OMG!! I've longed for a Stainless Roll 8 ever since the few that rolled off the assembly line did years ago. I still regularly browse/search for one.

The thing about bike manuals is that they all seem to come off the same original draft. Safety stuff, model-generic, and not much else. I think my electric-bike one is the only recent one that had any meaningful material, and even that was limited for what I had to know and learn. I still have the binders/manuals that came with my KAYPRO 10 and my HP Omnibook, but I don't remember bikes ever coming with good bike/model-specific manuals. I don't think you'll find a helpful manual anywhere for that Roll because one was never printed.
