The Stihl 180 chainsaw does not develop speed, or after you release the gas trigger, it continues to work without slowing down. These problems are quite common. Let's try to understand the reasons that result in the occurrence of such malfunctions. Also in this article we will look at how to diagnose if the chainsaw does not pull.
There may be several reasons for the lack of traction and poor speed of the chainsaw. Therefore, you should not immediately start disassembling and repairing the carburetor, since the reason may not be hidden in it.
The Shtil MS 180 chainsaw is equipped with a reliable carburetor, on which the manufacturer has limited the ability to adjust the power and maximum engine speed, so if the chainsaw loses traction, the carburetor is the last place to look for problems.
Muffler
You may ask, which is the first? The answer is a muffler. The muffler is responsible for exhaust gases and extinguishing the flames in them. All combustion products pass through it, which can clog it over time. The situation with a muffler clogged with soot is far from uncommon, and it occurs due to an incorrect fuel mixture.
With a normal ratio of gasoline to oil, combustion products are not so saturated with soot that they clog the muffler. If the amount of oil is more than normal, excessive carbon deposits will form during its combustion. Further, carbon deposits accumulate under the piston rings and in the muffler of the Stihl 180 chainsaw. Thus, a coked muffler is the most harmless thing that can happen, the maximum damage from excessive carbon deposits is the need to replace the piston.
How to check the muffler
To check the muffler, it must be removed from the chainsaw. To do this, using an 8 mm socket, unscrew the two fastening nuts and remove the part.
Important: after the muffler is removed, it is necessary to check the integrity of the gaskets between it and the cylinder, since very often they stick and break when the muffler is removed.
You can clean the part mechanically, using screwdrivers or a knitting needle, and then blow it thoroughly with compressed air. The seat on the muffler can be cleaned sandpaper to remove burnt parts of the gasket.
The muffler must be installed in the reverse order.
Important: when tightening the muffler mounting nuts, do not over-tighten the nuts, as the threads on the screws can be stripped.
The second reason why a calm chainsaw engine may reduce power and not develop speed is a blockage in the fuel system. As a rule, the first place to start looking for a blockage is the fuel filter.
Checking the fuel filter
The fuel filter is installed in the tank of the Shtil 180 chainsaw, and it is not very convenient to remove it. To make the process easier, you can take a small piece of aluminum wire and bend it at the end, then use it to hook the fuel hose and remove it, along with the filter, from the tank. To check the filter, you need to blow into it; if air does not pass through, then the cause has been found, and the filter needs to be replaced.
If the filter is clean, you need to check the fuel hose for clogging. To check, you need to disconnect it from the carburetor and, with the air filter removed, blow into it. If a blockage is detected, you can clean the hose mechanically, using a wire, and then blow it out with compressed air.
Strainer in carburetor
The last likely place for a blockage to form is the strainer in the carburetor. In the diagram below, it is indicated by the number 13.
In order to clean the mesh filter, you need to remove the carburetor from the Shtil 180 chainsaw. The work begins by removing the top cover of the saw, after which, using an 8 mm socket, unscrewing the two fastening nuts. Next, the filter housing is removed from the guides, after which the air damper rod and the engine control lever are disconnected. Lastly, the fuel hose and throttle linkage are disconnected, after which the carburetor can be removed from the guides.
Carburetor strainer installed in chamber fuel pump, in order to get to it, one screw securing the pump cover is unscrewed and it, along with the gaskets, is removed.
The mesh filter can only be cleaned using compressed air. Any mechanical methods are strictly prohibited, because the mesh is very soft and easily changes shape. When you press it, it easily wrinkles and bends form along the edge of the seat, through which unfiltered fuel can enter the carburetor.
During the cleaning process, the seat with the filter installed in it must be half covered with your finger and only then blow with air, otherwise the mesh may fly away and it will no longer be possible to find it.
Carburetor depressurization and nozzle blockage
Sometimes, when the screws securing the carburetor cover are loose or the gaskets have become unusable, the chainsaw may also experience a loss of power. To eliminate the possibility of this malfunction, it is necessary to check the integrity of the gaskets and the tightness of the screws on the carburetor covers. To do this, you need to remove it from the engine (the algorithm is described above) and disassemble it. Defective gaskets must be replaced using spare ones from the repair kit for the Shtil MS 180 carburetor.
