Assembly Instructions
The JEKCA building system utilizes a patented interlocking brick-through technology, ensuring a robust and stable structure without the need for glue.
Step 1: Understand the Interlocking System
Each brick is designed to interlock securely with others using pins.

Step 2: Follow the Building Manual
Refer to the included detailed instruction manual for step-by-step assembly. Each step will guide you on which bricks to use and how to connect them.
Step 3: Using the Pin Driver
The provided pin driver is essential for inserting and securing the pins:
- Insert a pin into the designated hole on the top brick.
- Align the top brick with the bottom brick.
- Use the pin driver to push the pin through the top brick and into the corresponding hole of the bottom brick.
- Rotate the pin driver 90 degrees to lock the pin in place, creating a strong bond between the bricks.

Care and Maintenance
To clean your JEKCA model, gently wipe it with a dry, soft cloth. For more stubborn dust, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive materials.
Store the model in a stable location to prevent accidental falls or damage.
Troubleshooting
- Difficulty Interlocking Bricks: Ensure the pins are correctly aligned and fully inserted before rotating with the pin driver. Apply gentle, even pressure.
- Loose Connections: If a section feels loose, re-examine the connections in that area. Ensure all pins are properly inserted and rotated 90 degrees.
- Missing Pieces: Carefully check all packaging materials. If pieces are genuinely missing, contact JEKCA customer support with your model number and details of the missing parts.
