of the following to happen:
a.

seconds, the light will go out, indicating

continue holding the START switch
to GLOW. After about 15-20 seconds,
depending on the outside temperature,
the glow plug light should come on.
That means the glow plug is warm
enough for startup.

START switch clockwise to the START
position and hold for 15 seconds or
until the APU starts.
If the APU ±res but does not start, turn

If the APU doesn’t start after four attempts,
call in your mechanic.
