5. Display and Operation
Once assembled, your Nanoblock Christmas Tree is ready for display.
- Placement: Place the model on a flat, stable surface to prevent it from toppling over.
- Environment: Avoid placing the model in direct sunlight or near heat sources, which can cause the plastic to warp or fade over time.
- Interaction: This is a static display model. While durable, excessive handling or dropping may cause pieces to detach.
6. Maintenance
- Cleaning: To clean the model, gently dust it with a soft brush or a dry cloth. For more stubborn dirt, a slightly damp cloth can be used, but ensure no water seeps into the crevices.
- Storage: If disassembling for storage, keep all pieces in a sealed container to prevent loss. Store in a cool, dry place.
7. Troubleshooting
- Missing Pieces: If you find any pieces missing upon opening the package, please contact Kawada customer support with proof of purchase.
- Difficulty Connecting Blocks: Ensure blocks are aligned correctly before applying gentle pressure. Nanoblocks are designed for a snug fit. Avoid excessive force, which can damage the blocks.
- Model Instability: Double-check all connections to ensure blocks are fully seated. Refer to the instruction sheet to verify correct placement of foundational layers.
