The machines feature a lever (10) underneath the balance wheel which serves toswing the motor to Its operative position.To engage the motor, flick this lever down.After you have completed sewing, flick thislever to its top position.

5

To remove the bobbin case, turn the balancewheel until the needle is at the top of itsstroke.

On the Piaft 76, remove bed cover (13), asillustrated. Lift latch k on the bobbin caseand pull out the bobbin case with the bobbin.The bobbin cannot fall out as long as youhold the case by its open latch. When yourelease the latch, the empty bobbin dropsout.

On the Pfaff 77, the bobbin case is removedjust like on the Pfaff 76. To get at the bobbincase, however, you must first open free armcover (14) by swinging it toward the left.

Hold the lull bobbin so that the thread unwinds toward you and place it in the bobbincase.

Pull the thread into slot (2) and under spring(3). As you pull the thread, the bobbin shouldrotate clockwise (4). Leave about threeinches of thread hanging from the bobbincase.

8

To insert the bobbin case into the machine,rotate the balance wheel until the needleis at its highest point. Lift the latch andplace the bobbin case on center stud s (seeill.), making sure its slot (white arrow) pointsup. Release the latch and press against thebobbin case until you hear it snap intoplace.

The sewing foot is raised and lowered byoperating the presser bar lifter on the backof the machine (see ill.).A = Presser bar lifter upB = Presser bar lifter down12

To draw up the bobbin thread, hold theneedle thread and lower the sewing foot.Turn the balance wheel toward you a fullturn. Pull the needle thread to draw up thebobbin thread.Place both threads back under the sewingfoot after it has been raised again.

Fundamentals of Machine Operation

For ordinary sewing, needle position lever(19) should be in its center position.

Make sure the take-up lever is at its highestpoint before you begin and after you havecompleted a seam (2).

Always rotate balance wheel (8) toward you(see arrow). As you do this, check to makesure the stop motion knob is tightenedfirmly.

Begin by sewing a straight-stitch seam. Tothis end, push stitch width control (18) tothe right as far as it will go.

The stitch length is regulated by turningstitch length control (11). The number indicating the stitch length chosen should beopposite the dot on the left-hand side of theslot.For ordinary sewing operations, set the stitchlength control on 2.Place the material under the sewing footand lower the presser bar lifter.Place the foot control within easy reach ofyour foot and press down the pedal. Theharder you press, the faster the machine willrun.

To sew in reverse or backtack the end of aseam, simply depress fingertip control (12).

The stitch width is regulated by pushingstitch width control (18) toward the left, asmay be desired.Various zigzag sewing operations are discussed on page 26 and the following pages.

Balanced tensions are essential for sewing.Both tensions are correctly balanced if theneedle and bobbin threads interlock in thecenter of the material.

The bobbin thread tension is regulated byturning the small knurled screw on the bobbin case.Turn this screw right (with your thumb nail)for a tighter tension, or left for a looser tension.If the same size threads are used in theneedle and on the bobbin, there is no needto adjust the bobbin thread tension.This tension is set correctly if a slight resistance has to be overcome when pullingthe thread.

Numbers 0 to 10 indicate different degreesof tension on the upper tension dial. Thehigher the number, the tighter the tension.For ordinary sewing operations, the uppertension should be set at about 5.

The accessory box which belongs to yourmachine contains several sewing feet forspecial sewing operations. To change thesewing foot, bring the needle to its highestpoint and raise the foot. Turn out screw 16until the sewing foot can be removed, tilting it sideways (see ill.). The new foot isattached in the reverse order.

To change the needle, bring the needle barto its highest point and tower the sewingfoot. Loosen needle set screw 22 and pullthe old needle out of the needle clamp.Insert the needle and push it up as far as itwill go, making sure that the flat side of itsshank faces toward the back. Tighten screw22 securely.Use System 130 R needles for ordinaryfabrics Consult the Needle and ThreadChart on the front inside cover.

17

DarningTo prepare your machine for darning, proceed as follows:

Replace the ordinary sewing foot by darning foot No. 91-102826-91, attaching it fromthe rear so that spring clip c rests on needleset screw (22). Tighten sewing foot thumbscrew (16). Lower the presser bar lifter.

Now drop the machine feed. On the Pfaff 76,this is done by removing bed cover (13) andpressing the drop feed lever down slant-wise, as indicated by the white arrow.

To raise the machine feed, press this leverdown and let it return to its original position.

On the Pfafl 77, the machine feed is droppedby simply turning the thumb screw on theunderside of the free arm. To raise the machine feed again, turn this screw in the opposite direction.

