Possible Causes
How to Fix / Troubleshooting
Safety first: Immediately turn OFF the mower, remove the battery, and move it to a non‑flammable surface. Do not continue to operate until inspected.
- Inspect for visible damage: Open the housing and look for burnt wires, melted insulation, or scorched PCB areas.
- Check motors: Smell each motor (blade and drive). A strong burnt odor from one indicates internal failure.
- Verify free movement: Ensure the blade disc and wheels rotate freely; clear any obstructions.
- Do not bypass fuses: If an internal fuse has blown, do not replace it without finding and fixing the root cause.
When to call a technician: Overheating and burning smells indicate serious faults. Replace the affected motor and inspect the PCB. If you are not experienced with electronics, seek professional service.
