Parts List & Operating Instructions

Air can accumulate within a hydraulic system during shipment, or if the oil 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 (800) 533-6127.

Setup

1. Loosen the thumb screw on the front of the handle socket.

2. Grease the socket opening. Insert the handle.

3. Torque the thumb screw to 150–200 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).

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, the arm, and the handle.

3. Replace the oil in the reservoir at least once per year. To check the oil level, lower the lift arm completely. Remove the

rubber filler plug. Oil level should be at the bottom of the filler plug hole. If necessary, add approved anti-wear hydraulic

jack oil, and install the filler plug. IMPORTANT: The use of alcohol, hydraulic brake fluid, or transmission oil 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

b. excessive wear, bending, other damage

5. Keep warning labels and instructional decals clean and readable. Use a mild soap solution to wash external surfaces

of the jack.
