After the engine starts:
• On some engines, the Wait to
start light should illuminate after
the engine starts. Allow the
engine to idle about three
minutes or until the engine
coolant temperature gauge begins
to rise. Maintain idle speed until the Wait to start light cycles off to
indicate the air intake heater has shut off (approximately six
minutes). Operating the engine at higher speeds will reduce the
effectiveness of the air inlet heater.
• Do not increase engine speed
until the oil pressure gauge
indicates normal pressure.
• Ensure engine oil pressure is
indicated on the gauge within 15
seconds after starting.
• Idle the engine for three to five
minutes before operating with a
full load.
• Try to limit engine idle to 10
minutes. Excessive idling reduces fuel economy.
• When starting a cold engine, increase the engine speed (RPM) slowly
to make sure adequate lubrication is available to the bearings.
Restarting after running out of fuel
The fuel system may need to be purged of air, refer to Running out of
fuel in the Maintenance and specifications chapter.
Cold weather starting
Perform the following to assure efficient starting in cold weather:
• Use the proper grade oil for your climate. Refer to your engine
operator's manual for proper grade oil.
• Test the battery more frequently to assure ample power for starting.
• All electrical connections should be tight and in good condition to
prevent losses through loose or corroded connections.
