at all difficult: just use a disposable syringe without a needle of the appropriate volume.
Other reasons
Here, first of all, we mean wear of the cylinder, piston, rings, and crankshaft bearings. The failure of these elements ultimately leads to a drop in compression (pressure) in the cylinder. You can check the condition of the CPG at the same time when you remove the muffler. After dismantling this part, you will see a window through which part of the cylinder is visible. If nicks or scratches are visible on it, it will have to be replaced.
Parts for repair can be purchased in specialty stores or on the Internet.
Next you need to check the compression. If you do not have a special tool, remove the spark plug, plug the hole with your finger and pull the starter cord. At good blood pressure the finger will be sucked inside. If you have a compression gauge, you need to insert it into the spark plug hole. Also crank the crankshaft using the starter and look at the instrument readings. The normal parameter is 8-9 kgf/sq. cm (which corresponds to 0.8-0.9 MPa). The reason for low compression may not necessarily be a worn cylinder or piston: sometimes it is enough to replace coked rings.
Amateur and professional chainsaws are complex devices. The motor life of their two-stroke engines, components and assemblies has its limitations. For this reason, quite reliable and expensive tools, along with cheap Chinese units, periodically fail and refuse to start. The situation when a chainsaw does not start or stalls is not very pleasant and sometimes confuses the user. How to identify and eliminate the malfunction, restoring the functionality of the tool.
Identifying and eliminating obvious chainsaw faults.
To determine the reason why the chainsaw does not start or stalls when starting, it is necessary to troubleshoot the tool. The essence of the procedure is a sequential inspection of the condition and operation of the main working elements of the saw engine. At this stage we check:
- Presence of a spark on the spark plug;
- Fuel supply;
- Filter status;
- Operation of the breather built into the fuel cap of the stalling unit;
- Functioning of the exhaust channel.
Checking the spark on the spark plug and eliminating the causes.
The first step is to find the reasons why gasoline saw If it won't start, check the spark at the spark plug. There are many factors that influence the operation of this element. However, the main ones at the initial stage of tool troubleshooting are:
- Incorrect carburetor adjustment;
- The presence of more than the required amount of oil in gasoline;
- Air filter clogged.
All of them contribute to the formation of carbon deposits on the spark plug electrodes. In 50 cases out of 100, saws do not start when cold due to the lack of a spark due to carbon deposits on the electrodes and their corrosion. The result is either a decrease in the gap or an increase in it.
Checking the spark plug of a non-working chainsaw
Checking for spark is quite simple. To do this you will need:
- Remove the tip of the high-voltage wire;
- Unscrew the spark plug;
- Put the tip back on;
- Place the candle skirt against the cylinder;
- Start with the starter.
If at the moment the chainsaw engine starts, a good spark is observed between the electrodes, then everything is in order with the ignition unit. If it is not there, then it is worth cleaning the element itself and checking the electrode gap. If necessary, use a special probe to adjust the distance between the contacts.
By the candles different manufacturers the distance between the electrodes may fluctuate. For some it may be equal to 0.5 mm. Others have 0.2 mm. Therefore, carefully study the manufacturer's recommendations.
There may be no spark at the spark plug for other reasons. Of the main malfunctions that affect poor starting of the chainsaw and unstable operation of the internal combustion engine on Idling, which can cause the instrument to stall, include the following:
- Overfilling of the spark plug channel with fuel;
- Lack of contact between the high-voltage cradle and the tip of the spark plug;
- Failure of the ignition unit.
How to start a cold chainsaw if the spark plug channel is constantly flooded with gasoline? You can fix the problem while starting the tool using the following algorithm:
- Unscrew the spark plug with a special wrench;
- Wipe it with a clean and dry cloth;
- Dry for 20...30 minutes;
- Remove carbon deposits with a file and adjust the gap between the electrodes;
- Drain the remaining fuel from the spark plug channel and dry it;
- Collect everything and try to start the mechanism.
