How to Fix / Troubleshooting
Safety first: Immediately turn OFF the mower and disconnect it from the charging station. Do not continue to operate if a burning smell is present.
- Visual inspection: After cooling, open accessible covers and look for discolored plastic, melted insulation, or scorch marks near motors and the main board.
- Reduce load: Raise the cutting height and avoid mowing very tall or wet grass. Exclude steep slopes beyond the mower's rating.
- Clean vents and deck: Remove built‑up grass from around the blade motor and ventilation openings to improve cooling.
- Check for free movement: Ensure the blade disc and wheels rotate freely without binding.
- Do not ignore persistent odor: If the smell returns, stop using the mower and have a Cedrus technician inspect the motors and electronics for damage.
