4. Allow the engine to warm up at least five minutes before
applying a load. Do not race the engine for a faster warm
up.
Cold Engine
NOTE: The engine ECM monitors the engine and, under
certain conditions, cycles the air heater on and off
at start-up and during operation.
The engine is equipped with an electric air heater grid at the
air inlet elbow to aid in cold starting and reduce white smoke
at start-up. In the preheat mode, the engine should not be
cranked until the Wait-to-Start lamp turns off.
1. Prior to starting a cold engine, ensure the Crane
Function switch is positioned to OFF.
2. Set the parking brake to On, position the transmission
shift lever to neutral, and depress the service brake foot
pedal.
NOTE: The engine will not crank unless the transmission
shift lever is in neutral and the service brake foot
pedal is depressed.
The buzzer will sound upon turning the Ignition
Switch to START and turn off after proper hydraulic
oil pressure is reached.
3. The Wait-to-Start lamp is illuminated during the preheat
time that takes place when the Ignition switch is in the
ON position during cold weather starting. To minimize
cranking time during cold weather starting, the engine
should not be cranked until the Wait-to-Start lamp turns
off.
4. Turn the Ignition switch to START and release
immediately when the engine starts. Do not push or hold
the throttle down. The ECM will automatically provide
the proper amount of fuel to start the engine.
5. Immediately check the engine instruments and warning
lights for proper indication after starting.
6. Allow the engine to warm up at least five minutes before
applying a load. Do not race the engine for a faster warm
up.
Detailed cold weather starting and operating procedures are
covered in the engine manual.
Idling the Engine
Idling the engine unnecessarily for long periods of time
wastes fuel and fouls injector nozzles. Unburned fuel causes
carbon formation, oil dilution, formation of lacquer or gummy
deposits on the valves, pistons, and rings, and rapid
accumulation of sludge in the engine.
NOTE: When prolonged idling is necessary, maintain at
least 800 rpm.
Racing the Engine
NEVER race the engine during the warm-up period. NEVER
operate the engine beyond governed speed (as might occur
in downhill operation or downshifting). Engine bearings,
pistons, and valves may be damaged if these precautions
are not taken.
Shutdown Procedure
1. Allow the engine to operate at idle for about five minutes
to avoid high internal heat rise and allow for heat
dissipation.
2. Turn the Ignition switch to OFF.
CAUTION
Engine Damage Hazard!
If any warning light stays on or indicator(s) do not display
proper readings, shut down the engine and correct the
malfunction before resuming operation.
WARNING
Risk of Explosion!
Do not spray starting fluid into the air inlet. The spray will
contact the heater elements and could explode causing
personal injury.
CAUTION
Avoid Crane Damage!
Do not engage the park brake while the vehicle is moving.
Damage to the crane can occur.
Disengage the park brake before driving. Damage to the
crane can occur.
CAUTION
Engine Damage Hazard!
If any warning light stays on or indicator(s) do not display
proper readings, shut down the engine and correct the
malfunction before resuming operation.
