MEMO
Product registration key:
The Product Registration Key is a valuable document and must be stored in a safe place. This key is
necessary for example to register the product on GARDENA's website or to unlock the robotic lawnmower
in the event of a lost PIN code. The product registration key is provided in a separate document in the
product packaging.
If the robotic lawnmower is stolen, it is important to notify GARDENA of this. Contact GARDENA Central
Service and provide the robotic lawnmower's serial number and product registration key so that it can be
registered as stolen in an international database. This is an important step in the robotic lawnmower's theft
protection which reduces interest in the buying and selling of stolen mowers.

2. PRESENTATION
2. Presentation
This chapter contains information that is important to
be aware of when planning the installation.
Installation of the robotic lawnmower involves four
main components:
• A robotic lawnmower that mows the lawn by
essentially operating in a random pattern. The
robotic lawnmower is powered by a
maintenance-free battery.
• A charging station, to where the robotic
lawnmower returns when the charge level in the
battery becomes too low.
The charging station has three functions:
• To send control signals along the boundary
wire.
• To send control signals in the guide wire so
that the robotic lawnmower can find the
charging station.
• To charge the robotic lawnmower battery.
• A transformer, which is connected between the
charging station and a 230V wall socket. The
transformer is connected to the wall socket and
to the charging station using a 10 m long low
voltage cable. The low voltage cable must not be
shortened or extended. A 20 meter low voltage
cable is available to purchase as an accessory.
Contact GARDENA Central Service for more
information.
• Loop wire, laid in a loop around the robotic
lawnmower’s working area. The loop wire is laid
around the edges of the lawn and around objects
and plants that the robotic lawnmower must not
run into. The loop wire is used both as a
boundary wire and a guide wire.
The loop wire supplied for the installation is 200
m long (150 m for the GARDENA R40Li). If it is
not long enough, more loop wire can be
purchased and spliced onto the existing loop
wire with an original coupler.
The maximum permitted length for the loop wire
is 250 m.

2.2 Function
Capacity
2. PRESENTATION
The robotic lawnmower is recommended for lawns up
to 700 m
How big an area the robotic lawnmower can keep cut
depends primarily on the condition of the blades and
the type, growth and moisture of the grass. The shape
of the garden is also significant. If the garden mainly
consists of open lawns, the robotic lawnmower can
mow more in one hour than if the garden consists of
several small lawns separated by many trees, flower
beds and passages.
A fully charged robotic lawnmower mows for 40 to
60 minutes, depending on the age of the battery and
how thick the grass is. Then the robotic lawnmower will
charge for 60 to 90 minutes. The charging time can
vary depending on, among other factors, the ambient
temperature.
2
in size (400 m

for the R40Li).
Mowing technique
The robotic lawnmower's mowing system is based on
an efficient and energy saving principle. Unlike many
standard lawnmowers, the robotic lawnmower cuts
the grass instead of knocking it off.
It is recommended to allow the robotic lawnmower to
mainly mow in dry weather to obtain the best possible
result. The robotic lawnmower can also mow in the
rain, however, wet grass easily sticks on the robotic
lawnmower and there is a greater risk of slipping on
steep slopes.
If there is risk for thunder, the transformer should be
disconnected from the power and the boundary wire
and the guide wire from the charging station.
The blades must be in good condition to obtain the
best mowing result. In order to keep the blades sharp
for as long as possible it is important to keep the lawn
free from branches, small stones and other objects.
Replace the blades regularly for the best mowing
result. It is very easy to replace the blades. See
8.6 Replacing the blades on page 60.
12 - English
2. PRESENTATION
Working method
The robotic lawnmower automatically mows the lawn.
It continuously alternates between mowing and
charging.
The robotic lawnmower starts to search for the
charging station when the battery charge becomes
too low. The robotic lawnmower does not mow when
it is searching for the charging station.
When the robotic lawnmower searches for the
charging station, it first searches irregularly for the
guide wire. Then it follows the guide wire to the
charging station, turns around just in front of the
station and backs into it.
When the battery is fully charged, the robotic
lawnmower leaves the charging station in a randomly
selected direction within the 90˚-270˚ exit sector.
To ensure an even cut, even in inaccessible parts of
the garden, the robotic lawnmower can follow the
guide wire out from the charging station to where the
guide wire connects to the boundary wire to begin
mowing there.
When the robotic lawnmower body hits an obstacle,
the robotic lawnmower reverses and selects a new
direction.
Two sensors, one on the front and one on the back of
the robotic lawnmower, will sense when the robotic
lawnmower is approaching the boundary wire. The
robotic lawnmower overruns the wire by up to
28 centimetres before it turns back.
The STOP button on the top of the robotic
lawnmower is mainly used to stop the robotic
lawnmower when it’s running. When the STOP button
is pressed a cover opens, behind which there is a
control panel. The STOP button remains pressed in
until the cover is closed again. This acts as a start
inhibitor.
English - 13
2. PRESENTATION
The control panel on the top of the robotic
lawnmower is where you manage all the robotic
lawnmower settings. Open the control panel cover by
pressing down the STOP button.
When the main switch is set to position 1 for the first
time, a start-up sequence begins which includes
language selection, time format, date format and the
four-digit PIN code and setting the time and date. See
3.8 First start-up and calibration on page 32.
Movement pattern
The robotic lawnmower’s movement pattern is
irregular and is determined by the robotic lawnmower
itself. A movement pattern is never repeated. With
the mowing system the lawn is mown equally without
any mowing lines from the robotic lawnmower.

