Bobbin case on brother sewing machine

Well, from the picture I see that your bobbin is a front load as opposed to a top load.. if you tilt the front panel down, you will see where the bobbin and casing goes. Put the bobbin in the casing with the thread pulling from the right hand side of the casing making sure the thread in guided into the small **** on the top edge of the casing.. On the back of the casing the will be a small tab. Pull that away from the casing and enter the casing in to the opening for the bobbin. It should snap into place when you release the little tab.
