Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | Battery is depleted or not properly inserted. | Charge the battery or ensure it is securely connected. |
| Pump runs but does not inflate. | Hose or nozzle not properly connected; valve on inflatable is closed or faulty. | Check all connections for leaks. Ensure the inflatable's valve is open and functioning correctly. |
| Pump stops prematurely. | Preset pressure reached; pump overheating. | Check the preset pressure. Allow the pump to cool down if it feels hot. |
| Inaccurate pressure reading. | Sensor obstruction or calibration issue. | Ensure no debris is blocking the sensor. If issues persist, contact customer support. |
| Battery drains quickly. | Old battery; frequent high-pressure use. | Consider replacing the battery if it's old. High-pressure inflation consumes more power. |
