6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Drill not turning on. | Not connected to power, faulty power source, or loose connection. | Ensure the cable is securely plugged into a working 5V power source. Try a different USB port or adapter. |
| Drill bit not rotating or rotating slowly. | Speed setting too low, bit not inserted correctly, or device clogged. | Increase the speed using the control knob. Re-insert the drill bit correctly. If the device gets clogged, it will turn off automatically after 20 seconds; clear the clog and restart. |
| Excessive heat during operation. | Prolonged continuous use, improper bit usage, or poor ventilation. | Allow the drill to cool down. Ensure you are not applying excessive pressure. The drill is designed for low heat dissipation, but continuous heavy use can generate heat. |
| Unusual noise or vibration. | Loose drill bit, damaged bit, or internal issue. | Check if the drill bit is securely inserted. Replace the drill bit if it appears damaged. If the issue persists, contact customer support. |
