Maintenance and Servicing
Procedures not specifically explained in this manual must be performed only by a qualified technician.
WARNING!
TO PREVENT SERIOUS INJURY FROM TOOL FAILURE: Do not use damaged equipment. If abnormal noise or
vibration occurs, have the problem corrected before further use.
1. BEFORE EACH USE, inspect the general condition of the equipment. Check for:
• loose hardware,
• misalignment or binding of moving parts,
• visibly leaking hydraulic fluid,
• cracked or broken parts, and
• any other condition that may affect its safe operation.
2. Before each use and after the inspection, thoroughly test the Jack for proper operation prior to its actual use. If the
Jack appears not to be working properly, follow Bleeding instructions.
3. Periodically, inject grease into the Zerk fitting on the main platform of the Transmission Jack.
4. Change the hydraulic oil at least once every three years:
a. With the Jack fully lowered, remove the Oil Filler Plug on the side of the Housing.
b. Tip the Jack to allow the old hydraulic oil to drain out of the Housing completely, and dispose of the old hydraulic oil
in accordance with local regulations.
c. With the Jack upright, completely fill the Housing with a high quality hydraulic oil (not included) until the oil just
begins to run out of the Oil Fill Hole.
d. Open the Release Valve and pump the Handle to bleed air from the system.
e. Reinstall the Oil Filler Plug.
5. Wipe dry with a clean cloth. Then, store the Jack in a safe, dry location out of reach of children and other non-
authorized people.
