Engaging the Sewing Mechanism Hold balance wheel and turn stop mo tion knob clockwise (as indicated by black arrow). Disengaging the Sewing Mechanism Hold balance wheel and turn stop mo tion knob counter-clockwise (toward you). The sewing mechanism engaged for bobbin winding. is dis Foot Drive Push sewlight plug into wall outlet. Mount driving belt. To switch on sewlight, push button on face cover. Important Always turn balance wheel toward youi For sewing, pull the spool pins out partway.
OFt 861 Electrical Information Power Drive 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. Foot Control Place the foot control under the ca binet within easy reach of your foot. Rest the right foot on the control pedal and press. The harder you press, the faster the machine will run. (Foot-driven machines have only a sewlight cord).
Removing the Bobbin Case Raise needle to its highest point. Lift front end of bed slide and pull. Lift latch k with the thumb ol your left hand arid pull out bobbin case with bobbin. When you release the latch, the empty bobbin drops out.
\ Winding the Bobbin Disengage the sewing mechanism and raise the spool pins to the vertical po sition. 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 rightharid 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.
Inserting a Full Bobbin Hold bobbin so that the thread end falls from the top down toward you and insert bobbin into bobbin case. Hold the bobbin firmly in the bobbin case and pull the thread into the case slot.
Pull the thread under the tension spring until it emerges from the opening at its end. Leave about 3” of thread hanging from the bobbin case. Hold the case by its open latch so that the bobbin cannot fall out.
Inserting the flobbin Case Raise needle to its highest point and lilt latch k (see ilL at bottom of page 6) 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. In re placing 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 latch k and press against bob bin case until you hear it snap into place.
I The Needle Pfaff 71 machines use System 130 R needles. Genuine Plaff needles of this system are available from every Pfaff dealer. The needle size should be cho sen from the Needle and Thread Chart on page 12. Changing the Needle Bring needle bar to Its highest point and lower sewing foot. Loosen needle set screw a half a turn and pull old needle out of needle clamp. Push new needle up as far as it will go. Make sure that flat side of shank faces toward the back and long groove toward you.
50 to 70 40 to 50 Determined by weight of fabric 40 to 50 Medium Fabrics such as lightweight woolens, madras, muslin, brocades, heavy silks, rayon, and gabardine. Heavy Fabrics such as coating, denim, corduroy, slipcover fabrics, bed tickings, lightweight canvas. Synthetics, Rayon, Acetate including nylon, orion, dacron, plastics, etc. twist C&D 8&c twist A&B twist 70 to 80 Lightweight Fabrics such as dress silks and cottons, sheer woolens, shirting, draperies.
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.). 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 draw the thread into the left eyelet.
Drawing Up the Bobbin Thread Hold needle thread lightly in your left hand. Turn balance wheel toward you until the needle moves down and up again. Lightly pull needle thread to draw bobbin thread up through the needle hole. Place both threads back under the sewing foot.
Correct Tension Regulation The tensions are properly balanced if both threads interlock in the center of the material. When stitching sheer fa brics, set both tensions a little lighter to prevent puckering. Both tensions properly balanced Upper tension too tight or lower tension too loose Upper tension too loose or lower tension too tight.
Regulating the Upper Tension Turn tension knob right to increase tension on heavier materials. Turn it left to ease tension on lighter fabrics. The numbers on the tension dial indi cate different degrees of tension. Regulating the Lower Tension The bobbin tension rarely needs adjust ing, except for special sewing jobs. Ad justment is made by a small knurled screw on the bobbin case. Turn it right for tighter tension or left for looser tension.
Stitch Length Regulation The stitch length control serves to re gulate the stitch length and to limit it in sewing backwards. The numbers on the control indicate the stitch length (the higher the number. the longer the stitch). When the con trol is set on O’, the machine ceases Feeding; maximum stitch length is 6 to the inch (4 mm). To regulate the stitch length, turn the control until the desir ed number is fully visible at the top of the slot (see arrow).
