MAINTENANCE
NOTICE: Use only a 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 failure of the jack and the potential for sudden
and immediate loss of load. Hein-Werner hydraulic jack oil HW93291 or equivalent is recommended.

1. Lower saddle fully.
2. Set jack in its upright, level position.
3. Locate and remove air vent screw.
4. Follow the BLEEDING/VENTING Trapped Air procedure on page 3.
5. Reinstall the air vent screw.
Changing oil
For best performance and longest life, completely replace hydraulic uid at least once a year.
1. Lower saddle fully.
2. Remove the air vent screw.
3. Lay the jack on its side and drain the uid into a suitable container.
NOTICE: Dispose of hydraulic uid in accordance with local environmental regulations.
4. Fill reservoir with oil and follow the BLEEDING/VENTING Trapped Air procedure on page 3.

Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help prevent rust and keep wheels, cas-
tors and pump assemblies moving freely.
Cleaning
Periodically check pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth .
NOTICE: Never use sandpaper or abrasive material on ram or pump piston.
Storage
Lower the saddle to its lowest position when not in use.
