LEGO System 6109 Building Instructions

To verify all pieces are included, use the inventory list provided in the instruction manual. Match each piece with the list to ensure none are missing.
If a piece is missing, contact LEGO customer service with the set number and missing piece information to request a replacement.
Clean LEGO pieces by hand using a soft cloth or sponge with mild soapy water. Avoid using a dishwasher or washing machine as high heat can deform the pieces.
Use a LEGO brick separator tool to gently pry apart pieces, minimizing stress on the bricks and reducing the risk of damage.
Store your LEGO set in a cool, dry place away from direct sunlight. Use compartmentalized storage bins to organize pieces by size and color.
Ensure all connections are secure by pressing bricks firmly together. Check the instruction manual to confirm that all pieces are used correctly.
Compare the shapes and sizes of the pieces with the diagrams in the manual, as lighting conditions can affect color perception.
For added stability, consider reinforcing key structural areas with additional supporting bricks not originally included in the design.
Ensure the surfaces are clean and free of dust before applying stickers. If issues persist, contact LEGO support for replacement stickers.
Designate a specific play and storage area for your LEGO set to minimize loss. Use resealable bags or small containers to store tiny pieces securely.
