9 Key Features
clippings are further shredded in the mowing deck after 
cutting. They then fall back into the turf, where they 
decompose.
In order for the robotic mower to detect the borders of the 
mowing area (A), a perimeter wire (2) must be laid around 
that area. A low-voltage electrical signal generated by the 
docking station (3) flows through this perimeter wire.
Solid obstacles of sufficient size and weight (5) in the 
mowing area are detected by the robotic mower's impact 
sensor. Obstacles and areas that the robotic mower must 
avoid (4) should be separated from the mowing area using 
the perimeter wire.
9.1 Key Features
WARNING
The robotic mower is equipped with several devices to help 
reduce the risk of personal injury or property damage during 
use. If a safety device has a malfunction, do not operate the 
robotic mower and take the it to an authorized STIHL iMow 
servicing dealer to be repaired.
1. STOP button
If you push the STOP button, the mower and its mowing 
blade will stop and the display will show the message "STOP 
button pressed." The robotic mower cannot be operated 
while this message is active, @ 22.1.
If you want to resume automatic mowing, the robotic mower 
will ask whether automatic operation is to be continued. To 
continue automatic operation:
► Confirm the message "STOP button pressed" by pressing 
the OK button.
► Select "Yes" and press the OK button.
The robotic mower resumes automatic mowing in 
accordance with the mowing plan.
► Select "No" and press the OK button to have the robotic 
mower remain stationary in the mowing area and switch 
off automatic mowing, @ 14.3.
2. Disabling device
► To activate the disabling device in the "Commands" menu, 
select "Lock iMow" and confirm by pressing the OK button, 
@ 14.3.
► To activate the disabling device in the "Settings" menu, 
open the "Safety" submenu, select "Lock iMow" and 
confirm by pressing the OK button, @ 15.4.
To deactivate the disabling device:
► Wake up the robotic mower, if required, by pressing any 
button.
► Press the Back button and the OK button in the sequence 
illustrated on the display.
Once the disabling device is deactivated, the robotic 
mower can be operated again.
3. Impact sensor
The hood is designed to function as an impact sensor.
During automatic operation, the robotic mower stops if the 
hood contacts a solid obstacle taller than 3.9 in. (10 cm). 
The robotic mower then turns and continues automatic 
mowing in another direction. If the impact sensor is triggered 
too frequently, the mowing blade will stop rotating.
NOTICE
The impact sensor may not detect certain obstacles, such as 
small flower pots or other lighter objects, which can be 
knocked over or damaged. STIHL recommends removing 
obstacles or blocking them off by creating restricted areas 
through the placement of the perimeter wire, @ 11.6.
9 Key Features
To activate the disabling device, press and hold 
the STOP button for 5 seconds. The mower and 
its mowing blade stop and the display shows the 
message "Disab. device. Unlock using the 
indicated key combination." The robotic mower 
cannot be operated while this message is 
active,@ 22.1.
