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. Ensure the service brake pedal is depressed, parking
brake is set and the transmission is in neutral.
NOTE: The engine will not crank unless the service brake
pedal is depressed and the transmission shift lever
is in neutral.
2. 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.
3. 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.
4. Immediately check the engine instruments for proper
indications after starting. Shut down the engine if the oil
pressure warning light remains lit for 15 seconds.
5. Allow the engine to warm up at least five minutes before
applying a load. Do not race the engine for a faster
warmup.
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 fast idle for about five
minutes to avoid high internal heat rise and allow for
heat dissipation.
2. Turn the ignition switch to OFF.
Exhaust System Cleaning
The Exhaust System Cleaning Required Indicator (see
page 3-65) is displayed in the warning screen. This indicator
will illuminate when the exhaust system is in need of
cleaning.
When the Exhaust System Cleaning Indicator illuminates or
flashes, start the regeneration process.
The indicator will be lit continuously during the early stages
of required cleaning. If this condition continues, the lamp will
begin to flash and a slight engine derate will occur.
If this condition continues further, the Engine Warning light
will illuminate in addition to the Cleaning indicator and a
severe engine derate will occur.
The only way in which either of these conditions can occur is
if cleaning has been inhibited or a manual cleaning was
interrupted. Refer to Exhaust System Cleaning Switch, page
3-10 for more details on these.
The cleaning process can take place in three different
modes:
Passive: the exhaust is hot enough during normal working
operation to burn off any hydrocarbon (soot) accumulation.
Active: Active cleaning occurs when there is not sufficient
heat in the exhaust to perform the cleaning operation when it
is required. Exhaust temperatures are raised by the system
WARNING
Do not spray starting fluid into the air inlet. The spray will
contact the heater elements and could explode causing
personal injury.
CAUTION
If the temperature indicator does not display proper
reading or the oil pressure light remains on, shut down the
engine and correct the malfunction before resuming
operation.
WARNING
Extreme Heat Hazard!
During the cleaning process the exhaust becomes very
hot. Do not park the vehicle near objects that are
flammable.
Use caution near the exhaust tailpipe as it will also
become very hot.
