Mhicks Report post Posted September 15, 2023 (edited) I admittedly messed up by making some adjustments to the machine before downloading a maintenance manual. My presser foot wasn't going down far enough to hold 2 layers of canvas and I saw the 2 screws in the clamp for the presser foot bar so I loosened them, made my adjustment and continued on sewing for awhile (at least 6 or 7 bobbins worth). I ended up adjusting at the same place again back toward its original position but at some point things just went bad. My presser foot is now raising when the needle bar is just past the top of its stroke and is only raising ~.2mm so the material doesn't move when sewing. I have a manual but don't see anything in relation to the presser foot timing with the needle bar. First question would be is the GK-373 the same as the subclass 373 listed in the technical data to set the Bottom Feed Stroke and Alternating Top Feed Stroke? Second is if I go through and adjust the Lower Feed, Feed Dog, Lifting Distance, and Upper feed should that get things back in sync or is there something else to look at? And yes I now know the correct place to adjust the height of the feet. Edited September 15, 2023 by Mhicks Quote Share this post Link to post Share on other sites
