or aerate the lawn any time later. You can still
adjust the position of the perimeter wire again
during the first few weeks of using the robot
lawn mower. After a certain time, however,
the perimeter wire will become overgrown
with grass and no longer visible. Install the
perimeter wire with a maximum distance of
1 m between fastening pegs (14). Reduce
the distance between the fastening pegs on
uneven areas of the lawn. Avoid situations in
which the wire is not actually on the ground.
Make sure that the perimeter wire cannot be
severed by the robot lawn mower.
•
Installation in the ground
Bury the perimeter wire in the ground at a
depth of up to 5 cm. This will prevent the
perimeter wire (18) getting damaged during
scarifying or aeration, for example.
Important!
Keep a reserve of 1 m of wire at the rear end of
the charging station so that you can make cor-
rections at a later time. Make sure to lay down the
extra length outside of the lawn surface. Do not
cross the wires.
5.5.2 Narrow points
If the lawn has a narrow point, your robot lawn
mower will be able to operate there as long as the
corridor has a width of at least 1.4 m (80 cm bet-
ween the perimeter wires) and a maximum length
of 8 m. (Fig. 3).
5.5.3 Distance to the garden perimeter
When the robot lawn mower approaches a peri-
meter wire (18), the perimeter wire is detected by
the sensors in the front of the robot lawn mower.
Before the robot lawn mower turns about, howe-
ver, it runs over the perimeter wire (18) by up to
30 cm. Please bear this in mind when planning
your mowing area. (Fig. 6a)
5.5.4 Laying the wire in corners
Avoid laying the perimeter wire (18) at a right-
angle (90°) in corners. To make sure that the
robot lawn mower does not run too far beyond the
perimeter wire (18), lay the perimeter wire (18) as
shown in Fig. 6b.
5.5.5 Calculating the gradient of the lawn
The robot lawn mower can cope with gradients
of up to 35%. You therefore need to avoid steeper
gradients. The gradient can be determined on the
basis of the height divided by the distance. (Fig.
6c)

Example: a/b = 35 cm/100 cm = 35%
5.5.6 Installation of the perimeter wire on
gradients
The robot lawn mower can slip on gradients,
especially if the grass is wet, and run over the
perimeter wire (18) as a result. It is therefore
recommendable to pay attention to the following
points (Fig. 6d):
•
In the area at the top of a slope, the perimeter
wire (18) should not be installed on gradients
over 35%. Make sure that a distance of 30 cm
from obstacles and the edges of the lawn is
maintained.
•
In the area at the bottom of a slope, the
perimeter wire (18) should not be installed
on gradients over 17%. Make sure that a dis-
tance of 40 cm from obstacles and the edges
of the lawn is maintained.
5.5.7 Driveways and paved paths
•
Cordon off raised pathways, areas surfaced
with gravel or containing bark mulch, lower
lying beds or other similar areas. Lay the peri-
meter wire (18) at a distance of at least 30 cm
away. (Fig. 6e and 6g)
•
Paths which are flush with the turf do not
need to be cordoned off, because the robot
lawn mower can simply run over them. You
can also lay the perimeter wire (18) over
paths. (Fig. 6f and 6g)
5.5.8 Perimeter islands
To protect obstacles in the mowing area, create
perimeter islands. This will enable collisions with
delicate objects, garden ponds, trees, furniture,
fl ower beds, etc., to be avoided. (Fig. 6h and 6i)
•
Roll out the perimeter wire (18) from the
edges to the objects you want to protect.
•
Secure the perimeter wire (18) with fastening
pegs (14) in a clockwise direction around the
object you want to protect. Be sure to keep a
distance of 30cm with the perimeter wire from
the object to be protected.
•
A distance of minimum 0,8m should be kept
between the island and the external boundary
wire.
•
Completely enclose the perimeter islands and
then run the perimeter wire (18) back to the
point at which you left the edge of the lawn.
•
Perimeter islands need to be at least 0.8 m
apart. Alternatively, combine the objects to
make them into a joint perimeter island. (Fig.
6h)

The perimeter wires (18) to and from the pe-
