3. Maintenance
To ensure the longevity and proper function of your CaDA building kit, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to gently wipe away dust. For stubborn dirt, a slightly damp cloth can be used, but ensure no water enters the internal mechanisms.
- Storage: Store the assembled model or unbuilt pieces in a cool, dry place away from direct sunlight and extreme temperatures to prevent material degradation.
- Handling: Handle the model with care to avoid accidental disassembly or damage to delicate parts.
4. Troubleshooting
If you encounter any issues during assembly or operation, please refer to the following common solutions:
- Missing Pieces: If you find any pieces missing during assembly, please contact CaDA customer support as detailed in the Warranty and Support section. Provide the model number (C52021W) and a description of the missing part.
- Difficulty Assembling: Review the instruction manual carefully. Ensure that pieces are oriented correctly and fully pressed into place. Some connections may require firm pressure.
- Pull-Back Motor Not Functioning: Check that the pull-back mechanism is correctly assembled and free from obstructions. Ensure the wheels are securely attached and can rotate freely.
- Car Does Not Move Straight: Verify that all wheels are aligned and attached properly. Uneven pressure during assembly can sometimes cause slight misalignment.
