7.0 MAINTENANCE AND CARE INSTRUCTIONS

You should inspect the jack before each use. Check the device for leaking hydraulic fluids,
damaged and/ or lost parts. Should any defects be found, the jack must be inspected
immediately. Any jack that shows damage, is badly worn, or does not function as intended must
be repaired by the service department. It is recommended that an inspection be performed
annually by an authorized repair facility. Any defective parts, decals or warning labels should then
be replaced with new ones at the time of inspection.
Oiling:
All moving joints must be oiled on a regular basis. Oil all elevator arm joints, front wheels and
rear roller.
The owner and user is responsible for intact storage of warning signs and notices, and
