OPERATION
PREPARING THE MOWING AREA
Lawn Surface
1. The lawn surface should be as uniform as possible. Bare patches and leaves can disrupt the
operation of the mower. Clear leaves at regular intervals and repair dead patches with grass seed
2. Inspect the lawn for holes or hollows. Fill them with topsoil to prevent rainwater from forming pools
of water on the lawn and to prevent mower from becoming stuck. The mower may be damaged if it
is operated in pools of water (Fig. 5).
3. If there are stones on the lawn that may damage the mower, they should be removed or excluded
from the working area (Fig. 6).
NOTE: This mower is not designed to cut excessively long or overgrown and neglected areas. For
best performance mow or trim grass down to 2.36'' (60 mm) before use. Do not allow grass to grow
excessively long between uses.
DEFINING THE MOWING AREA
Lawn edges must be clearly defined by flat edging or raised barriers in order for this mower to function
properly.
1. Visual boundaries need to look different from lawn, therefore changes in color and texture are very
effective.
2. Physical boundaries help stop the mower, when a visual boundary is not possible.
3. Temporary physical boundaries can be used while the lawn boundary definition is improved.
The robotic mower is equipped with the following devices which allow it to detect the edges and know
where to mow:
•
The lawn detection camera: for recognizing changes in surface type, e.g., from lawn to paving.
•
Two ultrasonic object sensors: for detecting the obstacles higher than 9.84'' (25 cm). They are
turned on by default setting and will sense plants, shrubs and other obstacles in and around
the edges of the lawn. For a consistent cut, long grass must be cut down before mowing, or the
ultrasonic sensors must be turned off.
The ultrasonic sensors can be turned off when the lawn to be mowed is clear of obstacles. In this case,
hedges, walls, or other similar barriers in the lawn can be used as the border of the working area.
When the robotic mower detects that there is no lawn or encounters an obstacle, it changes route in
a random manner and starts mowing again in a new direction. To allow the robotic mower to move
freely inside the lawn, the lawn must be properly checked and adjusted so that the robotic mower has
enough space for recognizing when there is no grass. Carefully follow instructions listed as below for
types of borders/protections that can/cannot be used for defining the working area.
