5. Operating Instructions (Building Process)

The primary operation of this product is the building process itself. Engage with the model by following the provided manual's sequence. The interlocking system ensures that once a section is built and pinned, it remains stable, allowing for complex and durable structures.

• Patience is Key: Building intricate models requires patience and attention to detail.
• Organize Your Bricks: Sorting bricks by color or size can streamline the building process.
• Enjoy the Process: The satisfaction comes from the careful construction and the final, sturdy model.

6. Maintenance

To ensure the longevity and appearance of your JEKCA model:

• Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For deeper cleaning, gently wipe with a damp cloth and mild soap, then dry thoroughly. Avoid harsh chemicals.
• Storage: Store the assembled model in a stable location away from direct sunlight and extreme temperatures to prevent material degradation or discoloration.
• Disassembly: If you need to disassemble the model, carefully remove the pins using the Pin Driver. Avoid forcing bricks apart without first removing the pins to prevent damage.

7. Troubleshooting

• Difficulty Following Instructions: If the instruction pictures appear too small or unclear, try using a magnifying glass or taking a photo with your phone and zooming in. JEKCA manuals are generally detailed, but some steps may require closer inspection.
• Missing Pieces: While JEKCA typically provides extra pieces, if you find a critical piece missing, please contact JEKCA customer support with your product model number and details of the missing part.
• Model Not Sturdy: Ensure all pins are fully inserted and secured with the Pin Driver. The interlocking system relies on these pins for structural integrity. Re-check any wobbly sections to confirm proper pin placement.
• Pins Difficult to Insert/Remove: Apply gentle, consistent pressure. If a pin is stuck, ensure it is aligned correctly. The Pin Driver is designed to assist with this process.
