PURGING AIR FROM THE SYSTEM
If air bubbles become trapped inside the hydraulic system during shipping or
transport, the efficiency of the jack will be reduced and the jack will feel
spongy.
1. Turn the control valve counter-clockwise, relieving the pressure inside the
jack.
2. Pump the handle several strokes to purge air from the system.
3. Turn the control valve clockwise raise the jack to its full height. Pump the
handle again several full strokes.
4. Test the jack and if efficiency is still low, repeat the above procedure with
the oil filler plug loosened. Check the oil level as described under
Maintenance.
5. The jack is now ready to use.
