7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | Low battery or power button not held long enough. | Charge the pump fully. Press and hold the power button for 3 seconds. |
| Pump inflates slowly or not at all. | Inflation tube not securely attached, valve core loose, or low battery. | Ensure all connections are tight. Check valve core for proper seating. Recharge the pump. |
| Pump stops before reaching target pressure. | Target pressure set too low, or internal safety mechanism activated due to overheating. | Verify target pressure setting. Allow pump to cool down if it has been running continuously for an extended period. |
| Inaccurate pressure reading. | Improper connection to valve, causing air leakage. | Ensure the inflation tube is firmly connected to the valve without any leaks. |
