4. Assembly Instructions
The JEKCA building system utilizes a patented interlocking brick-through technology, ensuring a sturdy and durable model. Follow the detailed steps in the included instruction manual for precise assembly.
4.1 Understanding the Interlocking System
Unlike traditional building blocks, JEKCA bricks are secured using pins and a pin driver. This method creates a strong bond between layers, preventing the model from easily breaking apart.

4.2 General Assembly Steps
- Preparation: Unpack all components and organize them by color and shape if desired. Refer to the included Quick Guide for initial sorting tips.
- Follow the Manual: The primary instruction manual provides step-by-step diagrams for each layer of the model. Carefully follow the sequence.
- Insert Pins: For each connection point indicated in the manual, insert a pin into the designated hole.
- Secure Bricks: Use the provided pin driver to turn the inserted pin 90 degrees. This action expands the pin within the brick, creating a secure lock. Ensure each pin is fully turned for maximum stability.
- Layer by Layer: Continue building layer by layer, ensuring all pins are correctly inserted and turned before proceeding to the next section.
- Verify Connections: Periodically check that previously assembled sections are firm and stable.

5. Usage
Once fully assembled, your JEKCA Black Cat model is intended for display. Its sturdy construction allows for handling, but it is not designed as an active play toy, especially for younger children.
- Display: Place your finished model on a stable surface away from direct sunlight or extreme temperatures.
- Handling: Handle the model by its base or sturdy sections to avoid putting undue stress on individual components.
6. Maintenance
To keep your JEKCA model in excellent condition, follow these simple maintenance guidelines:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For more stubborn dirt, lightly dampen a cloth with water (no harsh chemicals) and gently wipe the surface.
- Avoid Liquids: Do not submerge the model in water or expose it to excessive moisture.
- Storage: If storing the model, ensure it is in a clean, dry environment, protected from dust and physical impact.
7. Troubleshooting
If you encounter issues during assembly or with your finished model, refer to these common solutions:
- Difficulty Inserting Pins: Ensure the pin is correctly aligned with the hole. Do not force pins; if resistance is met, check for obstructions or misaligned bricks.
- Loose Connections: If a section feels loose, verify that all pins in that area have been fully turned 90 degrees with the pin driver.
- Missing Parts: Carefully re-check the packaging and all components. If a part is genuinely missing, contact JEKCA customer support with your product model number and a description of the missing part.
- Assembly Errors: If you realize an error was made several steps back, carefully reverse the steps to correct it. The interlocking system is designed to be disassembled if needed, though it requires careful use of the pin driver to unlock pins.
