The calm does not develop the speed of the chainsaw

Because of what the Stihl chainsaw does not develop speed and stalls

If the chainsaw does not develop speed, then first of all it is recommended to check the fuel system. This is the first place to start, since the chainsaw engine simply does not have enough fuel mixture in order to operate at full power.

calm, does, develop, speed, chainsaw

The slightest blockage in the fuel filter can lead to a lack of fuel entering the carburetor. It is very easy to get to the fuel filter, it is located in the saw’s gas tank.

When checking, you need to disconnect the hose from the filter, then blow into the filter tube. If the filter does not allow air to pass through, or it does not pass well, then it is recommended to replace it. A new fuel filter is not so expensive, about 100-150 rubles.

The second reason due to which the Stihl chainsaw may not develop speed is a large carbon deposit in the muffler. An abundant amount of combustion products is formed as a result of incorrect proportions of oil and gasoline. As a result, the hole in the muffler is heavily coked, which leads to a drop in the power of the chainsaw.

Most experts immediately begin to sin on the carburetor. The chainsaw is disassembled and cleaned. However, this does not always help, since sufficiently reliable and durable carburetors are installed in the Stihl chainsaws. Therefore, cleaning them should be resorted to as a last resort.

What to do if the Stihl chainsaw does not develop speed? Where to start looking for a problem? Read in this article the construction magazine samastroyka.ru.

How to clean a chainsaw muffler

It is quite easy to remove the muffler from the Stihl chainsaw. To do this, unscrew the two nuts fixing it, and then dismantle it. It is possible that after removing the muffler, it will be necessary to change the gaskets that are located between it and the cylinder.

It is best to use compressed air to clean the muffler. If carbon deposits are strongly adhered to the surface, then you cannot do without a mechanical method, using something suitable for these purposes. Perhaps it is after cleaning the muffler that the chainsaw will work as before.

If this did not help, then there is one more “problematic place” in the Stihl chainsaws. this is the carburetor mesh filter. Therefore, if replacing the fuel filter, cleaning the hose and muffler, did not give results, then you must definitely check if there is a blockage in the mesh filter of the chainsaw carburetor.

To get to the mesh filter, you will have to remove the carburetor, it is behind it that the fuel pump chamber is located. Often this work requires caution and care, so if you are unsure of your actions, then it is better to entrust the repair of the Shtil chainsaw to an experienced specialist.

Why the chainsaw doesn’t slow down

There can be several reasons why the chainsaw does not slow down:

  • broken throttle spring;
  • jamming the gas trigger;
  • the throttle rod is bent;
  • lost throttle shaft corkscrew, causing it to wedge.

It is not difficult to solve all these problems, you need to conduct a careful inspection and determine the exact cause, and then change 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 malfunction is much easier than identifying and stopping air leakage in the crankcase of a chainsaw.

Why the chainsaw does not develop momentum

There may be several reasons for the lack of traction and poor set of revolutions with a chainsaw. Therefore, you should not immediately begin to disassemble and repair the carburetor, since the reason may be hidden and not in it.

The chainsaw has a calm ms 180, a reliable carburetor is installed, on which the manufacturer limited the ability to adjust the power and maximum engine speed, therefore, when the traction falls at the chainsaw, the carburetor is the last place where you need to look for problems.

Muffler

You ask, what is the first? The answer is a muffler. The muffler is responsible for exhausting the exhaust gases and extinguishing the flame in them. All combustion products pass through it, which over time can clog it. The situation with a muffler clogged with soot is far from uncommon, but it occurs due to the wrong fuel mixture.

With a normal ratio of gasoline to oil, the combustion products are not saturated with soot enough to clog the muffler. In the event that the amount of oil is more than the norm, excessive carbon deposits are formed during its combustion. Further, carbon deposits accumulate under the piston rings and in the silencer 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.

The reasons why Calm 180 does not develop momentum

Chainsaw calm 180 does not develop revs or after you release the gas trigger, it continues to work without dropping the revs. These problems are quite common. Let’s try to understand the reasons, the consequence of which is the occurrence of such malfunctions. Also in this article we will consider how to diagnose if the chainsaw does not pull.

