The concept behind the Automower comes straight out of nature -
Please read this Operator’s Manual carefully before using the machine.
the principle of the grazing animal. Which means basically that the grass is cut a little and often. This is not only more efficient, it’s better for the grass too.

This chapter contains information you should be aware of when planning the installation.
An installation of Automower from Husqvarna™ includes four main components:
Automower, 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 Automower 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 Automower finds the charging station.
To charge the Automower battery.
3012-691
Transformer, which is connected between the charging station and a 120V wall socket. The transformer is connected to the wall socket via an integrated power cord and to the charging station via a 66 ft long low voltage cable. The low voltage cable must not be extended.
Boundary wire, laid in a loop around the Automower’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 boundary wire supplied for the installation is 820 ft long. If this is not sufficient more wire can be purchased, with a connector, and spliced onto the existing wire.

2.2 Function of Automower
Capacity
The Automower is recommended for lawns up to
0.5 acre.
Automower mows about 800 ft 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 garden mainly consists of open lawns, the Automower can mow more per hour than if the garden consists of several small lawns separated by trees, flower beds and passages.
How long the Automower mows and recharges can vary depending on, among others, the ambient temperature. Up to about 77 °F a fully charged Automower mows for approximately 40 - 60 minutes, depending on the age of the battery and the thickness of the grass. The mower then charges for about 45 minutes. Above 77 °F both the mowing and charging times gradually drop.

per hour. How large an
Mowing technique
The mowing system used by Automower is based on an effective and energy efficient principle. Unlike normal lawn mowers, Automower cuts the grass instead of striking it off.
We recommend you allow the Automower to mainly mow in dry weather to obtain the best possible result. Automower can even mow in the rain, however, wet grass easily collects on the mower and the risk of slipping on steep slopes is greater.
When there is a risk of thunder the Automower should not stand in the charging station. The 24 V connector should also be removed.
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.
3012-422
12 Automower from
Working method
The Automower automatically mows the lawn. It continuously combines mowing and charging.
The charging station sends out a signal that the Automower can sense at a distance of 20 - 23 ft. The mower starts to search for the charging station when the battery charge becomes too low. The Automower does not mow when it is searching for the charging station.
When Automower searches for the charging station it uses one or more of three different search methods: Irregular, Follow loop in and Follow guide wire. For more information about the search methods, see 2.3 Search method on page 15 and Follow loop in (3-2-2) on page 55.
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°.
To make it easier for the Automower to reach all parts of the garden you can manually set how the mower will leave the charging station, see 6.5 Garden (3) on page 51.
2. Presentation
3012-510
When the Automower body hits an obstacle, the mower reverses and selects a new direction.
Two sensors, at the front and back on the Automower, sense when the mower approaches the boundary wire. The Automower overruns the wire by up to 27 centimeters (11") before it turns. The overrun length can be set, see
Drive past wire (3-4-2)
on page 59.
3012-511
3012-693

2. Presentation
The STOP button on the top of Automower 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 Automower 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 four digit PIN code, plus setting of the time and date, see page 34.
The selected PIN code must then be entered each time the main switch is moved to the ON position. This theft-prevention function is called Time lock (4-1-2) and Automower has this function activated as a default setting. The function also means that the mower stops mowing after a set number of days and will not continue until the correct PIN code has been entered. The function can be deactivated or changed as required. For more information about Time lock (4-1-2), see page 60.
The Automower can enter a sleep mode to save power. The display on the control panel is then completely dimmed.
The sleep mode is activated 25 minutes after the STOP button has been pressed and then not reset to the operating mode. Automower 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 Automower is then activated by pressing the STOP button.

Movement pattern
The mower’s movement pattern is irregular and is determined by the Automower itself. A movement pattern is never repeated. This mowing system means the lawn is mown equally without any mowing lines.
If the Automower enters an area where it senses the grass is longer than earlier, it can change the movement 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 movement pattern.
When Automower mows in a square pattern, this is known as square mode cutting. The main switch must be set to ON and the mower must have been operational for about 13 - 14 hours in order for Automower to start square mode cutting.

2.3 Search method
Automower can be set to search for the charging station in three different ways. Using the setting options the three search methods can be combined to optimize the search for the charging station. The required search method or methods depends on the shape of the garden.
Search method 1: Irregular
Automower runs irregularly until it finds the charging station.
This search method is best for an installation that has an open lawn and no narrow passages (narrower than about 10 ft).
The advantage of this search method is that there is no risk of leaving tracks in the grass after the mower.
The disadvantage is that the search times can be somewhat longer.
3012-483
Automower from 15
2. Presentation
Search method 2: Follow loop in
Automower runs irregularly until it reaches the boundary wire. The mower then follows the boundary wire in to the charging station.
This search method is best for an installation that has an open lawn with wide passages (wider than about 10 ft) and no, or only a small, island.
The advantage of this search method is that the search times are generally short.
The disadvantage is that tracks can be formed to a certain extent in the grass behind the mower. Problems can also arise if there are narrow passages or a large number of islands, for example, bushes. Automower may need to drive round an island up to 2 - 3 times, before it realizes that it is an island and drives on.
Search method 3: Follow guide wire
Automower runs irregularly until it reaches the guide wire. The mower then follows the guide wire in to the charging station.
The guide wire is an extra wire that is laid from the charging station, out towards a remote part of the working area or through a narrow passage and is then connected to the boundary wire. For more information, see 3.8 Installation of the guide wire on page 34.
This search method is best for an installation that has numerous or large islands, narrow passages or steep slopes.
The advantage of this search method is that the search times are generally short.
The disadvantage is that the mower can leave tracks in the grass along the length of the guide wire.

