Hi All leather workers I bought a Pfaff 545 a few years back missing a few parts. I found parts online and got it working again however it seems that the front tension is not correctly set up. I also have an issue with the clutch slipping under heavy loads and resetting is a pain in the XXX. I am hoping that there is an easier way to set the bottom tension, the clutch and the top tension. Is there a manual? Id love some feedback
