DR 050 Fundamentals of Machine Operation • Whenever you have to turn the balance wheel, turn it toward you (coun ter- clockwise as shown by black arrow). • Make sure stop motion knob on the balance wheel is tightened before you begin sewing. • Never run a threaded machine unless you have fabric under the sewing foot. • 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.
DR 506 Operation of Your Sewing Machine I Engaging the Sewing Mechanism Hold balance wheel and turn stop motion knob clockwise. Disengaging the Sewing Mechanism Hold balance wheel and turn stop motion knob counter-clockwise (toward you). The sewing mechanism is then disengaged for bobbin winding. Electrical Information IL Power Drive and Sewlight Push plug 1 into receptacle 2 on back of machine, and plug 3 at other end of cord into the wall outlet. Cord 4 leads to the foot control.
DR 558 Motor Disengaging Mechanism Powerdriven machines feature a lever underneath the balance wheel which serves to swing the motor to its operative position. To do this, flick the lever down. After you have completed sewing, flick the lever to its top position in order to return the motor to the inoperative position. With the motor swung out of engagement, all machines set up on treadle stands can be driven by foot power.
DR 851 Straight Stitching For straight-stitch sewing set: Dial A Lever B = = 0 Center • Control G regulates the stitch length. For detailed instructions please refer to page 18. To backtack the end of a seam, simply depress the finger-tip control.
DR 851 Zigzag Sewing If you want to switch from straight (A on O”) to zigzag stitching, turn dial A to desired stitch width (indicated by numbers 1 to 4). Lever B changes the position of the needle in the needle plate slot. Thus the stitching can be moved from the center to the left or right of the slot, as desired. The position of lever B (left, center, right) indicates the position of the needle in the needle plate slot.
Removing the Bobbin Case The needle has to clear the needle-plate. Lift front end of bed slide and pull. Lift latch k with the thumb of your left hand and pull out bobbin case with bobbin. When you release the latch, the bobbin drops out.
1 DR 859 Winding the Bobbin Disengage the sewing mechanism and raise the spool pins to the vertical position. Place a spool of thread on one of the spooi pins and a bobbin on the bobbin winder spindle, making sure that the key at its base enters the slot in the bobbin. Pass the thread through the righthand thread guide, down and around the thread retainer stud, and up to the bobbin. Wind a few turns of thread on the bobbin in clockwise direction. Push the bobbin to the right and start the machine.

Important Facts about Needles On Pfaff 72 sewing machines, System 130 R, flat-shank needles are used for all ordinary sewing and embroidery work. The last column in the chart on page 12 gives you the needle size required for the material in hand Genuine Pfaff needles, System 130 Fl, are available from every Pfaff dealer. Bent or blunt needles should not be used. Changing the Needle Bring needle bar to its highest point and lower sewing foot.
Upper Threading Raise the presser bar lifter and swing the spool pins up to the vertical position. Place spool 1 on one of the spool pins and lead the thread behind both scrolls of thread retainer 2 (see ill. at top of p. 15). Seize the thread on the right and left of the thread retainer and pull it toward you until it snaps into the eyelets. It suffices to drew the thread into the left eyelet. Pull the thread between any two of tension discs 3 (see ill, at bottom of p.

Correct Tension Regu’ation Balanced tensions are essential far sewing. If your tensicn is correct, you will have perfect seams as sketched below (Ill). Sketch I fabric. Caus e : — The threads interlock on the underside of the Upper tension too loose or lower tension too tight. Sketch II —The threads interlock on the surface of the fabric. Cause Upper tension too tight or lower tension too loose. DR 046 A Drawing Up the Bobbin Thread I Hold needle thread lightly in your left hand.
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. If a special sewing operation should require a looser or tighter tension, turn the small knurled screw on the bobbin case with the tip of your thumb as follows: Turn it left Turn it right W’\ for looser tension. for tighter tension.
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. The maximum stitch length is six stitches to the inch. To regulate the stitch length, turn the control until the number indicating the desired stitch length is opposite the mark on the left edge of the slot.
DR 866 it T Changing the Sewing Foot Lift both needle and presser bar to their highest positions and turn sewing foot thumb screw b to the left. Tilt the foot sideways and pull it down. Ii Reverse procedure to slip on new foot and tighten screw b securely.
DR 855 Dropping the Machine Feed Remove the bed cover and press the drop feed lever down slantwise, then to the rear and up (as indicated by the white arrow). The lever will be retained in this position and the fabric will cease feeding. The machine feed is dropped for darning, hoop embroidery and button sewing. To raise the machine feed, press the lever down and let it return to its original position. Darning and Embroidery Foot Remove the sewing foot. Attach darning foot No. 93-102 826-91 from the rear.
DR 853 All-Purpose Sewing Foot (with Clear-View Shoe) All-purpose sewing foot No. 93-100 179-00 is attached as instructed on page 19. The transparency of its shoe facilitates all sewing operation where it is important to watch the needle penetrate the fabric. Special application possibilities are discussed in the second part of this book under the heading Using Sewing Feet and Attachments.
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. Begin under the bedplate. If you have a portable machine, tilt it back, loosen the large thumb screw on the underside cf the machine base, and remove the base. In replacing the machine base, tighten thumb screw lightly.
DR 886 4 There are two openings in the rim of the stitch width dial, one on the left and the other at the oil back (see arrows). These openings are the holes of the zigzag mechanism. DR A 864 Do not lubricate the bobbin winder. important oiling point. Put The raceway in the sewing hook is the most you sew (see picture at top one drop of oil into the raceway each day right). and clean the machine feed From time to time, remove the needle plate accumulations of packed with a soft brush.
DR024 Changing the Light Bulb The built-in 15-watt sewing light illuminates the area of stitchin perfect g ly. 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. Press bulb in and turn right. V Removing the Face Cover To change the light bulb or oil the parts at the needle-bar end, remove the face cover by pulling it upwards.
Trouble Shooting 1. Machine Skips Stitches Cause: Remedy: Needle incorrectly inserted. Push needle up as far as it will go and be sure that the long groove faces toward you, and flat side of shank away from you. Wrong needle. Choose the correct needle from chart on page 12. (For ordinary sewing, use System 130 R needles.) Needle bent, Insert new needle. Machine threaded improperly. Check and correct threading as instructed on pages 14 and 15. Needle too fine or too thick for the thread.
3. Needle Breaks Cause Remedy: Bent needle strikes point of sewing hook. Needle too thin or thread too heavy. Replace needle at once to prevent further damage. Use correct needle and thread sizes. Fabric pulls needle so it bends and strikes needle plate. Don’t force the feeding motion. Guide the material lightly. Bobbin case inserted incorrectly. Push bobbin case until you hear it snap into place. 4. Faulty Stitch Formation Cause: Remedy: Improper tension. Adjust tensions as instructed.
6. Machine Works Heavily Cause: Remedy: Hook raceway lacks oil or is obstructed by pieces of thread. Clean and oil hook raceway. Mechanism clogged by inferior oil. Bobbin winder working while sewing. Use only Pfaff sewing machine oil Stop bobbin winder. — never salad oil or glycerine. 7. Motor idles Cause: Remedy: Motor disengaging lever raised. Flick lever down (see page 5). Thread Jamming The Pfaff rotary hook will not normally jam, even if the machine should be handled improperly.
