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. For buses manufactured before September 1, 1974, the device can be either audible or visible.
