To verify all pieces are included, cross-reference the parts list in the instruction manual with the contents of the box. If any pieces are missing, contact LEGO customer service for replacements.
Sort the LEGO pieces by color and type. Use small containers or trays to organize them, which can speed up the building process and reduce the chance of losing pieces.
Ensure you are using the correct piece by comparing it with the instruction manual. Check for any blockages or misalignments in the connections, and gently adjust the pieces as needed.
Contact LEGO customer support to order a replacement part. In the meantime, try to temporarily secure the broken piece with non-permanent adhesive or tape to continue building.
Use a LEGO brick separator tool to gently pry apart the pieces without applying excessive force, which can prevent damage and make the disassembly process smoother.
Clean LEGO bricks using warm water with mild detergent. Avoid high temperatures and ensure that the pieces are thoroughly dried before storage to prevent mold or warping.
Consider placing the completed set in a display case or on a shelf with a protective cover. Regularly dust the set with a soft brush or microfiber cloth to keep it clean.
Download a digital copy of the instruction manual from the official LEGO website, which provides PDFs for all sets, including LEGO 21128-2.
Ensure all pieces are firmly connected and consider using additional internal support structures if the design allows. Avoid placing the build in areas with high foot traffic or where it can be easily knocked over.
Recheck each step in the instruction manual to identify any missed or incorrect steps. Ensure all pieces are correctly oriented and securely attached, adjusting as necessary to match the picture.
