Lyn, I have the 1475cd, and I think they are similar. I'll have a look at my manual when I get home. All the patterns are on the lid, so I think you choose the pattern for overcasting, and set width and length buttons. I think the foot would be the one with the red wheel on it.
Lucky GD learning on such a lovely machine. I prefer my Pfaff to the Bernina, and hope it works for some time to come (fingers tightly crossed).
It's quite a thick manual, so unfortunately I can't copy all the pages, but I'll try to find relevant pages for you.
If it's urgent, send me a pm with your mobile number, and I'll photograph some pages for you. Failing that, I'll scan them on Monday, and send them through to your email address.
Jessie
