6) Power Systems
A) Air
i) Air Pressure
PROCEDURES/SPECIFICATIONS:
With air system fully charged (compressor governor
				"cut-out") run engine at low idle. Make one full (maximum) brake application
				and immediately record reservoir air pressure.
Apply and release brakes until pressure indicated on
				the air gauge is at least 10 psi (i.e., pounds per square inch) below governor
				"cut-in" pressure. Run engine at high idle and determine seconds required to
				raise reservoir pressure from recorded pressure.
REJECT VEHICLE IF:
Time required to raise air pressure from recorded to
				cut-out is more than 30 seconds. Air gauge is missing or does not
				operate.
ii) Low Pressure Warning Device
PROCEDURES/SPECIFICATIONS:
Complete the following steps to evaluate low
				pressure warning device.
1) Before starting the engine, apply brakes and
				release until low air pressure warning device functions.
2) Start the engine.
3) Apply service brakes and release until air
				compressor is activated.
4) Continue to run engine until compressor cut-out
				pressure is reached.
5) Record compressor cut-out pressure.
6) Shut engine off.
Determine if low pressure warning device is missing
				or inoperative.
If located in the driver's forward field of view,
				the warning device can be a visual device only. If not located in the driver's
				front view, the device must be both audible and visible.
Record the reading found on the pressure gauge at
				which the low pressure warning device functions.
