I am in need of a picture with instructions to put the bobbin in place. the bobbin goes in the the front left side and has a larger circular piece that holds it in place by 2 slide bars. there is one black plastic bar on each side. If no one can help I will have to take it to a sewinf machine repair man. I need a picture and instruction to be able to put the bobbin in place. all of these are in the front of the machine
