How to Fix / Troubleshooting
Safety first: Switch OFF the mower and disconnect the charging station. Wear gloves when working near blades.
- Inspect for debris: Turn the mower upside down and remove any stones, branches, or compacted grass from around the cutting disc and deck.
- Check blade tightness: Ensure all blade screws are tight and blades can pivot freely. Replace any damaged screws or blades.
- Spin test: Rotate the cutting disc by hand. Listen for grinding or roughness, which indicates worn motor bearings.
- Replace worn parts: If noise persists after cleaning and tightening, replace the cutting disc and, if necessary, the blade motor assembly.
