Lowering
!
WARNING: Clear all tools and personnel before lowering load. Open release valve slowly. The further handle is
turned counter-clockwise, the faster the load will descend. Maintain control of the load at all times.
1. Raise load high enough to clear the jack stands, then carefully remove jack stands.
2. Slowly turn the Pump Handle counter-clockwise, but no more than 1/2 turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough to reinstall jack stands.
b. Remove the affected jack and then the stands.
c. Use the functioning jack to lower the vehicle.
3. After removing jack from under the load, push Ram Plunger and Handle Sleeve down to reduce 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
1. With Ram Plunger fully lowered and pump piston fully depressed, set jack in its upright, level position. Remove
Oil Filler Plug/Screw.
2. Fill with oil until just below the rim of the oil filler hole. Reinstall the Oil Filler Plug/Screw.
Changing oil
For best performance and longest life, replace the complete fluid supply at least once per year.
1. With Ram Plunger fully lowered and pump piston fully depressed, remove the Oil Filler Plug/Screw.
2. Lay the jack on its side and drain the fluid into a suitable container.
NOTICE: Dispose of hydraulic oil in accordance with local environmental regulations.
3. Fill with oil until just below the rim of oil filler hole.
4. Perform Bleeding/Venting Trapped Air procedure (page 2). Reinstall the Oil Filler Plug/Screw.
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
pump assemblies move freely.
Cleaning
Periodically check the pump piston and Ram Plunger for signs of rust or corrosion. Clean as needed and wipe with
an oily cloth.
NOTICE: Do not use sandpaper or abrasive material on ram or pump piston surfaces.
Storage
When not in use, store the jack with pump piston and Ram Plunger fully retracted and air supply disconnected.
