10.1 General
To ensure a perfect, thick lawn, mow
regularly and keep the grass short.
Do not cut the lawn too short in hot, dry
conditions as it will dry out or burn in the
sun and become unsightly.
The cutting pattern will be better with a
sharp blade than with a blunt one; the
blade should therefore be sharpened
regularly (VIKING specialist dealer).
Cutting performance
The cutting performance (battery running
time) depends on the properties of the
grass and the selected cutting height. The
cutting performance is enhanced by the
following measures:
● Mow the lawn more frequently
● Increase the cutting height
● Reduce speed of propulsion

● Allow the lawn to dry before mowing.
If required, additional STIHL lithium-ion
batteries can be purchased (special
accessories).
