I have fixed it now the bobbin case didn't seem to stay seated during sewing or tangling i should say!. I decided to change the needle and from then on everything worked fine.

Hiya, the threading for this machine is pretty standard so you won't be going wrong there. Have you used a sewing machine before? The tension dial (on the extreme left) should be set at 5. The other dial to your left should be on blue zigzag with orange broken line. The dial on the right should be set at 0 and the bottom one on 2 - 3. I've been looking for a manual for this machine as I inherited this one. It took me ages to suss straight sewing out. Another thought is take it to a repairer and ask for a quote. Good luck.
