Go to the LEGO website.
Scroll down to the bottom of the site and click "Building Instructions."
Enter the 4- or 5-digit set number. If you do not know the set number, search the database using keywords (e.g., "boat" or "shuttle") or specific brands (e.g., Batman or Indiana Jones).
Scroll through the search results under the "Select a building instruction" section at the bottom of the page to locate your desired set.
Click the desired LEGO set to view the file information. Each set has two versions of building instructions. Files labeled with "NA" or "V39" are designed for U.S. standard letter size paper. Files labeled with "IN" or "V29" are designed for EU standard A4 paper. Make sure to select the correct file label.

Click the "Save" button to save a copy of the instructions to your computer.
