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.

Ammeter
On liquid cooled engines it shows the temperature of the
water and antifreeze mixture in the engine block. The
gauge on air cooled engines shows the temperature of
the engine oil as the oil leaves the filter.
Ammeter
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 un-
der normal operating conditions, the ammeter gauge in-
dicator should read "0."
Engine Air Filter Gauge
The air filter gauge (refer to Figure 5.3) is located above
the lower control panel. The gauge measures the air pres-
sure 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
The fuel tank is translucent (refer to Figure 5.4). The amount
of fuel in the tank can be gauged by raising the doors on
the right side of the machine and looking at the tank.
Note
Do not run a diesel fuel tank empty. Air in the fuel line
makes the engine hard to start.
