6. Maintenance
To ensure the longevity and continued enjoyment of your SEMBO building block kits, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to gently wipe away dust and dirt. For stubborn grime, a slightly damp cloth can be used, but ensure no water enters any electronic components (if applicable). Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the assembled models or disassembled blocks in a cool, dry place away from direct sunlight and extreme temperatures. Keep them in a container or on a shelf to prevent loss of pieces.
- Handling: Handle models with care to avoid accidental disassembly or damage to delicate parts.
7. Troubleshooting
Most issues with building block kits can be resolved with simple checks:
- Missing Pieces: If you find any missing pieces during assembly, please contact the seller for assistance. Note that ordinary parts replace printed parts in MOC products.
- Loose Connections: If parts are not holding together firmly, gently re-press them to ensure a secure connection. Check the electronic manual to confirm correct placement.
- Model Instability: Ensure all connections are tight and that the model is built according to the instructions. Incorrect assembly can lead to instability.
- Remote Control Issues (if applicable): Check battery levels in both the remote and the model. Ensure proper pairing according to the remote control kit's instructions.
