How to fix a Performance Tool W1626 handle that raises?
- JJeffrey AndersonAug 12, 2025
If the handle raises, here are a few things to check: * The power unit may be low in fluid. Add clean hydraulic jack fluid to the level of the filler after removing the filler plug with the jack on a level surface and in the down position. * The power unit could be air bound. Open the release valve at least two full turns and pump the handle at least 20 full strokes to purge air. * The valve may not be closing completely. Seat the valves by closing the release valve, manually raising the lifting arm as high as possible with the jack in the fully lowered position, and then opening the release valve to let the jack descend. * There may be too much hydraulic oil inside the jack. Check and adjust the oil level if necessary.
