This iMow (1) is a mulching mower, designed for
autonomous, programmable lawn care. It mows the lawn in
randomly chosen paths. During mulching, the grass
clippings are further shredded in the mowing deck after
cutting. They then fall back into the turf, where they
decompose.
In order for the robotic mower to detect the borders of the
mowing area (A), a perimeter wire (2) must be laid around
that area. A low-voltage electrical signal generated by the
docking station (3) flows through this perimeter wire.
Solid obstacles of sufficient size and weight (5) in the
mowing area are detected by the robotic mower's impact
sensor. Obstacles and areas that the robotic mower must
avoid (4) should be separated from the mowing area using
the perimeter wire.

10.1 Preparing the Lawn and the Robotic Mower for Operation
To prepare the lawn for installation of the perimeter wire:
► Mow the lawn using a conventional lawn mower. An ideal
grass height is 0.8 in. to 1.6 in. (2 cm to 4 cm).
► If the surface is hard and dry, water the mowing area
lightly in order to make it easier to drive in the perimeter
wire stakes.
► STIHL recommends that you install the perimeter wire at
least 11 in. (28 cm) from obstacles or the outer boundary
of your yard, @ 10.4. This will make continuous operation
of your robotic mower more likely. You may reduce
unmowed areas by installing the perimeter wire closer
than 11 in. (28 cm) to obstacles, but the successful
installation will depend on the particular characteristics of
your yard, @ 11.15.
