Service Manual for 1989 Atco Powered Sweeper

Hello, I'm wondering if anyone might happen to have a full copy of the service manual for a 1989 Atco Powered Sweeper. I've seen that there is a PDF containing only the exploded diagrams from it on this website however, I've recently acquired a sweeper and the manual that came with it is water damaged making it impossible to link some of the numbers on the diagrams with their part numbers.

I've contacted both the modern Atco and Bosch but neither of them have copies because it was made before either of those companies bought out Atco.

Any help would be greatly appreciated, thank you.
