3. Assembly Instructions
The JEKCA building system uses a unique interlocking method to create highly stable and durable models. Follow these steps carefully for successful assembly.
3.1 Understanding the Interlocking System
Unlike traditional building blocks, JEKCA blocks are secured using pins and a pin driver (screwdriver). This system ensures that your model is sturdy and less prone to falling apart.

3.2 General Assembly Steps
- Organize Components: Sort your bricks by color and size. This will significantly speed up the building process.
- Follow the Manual: Refer to the included detailed building manual for step-by-step instructions specific to the Lemur 01S model. Each step will indicate which bricks and pins to use.
- Connect Bricks: Place the designated bricks together according to the manual. Ensure they are properly aligned.
- Insert Pins: Insert the provided pins into the designated holes to connect the bricks.
- Secure with Pin Driver: Use the pin driver to turn each pin 90 degrees. This action expands the pin within the blocks, creating a secure, interlocking connection.
- Verify Connections: After securing a section, gently test the connection to ensure it is firm. If a connection feels loose, re-check the pin insertion and rotation.

4. Display and Care
4.1 Displaying Your Model
Once assembled, your JEKCA Lemur model is a durable display piece. Place it on a stable, flat surface away from direct sunlight and extreme temperatures to preserve its color and structural integrity.

4.2 Cleaning and Maintenance
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 immediately by a dry cloth. Avoid using harsh chemicals or abrasive materials, as these can damage the plastic.
The interlocking system makes the model sturdy, but excessive force or dropping can still cause damage. Handle with care.
5. Troubleshooting
- Loose Connections: If a section feels loose, ensure the pins are fully inserted and rotated 90 degrees. Sometimes, a pin may not be fully turned.
- Missing Pieces: Carefully check all packaging materials. If you believe a piece is genuinely missing, please contact JEKCA customer support with your model number and details of the missing part.
- Difficulty Inserting Pins: Ensure the blocks are perfectly aligned. Do not force pins; gentle pressure and correct alignment are key. The pin driver should turn smoothly.
- Disassembly: To disassemble, use the pin driver to turn the pins back 90 degrees to their original position, then gently pull the blocks apart. Avoid excessive force.
