OPERATION

3. Clean the area around filler cap (A).

4. Turn cap handle (B) counterclockwise until loose and

then remove cap.

5. Fill tank with approved fuel. Refer to

Lubricants, Fluids,

and System Capacities, page 263

.

IMPORTANT:

Do NOT fill tank completely—space is required
for expansion.

A filled tank could overflow

if exposed to a rise in temperature, such as
direct sunlight.

6. Replace fuel tank cap (A) and turn cap handle (B)

clockwise until snug.

Engine Temperature

The normal engine operating temperature range is
180–225°F (82–107°C) and is indicated by the temperature
gauge (B) on the operator’s console.

If the temperature exceeds 230°F (110°C), an ongoing
intermittent tone will be heard and the cab display module
(CDM) will flash “ENGINE TEMP”.

Stop the engine

immediately

and determine cause. The tone will stop and

the CDM will return to normal when the temperature drops
below 225°F (107°C).

Figure 4.13: Operator Console

Engine Oil Pressure

The nominal engine oil pressure is 10 psi (69 kPa) at low idle and 55.1 psi (380 kPa) at maximum rated speed.

If the oil pressure drops below the preset level of 7.5 psi (52 kPa), the cab display module (CDM) flashes an error
code and error message.

If the STOP ENGINE light illuminates, stop the engine IMMEDIATELY and investigate.

If the yellow CAUTION light illuminates, stopping immediately is optional. You may continue operations and
investigate later, but you are STRONGLY advised to monitor the situation carefully.
