Engine Speed
The maximum and idle engine speeds are factory set.
Refer to
2.2 Specifications, page 31
for detailed information. If speci
fi
ed speeds cannot be maintained, see your
MacDon Dealer.
Refer to
Engine Intermediate Speed Control (ISC), page 163

Throttle Adjustment
The engine speed is controlled with the throttle lever that is connected to an electronic sensor inside the console.
The throttle lever in the cab should move the throttle sensor the full range between slow speed stop and full rpm
stop without contacting the console at either position.
If the throttle lever is contacting the console and interferes with speci
fi
ed engine speeds, the sensor position may
need adjustment. See your MacDon Dealer.
