to jack from overpumping. An internal safety valve prevents damage to jack from
overloading. Applications include automotive, truck, farm, industrial and construction.
These jacks are designed to meet applicable ASME/ANSI Standards.

3. Occasionally, hydraulic jacks become
air bound and will not function
properly. To correct this condition,
remove oil filler/vent plug. This will
allow any pressurized air to escape.
Check for proper oil level (see Adding
Oil, page 2), adjust as needed.
DO NOT OVERFILL! Reinstall oil filler/
vent plug.
4. Squirt a small amount of hydraulic jack
oil on pistons and lightly lubricate all
moving parts of jack.

Operation

Off-centered loads
and loads lifted while
jack is not level may damage the jack or
cause personal injury.

1. Prevent inadvertent vehicle movement
by fully engaging emergency brake,
putting transmission in park. Use
wheel chocks in pairs on the wheel
diagonally opposed to the wheel or
axle lifted.
2. Close release valve by turning
the release knob on top of handle
clockwise until it is firmly closed.
3. Position jack under load and align
to the lift point suggested by vehicle
manufacturer.
4. Operate jack by pumping the handle,
foot pedal until saddle contacts load
point. Ensure load is centered on
saddle. Then operate jack until load
reaches desired height.
nOtE: Never use foot pedal to raise
load.
This is a lifting
device only. The
load must be supported immediately by
other appropriate means.
Keep hands, feet,
and clutter clear of
ground area when lowering the load.
