Working Advice
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
6cm
4,5cm
Very thin, dry grass
Cutting capacity
Battery with 4.0 Ah up to 200 m
Battery with 5.0 Ah up to 250 m
Battery with 6.0 Ah up to 300 m
To increase the run time an additional battery can be pur-
chased from an authorised customer service agent for Bosch
garden products.
