Malfunctions of the Shtil MS 180 chainsaw and their elimination
The Shtil MS 180 chainsaw is in operation. There is a problem in the future. Before storing it for the winter, on the advice of the mechanics, I dropped 4 drops of motor oil (calm) into the spark plug hole. screwed the candle. Chain for chainsaw stihl ms 180 from $10. Company SP Savitsky A. To bizorg.su, id 1109322. At the moment I was getting ready to go to the dacha, I decided to take a look at the saw. I pulled the starter, but it wouldn’t turn! I turned the spark plug out, it was covered in oil, wiped it and put it back. the same. I turned it out, cranked the starter without a spark plug - everything turned completely. I screwed it back in and the starter doesn't turn. What could it be?
Rinse the chainsaw with clean, undiluted gasoline, pour it directly through the spark plug hole and slowly crank the starter. Later, drain the fuel and use the new one. After all these manipulations, dry the saw and spark plug and only then try to start it. Once you have learned how to preserve, then learn how to re-can it, and don’t just pull it and go.
Tell me, why might the starter stick? The Stihl 180 chain saw is brand new.
If you don't understand, you won't recognize it. Maybe the starter cord is poorly laid out, or maybe the tide is interfering somewhere. Shtilev starters are quite reliable and durable. Any diseases constructive plan not observed, mainly either dirt or intense exploitation. If your chainsaw is brand new, take it to a service center and they will repair it under warranty.
I'm at my own chain saw Stihl MS 180 saw one feature: when the tank runs out of gasoline, the revolutions idle speed increase and the chain begins to spin even when the trigger is released. When you press the gas, the chainsaw stalls. This continues for a couple of 10 seconds, then the chainsaw stops. In motor vehicles, I have not observed such a phenomenon, so that when there is a shortage of fuel in the carburetor, the engine speed increases. Why is this happening?
This is a common occurrence with two-stroke engines. When the supply of gasoline to the carburetor is reduced, the consistency becomes leaner. As a consequence. increased speed, worse acceleration. This is accompanied by short-term overheating of the CPG. It won't damage the engine, but it won't improve your health. Avoid running out of fuel completely from the tank.
There is a Stihl MS180 chainsaw, used in summer season on the preparation of firewood. Soon the reaction of the chain began to disappear when pressing the gas; the chain did not rotate at all, or jerkily. sawing is unrealistic. What could be wrong?
For a completely new chain and sprocket, the tension should be exactly according to the instructions. so that the lower branch does not sag. and the upper one could be pulled out with your fingers to the height of the leading link. Then the chain will move quite freely along the tire. But, the gradual wear of the sprocket teeth reduces its pitch. And the gradual stretching of the chain increases its pitch. and the time comes when the steps of the same sprocket and chain cease to coincide to such an extent that the recommended tension already causes difficulty in moving the chain. IN in this case We recommend reducing the tension a little. Right before there is some sag in the lower branch. By the way, for the same reason it is recommended to use a pair, or even three chains on one sprocket. In this case, wear is moderate and there will be no accelerated wear of the new chain on an old, partially worn out sprocket.
The Shtil 180 chainsaw "chokes" after starting when you press the gas, but as soon as you start sawing it stalls. But if you torture it with gas for 30-40 seconds, it starts working normally. I used up 3 liters of gasoline, the filters are clean, the oil is from the dealer.
If this started not long ago, then most likely something got into the carburetor with bad fuel. Needs to be cleaned.
I would like to purchase this unit. What should you pay attention to during the inspection?
Not to mention the engine itself, since it is better to diagnose it in a service center, you can look at the rest and get a lot of information. Significant mileage will be indicated by: A loose latch of the top cover. (Should lock tightly and not rotate due to vibration). A brand new sprocket on a battered chainsaw. If during operation there is no oil supplied to the chainsaw chain, you need to look for the cause of the problem. When the cover is removed, the motor moves relative to the housing. Sheared chain catcher and chain damage on the sprocket cover. You can also take a close look at the carburetor on the left side along the way. the place where the wire rod enters the choke shaft arm. On a chain saw that has been used slightly, it will be even and oblong. The longer the saw has worked, the larger the hole will be. From time to time it gets wiped clean. Under no circumstances should you take a saw that has even a small amount of free play on the right end of the crankshaft relative to the engine. This is a sign of a quick renovation.
How many seconds should the Shtil ms 180 chainsaw engine run at idle before turning it off?
Let it run for about 20-30 seconds and then turn it off. More. there's no point.
The idle speed started to disappear, at first I didn’t understand what was wrong, but later I remembered that I needed to increase it a lot idle speed I added it on a hot engine and it seemed to work out. I arrive at the dacha in a week and need to cut a couple of logs, I start the saw and at first the chain spins on a cool engine, then everything goes away, after standing for about 10 minutes I start everything fine only on a cool engine. This is fine?
If the chain turns, the speed is too high. It should be understood that a normally adjusted and serviceable engine is likely to have a slightly higher idle speed immediately after starting before warming up. And he can be promoted decently. before the chain rotates. As the engine warms up, the idle speed gradually drops. For this reason, it is recommended to adjust the idle speed only when the engine is warm.
Is it possible to install a clutch drum with a removable ring on a Stihl MS 180 chainsaw ("upgrading" the drum is allowed), for example from the 250th.
Read:
Can. Everything fits perfectly. Just don’t go over 325". This is hard on the motor. But a couple of aspects should be taken into account. On such a set (with a removable one), the sprocket is a little larger in diameter and one tooth larger. The speed of the chain will increase in the proportion of 6:7, and accordingly, it will also increase load on the engine. But practice has shown that this is not critical with normally sharpened chains. And a completely new chain of 50 links is difficult to put on such a sprocket (in general, 51 links are recommended, but they rarely happen). Once you have to suffer so that she stands on the sprocket and splint, and later, when she stretches a little, everything will be fine.
I bought a Shtil 180 chainsaw. I filled it with oil and benzyl. Started it up and let it run without any load on it. idling. I burned a tank of gasoline and periodically pressed lightly on the gas. For some reason, the oil to lubricate the chain never arrived; the oil hole remained dry. If during operation there is no oil supplied to the chainsaw chain, supply oil to the chain. Or will it start to flow when the revolutions are higher and the chain spins longer?

