My pfaff synchromatic 1215 won't sew

SOURCE: My pfaff synchromatic 1209 machine--the

You machine has a screw that fits the end of the shaft and the head pof the screw has broken. You can buy a new screw from a sewing machine dealer but if the whole assembly has come off you may need to take it to a dealer to have it reassembled properly. There is a spring inside which is very difficult to install.

You don't have the thread in the take up lever or it is not in the tension. Rethread it , 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. Make sure your needle is fully inserted and turned the correct way. set your tension to 5 and try it.

Hi there, I know this is completely off track from your question but I've been searching high and low for an instruction manual for the pfaff 9063, yours is the only thread I've found that mentions the machine, i wonder if all this time you know of anywhere that I could get one from ? Thanks a mil and I hope you managed to sort out your problem...

Take the foot off the machine
Remove the needle plate
Remove the feed dogs
rotate by hand until the needle is at the lowest position
continue rotating until the needle rises 2 mm
the hook assembly should be passing exactly by the scarf of the needle
if not loosen the two screws that secure the the hook assembly and rotate the hook assembly by hand until it is exactly at the scarf of the needle and the distance between the hook and the scarf is .1 mm (almost touching the needle)
tightened the two screws, replace the feed dogs and foot and it should sew perfectly
