How do I change the bobbin on my sewing machine?

Why does my sewing machine not pick up the bobbin thread?

First, make sure the bobbin-winding spindle (located on top of your machine) has been pushed back to the left for sewing. If it is not in the correct position, the needle will not go down and pick-up your bobbin thread. … Make sure the presser foot is up when seating the thread through the upper tension.
