7.8.11 ENGINE SPEED
The maximum and idle engine speeds are
factory-set to the specifications. See Section
4.2 SPECIFICATIONS. If specified speeds
cannot be maintained, see your Dealer.
IMPORTANT
Do not remove any seals from injector
pump; removal of seals will
void the
engine warranty
.
See also Section 6.3.5.2 Engine Intermediate
Speed Control (ISC).
7.8.11.1 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 the slow
speed stop and the full RPM stop without
contacting the console at either position.
If the throttle lever is contacting the console and
interferes with specified engine speeds, the
sensor position possibly requires adjustment.
See your Windrower Dealer.