As a rule, these measures are quite enough to start the chainsaw and get the job done. However, this last resort does not eliminate main reason If the engine does not start or stalls, the carburetor is not working properly and needs fine adjustment.
If there is no spark due to poor contact of the high-voltage cradle with the tip of the spark plug, it is necessary to check the connection. The test can be carried out using a regular tester. If a defect is detected and corrected, the chainsaw should start without any problems.
If the check shows that the contact is reliable, but the saw still does not start, look for the reason in the ignition unit. As a rule, a faulty unit cannot be repaired or restored. This will require a complete replacement.
We determine the availability of fuel and its supply.
First, you need to make sure that there is a fuel mixture in the tank of the chainsaw that does not want to start, and that it is properly supplied to the carburetor. With a full tank, check how the mixture is supplied through the gas line. We disconnect the fuel system pipe from the carburetor and try to pump it up. When complete order, when pumping, gasoline will be supplied jerkily in accordance with the standards set by the manufacturer. Weak fuel supply or its absence can result from:
- The fuel supply channel is clogged;
- Fuel filter clogged with debris.
Often the cause of poor starting of a chainsaw can be a too full tank. In this case, you should pay attention to the presence of smudges under the saw housing cover. If they are present, then look at the connection of the gasoline supply pipe to the carburetor. Most often, it is squeezed out by pressure when screwing on the tank cap, which is tucked right under the neck, which prevents the engine from starting.
The quality of the fuel mixture can also be one of the reasons why the chainsaw does not start. If, after completing the work, you do not drain the remaining gasoline and leave the tool for long-term storage (more than 2 weeks), then the processes of resin formation and polymerization of the components will begin to occur inside the tank. What can cause carbon deposits to appear on the piston, rings and cylinder liner. Therefore, always prepare the mixture in only the required quantity before work.
Checking the condition of the fuel and air filters.
If the fuel quality is fine, the chainsaw engine may not start due to clogged fuel and air filters. To diagnose these elements, you will need to perform a number of manipulations associated with their dismantling.
For fuel filter:
- Disconnect the gasoline supply line from the carburetor;
- Pump up the fuel.
If there is little or no pressure in the pipe, disconnect the filter. Before doing this, empty the tank of the mixture and remove the filter element itself. Dismantling is done using a wire hook. Crowded replaceable cartridge, which caused the chainsaw engine to start poorly, can be cleaned, but it is best to replace it with a new one. When using the tool in dusty conditions, cleaning should be done on a regular basis.
A clogged air filter can cause the chainsaw engine to run rough, causing it to stall or be difficult to start. Dust and dirt deposited on the adsorbent material make it difficult for air to enter the system, making the fuel mixture so rich that it will sometimes be difficult to start the tool.
Checking the air filter is one of the first steps in finding the causes of poor starting.
Removing the air filter should be done with caution, since dust accumulated on its surface during operation of the saw can get into the carburetor. And this is fraught with more expensive repairs. After disconnecting the cartridge, thoroughly clean it of accumulated dirt and rinse with added detergent. Dry the element and carefully put it back in place.
Checking the breather and cleaning it.
The breather is another element, due to improper operation of which the chainsaw may not start or stall during the sawing process. This element is located on the fuel tank cap in the area of the air hole. This is a kind of valve that does not allow gasoline to leak out and equalizes the air pressure necessary for the free flow of fuel into the carburetor.
If the breather is dirty, the running chainsaw stalls, and when started, it refuses to start. The whole point is that air stops flowing through the hole. As a result, negative pressure (vacuum) is created inside the fuel tank, preventing the flow of gasoline to the carburetor.
Identifying the problem is quite simple. Disconnect the fuel supply hose from the carburetor and see what happens to the gasoline. If it flows freely in a good stream, then everything is in order with the breather. If it is absent or it flows weakly and intermittently, then the cause is identified - the breather is clogged with dirt. The problem can be solved by cleaning the air hole with a regular needle or a powerful jet of compressed air.
Checking the exhaust channel of the chainsaw.
