I read the manual as I sit in front of the machine. Just got done looking at a video with manual in front of my 401. Made copy of a chart of my 401 for trouble shooting, printed larger for my eyes. I have a binder for the 401. Amazing how the videos coincide with the charts. When we put old appliances out to the curb, we throw in the manuals. Many are more resourceful at jigging than we are. And why not, manual isn't going to do us any good.
