Robot mower leaves the lawn area and crosses the boundary wire.

Safety first: Turn OFF the mower before adjusting the boundary.

Steps:

• 1. Re-peg wire: Ensure the Yard Force boundary wire is pegged close to the ground with no loops sticking up.
• 2. Check for repairs: Inspect all previous wire joins; poor connections can distort the signal.
• 3. Reduce interference: Move the wire away from metal fences or buried power cables.
• 4. Test boundary sensor: If the mower still crosses the wire, test and replace the boundary sensor coil as needed.