In the case where a complete check of the fuel supply and exhaust gas system has been carried out, but there are no results. The main fuel injector valve needs to be checked. To check, you need to knock it out of the carburetor body. All work should proceed according to the following algorithm:
- The carburetor is removed from the chainsaw.
- The four screws securing the cover with the compensator are unscrewed, after which the cover can be removed.
- The carburetor is installed on a wooden lining, after which, using a bolt with a diameter of no more than eight millimeters and a length of 50, it is knocked out into the internal cavity of the carburetor.
- Next, you need to select a small hose, the inner diameter of which matches or is slightly smaller than the outer diameter of the nozzle and put it on the nozzle.
- The next step is to blow inside the hose. If it only blows in one direction, the nozzle is working properly; if it blows in both directions or does not blow at all, then the valve needs to be replaced.
All of the above actions should help in eliminating the problem associated with the fact that the chainsaw does not pick up speed, otherwise, a full diagnosis at the manufacturer’s service center will help.
Why does the chainsaw not slow down?
There may be several reasons why a chainsaw does not slow down:
- throttle spring broken;
- jamming of the gas trigger;
- the throttle linkage is bent;
- The corkscrew of the throttle shaft is lost, causing it to jam.
It is not difficult to solve all these problems; you need to conduct a careful inspection and accurately determine the cause, and then replace the faulty part. As a rule, if the chainsaw picks up speed well, idles and has normal power, then the problem with the fact that it does not slow down is purely mechanical. And finding and eliminating a mechanical fault is much easier than identifying and stopping air leaks in the chainsaw crankcase.

Conclusion
If the first signs of loss of power (reduction in speed) appear with the Shtil MS 180 chainsaw, under no circumstances should you continue to work, but you should immediately contact a specialist or carry out diagnostics and fix the malfunction yourself. There are not many reasons for power loss and you can cope with them even without certain skills. The main thing is to calmly analyze the behavior of the saw and find out the reasons why it stopped pulling (the speed dropped), and eliminating the malfunction is not a difficult task.
Reasons why Calm 180 does not develop speed
Chainsaw quiet 180 does not develop speed or after you release the throttle it continues to run without losing speed. These problems are quite common. Let's try to understand the reasons that result in the occurrence of such problems. Also in this article we will look at how to diagnose if your chainsaw is not snagging.

Why does the chainsaw not develop speed?
There may be several reasons for the lack of traction and poor speed of a chainsaw. Therefore, do not immediately start disassembling and repairing the carburetor, because the reason may be hidden and not in it.
The calm 180 chainsaw is equipped with a reliable carburetor, on which the manufacturer limits the ability to adjust power and maximum engine speed, so when the chainsaw falls, the carburetor is the last place to look for a problem.
Muffler
What's first, you ask? The answer is a muffler. The muffler is responsible for exhaust gases and suppressing flames in them. All combustion products pass through it, which can eventually clog it. A clogged muffler situation is not unusual, but is caused by an incorrect fuel mixture.
With a normal ratio of gasoline to oil, the combustion products are not saturated with soot sufficient to clog the muffler. If there is more oil than normal when it burns, excessive carbon deposits will form. Additionally, sludge builds up under the piston rings and in the Calm 180 chainsaw muffler. So, smoked muffler, the most harmless thing that can happen, the most damage from excessive carbon emissions, is the need to replace the piston.
How to check the muffler
To check the muffler, it must be removed from the chainsaw. To do this, using an 8 mm socket, unscrew the two nuts and remove the part.

Important: When tightening the muffler nuts, do not over-tighten the nuts as the threads on the screws may be stripped.
The second reason why the gasoline engine chain saw may reduce power and does not develop speed, is a blockage in the fuel system. Generally, the first place you should start looking for a clog is the fuel filter.
Check the fuel filter
The fuel filter is installed in the 180 gasoline chainsaw, and it is not very convenient to remove it. To make the process easier, you can take a small piece of aluminum wire and bend it at the end, then use it to tighten the fuel hose and pull it and the filter out of the tank. To check the filter in it, you need to blow it out; if air does not pass through, then the cause has been found and the filter must be replaced.

