onds, the over-revolution caution control will
be
cancelled.
• If the engine
is
operated at a speed above 6500
RPM
for more than
10
seconds, the engine
speed will
be
automatically lowered to approxi-
mately
300
RPM
by intermittent ignition.

control, the caution lamp
is
ON.

close the throttle to reduce engine speed below
approximately
2500
RPM
for more than one sec-
ond.
