Hold the loose end of the needle thread in your left hand, and turn the fs wheel toward you by hand until the needle moves down through the needle plate and tip again to its highest position. Pull the needle thread gently. and the bobbin thread i1l come tip with it through the hole in the needle plate. Then place both ends of the thread back between the toes of the presser foot. N 0 T E : If the bobbin thread does not rise, check to see if there is at least 3 or 4 inches of bobbin thread hanging loosely from the bobbin case. 2. Pull the two threads at least 5 inches behind the presser foot. Place material under presser toot, and lower the foot with the presser bar lifter. Regulate the stitch to the desired size and sew. TO REMOVE MATERIAL, raise the needle to its highest position and raise the foot with the presser bar lifter. then pull the fabric back and to the left. Cut the thread with the thread cutter behind presser bar, leaving a few inches of thread behind the presser foot. 11. ADJUSTING UPPER THREAD TENSION The correct stitch can usually be obtained by varying the upper thread tension . NOTE TENSION ADJUSTMENT SHOULD BE MADE WITh THE PRESSER FOOT DOWN. To increase the tension, turn the tension dial clockwise (Fig. 20). To decrea se the tension, turn the tension dial counter clockwise (Fig. 20). When the tension is properly adjusted, the upper and lower threads will cross in the center of the material (Fig. 21-A). When the upper thread tension is too tight, or the bobbin tension is too loose. the lower thread will lay flat along the top of the material (Fig. 21-B). When the upper thread tension is too loose or the bobbin tension too tight. the upper thread will lay flat along the bottom of the material (Fig. 21-C). The tension should be adjusted little by little until the desired tension is obtain ed. Fig. 20 Fig. 21 12. ADJUSTING BOBBIN THREAD TENSION 1. The bobbin thread tension on your machine is correctly adjusted before leaving the factory. Therefore, it is seldom necessary to alter the bobbin thread tension. Should it become necessary to do so, the adjusting screw of the tension spring on the outside of the bobbin case can be tightened or loosened to increase or decrease the tension of the bobbin thread. 2. To increase the bobbin thread tension, turn the adjusting screw clockwise. To decrease tension of the bobbin thread, turn the adjusting screw counter clockwise. Fig. 22 13.

For sewing very light fabrics, press ‘DOWN” button half way down so that the center line of the “UP” button appears on the plate. 3. To lower the fabric feeders below the surface of the needle plate, piess the “DOWN” button all the way down. The fabric feeders are now in the down position, and you will be able to move your material freely in any direction, such as when you desire to embroider or darn. When embroidering and darning, remove the presser foot and use an embroidery hoop. “UP” Position Normal Fabrics :‘ ;:: DOWN UP DOWN UP S S “DOWN” Position Embroidering & Darning DOWN Fig. 23 Fig. 24 14. ADJUSTING PRESSURE OF THE PRESSER FOOT 1. To release the pressure on the material, press down on the curled ring (A). (This will allow the built-in darner (B) to raise, thus releasing the pressure on the material.) 2. To increase the pressure on the material, press down on the built-in darner (B). NOTE The built-in darner will stop at any position you desire. 3. For normal sewing, push built-in darner all the way down. 4. For darning and embroidering, release the built-in darner. Even though the presser foot is removed, make sure the presser CAUTION bar lifter is in the down position. 5. Adjust the built-in darner to the proper position according to the thickness of the material you are using. 9 Fig. 26 Fig. 25 15. REGULATING STITCH LENGTH SEWING FORWARD The length of the shortest stitch and the marking for a the left to shorten pointer. stitch is regulated by the dial, shown in Fig. 27. Near 0 is the 4 is the longest, but the control may be set at any spot between variety of lengths. Turn the dial to the right to lengthen and to the stitch. The number stitch length you choose is indicated by the SEWING BACKWARD When you wish to sew backward to tie the threads at the beginning or end of a seam, press in the button (Fig. 28) as far as it will go. The machine will sew backward as long as the button is held in. When the dial is set on the number “0’ neither forward nor backward CAUTION stitch can be made. This will cause the machine to break the thread. r Fig. 27 Fig. 28 10 16. ZIG ZAG SEWING Fig. 29 REGULATING_WIDTH OF STITCH The zigzag regulating lever (A) controls the width of the stitch. V hen von It1OVC the zigzag regulating lever, you will notice that the zig7ag indicator ( B) moves from “0” to the numbers 1. 2. 3. 4 on the zigzag indicator plate (C). When the zigzag indicator moves the zigzag regulating lever from “0’’ toward the numbers I 2, 3. 4, the width of the stitch will become progrcssireI ider. The larger the number the wider the stitch.

STRETCH S11TCHING 1’ A /1 r •1.— Fit. 32-I This is a helpful stitch developed to ad elasticity and strength when sewing on fabrics such as knits, jerseys. etc. It reinforces the garment particularly in stress or strain areas. It adds triple strength to straight or zigzag stitching. For a triple strength straight stitth • Set stretch control lever “A” at the SS (stretch stitch) position. 2. Set ZigZag width control “B” at “0” position. 3. Set stitch length control “C” at 4 the longest possible stitch. To sew multiple zigzag stitches simply engage the zigzag width lever to the desired width. This zigzag stitch can be used for overcasting, applying elastic waist bands, etc. There are many other uses for these stitches which will become apparent as you use your machine. To return to normal straight or zigzag stitching, move the stretch stitch lever back to the (M) manual position. Important The stretch stitch controls both the forward and reverse stitch length. If the stitch length control “C” is not set at number 4, the machine will be noisy and the material will feed in reverse. 15 you can form the pattern as in Fig. 40 by slowly moving the zigzag regulating 4. then qutckl lever as the machine is running until the zigzag indicator is on regulating move the zigzag release the zigzag regulating lever and again slowly lever tO 3.
