4. How the robotic mower
works
4.1 Operating principle
EN
The robotic mower (1) is designed for the
automatic mowing of lawns. It mows the
lawn in randomly selected paths.
In order for the robotic mower to detect the
borders of the mowing area A, a
perimeter wire (2) must be routed around
that area. A wire signal generated by the
docking station (3) flows through this
perimeter wire.
Solid obstacles (4) in the mowing area are
reliably detected by the robotic mower by
means of an impact sensor. Areas (5) that
0478 131 8349 A - EN
the robotic mower is not to enter and
obstacles that need to be avoided must be
separated from the remaining mowing
area using the perimeter wire.
When automatic mowing is switched on
the robotic mower independently leaves
the docking station and mows the lawn
during the active times (Ö 11.7). The
robotic mower automatically travels to the
docking station to recharge the battery.
The number and duration of the mowing
and charging operations within the active
times are adapted fully automatically. This
guarantees that the required weekly
mowing duration is always achieved.
When automatic mowing is switched
off and for mowing operations
independent of the active times, a
mowing operation can be activated using
the Mow button or with the command
"Start mowing" or "Start time-delayed
mowing". (Ö 11.5)
9
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.
4.2 Manual mowing
With the robotic mower (1), it is also
possible to mow the lawn as with a
manually operated lawn mower. For this
purpose, remove the control panel (2),
select the "Hand control" option in the
"Commands" menu, activate the mowing
blade and self-propulsion and walk behind
the robotic mower. (Ö 15.6)
The impact sensor and edge
limitation are disabled during
manual mowing.
5. Safety devices
The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.
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.
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 lawn 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 11.5)
Pressing and holding the STOP
button also activates the disabling
device. (Ö 5.2)
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 Commands menu
–in the Safety menu.
Activating the disabling device via the
Commands menu:
● In the "Commands" menu, select the
"Lock iMow" entry and confirm with the
OK button. (Ö 11.5)
Activating the disabling device via the
Safety menu:
● Open the "Safety" submenu in the
"Settings" menu. (Ö 11.16)
● Select the "Lock iMow" 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 Mow button and the OK button in the sequence illustrated.
10
0478 131 8349 A - EN
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 Two-hand operation
During manual mowing, the mowing
blade can only be activated if the OK
button is pressed and held with the
right thumb and the Mow button is
then pressed with the left thumb.
Once activated, only the Mow button must
remain pressed in order to continue
mowing.
5.5 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
comes into contact with a solid obstacle
which has a specific minimum height
(10 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.
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)
5.6 Lifting protection
If the robotic mower is lifted by the hood or
at the carrying handle, mowing is stopped
immediately. The mowing blade comes to
a standstill within a few seconds.
5.7 Tilt sensor
If the permissible slope inclination is
exceeded during operation, the robotic
mower immediately changes its direction
of travel. In the event of a rollover, the
wheel drive and mowing motors are
switched off.
5.8 Display illumination
The display illumination is activated during
operation. Thanks to this illumination, the
robotic mower is easily recognisable, even
in darkness.
5.9 Anti-theft alarm
When the anti-theft alarm is activated, an
alarm signal sounds when the robotic
mower is lifted unless the PIN code is
entered within one minute. (Ö 11.16)
The robotic mower can only be operated in
conjunction with the docking station
supplied. A further docking station must be
linked with the robotic mower. (Ö 11.16)
STIHL recommends that one of the
safety levels "Low", "Medium" or
"High" be set. This ensures that
unauthorised persons cannot
operate the robotic mower using
other docking stations and are
unable to change settings or the
programming.
5.10 GPS protection
The models RMI 632 C, RMI 632 PC are
equipped with a GPS receiver. When GPS
protection is activated, the owner of the
machine is notified if the machine is
operated outside the home area. The PIN
code is also requested on the display.
(Ö 14.5)
Recommendation:
Always activate GPS protection.
(Ö 11.16)

6.3 Warning – dangers caused by
electrical current
Warning:
Risk of electric shock!
Particularly important for
electrical safety are an
intact power cable and
mains plug on the power
supply unit. Damaged cables,
connectors and plugs, or electric
cables that do not conform to
regulations must not be used, to
prevent any risk of electric shocks.
Therefore, check the electric cable
regularly for signs of damage or
ageing (brittleness).
Only use an original power supply unit.
The power supply unit must not be used:
– if it is damaged or worn,
– if the cables are damaged or worn.
Check the power cable in particular for
damage and ageing.
Maintenance and repair work on power
cables and power supply units must only
be performed by specially qualified
technicians.
Danger of electric shock!
Do not connect a damaged cable to the
mains and only touch a damaged cable
once it has been disconnected from the
mains.
