Laying the Boundary Wire
If you intend to peg down the boundary wire:
• Cut the grass very short with a standard lawn mower
or a trimmer where the wire is to be laid. It will then
be easier to lay the wire close to the ground and
the risk of the robotic lawnmower cutting the wire or
damaging the insulation of the wire is reduced.
• Make sure to lay the boundary wire close to the
ground and secure with pegs. The cable must lie
close to the ground so as not to be cut before the
grass roots have grown over it.
• Use a hammer to knock the pegs into the ground.
Exercise care when knocking in the pegs and make
sure the wire is not under strain. Avoid sharp bends
in the wire.
If the boundary wire is to be buried:
• Make sure to lay the boundary wire at least 1 cm and
a maximum of 20 cm in the ground. The cable can be
buried using for instance an edge cutter or a straight
spade.
Use the supplied measurement gage as a guide when
you lay out the boundary wire. This helps you to easily
set the correct distance between the boundary wire and
the boundary/obstacle. The measurement gage is broken
loose from the box.
IMPORTANT INFORMATION
Extra wire must not be placed in coils
outside the boundary wire. This can
disrupt the robotic lawnmower.
Loop for connecting the guide wire
To facilitate the connection of the guide wire to the
boundary wire, it is recommended to wind a ring with
about 20 cm of extra boundary wire at the point where
the guide wire will later be connected. It is a good idea to
plan where the guide wire will be placed before laying out
the boundary wire. Refer to 3.6 Installation of Guide Wire
page 28.
