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 power supply, which is connected between the
charging station and a 100-240V wall socket.
The power supply 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. Low voltage cables with
3 m and 20 m length are available as optional
accessories.
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 R38Li, R40Li,
R45Li & R50Li). 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 400 m.

2. PRESENTATION
2.3 Function
Capacity
The robotic lawnmower is recommended for lawn sizes
up to the maximum capacity listed in the technical data
section.
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 60 to
80 minutes, depending on the age of the battery and
how thick the grass is. Then the robotic lawnmower will
charge for 50 to 60 minutes. The charging time can
vary depending on, among other factors, the ambient
temperature.
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 power supply 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
.
English - 15
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.
16 - English
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
.
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.
2.4 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

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
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

During installation you will also need:
Hammer/plastic mallet (to simplify putting the
pegs in the ground)
Combination pliers for cutting the boundary
wire and pressing the connectors together.
Polygrip (for pressing the couplers 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.
English - 19
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
3
20 - English
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.
Connecting the power supply
Take the following into consideration when planning
where to place the power supply:
Close to the charging station
Protection from rain
Protection from direct sunlight
If the power supply is connected to an electrical
socket outdoors, this must be approved for outdoor
use.
The low voltage cable for the power supply is 10
metres long, and may not be shortened or extended.
It is not allowed to connect the power supply directly
to the charging station. The low voltage cable must
always be used.
IMPORTANT INFORMATION
The low voltage cable must not under any
circumstances be shortened or extended.
English - 21
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 pegs. The cable must lie
close to the ground so as not to be cut before the
grass roots have grown over it.
The low voltage cable must never be stored in a coil
or under the charging station’s base plate as this can
interfere with the signals from the charging station.
The power supply must be placed where it is well
ventilated and is not exposed to direct sunlight. The
power supply must be placed under a roof.
It is recommended to use an earth fault-breaker when
connecting the power supply to the wall socket.
If the power supply cannot be plugged directly into a
wall outlet, do not under any circumstances mount
the power supply 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 power supply
on the ground.
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
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 pegs.
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 pegs 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 400 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.
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?).
24 - English
3. INSTALLATION
Working area boundaries
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. Ensure that the
tiles are in level with the lawn to avoid excessive
wear on the robotic lawnmower.
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.
Level the lawn and remove holes/hollows in the
working area to avoid pools of water in case of heavy
rain.
Lay the wire up to and around the area to be
demarcated, and then return it back along the same
route. If pegs 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.
0 cm/0"
26 - English
3. INSTALLATION
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 60 cm (90 cm for GARDENA R38Li, 40Li, R45Li,
R50Li). 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. 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.
Secondary