If the filter is clean, you need to check the fuel hose for blockages. To check, you need to disconnect it from the carburetor and blow an air filter into it. If a blockage is detected, the hose can be cleaned mechanically using a wire and then blown out with compressed air.
Strainer in carburetor
The last possible place for a blockage to form is the strainer in the carburetor. The diagram below shows the number 13.

To clean the strainer, you need to remove the carburetor from the Windshield 180 chainsaw. The job begins by removing the top cover of the saw, after which the two nuts are unscrewed using an 8mm socket. In addition, it is removed from the filter housing guides, after which the choke rod and the engine control lever are disconnected. Finally, the fuel hose and throttle body are disconnected and the carburetor can be removed from the guides.
The carburetor filter is installed in the fuel pump chamber; to achieve it, one screw securing the pump cover is loosened and removed along with the gaskets.
Clean the mesh filter, you can only use compressed air. Any mechanical methods are strictly prohibited because the mesh is very soft and easily changes shape. It creases easily when you push it, and there are curves on the edge of the seat that prevent filtered fuel from getting into the carburetor.
During the cleaning process, the seat with the filter installed in it should be half-closed with your finger, and then only blow air, otherwise the mesh may fly away and can no longer be found.
Carburetor depressurization and injector clogging
Sometimes, when the carburetor cover screws are loose or the gaskets are unusable, loss of power can also occur on the chainsaw, to rule out the possibility of this malfunction, it is necessary to check the integrity of the gaskets and tighten the screws on the carburetors. To do this, remove it from the engine (algorithm described above) and disassemble it. Defective gaskets must be replaced using spare parts from the SMI 180 carburetor repair kit.
In the case where a complete check of the fuel supply and exhaust system has been carried out, but there are no results. The main fuel injector valve needs to be checked. To check, you need to knock it out of the carburetor body. All work must be performed according to the following algorithm:
- The carburetor is removed from the chainsaw.
- Four screws are designed to secure the cover with the compensator, after which the cover can be removed.
- The carburetor is mounted on a wooden lining, then with a bolt with a diameter of no more than eight millimeters and a length of 50, it is knocked out into the internal cavity of the carburetor.
- Then you need to select a small hose whose internal diameter matches or is slightly smaller than outside diameter injector and place it on the nozzle.
- The next step is to hit the inside of the hose. If it only blows in one direction the nozzle is fine, if it blows in both or not at all the valve needs to be replaced.
All of the above steps should help in eliminating the problem that the chainsaw does not pick up speed, otherwise it will help to carry out a full diagnosis at the manufacturer’s service center.
Why doesn't a chainsaw lose steam?
There may be several reasons why a chain saw does not lose momentum:
- throttle spring broken;
- jamming of the throttle trigger;
- Throttle valve socket is bent;
- Lost the corkscrew of the throttle shaft, causing it to jam.
It is not difficult to solve all these problems; it is necessary to conduct a careful inspection and accurately determine the cause, and then change the defective part. Generally, if the chainsaw is revving, idling and has normal power, then the problem is that it is not slowing down, it is purely mechanical. And finding and fixing a mechanical fault is much easier than identifying and stopping the air intake in the chainsaw crankcase.

Why does the chainsaw stall when I press the gas: premises and solution
There are often cases when owners of chainsaws are faced with their breakdown and it does not matter at all what model of this type of equipment, because the nature of breakdowns is almost the same for everyone. Well, the chainsaw has stalled, so what next? Of course, you can take the equipment to special services that will repair your “iron friend” for a fee. Chainsaw Shtil 180 does not supply oil and supply oil to the chain?. But as they say: why pay more?
After all, you can personally disassemble the tool and repair it, because the damage may be insignificant, but in the service you will pay a lot for it. But naturally, in order to bring a tool back to life yourself, you need to be able to understand the reasons for its breakdown and methods for eliminating defects. On chainsaws Shtil ms 180 rpm cannot be adjusted. So let's educate ourselves! In this article you can find answers to questions regarding situations when the tool simply stalls after a specific press on the gas. So let's get started.
