Step 1:
Purging air from a hydraulic air bottle jacks is similar to the small trolley jacks. Start by loosening the release valve, and pumping the handle a few times.
Step 2:
Then, tip the bottle jack over so that the oil fill plug is facing upwards, and the unit is level.
Step 3:
Push the oil fill plug sideways with a flat screwdriver to allow the air to escape, be careful not to damage the plug. As with all hydraulic jacks, the air purge process may have to be repeated for maximum efficiency.
Step 4:
If you’re adding oil to the bottle jack, completely remove the fill plug and fill the jack until oil is level with the filler plug hole - when the jack is upright.
