- Nozzle Inspection: Periodically check the nozzles and air chuck for any damage or blockages. Clean as necessary.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on | Battery is discharged or not properly inserted. | Charge the battery fully. Ensure the battery is securely attached to the pump. |
| Pump runs but no air inflates | Air hose or nozzle is blocked, or not securely connected. | Check for blockages in the hose/nozzle. Ensure all connections are tight. |
| Inaccurate pressure reading | Loose connection to valve, or unit setting is incorrect. | Ensure the air chuck is tightly sealed on the valve. Verify the correct pressure unit is selected on the display. |
| Pump stops prematurely | Preset pressure reached, or battery is low. | This is normal if the preset pressure is reached. If not, check battery level and recharge if necessary. |