Diagnostics of the chain lubrication system of the Stihl MS180 chainsaw
I'd look at the muffler. If it has not been cleaned once in 6 years, it becomes clogged and the exhaust gases have nowhere to go. Usually, with such symptoms, either the air filter or the muffler is clogged.
I recently learned that it is advisable to turn the tire over on a chainsaw from time to time. for even wear. Tell me, is this so, is it worth doing?
Rotating a tire isn't just advisable. Necessarily. How often? depends on the amount of work. Not only turn it over, but also grind off the burrs.
What is the difference between the drive and chain sprocket of the Stihl 180 chainsaw?
There is no difference between a “drive sprocket” and a “spin wheel”; these are different names for the same part.
I bought this chainsaw, I really liked it, but I want to ask you, can my saw cut thick wood?
Standard tire length. 35 cm, it is possible to saw a log. 70 cm in diameter, if logs of this diameter predominate, then you need a chainsaw of greater power. The tool will, of course, cope with the task, slowly and surely saw all the logs 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 service life of the chainsaw, that is, we bring its major repairs closer.
Please tell me, is it possible to use a 45 cm guide bar on a Stihl 180 chain saw?
You can put a tire on the chainsaw maximum length 40 cm.
Where is the breather located in the Shtil ms 180 chainsaw?
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.
The gas button gets stuck in the horizontal position. What to do?
Most likely, the lever-traction mechanism is faulty; when the unit is turned over, one of the levers or rods “falls”.
Why is oil not supplied to lubricate the chainsaw bar? What's the problem?
The oil filter is clogged. The channel in the chainsaw body is clogged. The tire channel and groove are clogged. The Husqvarna chainsaw chain is not lubricated. The oil pump drive (worm) is faulty. Oil pump is faulty. The oil tank has run out of oil.
What can you say about the chainsaw engine overheating? Calm 180?
I will try to explain about overheating of a working chain saw. I understand a working chainsaw this way: the carburetor is correctly adjusted (it is enough to set the idle speed to normal, by ear or on the tachometer 2800), bearings, seals, filters, spark plug. in order. The cooling system must also be in order, otherwise it happens that you can’t see what color the starter cover is, the grille is clogged, and almost no air flows through. If a working chain saw runs on a normal fuel mixture (high-quality gasoline with a sufficiently high octane number, good two-stroke oil and its correct proportion). then it is practically impossible to overheat (sharp chain. goes without saying). The cause of overheating is directly related to fuel; you can overheat a new saw in 5 minutes, and a working one at that. Cause of overheating. not the work or its duration, but the fuel or oil. Or both. And with moderate home use, subject to all of the above, this instrument will never overheat.

