I recently bought a used White dsm, model # 1955, series 00490. I bought it as backup to my Brother and also in hopes of fmq. It works fine, actually great, but no manual and I can't seem to find any info online for this particular model. Is anyone familiar w this machine or can you direct me to a website? I can find info on varied models but nothing on this one. I can't seem to find a way to lower the feeddogs but read something about putting a piece of plastic or cardboard covering over them. (?). Any info you have is greatly appreciated. Thanks in advance for your help.