Main area
English - 27
3. INSTALLATION
Passages when mowing
Long and narrow passages and areas narrower than
1.5 - 2 metres should be avoided. When the robotic
lawnmower mows, there is a risk that it travels around
in the passage or area for a period of time. The lawn
will then look flattened.
Slopes
The boundary wire can be laid across a slope that
slants less than 15%.
The boundary wire should not be laid across a slope
that is steeper than 15%. There is a risk that the
robotic lawnmower will find it difficult to turn there.
The mower will then stop and the Outside working
area fault message is displayed. The risk is at its
greatest in damp weather conditions, as the wheels
can slip on the wet grass
However, the boundary wire can be laid across a
slope steeper than 15% if there is an obstacle that
the robotic lawnmower is allowed to collide with, for
example, a fence or a dense hedge.
The robotic lawnmower can
mow lawns that slope up to
25 cm every metre (25%)
inside the working area.
Areas that slope more must
be demarcated by the
boundary wire.
When a part of the working
area's outer edge slopes
more than 15 cm every metre
(15%), the boundary wire
must be laid about 20 cm in
on the flat ground before the
beginning of the slope.
28 - English
3. INSTALLATION
Laying the boundary wire
If you intend to staple down the boundary wire:
Cut the grass very low with a standard
lawnmower or a trimmer where the wire is to be
laid. It will then be easier to lay the wire close to
the ground and the risk of the robotic lawnmower
cutting the wire or damaging the insulation of the
wire is reduced.
Make sure to lay the boundary wire close to the
ground and secure the pegs close together,
approximately 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.
Use a hammer to knock the pegs into the
ground. Exercise care when knocking in the
pegs and make sure the wire is not under strain.
Avoid sharp bends in the wire.
If the boundary wire is to be buried:
Make sure to lay the boundary wire at least 1 cm
and a maximum of 20 cm in the ground. The wire
can be buried for instance using an edge cutter or
a straight spade.
Use the supplied measurement gauge as a guide
when you lay out the boundary wire. This helps you
to easily set the correct distance between the
boundary wire and the boundary/obstacle. The
measurement gauge is broken loose from the box.
Loop for connecting the guide wire
To facilitate the connection of the guide wire to the
boundary wire, it is recommended to create a loop
with about 20 cm of extra boundary wire at the point
where the guide wire will later be connected. It is a
good idea to plan where the guide wire will be placed
before laying out the boundary wire. See
3.6 Installation of the guide wire.
IMPORTANT INFORMATION
Extra wire must not be placed in coils outside
the boundary wire. This can disrupt the
robotic lawnmower.
English - 29
3. INSTALLATION
Laying the boundary wire in towards the charging
station
The boundary wire must be laid in line with the rear
end of the charging station and at least 1.5 metres
straight out to the right and left of the station. See the
illustration. If the boundary wire is laid in any other
way, the robotic lawnmower may find it hard to find
the charging station.
The straight route to the right of the charging station,
in some cases needs to be increased depending on
how the boundary wire is placed in the installation.
Splicing the boundary wire
Use an original coupler if the boundary wire is not
long enough and needs to be spliced. It is waterproof
and gives a reliable electrical connection.
Insert both wire ends in the coupler. Check that the
wires are fully inserted into the coupler so that the
ends are visible through the transparent area on the
other side of the coupler. Now press down the button
on top of the coupler fully. Use a polygrip to
completely press down the button on the coupler.
IMPORTANT INFORMATION
Twinned cables, or a screw terminal block
that is insulated with insulation tape are not
satisfactory splices. Soil moisture will cause
the leads to oxidise and after a while result in
a broken circuit.

3. INSTALLATION
3.5 Connecting the boundary wire
Connect the boundary wire to the charging station:
1. Place the wire ends in the connector:
Open the connector.
Place the wire in the connector grip.
2. Press the connectors together using a pair of
pliers. Press until you hear a click.
3. Cut off any excess boundary wire 1 or 2
centimetres above each connector.
4. Press the connector onto the metal pin, Press
the connector onto the contact pin, marked L
(left) and R (right), on the charging station.
Carefully check that the connector is properly fitted.
IMPORTANT INFORMATION
The boundary wire must not be crossed when
connecting it to the charging station. The
right hand wire end must be connected to the
right hand pin on the charging station and
the left hand wire end to the left pin.
IMPORTANT INFORMATION
The right hand connector must be connected
to the right hand metal pin on the charging
station and the left hand wire end to the left
connector.
English - 31
3. INSTALLATION
3.6 Installation of the guide wire
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. The same cable
roll is used for both the boundary and guide wires.
The guide wire is used by the robotic lawnmower to
find its way back to the charging station but also to
guide the robotic lawnmower to remote areas of the
garden.
To ensure an even cut over the entire lawn, the
robotic lawnmower can follow the guide wire from the
charging station to the guide wire connection in the
boundary wire and start mowing there. Depending on
the garden layout, one should adjust how often the
robotic lawnmower is to follow the guide wire from the
charging station. See 6.6 Settings.
The robotic lawnmower runs at varying distances
from the guide wire to reduce the risk of tracks
forming when the robotic lawnmower follows the
guide wire to and from the charging station. The area
beside the wire which the robotic lawnmower then
uses is called the Corridor.
The robotic lawnmower always runs to the left of the
guide wire as seen facing the charging station. Thus
the corridor is to the left of the guide wire. The
corridor is 50 cm wide. When installing, it is therefore
important to have at least 75 cm free space to the left
of the guide wire and at least 25 cm free space to the
right of the guide wire, as seen facing the charging
station.
It is not allowed to lay the guide wire closer than 30
cm from the boundary wire.
The guide wire, as the boundary wire, can be stapled
to or buried in the ground.
IMPORTANT INFORMATION
Make sure that there is always at least 75 cm
of free space to the left of the guide wire as
seen facing the charging station.
Maximum

