8. Troubleshooting
If you encounter issues with your ThiEYE Airkit 3, refer to the following common problems and solutions:

|---|---|---|
| Inflator does not turn on. | Battery is depleted or not properly inserted. 12V adapter not connected or car outlet is faulty. | Charge the battery or ensure it is securely inserted. Check 12V connection and car outlet. Try a different power source. |
| Inflator runs but does not inflate. | Air hose not securely connected. Valve adapter not properly attached to item. Hose or chuck is damaged. | Ensure air hose is tightly screwed onto the inflator. Re-attach valve adapter firmly. Inspect hose and chuck for leaks or damage. |
| Inaccurate pressure reading. | Minor calibration variance. | It is recommended to verify pressure with a separate, calibrated pressure gauge for critical applications. Adjust preset pressure accordingly based on observed variance. |
| Inflator stops prematurely. | Preset pressure reached. Overheating protection activated. | Check the preset pressure setting. Allow the unit to cool down for several minutes before resuming operation. |
If the problem persists after attempting these solutions, please contact ThiEYE customer support.
