MASTER SWITCH IN MAIN POWER COMPARTMENT
•
Set the master switch located in the main
power compartment to the
ON position;
•
Make sure the starter selector switch
located in the engine compartment is set to
the
NORMAL position. When starting the
engine from the front of the motorcoach, set
the battery master switch located on the
dashboard to the

Apply the spring-loaded parking brakes by
pulling the parking brake control button all
the way up;
•
Place transmission in neutral;
•
Turn key in ignition to START position,
release after starting.
Caution :
Do not engage starter for more
than 15 seconds at a time. If engine does not
start within 15 seconds, release ignition key and
let starter cool for one minute before attempting
to restart.
Caution :
Do not press accelerator pedal
before starting. This could result in an electronic
control unit fault and degrade the fuel system
control.
Caution :
Special precautions are
necessary with turbocharged engines to avoid
possible turbine damage. After starting, run the
engine at slow idle for two minutes to allow
lubricating oil to reach the turbocharger. Then
run the engine at fast idle. Let oil pressure
reach normal operating range before driving.
Note :
If engine does not start, return key to
OFF position before attempting to restart.
Note :
If the accelerator pedal is depressed
before starting, release and wait 30 seconds
before attempting to restart.

NGINE
•
Apply parking brake and place transmission
in neutral (N);
•
Allow engine to idle for at least two minutes
before shutting
OFF engine. This insures
that the turbine speed drops and allows
time for the engine exhaust gas
temperature to drop to 300 °F (150 °C);
•
Turn key in ignition switch to OFF position.
Caution :
Do not shut OFF engine when
running above slow idle.
Caution :
Set the battery master switch to
the OFF position after parking and when left
unattended for an extended period of time.
Refer to "Controls & Instruments" chapter 3.
