flammable and highly explosive. A fire or
explosion from fuel can burn you and others
and can damage property.

LED status light illuminates. The MIL is the red light
located on the right side of the hour meter.
Once the light illuminates, make initial troubleshooting
checks; refer to the LED status light section under
Troubleshooting (page
If these checks do not correct the problem, further
diagnosis and servicing by an Authorized Service
Dealer is necessary.
