Setup
Assemble the Handle
1. Loosen the bolt (Item 64) on the handle socket (60). NOTE: Item numbers refer to the parts list on page 1.
2. Insert the handle.
3. Tighten the bolt.
WARNING: To prevent personal injury and/or damage to equipment,
•Study,understand,andfollowallinstructionsandsafetyprecautions.Iftheoperatorcannotread
these instructions, the safety precautions and instructions must be read and discussed in the
operator’s native language.
•Beforeusingtheservicejacktoliftavehicle,refertothevehicleservicemanualforrecommended
lifting surfaces on the vehicle chassis.
•Wear eye protection that meets ANSI Z87.1 and OSHA standards.
•Inspectthejack before each use; do not use the jack if it’s damaged, altered, or in poor condition.
•Use the jack for lifting purposes only; use approved safety stands to support the axles before
working on the vehicle.
•Never exceed the rated lifting capacity of the jack.
•Use the jack on a hard, level surface. The jack must be free to roll without any obstructions while
lifting or lowering the vehicle. The wheels of the vehicle must be in the straight-ahead position,
and the hand brake must be released.
•Center the axle on the jack saddle. Off-center loads can damage seals and cause jack failure.
•Lift only dead weight. Do not move the jack while it is supporting a vehicle.
•Stay clear of lifted loads. Use approved safety stands to support the axles before making repairs.
•Do not adjust the safety valve.
•Lower the jack slowly and carefully while watching the position of the jack saddle.
•Use only approved hydraulic fluid (Chevron AW Hydraulic Oil MV or equivalent). The use of alcohol, hydraulic
brake fluid, or transmission oil could damage seals and result in jack failure.
This guide cannot cover every situation, so always do the job with safety first.
Safety Precautions
Air Bleed Instructions
Air can accumulate within a hydraulic system during shipment or after
prolongeduse. Thisentrappedaircausesthejack torespondslowlyortofeel
“spongy.”Toremove the air,followthe instructions forboththe manual pump
and the air pump:
Bleed Air — Manual Pump
1. Open the release valve by turning the release knob counterclockwise.
2. Pump the jack handle six full strokes.
3. Close the release valve by turning the release knob clockwise.
4. If the jack does not immediately respond to pumping the handle, repeat
Steps 1–3.
Bleed Air — Air Pump
1. Place the jack on a level surface.
2. Open the release valve by turning the release knob counterclockwise.
3. Run the air pump for 20 seconds, then close the release valve by turning
the release knob clockwise.
4. Pump the jack pedal until the jack reaches its maximum height.
5. Open the release valve by turning the release knob counterclockwise,
lower the jack to its minimum height.
6. If the jack does not immediately respond to the air pump, repeat steps 1–
5, or follow the priming instructions on the next page.

Operating Instructions
(Refer to Figure 1)
Control rod in Position A: Allows you to pump the jack using the handle.
Control rod in Position B: Locks the handle in place in three different positions.
1. Connect the shop air supply to the jack. (Shop air should be clean, dry, and regulated at 85–142 psi.)
2. Turn the release knob completely counterclockwise, and place the control rod in Position A.
3. Position the jack under the vehicle using the manufacturer’s recommended lifting points on the chassis. The jack
must be free to roll without any obstructions while lifting or lowering the vehicle. The wheels of the vehicle must be in
the straight-ahead position, with the emergency brake released.
4. Turn the release knob on the jack completely clockwise. Operate the air valve, pump the jack handle, or pump the foot
pedal until the saddle touches the vehicle. Check the placement of the saddle lugs. Finish lifting the vehicle.
5. Place approved safety stands under the vehicle at points that will provide stable support. Before working on the
vehicle, SLOWLY lower the vehicle onto the safety stands by turning the release knob counterclockwise.

Priming the Air Pump
If air cannot be bled using the air pump air bleed procedure, the air pump
has lost its prime. To prime the pump:
1. Remove the cover board (Item 26).
2. Loosen the bolt (Item 46; also see Figure 2) one-half turn.
3. Close the release valve by turning the release knob clockwise.
4. Run the air pump while repeatedly tightening and loosening the bolt. (A
small amount of oil may seep from underneath the bolt during this
process).
5. When the piston begins to rise, tighten the bolt.
6. Verify the jack will rise to its full height; add oil to the reservoir if
necessary.

IMPORTANT:Dirtisthegreatestsinglecauseoffailureinhydraulic
units. Keep the service jack clean and well lubricated to prevent
foreign matter from entering the system. If the jack has been
exposed to rain, snow, sand, or grit, it must be cleaned before it
is used.
1. Store the jack in a well-protected area where it will not be exposed
to corrosive vapors, abrasive dust, or any other harmful elements.
2. Refer to the illustration, and regularly (at least once per month)
lubricate the moving parts shown.