2.3 Search method
The robotic lawnmower runs irregularly until it reaches
the guide wire. Then the robotic lawnmower follows the
guide wire to the charging station.
The guide wire is a wire that is laid from the charging
station towards, for instance, a remote part of the
working area or through a narrow passage to be then
connected with the boundary wire. For more
information, see 3.6 Installation of the guide wire
on page 32.

3. INSTALLATION
3. Installation
This chapter describes how you install the GARDENA
robotic lawnmower. Before starting the installation
read the previous chapter 2. Presentation .
Read also through this entire chapter before beginning
the installation. How the installation is done also
affects how well the robotic lawnmower works. It is
therefore important to plan the installation carefully.
Planning is simplified if you make a sketch of the
working area, including all obstacles. This makes it
easier to see the ideal positions for the charging
station, the boundary wire and the guide wire. Draw on
the sketch where the boundary and guide wires should
be routed.
See 7. Garden examples on page 54 for installation
examples.
Visit also www.gardena.com for further descriptions
and tips regarding installation.
Carry out the installation in the following steps:
3.1 Preparations.
3.2 Installation of the charging station.
3.3 Charging the battery.
3.4 Installation of the boundary wire.
3.5 Connecting the boundary wire.
3.6 Installation of the guide wire
3.7 Checking the loop.
3.8 First start-up and calibration
3.9 Test docking with the charging station
The charging station and boundary and guide wires
must be connected to be able to carry out a complete
start-up of the robotic lawnmower.
3.1 Preparations
1. If the lawn in the working area is longer than
10 cm, mow it using a standard lawnmower.
Then collect the grass.
2. Read carefully through all the steps before the
installation.
3. Check that all parts for the installation are
included. The numbers in brackets refer to the
component illustration 2.1 What is what? .
• Operator's Manual (25)
• Robotic lawnmower
• Charging station (6)
• Loop wire for boundary wire and guide wire (16)

3. INSTALLATION
• Transformer (20)
• Low voltage cable (17)
• Staples (21)
• Connector for connecting the loop wire to the
charging station(18)
• Screws for the charging station (19)
• Measurement gauge (22)
• Couplers for the loop wire (23)
During installation you will also need:
• Hammer/plastic mallet (to simplify putting the
staples in the ground)
• Combination pliers for cutting the boundary
wire and pressing the contact strips together.
• Edge cutter/straight spade if the boundary wire
must be buried.
3.2 Installation of the charging
station
Ideal position for the charging station
Take the following aspects into consideration when
identifying the best location for the charging station:
• Allow for 3 metres of free space in front of the
charging station
• It must be possible to lay at least 1.5 metres of
boundary wire straight out to the right and left
of the charging station
• It must be close to a wall socket The supplied
low voltage cable is 10 metres long. A 20
meter low voltage cable is available to
purchase as an accessory. Contact GARDENA
Central Service for more information.
• A level surface to place the charging station on
• Protection from water spray for instance from
irrigation
• Protection from direct sunlight
• Place in the lower part of a working area that
has a major slope
• Possible requirement to keep the charging
station out of sight for outsiders
For an example of an ideal position of the charging
station, see 7. Garden examples on page 54.
16 - English
3. INSTALLATION
The charging station must be positioned with a great
deal of free space in front of it (at least 3 metres). It
should also be centrally placed in the working area to
make it easier for the robotic lawnmower to reach all
areas in the working area.
Do not put the charging station in confined spaces in
the working area. There must be a straight boundary
wire, at least 1.5 metres long, to the right and left of
the charging station. The wire must be laid straight
out from the rear end of the charging station. Any
other locations can mean that the robotic lawnmower
enters the charging station sideways and will have
difficulty docking.
Do not put the charging station in a corner in the
working area. There must be a straight boundary
wire, at least 1.5 metres long, to the right and left of
the charging station.
The charging station must be positioned on relatively
level ground. The front end of the charging station
must be a maximum of 3 cm higher than the back
end. The front end of the charging station must never
be lower than the back end.
The charging station must not be positioned in a way
that can bend its base plate.
3020-043

