INTRODUCTION

This Addendum provides additional information not described in the Instruction and Reference Guide. Refer to these instructions after first reading the Instruction and Reference Guide provided with your sewing machine.

USING THE CIRCULAR ATTACHMENT TO SEW PATTERNS IN A CIRCLE

About the Circular Attachment

This device can sew circular patterns that graduate out at 5mm intervals, ranging from 30mm to 130mm in radius* when the center needle position is selected. The device is set to the left of the needle on your sewing machine. Utility and decorative stitches can both be sewn using this device.

* Radius= Distance from center of circle to any point on the circle.

Note

- You cannot use any decorative stitch with side feeding or stitches with a width over 7.0 mm. Before sewing on your project, be sure to sew trial stitches and check the sewing results. If stitches that cannot be used are sewn, the pattern may become misaligned. For a list of stitches that cannot be used, refer to the table “LIST OF STITCHES THAT CANNOT BE USED WITH THE CIRCULAR ATTACHMENT” located on page 17.

CAUTION

- Special care is required for the pivot pin; neglectful treatment may cause injury. Young children should be supervised to ensure that they do not play with the attachment. When attachment is not in use, always keep the pivot pin in the indicator to avoid its loss.

Note

• We recommend that you use the extension table on your sewing machine for smooth fabric control.
- Do not raise the extension table when the circular devise is attached.
- The pivot pin may be released if you hold up the fabric while attached to the circular attachment. When holding up the fabric gently press down on the top of the pivot pin.
- When sewing smaller circles or using fabric with a grain or uneven textures, a perfect circle may not be achieved.
- Some of presser feet such as the side cutter cannot be used with this attachment, always test your accessory feet with the attachment.
- When using this attachment test the sewing speed of your machine for the best results.
- When sewing larger pieces of fabric or garments, make sure that your fabric or garment does not get caught on the machine creating drag or distortion of your design.

Attaching the Circular Attachment

1 Place the circular attachment at left as shown in the figure.

→ The two tabs on the underside of the attachment will drop down into corresponding holes in the needle plate, so that the attachment lays flat on the bed of your machine.

CAUTION

- Do not leave the pivot pin inserted in your fabric and not attached to the circular attachment. To do so may result in accidental injury or machine damage.

Using the Quarter Circle Template

When combining utility or decorative stitches, or repeating an individual stitch, use the included template as a guide.

1 Mark the pivot point (center of your circle) prior to sewing on the fabric (①).
2 Select your desired stitch and the size of a circle using the markings on the attachment, then place the fabric on the attachment.
3 Sew a single stitch or one pattern combination (②).
4 Remove fabric or garment from attachment.
5 With temporary pencil draw two lines from the pivot point, one at the start of your stitch pattern (③) and one at the end of the stitch pattern (④).

①Pivot Point
②Single stitch/Pattern combination
③Start of the stitch
④End of the stitch

6 Place the template on top of your design, lining up the center pivot point and the center marking on the template (①). Then place the 0 degree line on the right side of template (②) at the start of the stitch (③).

①Center on template
②0 degree line
③Start of the stitch
④End of the stitch

7 Check the line at the end of the stitch (④) and note the approximate degrees. With a circle measuring 360 degrees divide the stitch length (your degree/stitch measurement) into 360 and that will give you an approximate count on the stitch repetitions. SAMPLE: Your stitch is 16 degrees long so: 360 divided by 16 equals 22.5 repetitions.

Note

• This is not an exact count due to the number of variables i.e. stitch length, fabric used, thread and the stabilizer. You may be able to adjust the length of the stitch, depending on the stitch used, increasing or decreasing to get a closer match so that your circle closes without overlapping or shortage (①).
• Always stitch a trial version of the design checking the stitch length, width and the direction of sewing, making sure that it is suitable for your project.
  • Additional calculations may be necessary if your pattern overlaps.

Example: Shortage of the Pattern

Using the Included Presser Feet

Using the included presser feet, you can embellish your sewing projects, giving them a professional look with your personal flair.

BRAIDING FOOT

You can use a wide variety of braiding up to 5mm in width, using straight, zigzag and select decorative stitches.

CAUTION

- Do not use this foot when sewing with densely woven braiding that is difficult for the needle to penetrate easily. Doing so could result in needle breakage, damage and/or injury.

1 Loosen the screw on the guide plate sliding the plate to fit the width of the braid.

■CORDING FOOT

You can embellish using 1 to 3 cords of decorative threads or yarn.

1 Slip a cord from the right of the presser foot, into each guide (to use single cord, use the center guide).

2 Place the cords under and to the back of the cording foot.

3 Select a zigzag or decorative stitch and sew in a circular manner gently guiding the cords.

Note

- When sewing with zigzag or decorative stitches, adjust the stitch width, so that it is slightly wider than the width of the braid or cording.

CREATING BOBBIN WORK

About Bobbin Work

Beautiful embroidery work, with a three-dimensional appearance, can be created by winding the bobbin with heavy weight thread or ribbon, which is too thick to be threaded through the machine's needle. The decorative thread or ribbon will stitch out on the underneath side of fabric while sewing with the fabric wrong side facing up.

Required Materials

■Bobbin case and cord guide bobbin cover

①Bobbin case (gray)

There is a notch at the location indicated by the letter "A".

②Cord guide bobbin cover (for bobbin work or attaching cording using single hole).

There are two small v-shaped tabs on the back of the bobbin cover as indicated by the letter "B".

The tabs help hold the bobbin in place so it does not lift up while thick thread is being pulled through.