3. INSTALLATION
Laying and connecting the guide wire
1. Fasten the guide wire in snap locks at the bottom
of the charging station.
2. Fit the connector to the guide wire in the same
way as for the boundary wire described in
3.5 Connecting the boundary wire. Connect it to
the contact pin on the charging station that is
labelled “Guide”.
3. Run the wire at least 2 metres straight out from
the front edge of the plate.
If the guide wire must be laid in a passage:
The robotic lawnmower follows the guide wire on
the same side of the wire to and from the
charging station. This means that the guide wire
is to the right of the robotic lawnmower when the
mower travels to the charging station while it is to
the left of the mower when the mower travels
away from the charging station.
English - 33
3. INSTALLATION
- In the passage, the guide wire must therefore be
placed so that the robotic lawnmower has as much
space to run in as possible. The distance between
the boundary wire and the guide wire must
however be at least 30 cm.
If the guide wire has to be installed on a steep slope,
it is an advantage to lay the wire at an angle to the
slope. This makes it easier for the robotic lawnmower
to follow the guide wire on the slope.
Avoid laying the wire at sharp angles. This can make
it difficult for the robotic lawnmower to follow the
guide wire.
4. Run the guide wire up to the point on the
boundary wire where a loop to facilitate the
connection of the guide wire was previously
added.
5. Cut the loop on the boundary wire using for
instance a pair of wire cutters.

6. Connect the guide wire to the boundary wire
using a coupler:
Insert the boundary wire in each of the holes in
the coupler. Insert the guide wire in the centre
hole in the coupler. Check that the wires are fully
inserted into the coupler so that the ends are
visible through the transparent area on the other
side of the coupler.
Use a polygrip to completely press down the
button on the coupler.
It does not matter which holes are used to
connect each wire.
7. Staple down/bury the connector in the lawn.
IMPORTANT INFORMATION
The guide wire may not cross the boundary
wire, for instance a boundary wire that is laid
out to an island.
IMPORTANT INFORMATION
Test that the guide wire works using the
Calibrate guide function before using the
robotic lawnmower. See 3.8 First start-up and

3.7 Checking the loop
Check the loop signal by inspecting the indicator
lamp on the charging station.
See 9.2 Indicator lamp in the charging station if the
lamp does not indicate a solid green light.
3.8 First start-up and calibration
Before the robotic lawnmower is operated, a start-up
sequence in the robotic lawnmower's menu must be
carried out as well as an automatic calibration of the
guide signal. The calibration is also a good test to see
that the installation of the guide wire has been done
in such a way that the robotic lawnmower can easily
follow the guide wire from the charging station.
1. Open the control panel cover by pressing the
STOP button.
2. Set the main switch to position 1.
A start-up sequence begins when the robotic
lawnmower is started for the first time. The
following is requested:
Language

Current time
Date format
Date
Four digit PIN code. All combinations except
0000 are permitted.
3. Place the robotic lawnmower in the charging station as requested in the display.
Press the START button and close the cover. The robotic lawnmower will now start
the guide calibration, by leaving the charging station and following the guide wire to
the point where the guide wire is connected to the boundary wire to begin mowing
there. Check that the robotic lawnmower can follow the guide wire all the way.
If it cannot, this may be due to an incorrectly installed guide wire. In this case, check
that the installation is performed as described in 3.6 Installation of the guide wire.
Then carry out a new calibration. See 6.6 Settings.
For R70Li/R80Li, it is also possible to reduce the guide width for the robotic
lawnmower to follow the guide wire through very narrow passages. See
6.4 Installation, R70Li, R80Li. Use the Test OUT function to carry out a new
calibration in the R70Li/R80Li. See 6.4 Installation, R70Li, R80Li.

3.9 Test docking with the charging
station
Before using the robotic lawnmower, check that the
robotic lawnmower can follow the guide wire all the
way to the charging station and easily docks with the
charging station. Perform the test below.
1. Open the control panel cover by pressing the
STOP button.
2. Place the robotic lawnmower close to the point
where the guide wire is connected to the boundary
wire. Place the robotic lawnmower about 2 metres
from the guide wire, facing the guide wire.
3. Select Home mode by pressing the house symbol
key and pressing OK when the cursor is at Home.
Press Start and close the cover.
4. Check that the robotic lawnmower follows the
guide wire all the way to the charging station and
that it docks with the charging station. The test is
approved only if the robotic lawnmower is able to
follow the guide wire the entire distance to the
charging station and docks at the first attempt. If
the robotic lawnmower is unable to dock on the
first attempt, it will automatically try again. The
installation is not approved if the robotic
lawnmower needs two or more attempts to dock
with the charging station. In this case, check that
the charging station, the boundary wire and the
guide wire are installed in accordance with the
instructions in Chapters 3.2, 3.4 and 3.6.
5. The robotic lawnmower will stay in the charging
station until Auto or Man mode is selected. See
5.1 Operation selection.
The guide system must first be calibrated if the above
test is to provide a satisfactory result. See 3.8 First

