1 0. 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).
1 0.2 Mowing on slopes
For safety reasons, the lawn mower
must not be used on inclines of
more than 25°. A slope inclination of
25° (46.6%) corresponds to a vertical
height increase of 46.6 cm for a 100 cm
horizontal distance.
1 0.3 Correct motor load
Do not switch on the lawn mower in tall
grass or at the lowest cutting height.
The lawn mower load must never cause
the motor speed to drop significantly.
If the speed drops, select a higher cutting
height setting and/or reduce the rate of
feed.

In order to prevent damage, the
lowest cutting height must only be
used on even lawns (without
bumps).
