Pneumatic System

The Pneumatic System is used to operate the:
• Air bags
• Chemical pump
• RapidFire system
• Cabin access ladder
• Engage & disengage centre differential
lock on 4WD models.
Pressure Relief Valve
A Pressure Relief Valve incorporated on the
Air Tank tank prevents air pressure within the
system acceptable limits.
The valve is set to open if 150 PSI is reached.
Low Pressure Sensor
A Low Pressure Sensor is fitted to the tank
so that if the air pressure within the tank goes
down to 55 PSI or lower, an alarm will sound
in the cabin to warn the operator.
