Two Safety Cautions about Engine
Fan Breakage
CAUTION:
Changing the Fan Drive Ratio or Engine
Governed Speed
If you change the fan drive ratio or increase the
governed speed of the engine, you may increase
stress on the engine fan and the fan could
eventually fail. If the fan breaks apart while it is
rotating, the flying pieces can cause severe injury
to anyone
--
such as a service technician
--
who is
nearby. And, of course, the pieces can severely
damage the vehicle. Don’t change the fan drive
ratio or increase the governed speed of the
vehicle without getting the necessary information
from your dealer.
CAUTION: (Continued)
CAUTION: (Continued)
Winter Fronts, Grille Covers or Obstructions
Winter fronts, grille covers or other add
-
on
equipment causing obstructions in front or
behind the fan should not be used on this vehicle.
They may increase the stress on the fan as the
blades pass over the covered areas. If this causes
the fan to eventually break apart while it is
rotating, the pieces can cause severe injury to
anyone nearby, such as a service technician
working on the engine, and of course the pieces
can severely damage the vehicle.
