Pay attention to the following issues in the use and maintenance of the chain:

When starting the chain, first check whether the chain is running normally and whether the tightness of the saw chain is normal.

Remember to close the chain brake before starting, so as to stop the chain and prevent danger during starting. But release the chain brake before work, otherwise the bearing will be damaged.

When the chain rotates, be careful not to rub against the ground or other objects.

The chain should be oiled and painted with anti-rust paint in time. Once the chain is rusted, it should be replaced in time to improve work efficiency.

The chain should be checked and maintained frequently, and the chain should be repaired in time if the chain is broken and the cause should be found out.
