INSTALLATION
Outlining areas inside the working area
If you wish, you can keep the Auto Mower away from certain
places within the working area, such as flowerbeds, fountains
etc. Route the boundary wire out to the section, around the
section and then back along the same route as the boundary
wire was taken out. The same instructions also apply when the
boundary wire is being taken out to an area that lies outside the
first delimited working area. The cables should be laid close to
each other. If the cables are stapled, they should be placed
under the same staples.
NOTE! It is very important to route the boundary wire in
the correct direction around the section, so that it does
not crossover itself, see the illustration.
Installation of search loop
When it’s time to charge the battery, the Auto Mower begins to look
for the search wire. Once the Auto Mower has detected that it has
crossed the search wire, it follows the wire in a clockwise direction
until it reaches the docking side of the charging station. Searching
for the search wire begins when there is enough charge left in the
battery for another hour or two of running time. At some time during
this period the Auto Mower must therefore find the search wire. If the
Auto Mower has plenty of charge left in its battery, it will ignore the
search wire.
The search wire must be laid from the charging station clockwise
around but inside the working area and then back to the charging
station. If the working area consists of several sections that are
joined to each other by passages, the search wire must be laid so
that it goes into each area. See “Planning installation” for examples.
The search wire must never go outside the working area or crosso-
ver itself.
Passages and wire separation distance
Lay the search wire as straight as possible. Make sharp corners
wherever the wire needs to turn. Refer to “Installation of boundary
wire” for advice on possible signal interference from the sur-
roundings.
The search wire should be laid so that its wires are at least 70 cm
from each other and from the boundary wire, see the illustration. In
exceptional cases and along short stretches, e.g. to be able to enter
a narrow passage, or for the final metre before the charging station,
the wire lengths are allowed to lie closer to each other. The search
wire may even be laid across the two parts of the boundary wire that
approach and return from an “island”.
The outgoing search wire from the charging station should lie at
an angle of about 45° to the boundary wire for a distance of at
least 60 cm, see diagram. The final metre of the incoming wire
must go straight in to the charging station, see the illustration.
NOTE! The search wire loop should form a long and narrow
corridor-like shape. Don’t lay the wire lengths further than 2
m apart.

The Auto Mower can mow
areas with an incline of up to
around 15° (27 cm difference in
height per metre). Steeper
areas must be cordoned off
with the boundary wire. If the
optional weights are fitted
(article number 535 09 11-01,
the mower can tackle inclines
slightly steeper than 15°. You
should however avoid laying
the boundary wire on a
downslope. When the grass is
wet the mower may slip if the
slope is too steep, and it might
have problems reversing when
it reaches the wire.
Lay out the boundary wire and secure it to the ground using
staples so that there is no risk of the blades cutting the cable.
Allow the Auto Mower to work for a week and then decide
whether any adjustments to the wire routing are necessary.
After a few weeks the grass will have “weaved in” the cable so
that it is not visible. The boundary cable can also be laid 2-5 cm
(maximum 20 cm) under the soil.
Metallic objects can interfere with the boundary signal. The
boundary wire should therefore not be routed too close to iron
fences or metal manhole covers. In most cases it is sufficient to
lay the boundary wire 30 cm from these types of object. How-
ever, in some cases, such as electric fences, the distance may
need to be greater. If the Auto Mower regularly stops at a
certain point on the lawn and indicates that there is no signal
from the wire (LED 6 is on), this is probably due to this kind of
interference.
If the boundary wire needs to be joined this must be done so that
the joint is waterproof. The best contact is obtained if the joint is
made using Husqvarna’s solder-free connector, item number
535 04 43-01. The joint can also be soldered and then insulated
using shrink tube.
Trees, bushes and the like that can withstand the Auto Mower
pushing against them do not need to be screened off by the
boundary wire. The Auto Mower will reverse anyway when it
hits an obstacle. However, these obstacles must be higher than
the front edge of the chassis, which means about 10 cm or
more. Similarly, obstacles with a gentle slope, for example
stones or large trees with protruding roots, should be either
screened off or removed. Otherwise the Auto Mower can climb
up on such obstacles and probably damage its blades.
NOTE! Twisted cable ends or a single screw terminal
block, insulated with insulation tape are not satisfactory
joints. Ground moisture causes the conductors to
oxidise and after a period of time this will result in a
breakage in the circuit.