Not everything is so simple -) What remains to be done for our client, he did it as in the video, alas, just like others, it did not help - (Damn, I took it apart a couple of times, our client has already reviewed it... The pump itself is spotless, the coarse filter and the hose too, I filled the oil supply hole in the housing with air and blew it out, our client is left to vent. At the moment, I filled the car with 10/40 clean oil and nothing squeezes out a single drop - ((Before that I changed the breather, the old one flew away somewhere, I was thinking about it on a personal computer The thing is, even with the lid open, the oil doesn’t flow at all. All that’s left is to pull out the reservoir completely and look, maybe where is the hole? In general, I’ll probably have to go to the service department - ((Sell when the pump is simply removed without this washer and nuts, just screw in the pin and rest against it with the platypus). a little on the body, pull it up, it jumps out of there itself-)

I also want to thank you for this video. It was VERY helpful to repair the saw’s lubrication system, and at the same time I learned how to disassemble and reassemble, without “excessive spare parts,” and I hope it is not an exaggeration to say to master Bravo for his sensible and accessible explanation.
Valery Chirko
The creator forgot to say that in order to install the pump, there is a mark on the saw body to which it is necessary to orient the oil intake channel, not only strictly in the opposite direction.

hello, I would like to thank you for this video, at first I saw this video six months ago, I am one of the convicts, I was assigned to a sawmill to dismantle a slab, we have ms 180 calms, what I saw were sagging dry chains, before I arrived, they were pouring out labor here To lubricate the chain, plus before opening the chain lubrication barrel, sawdust was not blown in, the result was a clogged oil pump channel, I had not climbed into saws before. After watching your video, I slowly began to repair saws, thank you very much for the push in my current life, I acquired another profession and get money for it, I repair not only the piston system. With respect to your apartment, Evgeniy.

Hello Evgeniy. I have this question. I changed the oil hose and put it on sealant. However, in any case, podiotsa oil has bubbles. Tell me what the problem is. Maybe in the pump?
I was too lazy to take it apart. The nozzle of a disposable syringe was inserted into the oil supply hole on the chain (I filled the syringe with gasoline). After several sharp pushes of the syringe piston, the oil supply to the chain was restored.

I have nothing against the fact that craftsmen like you demonstrate to others how to repair a complex mechanical unit with an internal combustion engine at home, it’s not an easy job for me, but the delicate pressing of an oil pump without special tools leads to greater wear on the worm (due to some /- 1-2 mm normal), actually tested)))

Loved the video!! Thank you! In my opinion, there is no more detail, what remains for our client to do in reality and nothing personal!!

Please tell me what should I do, you don’t seem to have enough oil, but I have quite a bit of oil in my field.

Have a nice day! Who has a 180th calm, tell me what is your oil consumption for lubricating the chain while the saw is running? For some reason I have it big (when burning a tank of gasoline, the chain lubrication tank is almost completely empty). Is this normal operation of the chain lubrication accounting system or is it not working correctly? Thank you!

Why not oil comes in on a chainsaw chain?
If during work there is no oil comes in on the chainsaw chain, you need to find the cause of the problem. In fact, there are many reasons that influence the myth process. You should disassemble the chainsaw and identify main problem. The probable prerequisites for this process will be described below.
There are several reasons for the lack of oil supply to the chain during operation of the chainsaw; to identify them, you need to disassemble the chainsaw.
Possible reasons for fuel failure
Oil may not flow to the chain only if there are two breakdowns. These include:
- problems with air leaks;
- drive failure oil pump.
The main characteristics of a chainsaw chain.
The main cause of failure is air leaks. This can happen due to depressurization of the oil hose during operation of the chainsaw. In such circumstances, you need to remove the hose from the hole. This must be done in the area where it is connected to the crankcase. Then the hose is seated on the sealant and installed in its normal position. If this does not help, most likely, elasticity has been lost. For future use of the chainsaw, it is advisable to change the hose.
2nd reason - drive failure oil pump. In common parlance this part is called a worm. When the drive fails, the oil supply to the chain will stop. The oil pump drive is a round plastic ring with grooves inside. The constant use of a chainsaw leads to wear of the internal parts, and as a result, the iron hook located inside the drive breaks. After this breakdown, oil stops flowing to the chain.

Chainsaw fuel system: 1 – fuel filter, 4.5 – carburetor, 3 – hand pump preparatory swapping.
If the carburetor is adjusted correctly, fuel will be consumed in the permissible amount. Otherwise, it will end very quickly.
Slowly reducing fuel in your operating time sawing is a common process. If it is missing, the chain is not lubricated correctly, so working with the chainsaw will be smooth. It is necessary not only to be able to eliminate breakdowns, but also to identify them without the help of others.
There is an option to change the fuel supply manually. The correct operation of the lubrication complex of accounting programs is determined by the method of applying the tire. If oil splashes appear, it means that all that remains for our client to do is set it up correctly.

