PRESENTATION

Presentation

Congratulations on your choice of an exceptionally

high quality product.

To get the best from your Auto Mower requires knowl-

edge of its function. This chapter contains information

you should be aware of when planning the installation.

Installation of the Husqvarna Auto Mower includes four

main components:

Auto Mower

, an automatic lawn mower that mows the

lawn by moving in essentially an irregular pattern. The

mower is powered by a maintenance free battery

Charging station

, where your Auto Mower 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 out signals so the Auto Mower ﬁnds the

charging station.

• To charge the Auto Mower battery.

Transformer

, which is connected between the charg-

ing station and a 230 V wall socket. The transformer is

connected to the wall socket via an integrated power

cord and to the charging station via a 20 m long low

voltage cable. The length of the low voltage cable must

not be changed.

Boundary wire

, laid in a loop around the Auto Mower’s

working area. The wire is laid around the edges of the

lawn and around objects and plants that the mower

must not run into.

The length of boundary wire needed in an installation

is the circumference of the working area plus a few

extra metres to lay around ”islands”, objects and

plants. A few extra metres are also required for any

subsequent adjustments. The boundary wire supplied

for the installation is 250 m long. If this is not sufﬁcient

more wire can be purchased, with a connector, and

spliced onto the existing wire.

PRESENTATION

Function Auto Mower

Working method

The Auto Mower automatically mows the lawn. It con-

tinuously combines mowing and charging.

When the Auto Mower works on a lawn, it simulta-

neously stores information about how the garden is

shaped.

The charging station sends out a signal that the Auto

Mower can sense at a distance of 6 - 8 metres. The

mower starts to seek out the charging station when the

capacity of the battery becomes too low. The Auto

Mower does not mow when it is searching for the

charging station.

When the battery is charged the mower reverses, turns

around and leaves the charging station in a randomly

selected direction within the exit sector 90°-270°. Both

the reversing length and exit direction can be set, see

”3. Installation” on page 32.

When the Auto Mower body hits an obstacle, the

mower reverses and selects a new direction.

Two sensors, front and back on the Auto Mower, sense

when the mower approaches the boundary wire. The

Auto Mower overruns the wire by up to 27 centimetres

before it turns. The overrun length can be set, see

”Drive past wire (3-2)” on page 34.

PRESENTATION

The STOP button on the top of Auto Mower 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.

The control panel on the top of the Auto Mower is

where you manage all the mower settings. The main

switch is also located on the control panel. Open the

control panel cover by pressing down the STOP button.

When the main switch is turned ON for the ﬁrst time, a

start-up sequence begins which includes: selection of

the language, time format, date format and the four

digit PIN code as well as the setting of the time and

date, see page 25.

The Auto Mower can enter a sleep mode to save

power. The display on the control panel is then com-

pletely dimmed.

The sleep mode is activated 25 minutes after the

STOP button has been pressed and then not reset to

the operating mode. Auto Mower is then activated by

switching the main switch off and on.

The sleep mode can also be activated in the event of a

fault occurring during mowing or charging and which is

not rectiﬁed within 25 minutes. The Auto Mower is then

activated by pressing the STOP button.

PRESENTATION

Movement pattern

The mower’s movement pattern is irregular and is

determined by the Auto Mower itself. A movement pat-

tern is never repeated. This mowing system means the

lawn is mown equally without any mowing lines.

If the Auto Mower enters an area where it senses the

grass is longer than earlier, it can change the move-

ment pattern. It can then mow in a square pattern to

cover the area of longer grass more systematically.

Thereafter the mower returns to the irregular move-

ment pattern.

Capacity

The Auto Mower is recommended for lawns up to

1800 m

2

.

Auto Mower mows about 75 m

2

per hour. How large an

area is mown depends primarily on the condition of the

blades and the type of grass, growth rate and humidity.

The shape of the garden is also signiﬁcant. If the gar-

den mainly consists of open lawns, the Auto Mower

can mow more per hour than if the garden consists of

several small lawns separated by many trees, ﬂower

beds and passages.

How long the Auto Mower mows respective charges

can vary depending on, among others, the ambient

temperature. Up to about 25°C a fully charged Auto

Mower mows for approximately 60 - 90 minutes,

depending on the age of the battery and the thickness

of the grass. The mower then charges for about 60

minutes. Above 25°C both the mowing and charging

times gradually drop.

B. Planning the installation

Charging station

First and foremost the charging station should be posi-

tioned:

• Centrally in the main area, along the outer edge

and with a large free area in front of the station.

• In the shadow. The battery is spared if it charged in

the low possible ambient temperature.

• On relatively level ground. The height difference

must not differ more than 10 cm between the front

and rear of the charging station.

• Close to a wall socket:

The charging station should be connected to a

230 V wall socket via the low voltage cable and

transformer.

The supplied low voltage cable is 20 metres long.

The transformer must be placed where it is well

ventilated and is not exposed to direct sunlight. It is

also beneﬁcial if the transformer can be placed

under a roof.

It is recommended to use an earth fault-breaker

when connecting the transformer to the wall socket.

INSTALLATION

Plan the position of the charging station according to

the shape of your garden.

The Auto Mower can be set for one of three basic gar-

den shapes (see page 34).

The Auto Mower works differently depending on the

garden shape the mower has been set to.

The available garden shapes are: open, complex 1 and

complex 2.

The following pictures are examples of the different

garden shapes. The pictures are also good examples

of appropriate charging station placement.

