The battery temperature is within the optimal charging tem-
perature range when the fan is not running. Another reason
for a non working fan might be that it is defective. In this case,
the charging time of the battery might be extended.

Working Advice

Battery Charge-control Indication
The battery is equipped with a charge-control indicator
which indicates its charge condition. The charge-control indi-
cator consists of 3 green LEDs.
Press the button to actuate the charge-control indicator . Af-
ter approx. 5 seconds, the charge-control indicator goes out
automatically.
The charge condition can also be checked when the battery is
removed.
LED Indicators
Continuous lighting of 3 green LEDs ≥ 2/3
Continuous lighting of 2 green LEDs ≥ 1/3
Continuous lighting of 1 green LED
Flashing of 1 green LED
When no LED lights up after actuating the button , the battery
is defective and must be replaced.
For safety reasons, the charge condition of the battery can
only be checked when the garden product is at a standstill.
During the charging procedure, the three green LEDs light up
one after the other and briefly go out. The battery is fully
charged when the three green LEDs light up continuously. The
three LEDs go out again approx. 5 minutes after the battery
has been fully charged.
Temperature Control Indicator
The red LED signals that the battery or the electronics of the
garden product (with battery inserted) are not within the op-
timum temperature range. When this occurs the garden prod-
uct will not operate or not at full capacity.
Temperature Control of the Battery
The red LED flashes when you press the button or the On/Off
switch (with battery inserted): The battery is outside of the
permitted operating temperature range.
The battery switches off at a temperature above 70 °C until
the optimum temperature range is reached again.

Temperature Control of the Garden Product
Electronics
The red LED lights up continuously when pressing the
On/Off switch : The temperature of the garden product elec-
tronics is below 5 °C or above 75 °C.
At a temperature above 90 °C, the electronics of the garden
product switch off until the temperature is within the allowa-
ble temperature range again.
Area of Cut (Battery Duration)
The area of cut (battery duration) depends on lawn condi-
tions, grass density, moisture content, grass length and
height of cut.
Switching the machine on and off frequently during cutting
will also reduce the area of cut (battery duration).
To improve the area of cut (battery duration) it is recommend-
ed to cut more frequently, raise the cutting height and walk at
