What do you mean rock frame? That link is broken do u have another link?

So here's another question my needles keep breaking as if the needle is hitting the feed plate. Is it the needle that I need to adjust or is it possible that the bobbin hook needs to be adjusted.? I know that the needle needs to be adjusted because it's not grabbing or meeting up with the hook to grab the thread on time. Does anybody know those adjustments I need to make?

So hello everybody I am a total newbie to this whole entire forum I've been selling and been using this machine for about a year and a half now I got it from a friend of my mother's who has since passed but used to do car upholstery with it. So recently I just picked up some small jobs doing zipper repair on Bimini top covers and other small jobs mainly to do with canvas. Yesterday I went to go use my machine and when I went to go sew through the canvas to put the new zipper on the machine would so fine for a second and then break the needle,, as if it were hitting the plate and not in the center of the hole. I was trying to find a service manual for the 545 and the only thing I keep bumping into is the 1245 so my question here at this point is is that the same manual for the 545 that I have? P
