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.
