So, I have already said before about what should be checked in a chainsaw in order to know the cause of its malfunction. Today I’ll move to more valuable instructions so that you don’t look for the cause of the problem for a long time and know about how to solve it. Chainsaw is not the most difficult tool, but you need to properly care for it. There are different cases, sometimes the chainsaw stalls when you press the gas, sometimes in the load, and sometimes it does not work at all at idle. Let’s look at different situations together and try to find the right solution.
If you find that the tool does not start at all and stalls, then you do not need to rush immediately to the service center, you can try to solve the problem yourself.
Checking the main chainsaw systems.
We consistently check each system:
- Fuel tank. Perhaps there is not enough fuel or it is of poor quality.
- The following spark plugs and high-voltage wire fall under the test. Note that the clearance of the spark plug does not normally exceed half a millimeter.
- If the above items are checked and work correctly, go to the carburetor and fuel filter. With the breakdown of the carburetor need to contact the experts.
Stalls on the “idle”?
Sometimes the saw stalls at idle, and clogging the silencer is a common cause of breakage. It can be easily cleaned by yourself, it does not need a high specialist.
In addition to cleaning there is another option, but we treat it very carefully so as not to harm the internal parts of the device.
To adjust the carburetor, you need to find two bolts with the letters L and H. The last one needs to be turned, a little bit, only half a turn. He is responsible for the revolutions of the tool and, if necessary, raise the idling speed.
Turns off when loaded?
Often powerful chainsaws stall from the load. Most likely you have a fuel filter clogged, and it needs to be replaced. If this does not help, then you need to check the quality of the fuel mixture and prepare a new one.
Saw stops working at higher revs?
Filters are often clogged, especially when the chainsaw is running almost daily. The air filter can be disconnected and washed under running warm water. Before you put in place. dry thoroughly.
If after disconnecting the fuel hose from the carburetor fluid does not flow out of it, it means that it is clogged. It can be cleaned, or replaced with a new one.
With frequent use of the tool, a gasoline pump can fail. After all, every detail has its own shelf life. It should be replaced or contact the service center.
Saw turns off when turning?
In a horizontal position, the fuel tube is at the bottom of the tank, but if the tool is tilted, the fuel will not be able to completely cover it. This is what causes the chainsaw to stop working when tilting, as the tube levitates in the air and does not receive the right amount of the mixture.
Problems “on hot”?
If you notice that the chainsaw starts without any problems without warming up, and after warming up it stalls. And do not start it until it cools, here, perhaps a few problems.
First, perhaps somewhere there is a suction hose, stuffing box or gasket. Secondly, inspect the silencer for the presence of soot. The third reason is the cylinder-piston group (CPG), whether there are no scuffs or irregularities.
Sometimes a carburetor setting is required. Another important cause of a malfunction is the ignition coil. In cases when it fails, the spark is lost or becomes very weak, which is not enough to ignite the fuel mixture.
There are cases when the master tries hard, the engine, then on the cold, then on the hot, thereby pumping fuel. Here you need to pull yourself together, transfer the damper to the “hot start” and gradually start the tool. At the same time bring down the speed to almost idle level and 40-45 seconds it warms up.
Saw stalls after releasing the “gas”?
Here you need to adjust the carburetor and check whether there is a powerful air suction.
We have already made out the most common cases of breaks in the chainsaw. It remains only to fill your saw that will serve without damage. But even strong models like Stihl and Partner can sometimes fail.
Do not rush to immediately run to the service center, first use my advice, so you can avoid large cash costs.