Checking the fuel filter

The fuel filter is installed in the tank of the Stihl 180 chainsaw, and it is not very convenient to pull it out. To facilitate the process, 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, it is necessary to blow into it, if air does not pass, then the reason has been found, and the filter must be replaced.

If the filter is clean, check the fuel hose for clogging. To check, it is necessary to disconnect it from the carburetor and, with the air filter removed, blow into it. If a blockage is found, the hose can be cleaned mechanically, using a wire, and then blown out with compressed air.

How to check the muffler

To check the muffler, it must be removed from the chainsaw. To do this, using an 8 mm head, two fastening nuts are unscrewed and the part is removed.

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 muffler seat can be cleaned with emery paper to remove burnt-on gasket parts.

Install the muffler in reverse order.

Important: when tightening the nuts of the muffler, do not pull the nuts excessively, since the threads on the screws can be torn off.

The second reason why the engine of a chainsaw is calm can reduce power and not develop speed is a blockage in the fuel system. As a rule, the first place where you need to start looking for a blockage is the fuel filter.

Depressurization of the carburetor and blockage of the nozzle

Sometimes, when the screws securing the carburetor cover are loosened or the gaskets have become unusable, there may also be a loss of power on the chainsaw, in order to eliminate the likelihood of this malfunction, it is necessary to check the integrity of the gaskets and the tightening 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. Defective gaskets must be replaced using spare ones from the repair kit for the Shtil MC 180 carburetor.

In the case when 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, it is necessary to knock it out of the carburetor body. All work should take place according to the following algorithm:

  • The carburetor is removed from the chainsaw.
  • The four screws securing the cover with the compensator are loosened, after which the cover can be removed.
  • The carburetor is installed on a wooden lining, after which it is knocked out into the internal cavity of the carburetor using a bolt with a diameter of no more than eight millimeters and a length of 50.
  • Next, you need to pick up a small hose, the inner diameter of which corresponds to or slightly less than the outer diameter of the nozzle and put it on the nozzle.
  • The next step is to blow inside the hose. If it is blown only in one direction, the nozzle is in good working order, if it blows in both directions or does not blow at all, then the valve must be replaced.

All of the above actions should help in eliminating the malfunction associated with the fact that the chainsaw is not gaining momentum, otherwise, a full diagnosis at the manufacturer’s service center will help.

Mesh filter in the carburetor

The last likely place for clogging is the filter in the carburetor. In the diagram below, it is indicated by the number 13.

In order to clean the mesh filter, it is necessary to remove the carburetor from the Stihl 180 chainsaw. Work begins with the removal of the upper saw cover, after which, using an 8 mm head, two fastening nuts are unscrewed. Further, the filter housing is removed from the guides, after which the air damper rod and the engine control lever are disconnected. Last of all, the fuel hose and throttle rod are disconnected, after which the carburetor can be removed from the rails.

The carburetor mesh filter is installed in the fuel pump chamber, in order to get to it, one screw securing the pump cover is unscrewed and it, together with the gaskets, is removed.

The strainer can only be cleaned with compressed air. Any mechanical methods are strictly prohibited, since the mesh is very soft and easily changes shape. When you press it, it is easily crumpled and bends are formed along the edge of the seat, through which unfiltered fuel can enter the carburetor.

In the process of cleaning, the seat with the filter installed in it must be half-covered with a finger and only after that blow with air, otherwise, the mesh may fly away and it will no longer be possible to find it.

Why does the chainsaw immediately stall and jam when the gas is pressed

Saw repair after 10 tanks. What sellers are silent about.

The Stihl MS 180 chainsaw has some nuances that make owners nervous and is wasted on expensive.

Chainsaws are fairly reliable and uncomplicated designs. Therefore, if you properly care for them and handle them based on the manufacturer’s recommendations, then they fail well, very rarely and various kinds of breakdowns are quickly eliminated. But if you are faced with this situation and want to personally repair your tool without resorting to the help of professionals, then delve into the information provided below.