Darning sheer and soft materials is greatlyfacilitated by placing them in darning hoops.Draw up the bobbin thread and hold boththreads lightly with your left hand while thefirst stitches are being made. Trim thethreads and start stitching back and forthacross the hole in sewing direction. Makesure the threads are anchored in the unwornarea around the hole.Turn the fabric at right angles and sew backand forth over the preceding work with shortstitches.Select the darning hoops in a size matchingthe darning job to be performed.If the needle thread should break, the uppertension is too tight.

19

Zipper InsertionAttach zipper foot without quilting gauge.Stitch length: 1.5 to 2.Central needle position.

84

Baste closed zipper on the fabric, then openit. Stitch close to the left edge of the zipperfor about 1 inch, guiding the right edge ofthe foot along the zipper teeth (1). Leavethe needle in the material, raise the zipperfoot and close the zipper (2).Continue stitching until you reach the endof the zipper. Then stitch across this end (3)and up to the other side.The finished zipper closure is shown inFig. 4.

20

Flat Felled Seams

Attach flat feller No. 93-847561-00.Stitch length: 1.5 to 2.

Flat felled seams are used to durably jointwo pieces of fabric and are usuallystraight-stitched.

First Seam: Lay pieces together with theright sides facing and the bottom pieceprotruding about 1/8 inch. Make sure thefabric enters the flat feller evenly and thebottom fabric is folded over the edge of thetop piece (see ill.), but the top piece is notfolded.Open the two pieces.

Second Seam: Lightly tension the fabric bypressing it against the needle plate in frontof the foot. Insert the seam ridge into thefelling foot and stitch down (see ill, at right).

HemmingStitch length: 1.5 to 2

847 551

Fold the beginning of the fabric edge twice,making a hem about 1/s inch wide and severalinches long. Place the material under thehemmer foot and lower the same. Make 3 to4 straight stitches to secure the folded edgein place.Draw the fabric into the hemmer by pullingboth threads backwards, as shown in thedrawing.Feed the fabric edge into the hemmer footscroll with your right hand (see ill.), makingsure that the scroll is well filled with fabricat all times and the fabric does not slip sideways under the right half of the foot.To produce an elastic hem on soft fabrics,

use zigzag stitches. Set the stitch width, asinstructed on p. 25.

22

Cording

Use ordinary sewing foot No. 93-838 954-00,and insert a twin needle (which can be obtained from your Pfaff dealer).Stitch length: 1.5 to 2.Cording is made with two needle threads.When threading the needles, make sure tolead each thread between a separate pairof tension discs (see ill.).To render your cording more prominent, insert a filler cord. Select the twin needlegauge and the size of the filler cord to suitthe type of material used. The thicker thefabric the wider the needle gauge.Lace the filler cord through hole g, as illustrated. Hold both needle threads lightly androtate the balance wheel to draw up thebobbin thread.

The smallest distance between cordingseams made with the ordinary sewing footis approx. 1/4 inch. For narrower cording,use one of the cording feet listed below.To make different size cording, the following twin needles and cording feet can besupplied at extra cost:Twin needles for needle distances of 1.2(/e4), 1.6 (Vie), 18, 2.0 (5/e4), 2.5 (/32), 3.0and 4.0 (/32) mm.Cording foot No. 93-847 671-00, with 3grooves is used for heavy materials,cording foot No. 93-847 675-00 with 5grooves for medium-heavy fabrics, andcording foot No. 93-847 680-00 with 7grooves for lightweight materials.

Ptaff 77Pfaff 76

23

Use a thread which is not too heavy andmatches the material being hemstitched(preferably a No. 50 embroidery thread).Insert a System 130 Twin hemstitch needle.Make sure the needle and bobbin threadsare the same size. The threading procedureis the same as for cording work. Slightly increase the needle thread tension.The hemstitching effect is produced by theleft wing needle penetrating the fabric. Turnthe fabric by half a turn and sew the secondseam, guiding the material so that the wingneedle enters the needle holes it has madein the fabric previously.You can produce a nice hemstitching effectalong the hemmed edge of the fabric byguiding the material so that the right needlestitches into the fabric close to the hem.

25

Overcasting Edges with Zigzag Stitches Attach ordinary sewing foot.

Stitch length: 2.

838 954uTo overcast the edges of light and medium-weight fabrics, set the machine for its maximum stitch width.

Soft and flimsy fabrics are best overcastwith a zigzag stitch of medium width.

Make sure the needle takes one stitch intothe fabric and the other over its edge. Thiswill cover the fabric edge securely.

26

Inserting Patches

Set the stitch length control on 1 and thestitch width control in the middle of its slotand stitch along the edge of the patch.Set the stitch length control on O5 andthe stitch width control at the extreme leftof its slot and sew over first seam.At the corners, stop the machine with theneedle down in the material on the right ofits throw. Then turn the fabric so that thecorners are stitched twice (see ill.). Trimaway the excess material on the wrong side.Elastic materials are patched in the samemanner.

