So, the first thing to check is if your lathe is the early or later type. The early ones had 1/2' pitch leadscrew, later versions had 3/8' pitch. Later versions have 10 positions, (as does the SAG 14). The early ones only have 6 positions on the central rotating selector. Later versions have A-B-C-D (as does the SAG 14). The early ones only have A-B-C on the left hand-most selector. The lathe in the brochure photos (above) is an early version. Note: there are early and late variations of the SAG 180 feeds/screw cutting gearbox. Regarding a manual, I have a pdf copy, in foreign languages, of a 21 page SAG 180 manual. Good to hear from another Graziano owner.
