Before Starting Engine
Before the engine is started, perform the required
daily maintenance and any other periodic
maintenance that is due. Refer to the Operation and
Maintenance Manual, “Maintenance Interval
Schedule” for more information.
• Do not start the engine or move any of the controls
if there is a “DO NOT OPERATE” warning tag or
similar warning tag attached to the start switch or
to the controls.
• Reset all the shutoffs or alarm components.
• Ensure that any driven equipment has been
disengaged. Minimize electrical loads or remove
any electrical loads.
1. Open the fuel supply valve (if equipped).
2. If the engine has not been started for several
weeks, fuel may have drained from the fuel
system. Also, when fuel filters have been
changed, some air pockets will be trapped in the
engine. In these instances, prime the fuel system.
Refer to the Operation and Maintenance Manual,
“Fuel System - Prime” for more information.
3. If the engine has not been started for more than 3
months, or the engine oil and filter has been
changed, the engine oil system must be primed.
Follow Steps 1 through 5 to prime the engine oil
system.
4. Apply power to the ECM. Ensure keyswitch is
enabled. With the RUN / STOP switch set to the
STOP position, crank the engine for 15 seconds.
Do not start the engine.
5. Turn the keyswitch to the STOP position.
The engine is now ready to run.

Starting the Engine
Normal Engine Starting Procedure
Note: When possible, ensure that the engine is not
started under load.
NOTICE
Do not engage the starting motor when flywheel is
turning.
If the engine fails to start within 15 seconds, release
the starter switch or button and wait one minute to al-
low the starting motor to cool before attempting to
start the engine again.
1. Apply power to the ECM. Ensure keyswitch is
enabled. With the RUN / STOP switch set to the
RUN position, crank the engine. Engine should
start.
2. If the engine does not start , check for any active
fault codes and clear any fault codes that are
present, before attempting to start the engine.
Repeat step 1.
If the engine does not start after 3 attempts, the
ECM will lock out and prevent any further attempts
to start the engine.2.
Note: If the engine fails to start after three attempts,
investigate the cause.
3. After the engine has started follow Steps 3a
through 3d.
a. Check the oil pressure.
b. Inspect the engine for leaks.
c. Ensure that the batteries for the engine are
receiving a charge.
d. After the engine has run for 5 minutes, check
the engine monitoring systems. Ensure that the
engine is operating correctly before the load is
applied.
Adaptive Cylinder Cutout and Cranking
(ACCC)
If a change in the engine noise is noticed with the
engine running, it may be due to the Adaptive
Cylinder Cutout and Cranking (ACCC) configuration.
ACCC is used to control combustion during cold
start, low idle, and low load conditions by only
activating selected cylinders during these conditions.
ACCC helps maintain consistent power and
reduction in white smoke.
