Bleeding Air from the System
Air can accumulate within a hydraulic system during shipment or if the automatic transmission fluid (ATF) supply runs too
low. This entrapped air causes the jack to respond slowly or feel “spongy.” The following procedure bleeds air from the
system.
1. Remove the jack from service, and place it on a level surface.
2. Open the release valve by turning the handle all the way counterclockwise (CCW).
3. Pump the handle six full strokes.
4. Close the release valve by turning the handle all the way clockwise (CW).
5. Pump the handle until the lift arm is fully extended.
6. Lower the lift arm by turning the handle all the way counterclockwise (CCW).
7. Test the jack for normal operation. If the lift pad doesn’t rise to the correct height, repeat Steps 2–6. If this doesn’t solve
the problem, call the OTC Technical Services Dept. at [phone].

Parts List & Operating Instructions Form No. 107372
Safety Precautions
CAUTION: To prevent personal injury and damage to equipment,
•Read, understand, and follow all instructions, 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.
•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 any obstructions
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.
•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 OTC.
•Lower the jack slowly and carefully while watching the position of the jack saddle.
•Use only automatic transmission fluid (ATF). The use of alcohol or hydraulic brake fluid could damage seals
and result in jack failure.
This guide cannot cover every situation, so always do the job with safety first.
Operating Instructions
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. IMPORTANT: Use the manufacturer’s recommended lifting points on the
chassis.
3. Pump the jack handle to raise the saddle to the contact point.
4. 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.
5. Finish lifting the vehicle by pumping the handle. Do not attempt to raise the jack beyond its travel stops.
6. 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).

Preventive Maintenance
IMPORTANT: The greatest single cause of failure in hydraulic units is dirt. 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. Regularly lubricate the moving parts in the wheels, arm, handle, and pump roller pin.
3. Replace the automatic transmission fluid (ATF) in the reservoir at least once per year. To check the ATF level, lower
the lift arm completely. Remove the rubber filler plug. The ATF level should be at the bottom of the filler plug hole. If
necessary, add ATF, and install the filler plug. IMPORTANT: The use of alcohol or hydraulic brake fluid could
damage the seals and result in jack failure.
4. Inspect the jack before each use. Take corrective action if any of the following problems are found:
a. cracked, damaged housing c. leaking hydraulic fluid e. loose hardware
b. excessive wear, bending, other damage d. scored, damaged piston rod f. modified equipment
5. Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash external surfaces
of the jack.
Troubleshooting Guide
Repair procedures must be performed in a dirt-free environment by qualified personnel who are familiar with this
equipment. CAUTION: All inspection, maintenance, and repair procedures must be performed when the jack is free
of a load (not in use).
