2008 FORD F750 headlamp

Note:When starting the engine, do not press the accelerator as engine
damage may result.
1. Ensure headlamps and all accessories are turned off, the parking
brake is applied and the transmission is in the neutral position (or P
[Park] for Allison 2200 transmissions).
2. Turn the key to ON, but do not start the engine. In cooler weather,
the air intake heater may activate the WAIT TO START light in the
instrument cluster.
If the WAIT TO START light
illuminates,do notcrank the engine
until the light goes off.
If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could cause an explosion
and result in property damage and/or personal injury.
3. When the WAIT TO START light turns off, turn the key to START;
when the engine starts, release the key.
If the engine does not start after 30 seconds of cranking, allow two
minutes for the starter to cool before trying again. Excessive cranking
may damage the starter.
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.
