PRESENTATION 2 Presentation This chapter contains information that is important to be aware of when planning the installation. Installing a Husqvarna robotic lawnmower involves four main components: • A robotic lawnmower that mows the lawn by essentially operating in a random pattern. The robotic lawnmower is powered by a maintenance-free battery. 3012-1040 • A charging station, to where the robotic lawnmower automatically returns when the charge level in the battery becomes too low.

PRESENTATION 2.2 Package content Your Automower® package will include the following parts.
PRESENTATION Mowing technique The cutting system in the Husqvarna robotic lawnmower is based on an efficient and energy saving principle. Unlike many standard lawnmowers, the robotic lawnmower cuts the grass instead of knocking it off. We recommend you allow the robotic lawnmower to mainly mow in dry weather to obtain the best possible result.
PRESENTATION The STOP button on the top of the robotic lawnmower is mainly used to stop the robotic lawnmower when it’s running. When the STOP button is pressed a hatch opens, behind which there is a control panel. The STOP button remains pressed in until the hatch is closed again. This together with the START button acts as a start inhibitor. 3012-1044 The control panel on the top of the robotic lawnmower is where you manage all the robotic lawnmower settings.
PRESENTATION Search method 2: Follow guide wire The robotic lawnmower operates irregularly until it reaches the guide wire. Then the robotic lawnmower follows the guide wire to the charging station. The guide wire is a wire 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 loop. See 3.6 Installation of the guide wire on page 28.
INSTALLATION 3 Installation This chapter describes how to install the robotic lawnmower. Before starting the installation read the previous chapter 2. Presentation. Read also through this entire chapter before beginning the installation. How the installation is done also affects how well the robotic lawnmower works. It is therefore important to plan the installation carefully. Planning is simplified if you make a sketch of the working area, including all obstacles.
INSTALLATION 4. Check that all parts for the installation are included. The numbers in brackets refer to the component illustration. See 2.1 What is what? on page 10.
INSTALLATION The charging station must be positioned with a great deal of free space in front of it (at least 3 metres). It should also be centrally placed in the working area to make it easier for the robotic lawnmower to reach all areas in the working area. 3012-559 Do not put the charging station in confined spaces in the working area. This can make it difficult for the robotic mower to find the charging station. 3012-555 The charging station must be positioned on relatively level ground.
INSTALLATION Connecting the transformer Take the following into consideration when planning where to place the transformer: • Close to the charging station • Protection from rain • Protection from direct sunlight If the transformer is connected to an electrical socket outdoors, this must be approved for outdoor use. 3012-1214 The low voltage cable for the transformer is 10 metres long, and may not be shortened or extended. A longer low voltage cable is available as optional accessory.
INSTALLATION Do not, under any circumstances, mount the transformer at a height where there is a risk it can be submerged in water (at least 30 cm from the ground). It is not permitted to place the transformer on the ground. IMPORTANT INFORMATION Use the transformer’s plug to disconnect the charging station, for instance before cleaning or repairing the loop wire. Installing and connecting the charging station 1. Position the charging station in a suitable spot. 2.
INSTALLATION 3.3 Charging the battery As soon as the charging station is connected, it is possible to charge the robotic lawnmower. Set the main switch to position 1. Place the robotic lawnmower in the charging station to charge the battery while the boundary and guide wires are being laid. 3012-1046 IMPORTANT INFORMATION The robotic lawnmower cannot be used before the installation is complete.
INSTALLATION 3.4 Installation of the boundary wire The boundary wire can be installed in one of the following ways: • Secure the wire to the ground with pegs. It is preferable to staple down the boundary wire if you want to make adjustments to the boundary loop during the first few weeks of operation. After a few weeks the grass will have grown over the wire making it no longer visible. Use a hammer/plastic mallet and the pegs supplied when carrying out the installation. • Bury the wire.
INSTALLATION Working area boundaries If a high obstacle, for example a wall or fence, borders the working area, the boundary wire should be laid 35 cm from the obstacle. This will prevent the robotic lawnmower from colliding with the obstacle and reduce body wear. About 20 cm of the lawn around the fixed obstacle will not be mown.
