This underneath the the motor, flick have completed position. is operated by a lever (10) balance wheel. To engage this lever down. After you sewing, flick it to its top With the motor swung out of engagement, all machines fitted with a treadle mechanism can be driven by toot power.
To remove the bobbin case, rotate the ba lance wheel until the needle is at the top of its stroke. On the Pfatl 284, remove bed cover (13), as illustrated. Lift latch k on the bobbin case and pull out the bobbin case with the bob bin. The bobbin cannot fall out as tong as you hold the case by its open latch. When you release the latch, the empty bobbin drops out. On the Pfaft 285, the bobbin case is remov ed just like on the Pfaff 284.
For bobbin winding, disengage the sewing mechanism. Hold balance wheel (8) while turning stop motion knob (9) toward you (see ill.). To engage the sewing mechanism after the bobbin has been wound, turn the stop mo lion knob away from you (as indicated by an arrow in the ill.). Pass the thread around the thread retainer stud in the direction indicated by an arrow. Place a bobbin on the bobbin winder spindle, making sure that key A at its base enters slot B in the bobbin (see ill.).
- Hold the lull bobbin so that the thread un winds toward the right and place it in the bobbin case (1). Pull the thread into slot (2) and under spring (3). As you pull the thread, the bobbin should rotate clockwise (4). Leave about three inches of thread hanging from the bobbin case. 8 -._--v.- -—--. - —-.—--. .- ,. .
I Ptaff 285 Ii To Insert the bobbin case into the machine, rotate the balance wheel until the needle is at its highest point. Lift the latch and place the bobbin case on center stud s (see ill.), making sure its slot (white arrow) points up. Release the latch and press against the bobbin case until you hear it snap into place.

The stitch length is regulated by turning the stitch length control. The number indi cating the stitch length chosen should be opposite the notch on the left-hand side of the slot. For ordinary sewing operations, set the stitch Ienght control on “2”. Place the material under the sewing foot and lower the presser bar lifter.
To sew in reverse or backtack tL3 end of a seam, simply depress the fingertip control. The stitch width is regulated by pushing the stitch width control toward the left, as may be desired. Various zigzag sewing operations are dis cussed on page 25 and the following pages.
Balanced tensions are essential for sewing. Both tensions are correctly balanced if the needle and bobbin threads interlock in the center of the material. bottom The bobbin thread tension is regulated by turning the small knurled screw on the bobbin case. Turn this screw right for a tighter tension, or left for a looser tension. to Upper tension too tight or lower tension loose. If the same size threads are used in the needle and on the bobbin, there is no need to adjust the bobbin thread tension.
The accessory box which belongs to your machine contains sev eral sewIng feet for special sewing ope rations. To change the sewing foot, bring the needle to its highes point and raise the foo t t. Turn out screw 16 until the sewing too t can be removed, tilt ing it sideways (see ill.) . The new foot is at tached in the reverse order. For elastic fabrics, use ordinary sewing foot No. 93-838 954-00 ins tead of clear-view foo No. 93-100 179-00.
Attaching the Embroidery and Darning Plate Darning Embroidery and darning plate No. 93-030 125-45 For certain sewing operati ons, the machine feed must be render ed inactive. For this purpose, an embroidery and darning plate is included in the accesso ries of your Pfaff 284 or Pfaff 285. Apply this plate as follows: Bring the needle to its highest point. Remove the sewing foot. Raise the bed cover and pull forward.
/ E Darning sheer an d facilitated by pla soft materials is greatly cing them in hoops. Draw up darning hold both threads the bobbin thread and lightly with your while the first lef stitches are being t hand Trim the threads made. and start stitching forth across the back and hole in sewing direction. Make sure the thr eads are anchore unworn area aro d in the und the hole. Turn the fabric at right angles and sew back and forth over the preceding work with short stitches.
Zipper Insertion Attach zipper foot without quilting gauge (which can be obtained from your Pfaff dealer). Stitch length: 1.5 to 2 Baste closed zipper on the fabric, then open it. Stitch close to the left edge of the zipper for about 1 inch, guiding the right edge of the foot along the zipper teeth (1). Leave the needle in the material, raise the zipper foot and close the zipper (2). Continue stitching until you reach the end of the zipper. Then stitch across this end (3) and up the other side.
Flat Felled Seams Attach felling foot No. 93-847 561-00 Stitch length: 1.5 to 2 Flat felled seams are used to durably join two pieces of fabric and are usually straightstitched. First seam: Lay pieces together with the right sides facing and the bottom piece pro truding about /a inch. Make sure the fabric enters the felling foot evenly and the bot tom fabric is folded over the edge of the top piece (see ill, at left), but the top piece is not folded. Open the two pieces.

Stitch length: 1.5 to 2 Fold the beginning of the fabric edge twice, making a hem about 78 inch wide and seve ral inches long. Place the material under the hemmer foot and lower the same. Make 3 In 4 straight stitches to secure the folded edge in place. Draw the fabric into the hemmer by pulling both threads backwards, as shown in the drawing.
