11 Installing the Perimeter Wire
► Install reserve lengths of perimeter wire at regular
intervals near difficult passages. Doing so make it easier
to modify the installation of the perimeter wire or docking
station if that should become necessary.
► If burying the perimeter wire, place it at a depth of no more
than 3.9 in. (10 cm).
Burying the perimeter wire in the ground may influence
signal reception, particularly if flagstones or paving stones
are laid over the perimeter wire. The robotic mower may
then travel along at a greater offset to the perimeter wire,
requiring more space in corridors, confined areas and when
traveling along edges. Adjust the location and depth of the
perimeter wire if necessary.
NOTICE
Avoid contacting the perimeter wire when de-thatching or
aerating the lawn. Also use caution when operating a line
trimmer near the perimeter wire. De-thatching, aerating and
trimming operations can result in a cut or damaged
perimeter wire. Refer to your sketch of the mowing area and
take special care to avoid the perimeter wire when
performing these operations.
11.2 Making a Sketch of the Mowing Area
STIHL recommends making a sketch of the mowing area
that includes the following:
– The contour of the mowing area including important
obstacles, borders and any restricted areas which the
robotic mower must not mow, @ 26.
– The location and position of the docking station, @ 10.3.
– The location of the perimeter wire and any wire
connectors you have installed, @ 10.4.
– If you change the dimensions of your mowing area after
the initial setup (by adding sections or moving the
perimeter wire, for example), re-link the iMow to the
docking station (@ 10.6) and run the test edge function
(@ 15.3) to measure the length of the perimeter wire and
develop a new mowing plan.

11.3 Measuring Wire Clearances with the
iMow Ruler
1
The perimeter wire (1) can be routed next to surfaces such
as patios and paths as long as the surface is flat, level with
the grass, and allows the robotic mower to travel unimpeded
by obstacles. If necessary, the robotic mower may travel
with one rear wheel outside the mowing area.
The maximum height difference between lawn area (2) and
obstacle (1) must not exceed 0.4 in. (1 cm).
