I seem to remember that you can download a copy of the machine's owners manaul from Pfaff's website. I 'lost' my manual about 2 month's ago (a month after I bought the machine) so I went to the trusty internet for help threading. Found the manual two days later, that's what I get for cleaning the sewing room. Off to buy a desk at Ikea so it can have it's own permanent home.
