What should I do if the chain saw cannot start and is broken?

Gasoline chain saws are referred to as chain saws for short, and are generally used for forest felling, lumber making, branching, etc., as well as lumber making in lumber yards, and sawing of railway sleepers. The sawing mechanism is a saw chain, and the power part is a gasoline engine. It is easy to carry and easy to operate, but the maintenance and repair are more complicated. If the chainsaw appears to be fueled and turned off, it does not work so vigorously, and the heater overheats, etc., it means that the chainsaw is broken.

1. Before the chain saw works, let it run at a low speed for a few minutes, and see that the chain saw lubricating saw chain oil weighs an oil line before starting to work. When working, the accelerator can be set to use at high speed. Before finishing a tank of oil, you need to rest for a period of time, roughly 10 minutes. After the work is completed, the heat sink of the chain saw needs to be cleaned to ensure the normal heat dissipation of the machine.

2. The air filter of the chain saw needs to be dedusted every 25 hours. If you encounter special circumstances, you can adjust it yourself. The foam filter element can be cleaned with washing liquid or gasoline, and then washed again with clean water, squeezed to dry, then soaked in engine oil, and then installed after squeezing off excess oil.

3. When using a new chainsaw, pay attention to the tightness of the saw chain, so as to be able to push the saw chain to rotate. Use the hand-held saw chain. The guide teeth are parallel to the guide plate. After using it for a few minutes, pay attention to observe it again, and repeat it several times. .

When using a chainsaw, ensure that there are no creatures within 20 meters around, and check whether there are hard objects, stones, etc. on the grass to ensure safety. When the chain saw needs to be left unused, clean the machine body, let go of the mixed fuel, and burn out the fuel in the carburetor; remove the spark plug, add 1-2ml of two-stroke engine oil to the cylinder, pull the starter 2-3 times, install Put on the spark plug.

4. If the chainsaw has refueling and flameout, does not work so vigorously, and the heater overheats, etc., it is generally a problem with the filter. Therefore, before work, it is necessary to check the filter. A clean and qualified filter should be observed under sunlight, and it should be thorough and bright. Otherwise, it is unqualified. When the filter of the chainsaw is not clean enough, it should be washed with hot soapy water and dried. A clean filter can ensure the normal use of the chainsaw.

5. When the saw teeth of the chain saw become unsharp, you can use a special file to rest the cutting teeth of the saw chain to ensure the sharpness of the saw teeth. At this time, it should be noted that when filing with a file, it should be filed along the direction of the cutting teeth, not in the opposite direction. At the same time, the angle between the file and the chain saw chain should not be too large, preferably 30°.

6. Before using the chain saw, the chain saw oil should be added. The advantage of this is that it can provide lubrication for the chain saw, reduce the frictional heat between the chain saw chain and the chain saw guide plate, and protect the guide plate. Also protects the chain saw chain from premature failure.

7. After the chain saw is used, it is also necessary to maintain the chain saw, so that the work efficiency can be guaranteed when the chain saw is used next time. The first is to remove the oil inlet hole at the root of the chain saw guide plate and the impurities in the guide plate groove to ensure the smoothness of the oil inlet hole. Secondly, the sundries should also be cleared in the guide plate head, and a few drops of engine oil should be added.
