drafthorses Report post Posted May 27, 2022 I have PFAFF 138 it was sewing properly and suddenly now jams up. It will travel to the top but not continue decending on the other side.... I think that the Needle bar is suddenly out of adjustment. It hits the top and will not continue. Will go down and go up on back stroke and stop at the top. Also the tip of the needle only reaches the top of thee Bobbin Any assistance on how to adjust??? thanks Quote Share this post Link to post Share on other sites
Constabulary Report post Posted May 27, 2022 (edited) Needle probably hit a hard spot or the needle plate and the NB moved up. I think you can reach the NB clamp screw from the front side see red circle (pic stolen from the WWW) check the attached file - it may help you with adjustments.
