Why won't my Performance Tool Jack lift to full height?
- AApril SandersJul 28, 2025
Your Performance Tool Jack might not be lifting to its full height due to several reasons. It could be that the power unit is low on fluid. To fix this, with the jack on a level surface and in the down position, remove the filler plug and add clean hydraulic jack fluid until it reaches the filler level. Another possibility is that the power unit is air bound. To resolve this, open the release valve a minimum of 2 full turns and pump the handle a minimum of 20 full strokes to purge the air from the system. Also, the valve may not be closing completely. To seat the valves: close the release valve, with the jack in the fully lowered position, manually raise the lifting arm as high as possible, then open the release valve and allow the jack to descend to the lowered position.
