1. Keep the machine surface clean at all times. Regularly check the internal structure for damage, ensuring the small gear in the rocker arm moves flexibly and reliably, and the lifting sleeve moves freely.
2. The friction surfaces between the lifting sleeve and the housing must be lubricated regularly. Other lubrication holes should also be lubricated periodically.
3. For safety reasons, never overload the machine, operate it when it is malfunctioning, or use multiple jacks simultaneously to avoid potential hazards.
