1Introduction
Thank you for your purchase. The information contained in
this manual will help you receive maximum performance and
satisfaction from your STIHL robotic mower and, if followed,
reduce the risk of injury from its use.
IMPORTANT
READ CAREFULLY BEFORE USE
KEEP FOR FUTURE REFERENCE
Because a robotic mower is a high-speed cutting
tool, designed for operation independent from
the active control o r supervision of a n operator ,
special safety precautions must be observed to
reduce the risk of personal injury.
Read this instruction manual thoroughly before
setting up your robotic mower and periodically
thereafter. Follow all safety precautions.
Careless or improper use of the robotic mower
can cause serious or fatal injury.
This robotic mower has a GPS receiver and can also
connect to the Internet over a cellular network, allowing the
operator to track mowing activity and modify certain settings
using the STIHL iMOW® U.S. mobile and web apps
("iMOW® App").
Discuss setup and operation of your robotic mower with your
authorized STIHL iMOW® servicing dealer. STIHL
recommends having an authorized STIHL iMOW® servicing
dealer set up your robotic mower.
Before the robotic mower can connect to the Internet, the
unit must be unlocked by an authorized STIHL iMOW®
dealer. The dealer can also guide you through the
registration and activation process.
Do not lend or rent your robotic mower without this
instruction manual. Allow only persons who fully understand
the information in this manual to set up, operate or maintain
the robotic mower. The operator must be familiar with the
robotic mower's controls before starting work. The operator
is responsible for accidents or hazards occurring to other
people or their property.
For further information, or if you do not understand any of
the instructions in this manual, please refer to the iMOW®
App, go to www.stihlusa.com or contact your authorized
STIHL iMOW® servicing dealer.

11 Installing the Perimeter Wire
English
When installing the perimeter wire:
► Use only perimeter wire and wire stakes authorized by
STIHL.
► Install the perimeter wire in a continuous loop around the
entire mowing area with a maximum length of 1640 ft.
(500 m).
► If the total length of the perimeter wire is less than 262 ft.
(80 m), the STIHL Small Area Module AKM 100 (special
accessory) must also be installed, @ 10.4. For more
information, contact your authorized STIHL iMOW®
servicing dealer.
► Maintain the specified wire clearances specified below.
Measure the clearances using the iMOW® Ruler,
@ 11.3.
– Patios and paths with a maximum height difference
between lawn area of +/- 0.4 in. (1 cm): 0 in. (0 cm)
– Corridors: 11 in. (27 cm)
– High obstacles (e.g. walls, fences, trees): 13 in. (33 cm)
– Narrow passages: 21.3 in. (54 cm)
– Swimming pools, ponds and falling edges: 3.3 ft. (1 m)
► Avoid creating angles less than 90°. These will be difficult
for the robotic mower to navigate, and could result in
unmowed areas.
A
B
► Mowing areas must not overlap. Keep a minimum
distance of a ≥ 3.3 ft. (1 m) between the perimeter wires
of the two mowing areas of neighbor A and neighbor B.
► Install reserve lengths of perimeter wire at regular
intervals near difficult passages. Doing so make it easier
to modify the installation of the perimeter wire or docking
station if that should become necessary.
► If burying the perimeter wire, place it at a depth of no more
than 3.9 in. (10 cm).
Burying the perimeter wire in the ground may influence
signal reception, particularly if flagstones or paving stones
are laid over the perimeter wire. The robotic mower may
then travel along at a greater offset to the perimeter wire,
requiring more space in corridors, confined areas and when
traveling along edges. Adjust the location and depth of the
perimeter wire if necessary.
NOTICE
Avoid contacting the perimeter wire when de-thatching or
aerating the lawn. Also use caution when operating a line
trimmer near the perimeter wire. De-thatching, aerating and
trimming operations can result in a cut or damaged
perimeter wire. Refer to your sketch of the mowing area and
take special care to avoid the perimeter wire when
performing these operations.
11.2 Making a Sketch of the Mowing Area
STIHL recommends making a sketch of the mowing area
that includes the following:

obstacles, borders and any restricted areas which the
robotic mower must not mow, @ 26.
– The location and position of the docking station, @ 10.3.
– The location of the perimeter wire and any wire
connectors you have installed, @ 10.4.
– If you change the dimensions of your mowing area after
the initial setup (by adding sections or moving the
perimeter wire, for example), re-link the iMOW® to the

