Possible Causes

Boundary wire laid too far from edges, Wire not secured and moved by soil or animals, Incorrect connection of boundary ends at station, Strong external magnetic fields

How to Fix / Troubleshooting

Safety first: Turn off the mower and unplug the charging station before adjusting the boundary wire.

  • Verify wire distance: Measure the distance from the boundary wire to the lawn edge. Adjust to AL-KO's recommended spacing (often 20–35 cm depending on edge type).
  • Secure wire: Use additional pegs to secure the wire, especially near slopes and edges where it may move.
  • Check connections: Ensure the boundary wire ends are correctly connected to the designated terminals on the charging station.
  • Avoid interference: Keep the boundary wire away from metal fences, buried cables, or other robotic mower wires that can distort the field.
  • Test perimeter: Run a perimeter test mode if available to confirm the mower follows the boundary correctly.