INSTALLATION Boundaries within the working area Use the boundary wire to isolate areas inside the working area by creating islands around obstacles which cannot withstand a collision, for example flowerbeds, bushes and fountains. Lay the wire up to and around the area to be isolated, and then return it back along the same route. If pegs are used, the wire should be laid under the same pegs on the return route.
INSTALLATION Passages when mowing Long and narrow passages and areas narrower than 1.5 to 2 metres should be avoided. When the robotic lawnmower mows, there is a risk that it travels around in the passage or area for a long period of time. The lawn will then look flattened. 3012-1088 Slopes The robotic lawnmower can also operate on sloping working areas. The maximum gradient is defined as percentage units (%).
INSTALLATION Laying the boundary wire If you intend to peg down the boundary wire: • Cut the grass very low with a standard lawnmower or a trimmer where the wire is to be laid. It will then be easier to lay the wire close to the ground and the risk of the robotic lawnmower cutting the wire or damaging the insulation of the wire is reduced. • Make sure to lay the boundary wire close to the ground and secure the pegs close together approximately 75 cm apart.
INSTALLATION Laying the boundary wire in towards the charging station On its way toward the charging station, the boundary wire can be laid completely outside the charging station (see option 1 in the figure). If there is a need to partly locate the charging station outside the working area, it is also possible to lay the wire under the charging station plate (see option 2 in the figure).
INSTALLATION 3.5 Connecting the boundary wire Connect the boundary wire to the charging station: IMPORTANT INFORMATION The boundary wire must not be crossed when connecting it to the charging station. The right hand wire end must be connected to the right hand pin on the charging station and the left hand wire end to the left pin. 1. Place the wire ends in the connector: • Open the connector. • Place the wire in the connector grip. 3012-284 2. Press the connectors together using a pair of pliers.
INSTALLATION 3.6 Installation of the guide wire The guide wire is a wire 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 loop. The same cable roll is used for both the boundary loop and guide wire. The guide wire is used by the robotic lawnmower to find its way back to the charging station but also to guide the robotic lawnmower to hard-to reach areas of the garden.
INSTALLATION Laying and connecting the guide wire 1. Before laying and connecting the guide wire, it is important to give consideration to the length of the guide loop, especially in large or complex installations. If the guide loop is longer than 400 metres the robotic lawnmower can have difficulty following the guide wire. The guide wire together with the section of the boundary loop that makes up the return wire to the charging station is called the guide loop.
INSTALLATION If the guide wire has to be installed on a steep slope, it is an advantage to lay the wire at an angle to the slope. This makes it easier for the robotic lawnmower to follow the guide wire on the slope. 3018-061 Avoid laying the wire at sharp angles. This can make it difficult for the robotic lawnmower to follow the guide wire. 135º 135º 90º 3012-953 6. Run the guide wire to the point on the boundary loop where the guide wire is to be connected. Lift up the boundary wire.
INSTALLATION 3.7 Checking the installation Check the loop signal by inspecting the indicator lamp on the charging station. • Solid green light = good signals. • Flashing green light = the loop system is turned off and the robotic lawnmower is in ECO mode. See 6.9 Settings on page 59. • Flashing blue light = interruption in the boundary loop, no signal. • Flashing red light = interruption in the charging station’s antenna plate. The fault should be rectified by an authorised dealer.
INSTALLATION 3.8 First start-up and calibration Before the robotic lawnmower is operated, a start-up sequence in the robotic lawnmower’s menu must be carried out as well as an automatic calibration of the guide signal. 1. Open the control panel hatch by pressing the STOP button. 2. Set the main switch to position 1. A start-up sequence begins when the robotic lawnmower is started for the first time. The following is requested: • Language • Country • Date • Time • Four digit PIN code.
