lawn mower. The quality of the installation
work aff ects how eff ectively the robot lawn
mower works later on.
5.1 How it works
The robot lawn mower chooses its direction on
a random basis. The robot lawn mower works its
way over every area which is enclosed within the
perimeter wire (18), so that the entire garden gets
mowed. Whenever the robot lawn mower detects
a correctly installed perimeter wire (18), the robot
lawn mower turns about and drives in a diff erent
direction within the area. All zones that you wish
to protect within the lawn area – e.g. garden
ponds, trees, furniture or fl ower beds – must be
cordoned off by the perimeter wire (18). The pe-
rimeter wire (18) must form a closed circuit. If the
robot lawn mower bumps into an obstacle within
the mowing area, it reverses and then continues
mowing in a diff erent direction (Fig. 3).
5.2 Sensors
The robot lawn mower is equipped with a number
of safety sensors.
•
Lifting sensor:
If the robot lawn mower is raised at the back
by more than 30° from the ground or if a front
wheel (12) loses contact with the ground, the
robot lawn mower and the rotation of the bla-
des (10) will be stopped immediately.
•
Tilting sensor:
If the robot lawn mower tilts severely in any di-
rection, the robot lawn mower and the rotation
of the blades (10) are stopped immediately.
•
Obstruction sensor:
The robot lawn mower is able to detect obsta-
cles in its path. If the robot lawn mower colli-
des with an obstacle, the robot lawn mower
and the rotation of the blades will be stopped
immediately and the mower will reverse away
from the obstacle.
•
Rain sensor:
The robot lawn mower is equipped with a rain
sensor (5) to prevent the robot lawn mower
from operating in the rain. The robot lawn mo-
wer returns to the charging station (19) when
it detects rain and is completely recharged
there. Once the rain sensor (5) is dry again,
the robot lawn mower will stay in the charging
station (19) for another two hours. Only then
will it begin working again, provided it is still
in an active time window. If the rain sensor (5)
has been activated (this is recommended in
order to exert less stress on the lawn), you will
see a bright cloud in the display (50). If the

sensor triggers, a dark cloud with rain drops
will appear. Do not short-circuit the two metal
sensors with metal or any other conductive
material. This will impede the correct operati-
on of the robot lawn mower.
5.3 Preparations
First, draw a sketch of your lawn. Include obstac-
les in your sketch and draw up a plan for how you
intend to protect them. This will make it easier to
fi nd a good position for the charging station (19)
and to lay the perimeter wire (18) around bushes,
fl ower beds, etc. (Fig. 4). If the grass is taller than
60 mm it has to be shortened fi rst to avoid expo-
sing the robot lawn mower to excessive load and
adversely aff ecting its operating effi ciency. Use a
conventional lawn mower or trimmer to do this.
Remove all loose objects from the lawn which
could get damaged by the robot lawn mower or
damage the robot lawn mower itself.
Have the following tools ready: A hammer, tongs,
a wire stripper and a spirit level (optional).
Fitting the battery
Open the battery compartment cover (9). Press
the of the pushlock button of the rechargeable
battery (22) and push the rechargeable battery
(22) into the mount provided. Close the battery
compartment cover (9) and make sure that it lat-
ches in place correctly. (Fig. 10)
5.4 Charging station
5.4.1 Position of the charging station
Determine the best position for the charging sta-
tion fi rst (19). An outdoor socket outlet is required
which supplies a permanent supply of electricity
so that the robot lawn mower works at all times.
The charging station (19) must be placed on a
fl at area at the level of the turf. Make sure that the
area is fl at and dry. Select a position which is in
the shade, because it is best if the rechargeable
battery (22) is charged up in a cool area. Also
note that the perimeter wire has to be laid in a
straight line for least 2 m in front of the charging
station (19) (Fig. 5a). Curves immediately in front
of the charging station (19) could cause problems
when docking for charging.
5.4.2 Localization of the charging station
When the rechargeable battery (22) is almost em-
pty, the robot lawn mower returns to the charging
station (19) by following the perimeter wire (18) in
a counterclockwise direction until it reaches the
charging station (19). Make sure, therefore, that
the charging station (19) faces in the right direc-
