5. Operating (Display and Handling)

6. Maintenance
To keep your JEKCA sculpture in optimal condition, follow these simple maintenance guidelines:
- 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.
- Avoid Chemicals: Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the plastic bricks and colors.
- Storage: If disassembling for storage, keep all bricks and pins organized in a container to prevent loss.
7. Troubleshooting
If you encounter any issues during assembly or with your finished model, consider the following:
- Missing Pieces: Carefully check all packaging and the work area. If pieces are genuinely missing, contact JEKCA customer support with your product model number and details of the missing parts.
- Difficulty Connecting Bricks: Ensure the pins are aligned correctly with the holes. Apply firm, even pressure with the pin driver. Do not force pins if they are misaligned, as this can damage the bricks.
- Model Instability: Review the assembly steps, particularly those involving the base and core structure. Ensure all pins are fully inserted and that bricks are correctly oriented and connected as per the manual.
