MANUAL mode:
When the workload increases while clearing the snow, the engine speed and
snow discharge distance drop below the given speed and distance that have
been set with the throttle control lever. Reduce the workload applied to the
snow clearing part of the snow blower to hold the engine speed/snow discharge
distance at the given speed/distance. If you are not sure of the appropriate
position to set the engine speed and snow discharge distance, we recommend
that you set the throttle control lever in the third position from the bottom
(maximum power position). Then, adjust the snow discharge distance at the
desired position while you are clearing the snow.
