7 WINDING THE BOBBIN Disengage the hand wheel (Fig.5) from the stitching mechanism by turning the clutch toward you or counter-clockwise. Place a spool of thread on one of the spool pins, lead thread through the upper rear thread guide (1) and to the right around the bobbin winder tension discs (2). Make one winding around the discs and run end of thread through a hole in the bobbin edge and place bobbin on spindle (3) fitting the notch in bobbin over small pin on spindle.
8 THREADING THE BOBBIN CASE Refer to Figs. 7, 8 and 9 and practise the following procedure. Hold the bobbin case in your left hand. Let about two inches of thread hang free from the bobbin, and insert bobbin into case so that thread will be rotating counter clockwise. Guide the thread end through the slot on the side of the case and under the tension spring until it enters the small notch on the edge of the spring. PLACING BOBBIN CASE IN SHUTTLE Open cover plate in front of the needle. (See 9 Fig. 1).

Replace with straight stitch foot (Fig.13) and tighten screw securely. To change needle plate (10, Fig.
11 SETTING THE STITCH LENGTH The length of the stitch is regulated by the lever (A) shown in F’ig.15. Near 0 is the shortest and 4 the longest. Adjust stitch length stops by turning knurl knob on end of stitch regulator. A F r*rd I ON —a Fig. 15 HI Fig. 16 SEWING IN REVERSE When you wish to sew in reverse to tie the threads at the beginning or the end of a seam, push down lever (A) as far as it will go. The machine will sew in reverse untill lever (A) is returned to the forward stitching position.
12 ADJUSTING THE TENSION Always adjust the upper thread tension with the pre sser foot down, as the tension automatically released when is it is raised. To increase the tension turn dial (A) (Fig. 1?) to the right, or clockwise. To decrease, turn to the left. The higher the number on the dial, the tighter the tension Set numbers to indicating . pointer (B). Before adjusting lower tens ion, be sure the machine is threaded correctly. When necessary to change the bob it is bin tension, turn small scre w (Fig.
13 ADJUSTING PRESSURE AND WEEDIN G OF’ FABRIC General Sewing Usually, for straight sewing, zigzag stitching, and manual embroidery, the press ure bar cap or darning release (A) (Fig. 22) is at its lowe st position and the feed is at its highest level with the drop feed knob (A, Fig. 16) turned to HI position. A Sewing ryhin or Lightweight Fabrics When lighter pressure is required to sew satisfactorily on thin silk or flimsy material, the pressure bar cap should be about half-way down.
14 REMOVING THE WORK Be sure to stop the machine with the thread take up lever and needle bar at the highest position. Now raise tte presser foot and draw the fabric back and to the left, Pig. 23 and 24, and pass the threads over the thread cutter (A). Pull down sharply, holdeing the threads in both hands, so as not to bend the needle. Leave the ends of thread under the presser foot. 1’ Fig. 23 Fig.
15 ZIGZAG STITCHING Be sure zigzag needle plate and presser foot are in place. 1. Moving lever (A. Fig. 25) gradually down and up will produce zigzag stitches of varying widths. To maintain selected widths of zigzag stitches, emplo y locks(C, Fig.25). 2. Lower lock determines the minimum width stitch width, while upper lock controls the maximum. Locks can be set by turning to the left in slightl y and moved to the desired position and tightened. CREATIVE EMBROIDERY-SATIN STITCH The satin stitch (Fig.

18 MAKING BUTTONHOL ES Buttonholes of various widths and lengths can be made easily. correct length button To establish the hole required add 1/8 inch to the desired cutt tacks. To obtain the ing space for bar length of the cutting space, the opening throu passes is measured by gh whic h the button adding the width (A) and thickness (B) of the but ton.(Fig.30). The width of the but tonhole sides are gove rned by the thickness a lower numner for of the material and thin material.

Turn drop feed knob to E position. 4. Set zigzag width lever at 0. Place the button so its left-hand hole comes directly unde r the needle, then gently lower the presser foot. 5. Move zigzag stitch width lever down until the needle comes down exactly over the right -hand hole in the button. 6.
21 If you wish, you may place a rounded toothpick over the button, between the two holes, and sew button to fabric in regular way. Remove the toothpick and wind thread under the button forming A shank to faster. Apply the above method to sew on buttons with four holes, also hooks snaps and etc. If a four hole button is to be sewn, follow the same procedure above as for the two hole button. Now lift presser foot slightly and move fabric to permit the sewing of the remaining two holes. (Fig.35).
22 QUILTING The quilting attachment incl uded with your machine will enable you to sew horizontal lines on padded fabric without the necessity of marking them in advance. To attach the quilter raise the presser foot lever and loosen presser foot screw. Insert forked portion of quilter holder from behind needle and between presser foot screw and presser foot shank. Push holder as far as it will go and tighten presser foot scre w. (Fig.37).
23 NARROW HEMMER With needle at its highest position replace regular presser foot with narrow hemming foot (Fig.39) tightening it securely in place. Set zigzag width lever at 0 for a straight sewn hem or at number 3 for a zigzag sewn hem. Set stitch length control to suit. For a plain narrow hem make a 1/8 inch double fold for about two inches along the edge of fabric. Hold each end of the two inch fold, slip under hemmer.
24 SEWING WITH BRAID Replace regular presser foot with braiding foot (Fig.41). Thread braid through the small hole at front of foot. Set zigzag width and stitch length of the braid is obtained. Draw design YOll wish to sew on fabric with tailor’s chalk, and place material under foot being sure that the braid from the notch in the foot is at the beginning of the design. Start sewing guiding material and braid with hands. Be sure that upper thread overcasts the braid in the notch of the foot. 7ID Fig.
