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.
4. Carefully lift the tank from the cradle.
5. Place a full tank in the cradle making sure the slot in
the tank aligns with the pin.
6. Latch both straps to secure the tank.
7. 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.
Electrical System
Electrical power is supplied from a 600 CCA, 12 volt bat-
tery. The battery is under the engine cover on the left side
of the engine (refer to Figure 7.6). The battery supplies
12 volt 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.
Caution
Even with low voltage electrical systems, severe
arcing may occur. Electrical shock or component
damage may result from contact with energized
conductors. Use caution when working with any
electrical device.
The battery is automatically charged when the engine is
running. Include the battery when inspecting and servicing
the electrical system.
For optimal battery performance the battery fluid level
must be maintained and the battery connections must
be kept clean.
Battery Fluid Level
To inspect the battery fluid level:
1. Remove the caps from the battery (refer to Figure
7.6).
2. Visually check the battery fluid level making sure the
level is within
1
/4″ (6 mm) of the bottom of the filler
neck inside each hole.
3. If necessary, add distilled water.
Note
Use only distilled water when refilling the battery. Tap
water may contain metallic solids such as iron which can
reduce the life of the battery.
4. Replace the caps on the battery. The caps must be
in place and tight during machine operation.
Battery Terminals
To inspect the battery terminals:
1. Check the top of the battery, the terminals, and cable
ends. They should be clean and free of corrosion
(refer to Figure 7.6).
2. If necessary, clean the top of the batteries. Clean the
terminals and cable ends with a wire brush or terminal
cleaning tool.
3. Make sure all cable ends are securely fastened to
the terminals.
Cables and Wiring Harness
To inspect the cables and wiring harnesses:
1. Visually inspect all cables and wiring for wear and/or
physical damage such as loose connections, broken
wires, and frayed insulation.
2. Check the wiring in areas where a change in routing
direction may cause them to become pinched.
3. Make sure the cables and wires are properly routed
to avoid sharp edges, pinching, and scuffing.
