LED Indication Battery Capacity
Flashing of 1 green LED Reserve
When no LED lights up after pressing the button, then 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 green LEDs go out again approx. 5minutes after
the battery has been fully charged.
Temperature Monitoring Indicator of the battery
The red LED of the temperature monitoring indicator signals
that the battery or the electronics of the garden product
(with battery inserted) are not within the optimum temperat-
ure range. When this occurs, the garden product will not op-
erate or not at full capacity.
Temperature Monitoring of the Battery
The red LED flashes when pressing 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 allowable operating-temperature range is reached again.
Temperature Monitoring of the Garden
Product's Electronics
The red LED lights up continuously when pressing the On/
Off switch: The temperature of the garden product's 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 allow-
able operating-temperature range again.
Cutting Capacity (Battery Operating Duration)
The cutting capacity (battery operating duration) depends
on lawn properties, such as grass density, moisture content,
grass length and height of cut.
Switching the machine on and off frequently during cutting
will also reduce the cutting capacity (battery operating dura-
tion).
To improve the cutting capacity (battery operating dura-
tion), it is recommended to cut more frequently, increase
the cutting height and walk at an appropriate pace.
The example below shows the connection between cutting
height and cutting capacity with regard to three batteries.
Cutting Conditions
Very thin, dry grass
Cutting capacity
Battery with 2.0Ah up to 250 m
2
Battery with 4.0Ah up to 500 m
2
Battery with 6.0Ah up to 750 m

To increase the run time an additional battery can be pur-
chased from an authorised customer service agent for Bosch
garden products.
