Assembly Instructions
The JEKCA building system utilizes a unique interlocking method for creating sturdy models. Follow the step-by-step diagrams provided in the instruction manual and refer to the general principles below.

Figure 1: Basic Interlocking System. This diagram illustrates the core principle of JEKCA assembly. First, insert a connecting pin through the top block and into the receiving hole of the bottom block. Second, use the pin driver tool to turn the pin 90 degrees, locking the blocks securely together. This method ensures the model is sturdy and resistant to breaking apart.

Figure 2: Step-by-Step Pin Connection. This image provides a clearer view of the interlocking process. Step 1: Insert the pin into the top block. Step 2: Align the pin with the hole in the lower block. Step 3: Use the pin driver to rotate the pin 90 degrees clockwise or counter-clockwise until it is firmly seated, creating a strong connection between the blocks.

Figure 3: Visual Guide to Block Interlocking. This graphic further illustrates the three key actions for connecting JEKCA blocks: 1. Placing blocks together, 2. Inserting pins, and 3. Rotating pins with the driver for a secure fit. This system ensures the structural integrity of your finished model.
General Assembly Tips:
- Follow the manual: Refer to the specific building manual included in your kit for the exact sequence of steps for the Calico Cat model.
- Layer by layer: JEKCA models are typically built layer by layer. Ensure each layer is complete and securely interlocked before proceeding to the next.
- Check connections: Periodically check that all pins are fully rotated and blocks are tightly connected to prevent instability.
- Patience is key: Building intricate models requires patience. Take breaks if needed to maintain focus and accuracy.
Maintenance
Once assembled, your JEKCA Calico Cat 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: Store the model in a stable location away from direct sunlight and extreme temperatures to prevent material degradation or discoloration.
- Handling: While sturdy, avoid dropping or applying excessive force to the model to prevent pins from dislodging or blocks from breaking.
Troubleshooting
- Model feels unstable or wobbly:
- Ensure all connecting pins are fully inserted and rotated 90 degrees. Revisit previous steps to confirm all blocks are securely interlocked.
- Difficulty inserting pins:
- Check for any debris in the pin holes. Ensure the blocks are perfectly aligned before attempting to insert the pin. Do not force pins; gentle pressure and proper alignment are key.
- Missing or damaged parts:
- If you find any missing or damaged parts upon opening the kit, please contact JEKCA customer support with your purchase details for assistance.
