I do not know how to rewind the bobbin. I bought the sewing machine at a garage sale. There was no manual or instructions

You can get a manual from several online sites, including Singer.

Thank You- i've been looking at your question and the 626 I was just given on thursday, feb. 2nd. I call the button on the left, The Red Dot if we have the same year. Is the right position all the way back with the dot as high as it will go? You can get the bobbin started and slip it back in and then use the motor to wind? WOW.... i like mechanics but I know zip about threading the machine or the bobbin! Once in though, I really enjoy it!

I just found out my accident. There is a small round button like on the left side of the bobbin that has to be moved to get the bobbin out, push it forward. Wrap thread from the spool already threaded. Use the foot Peddle as usual...that should do it. Be sure to push the button to its normal place when starting to sew.
