Tips for Assembly:
- Work systematically, completing one step before moving to the next.
- Double-check each connection to ensure blocks are firmly attached.

Care and Maintenance
To ensure the longevity and appearance of your CADA 61505W model, follow these care instructions:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For stubborn dirt, lightly dampen a cloth with water (no harsh chemicals) and gently wipe the surface.
- Storage: Store the model in a cool, dry place away from direct sunlight to prevent discoloration or material degradation.
- Handling: Handle the model carefully, especially when moving it, to avoid accidental disassembly of small parts.
- Avoid Extreme Temperatures: Do not expose the model to extreme heat or cold, as this can affect the plastic material.
Troubleshooting
Missing Parts
In the rare event that you discover missing parts during assembly:
- Carefully review the paper instruction manual and identify the exact missing pieces.
- Circle the missing parts on the manual's diagram.
- Contact customer support (refer to the Warranty & Support section) with a clear description or image of the circled missing parts for free replacement.
Assembly Difficulties
- Blocks not fitting: Ensure you are using the correct pieces as indicated in the manual. Sometimes similar-looking pieces have subtle differences. Apply gentle, even pressure when connecting blocks.
