repair of vehicle components. After lifting,
loads must be immediately supported by
appropriately rated jack stands. Check
with vehicle owner's manual for proper lift
points.

load supported only by a jack.
ALWAYS use adequately rated jack
stands. Immediately transfer loads
to appropriate jack stands.
OPERATION
Lifting
1. Place the vehicle in the park gear.
2. Engage the emergency brake.
3. Chock the wheels securely to prevent
inadvertent vehicle movement.
4. Locate and close the release valve by
turning release knob clockwise, firmly.
5.Centerjacksaddleunderliftpoint. Refer

manualto locate approvedliftingpoints
on the vehicle.
6. Verify lift point then use handle pump to
contact lift point. To lift, pump handle
until load reaches desired height.
7. Transfer the load immediately to
appropriately rated jack stands.
To lower load
1. Raise load high enough to clear the
jack stands.
2. Remove jack stands, carefully. (always
used in pairs).
3. Slowly turn the release knob counter-
clockwise, but no more than 1/2 turn.
If the load fails to lower:
a. Use another jack to raise the
vehicle high enough to reinstall jack

b.Remove the malfunctioningjackand
then the jack stands.
c. Using the functioning jack, lower
the load by turning the operating
handle counterclockwise, but no
more than 1/2 turn.
4. Push saddle down to reduce ram
exposure to rust and contamination
after removing the jack from under the
load.
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
failure of the jack and the potential for
sudden and immediate loss of load. We
recommend Mobil DTE 13M.
Addingoil
1. Lower saddle fully.
2. Set jack in its upright, level position.
3. Locate and remove air vent screw
4. Fill with oil until ~3/16" above the inner
cylinder as seen from the air vent
screw hole.
5. Reinstall the air vent screw
Changing oil
For best performance and longest life,
replace the complete hydraulic fluid 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
fluid into a suitable container.
Note: Dispose of hydraulic fluid in
accordance with local regulations.
4. Fill with oil until ~3/16" above the inner
cylinder as seen from the air vent
screw hole.
5. Reinstall the air vent screw.
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.