One of the reasons that a chainsaw is difficult to start may be a clogged exhaust channel or its muffler. At the same time, there is a drop in power during sawing of lumber and logs. Most often this occurs due to tarry deposits on the spark arrester or muffler channel, which are formed during the combustion of a low-quality mixture of gasoline and oil, preventing the exhaust gases from being vented.
A resonator clogged with carbon deposits can cause a gasoline saw to start poorly.
Eliminate the cause of poor starting of the chainsaw, in in this case, you can remove accumulated combustion products. To do this, perform a number of manipulations:
- Remove the muffler by unscrewing the screws;
- Remove the cooling panel and sealing gasket;
- Remove the spark arrestor;
- Disassemble the resonator body;
- Wash all elements from carbon deposits using detergent;
- Let them dry completely;
- Reassemble everything in reverse order;
To prevent dust and sand from entering the cylinder when cleaning the muffler, cover the exhaust duct of the chainsaw engine with a clean rag.
What to do if the chainsaw continues to not start?
If the initial inspection did not yield anything or the defects were eliminated during the search process, but the chainsaw still does not start, then you need to search more serious reasons. It is best to identify and repair such breakdowns at a service center. However, if you have experience, you can find and eliminate them yourself. What to diagnose and check?
- Compression in the cylinder;
- Compression in the crankcase;
- Carburetor operation.
In the first case, checking the compression in the cylinder will allow you to find out the condition of the cylinder-piston group (CPG) of a chainsaw that does not want to start when cold. To do this you need a compression gauge. The device is screwed into place of the spark plug and the engine is started idle. Measuring the readings allows you to judge the condition of the CPG. In the absence of a compression gauge, you can determine the compression in the cylinder offhand as follows:
- Place your finger on the spark plug hole;
- Try to start the chainsaw engine.
By placing your finger on the spark plug hole and pulling the starter, you can check the compression in the cylinder
If you feel that your finger is being pulled strongly into the spark plug channel, then everything is in order with compression. The absence of vacuum in the chamber indicates a malfunction. The cylinder-piston group needs a more detailed inspection, which will give an idea of the condition of the piston and cylinder, piston rings and bearings.
A chainsaw may not start when cold due to a lack of compression in the engine crankcase. The main reason for this is damage to the gasket located between the cylinder and the crankcase. It is quite easy to detect a lack of compression:
- Disconnect the upper tube from the carburetor;
- Pour gasoline into a regular cork;
- We immerse the removed tube in the fuel;
- We pull the starter several times.
If fuel is sucked out of the cap when the chainsaw starter starts, then everything is fine with compression. If not, look at the gasket.
If the fuel is drawn in, then everything is fine - the gasket is intact. Otherwise, you will have to purchase a repair kit and make a replacement. How to do this, watch the video why a Chinese chainsaw won’t start:
Starting the tool may be complicated by improper operation of the carburetor or its breakdown. It often happens that during the sawing process the fastening screws become loose and air is sucked into the cylinder. Check that the carburetor is securely fastened. Inspect it for fuel leaks. There can be many reasons for the malfunction. It is possible to accurately determine the malfunction, eliminate it and fine-tune the carburetor only at a service center.
After going through a step-by-step troubleshooting of the chainsaw engine, you will be able to find the malfunction, fix it yourself and successfully start your working tool. Do not take on types of work that you are not confident in. Entrust troubleshooting and troubleshooting to specialists from the service center.
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 is longitudinal stripes then replacement is required.
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: The standard length of the MS 180 tire is 35 cm, it is possible to cut a log of 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 not designed for this, you (in best case scenario) we reduce the resource 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 towards the muffler or vice versa? chain saw Stihl 180 C?
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 moving the lever 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) is 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 expense chains. Still, 1.1 has a shorter tooth (and on some models, much shorter), resulting in fewer sharpenings.
Help please | Topic author: Fatima
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 run in at idle, 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 sawing!) at first the smoke will come out and black slurry will fly from the muffler, in your case this is normal)) and no idle, no need for a saw - muffle it.
