Robot mower occasionally runs outside the intended lawn area or crosses paths it should not

Safety: Turn OFF the mower before adjusting boundary wire.

• Check wire depth: Ensure the Makita boundary wire is pegged firmly to the ground or buried shallowly as recommended.
• Avoid metal structures: Keep boundary wire at the distance specified from metal fences, grids, or buried cables.
• Secure stakes: Add more pegs where the wire has lifted, especially on slopes or around corners.
• Interference sources: Identify and, if possible, move or shield devices that may emit strong electromagnetic fields near the lawn.

If the mower still crosses the boundary with a correct installation, the boundary sensor in the mower may be weak or faulty.
