6. Maintenance
To ensure the longevity and appearance of your Cada building block model:
- Cleaning: Wipe the model gently with a soft, dry cloth. For stubborn dust, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the model in a cool, dry place away from direct sunlight and extreme temperatures, which can cause discoloration or warping of plastic parts.
- Handling: Handle the model with care. Avoid dropping it or applying excessive pressure, especially to movable parts.
7. Troubleshooting
If you encounter any issues with your Cada Super Sports Car, consider the following:
- Missing Parts: Double-check the packaging and all bags. If parts are genuinely missing, refer to the 'Warranty & Support' section for assistance.
- Difficulty Assembling: Review the instruction manual carefully, paying close attention to the diagrams. Ensure all pieces are correctly oriented and fully connected. Sometimes, a small misalignment can prevent larger sections from fitting.
- Pull-Back Function Not Working: Verify that the pull-back gearbox is correctly assembled and installed according to the instructions. Ensure there are no loose pieces obstructing the mechanism. The car needs a smooth, flat surface to operate effectively.
- Loose Connections: If parts feel loose, gently press them together to ensure a secure fit. Over time, repeated assembly/disassembly can slightly wear connections, but this is generally not an issue with initial builds.
