Assembly (Setup)
The JEKCA building system utilizes a unique screw-and-lock mechanism to create sturdy and durable models. Follow these steps carefully:
- Preparation: Unpack all components and organize your bricks by color and shape. Refer to the included Quick Guide for an overview of brick types.
- Connecting Bricks: Identify the first two bricks to be connected as per the instruction manual diagrams. Align the studs and holes.
- Inserting Pins: Insert a connecting pin into the designated hole, passing through both bricks. Ensure the pin is fully seated.
- Locking Pins: Use the provided pin driver tool to turn the pin 90 degrees. This locks the bricks securely in place, preventing the model from easily breaking apart. Repeat this process for all connections as indicated in the step-by-step diagrams.

Operating (Display and Interaction)
Once assembled, your JEKCA Jack Russell Terrier model is designed for display. Its sturdy construction, thanks to the locking pin system, allows for handling without easily falling apart. You can place it on shelves, desks, or other flat surfaces as a decorative piece.
While the model is robust, avoid excessive force or dropping it, as this may cause individual bricks to detach or pins to loosen. If any part becomes loose, re-insert and lock the pin as described in the assembly section.
Maintenance
To keep your JEKCA model clean and in good condition:
- Dusting: Use a soft, dry cloth or a soft-bristled brush to gently remove dust from the surface.
- Cleaning: For more stubborn dirt, lightly dampen a cloth with water and a mild soap solution. Gently wipe the affected areas, then dry immediately with a clean, dry cloth. Avoid harsh chemicals or abrasive cleaners.
- Storage: If disassembling for storage, keep all bricks and pins organized to prevent loss. Store in a cool, dry place away from direct sunlight to prevent material degradation or discoloration.
Troubleshooting
- Problem: Bricks are not connecting securely.
- Solution: Ensure the connecting pins are fully inserted and rotated 90 degrees with the pin driver. Verify that you are using the correct size and type of pin for the connection as indicated in the manual.
- Problem: Missing pieces.
- Solution: Carefully check all packaging materials. If pieces are genuinely missing, please contact JEKCA customer support with details of the missing parts (refer to the parts list in your manual).
- Problem: Difficulty understanding a specific assembly step.
- Solution: Review the diagram for that step closely. Sometimes, rotating the manual or looking at the next few steps can provide clarity. If still stuck, refer to online resources or contact customer support.
