Bleeding 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 air do the following:
1. Open the release valve by turning the handle all the way
counterclockwise.
2. For Hydraulic Units - Pump the handle six full strokes.
For Air Assist Hydraulic Units - Activate air pump six times.
3. Close the release valve by turning the handle all the way clockwise.
4. For Hydraulic Units - Pump the handle until the lift arm is fully
extended. For Air Assist Hydraulic Units - Activate air pump until lift
arm is fully extended.
5. Lower lift arm by turning the handle all the way counterclockwise.
If the jack does not immediately lower, repeat steps 2–4.
To ensure the safety features of your service jack are not
compromised, OTC offers a limited selection of replacement parts.
