Level 6 = 75 mm
Setting the cutting height:
Hold the handle (1), pull the lever (2)
upwards and hold.
Set the required cutting height by
moving the machine upwards and
downwards. The current cutting height
can be read off at the cutting height
indicator (3) by means of the
marking (4).
Release the detent lever (2) and allow it
to engage.
9.7 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 the 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 the level
indicator drops (3):
Empty filled grass catcher box (Ö 12.5).
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 9.2)
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.)
10.4 Correct motor load
Do not switch the lawn mower on in tall
grass. Select a higher cutting height
setting if the motor is difficult to start.
The lawn mower load must never cause
the motor speed to drop significantly.
If the speed drops when mowing tall grass,
select a higher cutting height setting
and/or reduce the speed of propulsion.
10.5 If the mowing blade blocks
Switch off the motor immediately and
disconnect the safety plug. Then eliminate
the cause of the fault.
10.6 Thermal motor overload
protection
The electronics switch off the motor if it
becomes overloaded during operation.
Three red LEDs in the battery illuminate if
a thermal overload occurs. (Ö 8.5)
Causes for an overload:

the machine

When eco mode is switched on, the
speed is reduced automatically
when less power is required.
