up and down
Every sewing machine is a little different, so be sure to read your manual. You want to make sure that the machine is threaded correctly from the top (through the mechanisms and through the needle) and the bottom (called the bobbin.) Most sewing machines have a foot pedal, which you step on as you position the fabric to pass under the needle.
Prior to the invention of the sewing machine, sewing was done by hand with needle and thread. This method was very time consuming and consequently people only owned a few pieces of clothing, not the closets-full that we do nowadays.
An electric sewing machine does it's work by using electricity to move the needle up and down, and rotate the bobbin. The mechanical parts of a manual sewing machine, had to be set in motion by turning a handle, or pedal. An electric sewing machine has an electric motor attached to these rotating parts, by belt or gearing and operated by a foot switch. This makes it less tiring on the arms or feet, you can keep sewing faster and longer.
The screw that tightens to hold the needle in place, and loosens when you want to change the needle.
The hand wheel on a sewing machine is primarily used to raise the needle in order to feed or remove the work (seam, zipper, button or whatever you are sewing) into or out of the machine. It is also used to advance the work slowly to reach a certain point manually, where you might again resume sewing.
