• Any parallel boundary wires at a
distance of 5 mm or less are not de-
tected by the automatic lawn mower
and are passed over.
• Avoid creating corners with a 90° an-
gle. Instead, split these into two 45°
angles (see figure
• The automatic lawn mower's sen-
sors are able to detect and evade
stationary and solid obstacles (walls,
garden furniture, etc.) larger than 100
mm. Protect sensitive obstacles (e.g.
flowerbeds) on the lawn area with the
boundary wire (6).
• Keep a distance of at least 1 m be-
tween bordered obstacles. Border ob-
stacles that do not meet this minimum
distance as a single obstacle (see
figure k ).
Make sure that the boundary wire
(6) does not intersect at any point.
This can lead to faults and failures
in the automatic lawn mower's op-
eration.
Trees
The automatic lawn mower detects trees
as a normal obstacle. However, protruding
roots may damage the underside/blades
(23).
We recommend using the boundary wire
(6) to also border trees.
Rocks
• Remove small rocks (lower than
100 mm) from the lawn area. These
may damage the device and the
blades (23).
• The automatic lawn mower detects
rocks (taller than 100 mm) as normal
obstacles.

l
We recommend using the boundary
wire (6) to also border rocks.
Gradients
The automatic lawn mower is able to
traverse uphill gradients up to max. 20°
(35%).
The boundary wire should not be installed
across uphill gradients greater than 20°
and downhill gradients greater than 10°
(17%).
Make sure that a distance of at
least 30 cm is maintained between
the boundary wire (6) and an ob-
stacle on an uphill gradient and at
least 40 cm on a downhill gradient.
Ponds/pools
Ponds and pools should be bordered by
the boundary wire (6) where possible
or designed so that the automatic lawn
mower cannot enter the water. This may
seriously damage the device's electronics.
Paths/roads
The automatic lawn mower can easily
cross paths and roads at ground level.
If height differences exist between the
lawn area and path/road, border off the
path/road with a safety margin of approx.
40 cm.
Narrow passages
Narrow passages on the bordered lawn
area should be at least 1.2 m wide and no
more than 8 m long (see figure
GB
m ).
