Does anybody know of a website or a book that can help me learn how to use a rotary vise?

I've just acquired a used Renzetti Traveler. Have never tied with a rotary before. Clamped it into my tying tray and suddenly realized that I have no idea how to use a rotary or a bobbin cradle. I've tried the search function here and also Google, but I seem to be using the wrong key words.

Any leads for instructions most gratefully welcomed. Thanks!
