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.

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