|To release the threads and free up my fabric from under the pressure foot, here's what I did that worked;
I lift the foot to it's highest position by turning the handwell (right side) forward.
I use the lever to lift the pressure foot.
I use my right hand and four fingers (if using all three needles) to push the tension buttons above the discs to the right.
With my other hand I open the front cover that has the looper device and I pull on the large round white knob that flicks the looper threading device to the left and releases the thread.
I then carefully pull my fabric away.
I am no expert with this machine as i have only just purchased it, but since this model does NOT have automatic release and I couldn't make heads or tails of the included manual, I tried a few things and this seemed to work for me.
Hope this helps others, I am sure there might be other better ways but this worked for me, and since I am new to this machine, that makes me happy.
Update; I have since read this same method mentioned on the message boards by Sew4Fun, YAY, it works!!
