Safety Precautions
Operating Instructions
CAUTION: To prevent personal injury and damage to equipment,
•
Study, understand, and follow all warnings and instructions. If the operator cannot read this
document, operating instructions and safety precautions must be read and discussed in
the operator’s native language.
•
Before using the service jack to lift a vehicle, refer to the vehicle service manual to determine
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. Take corrective action if any of the following conditions are found: cracked or
damaged housing; excessive wear, bending, or other damage; leaking hydraulic fluid; scored
or damaged piston rod; loose hardware; modified or altered equipment.
•
A load must 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,
and the hand brake released.
•
Use the jack for lifting purposes only. Stay clear of a lifted load. Place support stands under
the axles before working on the vehicle. Do not move or dolly the vehicle while on the jack.
•
Center the load on the jack saddle. Off-center loads can damage seals and cause jack failure.
Lift only dead weight.
•
Do not use blocks or other extenders between the saddle and the load being lifted.
•
Do not modify the jack or use adapters unless approved or supplied by Jackco.
•
Lower the jack slowly and carefully while watching the position of the jack saddle.
•
Use only automatic transmission fluid. 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.
Setup
1. Loosen the screw on the front of the handle socket.
2. Grease the socket opening. Insert the handle.
3. Torque the screw to 120 in. lbs.
Operation
1. Close the release valve by turning the handle clockwise (CW) as far as it will go.
2. Position the jack under the vehicle. CAUTION: Use the manufacturer’s recommended lifting points on the chassis.
3. Pump the jack handle to raise the saddle to the contact point.
3. Check the placement of the jack; the load must be centered on the jack saddle. CAUTION : 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 stable support. Before making repairs on
the vehicle, lower it onto the support stands by slowly and carefully turning the handle counterclockwise (CCW).
