3. ThreadIng the Needle As shown in photo 2, pass the thread from spool 1 through the three slotted holes of thread guide 2, around and between the tension discs 3, through check spring 4, beneath guide 5, through eyelet 6, right-left through take-up 7, through eyelets 8 and 9, needle bar eyelet 10, and then left-right through needle eye 11. Note: [...]

4. Winding the Bobbin All PEAFF 28 machines are equipped with a table winder which hos proved very useful in all sewing shops. As shown in photo 3, place spool 1 on pin 2, and the empty bobbin on spindle 6. Pass the thread from spool 1 through the hole 3, between tenson discs 4, over pin 5, and through the slot in the face of the bobbin. By press n[...]

5. Changing the Bobbin and Threading the Bobbin Case Raise the shuttle race cop by slightly pushing it up with thumb and index finger of your left hand so that it can be slipped over the head of screw a (see photo 4), then let it hong by the hinge screw. Turn the balance wheel until the beak shuttle is in is extreme right-hand position. The b ak sh[...]

3. Lay both threads back under the presser foot. Basic Role: Stop the machine or commence sewing only with the take.up in its highest position. This precaution will keep the thread from slipping out of the needle eye and will prevent jamming of the thread in the shuttle roce. In this case it is not necessary to hold the needle and bobbin threads wh[...]

The bobbin thread tension is regulated by means oF the small screw driver. Turning tension screw d (see photo 8) clockwise , will increase the tension; turning it coueter-clockwise -< will decrease the tension. Since most of the stitching work done on the PFAFF 28 coIls not only for perfect but also for strong and durable seams, the thread tensi[...]

In fig. 12, the needle thread tension may be too loose or the bobbin thread tension too tight. The operator will have to decide in each individual case whether or not either tension requires adjustment, particularly so the thread forms small krots or loops on the upDer or underside of thc material. Fig. 11 Note: The neede thread tension can only be[...]

If the needles are too thick for the material to be sewn, ugly needle marks will show in the material. With long, thin needles, vibration of the needle can hardly be avoided. Therefore, two needle systems comprising needles of different lengths are used with PFAFF 28 machines, depending on the type of work. For machines intended far fine stitching [...]

1O Inserting the Needle In any case, the needle is to be pushed up in the needle bar as far as it will go and to be fastened securely. Flat-shank needles, System 805, ore to be inserted with the flat side of the shank facing the needle bar. However, inserting round-shank needles, System 190 and 690, should present no problem if the following basic [...]

12. The Knee Lever Presser Foot Lifter With the exception of sub-class 28-15, all PFAFF 28 machines are provid ed with a knee lifter which permits to raise and lower the roller presser or presser foot by knee control and allows the operator to rnaniouiate the work with both hands when performing intricate sewing operations. The knee lever pad can e[...]

The extra arge beak shuttle which is used in canjunction with longer needles is of the same type as the standard-size beak shuttle, the only difference being ts larger size to accomodate a bobbin of a greater capa city. 14. Tilting the Machine Over Compared with the obsolete PFAFF 23 and 25 Cylinder Bed Sewing Machines, the PFAF 28 features a consi[...]

As a rule, all bearings and parts n movable contact are to be oiled. After the machine has been tilted over (as instructed in poragroph 1 4), the parts inside the vertical part of the arm are eosily occesstble (see photo 16). The machine will repay thorough cleaning and proper oiling with light running and perfect stitching. All fluff that hos accu[...]

Packed dust or fluff should be carefully removed with a pointed pece of wood. Scissors and screw drivers ore unsuitable for this purpose. The lacquer finish of the machine does not require special maintenance. It is sufficient to rub off the machine now and then with same kerosene and to polish it with a soft cloth. Only in very rare machine exclus[...]

The electric motor calls for practically no maintenance. After a longer period of use, check if there is sufficient grease in the grease bushings. If tilling up is necessary, use only the special motor grease whch we supply in handy tubes. The complete treadle assembly is left on the machine when it is power driven. This means that, in the case of [...]
