Acute Corners; Confined Areas; Installing Linking Sections; No-Go Areas - Stihl RMI 422 P Gebrauchsanleitung

12.6 Acute corners

The perimeter wire is routed as illustrated
in acutely angled lawn corners (45° - 90°).
The two angles must have a clearance of
at least 28 cm so that the robotic mower
can follow the edge.
Corners smaller than 45° should not be
included in the wire routing.

12.7 Confined areas

If confined areas are to be installed,
switch off offset drive home
(passage) ( 11.13) or install guide
loops. ( 12.12)
The robotic mower travels automatically in
all confined areas, provided the minimum
wire clearance is maintained. Narrower
areas of the mowing area must be blocked
off through appropriate routing of the
perimeter wire.
If two mowing areas are linked via a
narrow passage that can be travelled on, a
corridor can be installed. (

The minimum wire clearance is 44 cm.
This results in the following space
requirements in confined areas:
– between high obstacles with a height
+/- 1 cm, such as walls 100 cm,
– between adjoining areas that can be
travelled on with a stepped area height
of less than +/- 1 cm, such as paths
44 cm.

12.8 Installing linking sections

The robotic mower ignores the perimeter
wire signal if the wires are routed parallel
and close together. Linking sections must
be installed
– where secondary areas are to be
installed. (
– where no-go areas are necessary.
( 12.9)
12.11)
12.10)
STIHL recommends laying linking
sections together with the relevant
no-go areas or secondary areas
during wire routing.
In the case of retrospective
installation, the wire loop must be
cut and linking sections must then
be integrated using the wire
connectors supplied. (
In linking sections, the perimeter wire (1)
must be routed parallel, the wires must not
cross and must be close to one another.
Attach the linking section to the ground
with a sufficient number of fixing pins (2).

12.9 No-go areas

No-go areas have to be installed
– around obstacles that the robotic
mower must not touch,
– around obstacles that are not
sufficiently sturdy,
