There are certain precautions for the maintenance of the chain saw's guide bar head. Do a good job of maintenance to protect the chain saw's guide bar, so that the chain saw can operate better and complete the work smoothly and safely.

Before using the chain saw chain, work should be done after the chain oil is thrown out, and should be soaked in the oil bowl after the work is over. Pay attention to the change of cutting chips during the work. When the saw teeth are not sharp, use a special file to rest the teeth of the saw tooth chain to ensure the sharpness of the saw teeth. The correct method of operation is to frustrate the tooth in the direction of the cutting tooth, and only frustrate the tooth in the direction of the tooth. Do not pull back. The most suitable angle between the file and the chain of the chain saw is 30°. Larger will make the chain saw chain more blunt, while the angle is too small, it will result in a non-durable condition, so the angle must be controlled properly, otherwise it will have an adverse effect on the chain saw chain and guide plate.

Also, to protect the guide bar head, the chain oil must be used correctly. Saw chain oil provides lubricating oil during the cutting process of the saw chain and wood, reduces the frictional heat between the chain saw chain and the chain saw guide plate head, and protects the chain saw guide plate. Before working, check whether the chain oil has been filled enough. After turning on the machine, you should wait until the chain oil is thrown out before you can work. The chain saw chain that lacks oil refining will be annealed at high temperature during work, causing the chain saw chain to be prematurely scrapped, and it will also cause the chain saw guide plate , And even shorten the service life of the chain saw.
