7. Troubleshooting

If you encounter issues with your AUTDER AD-380, please check the following:

• Device not turning on: Ensure the battery is fully charged and properly inserted, or that the 12V DC cable is securely connected to a working power source.
• No inflation: Check that the hose and nozzle adapter are securely attached to both the compressor and the item's valve stem. Ensure the target pressure is set above the current pressure.
• Slow inflation: Verify that the power source (battery or 12V DC) is providing sufficient power. Ensure there are no leaks in the hose or connections.
• Overheating: If the device feels excessively hot, stop operation and allow it to cool down. The internal cooling system should manage heat during normal use.
