I also think going into Husgvarna's own web site might help you alot.
ALSO, many of the dealers for Viking sells books esp. for your machine. No, not the manual... a real how-to on what can be done with your Viking model. I remember when we lived in Stuart FL, the dealer there had a wall of books for the machines. Perhaps if you google.com search of the LARGEST Viking Sewing Machine dealer you can find something?
Sure hope you can find something to let you play with your machine with confidence.
