5. Check the clear zone after running the engine for 30
seconds.
If the indicator is in the red area, replace the
filter.
If the indicator is in the clear area, the filter is
OK.
6. Shut off the engine.
Charging System
On machines with Continental, Cummins, Ford or Hatz
engines, when the engine is running, the ammeter needle
(refer to Figure 7.6) should be to the right of “0.” Left of
the “0” is discharging.
On machines with General Motors engines, when the en-
gine is running, the voltmeter (refer to Figure 7.6) should
indicate between 12.5 and 14 volts.
Cold Weather Start Kit
If the machine is equipped with an optional engine block
heater, radiator hose in-line heater, visually inspect the
heater and power cord. Inspect for leaks around the
heater and for damage to the power cord.
Electrical System
Electrical power is supplied from a 550 CCA, 12 V bat-
tery. The battery is behind the door on the left side of
the turntable (refer to Figure 7.7). The battery supplies
12 V DC electrical power to operate the aerial platform
electrical and electrohydraulic components, including the
emergency power system.

Warning
Batteries give off hydrogen and oxygen that can
combine explosively. Death or serious injury could
result from a chemical explosion. Do not smoke or
permit open flames or sparks when checking the
batteries.

2. Remove the fuel line from the tank using the quick
disconnect fitting.
3. Pull on each latch to release the straps from the tank
(refer to Figure 7.4).
4. Carefully lift the tank from the cradle.
5. Latch both straps to secure the tank.
6. Connect the fuel line and open the shutoff valve.
Fuel Line
To inspect the fuel line:
1. Visually inspect the entire length of the fuel line start-
ing at the fuel tank.
2. Trace the line to the engine, inspecting for leaks and
damage.
Air Filter
The air filter gauge (refer to Figure 7.6) has an indicator
to show when the filter needs replaced.

Note
This inspection does not apply to machines equipped with
a Hatz engine. Hatz engines do not have an air filter that
is accessible to the operator.
To inspect the air filter:
1. Turn the battery disconnect switch on and close the
cowling door.
2. On dual fuel machines, set the fuel switch to either
LPG or gasoline.
3. At the lower controls, place the emergency stop
switch in the on position.
4. Insert the key into the start switch and turn the engine
on.
