MaIntenance
Important: Use only good grade hydraulic jack oil.
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 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 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 saddle fully lowered and pump piston fully
depressed, remove the oil filler screw.
2. Lay the jack on its side and drain the fluid 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 filler hole.
Reinstall the oil filler screw.
Lubrication
1. 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.
2. When used on a daily basis, air pump should be
internally lubricated before each use. Use only good
quality air tool lubricant. If no inline oiler is used, pour
a teaspoon of air tool oil into the inlet of the air control
valve. Simply operate the jack with air pressure to fully
distribute the oil inside the air motor.
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 and air supply disconnected.
Paint contains lead!
DO NOT sand or grind painted surface!
