OPERATION

Lifting
!
WARNING: Only attachments and/or adapters supplied by the manufacturer shall be used.
1. Follow the vehicle manufacturer's recommended guidelines for lifting. Engage the vehicle's emergency brake and
chock each unlifted wheel in both directions to prevent inadvertent movement.
2. Close the release valve by turning the pump handle clockwise until firm resistance is felt.
3. Refer to the vehicle manufacturer owner's manual to locate approved lifting points on the vehicle. Center jack
saddle under lift point.
4. Pump handle until saddle contacts lift point. To lift, continue pumping handle until load reaches desired height.
5. Immediately transfer the load to appropriately rated jack stands.
Lowering
!
WARNING: Clear all tools and personnel before lowering vehicle. Open release valve slowly. The further the pump
handle is turned counter-clockwise, the faster the load will descend. Maintain control of load at all times.
1. Raise load high enough to clear the jack stands.
2. Remove jack stands.
3. Slowly turn the handle counter-clockwise, but no more than 1/2 full turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough to reinstall jack stands.
b. Remove the malfunctioning jack and then the jack stands.
c. Use the functioning jack to lower the vehicle.
4. After removing jack from under the vehicle, fully lower the saddle to reduce ram exposure to rust and
contamination.

MAINTENANCE

NOTICE: Use only good quality hydraulic jack oil. Avoid mixing different types of fluid and NEVER use brake fluid,
turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause premature failure of the jack and the
potential for sudden and immediate loss of load. Premium hydraulic jack oil is recommended.
Adding oil
Correct oil level allows the saddle to reach its advertised maximum height and its advertised minimum height.
NOTICE: Too much oil will prevent saddle from lowering completely. Too little oil will not allow the saddle to raise
completely.
1. With saddle fully lowered set jack in its upright, level position. Remove oil filler plug.
2. Fill until oil nearly covers the inner cylinder as seen from the oil filler hole. Reinstall the oil filler plug.
Changing oil
For best performance and longest life, replace the complete fluid supply at least once per year.
1. With saddle fully lowered, remove the oil filler plug.
2. Lay the jack on its side and drain the fluid into a suitable container.
NOTICE: Dispose of hydraulic fluid in accordance with local environmental regulations.
3. Fill until oil nearly covers the inner cylinder as seen from the oil filler hole. Reinstall the oil filler plug.
