How to Fix / Troubleshooting
Safety first: Turn OFF the mower before inspection.
- Check battery plug: Open the battery compartment and reseat the battery connector firmly.
- Verify full charge: Leave the mower on the charging station until the display or indicator shows 100% charge, then test again.
- Inspect vents: Clean any blocked ventilation openings to improve cooling.
- Load test battery: If available, use a battery tester or have a dealer perform a load test. Replace the battery if voltage drops excessively under load.
If shutdowns continue, the main PCB or internal temperature sensors may be failing and require professional diagnosis.
