6. Maintenance
To maintain the appearance and integrity of your JEKCA sculpture:
- Cleaning: Dust the sculpture regularly with a soft, dry cloth. For deeper cleaning, gently wipe with a damp cloth and mild soap, then dry thoroughly. Avoid harsh chemicals or abrasive materials.
- Storage: If disassembling for storage, keep all bricks and pins organized to prevent loss. Store in a cool, dry place away from direct sunlight to prevent material degradation.
- Handling: While sturdy, avoid dropping or applying excessive force to the assembled sculpture to prevent bricks from detaching.
7. Troubleshooting
- Bricks Not Fitting: Ensure you are using the correct bricks for each step as indicated in the manual. Verify that no debris is obstructing the connection points.
- Pins Not Locking: Make sure the pin is fully inserted before attempting to turn it 90 degrees with the pin driver. If resistance is met, do not force it; re-check brick alignment.
- Sculpture Feels Unstable: Double-check all pin connections. The patented interlocking system provides significant stability when correctly assembled. Ensure every required pin is in place and turned to lock.
- Missing Pieces: In the event of missing components, please contact JEKCA customer support with your product model number and details of the missing parts.
