Question about Singer 7422
I can't sew more than 5 inches without this thing going crazy. The thread gets all loose and loopy on the back of the fabric, the thread around the bobbin bunches up and I have to remove it all and start over again. IOr all the lights just light up and it starts beeping and I have to shut it off and turn it back on to get it to start sewing again, for what good that does. I have checked to make sure it is threaded correctly several times, checked to make sure the bobbin is in correctly. Adjusted the tension from one end to the other and this machine will just not sew. Anyone have any suggestions, I am at a lost.
Pull the thread through the tension assembly and
test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle.
If it passes this test you need to remove the bobbin case and check for burrs or rough spots. If you find any ,use an emery stick to remove them and then buff the area with fine steel wool.Put the bobbin case back in ,check your bobbin(change it ) and try again by turning the handwheel slowly and watching to see where thr thread is snagging
