Pal, I have
http://www.singerco.com/support/instruction-manuals bookmarked as first place to look for Singer and White manuals. I downloaded the manual for your machine from there.
I have downloaded some Janome manuals for other badged machines as well. I don't remember the model, but I was surprised initially to see that Janome had a "Singer" manual. Evidently they were the manufactures. I also found a Janome manual for a machine I have badged Necchi Omega. I have a Kenmore and Janome machine that are just 'dressed' differently and even found a service manual for each of them. Maybe if you found a similar Janome machine you may be able to find a service manual for one or the other.
