Pfaff 1245 Foot Problem

[Park Ranger]

Pretty sure my Pfaff 1245 has a problem. The secondary vibrating foot contacts the lower feed dogs and pushes off. Seems like the secondary foot should have a small clearance under it for materials to take up the shock rather than hammering down on the feed dogs. It doesn't matter how high the vibrating foot's adjusted, it still hammers down. Not sure how to adjust this even though I've downloaded a user's manual.

My other machine, a Juki 241 operates smoothly without hammering the feed dogs. Haven't taken the Pfaff to the shop for adjustment yet. Looking for some advise first. Thanks for any technical advise.

#1 you could have the foot presuure to tight.#2 When does the inside foot come down?The needle should come down just slightly before the inside foot comes down on the feed dog.

Thanks for the reply Bob

The adjustable foot pressure spring was removed some where down the line by a prior owner. My local Pfaff dealer says this is common since that spring applies excessive pressure and in often removed. One of the repair steps I looked at in the service manual has to do with timing of the needle bar and the vibrating foot. They seemed to be set according to specs, but I'll check again tomorrow.

Hi George. Bob is right. The inside (center foot), outside foot, and needle, should all touch the plate/feed dog at about the same time. I am not sure what you mean when you say that the feet are "hammering down on the feed dogs", but if they don't come down all the way, the machine will not feed properly. Also, both feet should alternate coming up the same height. If your Juki presser feet are not coming down all the way to the plate/feed dog, then you probably will have a problem sewing very light materials. Steve

Thanks Steve,

Well, that sounds like my answer, the center foot should touch the feed dog. I was thinking because this model Pfaff is considered a pretty heavy duty machine, that the center foot shouldn't be making heavy contact with the feed dogs. My Techsew GA5-1 is a harness and bridle machine that has clearance under the foot that is taken up by the material being pulled through by the feed dogs. The Pfaff is certainly a different machine from the Techsew and a different generation of machine from the Juki. The Juki might be of lighter overall internal construction, but seems to feed anything, light or heavy with excellent stitching. It also runs absolutely smooth without the pounding or heavy contact by the center foot of the Pfaff. I've seen a few threads where people were complaining about their machines pounding from being out of time and that's what caused my concern about the Pfaff. Thanks again for the advice and your response.
