DR 050 A :It Fundamentals of Machine Operation • Whenever you have to turn the balance wheel, turn it toward you (counter-clockwise as shown by black arrow). Make sure the stop motion knob is tightened before you begin sewing. • Never run a threaded machine unless you have fabric under the sew ing foot. —-H’ • Place both threads back under the sewing foot before you put fabric into the machine. • The machine will feed the material under the sewing foot automatically.
How to Operate Your Sewing Machine Engaging the Sewing Mechani sm .4 Hold balance wheel and turn stop motion knob clockwise (as indicated by black arrow). Disengaging the Sewing Mechani sm Hold balance wheel and turn stop motion knob counter-clock wise (toward you). The sewing mechanism is disengaged for bobbin winding.

Leave about three inches of thread hanging from the bobbin case.
iij Inserting the Bobbin Case Raise take-up lever to its highest point and lift the latch with the thumb and forefinger of your right hand. Turn bobbin case until slot points up (see arrow). Place bobbin case on center stud s of hook. 4 In replacing the bobbin case, it is best to hold the loose end of thread so that it will not get jammed between bobbin case and hook. Release the latch and press against bobbin case until you hear it snap into place.

The threads interlock on the surface of the fabric. Sketch Ii C a u s e: Upper tension too tight or lower tension too loose. A Drawing Up the Bobbin Thread Hold needle thread lightly in your left hand.
DR 580 Regulating the Thread Tension The bobbin thread tension has been set for a medium grade at the factory and need not be adjusted for all ordinary sewing operations. If a special sewing operation should require a looser or tighter tension, turn the small knurled screw on the bobbin case as follows: for looser tension. W\ Turn it left for tighter tension.

‘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. Put one drop of oil into the raceway each day you sew. From time to time, remove the needle plate and clean the machine feed with a soft brush Take a toothpick and remove accumulations of packed lint.

Guide the into place (see page 11). Push bobbin case until you hear it snap Remedy: Adjust tensions as instructed.
6. Machine Works Heavily Cause: Hook raceway lacks oil or is obstructed by pieces of thread. Mechanism clogged by inferior oil. Bobbin winder working while sewing (when a bobbin is not being filled). Remedy: Clean and oil hook raceway. Use only Pfaff sewing machine oil — never salad oil or glycerine. Stop bobbin winder. 7. Motor Idles Cause: Motor disengaging lever raised.

Twin needles are available for needle distances of (3/4), 1.2 1.6 (‘/e”), 1.8, 2.0 millimeters. - (/64”), 2.5 (/32”), 3.0, and 4.0 (/32”) Cording feet are available in three varieties, as follows: Pin tucks are made with cord ing foot No. 847 680 (7 grooves, 3/4 wide each) and a 1.2-mm twin needle. For narrow cording use cord ing foot No. 847 675 (5 groo ves, 1 /u.” wide each; see ill.) and a 1.
Turn sewing foot thumb screw b to the left and take out the sewing foot. Slip on cording foot and tighten screw b securely. it is best to turn out screw b completely if you want to slip on a cording foot with the guide attached. Thread Size Pin tucks and narrow cording are made with a No. 50 embroidery thread, wider cording with sewing silk in the needle and on the bobbin. Set the machine for a medium stitch length (about 4). Upper Threading Place a spool of thread on each of the two spool pins.
0R058 Spacing between Tucks To ensure uniform spa cing between parallel tuck s, place the preceding seam into of the groove s of the foot and use it as a guide. For a larger spacing betw een tucks, use the adju stable guide (see ilL on page 42) which is part of every cording foot. Various Cording Effects Attractive cording effects may be obtained by com bining horizontal, verti cal and diagonal tucks or stitching curved tucks (see ill, below).
DR 059 93100t19 Ornament& Sewing You can make exciting fashion stitch designs by alternating straight and zigzag stitching, varying stitch length, stitch width or needle position by hand. This will be easy after you have had sufficient practice. Some of the designs you can make are illustrated below. V I Interesting two-needle effects can be obtained by using a 1.6 mm twin needle (see page 41) and different color thread. For twin-needle sewing, the stitch width dial should not be turned beyond 1 1/2”.
93100178 Coarse-Thread Embroidery Machine Setting: Stitch width lever A = 0 to 4; needle position lever B = optional; stitch length: small to medium. Buy coarse, four-ply embroidery thread in the desired colors from your Pfaff dealer. Embroidery designs made with this thread are very attractive. They have dimensional quality and closely resemble manual embroidery work. The adjoining designs were made with the zigzag stitch.