USE 4 Use 4.1 Charging a flat battery When the Husqvarna robotic lawnmower is new or has been stored for a long period, the battery will be flat and needs to be charged before starting. 1. Set the main switch to position 1. 2. Park the robotic lawnmower in the charging station. Open the cover and slide the robotic lawnmower in as far as possible to ensure proper contact between the robotic lawnmower and the charging station. 3012-1046 3. The display shows a message that charging is in progress.
USE 4.2 Using the timer The lawn should not be cut too often to obtain the best mowing result. Use the timer function (see 6.3 Timer on page 42) to avoid a downtrodden lawn and to get the maximum service life from the robotic lawnmower. When setting the timer, calculate that the robotic lawnmower mows about 135 m2 per hour and day (90 m2 for Automower® 320). For example; If the working area is 1,200 m2 the robotic lawnmower must operate for about 9 hours per day (13 hours for Automower® 320).
USE 4.4 Stopping 1. Press the STOP button. The robotic lawnmower stops, the blade motor stops and the control panel hatch opens. 4.5 Switching off 3012-1044 1. Press the STOP button. 2. Set the main switch to position 0. Always switch the robotic lawnmower off using the main switch if it requires maintenance or if the robotic lawnmower must be moved outside the working area. Adjusting the cutting height 3012-1060 The cutting height can be varied from MIN (2 cm) to MAX (6 cm) in nine stages.
CONTROL PANEL 5 Control panel All forms of commands and settings for the robotic lawnmower are made via the control panel. All functions are accessed via a number of menus. 3012-1044 The control panel consists of a display and a keypad. All information is shown on the display and all input is done using the buttons. When the stop button has been pressed and the hatch is opened, the start page is displayed showing the following information: • Operating information, e.g. MOWING, PARKED or TIMER.
CONTROL PANEL The keypad consists of six groups of buttons: • The START button is used to activate the robotic lawnmower. This is normally the last button to be pressed before closing the display hatch. • The Back and OK buttons are used to navigate in the menu. The OK button is also used to confirm settings in the menu. • The arrow keys are used to navigate in the menu but also to make selections in certain setting options. • The MENU button is used to go to the main menu.
CONTROL PANEL Override timer Any timer settings made can be temporarily overridden by selecting Override timer. It is possible to override the timer for 1, 3 or 5 days. Spot Cutting Spot cutting means the robotic lawnmower will work in a spiral pattern in order to cut the grass in the area where it was started. When this is done, the robotic lawnmower will automatically switch to Main Area or Secondary Area.
CONTROL PANEL 5.3 Main switch Set the main switch in the 1 position to start the robotic lawnmower. Set the main switch in the 0 position when the robotic lawnmower is not in use or work is being carried out on the blade disc. When the main switch is set in the 0 position the motors on the robotic lawnmower cannot start. 3012-1060 5.4 The charging station’s PARK button This section does not apply to Automower® 320.
MENU FUNCTIONS 6 Menu functions 6.1 Main menu The main menu consists of the following options: • Timer • Cutting height • Security • Messages • Weather timer • Installation • Settings • Accessories 3012-1264 There are a number of submenus under each option. You can access all the functions to set the robotic lawnmower settings via these. Browse between menus Browse through the main menu and submenus with the help of the arrow keys.
MENU FUNCTIONS 6.2 Menu structure The following table summarises the menu selections found in the main menu. The following chapter provides more detailed information about how each function is used and which setting options are available. Use the arrow keys to browse the menu. Confirm selections with OK. Timer The lawn should not be cut too often to obtain the best mowing result.
MENU FUNCTIONS 6.3 Timer The lawn should not be cut too often to obtain the best mowing result. Consequently, it is important to limit the operating time using the timer function if the working area is less than the mower’s working capacity. When the robotic lawnmower is allowed to mow too often, the lawn may appear flattened. Besides, the robotic lawnmower is subjected to unnecessary wear.
