SEWING BASICA SEWING BASICS Sewing Basic sewing operations are described below. Before operating the sewing machine, read the following precautions CAUTION While the machine is in operation, pay special attention to the needle location. In addition, keep your hands away from all moving parts such as the needle and hand wheel, otherwise injuries may occur. Do not pull or push the fabric too hard while sewing, otherwise injuries may occur or the needle may break. Never use bent needles.
SEWING BASICA stitch can be selected from the following types available. For details on the various stitches, refer to "Stitch Setting Chart". a. Utility stitches You can select from 67 utility stitches, including straight line stitching, overcasting, button holes and basic decorative stitches. If this is selected, the utility stitch selection appears right after the power is turned on. b. My Custom Stitch You can design original stitches.
SEWING BASICA Selecting utility stitches 1.Follow steps a to c in "Selecting stitching" . 2.Select a stitch. Memo The utility stitch selection screen appears when you turn on the machine. Example: When 11 is selected: Positioning the fabric Be sure that the fabric pieces are sewn in the correct order and that the right and wrong sides of the fabric are aligned correctly. 1. Turn on the machine. 2. Press (Needle position button) once or twice to raise the needle. 3.
SEWING BASICA 5. Lower the presser foot lever. 1 Presser foot lever The fabric is now positioned to be sewn. Starting to sew Once you are ready to start sewing, you can start the sewing machine.

However, you can change any of the settings by pressing in the screen, then follow the procedure described in this section. Note Settings for some stitches cannot be changed.
SEWING BASICA Memo means the setting cannot be adjusted. If the straight stitch (left needle position or triple stretch stitch) was selected, changing the stitch width changes the needle position. Increasing the width moves the needle to the right; reducing the width moves the needle to the left. For details, refer to "Changing the needle position". Press to return the setting to its default. If the foot controller is connected, the sewing speed controller can be used to adjust the zigzag width.
SEWING BASICA Adjusting the thread tension You may need to change the thread tension, depending on the fabric and thread being used. ■ Correct thread tension The upper thread and the bobbin thread should cross near the center of the fabric. Only the upper thread should be visible from the right side of the fabric, and only the bobbin thread should be visible from the wrong side of the fabric.
SEWING BASICA ■ Upper thread is too loose If the upper thread is visible from the wrong side of the fabric, the upper thread is too loose.

Otherwise, injuries may occur if (Start/stop button) is accidentally pressed and the machine starts sewing.
UTILITY STITCHES Appliqué stitching A Cut out the appliqué, leaving a seam allowance of between 3 and 5 mm (1/8 and 3/16inch) B Place a pattern made of thick paper or stabilizer on the back of the appliqué, and thenfold over the seam allowance using an iron. C Turn the fabric over, and then baste or fuse it onto the fabric that it will be attached to. D Attach zigzag foot "L". • For details on replacing the presser foot, refer to "Replacing the presser foot". E Select a stitch.
UTILITY STITCHES When sewing around corners, stop the machine with the needle in the fabric just outside of the appliqué, raise the presser foot levers, and then turn the fabric as needed to change the sewing direction.
UTILITY STITCHES Patchwork (crazy quilt) stitching A Fold the edge of the top piece of fabric and place it over the lower piece. B Sew the two pieces of fabric together so the pattern spans over both pieces. Piecing Sewing together two pieces of fabric is called "piecing".
