1.1.2 Product description

Note: Husqvarna regularly updates the appearance and function of the products. Refer to Support on page 3.

The product is a robotic lawn mower. The product has a battery power source and cuts the grass automatically. It continuously alternates between mowing and charging. The movement pattern is random, which means that the lawn is mowed evenly and with less wear. The boundary wire and the guide wire controls the movement of the product within the work area. Sensors in the product senses when it is approaching the boundary wire. The front of the product always passes the boundary wire by a specific distance before the product turns around. When the product hits an obstacle or approaches the boundary wire the product selects a new direction.

The operator selects the operation settings with the keys on the keypad. The display shows the selected and possible operation settings, and the operation mode of the product.

1.1.2.1 Mowing technique

The product is emission free, easy to use and saves energy. The frequent cutting technique improves the grass quality and decreases the use of fertilizers. Collection of grass is not necessary.

1.1.2.2 Find the charging station

The product operates until the battery state of charge is low. Then it follows the guide wire to the charging station. The guide wire is laid from the charging station towards, for instance, a remote part of the work area or through a narrow passage. The guide wire is connected with the boundary wire and makes it much easier and faster for the product to find the charging station.

1.1.2.3 Automower® Connect

Automower® Connect is a mobile application that makes it possible to select the operation settings remotely. Refer to Automower® Connect app on page 25.

3.1 Introduction - Installation

WARNING: Read and understand the safety chapter before you install the product.

CAUTION: Use original spare parts and installation material.

Note: Refer to www.husqvarna.com for more information about installation.

3.2 Main components for installation

The installation involves the following components:

•A robotic lawn mower that mows the lawn automatically.

•A charging station, which has 3 functions:

•To send control signals along the boundary wire.

•To send control signals along the guide wire so that the product can follow the guide to specific remote areas in the garden and can find its way back to the charging station.

•To charge the product.

•A power supply, which is connected to the charging station and a 100-240V wall socket.

•Loop wire, which is laid around the work area and around objects and plants that the product must not run into. The loop wire is used both as boundary wire and guide wire.

3.3 General preparations

CAUTION: Holes with water in the lawn can cause damage to the product.

Note: Read through the Installation chapter before beginning the installation. How the installation is done affects how the product

performs. It is therefore important to plan the installation carefully.

•Make a blueprint of the work area and include all obstacles. This makes it easier to see the ideal positions for the charging station, the boundary wire and the guide wire.

•Make a mark on the blueprint where to put the charging station, the boundary wire and the guide wire.

•Make a mark on the blueprint where the guide wire connects to the boundary wire. Refer to To install the guide wire on page 23.

•Fill in holes in the lawn.

•Cut the grass before you install the product. Make sure that the grass is maximum 10 cm / 3.9 in.

Note: The first weeks after installation the perceived sound level when cutting the grass may be higher than expected. When the product has cut the grass for some time, the perceived sound level is much lower.

3.4 Before the installation of the wires

You can select to attach the wires with stakes or bury them. You can use the 2 procedures for the same work area.

•Bury the boundary wire or the guide wire if you are going to use a dethatcher on the work area. If not, attach the boundary wire or guide wire with stakes.

3.4.1 To examine where to put the charging station

•Keep a minimum 3 m / 10 ft. of free space in front of the charging station. Refer to To examine where to put the guide wire on page 20.

•Keep a minimum of 1.5 m / 5 ft. of free space to the right and left of the center of the charging station.

•Put the charging station near a power outlet.

•Put the charging station on a level surface.

1201 - 004 - 25.03.2020

•Put the charging station in the lower section of the work area.

•Put the charging station in an area with protection from the sun.

•If the charging station is installed on an island, make sure to connect the guide wire to the island. Refer to To make an island on page 19.

3.4.2 To examine where to put the power supply

WARNING: Do not cut or extend the low-voltage cable. There is a risk of electrical shock.

CAUTION: Make sure that the blades on the product do not cut the lowvoltage cable.

WARNING: The power supply cable and extension cable must be outside the work area to avoid damage to the cables.

CAUTION: Do not put the low-voltage cable in a coil or below the charging station plate. The coil causes interference with the signal from the charging station.

•Put the power supply in an area with a roof and protection from the sun and rain.

•Put the power supply in an area with good airflow.

•Use a residual-current device (RCD) when you connect the power supply to the power outlet.

Low-voltage cables of different lengths are available as accessories.

3.4.3 To examine where to put the boundary wire

CAUTION: If the work area is adjacent to water bodies, slopes, precipices or a public road, the boundary wire must have a protective wall. The wall must be minimum 15 cm / 6 in. in height.

CAUTION: Do not let the product operate on gravel.

CAUTION: Do not make sharp bends when you install the boundary wire.

CAUTION: For careful operation without noise, isolate all obstacles such as trees, roots and stones.

The boundary wire should be put as a loop around the work area. Sensors in the product senses when the product approaches the boundary wire, and the product selects another direction.