MENU FUNCTIONS Overview This function graphically displays what hours and days the robotic lawnmower is operating. The time the robotic lawnmower will mow is marked with a black line. During the other times, the robotic lawnmower is parked in the charging station. 3012-1235 Reset This function resets the timer to the factory setting, where the robotic lawnmower is allowed to operate 24 hours a day every day. Current day This resets the day that is selected in the tab system.
MENU FUNCTIONS 6.4 Cutting height The cutting height can be varied from MIN (2 cm) to MAX (6 cm). During the first week after a new installation, the cutting height must be set to MAX to avoid damaging the loop wire. After this, the cutting height can be reduced one step every week until the desired cutting height has been reached. Cutting height Cutting height If the grass is long, allow the robotic lawnmower to start mowing at the MAX cutting height.
MENU FUNCTIONS 6.5 Security Through this selection, settings relating to security and the connection between the robotic lawnmower and the charging station can be made. There are three security levels to choose from but it is also possible to define your own combination of security functions. The factory setting is security level Medium. Security Security level Change PIN Code Advanced Reset security New loop signal settings Use the down and up arrow keys to select a security level.
MENU FUNCTIONS Custom This menu allows you to customise and combine the available security functions to suit your needs. Time lock Activate or deactivate the PIN request after a certain number of days. The number of days can be set in Security - Advanced. NOTE! Time lock is the most important theft-prevention function and it is recommended to have it activated at all times. PIN if stopped Activate or deactivate PIN request when the STOP button has been pressed.
MENU FUNCTIONS 3. Press OK and await confirmation that the loop signal has been generated. This normally takes about 10 seconds. Advanced Duration of Time lock When Time lock is activated there is also the possibility to select how many days the robotic lawnmower has to request a PIN code. A figure between 1 and 90 can be selected. The factory setting is 30 days. Duration of Alarm When Alarm is activated there is also the possibility to select how long the alarm signal should last.
MENU FUNCTIONS Info messages Messages shown in the display not caused by an actual fault are instead saved under the Info messages heading. Examples for such messages are Weak GPS signal and Slope too steep. See 9.1 Fault messages on page 75 for more information on possible reasons for each message. By date This list contains the latest 50 fault messages sorted by date with the last incident to occur first on the list.
MENU FUNCTIONS Cutting time If the mowing results are not optimal when using the Weather timer, Cutting time settings may need adjusting. To adjust the Cutting time: place the cursor by Cutting time and use the right and left arrow keys to increase or decrease the cutting time in three preset intervals. The longer cutting time that is chosen, the longer the robotic lawnmower will be allowed to work. 6.
MENU FUNCTIONS In general a long delay time decreases the risk of tracks forming (the robotic lawnmower will find the charging station more often through irregular searches) but gives longer search times. A short delay time gives the opposite effect, i.e. short search times with increased risk of tracks forming along the guide wires and/or boundary wires. Guide Make sure the Follow guide home checkbox is activated. Otherwise use the down arrow key to select the checkbox and then press OK.
MENU FUNCTIONS Charging station range There may be reasons to reduce the range of the charging station in rare cases. It may be necessary if for instance the charging station is placed close to a bush or wall which prevents the robotic lawnmower from docking with the charging station despite making contact with the charging station’s signals. In these cases, it is normally better to move the charging station, but if this is not possible, the range of the charging station can be reduced.
MENU FUNCTIONS Normal causes as to why the robotic lawnmower cannot follow the wire are that obstacles close to the wire have not been isolated or that the guide wire has not been laid at an angle on a steep slope. Check that the charging station, the boundary wire and the guide wire are installed in accordance with the instructions in Chapters 3.2, 3.4 and 3.6. If manual settings are done, the wrong corridor width may also have been selected. 4.
MENU FUNCTIONS IMPORTANT INFORMATION When the GPS assisted navigation is activated, this will be used so long there is a GPS service - even if manual settings are carried out. Only when a GPS service is not available will the manual settings be used. 3012-1078 Area 1-5 > How? Specify to the right, left or Guide 1 (also Guide 2 for Automower® 330X) depending on which direction the area lies from the charging station. The direction (right or left) is counted as that seen facing the charging station.
