Fig. 1 / Fig. 2 ‘4’ Removing the Bobbin Case Turn the balance wheel toward you until the needle bar is at its highest point. Open the bed slide so that you can see the shuttle. Lift latch A (Fig. 1) with thumb and forefinger and take the bobbin case out of the machine. Release the latch so that the bobbin drops out. Disengaging the Sewing Mechanism Hold the balance wheel with your left hand and, with your right hand, turn the stop motion knob toward you (see arrow in Fig. 2).
Fig. S Threading the Bobbin Case Pull about four inches of thread from the bobbin. Take the bobbin case in your left hand and insert the bobbin into the bobbin case, as shown in Fig. 5. Pull the thread into the bobbin case slot (Fig. 6) and draw it to the right, pulling it under the tension spring and into the deliveryeye (Fig. 7). Fig. 6 Fig. 7 Inserting the Bobbin Case Raise the needle bar to its highest point. Lift latch D (Fig. 8) to keep the bobbin from dropping out of its case.
Fig. 10 c \ 9 8 11 5 - I3 VI 10 2 4 _i— Upper Threading Bring take-up lever 7 (Fig. 10) as high as it will go and place a spool of thread on one of the spool pins. Pass the thread through thread guides 1 and 2, down through thread guide 3, clock wise around and between tension discs 4, and into loop 5 of the thread check spring. Pull the thread up so that it will drop into thread guard 6.
Fig. 13 / III / ( Regulating the Thread Tensions — — — Both tensions balonced correctly. Upper tension too tight or lower tension too loose. Upper tension too loose or lower tension too tight. If the tensions ore not bolanced cor rectly, imperfect stitching will result, os illustrated in Fig. 12. II Ill Upper Tension —. For ordinary sewing, the upper tension should be set between 4 ond 6 on the tension dial (Fig. 13).
R— Fig. 15 Fig. 16 12 Lije 4— —T - II1Ii[j Stitch l.ength Regulation and Reverse Sewing Stitch length control R regulates the stitch length. The numbers on the control indicate the stitch length (the higher the number, the longer the stitch), When the control is set on “0”, the ma chine ceases feeding; maximum stitch length is 6 to the inch (4 mm). To regulate the stitch length, turn the control until the desired num ber is opposite the dot on the left-hand side of the slot.
14 Fg. 8 o Removing the Needle Plate Lift both the needle and presser bars to their highest positions. Push the bed slide to the left. Lift the needle plate by its straight edge and tilt it out (Fig. 18). From time to time, clean the machine feed with a soft brush. As you replace the needle plate, make sure its far end slips under the head of the rear screw before you push it down over the guide screws. Changing the Sewing Foot Raise both the presser and needle bars to their highest positions.
Straight and Zigzag Sewing Check to see that the stop motion knob is tightened securely. Straight Sewing The machine sews straight stitches when stitch width lever C (Fig. 17) is set on “0”. Zigzag Sewing The machine sews zigzag stitches when stitch width lever C is set on any number other than “0”. . Button Sewing Raise the needle bar to its highest posi tion and exchange the normal sewing foot for the button sewing foot (Fig. 20).
Fig. 23 18 Sewing Buttonholes with or without filler thread Attach the clear-view buttonhole foot (Fig. 23). Mark the position and length of the buttonhole on the material with tailor’s chalk. Set the stitch width lever on “2” and limit the stitch width, as instructed on page 13. Set the machine for satin stitching (turning the stitch length control usually to 0.2). Flick the needle position lever to left. Place the fabric under the buttonhole foot and sew the first seam from point A to point B (Fig. 24).
Fig. 26 20 Embroidering and Darning Remove the sewing foot and drop the machine feed. Place the material into darning hoops (Fig. 25) and put it under the needle. Lower the presser bar lifter. Hold the darning hoops with both hands (Fig. 26) and move the work back and forth under the needle while the machine runs at high speed. Be sure to keep your fingers out of the path of the needle.
22 Z4// Fig. 29 — — Blindstich Hemming Flick the needle position lever to right. Turn the fobric wrong side up and fold bock its edge about 1/2 inch (Fig. 29 A). Then fold the material to the desired width of hem, os shown in Fig.29B,ond baste, Fold the hem down so that its bottom edge protrudes about /a inch (Fig. 29 C). Set both the stitch length and stitch width controls on “3” and sew the hem, as illustrated in Fig. 29 C, making sure that the needle penetrates the fold on its left just lightly.
Machine Care Oiling All bearings of moving parts at the needle bar end and under the bedplate of the machine should be oiled occa sionally. In addition, there are a num ber of oilholes on the top cover of the machine. From time to time, remove the bobbin case and put a drop of oil into the shuttle race. Use only a high-grade sewing machine oil for this purpose. After oiling, run the machine for about a minute to work the oil into all bear ings. 24 B io Fig.
26 Fig. 31 Changing the Light Bulb Remove the face cover. Push the bulb up into its socket, turn it left and pull it out. When inserting a new bulb (Fig. 31), be sure to slide the bulb pins into the bayonet socket slots. Press the bulb in and turn it right (see arrows in Fig. 31). Trouble Shooting 5. The needle is inserted improperly. 4. The thread used is too heavy for the needle. 3. Something is wrong with the needle. 2. Thread tension tao tight. 1. The needle is not threaded correctly.
The bobbin thread breaks Remedy: 1. The needle is bent. Cause The needle breaks Wind it properly. Cause: T. When the bobbin thread is not wound correctly, it gets entangled. Draw it back under the tension spring. 1. The thread tenson is not properly adjusted. Cause: Looping of stitches 5. The needle is of inferior quality. 4. The material is pulled by the operator. 3. The material is too thick or heavy. 2. The needle is not attached properly. 2.