The electric cable on the power supply unit
must not be modified (e.g. shortened). The
cable between the power supply unit and
docking station must not be extended.
The power supply unit and cable must not
be left on wet ground for prolonged
periods.
Danger of electric shock!
Damaged cables, connectors and plugs,
or electric cables which do not conform
with regulations may not be used.
Always ensure that the power cables used
are adequately protected by a fuse.
Detach electric cables at the plug and
socket and not by pulling on the electric
cable.
Only connect the machine to a power
supply that is protected by means of a
residual current-operated protective
device with a release current of a
maximum of 30 mA. Your electrician can
provide further information.
If the power supply unit is connected to the
mains supply outside a building, the socket
must be approved for outdoor use. Your
electrician can provide further information
about country-specific legislation.
It must be noted that current fluctuations
can damage the machine when it is
connected to a power generator.
6.4 Battery
Only use genuine batteries.
The battery is intended exclusively for
fixed installation in a STIHL robotic mower.
It is optimally protected there and is
charged when the robotic mower is in the
docking station. No other charger must be
used. The use of an unsuitable charger
can result in danger due to electric shock,
overheating or escaping corrosive battery
fluid.
Never open the battery.
Do not drop the battery.
Never use a defective or deformed battery.
EN
0478 131 8349 A - EN
13
Store the battery out of the reach of
children.
Explosive hazard!
Protect the battery
against direct sunlight,
heat and fire – never
throw it into a fire.
Only use or store the battery at
temperatures from -10°C to max.
+50°C.
Protect the battery against rain
and moisture – do not immerse
in liquids.
Do not subject the battery to
microwaves or high pressure.
Never connect the battery terminals with
metallic objects (short-circuit). The battery
can be damaged through short circuits.
Keep the unused battery away from
metallic objects (e.g. nails, coins,
jewellery). Do not use metallic transport
containers – explosive and fire hazard!
Fluid may escape from the battery due to
improper use – avoid contact! In the case
of inadvertent contact, rinse with water.
Seek medical attention if the fluid contacts
the eyes. Escaping battery fluid can cause
skin irritation and burns.
Do not insert any objects in the ventilation
slots of the battery.
For further safety instructions, see
http://www.stihl.com/safety-data-sheets
6.5 Transporting the machine
Before transporting, and especially before
lifting the robotic mower, activate the
disabling device. (Ö 5.2)
Allow the machine to cool down before
transporting.
Avoid contact with the mowing blade when
lifting and carrying the machine. The
robotic mower must only be lifted at the
carrying handle. Never reach under the
machine.
Take the weight of the machine into
account and use suitable loading aids
(lifters) if required.
Secure the machine and other machine
parts being transported (e.g. docking
station) on the load floor using fastening
materials (straps, ropes, etc.) of an
adequate size at the fastening points
described in this instruction manual.
(Ö 21.)
When transporting the machine, always
observe regional legislation, especially
regarding load security and the transport
of objects on load floors.
Do not leave the battery inside a vehicle
and never expose it to direct sunlight.
Lithium-ion batteries must be treated with
special care during transport. In particular,
short-circuit protection must be ensured.
Transport the battery either in the original
packaging or in the robotic mower.
6.6 Before initial operation
It must be ensured that all persons who
use the machine are familiar with the
instruction manual.
Carefully follow the instructions for
installing the docking station (Ö 9.1) and
perimeter wire (Ö 12.).
The perimeter wire and the power cable
must be securely fastened to the ground
so that they do not present a tripping
hazard. Avoid routing the perimeter wire
and power cable over edges (e.g. edges of
pathways or paving stones). When routing
the perimeter wire and power cable on
ground into which the supplied fixing pins
cannot be driven (e.g. paving stones,
pathways), a cable duct must be used.
Correct routing of the perimeter wire and
power cable must be regularly checked.
To prevent the risk of stumbling, always
drive in the fixing pins all the way.
Do not install the docking station in a place
where it is difficult to see and could
become a tripping hazard (e.g. around the
corner of a house).
If possible, install the docking station out of
the reach of pests such as ants or slugs –
in particular avoid the area around anthills
and composting units.
Areas in which the robotic mower cannot
operate safely (e.g. due to danger of
falling), must be blocked off through
appropriate routing of the perimeter wire.
STIHL recommends that the robotic
mower is only operated on lawns and
surfaced paths (e.g. paved drives).
The robotic mower does not detect any
sudden drops such as edges, steps,
swimming pools or ponds. If the perimeter
wire is routed along potential sudden
drops, a clearance of at least 1m must be
maintained between the perimeter wire
and the danger area for safety reasons.
Regularly inspect the area on which the
machine is to be used and remove any
sticks, stones, wires, bones and all other
foreign objects that could be thrown up by
the machine.
