4. Do not charge up the robot lawn mower in a
damp location. Do not charge up the robot
lawn mower at temperatures above 40°C or
below 5°C.
5. Keep the robot lawn mower and the power
supply unit (13) away from water, sources of
heat and chemicals. Keep the cable of the po-
wer supply unit (13) away from sharp edges
in order to prevent damage.
6. Connect the power supply unit (13) to the
charging station (19). (Fig. 5c)
To charge up the rechargeable battery (22) for
the robot lawn mower straight away while you
are still doing the installation work,
fi
rst switch on
the robot lawn mower with the main switch (7)
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 runs back to the
charging station (19), it looks for the perimeter
wire (18). To ensure that the robot lawn mower
arrives at the charging station (19) at an optimum
angle, the robot lawn mower runs a short distance
along the perimeter wire (18) in a clockwise direc-
tion
fi
rst. Then the robot lawn mower turns in the
right direction and follows the perimeter wire (18).
This ensures that the robot lawn mower always
drives into the middle of the charging station (19)
in a straight line.
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 (18) 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 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
