3.5.1 Plan where to lay the boundary wire
The boundary wire must be laid so that:
• The wire forms a loop around the working area. Use
original boundary wire. It is specially designed to
resist dampness from the soil.
• The robotic lawnmower is never more than 15 m / 49
ft. from the wire at any point in the working area.
• The wire is no more than 400 m / 1312 ft. long.
• About 20 cm / 8 in. of extra wire is available to which
the guide wire will be connected later. See
the boundary wire on page 18 .
The illustration below shows how the boundary wire
must be laid around the working area and around
obstacles. Use the supplied measurement gauge to
obtain the correct distance. See
page 6 .

3.5.2 Working area boundaries
Depending on what the working area is adjacent to, the
boundary wire must be laid at different distances from
obstacles.
If a high obstacle (5 cm / 2 in. or more), for example a
wall or fence, borders the working area, the boundary
wire should be laid 30 cm / 12 in. from the obstacle. This
will prevent the robotic lawnmower from colliding with
the obstacle and reduce body wear. About 20 cm / 8 in.
of the lawn around the fixed obstacle will not be mown.

If the working area borders a small ditch, a flower bed or
a small elevation, for example a low kerbstone (1-5 cm /
0.4-2 in.), the boundary wire should be laid 20 cm / 8 in.
inside the working area. This prevents the wheels from
driving into the ditch or up onto the kerbstone which
might be lead to excessive wear on the robotic
lawnmower. About 12 cm / 5 in. of the lawn along the
ditch/kerbstone will not be mown.
If the working area borders on a paving stone path or
similar that is level with the lawn (+/- 1 cm / 0.4 in.), it is
possible to allow the robotic lawnmower to run a little
over the path. The boundary wire should then be laid 5
cm / 2 in. from the edge of the path. All the grass along
the side of the paving stone path will be cut.
10 cm / 4"
When the working area is divided by a paving stone path
that is level with the lawn, it is possible to allow the
robotic lawnmower to run over the path. It can be an
advantage to lay the boundary wire under the paving
stones. The boundary wire can also be laid in the joint
between the paving stones. Ensure that the tiles are in
level with the lawn to avoid excessive wear on the
robotic lawnmower.