4.1 Charging a flat battery
When the GARDENA robotic lawnmower is new or has
been stored for a long period, the battery will be flat
and needs to be charged before starting. Charging
takes approximately 80 to 100 minutes.
1. Set the main switch to position 1.
2. Park the robotic lawnmower in the charging
station. Open the cover and slide the robotic
lawnmower in as far as possible to ensure proper
contact between the robotic lawnmower and the
charging station.
3. The display shows a message that charging is in
progress.
WARNING
Read the safety instructions carefully
before you start your robotic
lawnmower.
WARNING
Keep your hands and feet away from
the rotating blades. Never put your
hands or feet close to or under the
body when the motor is running.
WARNING
Never use the robotic lawnmower
when persons, especially children, or
pets, are in the cutting area.
38 - English
4. USE
4.2 Using the timer
Use the timer function (see 6.3 Timer.) to avoid a
downtrodden lawn. When setting the timer, calculate
that the robotic lawnmower mows about the listed
amount of the number of square meters per hour and
day listed in table Work capacity.
Example
If the working area is 360 m
2
in size, R70Li must
operate for 8 hours a day. The times are
approximate and depend for instance on grass
quality, blade sharpness and battery age.
The factory setting for the timer is 07:00-23:00
(07:00-22:00 for the GARDENA
R38Li,R40Li,R45Li,R50Li) and it allows mowing
every day of the week. This setting is suitable for the
listed maximum working area.
If the size of the working area allows it, the quality of
the grass can be further improved if it is cut every
other day instead of a few hours every day. In
addition, the grass benefits from resting completely
during at least a three-day period once a month.
Standby
The robotic lawnmower has an inbuilt standby period
according to the Standby time table. The standby
period provides for instance a good opportunity to
water or play games on the lawn.
Example 1
The times used in this example are applicable to
GARDENA R40Li, but the principle is the same
for the other models.
Work period 1: 07:00 - 22:00
Work days: All days
The factory setting ensures that the robotic
lawnmower begins cutting the lawn at 07.00. The
mower is parked in the charging station from
19.00 and rests until it starts cutting again at
07.00.
If the timer setting is divided into two work
periods, the standby period can be divided into a
number of periods. The minimum standby period
time must however be a according to the
Standby time table.
IMPORTANT INFORMATION
Use the timer to avoid mowing when there
are usually children, pets and anything else
that could be damaged by the rotating blades
on the lawn.

5.1 Operation selection
The operation selection button is symbolised by a
house. When the button has been pressed, the
selected operation mode is shown in the display. By
consecutively pressing the button many times, one
can choose between three different operation modes.
1. HOME:
Sends the robotic lawnmower to the charging
station. It remains here until another operation
mode is selected. The text Home is shown in the
operation window. When the battery is fully
charged, the robotic lawnmower will remain
parked in the charging station. The robotic
lawnmower will first leave the charging station
and begin mowing again when the operation
selection is altered to AUTO.
The Home setting is also used after a new
installation or when changes are made to an
existing installation to test if the robotic
lawnmower can follow the guide wire and dock
with the charging station. See 3.9 Test docking
with the charging station.
2. AUTO:
The standard, automatic operation mode where
the robotic lawnmower mows and charges
automatically.
3. MAN:
When mowing secondary areas (see
3.4 Installation of the boundary wire), the MAN
setting must be used.
If MAN is selected and the robotic lawnmower
starts when it is out on the lawn, it will mow until
the battery runs out. It will then stop and the
Needs manual charging” message will appear.
The robotic lawnmower must then be moved
manually to the charging station and then started
manually after charging.
If the robotic lawnmower charges in the MAN
mode, it will fully charge, move about 20 cm out
of the charging station and then stop. This
indicates that it is charged and ready to start

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.

