Question

Hi, I have a new Consew 206RB-5. I followed the directions in the manuel how to thread the bobbin on the side of the machine. The only thing is I turn on the machine and nothing happens. Am I supposed to press something I don't understand.I need to know how to thread the bobbin on my Consew. The bobbin is the drop-in ,not insert to the side type. I just can't figure it out. Probably very simple... The bobbin is filled and the machine is threaded properly, but can't figure how to get the boobin thread to catch. I am doing something wrong in threading the bobbin.
