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 100-240V 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 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 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.

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 67.

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.

1157069-26,R40Li_GB.book Page 15 Wednesday, November 19, 2014 5:02 PM

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 on page 34.

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

on page 34.

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 59 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?.

• Robotic lawnmower

• Charging station (6)

• Loop wire for boundary wire and guide

wire (16)

• Transformer (20)

1157069-26,R40Li_GB.book Page 17 Wednesday, November 19, 2014 5:02 PM

18 - English

3. INSTALLATION

• 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 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 on page 59.

1157069-26,R40Li_GB.book Page 18 Wednesday, November 19, 2014 5:02 PM

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.

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 23.

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.
