5.4 Charging station
5.4.1 Position of the charging station
Begin by determining the best position for the
charging station (19). You need an outdoor so-
cket outlet with 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 on level with the turf. Make sure that the
area is fl at and dry. Ideally you should position the
charging station (19) at the edge of the mowing
area. Please note that the power cable for the
charging station (19) should not be laid inside the
mowing area. If it is, it will need to be buried to
avoid it being damaged by the robot lawn mower.
Position the charging station (19) together with
the guide cable (24) on an open area free of
obstacles which is as accessible as possible from
all directions. Avoid positioning the charging sta-
tion (19) in hard-to-reach corners or in areas that
can be reached only through bottlenecks.
The maximum distance from the charging station
(19) to a lawn boundary is not allowed to exceed
1000 m. This serves to reduce the risk of theft. At
greater distances the GNSS LED (54) will turn
yellow and the robot lawn mower cannot be ope-
rated in Main Area mode. The mower's distance
from the charging station (19) is irrelevant for ope-
ration in Secondary Area mode. To guarantee ef-
fi cient and automatic mowing it is recommended
to restrict the distance from the lawn boundary to
the charging station (19) to 50 m. As the distance
from the charging station (19) increases, it is
possible that the robot lawn mower will no longer
have enough battery power for it to return to the
charging station (19). Use a battery with greater
capacity for larger mowing areas.
Select a position in the shade because it is best
to charge the battery in cool surroundings. Tall
buildings or trees can weaken the GNSS signal
so that the robot lawn mower is no longer able
to fi nd its way back to the charging station (19)
automatically. It is important therefore to keep a
reasonable distance away from tall buildings and
trees and to make sure that the charging station
(19) lies under the open sky. Also note that the
guide cable (24) must be laid 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.
5.4.2 Localization of the charging station
When the battery is almost empty, the robot lawn
mower will return to the charging station (19) by
GB
following the guide cable (24). The robot lawn
mower compares its actual position with the cali-
brated position of the charging station in regular
intervals with the help of GNSS. The robot lawn
mower travels in the direction of the charging
station (19) and looks for the guide cable (24) in
several steps. As it does so, the robot lawn mower
stops now and again before setting off if necessa-
ry in a diff erent direction in order to reach the gui-
de cable (24). When the robot lawn mower gets
near to the guide cable (24) it will begin to detect
its position with the help of rotary movements and
the strength of the signal transmitted by the guide
cable (24).
If the robot lawn mower comes across an obstac-
le or a lawn boundary while mowing, this position
will be saved. The map produced as the result
helps the robot lawn mower to fi nd the charging
station (19) more quickly.
When the robot lawn mower reaches the guide
cable (24) it will follow it counter-clockwise to the
charging station (19). Make sure, therefore, that
the charging station (19) faces in the right direc-
tion when you position it (Fig. 4a).
5.4.3 Connecting the charging station to the
power supply unit
1. Before you connect the charging station (19)
to the power supply, check that the mains po-
wer supply is 100-240 V at 50/60 Hz.
2. Connect the power supply unit (20) directly to
a socket outlet. Do not use the cable for any
other use.
3. Do not use the power supply unit if it is da-
maged (20). In the event of any damage to
cables or the power supply unit (20), contact
an authorized professional immediately for
replacement.
4. Do not charge the robot lawn mower in a
damp location. Do not charge the robot lawn
mower at temperatures above 40°C or below
5°C.
5. Keep the robot lawn mower and the power
supply unit (20) away from water, sources of
heat and chemicals. Keep the cable of the po-
wer supply unit (20) away from sharp edges
in order to prevent damage.
6. Connect the power supply unit (20) to the
charging station (19) (Fig. 4b).
7. With the main switch (7) set to ON and with a
battery inserted, place the robot lawn mower
in the charging station (19) and charge it fully
before you use it for the fi rst time.
