Once this adjustment is made, it will not require re-adjustment when changing welt lengths. Loosen the socket head cap screws (A) holding the centerknife pivot block (B) and slide it towards the front of the machine to decrease center cut length and touards the rear of the machine to increase center cut length. "Caution": Positioning the pivot block too far forward may result in interfer– ence with the thread trim bracket. It may become necessary to readjust the centerknife to the throat plate if the above adjustment is made. · To adjust: This adjustment is made after setting the finish 'cut position. The center cut should start approximately 3/16" after sew. The Knife UP limit switch fires the solenoid valve which drives the knife up through the material into cutting position.

Sliding switch towards front of the machine increases center cut length and towards the rear of the machine decreases center cut.
