Query: assembly instructions are useless

The photographs in the manual are poor quality. It seemed that the provided tools were not needed, but that can't be right. Can't widen the base. The instructions often don't match the actual product. No instructions or photographs regarding how to use the sling. This might be a good product, but I still haven't figured out how to safely use it. BTW, I have a Masters in Manufacturing Engineering.
