The tightness of the chainsaw chain should be suitable, otherwise too tight will increase the power consumption and the bearing will be easy to wear; The tightness level of the chain is: lift or press down from the middle of the chain, and the center distance between the two sprockets is about 2%-3%. The new chain is too long or stretched after use, which is difficult to adjust. , but it needs to be an even number.

The chain link of the chainsaw chain should pass through the reverse side of the chain, the locking plate should be inserted outside, and the opening of the locking plate should be in the opposite direction of rotation. After the sprocket is seriously worn, it should be replaced with a new sprocket and a new chain at the same time to ensure good meshing. A new chain or a new sprocket cannot be replaced alone. Otherwise, the meshing will be bad and the wear of the new chain or the new sprocket will be accelerated. After the sprocket tooth surface of the chainsaw chain is worn to a certain level, it should be turned over and used in time (referring to the sprocket used on the adjustable surface). to extend the operating time. Manually supply oil with oil pot or oil brush regularly; drip oil lubrication, use oil cup to drip oil through the oil pipe to the gap between the inner and outer chain plates of the loose edge; oil bath lubrication or splash lubrication, use a sealed transmission box, the former chain and sprocket Part of it is immersed in oil, the latter uses a larger diameter oil slinger to splash oil; the oil pump is pressure-sprayed for lubrication, and the oil pump is used to continuously supply oil to the chainsaw chain through the oil pipe, and the circulating oil can play the role of lubrication and cooling. Only the places where the speed is very slow and cannot supply oil can be replaced with grease.

After the sprocket of the chainsaw chain is seriously worn, the new sprocket and new chain should be replaced at the same time to ensure good meshing. You can't just replace a new chain or a new sprocket alone. Otherwise, it will cause poor meshing and accelerate the wear of the new chain or the new sprocket. After the sprocket tooth surface of the chainsaw chain is worn to a certain extent, it should be turned over in time for use.
