Engine Starting
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, the engine oil system must be primed.
Follow Steps 3.a through 3.b to prime the engine
oil system.
a. Ensure that the governor stays in the STOP
position by disconnecting the speed pickup
connector on the governor control.
b. Turn the keyswitch to the START position. Hold
the keyswitch in this position until the oil
pressure gauge indicates 100 kPa
(14.5040 psi). Continue to hold the keyswitch in
the START position for an extra 10 seconds.
Only crank the engine for 30 seconds when
building engine oil pressure. After 30 seconds,
stop cranking and allow 2 minutes for the
starter to cool.
Note: The keyswitch is part of the OEM supplied
panel. The exact procedure for starting may vary.
Refer to OEM supplied instructions for the correct
starting procedure.
4. Turn the keyswitch to the STOP position.
Reconnect the speed pickup connector.
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.
1. Turn the keyswitch to the START position. The
engine should start immediately.
2. Allow the keyswitch to return to the RUN position
after the engine starts.
If the engine does not start after 10 seconds,
return the keyswitch in the RUN position for 10
seconds. Then repeat Steps 1 and 2.
Note: If the engine fails to start after three attempts,
investigate the cause.
3. After the engine has started follow Steps 3.a
through 3.d.
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.
Cold Weather Starting
Do not use aerosol types of starting aids such as
ether. Such use could result in an explosion and
personal injury.
Startability will be improved at temperatures below
+10 °C (+50 °F) from the use of a jacket water heater
or extra battery capacity.
