Maintenance and lubrication
Important:
Use only a quality 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 failure of the jack and the
potential for sudden and immediate loss of load.
Adding oil
1. With saddle fully lowered, set jack in its
upright, level position. Locate and remove oil
filler plug.
2. Fill with oil even with the bottom of oil filler
plug hole. Reinstall the oil filler plug.
Note:
At an ambient temperature from 27F to
113F use machine oil (GB443-84) N15.
Sufficient filtered hydraulic oil should be main-
tained in the jacks, otherwise the rated height
cannot be reached.
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.
3. Note: Dispose of hydraulic fluid in accordance
with local regulations.
4. Fill with oil even with the bottom of oil filler
plug hole. Reinstall the oil filler plug.
Lubrication
A periodic coating of light lubricating oil to pivot
points will help ensure that pump piston linkages
move freely.
Note:
Never apply oil to the saddle. If saddle ex-
tension threads require lubrication; clean thread
surfaces with a clean, dry cloth, then apply a
drop of bearing grease to the threads. Distribute
as evenly as possible along the threaded post.
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
Store the jack with the pump piston, ram plunger,
and saddle fully lowered. Ensure the release
valve is open, but never more than ½ turn. This
will help prevent rust and corrosion to those
critical surfaces.
