Need Instructions for Singer sewing machine

Hello, Annelien -

Unless your manually operated sewing machine has switches to realign your sewing machine needle to make zig zag stitching, as is demonstrated in this YouTube video (starting at around 6:30 minutes in the video):

you cannot. Note: The machine in the video is a Necchi brand sewing machine.

Without knowing the model number of your manually operated Singer sewing machine, I cannot try to find operating instructions for it to determine if your machine has zig zag stitching potential.

Best wishes.

try a new needle

make sure the top thread has not come off the thread take up lever

there could be something wrong with the cam that does the zig zag stitch, if the problem continues you may need to have the machine checked

try here...
1966 Singer Zig Zag sewing machine model 628

or here...
Singer sewing machine Model 628 40 Redmond OR

You didn't give the model name for the machine; however, if it's a Pixie or Pixie Plus, you can download the user's manual that shows you how to thread it and wind a bobbin from the Singer Sewing Machine site. The number listed above your question is not a legitimate model number; it might be a serial number.

From the pattern selector (the bigger dial), select the zig-zag stitch. Then, using the stitch length dial (the smaller dial), adjust the stitch length. The closer your stitch length is to "0", the more dense will your zig-zag stitch be.

By turning the bottom dial on the righthand side of the machine, you can change type of stitch. For zig zag, you need to set it to B (seen on the front of the machine). You can adjust the width of the zig zag using the same dial.
