Setup
Assemble the Handle
1. Loosen the thumb screw on the back of the handle socket.
2. Grease the socket opening. Insert the handle.
3. Hand tighten the thumb screw.
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 handle all the way counterclockwise.
2. Pump the jack handle six full strokes.
3. Close the release valve by turning the handle all the way clockwise.
4. Pump the jack handle until the lift arm is fully extended.
5. Lower the lift arm by turning the handle counterclockwise. If the jack does not immediately respond, repeat Steps 2–4.
WARNING: To prevent personal injury and/or damage to equipment,
•Study, understand, and follow instructions and safety precautions, including ASME PALD Part 10
for service jacks. If the operator cannot read these instructions, operating instructions and safety
precautions 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.
•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 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 obstruction while lifting
or lowering the vehicle. The wheels of the vehicle must be in the straight-ahead position, with the
hand brake released.
•Center the load 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 use
blocks or other extenders between the saddle and the load being lifted.
•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.
•Do not modify the jack, or use adapters, unless approved or supplied by OTC.
This guide cannot cover every situation, so always do the job with safety first.
Safety Precautions
Operating Instructions
1. Close the release valve by turning the handle completely counterclockwise.
2. Positionthe jack underthe vehicle using the manufacturer’s recommended lifting points on the chassis. Thejack must befree
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.
3. Pump the jack handle until the saddle touches the vehicle. Check the placement of the jack; the load must be centered on the jack
saddle. IMPORTANT: Avoid wheel obstructions such as gravel, tools, or uneven expansion joints.
4. Finish lifting the vehicle by pumping the handle. Do not attempt to raise the jack beyond its
travel stops.
5. Place approved support stands under the vehicle at points that will provide
stablesupport.Beforeworkingonthevehicle,SLOWLYlowerthevehicleonto
