Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inflator does not turn on. | No power connection or faulty fuse. | Ensure power cables are securely connected. Check and replace the fuse in the 12V DC plug if necessary. |
| Inflator runs but does not inflate. | Nozzle not securely attached or hose/nozzle blockage. | Ensure the nozzle is firmly attached to the valve. Check the hose and nozzles for any obstructions. |
| Inflator does not stop at preset pressure (for small items). | Digital gauge sensitivity for very low pressure ranges. | For very small items (e.g., some balls), manually monitor pressure and stop inflation when desired level is reached. The auto-stop feature is most accurate for larger volumes like tires. |
| Device becomes excessively hot. | Prolonged continuous operation. | Turn off the inflator and allow it to cool down for at least 10-15 minutes before resuming operation. Avoid continuous use for more than 10 minutes. |
