The STIHL robotic mower 
can be operated reliably 
and without interference 
in close vicinity to other 
robotic mowers. The wire 
signal meets the EGMF 
(European Garden 
Machinery Federation) standard with 
regard to electromagnetic emissions.
The machine is equipped with several 
safety devices for safe operation and for 
the prevention of improper use.
5.1 STOP button
When the red STOP button on the top of 
the robotic mower is pressed, operation of 
the machine is stopped immediately. The 
mowing blade comes to a standstill within 
a few seconds and the message "STOP 
button pressed" appears on the display. 
The robotic mower cannot be operated 
and is safe while the message is active. 
(Ö 23.)
When automatic mowing is 
switched on, following 
confirmation of the message with 
OK, the system enquires 
whether automatic operation is to be 
continued.
If the response is Yes, the robotic mower 
continues to mow the mowing area in 
accordance with the mowing plan.
If the response is No, the robotic mower 
remains stationary in the mowing area and 
automatic mowing is switched off. (Ö 15.4)
5.2 Disabling device
The robotic mower must be 
disabled prior to any 
maintenance or cleaning work, 
prior to transportation and prior 
to inspection.
The robotic mower cannot be operated 
when the disabling device is activated.
Activating the disabling device:
– Press and hold the STOP button
– in the More menu,
– in the Safety menu.
Activating the disabling device via the 
More menu:
● In the "More" menu, select the "Lock 
iMOW®" entry and confirm with the OK 
button. (Ö 11.8)
Activating the disabling device via the 
Safety menu:
● In the "More" menu, open the "Settings" 
and "Safety" submenus. (Ö 11.16)
● Select the "Disab. device" entry and 
confirm with the OK button.
Deactivating the disabling device:
● When required, wake up the machine 
by pressing any button.
● Unlock the robotic mower using 
the illustrated button 
combination. For this purpose, 
press the OK button and the 
Back button in the sequence 
shown on the display.
5.3 Protective covers
The robotic mower is equipped with 
protective covers that prevent inadvertent 
contact with the mowing blade and the 
clippings.
These include, in particular, the hood.
5.4 Impact sensor
The robotic mower is equipped with a 
movable hood which serves as an impact 
sensor. During automatic operation, it 
immediately comes to a standstill if it 
contacts a solid obstacle which has a 
specific minimum height (8 cm) and is 
firmly attached to the ground. It then turns 
to face another direction and continues 
mowing. If the impact sensor is triggered 
too frequently, the mowing blade is also 
stopped.
5. Safety devices
Risk of injury!
If a safety device is found to be 
defective, the machine must not be 
operated. Consult a specialist 
dealer; STIHL recommends STIHL 
specialist dealers.
Pressing and holding the STOP 
button also activates the disabling 
device. (Ö 5.2)
Impacts against obstacles occur 
with a certain force. Sensitive 
obstacles, e.g. light objects such as 
small flower pots, can therefore be 
knocked over or damaged.
STIHL recommends removing 
obstacles or blocking them off by 
means of no-go areas. (Ö 12.9)
