How to Fix / Troubleshooting
Safety first: Press STOP and switch OFF the mower before opening covers.
- Inspect battery connection: Open the battery compartment and ensure the connector is tight and free of corrosion.
- Check main switch: Operate the main power switch several times to clean contacts and ensure it latches firmly.
- Clean vents: Remove grass and dust from cooling vents and around the main PCB to improve airflow.
- Monitor temperature: If the mower stops more often on hot days, reduce mowing time during peak heat.
If random stops continue, a failing PCB or sensor harness may need professional diagnosis.
