4. Assembly Instructions (Setup and Building)
The nanoblock Kawai Grand Piano kit is designed for advanced hobbyists. The assembly process requires patience and attention to detail. Refer to the separate, detailed step-by-step instruction booklet included in your package for precise building guidance.
4.1 General Tips for Assembly
- Organize Your Blocks: Due to the small size of nanoblocks, it is highly recommended to sort your pieces by color and shape before you begin. This will significantly speed up the building process.
- Work on a Clean, Flat Surface: A well-lit, stable surface will prevent pieces from getting lost or the model from being accidentally knocked over during construction.
- Follow Instructions Carefully: Each step in the provided instruction booklet is crucial. Pay close attention to the orientation and placement of each block.
- Use Tweezers (Optional): For very small or hard-to-reach placements, a pair of fine-tipped tweezers can be helpful.
- Patience is Key: This is a detailed model. Take breaks if you feel frustrated, and return to it with fresh eyes.

4.2 Building Process Overview
The instruction booklet will guide you through constructing the base, body, keys, lid, pedals, and the accompanying stool. Each section is broken down into manageable steps. Ensure blocks are firmly pressed together to create a stable structure.
5. Display and Care (Operating)
Once assembled, your nanoblock Kawai Grand Piano is a display model. While durable, it is not intended for rough play.
5.1 Display
- Place your finished model on a stable, flat surface away from direct sunlight and extreme temperatures to prevent discoloration or warping.
- Consider a display case to protect it from dust and accidental damage.
5.2 Cleaning
- To clean, gently dust the model with a soft brush or a can of compressed air.
- Avoid using liquid cleaners or abrasive materials, as these can damage the blocks.
6. Troubleshooting
- Missing Pieces: While rare, if you find a piece missing, first double-check your work area and packaging. If still missing, contact nanoblock customer support (see Section 8).
- Model Instability: Ensure all blocks are pressed firmly together. Re-examine the instruction steps for any missed or incorrectly placed blocks.
- Difficulty Connecting Blocks: Apply gentle, even pressure. If a block is particularly stubborn, try rotating it or checking for any debris in the studs or holes.
