Safety Precautions
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.
Setup
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.
Operating Instructions
(Refer to illustrations above)
Control rod in Position A: Allows you to pump jack using the handle.
Control rod in Position B: Locks handle in place.
Release Knob
Position A
Control Rod
Position B
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.

Preventive Maintenance
IMPORTANT: Dirt is the greatest single cause of failure in hydraulic 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 Figure 2, and regularly (at least once per month) lubricate the moving
parts shown.
3. Add grease to upper arm grease nipple (shown) every three months.
4. Replace the oil in the reservoir at least once per year. To check the oil level,
place the service jack on level ground and lower the lift arm completely.
Remove the filler plug located under the top shroud. The oil level should be
within 3/8" of the filler plug hole. If necessary, add approved anti-wear
hydraulic jack oil, and install the filler plug again. IMPORTANT: The use of
alcohol, hydraulic brake fluid, detergent motor oil, or transmission oil could damage the seals and result in jack failure.
5. Inspect the jack before each use. Take corrective action if any of the following problems are found:
a. Cracked or damaged housing e. Malfunctioning swivel heads or adjusting screws
b. Excessive wear, bending, or other damage f. Loose hardware
c. Leaking hydraulic fluid g. Modified or altered equipment
d. Scored or damaged piston rod
