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, or the engine oil and filter has been
changed the engine oil system must be primed.
Follow Steps 3a through 3b 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 a maximum of 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.
