Mode selector switch
Use the mode selector switch to change the work mode (automatic
adjustment) of the snowblower. The work mode can be selected from
one of three modes: AUTO, POWER, or SELF.
Characteristics of AUTO mode:
Travel speed is automatically adjusted according to the workload,
which reduces the tendency of snow to pile up in front of the
snowblower.
Engine speed adjustment is not necessary as it is automatically
adjusted according to the operation condition of the snowblower.
The engine speed is automatically adjusted so it is held at the given
speed, which helps to reduce the difference in snow discharge
distance.
The auger is automatically raised when the snowblower is reversing.
In case the auger clutch switch is in the ON position, the auger is
automatically returned to the original position when the
snowblower begins moving forward again.
Forward speed is set low. Select another mode to make the
snowblower travel faster.
