and place the robot lawn mower in the charging
station (19).
5.4.4 Information about charging
The robot lawn mower returns to the charging sta-
tion (19) in each of the following situations:
•
You send the robot lawn mower back manu-
ally.
•
The battery charge level drops below 30%.
•
The end of the daily work time has been
reached.
•
The rain sensor has tripped.
•
The robot lawn mower has become overhea-
ted.
In these cases the robot lawn mower automa-
tically runs along the perimeter wire (18) until it
reaches the charging station (19).
When the robot lawn mower wants to return to the
charging station (19), it will
fi
rst look for the peri-
meter wire (18) and then move along the perime-
ter wire (18) in counter-clockwise direction.
The LED indicator (21) on the charging station
(19) lights up red while charging of the rechargea-
ble battery (22) is in progress.
When the LED indicator (21) on the charging
station (19) turns to green, this indicates that the
rechargeable battery (22) is fully charged. Once
it has been fully charged, the robot lawn mower
resumes operation or remains in the charging sta-
tion until the next work time window (19).
If there is an obstacle on the perimeter wire (18)
during the trip back to the charging station (19),
the robot lawn mower will come to a stop in front
of the obstacle after several attempts and will not
be able to get back to the charging station (19).
Remove all obstacles on the perimeter wire (18).
If the temperature of the rechargeable battery
(22) exceeds 45°C, charging will stop in order
to prevent damage to the rechargeable battery.
Charging resumes automatically once the tempe-
rature has dropped again.
If the temperature of the controller of the robot
lawn mower exceeds 75°C, the robot lawn mower
will return to the charging station (19). Operation
resumes in accordance with the settings once the
temperature has dropped again.
If the rechargeable battery (22) becomes empty
before the robot lawn mower has returned to the
charging station (19), it will not be possible for the
robot lawn mower to start up again. Bring the ro-
bot lawn mower back to the charging station (19)
and leave the main switch (7) switched on. The ro-
bot lawn mower will be charged up automatically.
5.5 Perimeter wire
IMPORTANT! Severed perimeter wires and
consequential damages are not covered by
the warranty!
5.5.1 Laying the perimeter wire
The perimeter wire can be laid both on the ground
and in the ground. The fastening pegs (14) can
break when hammered in if the ground is hard or
dry. Water the lawn before installing the perimeter
wire (18) if the ground is very dry.
•
Installation on the ground
Lay the perimeter wire (18) securely on the
ground and fasten it with the supplied faste-
ning pegs (14) if you do not intend to scarify
or aerate the lawn any time later. You can still
adjust the position of the perimeter wire again
during the first few weeks of using the robot
lawn mower. After a certain time, however,
the perimeter wire will become overgrown
with grass and no longer visible. Install the
perimeter wire with a maximum distance of
1 m between fastening pegs (14). Reduce
the distance between the fastening pegs on
uneven areas of the lawn. Avoid situations in
which the wire is not actually on the ground.
Make sure that the perimeter wire cannot be
severed by the robot lawn mower.
•
Installation in the ground
Bury the perimeter wire in the ground at a
depth of up to 5 cm. This will prevent the
perimeter wire (18) getting damaged during
scarifying or aeration, for example.
Important!
Keep a reserve of 1 m of wire at the rear end of
the charging station so that you can make correc-
tions at a later time.
5.5.2 Narrow points
If the lawn has a narrow point, your robot lawn
mower will be able to operate there as long as the
corridor has a width of at least 1.4 m (80 cm bet-
ween the perimeter wires) and a maximum length
of 8 m (Fig. 3)..
5.5.3 Distance to the garden perimeter
When the robot lawn mower approaches a peri-
meter wire (18), the perimeter wire is detected by
the sensors in the front of the robot lawn mower.
Before the robot lawn mower turns about, howe-
ver, it runs over the perimeter wire (18) by up to
30 cm. Please bear this in mind when planning
your mowing area (Fig. 6a).
