Functional description

Moving on the grass surface
The appliance moves freely in a mowing area de-
limited by a boundary cable. The appliance is ori-
ented by sensors that detect the magnetic field of
the boundary cable.
If the appliance encounters an obstacle, it stops
and then continues in another direction. If the ap-
pliance detects moisture, it automatically returns
to the charging station. If the appliance gets into
a situation where it cannot operate, this is indicat-
ed by a message on the display.
Mowing and charging
The mowing phases alternate constantly with the
charging phases. If the charge of the recharge-
able battery drops to a specific value (display:
0 %) during mowing, the appliance returns to the
charging station along the boundary cable.
Pre-set mowing programs are available for mow-
ing, and also include the lawn and edge mowing
function. These mowing programs can be
changed.
Each time the mowing motor is started, its direc-
tion of rotation is changed which doubles the ser-
vice life of the cutting blades.
