OVER-REVOLUTION CAUTION SYSTEM

CONDITION:
The CDI unit controlled over revolution limiter will engage at the engine speeds shown below.
Once engaged it will initiate an intermittent ignition signal to reduce engine speed.
Over revolution limiter: 6 500 r/min
ACTION:
• If the operator decreases engine speed to less than approximately 6 200 r/min within 10 seconds, the
over-revolution caution control will be cancelled.
• If the engine is operated at a speed above 6 500 r/min for more than 10 seconds, the engine speed will be
automatically lowered to approximately 3 000 r/min by intermittent ignition.
• During operation of the over-revolution caution control, the caution lamp is ON.
RESET:
To cancel the over-revolution caution control, close the throttle to reduce the engine speed below approxi-
mately 2 500 r/min for more than one second.
NOTE:
In neutral gear, the preset maximum engine speed value before
the over-revolution caution system activates is 4 000 r/min.
In the operation of Neutral gear over-revolution caution system,
the lamp does not light.
To cancel the Neutral gear over-revolution caution control, close
throttle completely for more than one second.
