korokan Report post Posted August 29, 2014 Was adjusting the presser foot tension on the Pfaff 335 or Mauzzer cylinder sewing machine, Was sewing leather and it is marking on my work so I decided to lessen the tension. I turn the knob on the top silver thumb screw and when I tried to sew ,the other foot on the back just stay down only the other foot move up and down. Called the dealer and told me something must have gotten loose of fall off while I was doing the adjustment. The machine wont sew anymore cause only the other foot on the back wont move up and down. when you do a foot lift manually it goes up. Other than that it keep on staying down. I open the cover to check if anything loose and cant find anything loose or parts . The spring that is the tension presser foot is there . Was the loosening of the tension on the presser foot has to do with it ? This is a new machine about a year and seldom being used. Quote Share this post Link to post Share on other sites
Darren Brosowski Report post Posted August 31, 2014 Sounds like something in the mechanism that drives the outer foot has come lose. Rotate the machine by hand and see if you can detect where one of the rotating parts is not driving its appropriate component. Quote Share this post Link to post Share on other sites
