TABLE OF CONTENTS PERFORMANCE CHECK LIST Whenever sewing difficulties are encountered, review the section in this instruction manual that details the operation you are performing to make sure you are correctly using the machine. If the problem continues, the following check list may help you to improve the operation. If you still have difficulties, contact your nearest authorized service center. With the model PS-2470, you can use the sewing speed controller to adjust the sewing speed. When sewing at the slowest speed, skipped stitches may easily occur depending on the type of thread and fabric used. If this occurs, sew at a faster speed.
