LEGO 21136-4 Building Instructions

Start by sorting all the pieces by color and type to make assembly easier. Follow the step-by-step instructions provided in the manual. If you lose the manual, you can download a PDF version from the LEGO website.
Check all packaging thoroughly to ensure the piece is not overlooked. If it is indeed missing, contact LEGO customer service through their website to request a replacement.
To maintain your set, keep it away from direct sunlight and excessive heat. Regularly dust the pieces and store them in a cool, dry place. Consider using a display case to protect from dust and physical damage.
Yes, LEGO sets are designed to be compatible with each other, allowing you to combine them and create custom builds. Ensure you have a stable base if you plan to integrate multiple sets.
Clean LEGO bricks by soaking them in warm water with mild soap. Use a soft brush to scrub any stubborn dirt. Avoid using a dishwasher or washing machine as high heat can warp the pieces.
Ensure all pieces are correctly aligned and fully connected. Double-check the instruction manual for proper assembly. For loose connections, gently press the pieces together again or consider using a LEGO-compatible adhesive for a more permanent hold.
Ensure that the surface is clean and dry before reapplying the sticker. If it continues to peel, consider using a small amount of clear adhesive to secure the edges.
To improve stability, ensure the base is broad and well-supported. Use larger plates to connect sections and consider reinforcing the build with additional bricks if necessary.
Yes, you can motorize parts of the set using LEGO Power Functions or LEGO Technic motors. Check the compatibility of the motor with the set and follow the instructions for installation.
Use a LEGO brick separator to gently pry apart bricks without damaging them. Sort the pieces into bags by type or color to make reassembly easier. Store the pieces in a durable container to protect them from dust and loss.
