1. When installing the chain, ensure that its tightness is appropriate. Too tight will increase the wear of chains and gears, and too loose will easily lead to chain skipping and chain detachment, which will affect the use efficiency.

2. When the chain is seriously worn, the hoist chain and sprocket should be replaced at the same time to ensure accurate matching between parts. 3. The old and new chains cannot be mixed, because the wear degree of the old and new chains of the hoist is different, and their bearing capacity is also different. Mixed use is easy to cause chain breakage.

4. Fill the chain with lubricating oil in time during use. Lubricating oil can reduce the wear between parts and ensure the normal operation of the chain.

5. After the operation, the chain should be cleaned and rusted to avoid chain corrosion.
