INSP 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.
INSP GEAR SELECTION 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 unfavorable snow conditions, drive/driven gear ratio should be increased. If the surfaces are fairly smooth or better snow conditions exist, decrease the ratio.
