Parts List & Operating Instructions
WARNING: To prevent personal injury and damage to equipment,
• Read, understand, and follow all instructions and safety precautions.
• Before using the service jack to lift a vehicle, refer to the vehicle service manual for recommended lifting
surfaces on the vehicle chassis.
• Wear eye protection that meets ANSI Z87.1 and OSHA standards.
• Inspect the jack before each use; do not use the jack if it's damaged, altered, or in poor condition.
• Use the jack for lifting purposes; 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.
Assemble the Handle
1. Loosen the bolt on the handle socket.
2. Insert the handle.
3. Tighten the bolt.
Bleed Air from the Service Jack
Air can accumulate within a hydraulic system during shipment or after
prolonged use. This entrapped air causes the jack to respond slowly or feel
"spongy." To remove the air:
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. Pump the jack handle or foot pedal until the lift arm is fully extended.
5. Lower the lift arm by turning the release knob counterclockwise. If the
jack does not immediately respond, repeat Steps 2–4.
Control rod in Position A: Allows you to pump jack using the handle.
Control rod in Position B: Locks handle in place.
Lifting Operation
1. Turn release knob counterclockwise fully.
2. Position the jack under the vehicle. IMPORTANT: Use the vehicle manufacturer's recommended lifting points on the chassis.
3. Pump the jack handle or the foot pedal until the saddle touches the vehicle. Check the placement of the saddle lugs. Finish lifting the
vehicle.
4. 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.
Lowering Operation
1. SLOWLY turn release knob counterclockwise.
