I believe you're trying to find out how to thread a bobbin. Most sewing machines have a way to hook the thread from the spool around a starting point at the top of the machine, then start it around the bobbin & put on a smaller pin near the thread spool. Then you disengage the needle, usually by pushing a button on the needle feeder wheel, or by turning the two parts of it in the opposite directions. Then step on the power pedal as if you're sewing, & it will wind. As for threading your entire machine, your owners manual would have the specifics. It varies from model to model. If you don't have your owners manual, try the site www.singerco.com, & you should be able to find something there.
