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 jack oil.
Adding oil
1. With lifting arm fully lowered set jack in its upright,
level position. Locate and remove oil filler plug.
2. Fill with oil until ~3/16" above the inner cylinder as
seen from the oil filler hole. Reinstall oil filler plug.
Changing oil
For best performance and longest life, replace the
complete fluid supply at least once per year.
1. With lifting arm fully lowered, remove oil filler plug.
2. Lay the jack on its side and drain the fluid into a
suitable container.
Note. Dispose of hydraulic fluid in accordance with
local regulations.
3. Fill with oil until ~3/16" above the inner cylinder as
seen from the oil filler hole. Reinstall oil filler plug.

Lubrication
A periodic coating of light lubricating oil to pivot points,
axles and hinges will help to prevent rust and assure that
wheels, casters and pump assemblies move freely.
Cleaning
Periodically check the pump piston and ram for signs
of rust or corrosion. Clean as needed and wipe with
an oily cloth.
Note: Never use sandpaper or abrasive material on
these surfaces!
Storage
When not in use, store the jack with lifting arm fully
lowered.