11.4 Measuring Wire Clearances at Corners
11.5 Routing the Perimeter Wire in Confined Areas
The robotic mower can travel automatically though narrow
passages, provided the minimum wire clearances are
maintained.
► If you route the wire between obstacles higher than 0.4 in.
(1 cm), e.g. walls or hedges, keep a minimum wire
clearance of one length of the iMOW® Ruler (b = 13 in.
(33 cm)).
► If you route the wire between obstacles lower than 0.4 in.
(1 cm), e.g. paths or patios, keep a minimum wire
clearance of c = 21.3 in. (54 cm).
► Route the perimeter wire to block off narrower areas in
which a < 47.2 in. (120 cm).
► If you route the perimeter wire in a confined area,
deactivate the passage function (offset drive home),
@ 15.3 or install a search loop, @ 11.9.
In tapered corners (45° - 90°) the perimeter wire should be
installed as shown. The two angles must be at least one
length of the iMOW® Ruler (a = 13 in. (33 cm)) apart so that
the robot mower can drive down the edge.
Do not include corners less than 45° into the installation of
the perimeter wire.

11.6 Routing Around Restricted Areas
A restricted area is an area that the robotic mower must
avoid, including obstacles that cannot be mowed or objects
that the mower can't bump off of to change direction, such
as flower beds, trees with buttressed roots, etc.
► Install a restricted area around such obstacles.
41
English
11 Installing the Perimeter Wire
► To ensure a robust operation, install restricted areas in a
round shape - no oval, angular or inwardly curved shapes.
► Maintain the wire clearance a = 13 in. (33 cm) around the
obstacle (2) to prevent the robotic mower from scraping
against the obstacle (2).
► Install the perimeter wire (1) with the aid of the
iMOW® Ruler (3) as illustrated.
► The diameter of any restricted area must be at least 26 in.
(66 cm) and no more than 9.8 ft. (3 m).
► Keep a minimum clearance of b = 21.3 in. (54 cm)
between the perimeter wire routed around a restricted
area and the perimeter wire at the edge of the mowing
area.
► Keep a minimum clearance of at least c = 6.6 ft. (2 m)
around the docking station (1).
► Route the perimeter wire from the edge to the obstacle
with the proper clearance.
► Route the perimeter wire around the obstacle (2) and
attach it to the ground using a sufficient number of wire
stakes (3). Observe the installation direction (arrows).
► Then route the perimeter wire back to the edge. The
segment of perimeter wire routed back to the edge (4)
must be laid directly next to the segment leading to the
restricted area. Keep the segments parallel. When the
wire is laid side-by-side, the signal is canceled and the
iMOW® will mow directly over this section of perimeter
wire. If the wires are separated, however, the iMOW® will
not traverse the wire and the area between the two
segments of perimeter wire will not be mowed.
► After routing the perimeter wire back to the edge, do not
cross the sections of the perimeter wire. Continue the
installation around the perimeter of the mowing area. The
perimeter wire must exit the restricted area in the direction
opposite to the direction in which it entered the restricted
area, @ 11.10.

11.7 Installing Linked Areas and Secondary Areas
Linked areas (B) and secondary areas (C) are parts of the
mowing area that are not located in the primary mowing
area (A) where the docking station (1) is located.
A secondary area is an area that iMOW® cannot physically
drive to. It cannot be mowed automatically. The robotic
mower must be picked up and carried to the secondary area
and brought back to the primary area when mowing is
complete.
Linked areas (B) can only be mowed automatically if they
are linked by corridors or linking sections.
► Route the perimeter wire (2) in the same direction in all
linked areas and secondary areas.
► Connect the linked areas to the primary mowing area by
installing corridors (@ 11.8) or linking
sections (@ 11.10). Never cross perimeter wires in the
linking areas. Keep them parallel.
► Activate secondary areas in the "Settings – Installation"
menu, @ 15.3.
11.8 Installing Corridors
A corridor joins a linked area to the primary mowing area,
e.g. a mowing area in front of and behind the house. This
allows both mowing areas to be mowed automatically.
In corridors, the lawn is only mowed along the path of the
perimeter wire. In order for the iMOW® to mow the linked
area, a starting point in the linked area must be defined,
@ 15.6.
The wire spacing and the STIHL Corridor Pattern are
matched to the installation of the perimeter wire on the lawn
surface. If the perimeter wire is buried very deeply, e.g.
under stone paving, the dimensions differ. Check the
function and adjust the wire installation if necessary.
In corridors, the lawn is only mowed along the path of the
perimeter wire.
To install a corridor:
► Remove stones, pieces of metal, glass, wire or other
objects that could be thrown or flung by the cutting
attachment.
► Keep a minimum clearance between obstacles higher
than 0.4 in. (1 cm) of a = 42.5 in. (108 cm).
► Keep a minimum clearance between obstacles lower than
0.4 in. (1 cm), paths/obstacles that can be travelled on, of
b = 11 in. (27 cm).
► The total length of a corridor, including entrance and exit,
must be at least f = 30.1 in. (84 cm).
► Route the perimeter wire (1) parallel to the ground and
attach it to the ground with a sufficient number of wire
stakes (2).