• The open shape represents a lawn area with few

obstacles and no passages.

• Complex 1 is a large lawn area with an average

amount of obstacles and passages.

INSTALLATION

• Complex 2 is a large lawn area with many obstacles

and passages.

Do not put the charging station in a corner or pocket in

the working area.

If the garden consists of two large lawns joined by a

passage, it may be difﬁcult for the Auto Mower to ﬁnd

the entrance to the passage. Making it difﬁcult to work

efﬁciently in both areas. One way to make the mower

effectively reach both areas is to position the charging

station in the middle of the passage.

When the charging station needs to be placed in a

passage, is it appropriate to manually set the exit

direction, see ”Charge exit settings (3-1)” on page 32.

This will ensure both areas are mown equally and the

grass close to the charging station will not appear

down trodden.

INSTALLATION

Boundary wire

For a successful installation the placement of the

boundary wire should be planned carefully. Planning is

simpliﬁed if you make a sketch of the working area,

including all obstacles. Draw how the boundary wire

should be routed on the sketch.

The boundary wire should be laid so it:

• Forms a loop around the working area for the Auto

Mower. Only Husqvarna boundary wire ought to be

used. This is tinned and has a high quality insulation

to withstand the dampness in the ground.

• Is a maximum of 500 metres long.

• Maintains a maximum distance of 35 metres from

Auto Mower in the entire working area.

• Does not lie on a sharp incline. The Auto Mower

may ﬁnd it difﬁcult to reverse back, especially in

damp weather conditions, when there is a large risk

of skidding.

Include the possibility in the planning that adjustments

may need to be made to the loop. In doing so remem-

ber:

• Leave a few extra metres of wire at the beginning

and end, close to the charging station.

• Place a few extra metres of wire about every 30

metres around the entire loop.

All extra wire should be laid in tight, parallel loops If

staples are used, the parallel loops should be

placed under the same staple.

3012-138

IMPORTANT INFORMATION

Extra wire must not be placed in coils outside

the boundary wire. This can disrupt the Auto

Mower.

3012-281

English-

19

INSTALLATION

Remember the following with regard to the working

area boundaries:

• If a high obstacle, for example a wall or fence, bor-

ders the working area, the boundary wire should be

laid 35 cm from the obstacle. This will prevent the

Auto Mower from colliding with the obstacle and

reduce body wear.

• If the working area borders against, for example,

pools of water the boundary wire should be supple-

mented with a fence or the like. The height must

then be at least 10 cm. This will prevent the Auto

Mower, under any circumstances, coming outside

of the working area.

• 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 30 cm inside the working area. This prevents

the wheels from driving into the ditch or up onto the

verge.

• If the working area borders against a ﬂat path or the

like that lies level with the lawn, is it possible to

allow the Auto Mower to run a little over the path.

The boundary wire should then be laid 10 cm from

the edge of the path.

INSTALLATION

Remeber the following with regard to the working area

boundaries:

• The Auto Mower can mow areas with a gradient of

up to 1: 3 (33 cm/m) inside the working area. Areas

that slope more must be demarcated by the bound-

ary wire. If any part of the working area’s outer edge

has a gradient of 1: 5 (20 cm/m) or more, the wire

should be laid inside where the slope starts. The

Auto Mower may ﬁnd it difﬁcult to turn at the loop

where the ground slopes heavily.

• Use the boundary wire to demarcate areas inside

the working area, for example, ﬂower beds and

fountains. Lay the cable up to the area, around it

and then return along the same route. If staples are

used, the cable should be laid under the same sta-

ple on the return route.

• Obstacles that can withstand a collision, for exam-

ple, trees or bushes higher than 10 cm, do not need

to be demarcated by the boundary wire. The Auto

Mower will turn when it collides with this type of

obstacle.

However, for the most gentle and silent operation, it

is preferable to demarcatee all ﬁxed objects in and

around the working area.

• Obstacles that slope slightly, for example, stones or

large trees with raised roots, should be demarcated

or removed. The Auto Mower can slide up onto this

kind of obstacle causing the blades to be damaged.

Remember the following with regard to secondary

areas and passages:

• If there are secondary areas close to the main area

the boundary wire should be laid so that these

areas form an ”island” outside of the main area.

Secondary areas are working areas without the

charging station, but which are encircled by the

same boundary wire as the main area. The Auto

Mower must be moved manually between the main

and secondary areas.

If the garden consists of two areas where one area

is much smaller than the other and the areas are

only connected by a very long narrow passage, it

may be suitable to create a secondary area.

English-21

INSTALLATION

• In order for the loop system to work well, the wires

in passages where the Auto Mower is to run

through must not lie too close together.

A passage should be at least 2 metres wide so the

Auto Mower can ﬁnd it and make its way through it.

The minimum spacing between the wires in a pas-

sage is 130 cm.

The transition between a large area and a passage

should be, if possible, designed like a ”funnel”, with

rounded corners, to make it easier for the Auto Mower

to enter the passage.

C. Placing the charging station

1. Place the charging station according to your plan.

2. Connect the low voltage cable to the charging sta-

tion.

Only Husqvarna original cable and transformer

may be used.

3. Connect the low voltage cable to the transformer.

The connectors may be a slightly difﬁcult to con-

nect, as they are moisture-proof.

4. Connect the transformer’s power cord to a 230V

wall socket. It is preferable to use an earth-fault

breaker as recommended.