It is better to create a cut with a significant amount of lubricant. If you have to work with soft wood, a small amount of fuel is supplied.
The chain can always be perfectly lubricated. This will avoid smoke and future failure of the entire chainsaw. If oil leaks or does not flow at all, you need to identify the cause of the breakdown. It is not recommended to operate the tool until repaired.
When choosing fuel, you need to do it right. The desire to save leads to the fact that the chain quickly burns out. To avoid negative consequences, you do not need to choose oil produced in China. Preference should be given to unusual companies. On your own price category They are significantly higher, but their quality is better.
Troubleshooting Chain Service Issues
During the operation of the chainsaw, you need to constantly monitor the lubrication of the chain. Because this part works in the most demanding conditions. The chain is constantly overheated, dust and abrasive particles become clogged there. This negatively affects its service life. The situation will be corrected by a special lubricant. It is supplied to the chain from the tank, thereby ensuring unhindered operation.
If in your operating time There is no lubrication and there is a high risk of overheating. When there is no oil flow, the chain begins to stretch. At the same time, the possibility of its jamming or spontaneous jumping off remains, and as a result, a person can receive severe injury.
The channels through which fuel is supplied can become clogged with small particles, so it is advisable to clean them from time to time. It is also important to monitor the oil level in the tank. Debris in the channel often causes the chain brake to fail. This could have a negative impact on your work.
Regular cleaning of the channels and general care of the chainsaw will allow the tool to work for a long time.
If during operation there is no oil supplied to the chainsaw chain, you need to look for the cause of the problem. In fact, there can be many factors influencing this process. You should disassemble the chainsaw and identify the main problem. Possible reasons This process will be described below.
The reason for the lack of oil supply to the chain when the chainsaw is operating can be due to several factors, and to identify them, it is necessary to disassemble the chainsaw.
Possible reasons for fuel failure
Oil may not flow to the chain only if there are two breakdowns. These include:
- problems with air leaks;
- failure of the oil pump drive.
The main cause of failure is air leaks. This can happen due to depressurization of the oil hose while using the chainsaw. In this case, it is necessary to remove the hose from the hole. This must be done in the place where it is connected to the crankcase. Then the hose is seated on the sealant and installed in its usual position. If this doesn't help, there's likely been a loss of elasticity. For further exploitation chainsaws, it is advisable to replace the hose.
The second reason is a breakdown of the oil pump drive. In common parlance this part is called a worm. When the drive fails, oil will stop flowing to the chain. The oil pump drive is a round plastic ring with grooves inside. Constant use of a chainsaw leads to wear of the internal parts, resulting in a split. metal hook located inside the drive. After this breakdown, oil stops flowing to the chain.
You can troubleshoot problems yourself or under the guidance of specialists.

Fuel tanks are selected exactly according to volume. At maximum output, it is permissible to select components with a small amount of oil.
Chainsaw fuel system: 1 – fuel filter, 2 – carburetor, 3 – manual pre-priming pump.
If the carburetor is adjusted correctly, fuel will be consumed in the permissible amount. Otherwise, it will end too quickly.
A slow decrease in fuel while the saw is in use is normal. If it is missing, the chain is not lubricated correctly, so working with the chainsaw must be smooth. It is necessary not only to be able to fix breakdowns, but also to identify them yourself.
You can change the fuel supply manually. The correct operation of the lubrication system is determined by holding the tire up. If oil splashes appear, then everything is set up correctly.
It is advisable to make cuts with a significant amount of lubricant. If you have to work with soft wood, a small amount of fuel is supplied.

Troubleshooting Circuit Problems
During operation of the chainsaw, it is necessary to constantly monitor the lubrication of the chain. After all, it is this part that works in the most difficult conditions. The chain is constantly overheated and dust and abrasive particles become clogged with it. All this negatively affects its service life. A special lubricant will correct the situation.

If lubrication does not occur during operation, there is a high risk of overheating. When there is no oil flow, the chain begins to stretch. At the same time, there is still a possibility of it jamming or spontaneously jumping off, as a result of which a person can receive serious injury.
The channels through which fuel is supplied can become clogged with small particles, so it is advisable to clean them periodically. It is also important to monitor the oil level in the tank. Debris in the channel is a common cause of chain brake failure. This may have a negative impact on your work.
Regular cleaning of the channels and general maintenance of the chainsaw will allow the tool to function for a long time.
But what to do if all the recommendations are followed, but the oil still leaks. You need to make sure proper operation chainsaws. It is likely that it was assembled incorrectly. If the breakdown has not been identified, it is recommended to take it to a workshop. In some cases, it is necessary to replace the pump, but this should be done if the saw is new. Old tools leak due to worn out reservoir.
Only a specialist can assess the current condition of the chainsaw. In the absence of knowledge or uncertainty about own strength It is advisable to entrust instrument repair to a professional.
