2. PRESENTATION
2. Presentation
This chapter contains information that is important to
be aware of when planning the installation.
An installation of GARDENA R40Li includes four main
components:
• R40Li, a robotic lawn mower that mows the lawn
by essentially operating in a random pattern. The
mower is powered by a maintenance-free
battery. The mower is powered by a
maintenance-free battery.
• Charging station, where your R40Li 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.
• Sending control signals in the guide wire so
that R40Lican find the charging station.
• To charge R40Li battery.
• 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.
• Wire, laid in a loop around R40Li working area.
The boundary wire is laid around the edges of
the lawn and around objects and plants that the
mower must not run into. The wire is also used
as the guide wire.
10 - English
The wire supplied with the installation is 150 m
long. If this is not sufficient more wire can be
purchased, with a connector, and spliced onto
the existing wire.
The maximum permitted length for the loop wire
is 250 m.

2. PRESENTATION
2.2 Function
Capacity
R40Li is recommended for lawns up to 400 m
How big an area R40Li 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,
R40Li can mow more per hour than if the garden
consists of several small lawns separated by trees,
flower beds and passages.
A fully charged R40Li mows for 30 to 70 minutes,
depending on the age of the battery and how thick the
grass is. Then the mower will charge for approx. 80 to
100 minutes. The charging time can vary depending
on, among other factors, the ambient temperature.

in size.
Mowing technique
The mowing system used by R40Li is based on an
effective and energy efficient principle. Unlike normal
robotic lawn mowers, R40Li cuts the grass instead of
striking it off.
We recommend you allow R40Li to mainly mow in dry
weather to obtain the best possible result. R40Li can
even mow in the rain, however, wet grass easily
collects on the mower and the risk of slipping on
steep slopes is greater.
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 53.
12 - English
2. PRESENTATION
Working method
The R40Li automatically mows the lawn.
It continuously combines mowing and charging.
The mower starts to search for the charging station
when the battery charge becomes too low. R40Li
does not mow when it is searching for the charging
station.
When R40Li 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 mower leaves
the charging station and starts mowing in a randomly
selected direction within the 90˚ to 270˚ exit sector.
To ensure an even cut, even in inaccessible parts of
the garden, the lawn mower 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 R40Li body hits an obstacle, the mower
reverses and selects a new direction.
Two sensors, one at the front and one at the back on
R40Li, sense when the mower approaches the
boundary wire. The R40Li overruns the wire by up to
28 centimetres before it turns back.
The STOP button on the top of R40Li is mainly used
to stop the mower when it’s running. When the STOP
button is pressed a cover opens, behind which there
is a control panel. The STOP button remains
depressed until the cover is closed again. This acts
as start inhibitor.
English - 13
2. PRESENTATION
The control panel on the top of R40Li is where you
manage all the mower settings. Open the control
panel cover by pressing down the STOP button.
When the main switch is turned to 1 for the first time,
a start-up sequence begins which includes the
selection of the language, time format, date format
and four-digit PIN code as well as setting of the time
and date. See 3.8 First start-up and calibration for
setting the main switch to position 1. See 6.4 Security
(2) on page 42 for more information on theft
protection.

The mower’s movement pattern is irregular and is
determined by R40Li itself. A movement pattern is
never repeated. This mowing system means the lawn
is mown equally without any mowing lines.
2.3 Search method
R40Li runs irregularly until it reaches the guide wire.
The mower then follows the guide wire in to the
charging station.
The guide wire is a cable 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

3. INSTALLATION
3. Installation
This chapter describes how you install the GARDENA
R40Li. Before starting the installation read the previous
chapter 2. Presentation.
Read also through this entire chapter before beginning
the installation. How the installation is made also
affects how well R40Li will work. 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.
In chapter 7. Garden example , there are examples of
installations.
Visit also www.gardena.com/int 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 R40Li.
3.1 Preparations
1. If the lawn in the proposed working area is taller
than 10 cm, mow it using a normal lawn mower.
Then collect the clippings.
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 detail
diagram 2.1 What’s what? .
• Operator’s Manual (24)
• R40Li
• Charging station (6)
• Loop wire for the boundary wire and guide wire (16)
English - 15
3. INSTALLATION
• Transformer (20)
• Low voltage cable (17)
• Staples (21)
• Connector for the loop wire (18)
• Screws for the charging station (19)
• Measurement gauge (22)
• Solderless coupler 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 units together.
• Edge cutter/straight spade if the boundary wire
must be buried.
3.2 Installation of the charging
station
Ideal position of 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.
• Close to a wall socket. The supplied low
voltage cable is 10 metres long.
• 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
• Any aesthetic preferences
For examples of where best to install the charging
station, see 7. Garden example on page 47.
16 - English
3. INSTALLATION
The charging station must be positioned with a great
deal of free area in front of it (at least 3 metres). It
should also be centrally placed in the working area so
that R40Li finds it easier 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 lawn mower 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 so that
its plate bends.
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 lawn
mower 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 picture opposite. Read more
about islands in the chapter 3.4 Installation of the
boundary wire .
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 to the transformer is 10 meters
long, and may not be shortened or extended.
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.
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.
For best performance, the transformer must not be
exposed to direct sunlight.
IMPORTANT INFORMATION
The low voltage cable must not be shortened
nor extended.
IMPORTANT INFORMATION
Place the low voltage cable so that the blades
on the blade disc can never come in contact
with it.
18 - English
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
wall socket outdoors, it 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.
1
IMPORTANT INFORMATION
It is not permitted to make new holes in the
plate. Only the existing holes may be used to
secure the plate to the ground.
IMPORTANT INFORMATION
Do not tread or walk on the charging station
plate.
3.3 Charging the battery
As soon as the charging station is connected, it is
possible to charge the mower.
The mower can be charged as soon as the charging
station is connected. Set the main switch to the
position.
Place R40Li 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
R40Li cannot be used before the installation
is complete.
English - 19
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 cable can be buried using for instance 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 it:
• Forms a loop around the working area for the R40Li. Only GARDENA boundary wire must be used.
It is specially designed to resist dampness from the soil that could otherwise easily damage the
wires.
• The mower is never more than 15 metres from the wire at any point in the entire working area.
• The wire is no more than 250 metres long.
• 20 cm of extra wire is available to which the guide wire will be connected to later. See 3.6 Installation
of the guide wire on page 27.
Depending on what the working area is adjacent to, the boundary wire must be at 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’s what? on page 11 ).
20 - English
3. INSTALLATION
Boundaries for the working area
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
R40Li 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 against a small ditch, for
example, a flower bed or a small elevation, e.g. a low
verge (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
verge.
About 12 cm of grass along the ditch/stone edging
will not be mown.
If the working area borders against a flat path or the
like that lies level with the lawn, it is possible to allow
R40Li 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 pavement will be
cut.
When the working area is divided by a flat slab path
that is level with the lawn, it is possible to allow R40Li
to run over the path. It can be an advantage to lay the
boundary wire under the slabs. The boundary wire
can also be laid in the joint between the slabs.
Note! The R40Li 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 a fence or the like. The height must then
be at least 15 cm. This will prevent R40Li
from ending up outside the working area
under any circumstances.
