Ammeter
The ammeter is located on the gauge panel above the
lower controls (refer to Figure 5.2). The ammeter dis-
plays 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 needle should
be to the right of “0.”
Voltmeter – GM Engines
The voltmeter is located on the gauge panel above the
lower controls (refer to Figure 5.2). The voltmeter displays
battery 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 is located on the gauge panel above
the lower controls (refer to Figure 5.2). The gauge mea-
sures 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
The fuel gauge is located on top of the diesel or gasoline
tank (refer to Figure 5.3). Read the fuel gauge at the line
in the clear plastic window. The gauge indicates the fuel
tank level in fractions of a full tank.

Note
Do not run a diesel fuel tank empty. Air in the fuel line
makes the engine hard to start.
Chapter 5 – Gauges and Displays
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 lower control panel
(refer to Figure 5.1). It measures the accumulated engine
operating time.

Engine Temperature Gauge
The temperature gauge is located on the gauge panel
above the lower controls (refer to Figure 5.2).
Figure 5.2 – Gauge Panel
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.