In fact, it is unambiguously and precisely impossible to determine the reason why the tool does not start or stalls when you press the gas, since there are a lot of factors affecting this. But do not forget that, starting from the fact that the chainsaw is equipped with a simple two-stroke engine, conditions such as lubrication, fuel, spark and air are important for its effective performance.

Chainsaw fuel tank

Consequently, the carburetor is directly involved in the preparation of the fuel-air mixture, the filter cleans the air from dust, the ignition unit and the spark plug create a spark, and there is lubricant in the gasoline.

That is why it is necessary to search for the causes of this kind of breakdown in a sequential order, starting directly from the simple ones and gradually moving on to the complex ones. And this is an important factor in the correct repair, since the person who, without thinking, begins to disassemble the carburetor, brings it to risk. Since this kind of unit must be repaired or adjusted directly in special workshops (read about adjusting the carburetor).

An important fact is that for the trouble-free operation of the tool, it is necessary to be careful enough directly to the fuel. Since if this kind of mixture is not prepared correctly, then most chainsaws will simply not start. Consequently, not every owner will guess 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 exclusively high-quality gasoline for the mixture.

Otherwise, overexposing the mixture directly in the canister will lead to the fact that it will lose all its octane properties and this will lead to significant problems with the instrument.

Also, the cause of a breakdown can be the direct filling of the mixture with a candle at the moment when the mechanism is started. In order to solve this problem, it is necessary to unscrew and dry the candle, but remember that it should never be ignited. Excess fuel must be drained through the hole (plug), wait 20-30 minutes, then put it back in place and try to start the tool again.

The chainsaw stalls when you press the gas due to the fact that there is no spark. This can happen when there is no good contact between the tip of the candle and the wire (high voltage). However, if this kind of connection works correctly, but there is still no spark, then the whole reason is the ignition unit (electronic). It is important to note that these types of parts cannot be repaired, so they can only be replaced.

Do not forget that by examining the spark plug, you can get significant information regarding the breakdown of the chainsaw. Since if its surface is dry, then the reason for this is the cylinder, which is not directly supplied with fuel. That is why you will have to check the entire range of its presentation step by step.

If the chainsaw stalls when gas is added, it means that the fuel is not supplied in sufficient quantities for the full operation of the chainsaw. This may be due to both clogging of the carburetor (its jet) and contamination of the filter itself (fuel). Remember that only professionals should check the first node, but you can clean the second one yourself.

Additional Tips

First of all, what you should remember when purchasing this kind of tool is that certain parts of the saw must be replaced with new ones after their service life (passport) has expired. It is for this reason that the instruction should always be at your fingertips, since everything is described in a detailed way there.

Parts of this kind include: an asterisk (leading), a bus, a part of a system (anti-vibration), and a chain. Since you should not forget that if this “filling” is not changed to a new one at the right time, then these worn-out parts will negatively affect the rest of the chainsaw. It is for this reason that you frequently check the depth of the direct toothing. Remember that it should not be higher than a week 0.5 mm.

The main elements of chainsaws

Before starting to delve into the issues of breakdowns and tool repairs, let’s first figure out what the chainsaw itself consists of. First of all, I would like to note that this tool belongs to the category of equipment, the operation of which directly depends directly on the internal combustion engine.

Single cylinder engine

It is also important that chainsaws are equipped with an engine with one cylinder, and the work of which is carried out on such kind of fuel as gasoline. It is worth noting that, despite the similarity with other tools, it does not have a gearbox. And it is replaced by a kind of single-stage chain transmission, through which the movement of the chain itself (saw) is made.

In fact, a chainsaw is a fairly simple design, but this does not prevent it from being reliable, practical and fully capable of providing direct uninterrupted and cyclical operation even in rather difficult conditions. This tool consists of a huge range of certain elements “vital” for its correct and productive work. This is a carburetor, a direct chain tensioner, a tire complete with a chain and other elements.

Before we get into the breakdown and repair tool issues, let’s first figure out where the chain came from. First of all, I would like to note that this tool belongs to the category of equipment, the operation of which directly depends directly on.

