QuickJack Portable Car Jack 40 P/N 5900959 — Rev. H — May 2018
Frames at Full Height with No Load
The issue is that the QuickJack is designed and engineered to work with the weight of a Vehicle on it.
When there is no weight at full height, the QuickJack Frames can get stuck.
Methods that have fixed this issue include:
• Use lifting equipment to get weight onto the QuickJack Frames.
• Reduce the hydraulic force that is holding the QuickJack Frames. If you do this, keep a rag handy
in case there is some Hydraulic Fluid leakage.
If you are still unable to lower the frames, contact QuickJack Technical Support for assistance.
Vehicle with No Tires Fully Lowered
The issue is that there is too much weight on the QuickJack frames with no room to get upward force
started. You need to reduce the weight by about half or raise the Vehicle off the frame a different way.
Methods that have fixed this issue include:
• Use a floor jack to raise the Vehicle from four to six inches.
• Using lifting equipment to raise the Vehicle.
If you are still unable to raise your Vehicle, contact QuickJack Technical Support for assistance.
Priming the Pump
Priming the pump pushes Hydraulic Fluid into the system. On rare occasions, there may not be
enough Hydraulic Fluid in the system for the pump to produce force. Priming the pump usually
resolves this issue.
Note: If your Power Unit does not have a relief valve, you cannot prime it.
To prime the pump:
1. On the Power Unit, remove the relief valve, then place a rag over the cavity and hold it there.
2. Press Up on the Pendant Control for a few seconds (until you feel pressure on the rag).
3. Reinstall the relief valve.
The pump should now have enough Hydraulic Fluid to operate normally.
