Do you know the knowledge of chain saw chain adjustment and repair of chain saw accessories?

1. When adjusting the chain saw chain, loosen the guide plate compression nut, use a screwdriver to tighten the guide plate adjustment screw, and turn the guide plate to the right to extend the guide plate and tighten the saw chain. To adjust the tightness, gently lift the saw chain by hand in the middle of the guide plate, so that the gap between the bottom end of the middle guide tooth and the outer use of the guide plate is about 1mm, and then tighten the guide plate compression nut after adjustment.

2. When replacing a new chain saw chain, lightly add the throttle after adjustment, drive the saw chain, and run in from slow to fast. During the running-in process, it is necessary to pump lubricating oil continuously, and then adjust the tension again after running-in. During use, if the saw chain is found to be loose, it should be adjusted in time.

3. The trimming of the teeth of the chain saw chain should be trimmed according to the original blade edge of the saw chain.
