SecondaryareaMain areaTheSecondary area operating mode must be used asthe robotic lawnmower cannot travel on its own from thesecondary area to the charging station. SeeOperatingmode - Start on page 43. In this mode, the roboticlawnmower will never look for the charging station butwill mow until the battery runs out. When the battery isflat, the robotic lawnmower will stop and theNeedsmanual charging message will appear in the display.Place the robotic lawnmower in the charging station tocharge the battery. If the main area has to be cutstraight after charging, the START button must bepressed and theMain area selected before closing thehatch.3.5.3.2 Passages when mowingLong and narrow passages and areas narrower than 1.5- 2 m / 3.2 - 6.5 ft. should be avoided. It is then a riskthat the robotic lawnmower travels around in thepassage or area for a period of time. The lawn will thenlook flattened. The narrowest possible passage for therobotic lawnmower is 60 cm / 24 in (between boundarywires).Note: In passages narrower than 2 m / 6.5 ft. (betweenboundary wires) Husqvarna recommends that a guidewire is installed.3.5.3.3 SlopesThe robotic lawnmower can operate in slopes. Themaximum gradient is defined as percentage units (%)and is calculated as difference in elevation incentimetres for every meter. Inside the working area therobotic lawnmower can mow areas which slope up to40%. Areas that slope more must be isolated with theboundary wire.The boundary wire can be laid across a slope that slantsless than 15%.0-15%0-15 cm / 0-6"100 cm / 40"The boundary wire should not be laid across a slope thatis steeper than 15%. There is a risk that the roboticlawnmower will find it difficult to turn there. The roboticlawnmower will then stop and theOutside working areafault message is displayed. The risk is at its greatest indamp weather conditions, as the wheels can slip on thewet grass.15- %>15 cm / >6"100 cm / 40"However, the boundary wire can be laid across a slopesteeper than 15% if there is an obstacle that the roboticlawnmower is allowed to collide with, for example, afence or a dense hedge.When a part of the working area’s outer edge slopesmore than 15%, the boundary wire must be laid about20 cm / 8 in. in on the flat ground before the beginning ofthe slope.840 - 001 - Installation - 15