Basic elements of chainsaws
Before we begin to delve into the issues of tool breakdowns and repairs, let’s first understand what a chainsaw actually consists of. First, I would like to note that this tool belongs to the category of equipment whose operation directly depends on the gasoline engine.
It is also important that chainsaws are equipped with a single cylinder engine, and whose work is done on such fuel as gasoline. It should be noted that, despite the similarity with other tools, it does not have a gearbox. And it is replaced by a typical single-stage chain transmission, the means of which is the movement of the chain (saw) itself.

In fact, the chainsaw is quite conventional design, but this does not prevent it from being reliable, convenient and fully capable of ensuring specific uninterrupted and cyclic operation even in rather difficult conditions. On the chainsaw there is a calm, the chainsaw calm 180 does not start and the spark plug is flooded. The Stil MS 180 chainsaw does not require special care. Chainsaw Shtil 180 – malfunctions and. This tool consists of a huge range of certain parts “vital” for its correct and productive operation. This is a carburetor, a specific chain tension device, a tire equipped with a chain and other elements.
Before purchasing a chainsaw, be sure to explore all the options and choose the brand of chainsaw that is right for you.
To make your choice easier, we have compiled a rating of chainsaws based on reliability.
If you have a limited budget, then read the article about Russian chainsaw manufacturers.
Characteristics and possible causes of failure. Chainsaw Shtil 180 - does not develop speed - building materials and tools - technical forum. Fixing the problem yourself
Chainsaws are fairly reliable and lightweight designs. On chainsaws Shtil ms 180 rpm not on chainsaws Shtil carburetor adjustment. Therefore, if you properly care for them and handle them based on the manufacturer’s advice, then they fail very rarely and various types of breakdowns are quickly eliminated. But if you are faced with this situation and want to repair your own instrument yourself, without resorting to the help of experts, then delve into the information presented below.
In fact, it is impossible to clearly and accurately determine the reason why the tool does not start. or it stalls when you press the gas, because there are quite a few reasons that influence this. But we should not forget that, starting from the fact that the chainsaw is armed with a conventional two-stroke engine, such conditions as lubrication, fuel, spark and air are important for its effective performance.

As follows, it is the carburetor that produces the fuel-air mixture, the filter cleans the air from dust, the ignition unit and spark plug produce a spark, and the gasoline contains lubricant.
That is why it is necessary to search for the circumstances of this kind of breakdown in order, starting specifically from the easy ones and gradually moving on to the complex ones. Good evening, I have a problem with the Shtil 180 chainsaw that doesn’t pick up speed right away on gas. And this is a fundamental factor proper repair, because the person who, without thinking it through, begins to disassemble the carburetor, brings her to risk. Because that kind the unit must be repaired or adjusted directly in special workshops(read about carburetor adjustment).
- An important fact is that for trouble-free operation of the tool, it is necessary to be quite attentive to the fuel itself. Since if this kind of mixture is not prepared correctly, then most chainsaws simply will not start. Consequently, not every owner will think to look for the cause of the breakdown in the fuel. That is why, in order for your tool to always work correctly, you need to use only high-quality gasoline for the mixture.

Why does this kind of problem appear? saw worked great, but suddenly the power disappears and Not promotion
The saw does not develop speed, does not develop power.
Why Stihl 180 not starts up does not develop speed, Friends, if something needs to be explained in more detail, ask.
And also use only the oil that is made by the manufacturer of your tool. Chainsaw calm 180 - does not develop speed. Chainsaw Calm 180 - does not develop Chainsaw Calm 180 does not develop speed, stalls. In addition, it is important to prepare this kind of mixture in the amount that you will definitely use in one or two weeks, but no more (see the proportion of gasoline and chainsaw oil).
Because otherwise, overexposure of the mixture directly in the canister will lead to it losing all its octane properties and this will lead to significant problems with the instrument.
Spark plug inspection Do not forget that by examining the spark plug you can obtain significant information regarding the breakdown of the chainsaw. Since if its surface is dry, then the reason for this is the cylinder, into which fuel is not directly supplied. That is why you will have to check the entire range of its supply step by step. If the spark plug is covered in black soot, this means that the carburetor is not working properly, that is, it supplies either a lot of fuel or pours oil directly into gasoline.
Since, for example, a Stihl chainsaw stalls when you press the gas for a simple reason, namely a simple clogging of the direct breather.