English - 17
3. INSTALLATION
If the installation is done in a working area with a
steep slope (such as around a house on a hill), the
charging station should be placed in the area at the
bottom of the slope. This makes it easier for the
robotic lawnmower to follow the guide wire to the
charging station.
The charging station should not be placed on an
island as this limits the laying of the guide wire in an
optimal way. If the charging station has to be installed
on an island, the guide wire also has to be connected
to the island. See the illustration opposite. Read more
about islands in chapter 3.4 Installation of the
boundary wire on page 21.
Connecting the transformer
Take the following into consideration when planning
where to place the transformer:
• Close to the charging station
• Protection from rain
• Protection from direct sunlight
If the transformer is connected to an electrical socket
outdoors, this must be approved for outdoor use.
The low voltage cable for the transformer is 10
metres long, and may not be shortened or extended.
18 - English
3. INSTALLATION
It is possible to let the low voltage cable cross the
working area. The low voltage cable must be stapled
down or buried, and the cutting height should be such
that the blades on the blade disc can never come in
contact with the low voltage cable.
Make sure the low voltage cable is laid along the
ground and secured with staples 75 cm apart. The
cable must lie close to the ground so as not to be cut
before the grass roots have grown over it.
The transformer must be placed where it is well
ventilated and is not exposed to direct sunlight. The
transformer must be placed under a roof.
It is recommended to use an earth fault-breaker when
connecting the transformer to the wall socket.
The transformer must be mounted on a vertical
surface, such as a wall or a fence. Screw the
transformer in place using the two mounting eyelets.
No screws are supplied. Select screws suitable for
the material in question.
Do not, under any circumstances, mount the
transformer at a height where there is a risk it can be
submerged in water (at least 30 cm from the ground).
It is not permitted to place the transformer on the
ground.
IMPORTANT INFORMATION
The low voltage cable must not under any
circumstances be shortened or extended.
IMPORTANT INFORMATION
Place the low voltage cable so that the blades
on the blade disc can never come in contact
with it.
IMPORTANT INFORMATION
Use the plug to disconnect the charging
station, for instance before cleaning or
repairing the loop wire.

3. INSTALLATION
Installation and connecting the charging
station
1. Position the charging station in a suitable spot.
2. Connect the low voltage cable to the charging
station.
3. Connect the transformer’s power cable to a 230V
wall socket. If the transformer is connected to an
electrical socket outdoors, this must be approved
for outdoor use.
4. Attach the charging station to the ground using
the supplied screws. Ensure the screws are
screwed all the way down in the countersink.
IMPORTANT INFORMATION
It is not permitted to make new holes in the
base plate Only the existing holes may be
used to secure the base plate to the ground.
IMPORTANT INFORMATION
Do not tread or walk on the charging station's
base plate.
3.3 Charging the battery
As soon as the charging station is connected, it is
possible to charge the robotic lawnmower. Set the
main switch to position 1 .
Place the robotic lawnmower in the charging station
to charge the battery while the boundary and guide
wires are being laid.
If the battery is flat, it takes around 80 to 100 minutes
to fully charge it.
IMPORTANT INFORMATION
The robotic lawnmower cannot be used
before the installation is complete.
20 - English
3. INSTALLATION
3.4 Installation of the boundary wire
The boundary wire can be installed in one of the following ways:
1. Securing the wire to the ground with staples.
It is preferable to staple down the boundary wire if you want to make adjustments to the boundary wire
during the first few weeks of operation. After a few weeks the grass will have grown over the wire making it
no longer visible. Use a hammer/plastic mallet and the staples supplied when carrying out the installation.
2. Bury the wire.
It is preferable to bury the boundary wire if you want to dethatch or aerate the lawn. If necessary, both
methods can be combined so one part of the boundary wire is stapled down and the remainder is
buried. The wire can be buried for instance using an edge cutter or a straight spade. Make sure to lay
the boundary wire at least 1 cm and a maximum of 20 cm in the ground.
Best position for the boundary wire
The boundary wire must be laid so that:
• A loop is formed around the working area for the robotic lawnmower. Only original boundary wire
must be used. It is specially designed to resist dampness from the soil that could otherwise easily
damage the wires.
• The robotic lawnmower is never more than 15 metres from the wire at any point in the entire working
area.
• The total length of the boundary wire does not exceed 250 metres.
• 20 cm of extra wire is available to which the guide wire will be connected later. See 3.6 Installation of
the guide wire on page 28.
Depending on what the working area is adjacent to, the boundary wire must be laid at different distances
from obstacles. The illustration below shows how the boundary wire must be laid around the working area
and around obstacles. Use the supplied measurement gauge to obtain the correct distance (see 2.1 What
is what? on page11).