6. MENU FUNCTIONS
6.3 Timer
The lawn should not be cut too often to obtain the
best mowing result. Consequently, it is important to
limit the operating time using the timer function if the
working area is less than the robotic lawnmower's
working capacity. When the robotic lawnmower is
allowed to mow too much, the lawn may appear
flattened. Besides, the robotic lawnmower is
subjected to unnecessary wear.
The timer function is also an ideal means to control
which work hours the robotic lawnmower should not
mow, for example, when the children are playing in
the garden.
The factory setting is 07:00 - 23:00 (07:00-22:00 for
GARDENA R38Li, R40Li, R45Li, R50Li) and it allows
mowing every day of the week. This setting is suitable
for the listed maximum working area.
When setting the timer, calculate that the robotic
lawnmower mows about the listed amount of the
number of square meters per hour and day listed in
table Work capacity.
The table below provides suggestions for different
timer settings depending on garden size. The table can
be used to set the operating time. The times should be
seen as indicative, they may need to be adjusted to
suit the garden. Use the table as follows:
1.Find a work area that closest matches the garden's
area.
2.Select an appropriate amount of work days per week
(for some work areas 7 days may be needed).
3.Work hours per day shows how many hours a day
the robotic lawnmower will be allowed to work for the
selected amount of work days.
4.Suggested time interval shows a time interval that
corresponds to the required work hours per day.

6. MENU FUNCTIONS
to mow due to a timer setting.
The robotic lawnmower has an inbuilt standby period
of about 8 hours a day (12 hours for the GARDENA
R38Li, R 40Li, R45Li. R50Li). The robotic lawnmower
is parked in the charging station during this period. See
4.2 Using the timer.
6.4 Installation, R70Li, R80Li
The following operating settings are available via this
selection in the main menu.
Guide width
to select the distance from the guide wire the
robotic lawnmower is allowed to travel when it
follows this to and from the charging station.
Remote start 1
to control the robotic lawnmower so that it can
easier reach remote parts of the garden.
Remote start 2
to control the robotic lawnmower so that it can
easier reach remote parts of the garden.
Test settings
to check the above settings.
Drive past wire
to set the distance over the boundary wire that
the robotic lawnmower should travel before
turning back.
For examples of garden settings, see 7. Garden
examples.
Guide width
The guide width is a measure of how far from the
guide wire the robotic lawnmower is allowed to travel
when it follows this to and from the charging station.
The area beside the wire which the robotic
lawnmower then uses is called the Corridor.
The robotic lawnmower has a default setting for
medium wide corridors. To further reduce the risk of
tracks forming, it is recommended to select a wide
corridor in working areas where it is possible to do so.
IMPORTANT INFORMATION
Always use as wide a guide width as
possible. The Narrow setting must only be
used when none of the other settings can be
used in the working area in question.

6. MENU FUNCTIONS
Wide
In a wide corridor, the robotic lawnmower mows at
more varied distances from the guide wire.
A garden that is open and free of narrow passages
should have a wide corridor to minimise the risk of
tracks forming.
Medium
In a medium wide corridor, the robotic lawnmower
travels close to and far away from the guide wire, but
not as far away from the guide wire as is the case
when a wide corridor is selected.
In a medium wide corridor, the robotic lawnmower
travels close to and far away from the guide wire, but
not as far away from the guide wire as is the case
when a wide corridor is selected.
Narrow
With a narrow corridor, the robotic lawnmower runs
straight over the guide wire.
The Narrow corridor setting is not normally
recommended, but in a garden with one or many
narrow passages, a narrow corridor may be the only
option. The Narrow corridor setting increases the risk
for tracks forming along the guide wire.
Remote start 1
One important function with the guide wire is the
capacity to steer the robotic lawnmower to remote
garden areas when required. This function is very
useful in gardens where, for instance, the front and
back are joined by a narrow passage.
With this function activated, (any option other than
Never is selected) the robotic lawnmower will at times
follow the guide wire from the charging station to the
remote area and begin mowing there.
IMPORTANT INFORMATION
The distance the robotic lawnmower
maintains from the guide wire varies
depending on the layout of the working area.
Use the Test IN function to ensure that the
wide corridor setting can be used in the
garden in question.
52 - English
6. MENU FUNCTIONS
Proportion
How often the robotic lawnmower must follow the
guide wire from the charging station is selected
as a proportion of the total number of times it
leaves the charging station. At all other times,
the robotic lawnmower leaves the charging
station in the standard manner and starts to
mow.
The following five options can be selected;
- Never (0%)
- Rarely (approx. 20%)
- Medium (approx. 50%)
- Often (approx. 80%)
- Always (100%)
Select the percentage that corresponds to the size
of the remote area relative to the total working
area. If the remote area is for instance less than
half of the total working area, then Rarely must be
selected. If the remote area is for instance half of
the total working area, Medium must be selected.
Compare with the examples in 7. Garden
examples.
The default setting is Rarely.
Distance
Enter the distance in metres along the guide wire
from the charging station to the remote area
where the robotic lawnmower begins mowing.
Tips! Use the Test OUT function to determine how
far it is to the remote area. The distance, stated in
metres, will be shown in the robotic lawnmower's
display.
Remote start 2
If the working area contains two remote areas, the
guide wire should be installed so that it reaches both
areas. Remote start 1 and Remote start 2 can then
be combined to steer the robotic lawnmower to each
area.
The settings for Proportion and Distance are carried
out in the same way as for Remote start 1.
The default setting is Never.
Take into account that the total figure for Proportion
cannot exceed 100%. If one has for instance selected
Often for Remote start 1, then one can only select
Never or Rarely for Remote start 2.
Guide width is the same for Remote start 1 and
Remote start 2. In this way, it is the narrowest passage
along the guide wire that limits the maximum guide
width.

