MAINTENANCE

Important: Use only good grade 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. We recommend premium hydraulic oil.
Adding oil
1. With ram plunger fully lowered and air supply
disconnected, set jack in its upright, level position.
Remove oil filler screw.
2. Fill with oil until just below the rim of the oil filler hole.
Reinstall the oil filler 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 air supply
disconnected, remove the oil filler screw.
2. Lay the jack on its side and drain the fluid into a
suitable container.

Lubrication
Air pump should be internally lubricated before each
use. Use good quality air tool lubricant. If no inline oiler
is used, pour a teaspoon of air tool oil into the air control
valve inlet. Operate the jack with air pressure to fully
distribute the oil inside the air motor.
Cleaning
Periodically check the ram for signs of rust/corrosion. Clean
as needed and wipe with oily cloth.
Note: Never use sandpaper or abrasive material on
ram surface!
Storage
When not in use, store the jack with ram plunger fully
retracted and air supply disconnected.
