bylinesupplyco Report post Posted May 6, 2015 Hello all! So in the last few months I've gotten the hang of my Pfaff 145. Great machine for what I'm doing. However, I have noticed that the presser foot marks the majority of the leather I'm sewing from too much pressure. I loosened the wing nut on the back of the machine according to the instruction book, however I can see and feel that the foot pressure is still too high. Does anyone know how to adjust this pressure so all of my leather doesn't get marked?! Any help appreciated. Thank you! Quote Share this post Link to post Share on other sites
Constabulary Report post Posted May 7, 2015 Not sure which wing nut you mean on the backside of the machine. The only wing nut I remember is for adjusting the foot lift hight. Can you post a picture of your machine? There are 2 different 145 with different ways of adjusting the foot pressure. One with 1 or 2 blade springs on top and the other has just a knob above the foot spring. Quote Share this post Link to post Share on other sites
bylinesupplyco Report post Posted May 10, 2015 Here are the photos. I adjusted the wing nut in the back as loose as I could get it, and also from info I found on another thread, adjusted the black protrusion that comes from the top of the machine, but still getting marks from the presser foot pressure.

Constabulary Report post Posted May 10, 2015 Okay, you have the variant w/o the blade spring. If you had the blade spring variant and 2 springs were installed you could have taken one off. The "knob" on top of the head is for regulating the pressure. Turn it counterclockwise for reducing the foot pressure. The wing nut is not for foot pressure it is for adjusting the foot hight. Do you have a manual for your machine ? I´m sure it is explained there. Not sure what kind of markings you have. Are you probably using presser feet with toothed bottom? Then I´d either grind down the teeth or buy a new feet set with smooth surface. Quote Share this post Link to post Share on other sites
bylinesupplyco Report post Posted May 11, 2015 Ill try and adjust it some more its just very difficult to get that knob on top to move. Do you know where I could find new presser feet with a smooth bottom that would fit my machine? Quote Share this post Link to post Share on other sites
Constabulary Report post Posted May 11, 2015 Shouldn´t be too difficult to adjust it. Or is it probably gummed up or maybe secured with a set screw (you never know). I´m sure one of the dealer who have banners on top of the page can help you with the feet. My source would probably be College Sewing in the UK but I live on the other side of the pond.

bylinesupplyco Report post Posted May 20, 2015 So I've done everything I can do try and adjust that tension, and yet its still leaving presser foot marks all over my pieces. Im not sure if switching out the feet is really going to do anything, since even if I use presser feet without teeth, its still going to leave an impression. Anyone have any ideas on what I can do?

Constabulary Report post Posted May 23, 2015 try to find a weaker spring or cut some coils from the original spring. Quote Share this post Link to post Share on other sites
