oiling a Singer 6233
Hello. I'm new to this forum. I bought a new Singer 6233 machine in the 80s in New York City. I used it steadily till about 2000. I gradually purchased additional machines and used the 6233 less and less. I never oiled it but it was always reliable. About two years ago, it started skipping stitches. I brought it to a qualified Singer repair person. He said it would cost me $150 for him to replace a computer system inside the machine. I told him that I would just pick up the machine. From then I have used it for quick zig zags. But today I used it for some straight stitches and sure enough it skipped stitches again. Examining it I saw there were holes for adding oil in several accessible places. So I got out the manual and was surprised to see that, just as mentioned above, there was no instruction for oiling the machine. So I came downstairs and searched for answers on my computer. Low and behold I found this forum. I'm going to go up and oil those holes and see what happens. Why not? I will let you know.
