Note: 1. The tightness of the chain should be appropriate. Too tight will increase power consumption and the bearing will wear out easily. If the chain is too loose, it is easy to bounce and loosen the chain 2. The old chain can not be mixed with the new chain, otherwise it is easy to create an impact in the gearbox and pull the chain
