First, there is a right and wrong way to thread the bobbin shuttle
. For my brother, the bobbin goes in so the thread makes a 180 degree turn through the tensioner.
As you put the shuttle in, have the thread in the right side of the little vertical piece. Hold the loose end of the needle thread and cycle the machine 1 stitch., holding the thread tight. It should pull up a loop from the bobbin.. pull it and the needle thread off the back.of the machine and sew away..
Hope this helps... if not p m me... we can talk via cell...
