Assembly Instructions
The JEKCA building system uses a unique interlocking method with pins to create sturdy structures. Follow the steps below for proper assembly.
Step 1: Understanding the Interlocking System
JEKCA blocks are designed to interlock securely using pins. This system ensures that your finished model is robust and less prone to falling apart compared to traditional building blocks.

Step 2: General Assembly Process
- Connect Blocks: Place one JEKCA block on top of another, aligning the studs and holes.
- Insert Pins: Insert the provided pins into the designated holes on the top block, ensuring they pass through to the bottom block.
- Secure with Pin Driver: Use the pin driver to turn each pin 90 degrees. This action expands the pin within the blocks, creating a strong, secure connection.
- Repeat: Continue this process, following the specific instructions in your included Quick Guide and detailed Instruction Manual, layer by layer, until your model is complete.

Maintenance
To keep your JEKCA model clean, gently wipe it with a dry, soft cloth. For more stubborn dust or dirt, a slightly damp cloth can be used. Avoid harsh chemicals or abrasive cleaners, as these may damage the plastic.
Troubleshooting
- Blocks not fitting: Ensure you are using the correct blocks as indicated in the instruction manual. Verify that no debris is obstructing the connection points.
- Pins not securing: Make sure the pins are fully inserted before turning them 90 degrees with the pin driver. If a pin feels loose, try removing it and re-inserting it carefully.
- Model feels unstable: Double-check all connections to ensure pins are properly inserted and turned. The JEKCA system is designed for sturdiness, so instability usually indicates an unsecured connection.
- Missing parts: If you find any missing components, please contact JEKCA customer support for assistance.
