To inspect the coolant level:
Caution
Engine coolant escaping under pressure may cause
serious burns. Shut the engine off and let it cool
before removing the radiator cap.
1. Shut the engine off and wait for it to cool.
2. Check to make sure the coolant level is between the
Hot and Cold marks on the sight glass
3. If necessary, remove the cap from the coolant reser-
voir and add coolant. Tightly replace the cap.
Note
Refer to Chapter 2 for engine coolant specifications. The
need to regularly add fluid indicates a leak that should
be corrected.
Radiator
To inspect the radiator:
1. Inspect the radiator hoses and clamps for wear, leak-
age, or damage.
2. Make sure the hoses are not hardened, cracked, or
feel spongy.
3. Make sure the cap is in place and tight.
4. Check under the chassis for coolant that has leaked.
Coolant leaks are easily visible on the ground.
5. 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 7.3) and add fuel if
necessary. Make sure the cap is securely fastened.

Note
Refer to Chapter 2 for fuel grade specifications.
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 two 550 CCA, 12 volt
batteries. The batteries are under the engine cover on
the right side of the machine (refer to Figure 7.4). The
batteries supply 12 volt DC electrical power to operate
the aerial platform electrical and electrohydraulic compo-
nents, including the emergency power system.
