I am desperately looking for an instruction manual for my Baby Lock Denim Pro Model 1750 but cannot find one anywhere. Can some one please help me ?? Thank you

Raise the presser foot, remove the bobbin case, remove the needle plate. Make certain your correct needle is installed right, with no thread in the needle, rotate the hand wheel until you see the needle at the very bottom of its travel. The hook should be just at the edge of the needle or a fraction from it. As the hook and the needle pass the needle has to start its travel up in order to create a hoop of thread for the hook to catch. If there is not enough travel for a sufficiant hoop to be made the machine may sew but would skip stitches or may not sew at all. If it hits it to late this can cause the hook to split the thread.
