    Working capacity 1,800m +/- 20% 1.4 Mower program Automower The behaviour of the Automower from Husqvarna™ is controlled by a microprocessor and software. The software, the mower program, manages all information and the operation of the mower. This Technical Manual for Automower covers edition 2.32 of the mower program.

  • Page 8: Mowing Technique

    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 24V connector should also be removed.

  • Page 9: Square Mode Cutting

    Poor or dull blades can result in the grass bending instead of being mown, the tops become frayed and Automower may find it difficult to mow a large working area. Besides, the lawn can become extremely rumpled and uneven.
  • Page 10 Automower will then start square mode cutting. The limit value for when Automower should start square mode cutting is set to 50% at the factory. The limit value is adjustable from the menu Tools - Special settings - Square mode cutt.

  • Page 11: The Loop System's Control Signals

    The F-signal guides the mower in the direction of the charging station. When there is no F-signal, the Automower will not be able to find the charging station. The mower will eventually stop and display the fault message Low battery voltage.

  • Page 12: Loop Signal Strength

    The signal from the boundary wire is called the A-signal. See the picture below for examples of high and low signal strengths. Out-turned corner = high strength Narrow head = low strength In-turned corner = low strength 3012-612 Examples of high and low signal strengths Automower from ™...
  • Page 13 If the Automower does not find the right loop signal strength when it leaves the charging station to follow the loop to a remote area, it will start to mow directly instead.

  • Page 14: Corridor Width

    3012-611 The longer the guide loop the lower the signal strength and the harder it is for the Automower to follow the guide wire. A lower signal strength means that the mower, with a given corridor width, will be run closer to the guide wire.
  • Page 15 In general the widest possible corridor should always be used. Apart from a reduced risk of tracks forming, it is also easier for the Automower to follow the boundary wire or guide wire. The mower does not need to stop as frequently to search for the signal and with that runs more smoothly.

  • Page 16: Search Method To Find The Charging Station

    Automower to pass through a passage is presented. Note that the values are approximate and can always vary in different installations. Table 5: Greatest possible corridor width for the Automower to pass through a specific passage Width of Version 02.32 2004 Version 02.32 2005...

    When charging starts the battery temperature should not be more than 40 ºC. Now let the Automower mow in manual operating mode until the battery is fully discharged. It is also possible to switch the mower from automatic to manual operating mode when it has left the charging station and started to mow.
