Check and Refill Oil
Use hydraulic jack oil only. Do not use brake or transmission fluids or regular motor oil or any other fluids as they may
damage the seals.
(a) Turn the release valve counterclockwise to allow ram to fully retract. It may be necessary to apply force to the
saddle for complete lowering.
(b) With the jack in the level position, remove the oil fill plug. Stand jack in a vertical position with the handle socket
down. The oil should be level with the bottom of fill hole. If not, top off. Do not overfill. Always fill with new, clean
hydraulic jack oil.
(c) Replace oil fill plug and check jack operation.
(d) Purge air from system as required.
Air Purge Procedure
During shipment or after refilling oil, air may get into the hydraulic system causing poor lift performance. Purge system
for better performance.
(a) Turn the release valve fully counterclockwise to fully open the release valve.
(b) Pump handle rapidly several times
(c) Turn the release valve clockwise to close the release valve.
(d) Pump the handle until the lift arm reaches maximum height and continue to pump several times to remove trapped
air in the ram.
(e) Turn the release valve counterclockwise in one full turn and lower lift arm to the lowest position. Use force on saddle
if necessary.
(f) Carefully and slowly pinch oil fill plug to release trapped air.
(g) Turn the release valve clockwise to closed position and check for proper pump action. It may be necessary to
perform the above steps more than once to assure air is completely evacuated.
