MAINTENANCE
Important: Use only good grade hydraulic jack oil. Avoid
mixing different types of uid and NEVER use brake
uid, turbine oil, transmission uid, motor oil or glycerin.
Improper uid can cause premature failure of the jack
and the potential for sudden and immediate loss of load.
We recommend Mobil DTE 13M or equivalent.
Adding oil
1. With saddle fully lowered and pump piston fully
depressed, set jack in its upright, level position.
Remove oil ller screw.
2. Fill with oil until just below the rim of the oil ller screw
hole. Reinstall the oil ller screw.
Changing oil
For best performance and longest life, replace the
complete uid supply at least once per year.
1. With saddle fully lowered and pump piston fully
depressed, remove the oil ller screw.
2. Lay the jack on its side and drain the uid into a
suitable container.
Note: Dispose of hydraulic oil in accordance with local
regulations.
3. Fill with oil until just below the rim of the oil ller screw
hole. Reinstall the oil ller 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 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 pump piston and
ram fully retracted.