It is also important that Chainsaws are equipped with a single cylinder engine
, and whose work is done on a fuel such as gasoline. It is worth noting that, despite the similarities to other tools, it does not have a gearbox. And it is replaced by a kind of single-stage chain transmission, through which the movement of the chain itself (saw) is made.

When you hit the gas

Sawing units are idling, but the saw stalls when the gas is pressed, as the load increases. Before use, the tool is warmed up by running the engine at idle for a minute. If this is neglected, the motor will stop after the pedal is depressed. Other reasons could be:

  • clogged or unregulated combustible fuel mixing unit;
  • a clogged air filter does not provide the required air flow when the load increases;
  • a dirty gasoline filter does not pass the required amount of the mixture;
  • rubs the wall of the cylinder and piston.

Low octane number of fuel causes brakes, since this circumstance does not allow the engine to reach the required power when the load increases.

Violation of the functionality of the fuel unit system leads to air leakage. In this case, the unit stalls at idle and does not keep their number. Additional suction reduces the air impulse to the fuel pump and passes through the sump membrane or crankshaft oil seals. Diagnostics is done with a vacuum gauge.

The termination of engine cold operation occurs for other reasons:

  • the candle channel contains an excess amount of the combustible mixture;
  • the gap between the tip of the candle and the high-voltage cradle is not adjusted;
  • power supply failure.

The oil seals are checked by pouring gasoline into the crankcase, the leak is visible visually. This means that the engine does not idle, and at a high frequency, leaking oil seals will lead to seizure of the bearings. In case of leakage of elements, they are replaced with new ones and they are sealed.

Filter dirty

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 the fuel is leaking from 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.

Mod Review – Easy Development Controls

Here’s another reason why the chainsaw stalls when you press the gas. the muffler. It is this part that can interfere with the full operation of the tool in cases where it is contaminated directly with exhaust resinous deposits. To do this, you just need to clean it.

Quite often, the partner’s chainsaw stalls when pressed and the reason for this is the cylinder-piston group. Since by examining them, namely the piston and cylinder, you can easily determine the cause of the malfunction of the tool, by directly replacing them. You can also make a direct boring of the cylinder itself relative to the size of the new 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). For this kind of check, it is necessary to insert a piston into the cylinder and gently start wiggling it by means of a connecting rod. If suddenly you feel a play, then the rings need to be replaced, since they have already worn out.

Many people ask the question: why does the chainsaw stall when I press the gas? The answer may also lie in insufficient chain lubrication (see oil for the chainsaw chain), since the oil line may leak, or the direct channels may simply be clogged. That is why pay attention to the chain, because if it is dry, then, without delay, start to clean the channels that supply oil directly to the tool tire.

If the tool turns off immediately after starting, it means that a breakdown of some device or part has occurred. To determine the cause, the mechanism is tested independently or in service workshops. Sometimes the reason that the mechanism does not start well is due to improper saw maintenance:

  • insufficient amount of gasoline;
  • poorly prepared fuel mixture;
  • poor quality lubrication;
  • muffler clogged with combustion products;
  • unregulated carburetor;
  • obstruction of the air filter;
  • malfunction of the piston or cylinder.

At full speed

Sometimes the engine will stall after normal operation. To establish the cause, pay attention to the accompanying circumstances:

  • Motor stalls in the middle of operation for no apparent reason. The starter is stationary and does not turn. It means that the tool is jammed and requires urgent repair.
  • During normal operation, the power is reduced in a short time and the engine stops, the cylinders are overheated. The situation indicates the occurrence of air suction under the rubber pipe between the carburetor cylinder, possibly due to a rupture. Air depletes fuel, nozzle replacement required.

Why stalls at idle

Chainsaw calm 180 stalls at idle.

Chainsaw calm 180 does not gain momentum stalls.

The second way to check the performance of the oil seals is to pour gasoline into the engine crankcase and look at them, if the oil seals pass gasoline, it means they cannot provide normal pressure in the crankcase, which will make idle work impossible. And when operating at high speeds, with leaking oil seals, there is a possibility of seizure of the crankshaft bearings.

