Inserting the bobbin 1 2 1. Remove the bobbin cover by sliding it towards you. 2. Place the bobbin in the bobbin case with the logo facing up and the thread unreeling from the left of the bobbin. The bobbin will then rotate counter-clockwise when you pull out the thread. 3. Place your Ànger on the bobbin to keep it from turning as you pull the thread Àrmly to the right and then to the left into the tension spring 3 4 (A) until it "clicks" into place. 4. Continue threading around (B) and to the right B of the thread cutter (C). Replace the cover. Pull the thread to the left to cut. Note: The bobbin cover can be used as a magnifying glass. A C Preparations IDT (integrated dual feed) D For sewing any fabric precisely PFAFF® expression™ sewing machine provides the ideal solution: the integrated dual feed, IDT system. As on industrial machines, the IDT feeds the fabric from the top and bottom at the same time. The material is fed precisely. On light fabrics such as silk or rayon the dual feed prevents puckering of the seam. The even feeding action also ensures perfect matching of checked and striped fabrics. The IDT keeps all layers of quilt projects aligned to prevent shifting of the top layers. Engaging the IDT Important: For all work with the IDT, use presser feet with the center back cut-out (D). Raise the presser foot. Press the IDT down until it engages. Disengaging the IDT Raise the presser foot. Hold the IDT with two Àngers at the ribbed ankle. Pull the IDT down, then pull it away from you to release the IDT slowly upward. 2:6