In order to solve this kind of problem, all you have to do is disconnect the (fuel) hose from the carburetor and pay attention to whether fuel is leaking out of it. Since if the mixture flows in a full stream, this means that the breather is not contaminated, but if on the contrary, then the cause of the breakdown has been found.
Chainsaw piston But if after inspection you find that there is no damage on both the piston and the cylinder, then the reason may lie directly in the rings (piston). The Stihl chainsaw does not start 180 reasons and them For this type of check, you need to insert a piston into the cylinder and carefully begin to rock it using a connecting rod. If you suddenly feel play, then the rings need to be replaced, as they are already worn out.
First of all, what you should remember when purchasing this kind of tool is that certain parts of the saw need to be replaced with new ones after their service life (passport) has expired. It is for this reason that the instructions should always be at your fingertips, since everything is described there in detail.
These types of details include: sprocket (drive), tire, part of the system (anti-vibration), as well as a chain. Since we should not forget that if this “filling” is not replaced with a new one at the required time, then these worn-out spare parts will negatively affect the remaining parts of the chainsaw. It is for this reason that you should check the depth of the immediate tooth cutting quite often. Remember that it should not be higher than 0.5 mm a week.
To sum it up...
Definitely, every item we buy has its own expiration date and sooner or later it breaks, and it becomes a shame when the degree of its breakdown is so great that it cannot be repaired. But you must admit that quite often we are simply negligent in our technology, and when it stops working, then we try to find ways to fix the breakdowns, contacting great amount services.
But remember that even though the equipment breaks down, we can extend its “life”. All you need to do is simply take care of it and keep its parts clean and tidy. And then, undoubtedly, it will serve for many more years. It is also important to use exclusively high-quality spare parts and “additives” (see attachments for chainsaws). Then your equipment will work smoothly, and you will simply forget what repairs are. Chainsaw oil Hello everyone! In this article I will tell you which chainsaw oil to use. Who uses what oil to lubricate the chainsaw chain. The information presented here is based on both my personal experience using saws, and from the experience associated with the fact that I am a seller of this technique - this is also about ...
In the review, we will consider what faults and repairs that can be carried out independently can be identified in such a unit as the Shtil 180 chainsaw. It has proven itself well in the market for relevant products. This tool is popular among consumers. It is a portable device with a power of 1400 W. The chain length is 350 mm, the engine capacity is 31 cm 3. At idle, the equipment makes 2000 revolutions per minute or more.
The popularity of this unit is also due to reasonable price. But when using of this instrument Some problems may arise from time to time. After the warranty period expires, you can carry out repairs yourself, because the services of specialists service center are quite expensive.
The main malfunctions of the Shtil 180 chainsaw
The Shtil 180 chainsaw, the faults of which you can identify and repair yourself, must be operated in accordance with the manufacturer’s instructions. The start button, for example, should be turned on only after the technician checks the chain tension and also makes sure that the corresponding tanks are filled with oil and fuel mixture. The chainsaw must be securely fixed in your hands, only then can you begin work.
Violation of tightness
But if you notice that chain oil is leaking, then the cause of the malfunction may be a leak in the joints between the oil tank hose and the oil pump. In order to fix the problem, you will have to disassemble the tool. If the hose is damaged, it is recommended to replace it. Sometimes it is sealed special composition. The surface should first be degreased and washed. Sometimes the oil filter fails, in some cases it becomes clogged. In this case, oil may also leak. In this case, the filter is checked, cleaned or replaced with a new one.
Refusal to work
The Shtil 180 chainsaw, the faults of which you can identify and repair yourself, sometimes simply does not start. This problem can arise completely by accident. First of all, the consumer needs to open and close the gas tank cap again. Ventilation of the combustion chamber must be carried out in the next step.
It is recommended to remove the candles and dry them well. In some cases, this is enough for the tool to start and work properly. If the problem remains, then the reason is different. The breather affects the fuel supply. If it becomes clogged, a vacuum occurs in the fuel tank, which results in failure of operation. The breather can be repaired very simply. To do this, it is cleaned with a needle.
