Operating the Model

Avoid applying excessive force to any part of the model to prevent breakage.
Maintenance
To keep your Maserati MC20 building set in optimal condition:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For more stubborn dirt, lightly dampen a cloth with water (no harsh chemicals) and gently wipe the surfaces.
- 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 pieces detaching.
Troubleshooting
If you encounter any issues during assembly or with your completed model, consider the following:
- Missing Pieces: Carefully re-check the packaging and assembly area. If a piece is genuinely missing, contact Mattel customer support (see 'Support' section).
- Difficulty Connecting Pieces: Ensure pieces are correctly oriented and aligned. Apply firm, even pressure. Avoid forcing pieces together, as this can cause damage.
- Model Instability: Review previous assembly steps to ensure all connections are secure and no pieces were missed or incorrectly placed.
- Decals Not Sticking: Ensure the surface is clean and dry before application. Press firmly on the decal after placement.
