MAINTENANCE
Important: Use only a 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 poten-
tial for sudden and immediate loss of load. We recommend Hein-Werner HW93291 or equivalent.
Adding oil
1. With saddle fully lowered, set jack in its upright, level position. Remove oil filler plug.
2. Fill until oil is level with the 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 saddle fully lowered, set jack in its upright, level position. Remove the 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. Set jack in its level upright position.
4. Fill with oil until level with the 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 casters
and pump assemblies move freely.
Cleaning
Periodically check the ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.
Note: Never use sand paper or abrasive material on these surfaces !
Storage
When not in use, store the jack with saddle in lowest position.
Lower saddle:
Caution! Be sure all tools and personnel are clear before lowering load. Dynamic shock loads are created by quickly
opening and closing the release valve as the load is being lowered. The resulting of overload may cause hydraulic system
failure.
Slowly, gently turn release valve counterclockwise to lower saddle.
To avoid crushing and related
injuries:
NEVER work on, under or
around a load supported only
by a jack. Immediately
transfer the load to an
appropriate work station.
! WARNING
OPERATION
Raise saddle:
1. Turn release valve clockwise until firm. Pump handle
until load is contacted.
2. Follow vehicle manufacturers recommended
procedures for removing the load as outlined in vehicle
service manual or repair guide.
3. Secure load with provided chains. Ensure load's center
of gravity is centered on the saddle and load is stable
before moving jack.
