8. Troubleshooting
If you encounter issues with your SFGSUP Wireless Tire Inflator, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inflator does not turn on. | Low battery or no charge. | Charge the device fully using the USB-C cable. |
| No air comes out during inflation. | Hose not securely attached; nozzle blocked; incorrect mode selected. | Ensure hose and adapter are tightly connected. Check for obstructions in the nozzle. Verify the correct inflation mode is selected. |
| Inflator stops prematurely. | Preset pressure reached; device overheated. | This is normal if the preset pressure is met. If not, allow the device to cool down for 10 minutes. |