Stitch width: medium.

838 954

Larger holes can be patched quickly. Trimaway the ragged edges around the hole,cutting exactly along the fabric weave.Cut a patch about /2 inch larger than thehole and place it under the hole, matchingits grain to that of the fabric.

27

Inserting LaceStitch length: 1

838 954u

Place the lace on the material and stitch itdown with straight stitches on both sides (1).Cut the fabric open under the lace insertion(2) and iron it on both sides of the lace.Sew over the edges of the lace with shortzigzag stitches of medium width (3). Trimthe fabric edges away on the wrong side (4).

Sewing Buttonholes

Attach buttonhole foot No. 847616 to themachine and set the slide on the buttonholegauge to the buttonhole length desired.The number indicating the buttonhole lengthshould be in line with the right edge of theslide. The buttonhole is the right length whenthe beginning of the first seam reaches thered end of the slide indicator (see arrow).Flick the needle to its left position and putthe stitch width control in notch R 1 (see ill).When using No. 50 embroidery thread, setthe stitch length control so that both dotsare opposite each other (see ill.). For heavierthreads, slightly increase the stitch length.

To obtain more prominent buttonholes,place a filler cord of medium size in theleft groove of the sewing foot.

All-purpose sewing foot No. 91-100 179-00may also be used for this operation.

Sew the first seam over the filler cord.When the buttonhole is the right length,leave the needle in the fabric on the rightof its throw. Lift the sewing foot, turn thefabric around clockwise by half a turn, placethe filler cord aroL.!nd the needle and pullit forward, placing it in the left groove ofthe foo. Lower the foot and take one stitchby hand.Move stitch width control (18) to the secondnotch, R 2, make 4 or 6 bartack stitches,slightly holding the material to reduce thelength of bar.Push stitch width control (18) back to thefirst notch R 1 and sew the second buttonhole seam, stopping about /io inch from theend of the first seam.

Slightly pull the filler cord and trim it closeto the bar (5).

Push stitch width control (18) to the secondnotch R 2 and sew the second tack, slightlyholding the material to reduce the length ofbar. Flick the stitch width control all the wayto the right and make 3 to 4 fastening stitches.Open the buttonhole with your seam ripperwhich is included in the accessory box.

To change the light bulb, remove the facecover by pulling it in the direction indicatedby the arrow.

Push the light bulb into its socket, turn leftand pull out. Insert the new bulb so that itspins slide into the socket slots. Press thebulb in and turn right.

As you replace the face cover, slip tip d intoslot c, then push against the face cover untilit snaps into place.

36

Machine CareLongevity and smooth machine performanceare dependent on regular cleaning and proper oiling. Since your Pfaff sewing machinehas been made from high-grade materials,there are only a few oiling points left.

The raceway in the sewing hook is the mostimportant oiling point. From time to time,put a drop of oil into the hook raceway (seeill, at left and center). Do not oil the bobbinwinder.

The other oiling points in the machine areillustrated below. (Remove the face cover asinstructed on p. 36).

37

r From time to time, clean the parts in themachine arm and in the vicinity of the sew- ing hook with a soft brush.To this end, remove the needle, the sewingfoot and the bobbin case with the bobbin.

On Plaff 77 machines, loosen the set screw,lift the front of the free arm cover and pullthe cover out lengthwise of the arm (1 &2).Pfaff 76 machines are tilted back. On portable machines, loosen the screw on the bottom of the machine base and tilt the machineback cautiously (3).

Trouble ShootingWhen operated properly, your sewing machine will hardly develop any trouble.

Please remember to restore the normal setting after you have completed your sewingjob (buttonhole sewing or darning, for instance) by switching the machine back tostraight stitching, flicking the needle position lever to its central position, raising themachine feed and setting the stitch lengthcontrol on 2.

If trouble should occur, check the foIIowing

The needle must not be damaged andmust be inserted correctly.

Selectthe correct needle and thread fromthe Needle and Thread Chart.

Check whether the needle has beenthreaded correctly.

Use only high-grade machine thread orsewing silk.

Check to see that the bobbin case hasbeen inserted correctly.

Both tensions must be balanced correctly.

. Dont force the feeding motion, merelyguide the material lightly.

Clean and oil the machine as instructed.

Make sure there are no pieces of threadwedged between the tension discs. Toremove them, pull a narrow fabric stripbetween the tension discs.

The Pfaff rotary hook will not normallyjam, even if the machine should behandled improperly.

If thread should happen to jam in thehook raceway, It is sufficient to put adrop of oil into the raceway, jerk thebalance wheel back and then rock itback and forth, without applying force.