14.5 Mowing Plan
Mowing Plan Theory of Operation
Before changing your mowing plan, read the following
section carefully.
During the initial setup, the iMOW® will automatically
calculate an appropriate automatic mowing plan. That plan
consists of active times and a weekly mowing duration.
Active times are those windows of time in which the iMOW®
is programmed to mow automatically. The iMOW® will only
mow in automatic mode during the active times. The mowing
duration is the total number of hours the iMOW® will mow
per week.
Satisfactory cutting results depend on the iMOW® having
sufficient mowing duration and sufficient active times to
complete the mowing operation for the entire lawn. In the
"Dynamic" mowing plan setting, automatic mowing will
cease once the iMOW® has reached its total allotted
mowing duration for the week, even if there are remaining
active times scheduled. In the "Standard" mowing plan
setting, the iMOW® will operate throughout all active times.
Mowing operations will only be interrupted by charging
operations.
The active times and mowing duration must be set properly
to ensure that a sufficient number of mowing hours are set
each week (mowing duration) and that the iMOW® has
sufficient windows of time (active times) to complete the
mowing.
54
[SNR_Complete]
14 Menu Functions
If you increase the mowing duration, be sure to expand the
active times as well to accommodate the increased number
of mowing hours. The total weekly active time must be
higher than the total weekly mowing duration in order to
account for charging time and to provide a buffer in case
active times are missed due to rainfall.
The status screen displays the remaining mowing duration
for the week and the next scheduled active time.
Mowing Plan Menu
Automatic mowing
On - Automatic mowing is switched on. The robotic mower
will operate at the next active time.
Off - All active times are disabled.
Pause today - The robotic mower pauses until the next day.
This option is only available if there are active times left
during the current day.
Mowing duration
The total weekly mowing hours can be adjusted.
This option is only available in the “Dynamic“ mowing plan
setting.
Active times

English
The rectangular blocks displayed in black beneath the days
of the week represent the saved active times. When
automatic mowing is turned on, mowing operations take
place only during active times. The iMOW® will not mow
during all active times as the iMOW® may return to the
docking station if it starts raining or the iMOW® requires
charging.
Blocks displayed in grey represent active times without
mowing operations, e.g. where the active time has been
deactivated by the operator. When automatic mowing is
turned off, the entire mowing plan is deactivated and all
active times are shown in grey.
► Select an active time by pressing the navigation pad
downwards, upwards, left or right.
► Open the settings by pressing the OK button, @ 14.6.

approach or play with the robotic mower. Keep children and
pets away from the mower while it is in operation. Never
allow the robotic mower to operate if you know that animals
or persons are or may be in the mowing area or vicinity.
Next to every active time, a symbol shows the current status
of the active time:
This symbol indicates that the active time is
activated. The robotic mower will mow automatically
according to the mowing plan.
This symbol indicates that the active time is
deactivated. The robotic mower will not mow during

22.3 Searching for a Wire Break
The LED on the docking station flashes red when there is a
break in the perimeter wire.
The wire break search can be performed either with the
control panel / manual controller removed or inserted.
The following instructions describe how to search for a wire
break in a clockwise direction, i.e. if the perimeter wire is
followed in a clockwise direction when facing the charging
contacts of the docking station. The search can also be
performed in a counterclockwise direction if necessary.
However, if you search in a counterclockwise direction, you
must disconnect the right perimeter wire end.
WARNING
To reduce the risk of electric shock, always unplug the
power supply from the electrical socket before removing the
cover of the docking station.
To find a wire break:
► Press the ON/OFF/Home button on the docking station
one time to activate the search for a wire break. The LED
on the docking station will continue to flash red, while in
