3.5.3.1 Secondary areas If the working area consists of two areas, which the robotic lawnmower has difficulty travelling between, it is recommended to set up a secondary area. Instances of this are 45% slopes or a passage that is narrower than 60 cm / 24 in. Lay the boundary wire then around the secondary area so that it forms an island outside of the main area. The robotic lawnmower must be moved manually between the main and secondary area when the lawn in the secondary area has to be cut. Secondary area Main area 3.5.3.3 Slopes The robotic lawnmower can operate in slopes. The maximum gradient is defined as percentage units (%) and is calculated as difference in elevation in centimetres for every meter. Inside the working area the robotic lawnmower can mow areas which slope up to 45%. Areas that slope more must be isolated with the boundary wire. The boundary wire can be laid across a slope that slants less than 15%. 0-15 0-15 cm/0-6" 100 cm / 40" The boundary wire should not be laid across a slope that is steeper than 15%. There is a risk that the robotic lawnmower will find it difficult to turn there. The robotic lawnmower will then stop and the Outside working area fault message is displayed. The risk is at its greatest in damp weather conditions, as the wheels can slip on the wet grass. 15- % >15 cm / >6" The Secondary area operating mode must be used as the robotic lawnmower cannot travel on its own from the secondary area to the charging station. See Operating mode - Start on page 40. In this mode, the robotic lawnmower will never look for the charging station but will mow for the chosen time or until the battery runs out. Place the robotic lawnmower in the charging station to charge the battery. If the main area has to be cut straight after charging, tap on Start in the Automower® Connect app and then select Resume on main area. 3.5.3.2 Passages when mowing Long and narrow passages and areas narrower than 1.5 - 2 m / 3.2 - 6.5 ft. should be avoided. It is then a risk that the robotic lawnmower travels around in the passage or area for a period of time. The lawn will then look flattened. The narrowest possible passage for the robotic lawnmower is 60 cm / 24 in (between boundary wires). Note: In passages narrower than 2 m / 6.5 ft. (between boundary wires) Husqvarna recommends that a guide wire is installed. 100 cm / 40" However, the boundary wire can be laid across a slope steeper than 15% if there is an obstacle that the robotic lawnmower is allowed to collide with, for example, a fence or a dense hedge. When a part of the working area's outer edge slopes more than 15%, the boundary wire must be laid about 20 cm / 8 in. in on the flat ground before the beginning of the slope. 362 - 002 - 06.02.2018 Installation - 17
