MAINTENANCE
Important: Use only good quality
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. The
manufacturer recommends only quality
grade hydraulic jack uid.
Adding oil
1. With saddle fully lowered, set jack in
upright, level position. Locate and
remove vent screw.
2. Fill with oil until ~3/16” above the inner
cylinder as seen from the oil ller hole.
If the oil level is too low, the jack will
not raise to its advertised maximum
height. Reinstall vent screw.
Changing oil
For best performance, completely
replace uid supply at least once per
year.
1. With saddle fully lowered, remove the
vent screw and drain the uid into a
suitable container.
2. Fill with oil until ~3/16” above the
inner cylinder as seen from the oil
ller hole. Reinstall the vent screw.

OPERATION
Lifting
Only attachments and/or adapters
supplied by the manufacturer
shall
be used. Lift only on areas
of the vehicle
as specied by the
vehicle manufacturer.
1. Follow the vehicle manufacturer’s
recommended guidelines for lifting.
Engage the emergency brake
and chock unlifted wheels in both
directions to prevent inadvertent
vehicle movement.
2. Locate and close the release valve by
turning the handle clockwise until rm
resistance is felt.
3. Center jack saddle under lift point.
4. Verify lift point then use handle pump
to contact lift point. To lift, pump handle
until load reaches desired height.
5. Immediately Transfer the load to
appropriately rated jack stands.
NEVER use this jack as a
stand alone device. After lifting,
immediately support the lifted
vehicle with a pair of appropriately
rated vehicle stands.
Overloading may cause hydraulic
system failure.
Lowering
Clear all tools and personnel
before lowering vehicle. Open
release valve slowly! The further
release valve (handle) is turned
counter-clockwise, the faster the
load will come down. Maintain
control of the rate of speed at
which the load lowers at all times.
1. Raise load high enough to clear the
jack stands.
2. Carefully remove jack stands.
3. Slowly turn release valve (handle)
counter-clockwise, but no more than
1/2 full turn. If the load fails to lower:
a. Use another jack to raise the ve-
hicle high enough to reinstall jack
stands.
b. Remove the malfunctioning jack
and then the jack stands.
c. Using the functioning jack, lower the
vehicle.
4. After
removing jack from under
vehicle, push saddle down to reduce
ram exposure to rust and contamination.

Note: Dispose of hydraulic uid
in accordance with local
environmental regulations.
Lubrication
A periodic coating of light lubricating
oil to pivot points, axles and hinges will
help to prevent rust and assure that
wheels, casters and 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
Lower the saddle to its lowest position
when not in use.
