Your QuickJack requires a little bit of space to get going to raise a load. It cannot raise a full load from a completely flat starting position. 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
