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 (800) 533-6127.
