Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inflator does not turn on. | No power from 12V outlet; Blown fuse in plug. | Ensure 12V outlet is active (vehicle engine running). Check and replace the fuse in the power plug if necessary. |
| Inflator runs but does not inflate. | Air hose not securely connected; Valve stem blocked. | Ensure the air hose is tightly screwed onto the valve stem. Check for any obstructions in the valve. |
| Inaccurate pressure reading. | Poor connection to valve; Unit not calibrated. | Ensure a tight seal between the hose and valve. Compare reading with a known accurate gauge if possible. |
| Inflator stops prematurely. | Desired pressure reached; Overheating. | This is normal if the preset pressure is reached. If not, allow the unit to cool down for 10-15 minutes before resuming operation. |
