Stihl 180 Does Not Reset Turnovers

Stihl 180 chainsaw not develops momentum as it is called, if you released the trigger of gas, it continues to work without losing momentum. These difficulties are quite widespread. Let’s try to understand the reasons, the result of which is the appearance of similar defects. Here we will also examine how to diagnose if the chainsaw does not pull.

Why is a chainsaw not develops momentum

The circumstances of the lack of traction and the disgusting set of revolutions of the chainsaw, you will like a few. Do not immediately start to disassemble and repair the carburetor, because the reason is hidden and not even in a personal computer.

On the Stihl ms 180 chainsaw, a reliable carburetor is installed, where the manufacturer limited the possibility of adjusting the power and the maximum engine speed, therefore, if the chainsaw falls in traction, the carburetor is the last place where you need to find problems.

Muffler

The question arises, but what is the first? The answer is a silencer. The silencer is responsible for exhaust emissions and the extinguishing of their flame. Through it pass to our client remains combustion products, which over time there are variations to hammer it. The situation with a soot jammed with soot is far from unique, but it appears because of the incorrect fuel consistency.

In the usual ratio of gasoline to oil, the combustion products are not saturated with soot so as to clog the muffler. In this case, if the amount of oil is not just the norm, when it burns, excess carbon deposits appear. Further, soot accumulates under the piston rings and in the muffler of the Stihl 180 chainsaw. Thus, a coked muffler is the safest thing that sometimes happens, the most harm from excess soot is the need to replace the piston.

How to check a muffler

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

Fundamentally: when the muffler is removed, it is necessary to check the integrity of the gaskets between it and the cylinder, because often they stick and break during the removal of the muffler.

Of course, clean the part mechanically, using a screwdriver or a spoke, and subsequently blow it well with compressed air. The seat on the muffler can be cleaned with sandpaper to remove burnt parts of the gasket.

Install the silencer in the reverse order.

Fundamentally: when tightening the nuts of the silencer mounting, it is not necessary to extremely tighten the nuts, since the threads on the screws can be ripped off.

Another reason why Stihl chainsaw engine can reduce the power does not develop speed, this is a blockage in the fuel system. Usually, the first place you need to start looking for blockages is the fuel filter.

Why the trimmer does not develop well.

Fuel filter check

The fuel filter is installed in the tank. Stihl chainsaws 180, and it is not too comfortable to pull out. To facilitate the process, of course, take a small piece of duralumin wire and bend it at the end, then use it to hook the fuel hose and pull it out, together with the filter from the tank. To check the filter, you need to blow in there, if air does not pass, it means the reason is found, and the filter needs to be changed.

Trimmer not gaining momentum, what to do?

Trimmer not gaining revolutions, very frequent problem is clear not always has the usual solution. In this.

If the filter is spotless, check the fuel hose for obstruction. To check, you need to disconnect it from the carburetor and blow it with the air filter removed. If clogging is detected, the hose can be cleaned mechanically using a wire, and then blown with compressed air.

Carburetor strainer

The last possible blockage is the strainer in the carburetor. In the diagram below, it is indicated by the number 13.

If you set a goal to clean the strainer, you need to remove the carburetor from Stihl chainsaws 180. Work begins with the removal of all additional parts that removes the top cover of the saw, then, using the 8 mm head, two fastening nuts are loosened. Further, the filter housing is removed from the guides, then the air damper rod and the engine control lever are disconnected. At the end of the process, the fuel hose and throttle rod are disconnected, after which there is an option to remove the carburetor from the guides.

The carburetor strainer is installed in the fuel pump chamber, if you set a goal to get to it, one screw securing the pump cover is loosened and it, together with the gaskets, is removed.

The strainer can only be cleaned with high pressure air. Any mechanical methods are strictly forbidden, because the mesh is very soft and just changes shape. When you click on its surface, it simply wrinkles and bends are formed along the edge of the landing site, through which unfiltered fuel can enter the carburetor.

During cleaning, the landing site with the filter installed there, you need to half cover with your finger and only subsequently blow air, otherwise, the mesh can fly away and it is already impossible to find it.

Carburetor depressurization and nozzle blockage

When, when the screws of the carburetor cover are loosened, in other words, the gaskets become unusable, a loss of power can also be observed on the chainsaw, to exclude 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. For this purpose, it is necessary to remove it from the motor (the method is described above) and disassemble. Defective gaskets need to be changed, using for this purpose you spare from the repair kit for the carburetor Stihl МС 180.