If a high obstacle, for example a wall or fence,
borders the working area, the boundary wire should
be laid 30 cm from the obstacle. This will prevent the
robotic lawnmower from colliding with the obstacle
and reduce body wear.
About 20 cm around the fixed obstacle will not be
mown.
If the working area borders on a small ditch, for
example a flower bed or a small elevation, or a low
curbstone (3-5 cm), the boundary wire should be laid
20 cm inside the working area. This prevents the
wheels from driving into the ditch or up onto the
curbstone.
About 12 cm of grass along the ditch/curbstone will
not be mown.
If the working area borders on a paving stone path or
similar which is level with the lawn, it is possible to
allow the robotic lawnmower to run a little over the
path. The boundary wire should then be laid 5 cm
from the edge of the path.
All the grass along the side of the paving stone path
will be cut.
When the working area is divided by a paving stone
path which is level with the lawn, it is possible to allow
the robotic lawnmower to run over the path. It can be
an advantage to lay the boundary wire under the
paving stones. The boundary wire can also be laid in
the joint between the paving stones.
Note: The robotic lawnmower must never run over
gravel, mulch or similar material which can damage
the blades.
IMPORTANT INFORMATION
If the working area is adjacent to water
bodies, slopes, precipices or a public road,
the boundary wire must be supplemented
with an edging or the like. It must then be at
least 15 cm in height. This will prevent the
robotic lawnmower from ending up outside
the working area under any circumstances.

3. INSTALLATION
Boundaries within the working area
Use the boundary wire to demarcate areas inside the
working area by creating islands around obstacles
which cannot withstand a collision, for example,
flowerbeds, bushes and fountains.
Obstacles that can withstand a collision, for example,
trees and bushes higher than 15 cm, do not need to
be demarcated by the boundary wire. The robotic
lawnmower will turn around when it collides with this
type of obstacle.
To achieve careful and silent operation, it is
recommended to isolate all fixed objects in and
around the working area.
Lay the wire up to and around the area to be
demarcated, and then return it back along the same
route. If staples are used, the wire should be laid
under the same staple on the return route. When the
boundary wires to and from the island are laid close
together, the robotic lawnmower can drive over the
wire.
The boundary wire may not be crossed on its way to
and from an island.
Obstacles that slope slightly, for example, stones or
large trees with raised roots, must be isolated with an
island or removed. Otherwise the robotic lawnmower
can slide up onto this kind of obstacle causing the
blades to be damaged and/or the mower to get stuck.
Secondary areas
If the working area consists of two areas which the
robotic lawnmower has difficulty travelling between, it
is recommended to set up a secondary area.
Instances of this are 25% slopes or a passage that is
narrower than 150 cm. Lay the boundary wire then
around the secondary area so that it forms an island
outside of the main area.
The robotic lawnmower must be moved manually
between the main and secondary area when the lawn
in the secondary area has to be cut. The MAN
operation mode must be used as the robotic
lawnmower cannot travel on its own from the
secondary area to the charging station. See
5.1 Operation selection on page 39. In this mode,
the robotic lawnmower will never look for the
charging station but will mow until the battery runs
out. When the battery is flat, the robotic lawnmower
will stop and the Needs manual charging message
will appear in the display. Then place the robotic
lawnmower in the charging station to charge the
battery. If the main working area has to be cut after
charging, it is appropriate to switch the operation
mode to Auto before placing the robotic lawnmower
in the charging station.
