Clearing snow
For the best efficiency, clear snow before it melts, freezes and hardens.
Select appropriate speed with the main shift lever, and do not reduce
engine speed while throwing snow. When the ICS (Intelligence Control
System) is off, observe the following if the engine speed is reduced
with the main shift lever set in LOW.
Clearing in narrow width
Clear snow in LOW and in narrow width by using part of the snow
blowing mechanism when the snow is deep or hard.
Clearing with back and forth motions
If the snow is so hard that the snowblower tends to ride over the sur-
face, push it back and forth to remove snow gradually.
When the ICS switch is on, the auger housing automatically rises
during reversing.
