Boundaries Within the Working Area
Use the boundary wire to demarcate areas inside the
working area by creating islands around obstacles which
can not withstand a collision, for example flowerbeds,
bushes and fountains. Lay the wire up to and around
the area to be demarcated, and then return it back along
the same route. If pegs are used, the wire should be
laid under the same peg on the return route. When the
boundary wires to and from the island are laid close
together, the robotic lawnmower can drive over the wire.
IMPORTANT INFORMATION
The boundary wire may not be crossed on
its way to and from an island.
Obstacles that can withstand a collision, for example
trees and bushes higher than 15 cm, do not need to be
demarcated by the boundary wire. The robotic lawnmower
will turn when it collides with this type of obstacle.
It is recommended to isolate all fixed objects in and
around the working area. This results in the most gentle
and silent operation and prevent the robotic lawnmower
from getting stuck in the objects under any circumstances.
Obstacles that slope slightly, for example stones or large
trees with raised roots, must be isolated or removed.
Otherwise the robotic lawnmower can slide up onto this
kind of obstacle causing the blades to be damaged.
Secondary Areas
If the working area consists of two areas which the
robotic lawnmower has difficulty traveling between, it is
recommended to set up a secondary area. Instances of
this are 45 % slopes or a passage that is narrower than
60 cm. Then lay the boundary wire around the secondary
area so that it forms an island outside the main area.
The robotic lawnmower must be moved manually between
the main and secondary area when the lawn in the
secondary area has to be cut. Since the robotic lawnmower
is not able to get to the charging station by itself from a
secondary area, Secondary area (A) operating mode must
be used, see 5.1 Operating Mode Start on page 38.
The robotic lawnmower will then not start searching for the
charging station but use its entire capacity to mow. When
the battery is flat, the robotic lawnmower will stop and the
Needs manual charging message will appear in the display.
Then place the robotic lawnmower in the charging station
to charge the battery. If the main area is to be cut straight
after charging, the START button must be pressed and the
Main area (A) selected before closing the hatch.
