3.4.3.1 To put the boundary wire in a slope
The product can operate in 50% slopes. Slopes that are
too steep must be isolated with the boundary wire. The
gradient (%) is calculated as the vertical height divided
by the horizontal distance. Example: 10 cm / 100 cm =
10%.

10 cm/4"
• For slopes steeper than 50% inside the work area,
isolate the slope with boundary wire.
• For slopes steeper than 25% along the outer edge
of the lawn, put the boundary wire 20 cm / 8 in. (A)
from the edge.
• For slopes adjacent to a public road, put a barrier
of minimum 15 cm / 6 in. along the outer edge of
the slope. You can use a wall or a fence as a
barrier.
3.4.3.2 Passages
A passage is a section that has boundary wire on each
side and that connects 2 parts of the work area. The
distance between the boundary wire on each side in the
passage must be a minimum of 60 cm / 24 in.
Note:
If a passage is less than 2 m / 6.5 ft. wide,
install a guide wire through the passage.
The recommended minimum distance between the
guide wire and the boundary wire is 30 cm / 12 in. The
product always runs to the left of the guide wire as seen
facing the charging station. It is recommended to have
as much free area as possible to the left of the guide
wire (A).

3.4.3.3 To make an island
CAUTION:
of boundary wire across the other. The
sections of boundary wire must be parallel.
CAUTION:
across the boundary wire.
CAUTION:
that are less than 15 cm / 5.9 in. in height.
Isolate or remove obstacles that slope
slightly, for example, stones, trees or roots.
This will prevent damage to the blades of the
product.
To make an island, isolate areas in the work area with
the boundary wire. We recommend to isolate all stable
objects in the work area.
