5. Operating the Model
The nanoblock Tower Bridge Deluxe Edition features movable bascules (the central sections of the bridge). Once assembled, these sections can be manually raised and lowered to simulate the real bridge's operation.
5.1. Raising the Bascules
Gently lift the central bridge sections upwards from the base. Apply even pressure to avoid dislodging any blocks. The sections are designed to pivot.
5.2. Lowering the Bascules
Carefully push the central bridge sections downwards until they rest flush with the main bridge deck. Ensure they are fully seated to maintain the bridge's structural integrity.

- Cleaning: Use a soft, dry cloth or a small, soft brush to gently remove dust from the model. Avoid using water or cleaning solutions, as these may damage the plastic or cause discoloration.
- Storage: Store the model in a cool, dry place away from direct sunlight to prevent fading or warping of the plastic blocks.
- Handling: Handle the model with care to prevent accidental disassembly. If parts become loose, reattach them firmly.
