Regulating the Thread Tension DR 580 The bobbin thread tension has been set for a medium grade and need not be adjusted for all ordinary sewing operations.
DR 008 Stitch Length Regulation The stitch length control serves to regulate the stitch length and to limit it in sewing backwards. The numbers on the control indicate the stitch length (the higher the num ber, the longer the stitch). When the control is set on “0” the machine ceases feeding.

Care and Maintenance Longevity and smooth machine performance are dependent on regular and proper cleaning and oiling. Use Pfaff sewing machine oil only, Never lubricate machine with animal or vegetable oils. All moving and rotating parts require regular lubrication.
4 There are two openings in the rim of the stitch width dial, one on the left and the other at the back (see arrows). These openings are the oil holes of the zigzag mechanism. Do not lubricate the bobbin winder. The raceway in the sewing hook is the most important oiling point.
Changing the Light Bulb The built-in 15-watt sewing light illuminates the area of stitching perfectly. To change the light bulb, remove the face cover, push the bulb into its socket, turn left, and pull out. When inserting new light bulb, be sure to slide bulb pins into socket slots.
