SOURCE: Machine is jamming

You need to remove the bobbin from the "race" by following the instructions in the manual. Give it a good clean and remove any bits of fluff and thread. Remove the upper thread also andmake sure that the tension wheel is clear of any broken threads and is on the correct setting. It may have been threaded wrong. The hand wheel not turning sounds like the bobbin area is jammed also.

Hello,
Here are a couple of things to try.

* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you
sew.

* When you start to sew a seam, grasp the upper and bobbin thread tails. Hold them back
and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.

I hope this helps.

the tension on the bobbin case needs to be adjusted to needle size and type of fabric the medium fabrics usually use a size 11, light fabrics need a size 9 and heavy like ( corduroy denim or upholstery fabric needs a 14 or 16 Heavy fabrics need a little less tension on the top side so it will feed properly just play with it until it looks good on a scrap of the same fabric

unscrew the black plate that holds in the bobbin case and move it over to the left just a little bit, but make sure there is still clearance between the lower right corner of the case and the plate. The case should be able to wiggle a little, but not so loose it can pop out..
