TB42/TB50 – 0074923 21
The aerial platform is equipped with several gauges to
monitor the condition of the machine before and during
operation.
Hour Meter
The hour meter is located on the wiring box on the left
side of the lower controls (refer to Figure 5.1). It mea-
sures the accumulated engine operating time.
Figure 5.1 – Wiring Box
Engine Temperature Gauge
The temperature gauge is located on the lower control
panel (refer to Figure 5.2).
Machines with Kubota engines do not have an engine
temperature gauge.
Figure 5.2 – Lower Controls
The gauge on liquid cooled engines shows the
temperature of the water and antifreeze mixture in
the engine block.
The gauge on air cooled engines shows the temper-
ature of the engine oil as the oil leaves the filter.
Ammeter – Cummins/Deutz/Ford Engines
The ammeter is located on the lower control panel (refer


to Figure 5.2). The ammeter displays the level of current
flow from the alternator to the batteries.
After the engine has been running for a few minutes
under normal operating conditions, the ammeter
gauge indicator should read “0.”
Machines with Kubota engines do not have an engine
ammeter gauge.
Voltmeter – General Motors Engines
The voltmeter is located on the engine gauge panel
above the lower controls. The voltmeter displays bat-
tery voltage.
After the engine has been running for a few minutes
under normal operating condition, the voltmeter
should indicate between 12.5 and 14 volts.
Engine Air Filter Gauge
The air filter gauge (refer to Figure 5.3) is located on the
engine gauge panel above the lower controls.
Figure 5.3 – Air Filter Gauge
The air filter gauge measures the air pressure between
the intake manifold and the air filter.
The yellow indicator disk inside the sight glass stays
at its highest level when the engine is turned off.
When the yellow indicator disk reaches the red area,
it’s time to change the filter element.
After changing the filter, press the reset button to reset
the indicator disk to the bottom of the sight glass.
Fuel Gauge
Access the fuel gauge by opening the door on the right
side of the chassis. Some machines may have a fuel
tank that is translucent. The amount of fuel in the tank
can be gauged by looking at the tank.
Other machines may have a fuel gauge located on top
of the diesel or gasoline tank (refer to Figure 5.4).
