2. PRESENTATION
2. Presentation
This chapter contains information that is important to
be aware of when planning the installation.
An installation of Husqvarna Automower
®
305 includes
four main components:
• Automower
®
305, an robotic 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 Automower
®
305
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 Automower
®
305 can find the charging
station.
• To charge Automower
®
305 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 nor extended. A longer low voltage
cable is available as option. Please contact your
dealer for more information.
• Wire, laid in a loop around Automower
®
305
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.
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.

2. PRESENTATION
2.2 Function
Capacity
Automower
®
305 is recommended for lawns up to 500
m
2
in size.
How big an area Automower
®
305 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, Automower
®
305 can mow
more per hour than if the garden consists of several
small lawns separated by trees, flower beds and
passages.
How long Automower
®
305 mows and recharges can
vary depending on, among others, the ambient
temperature. A fully charged Automower
®
305 mows
for 40 to 50 minutes, depending on the age of the
battery and how thick the grass is. The mower then
charges for 120 to 150 minutes depending on the age
of the battery and the ambient temperature.
Mowing technique
The mowing system used by Automower
®
305 is based
on an effective and energy efficient principle. Unlike
normal robotic lawn mowers, Automower
®
305 cuts the
grass instead of striking it off.
We recommend you allow Automower
®
305 to mainly
mow in dry weather to obtain the best possible result.
Automower
®
305 can even mow in the rain, however,
wet grass easily collects on the mower and the risk of
slipping on steep slopes is greater.
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.

English - 13
2. PRESENTATION
Working method
Automower
®
305 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.
Automower
®
305 does not mow when it is searching
for the charging station.
When Automower
®
305 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.
In order to ensure an even cut, even in parts of the
garden that are hard to reach, there are a number of
manual settings for how the mower is to leave the
charging station, see 6.4 Installation (2) .
When Automower
®
305 body hits an obstacle, the
mower reverses and selects a new direction.
Two sensors, one at the front and one at the back on
Automower
®
305, sense when the mower
approaches the boundary wire. Automower
®
305
overruns the wire by up to 28 centimetres before it
turns.
The STOP button on the top of Automower
®
305 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.

14 - English
2. PRESENTATION
The control panel on the top of Automower
®
305 is
where you manage all the mower 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 Linking Automower® 305 to the charging station
After this, the selected PIN code must be entered
every time the main switch is set to 1 . See 6.5
Security for more information on theft protection.
Movement pattern
The mower’s movement pattern is irregular and is
determined by Automower
®305 itself. A movement
pattern is never repeated. This mowing system
means the lawn is mown equally without any mowing
lines.
2.3 Search method
Automower®305 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 Husqvarna
Automower
®
305. 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 Automower
®
305 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.
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 installation.
3.8 Linking Automower® 305 to 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 Automower
®
305. If however the mower has
to be started without the entire loop installation in
place, a shorter temporary boundary wire and guide
wire can be connected to the charging station.
3.1 Preparations
1. If the lawn in the proposed working area is taller
than 10 cm, mow it using a normal robotic 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)
• Automower
®
305
• Charging station (6)
• Loop wire for the boundary wire and guide wire
(16)

16 - English
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: A hammer to
knock the staples into the ground, combination pliers,
and a straight spade if the boundary wire is to be
buried.
3.2 Installation of the charging
station
Ideal position of the charging station
For examples of where best to install the charging
station, See 7. Garden example.
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 Automower®305 finds it easier to reach all areas
in the working area.
It is a good idea to place the charging station in the
shadow. The battery is spared if it is charged in the
lowest possible ambient temperature.
Do not put the charging station in a corner or pocket
in the working area. There must be a straight
boundary wire, at least 2 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.
3

English - 17
3. INSTALLATION
The charging station must not be positioned so that
its plate bends.
Consider the distance to a wall socket when selecting
a location for the charging station. The charging
station must be connected to a 230 V wall socket via
the transformer. The low voltage cable for the
transformer is 10 metres long but other lengths are
available as option. Please contact your dealer for
more information.
Tip! It is possible to let the low voltage cable cross the
working area. It must then be either stapled down or
buried. In some cases there is a better positioning
option for the charging station than close to a house
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.
Avoid placing the charging station in a narrow
passage (narrower than about 3 metres).
IMPORTANT INFORMATION
The low voltage cable must not be shortened
nor extended.

18 - English
3. INSTALLATION
Installation and connecting the charging
station
1. Position the charging station in a suitable spot.
2. Attach the charging station to the ground using
the supplied screws.
3. Ensure the screws are secured all the way down
in the countersink.
4. Connect the low voltage cable to the charging
station.
5. Connect the transformer’s power cord to a 230V
wall socket. If the wall socket is outdoors, it is
important that the transformer is protected from
direct sunlight.
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
1position.
Place Automower®305 in the charging station to
charge the battery while the boundary and guide
wires are being laid.
If the battery is empty, it takes around 3 hours to fully
charge it.
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
The transformer may not be exposed to direct
sunlight.
IMPORTANT INFORMATION
Do not tread or walk on the charging station
plate.
IMPORTANT INFORMATION
Automower®305 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.
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.
Best position for the boundary wire
The boundary wire should be laid so it:
• Forms a loop around the working area for Automower®305. Only an original boundary wire must be
used. This is tinned and has a high quality insulation to withstand the dampness in the ground.
Maintains a maximum distance of 15 metres from Automower®305 in the entire working area.
Is a maximum of 250 metres long.
The boundary wire is laid at different distances from obstacles depending on what the working area
borders. The picture below shows how the boundary wire should be routed around the working area
and around obstacles.

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
Automower®305 from colliding with the obstacle and
reduce body wear.
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.
If the working area borders against a flat path or the
like that lies level with the lawn, it is possible to allow
Automower®305 to run a little over the path. The
boundary wire should then be laid 5 cm from the edge
of the path.
When the working area is divided by a flat slab path
that is level with the lawn, it is possible to allow
Automower®305 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! Automower®305 must never run over a gravel
path or similar material, which can damage the
blades.
IMPORTANT INFORMATION
If the working area is adjacent to water
bodies, slopes or precipices, the boundary
wire should be supplemented with a fence or
the like. The height must then be at least 15
cm. This will prevent Automower®305 from
ending up outside the working area under
any circumstances.