2.4 More than one Automower in a garden
If you install more than one Automower in the same area of lawn, each mower must have its own PIN code. However, if the boundary wires are laid at least 16" from each other the mowers can have the same PIN code. This will mean that about 8" between the working areas will not be mowed.
Contact your dealer for further information.
2.5 One Automower in several gardens
One Automower can easily be used for more than one garden, where each garden has its own charging station and boundary wire. The mower can then have the same PIN code for all gardens.
Contact your dealer for further information.

3. Installation
3. Installation
This chapter describes how you install Automower from Husqvarna™. Before starting the installation read the previous chapter 2. Presentation.
Read the whole of this chapter too before starting the installation. How the installation is made also affects how well Automower 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, boundary wire and guide wire, if used. Draw on the sketch how the boundary wire and the guide wire, if used, 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 Checking the installation.
3.7 Linking the Automower to the charging station.
3.8 Installation of the guide wire.
To carry out a complete start-up of an Automower the charging station must be in position and connected, the boundary wire connected, and the mower connected to the charging station. If you would like to start the mower without having completed the full boundary installation, you can connect a temporary short loop around the mower.

3.1 Preparations
1. If the lawn in the proposed working area is taller than 4", 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 Automower, what’s what? on page 11.
• Operator’s Manual (26)

3.2 Installation of the charging
station
Ideal position of the charging station
For examples of good positioning of the charging station, see 7. Garden example - proposed installation and settings on page 65.
If you are going to install a guide wire, read 3.8 Installation of the guide wire, see page 34, before choosing the position of the charging station.
Automower from 19
3. Installation
The charging station must be positioned with a great deal of free area in front of it (at least 10 ft). It should also be positioned centrally in the working area so that Automower can easily find the charging station and quickly reach all parts of 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.
The charging station must be positioned on relatively level ground. The height difference must not differ more than 2" between the front and rear of the charging station.
The charging station must not be positioned so that its plate bends.
3012-510
3012-712
Consider the distance to a wall socket when choosing the position. The charging station should be connected to a 120V wall socket via the low voltage cable and transformer.
The supplied low voltage cable is 66 ft long.
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 wall or by the closest wall socket.
IMPORTANT INFORMATION
The low voltage cable must not be extended.
IMPORTANT INFORMATION
The transformer is for indoor use only.
The transformer must be placed where it is well ventilated and is not exposed to direct sunlight.
It is recommended to use an earth fault-breaker when connecting the transformer to the wall socket.

3.3 Charging the battery
The Automower is supplied with an uncharged battery. As soon as the charging station is connected, it is possible to charge the mower.
1. Set the main switch to the OFF position.
2. Place the Automower in the charging station to charge the battery while you are laying the boundary wire.
From an uncharged state the battery takes about 1 1/2 to 2 1/2 hours until it is fully charged.
IMPORTANT INFORMATION
Automower cannot be used before the installation is complete.
3.4 Installation of the boundary wire
3. Installation
3012-385
The boundary wire can be installed in one of the following ways:
Securing the wire to the ground with staples.
It is preferable to staple down the boundary cable, if you want to make adjustments to the boundary wire during the first few weeks of operation.
•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. Only an original boundary wire must be used. This is tinned and has a high quality insulation to withstand the dampness in the ground.
Is a maximum of 1640 ft long.
Maintains a maximum distance of 10 ft from Automower in the entire working area.
Automower from 23
3. Installation
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.
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 14" from the obstacle. This will prevent the Automower 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 (1" - 2"), the boundary wire should be laid 12" inside the working area. This prevents the wheels from driving into the ditch or up onto the verge.
3012-713
3012-714
24 Automower from
3012-715
If the working area borders against a flat path or the like that lies level with the lawn, it is possible to allow the Automower to run a little over the path. The boundary wire should then be laid 4" 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 the Automower 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 Automower must never run over a gravel
path or similar material, which can damage the blades.
3. Installation
3012-716
If the working area borders against, for example, pools of water the boundary wire should be supplemented with a fence or the like. The height must then be at least 6". This will prevent the Automower, under any circumstances, coming outside of the working area.
When Automower searches for the charging station or follows the loop according to the function Follow loop (3-2) (see page 53), it runs along the side of the boundary wire at a specific distance. The Corridor width (3-2-3) function determines the distance from the boundary wire that the mower shall run. It is recommended to state as high a Corridor width value as possible. A high Corridor width value reduces the risk of tracks forming. For more information about Corridor width (3-2-3), see page 56.
In exceptional cases Automower can be set to straddle the boundary wire, that is to say, half the mower inside the loop and the other half outside. The boundary wire must then be kept at a distance of about 16" from all the boundaries of the working area and from the edges of a passage.
3012-534
3012-717
Automower from 25
3. Installation
Boundaries within the working area
Use the boundary wire to demarcate areas inside the working area by creating islands around obstacles that can not withstand a collision, for example, flower beds and fountains. Run the cable out to the area, route it around the area to be demarcated and then back along the same route. If staples are used, the wire should be laid under the same staple on the return route. When the boundary wire to and from the island are close together, the mower can drive over the wire.
Obstacles that can withstand a collision, for example, trees or bushes higher than 6", do not need to be demarcated by the boundary wire. The Automower will turn when it collides with this type of obstacle.
However, for the most gentle and silent operation, it is preferable to demarcate 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. Automower can otherwise slide up onto this kind of obstacle causing the blades to be damaged.

When the working area is made up of two areas that are not joined by a sufficiently wide passage, it is recommended to create a secondary area. Run the boundary wire then around the secondary area so that it forms an island outside of the main area.
Automower must be moved manually between the main and secondary areas. Use the MAN operating mode when Automower shall mow a secondary area.
