The treatment methods are: straighten out the ring chain; adjust the relative position of the pawl and the pressure chain frame or replace the lubricating pin shaft, etc.

　　4. The motor vibrates or is noisy. The reasons for the failure are: the brake disc is unbalanced or broken, the brake disc is not fastened, the bearing loses oil or fails, the gear meshes are not smooth, oil loss or serious wear, motor current sound or vibration. The treatment methods are: fasten the brake disc nut; replace the brake disc or re-adjust the balance; replace the gear and lubrication at the output end of the motor shaft; replace the bearing; check the motor, and replace the motor if it is damaged.
