8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on | Low or depleted battery | Charge the device fully using the provided Type-C cable. |
| Slow inflation or no inflation | Inflation hose not securely connected; Air leakage; Incorrect pressure setting; Low battery | Ensure hose is tightly screwed onto both the inflator and the valve stem. Check for any visible leaks. Verify the target pressure is set correctly. Recharge the device. |
| Inaccurate pressure reading | Hose not properly connected to valve stem | Ensure the nozzle is firmly attached to the valve stem without any angle or looseness. |
| Device overheats during use | Prolonged continuous operation | Allow the device to cool down for at least 10-15 minutes before resuming operation. Avoid continuous use for more than 10 minutes. |
