If you don't have the manual you can download one from Singerco.co. I think the manual is a requirement for the Singer Slant-o-matics (400 and 500 series) and Touch & Sews (descended from the 400 and 500 series machines) if you want to get the full use out of your machine. They will do a lot but aren't really intuitive to use.
Congrats on your Rocketeer! If it sews as well as my 401A you'll love it.
Make sure you post the White too.