If there is a passage, when a full check of the accounting system for supplying fuel and exhaust gas has been carried out, but there are no results. Check the main fuel injector valve. To check, you need to knock it out of the carburetor body. All work should be done according to the following method:

  1. The carburetor is removed from the chainsaw.
  2. The four screws securing the cover with the compensator are loosened, after completion, of course, remove the cover.
  3. The carburetor is mounted on a wooden lining, then using a bolt with a diameter of less than eight mm and a length of 50, it is knocked out into the internal cavity of the carburetor.
  4. Next, you need to pick up a small hose, the inner diameter of which corresponds to what else it is called a little smaller than the outer diameter of the nozzle and put it on the nozzle.
  5. Next, it is necessary to blow into the hose. If it is blown exclusively in one direction, the nozzle is serviceable, if in both or generally it is not blown, then the valve must be changed.

What remains to do to our client the above acts are made to help to eliminate the malfunction associated with the reason that the chainsaw does not develop, otherwise, a working diagnostic option in the manufacturer’s service will help.

Why chainsaw does not slow down

The circumstances in which the chainsaw does not lose momentum you will like a few:

  • The throttle spring is broken;
  • Wedging gas trigger;
  • Throttle rod is bent;
  • The throttle shaft corkscrew is lost, and as a result it wedges.

It is not difficult to solve such difficulties, it is necessary to conduct a thorough inspection and establish the exact cause, then change the defective part. Usually, if a chainsaw develops well, runs at idle and has normal power, then the problem is that it does not slow down, it is purely mechanical. And to find and remove a mechanical malfunction is easier than to find and finish the air intake in the crankcase of the chainsaw.

Stihl 180 not develops rpm, of the most common premise, look below. There, the owner of the Stihl ms 180 chainsaw, knows his story of solving power loss hurdles.

Conclusion

If the first signs of loss of power (lower revolutions) occur with a Stihl MC 180 chainsaw, it is not necessary to continue working, but you need to immediately contact specialists or conduct diagnostics and fix the malfunction without the help of others. The circumstances of the loss of power are not so much to control having it of course even without certain abilities. The main thing is to quietly analyze the behavior of the saw and find out the reasons why it did not pull (the momentum has fallen), and removing the malfunction is already a simple matter.

All about gasoline saw revolutions

Modernization is in constant development. And the old chainsaws, which today, that could only saw wood, making a terrible roar and vibration, heard almost for kilometers, have long been in the past. In fact, noiseless, thorough tools to hold in the palm of your hands, which have now become a complete pleasure, have flooded the market, giving users a sense of complete happiness and technical freedom.

However, to the utter chagrin, no matter how advanced the technical equipment was visually and technically clear, its breakdowns are a fairly common occurrence, which domestic manufacturers say only by default. Chainsaws, functional working units, which require a lot of attention for users not familiar to themselves, are just an exception in order to rightly recognize the “catch” and stop the problem at the earliest stages.

The main of these aspects usually relate to the moment of launch, which should be taken with all responsibility. It is necessary to consider the main processes which can occur with a chainsaw when the motor is turned on.

Chainsaw not gaining momentum. How to be?

At the same time, this phenomenon is also coupled with the fact that the engine sometimes does not start at all, loses speed, and the load does not withstand a huge load than idling. If this problem is not worth mentioning, there is an option in general to “lose” it due to severe overheating.

The main reason for this usually lies in the field of motor, because there it is worth taking a closer look at the details.

Other points that could lead to such consequences are:

  • Malfunctions from spark plugs;
  • Tasks with a carburetor or simply incorrect adjustment.

The spark plug can be visually diagnosed if it is very dry or very humid on the contrary, and also with a significant coating on top. If you do not need to change it to the newest one, then simply clean it or dry it and test it in work outside the set of accounting programs for ignition of the saw.

In relation to the carburetor, the source of malfunctions can be:

  • Piston component wear;
  • Littering it;
  • Air filter breakdown;
  • Low octane gasoline and inappropriate properties;
  • Damage due to vibration of the tool itself.

In the base of each individual model usually lies 3-screw adjustment method, and screw “H” will help to reach the maximum torque.

Saw not develops momentum, does not develop power.

Why is there such a problem that it seems saw worked fine, but suddenly power is lost and not promotion.

Chainsaw does not develop momentum!

