The core of JEKCA's stability lies in its patented interlocking brick-through system. This involves inserting pins through the bricks to firmly connect them, preventing accidental disassembly.

4.2 Step-by-Step Assembly
- Unpack Components: Carefully open the box and sort the bricks by color and type if desired. Familiarize yourself with the pin driver and pins.
- Follow the Manual: Refer to the included detailed building manual for specific step-by-step instructions for the Giraffe 01S model. Each step will show which bricks to use and where to place the pins.
- Connect Bricks: Place the first brick(s) as indicated in the manual. Align the next brick(s) on top or adjacent to the previous ones.
- Insert Pins: Insert the provided pins through the designated holes in the bricks. Ensure the pins pass through both connecting bricks.
- Secure with Pin Driver: Use the pin driver to turn the pins 90 degrees. This action locks the bricks firmly in place. Repeat this process for all connections.
- Verify Connections: After each section, gently test the connections to ensure they are secure. If a section feels loose, re-check the pin placement and rotation.

6. Maintenance
Once assembled, your JEKCA Giraffe 01S model requires minimal maintenance.
- 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.
- Storage: If disassembling for storage, keep all bricks and pins organized in a container to prevent loss. Store in a cool, dry place away from direct sunlight to prevent material degradation or color fading.
- Handling: While sturdy, avoid dropping the model or applying excessive force, as this could cause individual bricks to detach or pins to loosen.
7. Troubleshooting
Here are solutions to common issues you might encounter during assembly:
- Loose Connections: If a brick feels loose, ensure the pin is fully inserted and rotated 90 degrees with the pin driver. Sometimes, a slight adjustment or re-insertion of the pin is needed.
- Missing Pieces: Double-check all packaging and work area. If you believe a piece is genuinely missing, contact JEKCA customer support with your model number and purchase details.
- Difficulty Inserting Pins: Ensure the bricks are perfectly aligned. The pins should slide in smoothly. Do not force pins, as this can damage the bricks or pins.
- Incorrect Placement: If you realize a section was built incorrectly, carefully use the pin driver to unlock the pins and disassemble the section. Re-assemble according to the manual.
