Congrats, and welcome to MV!
What you have is essentially a special edition Primavera 150. As far as I'm aware, all of the differences between that and the standard model are cosmetic. So pretty much anything that applies to a Primavera 150 is relevant to your bike.
I can't recall where most of the manuals are usually posted at the moment (can someone else help out, too?), but you'll be able to find a lot of good stuff in
the Wiki section here on MV.
Here's hoping you enjoy many happy miles.
