Looking for old Heller 1500 parts list and/ or manual

We still have an old Heller 1500W kicking around and I can't locate a parts list or manual. I know some "spring cleaning" went on and I'm wondering if someone tossed them.

The main issue is the edge rail chains seem to suddenly have a lot of slack. The teeth on the sprockets are worn down, but I don't see how that would cause this much slack. It's not like the diameter of the sprocket changes much with worn out teeth.

We want to replace all of the sprockets and see where we end up.
