Singer tension really loose
Can anyone help? I have a Singer 403 and it sews beautifully when set, but the tension knob is very loose and when I am sewing the vibration of the machine moves the dial so that the dial moves to 1 and I end up with birds nests on bottom. Is there anyway to tighten this?

The 401 info will do for this.

I like to print them out and scribble on them you can make extra
401a repair manual - you have to scroll down 125 pages more or less to get to the 401

Since it has been coming off - it probably isn't put on right - you will need to read the instructions very carefully - you can't simply undo and fix this one. I wonder if the set screw on the side of the machine is loose or missing? I do know the directions are pretty good and helped me fix more than one that came with missing parts.

The 403 is my machine of choice... Once you get it straightened out you will love it. Some times your owners manual will have info how to do your tension. If not, there is a repair manual on line and it is free. Here are some links.
