Bobbin jumps (followed manual that said the thread was to come off the spool on the left side). When I wind thread onto the bobbin without interference, no matter what I try, I noticed that 90% of the time it is NOT tightly wound. When I use my fingers to force it to wind tighter then the bobbin does not jump as much when I sew at it's lowest speed. But when it jumps, then no stiches are made.
ALSO the manual does NOT say how to adjust the bobbin, and it is WAY too loose. Please help, thanks in advance.
