Use the LOW position (i.e. position for clearing hardened snow) only
for clearing hardened snow. Do not set the auger housing in this
position while clearing soft snow or clearing on a bumpy road. This
can damage the road surface or cause stones to be thrown out of the
auger, which is very dangerous. Also, it can cause excessive wear and
damage to the snow clearing part of the snowblower.
When the mode selector switch is in AUTO or POWER, the auger
housing automatically rises while going in reverse.
In case the auger clutch switch is in the ON position, the auger is
automatically returned to the original position when the
snowblower is transporting forward again.
If you want to stop the automatic movement of the auger housing,
change the mode selector switch to the ''SELF'' position.
To stop the automatically movement of the auger housing, push the
control switch once to the opposite direction of the movement.
Frequent operation of the auger housing control switch activates the
protection function and makes the drive control warning indicator
(orange) blink, which prevents you from adjusting the snow clearing
part of the snowblower. Stop operating the auger housing control
switch and wait a few seconds before operating the switch again.
