8. Troubleshooting
- Device does not turn on:
- Ensure the device is charged. If it has been stored for a long time, it might require a full charge cycle.
- Vehicle does not start:
- Check that the smart clamps are correctly connected to the battery terminals (red to positive, black to negative). Ensure the jump starter has sufficient charge (above 50%). If the smart clip shows an error, refer to its indicator guide in the full manual.
- Compressor does not start:
- Ensure the device is turned on and the desired pressure is set. Check that the air hose is securely connected. The compressor may enter protection mode if used continuously for too long; allow it to cool down.
- Device goes into protection mode:
- The smart clamps have built-in protections. This could be due to short circuit, reverse polarity, over-current, or high temperature. Disconnect all connections, allow the device to cool, and re-attempt operation following instructions carefully.
