Adjusting the Alternate Bobbin Case (with No Color on the Screw) When using the embroidery bobbin thread provided, please be sure to choose the green marked bobbin case when performing utility stitch sewing and embroidery functions. When in the embroidery function mode, the alternate bobbin case (with no color on the screw) should be selected when substitute embroidery bobbin threads (other than what is accompanied with your machine) are being used. The alternate bobbin case (with no color on the screw) can be easily adjusted when bobbin tension changes are required to accommodate different bobbin threads. Refer to "Embroidering Attractive Finishes" on page 134. MAKING EMBROIDERY ADJUSTMENTS ■ Bobbin Thread Is Too Tight Upper thread on the right side of fabric seems to be lifting/ looping and bobbin thread is not seen on the wrong side of fabric. 1 Right side 2 Wrong side If this occurs, turn the slotted screw (-) counterclockwise, being careful not to over-loosen the screw, approximately 30-45 degrees to decrease bobbin tension. To adjust the bobbin tension for embroidery function, using the alternate bobbin case (with no color on the screw), turn the slotted screw (-) with a (small) screwdriver. ba 1 Do not turn a phillips screw (+). 2 Adjust with a screwdriver (small). ■ Correct Tension Upper thread slightly appears on the wrong side of fabric. 1 Right side 2 Wrong side CAUTION • When adjusting the alternate bobbin case, be sure to remove the bobbin from the alternate bobbin case. • DO NOT adjust the position of the phillips (+) screw on the alternate bobbin case as this may result in damage to the bobbin case, rendering it unusable. 5 • If the slotted screw (-) is difficult to turn, do not use force. Turning the screw too much or providing force in either (rotational) direction may cause damage to the bobbin case. Should damage occur, the bobbin case may not maintain proper tension. Advanced Embroidery ■ Bobbin Thread Is Too Loose Bobbin thread appears slightly on the right side of fabric. 1 Right side 2 Wrong side If this occurs, turn the slotted screw (-) clockwise, being careful not to over-tighten the screw, approximately 30-45 degrees to increase bobbin tension. 145
