3.5.1 Plan where to lay the boundary wireThe boundary wire must be laid so that:• The wire forms a loop around the working area. Useoriginal boundary wire. It is specially designed toresist dampness from the soil.• The robotic lawnmower is never more than 15 m / 49ft. from the wire at any point in the working area.• The wire is no more than 400 m / 1312 ft. long.• About 20 cm / 8 in. of extra wire is available to whichthe guide wire will be connected later. SeeLayingthe boundary wire on page 18.The illustration below shows how the boundary wiremust be laid around the working area and aroundobstacles. Use the supplied measurement gauge toobtain the correct distance. SeeProduct overview onpage 6.10 cm / 4"0 cm / 0"35 cm / 14"30 cm / 12"3.5.2 Working area boundariesDepending on what the working area is adjacent to, theboundary wire must be laid at different distances fromobstacles.If a high obstacle (5 cm / 2 in. or more), for example awall or fence, borders the working area, the boundarywire should be laid 30 cm / 12 in. from the obstacle. Thiswill prevent the robotic lawnmower from colliding withthe obstacle and reduce body wear. About 20 cm / 8 in.of the lawn around the fixed obstacle will not be mown.35 cm / 14"> 5 cm / 2"If the working area borders a small ditch, a flower bed ora small elevation, for example a low kerbstone (1-5 cm /0.4-2 in.), the boundary wire should be laid 20 cm / 8 in.inside the working area. This prevents the wheels fromdriving into the ditch or up onto the kerbstone whichmight be lead to excessive wear on the roboticlawnmower. About 12 cm / 5 in. of the lawn along theditch/kerbstone will not be mown.30 cm / 12"1-5 cm / 0.4-2"If the working area borders on a paving stone path orsimilar that is level with the lawn (+/- 1 cm / 0.4 in.), it ispossible to allow the robotic lawnmower to run a littleover the path. The boundary wire should then be laid 5cm / 2 in. from the edge of the path. All the grass alongthe side of the paving stone path will be cut.10 cm / 4"max 1 cm / 0.4"When the working area is divided by a paving stone paththat is level with the lawn, it is possible to allow therobotic lawnmower to run over the path. It can be anadvantage to lay the boundary wire under the pavingstones. The boundary wire can also be laid in the jointbetween the paving stones. Ensure that the tiles are inlevel with the lawn to avoid excessive wear on therobotic lawnmower.447 - 001 - Installation - 15
