3.5.3.1 Secondary areas
If the working area consists of two areas, which the
robotic lawnmower has difficulty travelling between, it is
recommended to set up a secondary area. Instances of
this are 45% slopes or a passage that is narrower than
60 cm / 24 in. Lay the boundary wire then around the
secondary area so that it forms an island outside of the
main area. The robotic lawnmower must be moved
manually between the main and secondary area when
the lawn in the secondary area has to be cut.

the robotic lawnmower cannot travel on its own from the

mode - Start on page 40 . In this mode, the robotic
lawnmower will never look for the charging station but
will mow for the chosen time or until the battery runs out.
Place the robotic lawnmower in the charging station to
charge the battery. If the main area has to be cut
straight after charging, tap on

3.5.3.2 Passages when mowing
Long and narrow passages and areas narrower than 1.5
- 2 m / 3.2 - 6.5 ft. should be avoided. It is then a risk
that the robotic lawnmower travels around in the
passage or area for a period of time. The lawn will then
look flattened. The narrowest possible passage for the
robotic lawnmower is 60 cm / 24 in (between boundary
wires).
Note: In passages narrower than 2 m / 6.5 ft. (between
boundary wires) Husqvarna recommends that a guide
wire is installed.

3.5.3.3 Slopes
The robotic lawnmower can operate in slopes. The
maximum gradient is defined as percentage units (%)
and is calculated as difference in elevation in
centimetres for every meter. Inside the working area the
robotic lawnmower can mow areas which slope up to
45%. Areas that slope more must be isolated with the
boundary wire.
The boundary wire can be laid across a slope that slants
less than 15%.
0-15
100 cm / 40"
The boundary wire should not be laid across a slope that
is steeper than 15%. There is a risk that the robotic
lawnmower will find it difficult to turn there. The robotic
lawnmower will then stop and the
fault message is displayed. The risk is at its greatest in
damp weather conditions, as the wheels can slip on the
wet grass.
15- %
100 cm / 40"
However, the boundary wire can be laid across a slope
steeper than 15% if there is an obstacle that the robotic
lawnmower is allowed to collide with, for example, a
fence or a dense hedge.
When a part of the working area's outer edge slopes
more than 15%, the boundary wire must be laid about
20 cm / 8 in. in on the flat ground before the beginning of
the slope.
