During the charging procedure, the 3 green bat-
tery LEDs light up one after the other and briefly
go out. The battery is fully charged when the
3 green LEDs light up continuously. Approx.
5 minutes after the battery has been fully
charged, the 3 green LEDs go out again.
Temperature Control Indicator (see main figure)
The red LED 15 signals that the battery or the
electronics of the product are not within the opti-
mum temperature range. The product will not op-
erate at full capacity.
Temperature Control of the Battery
The red LED 15 flashes when the battery is not
within the optimum temperature range (–10 to
+60 °C) and button 13 or the On/Off switch 1 is
pressed.
The battery switches off at a temperature above
70 °C until the optimum temperature range is
reached again.
Temperature Control of the product Electron-
ics
The red LED 15 lights up continuously when
the temperature of the product electronics are
above 75 °C and the On/Off switch 1 is pressed.
At a temperature above 90 °C, the electronics
switch off the product until the temperature is
within the allowable operating temperature range
again
Area of Cut (Battery Duration)
The area of cut (battery duration) depends on lawn
conditions, grass density, mositure content, grass
length and height of cut.
Switching the product on and off frequently during
cutting will also reduce the area of cut (battery dura-
tion).
To improve the area of cut (battery duration) it is rec-
ommended to cut more frequently, raise the cutting
height and walk at a normal pace.