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 a Chinese Husqvarna type saw, so 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 oil be left in the tank for long-term storage? 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 saw 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

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 optimal pricing policy and the 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 moths of this manufacturer, namely the Shtil 180 chainsaw. chainsaw stihl ms 660 read here. So let's get started.
Briefly about the main thing
This model is the pride of the German manufacturer and is a direct tool intended for minor 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. The manufacturer has equipped this device with a two-stroke engine with sufficient 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 volume itself, just compare its noise with colloquial speech, which has an indicator of 76 dB.
The power of this model is 2.6 W. It is worth noting that this is a fairly significant level of power, considering that it is not 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.
- A fairly common problem is that the Shtil 180 chainsaw does not start and the spark plug floods. 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.
- 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 of 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.
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:
Chainsaw chain lubrication
- Connecting pipes or the connections themselves in the area of the oil pump fittings may also leak.
- 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 are empty. 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 it is repaired by specialists, since if you have the 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 doing? 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 the oil is of 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 you saw for a long time was filled with gasoline, but did not start, then pour the old gasoline out of the tank and pour new one, the first time the saw will not start very quickly, and 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 Gas engine A chainsaw is not much different from a car engine, and if it doesn't start, it needs to be rebuilt, worst case scenario.
Chainsaw – worthy replacement hand saws and axes. Today this tool is available in almost every household- it is indispensable when arranging personal plot, construction and repair work. Intensive use and improper care of the tool can lead to premature failure. However, it is not at all necessary for the owner of a chainsaw to immediately contact a workshop - many of the malfunctions that can happen to it during operation can be easily eliminated on their own.
Chainsaw design and general classification of faults
The main condition for successful repair is correct. Therefore, in order to determine why the chainsaw failed and, most importantly, how to make it work again, you first need to know the features of its design.
It should be noted that it is not particularly complex, as it includes:
In order to simplify the diagnosis of faults, they are usually divided into two main categories:
- engine malfunction;
- malfunctions of other chainsaw components.
Most often, failures occur in, however, other parts of the tool due to intensive use or improper care may fail at any time. How to determine exactly where the breakdown occurred? Simple logic will help us with this.
If the problem is in the engine, it will:
- won't start;
- stall;
- work unsteadily;
- overheat;
- smoke;
- develop insufficient power.
As for all other faults, as a rule they manifest themselves when the engine is running normally.
Starting the engine: checking the spark plugs
If the chainsaw does not start, the first thing to do is check the tank for . By the way, it must be prepared in the proportions specified by the engine manufacturer, otherwise the tool simply will not start. 
After making sure that the fuel mixture is correct and available, you should check the ignition system. To do this, you need to inspect the spark plug.
Her condition can say a lot:
- dry candle
indicates that the fuel mixture does not enter the carburetor, which means the problem is not in the ignition;
- fuel-spattered candle
is the result of an excess of the fuel mixture, which lies either in a violation of the engine starting algorithm or in incorrect carburetor adjustment;
- carbonated candle
This is a signal about the presence of low-quality oil in the engine lubrication system, incorrect carburetor settings, or an incorrectly prepared fuel mixture. 
If it is splashed with fuel, it must be thoroughly wiped after removal. The fuel supply system should also be cleaned. To do this, it is closed, after which the starter is turned on. A candle covered with soot must be carefully cleaned using an awl and sandpaper.
When checking spark plugs, you should pay attention to the distance between the electrodes (the normal gap is 0.5-0.65 mm), as well as the condition of the gasket and the presence of a spark. A damaged or worn gasket will need to be replaced, and the spark can be checked by putting on the ignition cable, connecting the cylinder and spark plug nut, and turning the starter.
If the discharge does not occur, the spark plug needs to be replaced. If a spark does not appear even with a new spark plug, then the problem is in the connection to the high-voltage wire or in it itself.
DIY chainsaw repair: fuel supply system
If the fuel mixture does not enter the cylinder, but the spark plug works normally, this may mean that:
- The fuel filter is clogged.
