Pfaff 230/332 Automatic

PFAFF domestic sewing machines normally use System 130 R needles with a flat shank. System 130 B round-shank needles are used for cording and multi-needle decorative sewing. Make sure you use only genuine PFAFF needles!

To correctly regulate the tension on the threads, begin by setting the bobbin thread tension at a medium grade. Then turn the tension knob of the upper tension until a tightly set stitch is obtained. To check whether the threads are locked in the center of the material, set the machine for a wide zigzag stitch and sew on a piece of medium-heavy fabric. If the tensions are correctly set, the threads should lock in the fabric exactly at the zigs and zags of the seam, and the seam should look alike on both sides of the fabric.

Causes for skipped stitches include incorrect needle insertion, incorrect needle choice, a bent needle, improper threading, and a needle that is too thin or too thick for the thread being used. Remedy: Push needle up as far as it will go and make sure the long groove faces toward you. Insert a new needle. Check and correct threading as instructed in the instruction book. Select the correct needle from the Needle and Thread Chart in the instruction book.