Fundamentals of Machine Operation • 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. • Always bring the take-up lever to its highest position before you begin rind after you have completed a seam. • The machine will feed the material under the sewing foot automatically. All you have to do is guide the work. Never try to hasten feeding by pushing or pulling the fabric With presser foot No.
_‘%_ Z.._, R 8228 —— .., ., Inserting Patches Large holes can be patched quickly. Trim away ragged edges around the hole, cutting a square opening exactly on the fabric threads. Cut the patch slightly larger and sew it down (inner seam). Cut into corners, fold down raw edges and stitch along folded edges (outer seam).
Zipper Insertion Attach edge stitcher No. 93-847 600-00 without guide. Pm or baste closed zipper on wrong side of fabric. Position of zipper depends on whether or not you want the edge of the fabric to overlap the zipper, Turn fabric to right side. Flun a straight seam close to left edge of zipper, stitch across end and up the other side in one continuous operation Use right edge of foot as a guide.
Hemming Hemmer foot No. 93-847 551-00 is in dispensable if you want to sew a uni form hem. Clip off the corner of the fabric to facilitate insertion into the hemmer foot. Feed fabric so that the raw edge is in line with the left edge of the hemmer foot opening. Avoid ugly ends by slowing down feed ing. To do this, press the fabric against the needle plate on the left side of the foot before you come to the end of the hem.
Quilting sews parallel rows of used with the quilting gauge Edge stitcher No. 93-647 600-00 gauge finger along the the guide of the fabric. Always stitching over the entire surface covers can be quilted cosies, slippers, seat pads and preceding seam.
Dropping the Machine Feed Remove the bed cover and press the drop feed ever down slantwise, then to the rear and up (as indicated by the white arrow). The lever wilt 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 with Darning Hoops machine (See page 23 for preparing your for darning.) hoops, cut Clamp fabric into darning holes out small arid mediumsized stitch First grain. following the fabric the with hole the across forth back and Then machine running at high speed. and sew turn the fabric at right angles work ing preced over forth back and threads with short stitches. This anchors hole.
Darning with Sewing Foot No. 93-839 950-00 Triangular tears, small rips or thin spots are best darned by making close stitches back and forth over the area to be darned. To do this, attach the sew ing foot and set the needle plate in the normal position. While darning, guide the material with your left hand and operate the reverse feed control in rhythm with your right hand.

Various Cording Effects Attractive cording effects may be ob tained by combining horizontal, verti cal and diagonal tucks or stitching curved tucks (see adjoining ill), If you want to turn a corner, leave needle in fabric (up to needle eye only), lift foot, turn fabric, lower foot, and continue sewing. To stitch an acute angle, turn fabric halfway, let needle make one stitch, turn fabric all the way, and re sume stitching.
Ornamental Sewing Two-Needle Decorative Effects Two-needle effects can be obtained by using presser foot No, 93-838 954-00 with needle slot and a NE 1.6 twin needle. The stitch length can be set as desired. Particularly nice effects can be obtained by using varicolored thread. Presser toot No.93-838954-00 Straight-Stitch Hemstitching Stitch Length: Medium. with needle slot Attach presser foot No. 93-838 954-00, and insert twin hemstitching needle, System 130 Zwi-Ho, as instructed on page 11.
Procedure Fold fabric to mark seamline or trace seamline on fabric. Sew first row. Guide fabric so that wing needle stitches along trccad in. At the end of U seam, turn fabric half a turn and sew second row. Guide fabric in such a way that wing needle penetrates the needle holes it has made and enlarged previously. Imitation hemstitching thus requires at east two operations, If desired addi tional straight or curved ornamental seams may be stitched parallel to the first one.
Your Pfaff can be used for many additional sewing operations. See your Pfaf[ dealer who will be glad to offer you various sewIng feet and attachments which will con siderably enlarge the range of applications of your machine. Such additional applications include felling, granite stitching, embroidering mono grams, sewing on wool, and straight-stitch embroidery with four-ply thread. Interest ing effects can also be obtained with the multi-stitch ruffler and the bias binder.
