9.8 Level indicator
The upper part of the grass catcher box
features a level indicator (1).
The flow of air that is created by the rotary
movement of the mowing blade and is
responsible for filling the grass catcher box
raises level indicator (2):
The grass catcher box is filled with
clippings.
When the grass catcher box is full, this
flow of air is reduced and level indicator (3)
drops:
● Empty the filled grass catcher box
(Ö 12.4).
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 (STIHL specialist dealer).
10.2 Cutting performance
The cutting performance (battery running
time) depends on the quality of the grass
and the selected cutting height. The
cutting performance is enhanced by the
following measures:
– Mowing the lawn more frequently
– Increasing the cutting height
– Reducing speed of propulsion
– Allowing the lawn to dry before mowing.
If required, additional STIHL lithium ion
batteries can be purchased (special
accessories).
Eco mode:
The lawn mower features an
eco mode, which improves its
energy efficiency and therefore
its cutting performance.
Eco mode can be switched on and off
using the switch in the battery
compartment. (Ö 9.3)
Function:
The speed of the motor is reduced
automatically when less power is required.
If more power is required, the speed is
increased again within a fraction of a
second.
10.3 Working area for operator
● For safety reasons, the operator must
stay within the working area behind the
handlebar when the motor is running.
Always observe the safety distance
provided by the handlebar.
● The lawn mower must only be operated
by one person. Other persons must
keep out of the danger area. (Ö 4.)
