per hour (mph), or with optional speedometer, it may
indicate truck speed in kilometers per hour (kph). The
display also shows payload meter information. For
more information, see Payload Meter in index.
Voltmeter
Voltmeter (19) indicates the volt-
age of the 24v battery system.
Normal indicated voltage at high
rpm is 27 to 28 volts with batter-
ies in the fully charged condition.
When keys witch (10) is ON and
the engine is not on, the voltme-
ter indicates battery charge condition.

Engine Oil Pressure Gauge

Engine oil pressure gauge (20) indicates pressure in
the engine lubrication system in pounds per square
inch (psi). Normal operating pressure after engine
warm up should be:
Idle - 138 - 250 kPa (20 to 35 psi)
Water Temperature Gauge
Water temperature gauge (21)
indicates the temperature of the
coolant in the engine cooling
system. The temperature range
after engine warm-up and the
truck operating under normal
conditions should be:
Fuel Gauge
Fuel gauge (22) indicates how
much fuel is in the fuel tank.
