CLUTCH
2E331
The clutch may require tuning depending
upon the area of operation and desired han-
dling characteristics. The clutch can be
tuned by changing engagement and shifting
speed. Clutch engagement speed is defined
as the engine speed where the machine first
begins to move from a complete stop.
Shifting speed is when the machine has
been started at full-throttle from a dead stop
and has travelled 200 X 300 m (650 X 1,000
ft).
Normally, when a machine reaches shifting
speed, the vehicle speed increases but the
engine speed remains nearly constant. Un-
der unfavorable conditions (wet snow, icy
snow, hills, or rough terrain), however, en-
gine speed may decrease after the shifting
speed has been reached.