To make the connection easier between the guide wire and the boundary wire, it is

1201 - 004 - 25.03.2020

Installation - 17

recommended to make an eyelet where the guide wire will be connected. Make the eyelet with approximately 20 cm / 8 in. of the boundary wire.

•

Note: Make a blueprint of the work area before you install the boundary wire and guide wire.

Put the boundary wire 30 cm / 12 in. (C) from an obstacle that is 1-5 cm / 0.4-2 in. high.

•Put the boundary wire around all of the work area (A). Adapt the distance between the boundary wire and obstacles.

•Put the boundary wire 35 cm / 14 in. (B) from an obstacle that is more than 5 cm / 2 in. high.

•Put the boundary wire 10 cm / 4 in. (D) from an obstacle that is less than 1 cm / 0.4 in. high.

•If you have a paving stone path that is in level with the lawn, put the boundary wire below the paving stone.

Note: If the paving stone is minimum 30 cm / 12 in. wide, use the factory setting for the Drive Past Wire function to cut all the grass adjacent to the paving stone. Refer to To set the Drive Past Wire function on page 33.

•If you make an island, put the boundary wire that runs to and from the island near together (E). Put the wires in the same stake. Refer to To make an island on page 19.

18 - Installation

1201 - 004 - 25.03.2020

•Make an eyelet (F) where the guide wire is to be connected to the boundary wire.

3.4.3.1 To put the boundary wire in a slope

The product can operate in 45% slopes. Slopes that are too steep must be isolated with the boundary wire. The gradient (%) is calculated as height per m. Example: 10 cm / 100 cm = 10%.

•For slopes steeper than 45% inside the work area, isolate the slope with boundary wire.

•For slopes steeper than 15% along the outer edge of the lawn, put the boundary wire 20 cm / 8 in. (A) from the edge.

•For slopes adjacent to a public road, put a fence or a protective wall along the outer edge of the slope.

•Make sure that there is as much free area as possible to the left of the guide wire. The product moves on the left side of the guide wire, when you face the charging station.

3.4.3.2 Passages

A passage is a section that has boundary wire on each side and that connects 2 work areas. The passage must be a minimum of 60 cm / 24 in. between the boundary wire.

Note: If a passage is less than 2 m / 6.5 ft. wide, install a guide wire through the passage.

The product always runs to the left of the guide wire as seen facing the charging station. Make

sure that the guide wire has as much free area as possible to the left of the guide wire.

3.4.3.3 To make an island

CAUTION: Do not put a section of boundary wire across the other. The sections of boundary wire must be parallel.

CAUTION: Do not put the guide wire across the boundary wire, for example a boundary wire that goes to an island.

Some obstacles can withstand a collision, for example, trees or bushes taller than 15 cm / 6 in. The product will collide and then turn around with this type of obstacle. However, obstacles that slope slightly, for example stones or large trees

1201 - 004 - 25.03.2020

Installation - 19

with raised roots, must be isolated or removed. The product can run onto this kind of obstacle causing the blades to be damaged. Use the boundary wire to isolate areas inside the work area by creating islands. When the boundary wires to and from the island are put close together, the product can run over the wire.

Note: To achieve careful and silent operation, it is recommended to isolate all fixed objects in the work area.

•Put the boundary wire to and around the obstacle to make an island.

•Put the 2 sections of boundary wire that run to and from the obstacle close together without crossing.

•Put the 2 sections of boundary wire in the same stake.

3.4.3.4 To make a secondary area

Make a secondary area (B) if the work area has 2 areas that are not connected with a passage. The work area with the charging station is the main area (A).

Note: The product must be manually moved between the main area and the secondary area.

•Put the boundary wire around the secondary area (B) to make an island. Refer to To make an island on page 19.

Note: The boundary wire must be put as 1 loop around all of the work area (A + B).

Note: When the product cuts grass in the secondary area, the Secondary area mode must be selected. Refer to Operating mode Start on page 39.

3.4.4 To examine where to put the guide wire

•Put the guide wire in a line at a minimum of 2 m / 6.5 ft. in front of the charging station.

•Make as much free area as possible to the left of the guide wire when facing the charging station. Refer to Corridor width on page 32.

•Put the guide wire minimum 30 cm / 12 in. from the boundary wire.

•Do not make sharp bends when you install the guide wire.

•If the work area has a slope, put the guide wire diagonally across the slope.

20 - Installation

1201 - 004 - 25.03.2020

3.4.5 Work area examples

•If the charging station is put in a small area (A), make sure that the distance to the boundary wire is at a minimum 3 m / 10 ft. in front of the charging station.

•If the work area has a passage (B), make sure that the distance to the boundary wire is at a minimum 2 m / 6.5 ft. If the passage is smaller than 2 m / 6.5 ft., install a guide wire through the passage. Minimum passage between the boundary wire is 60 cm / 24 in.

•If the work area has areas which are connected by a narrow passage (B), you can set the product to first follow and then leave the guide wire after a certain distance
