Battery Usage

The machine can use 1 battery in either battery slot and
still have full functionality.
However it is preferable to use 2 batteries to achieve
maximum performance.
Ideally both batteries should have a similar level of charge.
If batteries have differing charge levels (e. g. Battery I = 50 %,
Battery II = 70 %) the machine will generally empty both bat-
teries at the same rate.
Working Advice
Mulching
The product can be used to mulch, using an optional mulching
kit. (See figure 12 of illustrations for details)
Area of Cut (Battery Duration)
The area of cut (battery duration) depends on lawn condi-
tions, grass density, mositure 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-
