Automatic Boring/Facing Head (Somewhat OT)

Guys,
I just bought one of these heads from Enco, anticipating using it
to machine larger diameter holes for motor mounts and in power supply
enclosures, for my Proxxon CNC conversion. Wouldn't you know, that
it's shipped with absolutely no instructions. I can sort of figure out
the basics, but it would be nice to know that I'm doing it right,
before I end up wrapping my work around the quill. Can anybody point
me in the direction of some instructions?

Thanks,
