If the chain saw is refueling and stalling, working less vigorously, or overheating the heating machine, it is generally a filter problem. Therefore, the filter should be inspected before work. A clean and qualified filter should be pierced and bright for observation under sunlight, otherwise it is unqualified. When the filter of the chain saw is not clean enough, it should be washed with hot soapy water and dried. A clean filter can ensure the normal use of the chain saw.

When the teeth of the chain saw become unsharp, you can use a special file to rest the teeth of the serrated chain to ensure the sharpness of the teeth. At this time, it should be noted that when using a file to frustrate, you must frustrate in the direction of the cutting tooth, not the other way around. At the same time, the angle between the file and the chain of the chain saw should not be too large, preferably 30 degrees.

Before using the chain saw, the chain oil should be added. The advantage of this is that it can provide lubrication for the chain saw, reduce the friction heat between the chain saw chain and the chain saw guide plate, and protect the guide plate. Protect the chain saw chain to avoid premature scrapping.

After the chain saw is used, the chain saw should be maintained so that the working efficiency can be guaranteed when the chain saw is used next time. The first is to remove impurities in the oil inlet hole and the guide plate groove at the root of the chain saw guide plate to ensure the smoothness of the oil inlet hole.