MENU FUNCTIONS GPS This section does not apply to Automower® 320. GPS assisted navigation uses an inbuilt GPS to check which areas are mowed and thereby which areas need to be mowed next. After a number of days operating, the robotic lawnmower creates a map of the working area and where the guide wires are laid. In this way Automower® 330X can automatically set distance and proportion for hard to reach parts of the working area.
MENU FUNCTIONS How to measure the distance to a remote area: 1. Park the robotic lawnmower in the charging station. 2. In the Lawn coverage > How far? menu function, enter a distance which beyond any doubt exceeds the real figure. The maximum distance that can be entered is 499 metres. 3. Select Lawn coverage > Overview > Test and press OK. 4. Press START and close the display hatch. 5. Press STOP at the required position and measure the distance. This figure can now be entered in Lawn coverage > How far?.
MENU FUNCTIONS Advanced Under the Advanced heading, there are even more settings relating to the behaviour of the robotic lawnmower. The settings in this menu are only required if additional control of the lawnmower is definitely needed e.g. in very complex gardens. The factory settings are selected in way that should suit most working areas.
MENU FUNCTIONS Corridor width > Guide In the case of the guide wires, specify the widest distance from each guide wire the robotic lawnmower can run. The distance is specified as a figure between 0 and 9. The distance the robotic lawnmower maintains from the guide wire varies depending on the layout of the working area. Use the Test function in Installation > Lawn coverage > Overview to test which value is suitable for the working area in question.
MENU FUNCTIONS Drive past wire The front of the robotic lawnmower always passes the boundary wire by a specific distance before the mower turns around. The default distance is 31 cm, but this can be changed if required. A figure between 20 and 50 can be selected. Note that the distance given is only an approximate value and should be regarded as a guide. In reality, the actual distance the robotic mower passes the boundary wire can vary.
MENU FUNCTIONS 6.9 Settings This selection allows you to carry out changes to the robotic lawnmower’s general settings. Settings Profiles ECO mode Spiral cutting On/Off Time & date Country Cutting height calibration Guide wire calibration Reset all user settings Intensity On/Off Set time Use Language Change name Set date Time format Date format Save Profiles With the function Profiles, different sets of user settings can be saved.
MENU FUNCTIONS Change the name of a profile The names of the profiles can be changed, to make it easier to remember what settings are stored in the respective profile. • Check the profile name to be changed • Press OK • Check Rename and press OK. • Move the cursor withe the arrow keys. Press OK to select a letter. Press BACK to save the new name. • The names of the profiles will be shown in the menu Settings - Profiles. The name of the selected profile is also visible on the start page.
MENU FUNCTIONS ECO This function automatically turns off the loop signal in the boundary loop, the guide wires and the charging station when the robotic lawnmower is not mowing, i.e. when the lawnmower is charging or is not allowed to mow due to timer settings. ECO is suitable to use where there is other wireless equipment not compatible with the robotic lawnmower e.g. certain hearing loops or garage doors.
MENU FUNCTIONS Intensity The level of sensitivity can be adjusted to set how much over the average height the grass has to be for spiral cutting to begin. Low sensitivity means that spiral cutting begins less often. High sensitivity means that spiral cutting begins more often. Time & Date This function allows you to set current time and required time format in the robotic lawnmower. Time Enter the correct time and press OK to exit.
MENU FUNCTIONS Calibration of guide wire The guide wire may need to be calibrated in rare cases. This should only be done if the robotic lawnmower itself requests it or if your dealer recommends it. 1. Park the robotic lawnmower in the charging station. 2. Select Guide calibration and press OK. 3. The robotic lawnmower reverses out of the charging station and runs a calibration process over the guide wire after which it begins to mow.
MENU FUNCTIONS 6.10 Accessories This menu is used for the settings related to accessories fitted on the mower. Headlight In this function, settings regarding headlight are made. Headlight can only be fitted as accessories on the Automower® 330X. Accessories Headlight Schedule In sub menu Schedule, you select when the headlight will be turned on. Select between Always ON, Only Evening, Evening & night or Always OFF.
