Setup and Assembly
The JEKCA Hen 01S model is assembled using a unique interlocking brick-through system, which ensures the stability and durability of the final structure. Follow the steps outlined in the included detailed instruction manual for precise assembly.

Operating (Display and Handling)

- Display: Place the model on a flat, stable surface away from direct sunlight or extreme temperatures.

Maintenance
To keep your JEKCA Hen 01S model in excellent condition:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For more stubborn dirt, a slightly damp cloth can be used, but avoid excessive moisture.
- Storage: If disassembling for storage, keep all bricks and pins organized to facilitate future reassembly. Store in a cool, dry place.
Troubleshooting
If you encounter any issues during assembly or with the stability of your model, consider the following:
- Loose Connections: Ensure all pins are fully inserted and rotated 90 degrees with the pin driver. A properly locked pin will feel secure.
- Missing Pieces: Double-check the packaging and your workspace for any small, overlooked bricks or pins. If pieces are genuinely missing, contact JEKCA customer support.
- Assembly Errors: Review the instruction manual carefully. Sometimes a small error in an early step can affect later sections. Carefully backtrack and correct any misaligned bricks.