If you purchased a Shtil 180 chainsaw, you can find and repair this tool yourself. Sometimes equipment fails to work because the cylinder fails. If there are unevenness and chips on this unit, then this is definitely the reason. If you encounter a problem where the tool does not start, holds power for a short time, or stalls after turning on, then the muffler may be causing the problem. During operation, it sometimes becomes clogged with deposits that occur during exhaust.
The saw sometimes has difficulty starting, which is caused by starter malfunctions. In order to identify the problem, it is necessary to remove the cover and a special screen from the carburetor, which is located behind the tool drum. If the contact wire is disconnected from the starter, it is fixed with a blowtorch. Sometimes the problem is an oil leak. In this case, the starter must be wiped with a rag.
The engine runs intermittently
You can begin to identify malfunctions of the Shtil 180 chainsaw yourself if the warranty period has expired. Sometimes the engine runs intermittently, which can be caused by a failure of the cylinder piston group. You can repair it yourself. To remove the cylinder from the tank, it is necessary to unscrew the bolts on its head. The technician should check the piston; there should be no chips, scratches or burrs on it. If any can be found, then the piston must be replaced.
Piston rings and piston provide optimal pressure in the combustion chamber. The rings must fit tightly onto the piston body. If the piston inserted into the cylinder has free movement when rocking, then this indicates its wear. To fix the problem, it is necessary to bore the cylinder and install repair parts. But the easiest way would be to replace the CPG kit.
Carburetor malfunctions
If you purchased a Shtil 180 chainsaw, you can detect and carry out carburetor malfunctions and repairs yourself. If the tool stops starting, begins to stall and is unable to maintain power, and also does not hold idle speed, then the carburetor may be the cause of the breakdown. During operation, it quite often becomes clogged with dirt, dust or sawdust. The problem can be resolved by cleaning it.
Malfunctions of the carburetor of the Shtil 180 chainsaw can be resolved after preparing some tools, including:
- brush;
- head at 8;
- crosshead screwdriver;
- petrol.
A brush can be used to clean away dust and dirt. Then remove the cover and filter. The two nuts of the air filter are unscrewed, which will allow you to remove the air collector housing. You should now be able to see the carburetor. After lowering the throttle down, you need to remove the accelerator lever.
In order to move the carburetor, it is necessary to remove the choke lever and close it. Now you should remove the engine stop wire and pull it towards you. The plastic lever is removed and the wire is fixed to it. At this stage the carburetor can be released and removed for cleaning. It is best to use a compressor for this, but if one is not available, flushing can be done with pure gasoline.
When considering the main malfunctions of the Shtil 180 chainsaw, you should know that you should not forget about the fuel filter. It is removed and the fuel hose is blown out. Now you can put everything back together in reverse order. If, after assembling the carburetor, the tool still does not start well and the muffler produces smoke, then the spring under the needle lever has been lost. Due to its absence, the needle does not shut off the fuel supply. As a result, the spark plug is flooded with gasoline. To fix this problem, you need to find the spring and install it in place.
When repairing a carburetor, you must remember that it is a complex unit consisting of rings and many parts. This indicates that cleaning and repairs must be carried out with extreme care. If the tool stalls or does not start, then, in addition to the carburetor, it is necessary to check the spark plugs. If they are faulty, they are unscrewed and dried.
Excess fuel can be drained through a special hole. Malfunctions of the Shtil 180 chainsaw and their elimination are partially described in the instructions. After reading the article, you can understand that the candles should be dried for at least half an hour; after this time, the candle can be replaced in place by starting the unit.
Conclusion
Sometimes the cause of the malfunction is poor contact between the high-voltage wire and the end of the spark plug. If the craftsman does not like the work of the candle, it is replaced with a new one. Before repairing, you must remember that the tire, chain, and anti-vibration elements wear out much faster than other parts. Therefore, for smooth operation, it is necessary to keep the listed spare parts in your arsenal.
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 the operation of this tool as easy as possible. This chainsaw is lightweight and easy to use, and also has 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 the chainsaw has an internal combustion engine, 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 on the new spark plug, then the problem should be looked for 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. If the filter is heavily soiled, it is recommended to replace it 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 flow in 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, and also 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
In case on idle speed The engine runs fine, but when the speed increases, it stalls, 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 thoroughly clean the interior. 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.
