Coolant leaks are easily visible on the ground. Check
under the chassis for coolant that has leaked.
Make sure the radiator core and ventilation openings on
the cover are free of bugs, dirt, or foreign material that
might restrict airflow.
Fuel Tank
Check the fuel level (refer to Figure 7.4) and add fuel if
necessary. Make sure the cap is securely fastened on
gasoline or diesel tanks.
Figure 7.4 – Gasoline or Diesel Tank
Fuel Line
Visually inspect the entire length of the fuel line. Start at
the fuel tank and trace the line (refer to Figure 7.4) to the
engine inspecting for leaks and damage.
Air Filter
The air filter gauge (refer to Figure 7.5) has an indicator
to show when the filter needs replaced.
Figure 7.5 – Air Filter
To inspect the air filter:
1. Turn the battery disconnect switch on and close the
cowling door.
2. At the lower controls, place the emergency stop
switch in the on position.
3. Insert the key into the master switch and turn the
engine on.
4. Check the clear zone after running the engine for 30
seconds.
• If the indicator is red, replace the filter.
• If the indicator is clear, the filter is OK.
5. Shut off the engine.
Charging System
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.

Cold Weather Start Kit—Block Heater
If the machine is equipped with an optional engine block
heater, visually inspect the heater and power cord. In-
spect for leaks around the heater and for damage to the
power cord.
Electrical System
Electrical power is supplied from two, 600 CCA, 12 volt
batteries. These batteries supply 12 volt DC electrical
power to operate the aerial platform electrical and elec-
trohydraulic components.
A
Warning
Batteries give off hydrogen and oxygen that can
combine explosively. Death or serious injury can
result from a chemical explosion. Do not smoke or
permit open flames or sparks when checking the
batteries.