7, Cording Cording is made with two needle threads. When threading the needles, make sure to lead each thread between a separate pair of tension discs (see ill.), Use ordinary sewing foot No. 93-838 954-00, and insert a twin needle (which can be ob tamed from your Pfaff dealer). To render your cording more prominent, insert a filler cord. Select the twin needle gauge and the size of the filler cord to suit the type of material used. Stitch length: 1.
Use a thread which is not too heavy and matches the material being hemstitched (pref erably a No. 50 embroidery thread). Hemstitching Stitch length: 2 to 2.5 Clear-view sewing foot No. 93-100 179-00 Insert a System 130 Zwi-Ho needle. Make sure the needle and bobbin threads are the same size. The threading procedure is the same as for cording work. Slightly in crease the needle thread tension. The hemstitching effect is produced by the left wing needle penetrating the fabric.
Zigzag Stitching The stitch width is regulated by pushing the stitch width control toward the left, as may be desired. Never change the stitch width setting unless the needle is outside the fabric. Overcasting Edges with Zigzag Stitches 838 934 Attach ordinary sewing No. 93-838 954-00 Stitch length: 2 foot I. To overcast the edges of light and mediumweight fabrics, set the machine for its maxi mum stitch width. Soft and flimsy fabrics are best overcast with a zigzag stitch of medium width.
Inserting Patches — 38?3.1 Attach ordinary sewing foot No. 93-838 954-00. u Larger holes can be patched quickly. Trim away the ragged edges around the hole, cutting exactly along the fabric yarns. I Cut a patch about inch larger than the hole and place it under the hole, matchi ng its grain to that of the fabric. Set the stdch length control on “1’ and the stitch width control in the middle of its slot and stitch along the edge of the patch. Set the stitch length control on 0.
Inserting Lace Attach ordinary sewing foot Place the tace on the material and stitch it down with straight stitches made with a stitch length of ‘1.5 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 short zigzag stitches of medium width (4). Trim the fabric edges away on the wrong side.
Changing the Needte F’osition Some special sewing jobs are made with the needle switched to the right or left of the needle plate slot. This is done by mov ing lever (19) to the right and left, respec tively. The needle position lever is indispensable for sewing buttonholes.
Sewing Buttonholes 4 Attach all-purpose sewing foot No. 93-1 00 179-00 Flick the needle to its left position and put the stitch width control in notch R 1 (see Figs. 2 and 3). 2 When using No. 50 embroidery thread, set the stitch length control so that the white dot is opposite the groove (see Fig. 4). CPFAFFD For heavier threads, slightly increase the stitch length. To obtain more prominent buttonholes, place a filler cord of medium size in the left groove of the sewing foot.
Sew the first seam over the filler cord. When the buttonhole is the right length, leave the needle in the fabric on the right of its throw (1). Push stitch width control (18) back to the first notch R 1 and sew the second but tonhole seam, stopping about ‘/i inch from the end of the first seam. Lift the sewing foot, turn the fabric around clockwise by half a turn, place the filler cord around the needle and pull it for ward, placing it in the left groove of the foot (2).
Button Sewing 30 100139 Attach clear-view sewing foot No. 93100 179-00 Right needle position Attach embroidery and darning plate. Place the button under the foot and align so that needle will enter the right hole (see ill). Raise the needle, but retain the foot in its lowered position. Regulate the stitch width until the needle alternately stitches through both holes. Sew on the button. Move the stitch width control toward the right and make two or three tying stitches.
Apptique Work 93 To change cover by pull by an arrow. OOI7 Attach clear-view sewing toot No. 93-100 179-00 1 To make appliqué, proceed as follows: 1 Trace the design on the right side. 2. Set the stitch length control on ‘1 stitch along the outlines. 3. Sew the fabric to be appliquéd to the right side with long stitches (1). 4. Follow the outlines of the design on the wrong side with a narrow zigzag stitch (stitch length control on ‘1”), as shown (2). 5.
To change the light bulb, remove the face cover by pulling it in the direction indicated by an arrow. Push the light bulb into its socket, turn left and pull out. Insert the new bulb so that its pins slide into the socket slots. Press the bulb in and turn right. As you replace the face cover, slip tip d into slot c, then push against the face cover un til it snaps into place.
Machine Care From time to time, clean the parts in the machine arm and in the vicinity of the sew ing hook with a soft brush. To this end, re move the needle, the sewing foot and the bobbin case with the bobbin. On Pfaff 285 machines, loosen the set screw, lift the front of the free arm cover and pull the cover out lengthwise of the arm (1 & 2). Pfaff 284 machines are tilted back. On port able machines, loosen the screw on the bottom of the machine base and tilt the machine back cautiously.
Longevity and smooth machine performance are dependent on regular cleaning and proper oiling. Since your Pfaff sewing ma chine has been made from high-grade ma terials, there are only a few oiling points left. The raceway in the sewing hook is an important oiling point. From time to time, put a drop of oil into the hook raceway (see ill, at left and center). Do not oil the bob bin winder.
Trouble Shooting If trouble should occur, check the following: When operated properly, your sewing machine will hardly develop any trouble. * The needle must not be damaged and must be inserted correctly (p. 17). Please remember to restore the normal setting after you have completed your sewing job (buttonhole sewing or darning, for instance) by switching the machine back to straight stitching, flicking the needle posilion lever to its central position, and setting the stitch length control on “2’.
