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 power outlet. · 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

· Make a mark on the blueprint where the guide wire connects to the boundary wire. Refer to To install the guide wire on page 21.
· Fill in holes in the lawn. · Cut the grass before you install the product. Make
sure that the grass is maximum 10 cm / 4 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.
CAUTION: If you use a dethatcher in
the work area, bury the boundary wire and the guide wire to prevent them from damage.
3.4.1 To examine where to put the charging station
· Keep a minimum 2 m / 7 ft. of free space in front of the charging station. Refer to To examine where to put the guide wire on page 18.
· Keep a minimum of 150 cm / 60 in. of free space to the right and left of the center of the charging station.

CAUTION: Do not let the product
operate on gravel.

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

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 low-voltage cable.

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. All parts of the work area must be maximum 35 m / 115 ft. from the boundary wire.
To make the connection easier between the guide wire and the boundary wire, it is 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.

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.

5 Maintenance

5.1 Introduction - maintenance WARNING: The product must be
switched off before any maintenance is done. The product is disabled when the LED status indicator is not lit.
WARNING: Wear protective gloves.

5.2.1 Chassis and blade disc
Inspect the blade disc and blades once a week.
1. Set the Main switch to position 0.
2. Lift the product onto its side.
3. Clean the blade disc and chassis using for example a dish brush. At the same time, check that the blade disc rotates freely in relation to the foot guard. Also, check that the blades are intact and can pivot freely.

For better operation and longer service life, make sure to clean the product regularly and replace worn parts. All maintenance and servicing must be done according to Husqvarna's instructions. Refer to Warranty on page 52.
When the product is first used, the blade disc and blades should be inspected once a week. If the amount of wear during this period has been low, the inspection interval can be increased.
It is important that the blade disc rotates easily. The edges of the blades should not be damaged. The lifetime of the blades varies immensely and depends for instance on:
· Operating time and size of the work area. · Type of grass and seasonal growth. · Soil, sand and use of fertilizers. · The presence of objects such as cones, windfalls,
toys, tools, stones, roots and the like.
The normal life is 2 to 5 weeks when used under favorable conditions. Refer to Replace the blades on page 35 on how to replace the blades.
Note: Working with blunt blades gives a poorer
mowing result. The grass is not cut cleanly and more energy is needed resulting in the product not mowing such a large area.

5.2.2 Chassis
Clean the underside of the chassis. Brush or wipe with a damp cloth.
5.2.3 Wheels
Clean around the wheels. Grass on the wheels can impact on how the product performs in slopes.
5.2.4 The body of the product
Use a moist, soft sponge or cloth to clean the body of the product. If the body of the product is dirty, use a mild soap solution to clean it.
5.2.5 Charging station
WARNING: Use the plug to disconnect
the charging station before any maintenance, or cleaning of charging station or power supply.

5.2 Clean the product
It is important to keep the product clean. A product with large amounts of grass stuck to it will not cope as well with slopes. It is recommended to clean using a brush.
Husqvarna recommends to use a special cleaning and maintenance kit, available as an accessory. Contact your Husqvarna representative for more information.
CAUTION: Never use a high-pressure
washer to clean the product. Never use solvents for cleaning.

Clean the charging station regularly from grass, leaves, twigs and other objects that may impede docking.

34 - Maintenance

1457 - 005 - 16.10.2020

5.3 Replace the blades
WARNING: Use blades and screws of
the right type. Husqvarna can only guarantee safety when using original blades. Only replacing the blades and reusing the screw can result in a screw wearing during mowing. The blades can then be propelled from under the body and cause serious injury.
Replace worn or damaged parts for safety reasons. Even if the blades are intact, they should be replaced on a regular basis for the best mowing result and low energy usage. All 3 blades and screws must be replaced at the same time to obtain a balanced cutting system. Use Husqvarna original blades embossed with the crowned H-mark logotype, refer to Technical data on page 49.

7. Attach 3 new blades and screws. 8. Make sure that the blades can pivot freely.
5.4 Battery
WARNING: Only charge the product
using a charging station which is intended for it. Incorrect use may result in electric shock, overheating or leakage of corrosive liquid from the battery. In the event of leakage of electrolyte flush with water and seek medical help if it comes in contact with the eyes etc.
WARNING: Use only original batteries
recommended by the manufacturer. Product safety cannot be guaranteed with other batteries. Do not use non-rechargeable batteries.

