Westward Operating Instructions and Parts Manual
Study, understand, and follow all
instructions before operating this device. Do not
exceed rated capacity. Use only on hard, level
surface. Lifting device only. Immediately after
lifting, support vehicle with appropriate means. Do
not move or dolly the vehicle while on the jack.
Ensure that the lift point is properly centered on
the jack saddle. Lift only on areas of the vehicle as
specified by the vehicle manufacturer. No
alteration of this product is allowed. Failure to
heed these warnings may result in severe personal
injury and/or property damage.
Assembly
(ref. Figure 1)
1. Insert the handle piece into the socket; align the handle
with jack chassis, then tighten the hex nut securely.
2. Operate the release mechanism by turning the
release knob located on top of the handle both
clockwise and counterclockwise. Release valve
shaft should fit properly.
3. Squirt a small amount of hydraulic jack oil on
pistons and lightly lubricate all moving parts of jack.
Preparation
1. Before using this product, read the operator's
manual completely and familiarize yourself
thoroughly with the product, its components and
recognize the hazards associated with its use.
2. Verify that the product and application are compatible.
If in doubt, contact Westward Customer Service.
3. To familiarize yourself with basic operation, turn the
release valve knob:
a. Clockwise until firm resistance is felt to further
turning. This is the 'CLOSED' release valve
position used to raise the saddle.
b. Counter-clockwise, but no more than 1/2 turn
from the closed position. This is the 'OPEN'
release valve position used to lower the saddle.
4. With saddle fully lowered and release valve fully
closed, pump the operating handle. If lift arm
responds immediately, jack is ready for use. If
jack does not respond, follow Bleeding/Venting
Trapped Air instruction below.
5. Ensure that jack rolls freely. Raise and lower the
unloaded saddle throughout the lifting range before
putting into service to ensure the pump operates
smoothly. Replace worn or damaged parts and
assemblies with Omega authorized replacement
parts only.
Bleeding/Venting Trapped Air
With the release valve in the OPEN position (step 3b.
above) and with saddle fully lowered, locate and
remove the oil filler plug/screw. Pump 6 to 8 full
strokes. This will help release any pressurized air
which may be trapped within the reservoir. Proper oil
level will vary from just covering the ram cylinder to
3/16" above it as seen from the oil filler hole. Reinstall
the oil filler plug/screw.
Operation
LIFTInG
1. Prevent inadvertent vehicle movement by fully
engaging emergency brake, putting transmission in
park. Use wheel chocks in pairs on all unlifted wheels.
Long Chassis Hydraulic Service Jack
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.
nOTICE:
Do not use foot pedal to raise load.
Clear all tools and personnel
when lowering the load.
LOwErInG
Slowly open the release valve by turning the handle
knob counterclockwise.
Avoid shock loads created by
quickly opening and closing the release valve as
the load is being lowered. Shock loads can cause
system failure and resulting in personal injury
and/or property damage.
MAInTEnAnCE
nOTICE:
When adding or replacing oil, always use a
good grade hydraulic jack oil. Do not use hydraulic
brake fluid, alcohol, glycerine, detergent motor oil or
dirty oil. Improper fluid can cause serious internal
damage to the jack rendering it inoperative.
ADDInG OIL
1. Position the jack on level ground and fully lower the
saddle. Remove oil filler vent screw.
2. Fill oil to within 3/8" of filler hole.
DO NOT OVERFILL. If overfilled, the jack will not
lower to published minimum height. If under filled,
the jack will not reach published maximum height.
Adjust fluid level as needed. Reinstall oil filler vent
screw before using jack.
rEPLACInG OIL
1. Remove oil filler vent screw.
2. Turn jack over and drain old oil out through oil
filler hole.
3. Refill with new oil through the oil filler hole.
nOTICE:
Do not allow dirt or other foreign material
to enter the hydraulic system when filling.
4. Perform Bleeding/Venting Trapped Air procedure.
LuBrICATIOn
1. Add lubricating oil to all moving parts as needed.
2. Apply grease to grease fittings periodically.
ruST PrEVEnTIOn
1. Check ram and piston periodically for signs of
corrosion. Clean as needed with an oily cloth.
2. When not in use, store jack with saddle and piston
fully retracted.
