5.4.4 Information about charging
The robot lawn mower will return to the charging
station (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.
•
When twilight falls, making it impossible for
the camera unit to work correctly.
In this case the robot lawn mower looks for the
guide cable (24) and then travels automatically
clockwise along the guide cable (24) as far as the
charging station (19).
While the battery is being charged, the battery
LED (55) of the robot lawn mower will fl ash green.
When the battery is fully charged, the battery LED
(55) and the LED display (19a) at the charging
station (19) will light up green. Once it has been
fully charged, the robot lawn mower will resume
operation or remain in the charging station (19)
until the next work time window.
If there is an obstacle on the guide cable (24)
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 guide cable (24).
If the temperature of the battery exceeds 45 °C,
charging will stop in order to prevent damage to
the battery. Charging will resume automatically
once the temperature has dropped again.
If the temperature of the robot lawn mower con-
troller exceeds 65 °C, the robot lawn mower will
return to the charging station (19). Operation will
resume in accordance with the settings once the
temperature has dropped again. If the battery
becomes empty before the robot lawn mower has
returned to the charging station (19), the robot
lawn mower will be unable to start up again. Bring
the robot lawn mower back to the charging station
(19) and leave the main switch (7) switched on.
The robot lawn mower will be charged up auto-
matically.

consequential damages are not covered by the

5.5.1 Laying the guide cable
The guide cable (24) can be laid both on the
ground and in the ground. The fastening pegs (23)
might break while they are being hammered into
hard or dry ground. If the ground is very dry, water
the lawn before installing the guide cable (24).
•
Installation on the ground
Lay the guide cable (24) securely on the
ground and fasten it with the supplied faste-
ning pegs (23). You can adjust the position of
the guide cable (24) during the fi rst weeks of
using the robot lawn mower. In the course of
time, however, the guide cable will become
overgrown with grass and will be no longer
visible. Install the guide cable (24) with a ma-
ximum distance of 1 m between the fastening
pegs (23). Avoid situations in which the guide
cable (24) is not actually lying on the ground.
Make sure that the guide cable (24) cannot be
severed by the robot lawn mower. While the
robot lawn mower is mowing, it will travel with
its activated mower unit over the guide cable .
•
Installation in the ground
Bury the guide cable (24) in the ground at a
depth of up to 5 cm. This will prevent damage
to the guide cable (24) during for example
scarifying or aeration.
Important!
Because the guide cable (24) is not always laid
along the lawn boundary, it is important to make
a note of where the guide cable (24) is positioned
so that it is not damaged during future garden
projects. Make a drawing or take photos to docu-
ment the arrangement. If the guide cable (24) is
not buried in the ground you should not scarify or
aerate near the guide cable (24) so as to avoid
damaging it.
5.5.2 Installing the search loop
•
The guide cable (24) forms a search loop
which is used by the robot lawn mower to find
its way back to the charging station (19).
•
Lay the guide cable (24) in a straight line for
least 1 m in front of the charging station (19)
and for at least 0.5 m behind the charging
station (19) (Fig. 4a). Curves immediately in
front of the charging station (19) could cause
problems when docking for charging.
•
The guide cable (24) should enclose a mini-
mum area of 5 m² (Fig. 4a). It is recommen-
ded to use the entire length of the guide cable
(24) and to lay it in the shape of a square as
far as possible. The search loop should be ori-
entated so that the robot lawn mower is well
