Note ●If the sewing machine is to be operated using the foot controller, connect the foot controller before turning on the machine. ●When the foot controller is plugged in, the start/stop button cannot be used to start sewing (only for models equipped with the start/stop button). iWhen the bobbin begins spinning slowly, take your foot off the foot controller or press (start/stop button) (for models equipped with the start/stop button). jCut the thread, slide the bobbin winder shaft to the left, and then remove the bobbin from the shaft. kSlide the sewing speed controller back to its original position (for models equipped with the sewing speed controller). Memo ●When the sewing machine is started or the handwheel is turned after winding the thread around the bobbin, the machine will make a clicking sound; this is not a malfunction. ●The needle bar does not move when you slide the bobbin winding shaft to the right. ●Be sure to cut the thread as described. If the bobbin is wound without cutting the thread using the cutter built into the slit in the bobbin winder seat, the thread may become tangled in the bobbin or the needle may bend or break when the bobbin thread starts to run out. CAUTION ●Not winding the bobbin properly may cause the thread tension to loosen, and may break the needle. aWound evenly bWound poorly CAUTION 12

For more details on quick-set bobbin, see page 21. Memo ●The direction for feeding the bobbin thread is indicated by marks on the needle plate cover. Be sure to thread the machine as indicated. aRaise the needle to its highest position by turning the handwheel toward you (counterclockwise) or press (needle position button) (for models equipped with the needle position button), and raise the presser foot lever. bTurn off the sewing machine. cSlide the button and open the cover. aCover bSlide button d Put the bobbin in so the thread comes out in the direction shown by the arrow. ●Winding the bobbin improperly may cause the thread tension to loosen, breaking the needle and resulting in injury. aWound evenly bWound poorly ●The bobbin was designed specifically for this sewing machine. If bobbins from other models are used, the machine will not operate correctly. Use only the enclosed bobbin or bobbins of the same type (part code: SA156, SFB: XA5539-151). ●Make sure you turn the power off while threading the machine. If you accidentally step on the foot controller and the machine starts to sew, you could be injured. CAUTION 12 Actual size This model Other models 11.5 mm (7/16 inch) CAUTION ●Make sure you set the bobbin so the thread unrolls in the right direction. If the thread unrolls in the wrong direction, it may cause the thread tension to be incorrect or break the needle. 12 CAUTION

If the thread is not correctly inserted through the tension-adjusting spring of the bobbin case, it may cause incorrect thread tension (page 41). aTension-adjusting spring f Replace the bobbin cover. Put the left tab in place (see arrow a), and then press lightly on the right side (see arrow b) until the cover clicks into place. Replace the cover so that the end of the thread comes out from the left side of the cover (as shown by the line in the diagram). ■For models equipped with the quick-set bobbin Memo ●The direction for feeding the bobbin thread is indicated by marks on the needle plate cover.

22 KNOWING YOUR SEWING MACHINE ——————————————————————————————————————————————————————————————————————————————————— eWhile lightly holding down the bobbin with your right hand as shown, guide the thread through the slit ( a and b). At this time, check that the bobbin easily rotates counterclockwise. Then, pull the thread toward you to cut it with the cutter ( c). aSlit bCutter (Cut the thread with the cutter.) Note ●If the thread is not correctly inserted through the tension-adjusting spring of the bobbin case, it may cause incorrect thread tension (page 41). aTension-adjusting spring fReplace the bobbin cover. Put the left tab in place (see arrow a), and then press lightly on the right side (see arrow b) until the cover clicks into place. Memo ●You can begin sewing immediately without drawing up the bobbin thread. If you want to draw up the bobbin thread before you start to sew, follow to the procedure in “Drawing up the lower thread” (page 28). 1

For details on the needle threader, see page 26. aSpool pin bMark on the handwheel a Turn on the sewing machine. bRaise the presser foot using the presser foot lever. aPresser foot leverc Raise the needle by turning the handwheel toward you (counterclockwise) so that the mark on the wheel points up, or press (needle position button) (for models equipped with the needle position button) once or twice to raise the needle. If the needle is not correctly raised, the sewing machine can not be threaded. Be sure to turn the handwheel so that the mark on the wheel points up before threading the sewing machine. ●When threading the upper thread, carefully follow the instructions. If the upper threading is not correct, the thread may become tangled or the needle may bend or break. ●Never use a thread weight of 20 or lower. ●Use the needle and the thread in the correct combination. For details on the correct combination of needles and threads, refer to “Needle types and their uses” (page 29). CAUTION ●If the presser foot is not raised, the sewing machine cannot be threaded correctly. CAUTION aMarkbNeedle position button or

XThe spool pin swings up. eRemove the spool cap. aSpool pin bSpool capf Fully insert the spool for the upper thread onto the spool pin. Slide the spool onto the pin so that the spool is horizontal and the thread unwinds to the front at the bottom. gSlide the spool cap onto the spool pin. With the slightly rounded side of the spool cap positioned toward the left, slide the spool cap onto the spool pin as far as possible to the right so that the spool is moved to the right end of the spool pin. ●Do not grab the bar to raise the spool pin, otherwise, the spool pin may bend or break. ●Be sure to raise the spool pin before use. If the spool of thread is in the wrong place, or is set incorrectly, the thread may tangle on the spool pin and cause the needle to break. CAUTION CAUTION ●If the spool or the spool cap is not positioned correctly, the thread may become tangled around the spool pin or the needle may break. ●Three spool cap sizes are available, allowing you to choose a spool cap that best fits the size of spool being used. If the spool cap is too small for the spool being used, the thread may catch on the slit in the spool or the needle may break. CAUTION

Make sure you raise the presser foot lever and the thread take-up lever before you feed the upper thread. ●If you incorrectly feed the thread you may cause sewing problems. ■Using the needle threader (for models equipped with the needle threader) aFollow steps a through m of the procedure in “Upper threading” to thread the machine to the needle bar thread guide. bLower the presser foot lever. cWhile lowering the needle threader lever, hook the thread onto the guide. aNeedle holder bNeedle threader lever cGuide ●Make sure you turn the power off while threading the machine without using the needle threader (for models equipped with the needle threader). If you accidentally step on the foot controller and the machine starts to sew, you could be injured. 1 CAUTION ●The needle threader can be used with a 75/11 through 100/16 home sewing machine needle. However, the needle threader cannot be used with a 65/9 home sewing machine needle. When using special thread such as transparent nylon thread or metallic thread, the needle threader cannot be used. ●Thread with a thickness of 130/120 or thicker cannot be used with the needle threader. ●The needle threader cannot be used with the wing needle or the twin needle. ●If the needle threader cannot be used, refer to “Upper threading” (page 23).
