3. INSTALLATION
If the working area borders against a flat path or the
like that lies level with the lawn, it is possible to allow
Automower to run a little over the path. The boundary
wire should then be laid 4" from the edge of the path.

When the working area is divided by a flat slab path
that is level with the lawn, it is possible to allow
Automower to run over the path. It can be an
advantage to lay the boundary wire under the slabs.
The boundary wire can also be laid in the joint
between the slabs.
Note!
Automower must never run over a gravel path
or similar material, which can damage the blades.
If the working area borders against, for example,
3012-534
pools of water the boundary wire should be
supplemented with a fence or the like. The height must
then be at least 6". This will prevent Automower, under
any circumstances, coming outside of the working
area.
When Automower searches for the charging station or
follows the loop according to the function Follow loop
(3-2) (see page 52), it runs along the side of the
boundary wire at a specific distance. The Corridor
width (3-2-3) function determines the distance from the
boundary wire that the mower shall run. It is
recommended to state as high a Corridor width value
as possible. A high Corridor width value reduces the
risk of tracks forming. For more information about
Corridor width (3-2-3), see page 55.
In exceptional cases Automower can be set to
straddle the boundary wire, that is to say, half the
mower inside the loop and the other half outside. The
boundary wire must then be kept at a distance of
about 16" from all the boundaries of the working area
and from the edges of a passage.
