CLUTCH/GEAR SELECTION
The clutch may require tuning depending upon where
the machine will be operated and the desired han-
dling characteristics. The clutch can be tuned by
changing the engagement and shifting speeds.
Clutch engagement speed is defined as the engine
speed at which the machine first begins to move from
a complete stop.
Clutch shifting speed is defined as the engine speed
reached when the machine has travelled 200 ~
300 m (650 ~ 1,000 ft) after being started at full-
throttle from a dead stop.
Normally, when a machine reaches shifting speed,
the vehicle speed increases but the engine speed
remains nearly constant. Under unfavorable condi-
tions (wet snow, icy snow, hills, or rough terrain),
however, engine speed may decrease after the shift-
ing speed has been reached.

GEAR SELECTION
The reduction ratio of the driven gear to the drive gear
must be set according to the snow conditions. If there
are many rough surfaces or unfavorable snow condi-
tions, the drive/driven gear ratio should be increased.
If the surfaces are fairly smooth or better snow
conditions exist, decrease the ratio.
Gear ratio chart
The drive and driven gears and the chains shown in
the gear ratio chart are available as options. The
figures containing a decimal point represent the drive/
driven gear ratios, while the bottom numbers desig-
nate the number of links in the chain.
