Setup and Preparation
- Unpack Components: Carefully open the packaging and remove all nanoblock pieces and the instruction manual.
- Organize Pieces: It is recommended to sort the blocks by color and size before beginning assembly. This will simplify the building process.
- Clear Workspace: Ensure you have a clean, flat, and well-lit surface to work on to prevent losing small pieces.
Assembly Instructions
The nanoblock NBC-340 Arc de Triomphe set includes a detailed, step-by-step instruction manual. Follow these instructions carefully to ensure correct assembly.
- Step-by-Step Guidance: Refer to the included printed manual for visual and textual instructions for each building stage.
- Layered Construction: nanoblock models are typically built in layers. Pay close attention to the orientation and placement of each block as indicated in the manual.
- Secure Connections: Ensure each block is firmly pressed into place to create a stable structure.
- Review Each Step: Before proceeding to the next step, verify that your current assembly matches the illustration in the manual.
Note: Due to the small size of nanoblocks, precision and patience are key during assembly.
Care and Maintenance
- Cleaning: To clean your assembled nanoblock model, gently wipe it with a dry, soft cloth. For stubborn dust, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store unassembled blocks in their original packaging or a sealed container to prevent loss and dust accumulation. Keep assembled models in a stable location away from direct sunlight and extreme temperatures to prevent material degradation.
- Handling: Handle the assembled model with care to avoid accidental disassembly, especially with delicate sections.
Troubleshooting
- Missing Pieces:
- Carefully check the packaging and your workspace. Small nanoblocks can be easily overlooked. If pieces are genuinely missing, contact nanoblock customer support.
- Difficulty Connecting Blocks:
- Ensure blocks are correctly oriented and aligned. Apply firm, even pressure. Avoid forcing blocks, as this can damage them.
- Model Instability:
- Re-examine previous steps in the instruction manual. Ensure all blocks are securely connected and that the structure is built according to the design. Incorrect placement of even a single block can affect overall stability.
