recommended to make an eyelet where the guide wire will be connected. Make the eyelet with approximately 20 cm / 8 in. of the boundary wire. > 5 cm / 2" 35 cm /14" • Put the boundary wire 30 cm / 12 in. (C) from an obstacle that is 1-5 cm / 0.4-2 in. high. Note: Make a blueprint of the work area before you install the boundary wire and guide wire. 30 cm / 12" E D F 1-5 cm / 0.4 - 2" • Put the boundary wire 10 cm / 4 in. (D) from an obstacle that is less than 1 cm / 0.4 in. high.
• Make an eyelet (F) where the guide wire is to be connected to the boundary wire. sure that the guide wire has as much free area as possible to the left of the guide wire. 3.4.3.1 To put the boundary wire in a slope The product can operate in 45% slopes.

with raised roots, must be isolated or removed. The product can run onto this kind of obstacle causing the blades to be damaged. Use the boundary wire to isolate areas inside the work area by creating islands. When the boundary wires to and from the island are put close together, the product can run over the wire. B Note: To achieve careful and silent operation, it is recommended to isolate all fixed objects in the work area. • • • Put the boundary wire to and around the obstacle to make an island.
D A 3.4.5 Work area examples • • • • • If the charging station is put in a small area (A), make sure that the distance to the boundary wire is at a minimum 3 m / 10 ft. in front of the charging station. If the work area has a passage (B), make sure that the distance to the boundary wire is at a minimum 2 m / 6.5 ft. If the passage is smaller than 2 m / 6.5 ft., install a guide wire through the passage. Minimum passage between the boundary wire is 60 cm / 24 in.
