The Nolting requires oiling every 8 hours of quilting time. I keep a log so that I know when it's time. It is so simple to oil this machine. On the top of the head are four red dots. One drop of oil on each and that is that.
Well, of course, for me, that is not that. I had to look inside. It just seemed logical. After all I had been using the machine for more than 130 hours and I imagined all manner of lint and dirt building up inside.
I was wrong. It sure was clean inside.
Not to worry. I found some true crud on a Singer 27 I am listing for sale. Gotta love that Tuff Stuff foam cleaner.
