Pressurizing the Air Cylinders
The Air Cylinders (one on each QuickJack Frame) need to be pressurized before you can use your
QuickJack.
Air Cylinders help push the QuickJack Frames down.
Note that the valve stems on the Air Cylinders are installed at the factory.
Make sure the QuickJack Frames are fully lowered when you pressurize the Air Cylinders.
To pressurize the Air Cylinders:
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 Air Cylinder.
2. Using a pump or air compressor, inflate the Air Cylinder to from 40 to 50 PSI / 2.75 to 3.4 BAR;
do
not exceed 50 PSI / 3.4 BAR
.
The JackPak accessory can also be used to pressurize the Air Cylinders.
3. When the pressure is between 40 and 50 PSI / 2.75 to 3.4 BAR, remove the pump or air
compressor.
⚠ WARNING Do not exceed 50 PSI / 3.4 BAR with the QuickJack Frames in the fully lowered
position, as there is a chance of explosion. Make sure to remove power and bleed
off air pressure before servicing.
4. Repeat Steps 1 through 3 for the other Air Cylinder.