The algorithm for checking the Stihl 180 crankcase and oil seals for leaks is as follows:

  • The top cover is removed.
  • Dismantle the air filter housing and carburetor.
  • The handle of the chainsaw is removed.
  • The starter spins and retracts.
  • On the side opposite to the starter, the side cover and the drive sprocket are removed.
  • A piston stopper is installed in the spark plug hole or a string from an old starter with knots imposed on it is stuffed into the cylinder.
  • The flywheel and clutch are unscrewed, after which the parts are removed. It is worth knowing that the chainsaw clutch has a left-hand thread and unscrews clockwise.
  • The gear wheel of the drive of the oil pump is removed.

Having disassembled the Stihl MS 180 chainsaw, you can see the oil seals, then you need to fill the crankcase with gasoline and check the leakage. It is possible to fill the crankcase through the fuel window in the cylinder; for this, the piston must be raised as high as possible. If leaks are found, it is necessary to replace the defective oil seals, or re-seal the pallet. You can collect Calm 180 following the reverse sequence of the algorithm.

How to check the muffler

To check the muffler, it must be removed from the chainsaw. To do this, using an 8 mm head, two fastening nuts are unscrewed and the part is removed.

Install the muffler in reverse order.

Important: when tightening the nuts of the muffler, do not pull the nuts excessively, since the threads on the screws can be torn off.

The second reason why the engine of a chainsaw is calm can reduce power and not develop speed is a blockage in the fuel system. As a rule, the first place where you need to start looking for a blockage is the fuel filter.

Summing up.

Definitely, every thing we buy has its own expiration date and sooner or later it breaks down and how 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 careless about the technique (see about correct operation and how to properly cut down a tree so that it falls in the right direction). and when it stops working, then we try to find ways to eliminate breakdowns, while turning to a huge number of services.

But remember that even though technology breaks down, we can extend its “life”. All that is needed is to simply take care of it, do a break-in after replacing parts (read how the chainsaws are run-in, read here) and keep its parts clean and tidy. And then, undoubtedly, it will serve for many more years. It is also important to use only high quality spare parts and “additives” (see attachments for chainsaws). Then your equipment will work smoothly, and you will simply forget what repair is.

For what reasons Calm 180 stalls at idle or full throttle

Any tool can break and the Stihl MS 180 chainsaw is no exception. Today we will try to understand such issues as: why the chainsaw stalls when the speed increases, also at idle and at full speed. Consider the options for diagnosing and eliminating malfunctions associated with this behavior of the Stihl 180 chainsaw.

Why the chainsaw doesn’t slow down

There can be several reasons why the chainsaw does not slow down:

  • broken throttle spring;
  • jamming the gas trigger;
  • the throttle rod is bent;
  • lost throttle shaft corkscrew, causing it to wedge.

It is not difficult to solve all these problems, you need to conduct a careful inspection and determine the exact cause, and then change the faulty part.

Not enough fuel to feed and run the chainsaw at full power

If the chainsaw stalls when gas is added, it means that the fuel is not supplied in sufficient quantities for the full operation of the chainsaw. This may be due to both clogging of the carburetor (its jet) and contamination of the filter itself (fuel). Remember that only professionals should check the first node, but you can clean the second one yourself.

FASTEST CHAINSAW in the EAST! – Simple Trick – ANYONE CAN DO IT!

Wrong fuel

An important fact is that for the trouble-free operation of the tool, it is necessary to be careful enough directly to the fuel. Since if this kind of mixture is not prepared correctly, then most chainsaws will simply not start. Consequently, not every owner will guess 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 exclusively high-quality gasoline for the mixture.

And also use only the oil that is made by the manufacturer of your tool. In addition, it is important to prepare this kind of mixture in the amount that you definitely use in one or two weeks, but not more (see the proportion of gasoline and oil for a chainsaw).

Otherwise, overexposing the mixture directly in the canister will lead to the fact that it will lose all its octane properties and this will lead to significant problems with the instrument.
