controls the engine speed.
•
When the overheat
warning or low oil pres-
sure warning is acti-
vated, the DES switch is
turned on and the warn-
ing buzzer is activated.
•
When this occurs, the

is cut off, and the engine
speed decreases to less
than 2,000 r/min.

controls the engine speed.
Two cylinders misfire and
