8. Troubleshooting
8.1 Pump Not Turning On or Motor Not Starting
- Check the battery level. If the battery is low, charge the device fully.
- Ensure the power button is pressed and held for a few seconds to turn on.
- If the motor does not start, ensure the air tube is securely connected and the target pressure is set above the current pressure.
8.2 Battery Drains Quickly
