Hi - We thought we had a problem with our rotary hook and I proceeded to take it out and replace it with a new one that we had. Turns out the problem was not in the rotary hook, but a broken gear elsewhere. My problem though, is in installing and adjusting the rotary hook. The directions in the tech manual are skimpy at best! The diagrams are awful. It took me awhile just to figure out which protruding piece of metal was the hook. I've got it back in, in what I think is the proper location (not even sure of this) and I need to make sure it will work because we have a couple of big orders to get out tomorrow. Does anyone have photos, or a more detailed description on how to make sure the hook is installed correctly and adjusted properly? Thanks Larry All Star Embroidery Duvall, WA
