Maintenance
To ensure the longevity of your LEGO set, follow these maintenance guidelines:
- Cleaning: Use a soft brush or cloth to gently remove dust. For deeper cleaning, wash LEGO bricks with mild soap and lukewarm water (not exceeding 40°C / 104°F). Rinse thoroughly and air dry. Avoid harsh chemicals or hot water, as these can damage the plastic.
- Storage: Store the assembled model or individual bricks in a cool, dry place away from direct sunlight to prevent discoloration and warping.
- Handling: Handle the model with care, especially articulated parts, to prevent accidental disassembly or damage.
Troubleshooting
If you encounter any issues with your LEGO NINJAGO Movie Green Ninja Mech Dragon, consider the following:
- Missing Pieces: If you discover any missing pieces during assembly, please contact LEGO Customer Service directly for assistance.
- Loose Connections: Ensure all bricks are firmly pressed together according to the instructions. Sometimes, a loose connection can affect the stability or functionality of articulated parts.
- Functionality Issues: If a feature like the tail mechanism or stud shooters is not working correctly, re-examine the relevant assembly steps in the instruction manual to confirm correct construction.
