Four different cutting heights between 
28 mm and 85 mm can be set.
Level 1 = lowest cutting height
Level 4 = highest cutting height
1 Setting the rear cutting height
● Set the required cutting height at the 
rear axle (1).
For this purpose, support the machine 
with one hand and move the rear axle to 
the desired level on one side first and 
then on the other.
Ensure that the rear axle is at the same 
level on the left and right sides (rear 
axle parallel to the housing).
2 Setting the front cutting height
● Push the cutting height adjustment 
lever (2) outwards, move to the desired 
level and allow it to engage.
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:
– blunt mowing blade
– mowing excessively high grass or 
cutting height adjusted too low
– excessive rate of feed
– inadequate cleaning of the cooling air 
guide (inlet slots)
Risk of injury!
The setting on the front and rear 
axles must be identical.
10. Notes on working with 
the machine

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