To pressurize the Pneumatic Springs:
1. Use a valve tool to release a short hiss of air to check the air inflation valve for proper operation and
to drain any accumulated oil.
Holding the valve open, releases the air currently in the Pneumatic Spring.
2. Using a pump or air compressor, pressurize the Pneumatic Spring to 40 - 50 psi / 2.75 - 3.4 bar;
do not exceed 50 psi / 3.4 BAR.

Tip
QuickJack™ Portable Car Jack
Avoid severe injury or death from explosion. Maximum air pressure on the
Pneumatic Spring should never exceed 50 psi / 3.4 bar with the QuickJack frames
in their fully lowered position. Lock-out power and bleed off air pressure before
servicing.
Make sure the QuickJack Frames are fully lowered when you pressurize the
Pneumatic Springs.
may also be used to pressurize the Pneumatic Springs.
Do not exceed 50 psi / 3.4 BAR with the QuickJack Frames fully lowered.
The Hydraulic Cylinder Seals may become dry and stiff during transit allowing air to leak
from the top of the cylinder around the piston rod. Place a few drops of Hydraulic Fluid
on top of the Hydraulic Cylinders where the piston rod exits the Cylinder. This condition
will improve as the seal is lubricated and regains its elasticity during operation. If it
continues to leak refer to Troubleshooting .
