This NERA model may be installed with a physical boundary wire or, where supported/configured, a wire-free EPOS setup. The correct diagnostic branch depends on the installation actually in use.

Start with these checks
- Isolate mower.
- Inspect EdgeCut blades and screws.
- Check blade placement.
- Replace damaged/worn blades.
- Retest.
- Switch off and safely isolate the mower.
Stop if: the mower has damaged wiring, a swollen/damaged battery, severe vibration, water inside electrical areas, or would require opening sealed electronics.
What this fault can mean
