Special QuickJack Warnings
There are two special cases with QuickJack of which you need to be aware:
• Do not raise QuickJack Frames without a Vehicle on them. QuickJack Frames are
designed and engineered to be used with the weight of a Vehicle on them. You should only raise
the QuickJack Frames with the weight of a Vehicle on them, even the very first time you use
them. The only exception to this rule is if you are bleeding the Hydraulic Cylinders.
QuickJack Frames can occasionally get stuck in a raised position if you raise them without the
weight of a Vehicle. There is nothing wrong with them if this happens, and the issue can be quickly
and easily fixed, it is just that they are designed and engineered to work with the weight of a
Vehicle. Only raise your QuickJack Frames with a Vehicle on them.
• Do not try to raise a load at no net rise. The QuickJack cannot raise a full load from a
completely flat starting position, as shown below. Your QuickJack requires some space between
the ground and your Vehicle to build up enough pressure to raise a load.
This is not a problem in normal operation, as the Vehicles you want to raise are being held well
above the ground by their tires. The problem happens if you lower the QuickJack to a completely
flat position when the Vehicle's tires are removed.
⚠
WARNING
QuickJack™ Portable Car Jack
This image shows the QuickJack Frames at a completely flat position holding a
Vehicle with no tires. Do not do this; the QuickJack will not be able to raise the
weight of the Vehicle under these circumstances. If this happens to you, refer to
Troubleshooting, visit quickjack.com/support, or send email to
support@quickjack.com for instructions.
