Description
Westward hydraulic
Quick Lifting
jacks are used for lifting part of a total vehicle (i.e.,
one wheel). Jacks are equipped with a built-in by-pass device to prevent damage
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.

General Safety Information
Study, understand,
and follow all
instructions before operating this device.
Lifting device only. Intended use is for
lifting part of a total vehicle, only one
wheel or axle at a time. Immediately after
lifting, support vehicle with appropriate
means. Do not exceed rated capacity. Use
only on hard, level surfaces capable of
sustaining rated capacity loads. Lift only
on those areas of the vehicle as specified
by the vehicle manufacturer. Ensure that
the lift point is properly centered on the
jack saddle. Always wear safety glasses
when using this equipment. Inspect
jack before each use. Do not use if bent,
broken, leaking, or damaged components
are noted. No alteration of this product
is allowed. Do not use this device for
any purpose other than that for which it
was intended. Failure to heed any one or
combination of these warnings may result
in severe personal injury and/or property
damage.
Assembly
Use figure 1 as reference.
1. Assemble the handle to handle socket
by inserting the handle piece into
the socket; align the handle with jack
chassis, then tighten the hexagon nut
securely.
2. Try to operate the release mechanism
by turning the release knob located
on top of the handle clockwise and
counterclockwise to see if release shaft
fits together well.
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.
LIftInG
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.