To clean this unit, remove the fuel hose and check the flow. If it is weak, the filter must be removed through the filler hole of the fuel tank and cleaned or replaced if completely worn out. 
- The breather is clogged.
This is nothing more than a hole in the fuel tank cap, which is cleaned with an awl.
- The fuel mixture is not supplied or is supplied in insufficient quantities.
There may be several reasons for this:
Troubleshooting muffler problems
If it works fine at low speeds, but starts to stall and smoke at high speeds, the problem may be hidden in the muffler.
To check the quality of its work you should do the following:
Dry cleaning without respiratory protection is not recommended. Carcinogens present in carbon deposits will be released into the surrounding atmosphere in the form of dust, the inhalation of which is extremely hazardous to health.
To prevent clogging of the muffler during operation of the chainsaw, you should carefully monitor the composition of the fuel mixture and the quality of its components.
Repair of cylinder-piston group (CPG)
If the chainsaw engine does not start or cannot develop normal power, it is likely that there is not enough pressure in the engine cylinder to burn the fuel mixture. The reason for this may be wear of elements - piston, rings, bearings, etc. In order to assess the condition of this unit, it should be checked visual inspection after removing the muffler. 
For a more complete diagnosis, a compression gauge is placed in the spark plug hole of a two-stroke chainsaw engine. It is used to measure compression in the engine. Based on the results of the inspection, one can judge the condition of the CPG, but accurate facts can only be obtained by complete disassembly node.
If the piston is chipped or scratched, it will obviously have to be replaced. The same applies to deformed or broken piston rings - for normal operation engine, they must be in full working order and free of carbon deposits.
Checking the carburetor and signs that it needs adjustment
Correctly working guarantees maximum efficiency operation of a chainsaw, that is, it is possible to develop full power at the most economical consumption fuel mixture. Adjustment of this unit is usually carried out by the manufacturer, but its design provides for the possibility of adjustment during operation.
The fact that such adjustment will have to be made by the owner of the chainsaw is evidenced by:
- Strong vibrations or damage to the protective cap.
- CPG wear.
- Carburetor clogged.
- Inability to start the engine or its spontaneous stopping after starting.
- Increased fuel consumption and exhaust emissions with a simultaneous decrease in engine power.
The chainsaw carburetor is adjusted in strict accordance with the manufacturer’s instructions using three special screws, which are responsible for the maximum (“M”) and minimum (“L”) speeds, as well as engine idle speed (“T”). In order to exclude unwanted interference by an inexperienced user in the operation of the carburetor, some manufacturers install only one idle screw. 
Calibration algorithm and safety precautions when troubleshooting a chainsaw carburetor
Carburetor adjustment is performed in two stages:
- Basic (carried out with the engine off).
- Finish (carried out with the engine running, preheated).
For basic adjustment It is necessary to tighten screws H and L until they stop and turn them back 1.5 turns. Final adjustment requires that the engine be warmed up for 5-10 minutes at low speeds.
The finishing is performed by turning out the idle screw until the minimum engine speed is reached (its operation must be stable and the chain must be motionless). If the engine stops idling, the propeller must be returned, and if saw chain is still set in motion, you should continue turning it counterclockwise.
Calibration check is performed by test:
- Acceleration (when you gently press the accelerator, the engine should quickly gain speed to its maximum).
- Maximum speed (if there are misfires, screw H should be loosened slightly).
- Idling (the chain should not move, and the engine should pick up speed as quickly as possible).
If the owner of the chainsaw is not familiar with the carburetor structure and does not have the necessary tools to calibrate it, you should contact a specialist. Carburetor - very complex knot, therefore, any incorrect action can lead to irreversible consequences, such as complete failure of the engine.
Other chainsaw malfunctions
If the diagnostics showed that everything is in order with the engine and its systems, then the cause of the malfunction should be sought elsewhere. The most common problems are:
If the cause of tool failure is not visible to the naked eye, as is the case with the engine, it is necessary to carefully diagnose the faults and eliminate them in accordance with the manufacturer's recommendations and safety regulations.
