Assembly Instructions
The JEKCA building system utilizes a unique interlocking brick-through system for enhanced stability. Follow these steps carefully for successful assembly.
- Preparation: Unpack all components and organize the building bricks by color and type if desired. Ensure you have the Pin Driver readily available.
- Layer-by-Layer Construction: Begin assembling the model according to the provided detailed instruction manual included in your box. Each step will illustrate which bricks to place.
- Interlocking System: For each layer, after placing the bricks, use the provided connecting pins to secure them. Insert a pin through the designated holes in the bricks.

- Securing Pins: Once a pin is inserted, use the Pin Driver to turn it 90 degrees. This action locks the bricks together, creating a sturdy and stable structure.

- Continue Building: Repeat the layering and pinning process until the model is complete. Refer to your physical instruction manual for specific brick placement and pin locations.
The interlocking system ensures that your finished model is robust and less prone to accidental disassembly compared to traditional building blocks.
Operating & Display

Maintenance
To keep your JEKCA model in optimal 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. Do not use harsh chemicals or abrasive cleaners.
