Assembly Instructions
The JEKCA building system utilizes a special interlocking brick-through system. Each brick is secured with a pin, ensuring a stable and durable model. A detailed step-by-step manual is included in your package to guide you through the assembly process.
General Assembly Tips:
- Follow the included step-by-step manual carefully.
- For increased stability, especially in the initial layers, consider building two layers of bricks simultaneously before securing them with pins. This method helps to create a solid foundation.
- Use the provided pin driver to firmly insert the pins into the bricks. Ensure each pin is fully seated to maximize stability.
- Organize your bricks by color and size before starting to streamline the building process.

Care and Maintenance
- Cleaning: To clean your JEKCA model, gently wipe it with a soft, dry cloth. For more stubborn dust, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the assembled model in a stable location to prevent accidental falls. If disassembling for storage, keep all bricks and pins organized in a container to prevent loss.
- Handling: While JEKCA models are designed to be sturdy, avoid excessive force or dropping the model to prevent parts from detaching.
Troubleshooting
- Difficulty Connecting Bricks: Ensure the pins are aligned correctly with the holes in the bricks. Apply firm, even pressure. If a pin is bent, replace it with a new one.
- Loose Connections: If a section feels loose, check that all pins are fully inserted and that the bricks are properly interlocked. Re-inserting pins or adjusting brick placement may resolve the issue.
- Missing Pieces: In the rare event of missing pieces, please contact JEKCA customer support with details of the missing components.