After installing the perimeter wire,
particularly remove all tools from the
14
0478 131 8349 A - EN
mowing area. Broken or damaged fixing
pins must be removed from the lawn and
disposed of.
Regularly check the area to be mown for
uneven areas and level them out.
Never use the machine with damaged
safety devices or with safety devices
removed.
The switch and safety devices installed in
the machine must not be removed or
bypassed.
All faulty, worn or damaged parts must be
replaced before using the machine.
Replace any illegible or damaged danger
signs and warnings on the machine. Your
STIHL specialist has a supply of
replacement stickers and all the other
spare parts.
Before initial operation, it must be ensured
– that the machine is in good operational
condition. This means that the covers
and guards must be in place and in
good condition.
– that the docking station is in a safe
operating condition. Here, all covers
must be properly installed and be in
good condition.
– that the power supply unit has been
connected to a properly installed
socket.
– that the insulation of the electric cable
and the mains plug on the power supply
unit is in good condition.
– that the entire machine (housing, hood,
fastening elements, mowing blade,
blade shaft, etc.) is neither worn nor
damaged.
– that the mowing blade and the blade
fastening are in proper condition
(secure seating, damage, wear).
(Ö 16.3)
– that all screws, bolts, nuts and other
fastening elements are in place and
properly tightened. Tighten any loose
screws, bolts and nuts prior to initial
operation (observe tightening torques).
Carry out any necessary work or consult a
specialist dealer. STIHL recommends
STIHL specialist dealers.
6.7 Programming
Observe local regulations regarding
permitted operating times for gardening
power tools with motors and programme
the active times accordingly. (Ö 14.3)
In particular, programming must also be
adapted so that no children, spectators or
animals are in the area to be mown during
operation.
Changing the programming using the
iMow app in the case of the RMI 632 C,
RMI 632 PC models can result in activities
that will not be expected by other people.
Changes to the mowing plan must
therefore be communicated in advance to
all affected people.
The robotic mower must not operate at the
same time as a sprinkler system. Adapt
the programming accordingly.
Ensure that the correct date and the
correct time are set on the robotic mower.
Correct the settings if necessary. Incorrect
values may cause the robotic mower to
start up unintentionally.
6.8 During operation
Keep other persons, especially
children
and animals, out of the
danger area.
Never allow children to approach or play
with the robotic mower during operation.
Starting a mowing operation using the
iMow app in the case of the RMI 632 C,
RMI 632 PC models may not be expected
by third parties. Affected people must
therefore be notified in advance about
possible activity of the robotic mower.
Never allow the robotic mower to operate
unattended if you know that animals or
persons, particularly children, are in the
vicinity.
When operating the robotic mower in
public places, signs with the following
notice must be affixed around the mowing
area:
"Warning! Automatic lawn mower! Keep
away from the machine! Children must be
supervised!"
Caution – risk of injury!
Never put hands or feet on or
underneath rotating parts.
Never touch the rotating
blade.
Before thunderstorms, or if there is a
danger of lightning strikes, disconnect the
power supply unit from the mains. The
robotic mower must not be operated.
The robotic mower must never be tilted or
lifted when a motor is running.
Never attempt to change settings on the
machine when one of the motors is
running.
EN
0478 131 8349 A - EN
15
For safety reasons, the machine must not
be used on slopes with an inclination of
more than 24° (45 %). Risk of injury!
A slope inclination of 24° corresponds to a
vertical height increase of 45 cm for a
100 cm horizontal distance.
Beware of the cutting tool
running on for several seconds
before coming to a standstill.
Press the STOP button (Ö 5.1)
during running operation:

machine. Always keep your feet a safe
distance from the blade.
To prevent the risk of injury due to slipping,
stumbling, etc., never run when mowing.
Be particularly careful when turning the
robotic mower around or pulling it towards
you backwards.
The risk of accidents is higher if the ground
is damp due to increased danger of
slipping.
Particular caution should be exercised
during working in order to prevent slipping.
If possible, avoid manual mowing when
the ground is damp.
Always ensure good stability on slopes
and avoid mowing on excessively steep
slopes.
Only mow at right-angles to the slope and
never up or down the slope and ensure
that you always stand over the robotic
mower, in order to avoid being run over in
the case of loss of control of the machine.
Objects hidden in the turf (lawn sprinkler
systems, posts, water valves, foundations,
electrical wires, etc.) must be avoided.
Never run over any such foreign objects.
Never steer against obstacles
intentionally. The impact sensor is
disabled during manual mowing.
Do not lean forward and always ensure
that you maintain your balance and a firm
footing on inclines when operating the
machine and its peripherals. Always walk,
do not run.