GARDEN EXAMPLES 7 Garden examples - Installation proposals and settings Adapting the robotic lawnmower’s settings and guide wire positions according to the shape of the garden makes it easier for the robotic lawnmower to frequently reach all parts of the garden and in doing so achieve a perfect mowing result.

MAINTENANCE 8 Maintenance For better operating reliability and longer service life: check and clean the robotic lawnmower regularly and replace worn parts if necessary. See 8.4 Cleaning on page 72 for more details on cleaning. When the robotic lawnmower 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.
MAINTENANCE 8.1 Winter storage The robotic lawnmower The robotic lawnmower must be cleaned carefully before putting it away for the winter. See 8.4 Cleaning on page 72. To guarantee battery functionality and service life, it is very important to fully charge the robotic lawnmower before storing it away for the winter. Place the robotic lawnmower in the charging station with the hatch open until the battery icon in the display shows that the battery is fully charged. Then set the main switch to 0.
MAINTENANCE 8.2 Winter service Leave your robotic lawnmower with a dealer for service prior to winter storage. Regular winter service is a good way to maintain the robotic lawnmower in good condition over a long period of time 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 mower’s function and components.
MAINTENANCE If long blades of grass or other objects find their way in, these may impede the blade disc. Even a slight braking effect leads to a higher consumption of energy and longer mowing times, and at worst will prevent the robotic lawnmower from being able to mow a large lawn. The blade disc must be removed to carry out a more thorough cleaning. If necessary, contact your dealer. 3012-1068 Chassis Clean the underside of the chassis. Brush or wipe with a damp cloth.
MAINTENANCE 8.7 Blades WARNING Always use original blades and screws when replacing. Only replacing the blades and reusing the screw can result in a screw wearing during mowing and shearing. The blades can then be propelled from under the body and cause serious injury. There are three blades on the robotic lawnmower, which are screwed into the blade disc. All three blades and screws must be replaced at the same time to obtain a balanced cutting system.
TROUBLESHOOTING 9 Troubleshooting In this chapter, a number of messages are listed which may be shown in the display if there is a malfunction. There is a proposal as to the cause and steps to take for each message. This chapter also presents some symptoms that can guide you if the robotic lawnmower does not work as expected. More suggestions for steps to take in the event of malfunction or symptoms can be found on www.automower.com. 9.

TROUBLESHOOTING 9.4 Symptoms If your robotic lawnmower does not work as expected, follow the troubleshooting guide below. There is a FAQ (Frequently Asked Questions) on www.automower.com which provides more detailed answers to a number of standard questions. It you still cannot find the reason for the fault, contact the local dealer.
TROUBLESHOOTING The robotic lawnmower runs, but the blade disc does not rotate The robotic lawnmower mows for shorter periods than usual between charges Both the mowing and charging times are shorter than usual The robotic lawnmower follows a guide wire or boundary wire to or from the charging station. This behaviour is normal and no action is required. The robotic lawnmower searches for a guide wire or boundary wire and the battery charge is very low.
TROUBLESHOOTING 9.5 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 be due to the wire being stretched excessively during installation. Mowing the grass too low right after the installation can damage wire insulation.
TROUBLESHOOTING 3. Switch the connections between the guide wire and the boundary wire in the charging station. a) Switch connection AL and G1. 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). 3012-1208 b) Put AL and G1 back in their original positions. Then switch AR and G1.
TROUBLESHOOTING 4. a) Assume that the indicator lamp is lit with a solid green light in test a) above. Reset all connections to their original positions. Then disconnect AR. Connect a new loop wire to AR. Connect the other end of this new loop wire somewhere at the centre of the installation. If the indicator lamp 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 in the illustration below).
TROUBLESHOOTING 5. When the break is found, the damaged section must be replaced with a new wire. The damaged section can be cut out if it is possible to shorten the boundary wire. Always use original couplers.
