1. When the engineering chain is enabled, first check whether the chain is running normally and whether the tightness of the chain is normal.
2. Remember to close the chain brake before starting, so as to stop the chain and prevent danger when starting. However, loosen the chain brake before working, otherwise it will damage the bearing.
3. Be careful not to rub against the ground or other objects when the chain is rotated.
4, the chain should be oiled in time to apply anti-rust paint, etc., once the chain is rusted, it should be replaced in time to improve work efficiency.
5, should always check and maintain the chain, the situation of broken chain disconnection should be repaired in time, and find out the reasons.
