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 operation
Do not use volatile starting aids such as ether, propane or
gasoline in the engine air intake system. Glow plugs may ignite
vapors which can cause engine damage or personal injury.
In order to operate the engine in temperatures of 0°C (32°F) or lower,
read the following instructions:
• Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they're in
optimum condition.
• Use a permanent-type engine coolant solution to protect the engine
against damage from freezing.
