Controls and Instruments
1. Tachometer/Hour Meter indicates engine
rpm (normal idle 800 rpm; governed 2,950 rpm)
and operating hours of engine (Figure 4-2).
2. Dash Lights illuminate dash panel and side
sloping dash panel (Figure 4-3).
3. Rear Axle Centering Indicator light is off
when axle is centered with wheels parallel to line
of travel for two-wheel steering. Light is on
when wheels are off center. When light is off,
switch to two-wheel steering (Figure 4-2).
4. Horn is activated when pushed, and is deacti-
vated when blackout lighting is used.
5. Engine Water Temperature Gauge indicates
engine coolant temperature (temperature range is
140 to 220 degrees F [60 to 104 degrees C];
approximately 190 degrees F [88 degrees C] is
normal operating temperature).
6. Engine Oil Pressure Gauge indicates engine
oil pressure (idle of 10 psi [69 kpa] minimum to
governed speed no load of 55 psi [379 kPa]; cold
oil may read 90 psi [621 kPa]).
7. Fuel Gauge indicates amount of fuel in fuel
tank.

8. Cold Start is recommended for ambient tem-
peratures below 32 degrees F (O degrees C ) and
required at 10 degrees F (-12 degrees C) and
below.
9. Transmission Temperature Gauge indicates
oil temperature out of convertor (normal range is
160 to 190 degrees F [71 to 88 degrees C]; cool
down is required above 250 degrees F[121
degrees C]).
10. Voltmeter indicates battery condition (24
volts is normal indication).