I sharpened the rubber process on al. A bit a bit a bit, collected and it worked. The second part not filmed.

And yet, if the chainsaw is not develops momentum, there may even be a reason not here, in the season in which the work is carried out. So, the minus marks of the temperature indicator is one of the reasons which can completely “knock down” the chainsaw. Some users note that in severe frosts, even pouring heated oil does not help and the lubricant involuntarily freezes on the tire. The ice coating of the carburetor and hoarfrost is also a fairly common thing. What of course to do?

To reduce tool operation before the onset of the body, or if the construct allows, change the damper mode from summer to winter, which is installed on separate models under the air filter cover.

What can serve as chainsaw does not keep idle?

As they say, start up. Start up, and then stalls and does not have time to go to the next power level. Many conditions can serve this:

  • Clogging of filtration parts;
  • Disturbances in the operation of the incendiary system;
  • Lost carb adjustments;
  • Gasoline drive is defective or damaged during operation;
  • Clogged muffler or exhaust ducts;
  • Malfunction of piston and installed valves.

Of course, it is difficult to conduct an independent diagnosis of everything at once, but moving around the proposed points you can still get an answer to your question. In half the cases, it’s enough to clean the carburetor, check the installation of the jets. And it’s done, chainsaw works as before.

What to do if the chainsaw does not take off speed?

The opposite of the previous situation is when the gas tool very quickly reaches high power and does not slow it down. At the same time, it can be observed that this cannot be eliminated in any way either by a screw on the case or by cleaning the carburetor. It would seem that what else is needed, the saw works, gives out power as in the instructions. But the trouble is that in this case, fuel is needed ten times more than usual.

The following actions can help:

  • Gas cable check;
  • Inspection of the return spring, which could simply slip;
  • Sealing the rear flap, which should be very tightly closed.

Usually one of these events can make a lot of sense.

Another technical problem is when chainsaw herself gaining momentum, the reason for which is usually not one. In this case, as well as under load, the saw may begin to stall occasionally, preventing it from being fully used for its intended purpose.

Leading reasons for this may be:

  • Clogged carburetor or fuel and air filter;
  • Violation of the integrity of the hose that delivers fuel;
  • Depressurization of the lead pipe from the carburetor to the engine cylinder;
  • And again the wrong setting of one of the screws (usually an H-screw) of the carburetor system.

Therefore, the simplest thing that can be to do At home, it is to clean the carburetor and filters, both air and fuel. It is important at the same time to maintain the correct adjustment of the screw elements L and H. Some advise to completely remove the fuel filter from the structure, but this is not an option, because the carburetor will not last so long.

Therefore, before starting work, you just need to look to see if it sinks in, if there are any kinks in the hoses along which the fuel flows, and then it will already be taken for more cardinal actions.

Stihl 180 Does Not Reset Turnovers

As you can see, there are many problems, but an excellent panacea for each of them is timely diagnostics that can answer many questions about the technical malfunction of the device even before they appear.

During operation of the chainsaw, various malfunctions can occur. In some cases, the owner has the opportunity to make repairs on his own, for example, when the speed drops. In this case, there are several reasons, and many of them are eliminated quite simply.

Causes

The drop in speed can be caused by the following reasons:

  • Faulty spark plug;
  • Carbon deposits formed on the spark plug;
  • The tightness of the carburetor is broken (“sucks” air);
  • Pollution in the fuel or air filter;
  • Wrong proportions of fuel and oil;
  • Low quality or low octane fuel;
  • Faulty coil (ignition module);
  • Piston rings worn.

All these problems can be fixed independently without the help of specialists.

What to do

First you need to disassemble the saw and carefully inspect the main details. Further, depending on the malfunction, you can perform the following actions:

  • Clean or replace the spark plug;
  • Change the clearance of the spark plug;
  • Replace the piston rings;
  • Try to adjust the air and fuel to the carburetor;
  • Replace gasket in carburetor;
  • Clean the fuel and air filters;
  • Pour other fuel;
  • Inspect fuel hoses for leaks.

If the saw stalls at start, then most likely the causes are contamination of the carburetor or filters, under loads. The cause must be sought in the fuel supply or the tightness of the gasket and fuel hoses.

Malfunctions in the work of a chainsaw arise often. It is important to take care of the instrument, use only high-quality fuel and regularly carry out diagnostics. Many problems can be fixed independently if you understand the device of the chainsaw. If this does not work, it is best to seek the help of qualified specialists.
