• Secure the wire to the ground with pegs.
Staple down the boundary wire if you want to make
adjustments to the boundary loop during the first few
weeks of operation. After a few weeks the grass will
have grown over the wire, making it no longer
visible. Use a hammer/plastic mallet and pegs.
• Bury the wire.
Bury the boundary wire if you want to dethatch or
aerate the lawn. If necessary, both methods can be
combined so one part of the boundary wire is
stapled down and the other is buried. The wire can
be buried for instance using an edge cutter or a
straight spade. Make sure to lay the boundary wire
at least 1 cm / 0.4 in. and a maximum of 20 cm / 8
in. in the ground.
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 35 m / 14
ft. from the wire at any point in the working area.
• The wire is no more than 800 m / 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 35 cm / 14 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 30 cm / 12
in. inside the working area. This prevents the wheels
from driving into the ditch or up onto the kerbstone,
which might lead to excessive wear on the robotic
