QuickJack Portable Car Jack 36 P/N 5900959 — Rev. H — May 2018
Additional Operating Information
Keep the following in mind when operating your QuickJack:
• Use it only on a hard, flat surface. Your QuickJack is portable; if you move it to a new location,
make sure the new location has a hard, flat surface.
• Check the weight of a Vehicle before attempting to lift it. Do not guess. Never exceed the rated
load capacity of your QuickJack.
• Always use Lift Blocks. Do not raise a load on the QuickJack Frames alone.
• Lift Blocks must only be used in the Receiver Trays. Note that the provided Lift Blocks are
not
designed for use with unibody/pinch weld frames. If you have a Vehicle with a unibody/pinch-weld
frame, QuickJack recommends ordering optional Pinch-Weld Blocks, available on the
QuickJack website.
• If you purchased the SUV and Light Truck Adapter kit, the square pieces go rubber-down in the
Receiver Trays on the QuickJack Frames. You can then put the round stackable adapter in the
hole on the top of the square piece either by itself or combined with the extension.
• Visually inspect your QuickJack before each use. Do not use it if you find any damage or severe
wear.
• Do not rock the Vehicle while it is raised or remove heavy items that could cause excessive weight
shift.
• The QuickJack uses a parallelogram lifting system. As the Frames rise, both the mechanical forces
of the jack and pressure of the hydraulic system are reduced significantly as the parallel arms
elevate through the rise motion.
• When the parallel lifting arms are elevated (the angles increase), hydraulic system pressure is
reduced and mechanical load on the structure is minimized.
• Raising the QuickJack to the Top Locking Position and engaging it there is the most secure
method of support.
• When the parallel lifting arms are almost horizontal with the floor, both mechanical loading and
hydraulic system pressures reach maximum loading.
• Stopping the QuickJack prior to reaching the First Locking Position makes it difficult for the
hydraulic system to maintain equal pressure and properly support the load, as the parallel lifting
arms are almost horizontal with the ground.
• Do not stop raising the QuickJack Frames until you have passed the First Locking Position.
• Never leave a raised load unless your QuickJack is engaged on a locking position or on the
ground.