5.3.1 To replace the blades
1. Push the STOP button 2. Set the Main switch to position 0.

CAUTION: The battery must charge a
complete cycle before winter storage. If the battery is not fully charged it can be damaged and in certain cases be rendered useless.
If the operating time for the product is shorter than normal between charges, this indicates that the battery is getting old and eventually needs replacing.
Note: Battery life is dependent on the length of the
season and how many hours a day the product is operating. A long season or many hours of use a day means that the battery must be replaced more regularly. The battery is fine as long as the product maintains a well-cut lawn.

3. Turn the product upside down. Put the product on a soft and clean surface to avoid scratching the product.
4. Rotate the skid plate so that its holes align with the screws for the blade.
5. Remove the 3 screws with a screwdriver.
6. Remove the 3 blades.

5.5 Winter service
Take your product to your Husqvarna central service for service prior to winter storage. Regular winter service will maintain the product in good condition and create the best conditions for a new season without any disruptions.
Service usually includes the following:
· Thorough cleaning of the body, the chassis, the blade disc and all other moving parts.
· Testing of the product's function and components. · Checking and, if required, replacing wear items
such as blades and bearings. · Testing the product's battery capacity as well as a
recommendation to replace battery if necessary. · If new firmware is available, the product is
updated.

6.7 Finding breaks in the loop wire
Breaks in the loop wire are usually the result of unintentional physical damage to the wire such as when gardening with a shovel. In countries with ground frost, also sharp stones that move in the ground can damage the wire. Breaks can also occur due to the wire being stretched excessively during installation.
Mowing the grass too low right after the installation can damage wire insulation. Damage to the insulation may not cause disruptions until several weeks or months later.
CAUTION: Always select the maximum
cutting height the first weeks after installation and then lower the height one step at a time every second week until the desired cutting height has been reached.
A defective splicing of the loop wire can also lead to disruptions several weeks after the splice was done. A

faulty splice can, for example, be the result of the coupler not being pressed together hard enough with a pair of pliers, or that a coupler of lower quality than the original coupler has been used.
Note: Please first check all known splices before
further troubleshooting is done.
A wire break can be located by gradually halving the distance of the loop where the break may have occurred until there is only a very short section of the wire left.
The following method does not work if ECO mode is activated. Make sure first that ECO mode is turned off. Refer to ECO mode on page 25.
1. Check that the indicator lamp in the charging station flashes blue, which indicates a break in the boundary loop. Refer to LED indicator lamp on the charging station on page 43.

1457 - 005 - 16.10.2020

Troubleshooting - 45

2. Check that the boundary wire connections to the charging station are properly connected and not damaged. Check that the indicator lamp in the charging station is still flashing blue.
AR POWER AL
G1
3. Switch the connections between the guide wire and the boundary wire in the charging station. Start by switching connection AL and G1. Some models have additional guide wires . The same procedure can be followed for them.
If the indicator lamp is lit with a solid green light, then the break is somewhere on the boundary wire between AL and the point where the guide wire is connected to the boundary wire (thick black line in the illustration).

AL G1
Guide
To rectify the fault you will need boundary wire, connector(s) and coupler(s): a) If the suspected boundary wire is short then it is easiest to exchange all of the boundary wire between AL and the point where the guide wire is connected to the boundary wire (thick black line). b) If the suspected boundary wire is long (thick black line) then do as follows: Put AL and G1 back to their original positions. Then disconnect AR. Connect a new loop wire to AR. Connect the other end of this new loop wire at the middle of the suspected wire section.

46 - Troubleshooting

1457 - 005 - 16.10.2020

Continue until only a very short section of the wire

remains which is the difference between a solid

green light and a flashing blue light. Then follow

instruction in step 5 below.

4. If indicator lamp still flashes blue in step 3

above: Put AL and G1 back in their original positions. Then switch AR and G1. If indicator lamp

now is lit with a solid green light then disconnect

AL and connect a new boundary wire to AL.

Connect the other end of this new wire at the

middle of the suspected wire section. Follow the

same approach as in 3a) and 3b) above.

5. When the break is found, the damaged section

must be replaced with a new wire. Always use

original couplers.

If the indicator lamp now is green, then the break is somewhere in the wire between the disconnected end to the point where the new wire is connected (thick black line below). In that case, move the connection for the new wire closer to the disconnected end (roughly at the middle of the suspected wire section) and check again if the indicator lamp is green.
