Overspeed Rev Limit

The overspeed rev limit is set at an RPM greater than the
operating range. In the event that the engine is operated at an
RPM greater than or equal to the overspeed limit, the PCM does
not allow the engine to maintain the power required. Refer to
Specifications to determine this engine's RPM limit.
Upon reaching the rev limit, the Guardian System activates the
warning horn. If the operator does not reduce engine speed
within five seconds, the Guardian Systems reduces available
engine power.
To reset the Guardian System protection:
1. Completely reduce throttle for two to three seconds.
2. Reengage the throttle. If the engine does not respond,
repeat step one.
