Frames at Full Height with No Load
The QuickJack is designed and engineered to work with the weight of a Vehicle on it. If there is no
Vehicle on the Frames at full height, the QuickJack can occasionally get stuck.
Do not raise the QuickJack Frames unless there is the weight of a Vehicle on them.
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 develop the
upward force required. You need to reduce the weight by at least half or raise the Vehicle off the
QuickJack Frames using a different method.
Methods that have resolved 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 at
support@quickjack.com, or call (888) 262-3880 or (805) 933-9970.
QuickJack™ Portable Car Jack
Action to Take
Pressure is building up in the hydraulic system. To release it, hold
Down on the Pendant Control for ≈5 seconds after the Frames
reach the ground, allowing as much Hydraulic Fluid as possible to
return to the Fluid Reservoir.
There is not enough Hydraulic Fluid in the reservoir. Return the
QuickJack Frames to the ground, then add fluid to the reservoir to
.5 inch below the fill port.
