Transmission Neutral Indicator Light
Light (NEUTRAL) is on when transmission is in neutral.

Low Air Warning Light
Warning light (LOW AIR) comes on when air pressure in one or
both airbrake system reservoirs drops below 65 psi (448 kPa).
Warning light comes on at engine startup and remains on until a
minimum of 65 psi (448 kPa) in airbrake system is reached.
38
Parking Brake Indicator Light
Light (PARK BRAKE) comes on when parking brake is activated.

Coolant Temperature Gauge
Normal safe operating range is in green area on gauge. Typical
temperature range is 190-215F (88-102C). Higher temperatures
may occur intermittently under certain conditions.
40
Engine Oil Pressure Gauge
Typical oil pressure at rated speed is 35-70 psi (240-480 kPa). If
oil pressure drops below 5 psi (35 kPa), HIGH WATER LOW OIL
warning light and alarm will come on.

Indicates rate of battery charge or discharge in volts:
Pointer in GREEN area on gauge shows normal battery
condition (13.5-14.0V).
Pointer in upper (RED) area indicates overcharge condition.
In no instance should voltmeter register above 14.5-15.0V.
Pointer in lower (YELLOW or RED) area indicates
undercharge condition. If battery is discharged to any extent,
voltage may read as low as 12.0-13.0V.
When voltmeter shows either an undercharged or overcharged
condition for an extended period, notify maintenance personnel.
