Question: I have started to sew badly, 1.-the bobbin thread can be seen at the top and the top one is fully stretched. Apparently it is the tension of the thread above, but I have put the tension wheel on all the numbers and it does not change anything. 2.-Another thing that it also does to me is, the bottom stitch looses and sometimes the thread gets tangled underneath It does not do the two things together, one or the other I can't find the solution in the manual, I follow the instructions in the manual and it doesn't fix anything

Hello, your problem is very easy to repair, it is only the tension of the bobbin, or check that it does not have lint stuck in it.
