5. Operating Principles
The JEKCA building blocks operate on a unique interlocking principle. Unlike traditional friction-fit blocks, JEKCA models are reinforced with small pins that are inserted into the studs of the bricks and then rotated. This rotation locks the pins into place, creating a secure and sturdy connection between individual bricks. This system prevents the model from easily falling apart, allowing for a robust and display-worthy finished product.
6. Maintenance
To ensure the longevity and appearance of your JEKCA Welsh Corgi Mini 01S model, follow these simple maintenance guidelines:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For more thorough cleaning, gently wipe with a damp cloth and mild soap, then dry immediately. Avoid harsh chemicals or abrasive materials.
- Storage: Store the model in a cool, dry place away from direct sunlight to prevent discoloration or material degradation.
- Handling: While the interlocking system makes the model sturdy, avoid dropping it or applying excessive force, which could cause parts to detach or break.
7. Troubleshooting
If you encounter any issues during assembly or with the stability of your model, consider the following:
- Bricks Not Staying Together: Ensure that the interlocking pins are correctly inserted and fully rotated 90 degrees using the pin driver tool. If a pin is not fully turned, the connection will not be secure. Double-check the instruction manual for the correct pin placement for each step.
- Missing Pieces: Carefully check all packaging materials. If you believe a piece is genuinely missing, refer to the support section for contact information.
- Difficulty with Pin Insertion: Ensure the pin is aligned correctly with the hole in the brick. Apply gentle, even pressure. The pin driver tool is designed to assist with this.