6. MENU FUNCTIONS
Test settings
In the Test settings menu, it is possible to test the
settings for Remote start 1 and Remote start 2 and
that the selected Guide width works in the working
area in question.
Test OUT
The Test OUT function is used to test if the selected
Guide width suits the installation in question and to
calculate the distance from the charging station to a
remote area.
To test the settings in Remote start 1:
Park the robotic lawnmower in the charging station
and select Test OUT - Remote start 1. The robotic
lawnmower will then leave the charging station straight
away along the guide wire and begin mowing after the
designated distance.
If there is a passage that the robotic lawnmower
cannot get through, the settings in Guide width ought
to be changed from Wide to Medium. If required, the
setting can also be changed to Narrow. The Narrow
guide width setting should only be used if none of the
other settings work for this installation. When the Test
OUT function is activated, the robotic lawnmower
travels the farthest distance from the wire allowed by
the selected guide width.
The figure here shows how the robotic lawnmower
travels through a passage when Guide width is set to
Medium and not to Wide.
How to measure the distance from the charging
station to a remote area:
Enter a distance which beyond any doubt exceeds the real
figure. The maximum distance that can be entered is 100
metres. Park the robotic lawnmower in the charging station
and select Test OUT. The robotic lawnmower will immediately
leave the charging station. The distance, stated in metres, will
be shown in the mower display as the robotic lawnmower
operates. Stop the robotic lawnmower at the required position
and note the distance. Enter the displayed number of metres in
the Distance field for the working area in question.
If Remote start 2 has been activated, i.e. if another option
other than Never has been selected for Proportion, these
settings must also be tested. Remote start 2 test is performed
in the same way as for Remote start 1.

8. MAINTENANCE
8.2 After winter storage
Check if cleaning is needed, particularly the charging
strips on both the robotic lawnmower and the charging
station, on the first time of use. If the charging strips
appear to be burnt or coated, clean them using a fine
grade emery cloth. Check also that the robotic
lawnmower’s time and date are correct.
8.3 Cleaning
It is important to keep the robotic lawnmower clean.
A mower with large amounts of grass stuck to it will not
cope as well with slopes. It is recommended to clean
using a brush.
Chassis and blade disc
1. Set the main switch in position 0.
2. Wear protective gloves.
3. Lift the robotic lawnmower onto its side.
4. Clean the blade disc and chassis using e.g. a
dish brush.
At the same time, check that the blade disc
rotates freely in relation to the foot guard.
If long blades of grass or other objects find their
way in, these may impede the blade disc. Even a
slight braking effect leads to a higher
consumption of energy and longer mowing
times, and at worst will prevent the robotic
lawnmower from being able to mow a large lawn.
Chassis
Clean the underside of the chassis. Brush or wipe
with a damp cloth.
Wheels
Clean around the front wheels and rear wheel as well
as the rear wheel bracket.
IMPORTANT INFORMATION
Never use a high-pressure washer or even
running water to clean the robotic
lawnmower. Never use solvents for cleaning.
