I have been reluctant to call in the guard to fix my Singer, and instead got out the manual to see if I was missing something. Yeah, I’m missing the professional repair manual. 🙂
Searching online turned up a handful of refurbished 5160s, but no Inner Sanctum knowledge that would unlock the door to the innards of my machine.
Butterick 4790 is still in pieces, my Halloween costume still needs fitting and hemming, and I still need to suck it up and call a shop. Cry, cry, cry.
There are several Singer groups on Yahoo groups. I'm in one (http://groups.yahoo.com/group/Singer/?v=1&t=search&ch=web&pub=groups&sec=group&slk=1) that has some manuals and you could ask in there for one. Alternately you could ask for help in repairing your problem as well. They have been helpful to me in the past in trying to rewire a 201 and someone even emailed me privately and gave me a pdf of a manual. Hope that helps!
