fuel tanks to indicate the engine and transmission oil temperatures, pressures, and fuel levels.
Warning switches. Switches mounted on the engine, transmission, and mechanical transmission indicate, through
gage panel lights, the occurrence of engine oil low pressure and high temperature, transmission oil high temperature,
and mechanical transmission low oil pressure.
Warning indicator lights, gage, and flasher system panel. The panel contains the following components and is located
next to the transmission shift lever bracket, adjacent to the driver's seat:
a. Fire extinguisher engine shutoff light indicates when the fire extinguisher engine shutoff switch is activated.
b. PTO engaged light indicates when the PTO is engaged.
c. Flasher system components include an indicator light, switch, flasher unit, and circuit breaker.
Hydraulic oil temperature gage and indicator light. These components allow the operator to monitor the temperature
of the hydraulic oil during operation of the hydraulic system and warn if a heating problem occurs.
Headlight clusters. The right and left headlight clusters each consist of a service headlight, a B.O. service IR headlight,
a B.O. drive light, and a B.O. marker light. The headlight assemblies are completely interchangeable; however, the
right B.O. drive light is not powered in the B.O. drive condition.
Flasher warning light. A flasher warning light with colored lens is controlled through the flasher unit and switch-
mounted on the shifting lever mounting bracket in the crew compartment.
Dome lights. The dome lights are installed in the crew compartment for interior illumination. The dome light switches
provide for either white or colored light as the tactical situation requires.
High beam indicator light. A high beam indicator light glows red when the vehicle service drive headlights or IR
headlights are changed to high beam through the driver's dimmer switch.
Winch compartment light. The winch compartment light is operated by a switch on the accessories panel and illumi-
nates the hoist winch, main winch, and surrounding areas in the winch compartment.
Rigger's fixed spotlight. The rigger's fixed spotlight is controlled by a handle that extends through the roof into the
rigger's area in the crew compartment.
Rigger's service light assembly. The rigger's service light assembly, controlled by the rigger's light selector switch,
projects a high beam.
Rigger's B.O. light. The rigger's B.O. light is controlled by the rigger's light selector switch and projects a high beam.
Taillight assemblies. The right taillight assembly consists of the B.O. marker taillight. The left taillight assembly
consists of the service taillight, service stoplight, and B.O. marker light.