■Lower thread

We recommend the following types of threads for bobbin work.

No.5 or finer hand embroidery thread or decorative thread

Flexible woven ribbon

Fine embroidery ribbon (silk or silk-like material) (3.5 mm (approx. 1/8 inch) or less, recommended)

* When wide ribbon or heavy weight threads are being used, we recommend test sewing with and without bobbin case tension being applied to see which gives the best stitching results. If wide ribbon such as 3.5mm (approx. 1/8 inch) is to be used, we recommend that bobbin case tension not be applied. Refer to page 11 for more detailed instructions.

Note

• Do not use thread heavier than No.5 hand embroidery thread.
• Some threads may not be appropriate for bobbin work. Be sure to sew trial stitches before sewing on your project.

■Upper thread

Upper thread choices can vary depending on the finished look you would like to achieve. By using sewing machine embroidery thread (polyester), multipurpose polyester thread, or monofilament (transparent nylon) thread the appearance of a single design can be changed many times just by choosing a different upper thread weight and/or color. If you do not wish for the upper thread to be visible, we recommend using monofilament thread or polyester light weight thread (50wt. or above) that is the same color as the lower thread.

Needle

Use a needle appropriate for the upper thread and fabric being used. Refer to "Fabric/Thread/Needle Combinations" (in the chapter "CHANGING THE NEEDLE") in the Instruction and Reference Guide.

■Presser foot

Utility stitches or decorative stitches: Monogramming foot "N"

Free motion sewing: Free motion quilting foot "C", Free motion open toe quilting foot "O" or Free motion echo quilting foot "E"

Fabric

Be sure to sew trial stitches on a piece of scrap fabric, which includes the same threads and fabric as what is being used in your project.

Note

- The sewing results may be affected by the type of fabric used. Before sewing your project, be sure to sew trial stitches on a piece of scrap fabric that is the same as the fabric used in the project.

Upper Threading

1 Install a needle appropriate for the upper thread and fabric to be used.

For details on installing the needle, refer to "CHANGING THE NEEDLE" in the Instruction and Reference Guide.

2 Attach the presser foot.

For details on attaching the presser foot, refer to "CHANGING THE PRESSER FOOT" in the Instruction and Reference Guide.

3 Thread the machine with the upper thread.

For details on threading the machine, refer to "Upper Threading" in the Instruction and Reference Guide.

①Beginning of wound thread

CAUTION

- If thread extends beyond the top of the bobbin too much, the thread may become tangled or the needle may break.

Memo

If inserting thread tail through bobbin hole is difficult bobbin can be wound by holding tail and wrapping thread around inside base. Then carefully trim thread tail so it does not extend from the side of the bobbin.

Install the bobbin wound with thread.

Whether or not tension should be applied to the bobbin thread depends on the type of thread used.

■When tension is applied to the bobbin thread

Insert bobbin into bobbin case so the thread unwinds from the left side. Pass the thread carefully through groove of needle plate cover as shown below.

Positioning the Fabric and Sewing

Note • Reco

• Recommended stitches for bobbin work are open "airy" type stitches.
• Be sure to sew trial stitches using same fabric and threads as project in order to check the sewing results.
• The bobbin thread may become tangled due to the type of pattern and thread that are being used. Since this may cause the needle to break, immediately stop sewing if this occurs. Turn off the machine, and then cut out the tangled thread with scissors. Then, clean the race and bobbin case as described in "Preparing the Bobbin Thread" on page 9.

1 Select a stitch. For this example, press

Memo • For be

- For best results, select a longer stitch length and a wider stitch width. Depending on the selected stitch, it may not be possible to change the stitch length and stitch width.

6.0 mm 4.0 mm - + - + - + 4.0

- Depending on the fabric, bunched stitches may result. We recommend selecting a simple stitch and sewing trial stitches to check the sewing results.

Note

- To ensure threads do not come undone after being tied place a drop of fabric glue on knots.

3 If the desired results could not be achieved, adjust the tension of the bobbin thread and of the upper thread, and then try sewing the stitching again.

For more details, refer to "Adjusting the Thread Tension".

Adjusting the Thread Tension

After sewing trial stitches and checking the sewing results, adjust the thread tensions if necessary. After adjusting the tensions, be sure to sew trial stitches in order to check the sewing results.

■Adjusting the upper thread tension

Refer to "Adjusting the Thread Tension" in the Instruction and Reference Guide. We recommend a setting between 6 and 8 for the upper thread tension.

■Adjusting the tension of the bobbin thread

If the desired stitching cannot be achieved after adjusting the upper thread tension, adjust the tension of the bobbin thread. The tension of the bobbin thread can be adjusted by turning the slotted-head (−) screw on the bobbin case (gray) for bobbin work.

①Do not turn the phillips screw (+).
②Adjust with a screwdriver (small).

To increase the tension of the bobbin thread, turn the slotted-head (−) screw 30° to 45° clockwise.

To decrease the tension of the bobbin thread, turn the slotted-head (−) screw 30° to 45° counterclockwise.

Simple line drawing of a car's front wheel and side door (no text or symbols)

Note

- Turning the screw on the bobbin case (gray) may push up the spring plate, as shown below. If this occurs, gently press down the spring plate with a screwdriver so it is lower than the top surface of the bobbin case (gray), and then insert the bobbin case into the machine.

Illustration of a hand using a pipette to apply a small object onto a surface (no text or symbols present)

①Spring plate

CAUTION

• DO NOT adjust the position of the phillips (+) screw on the bobbin case (gray) as this may result in damage to the bobbin case, rendering it useless.
• 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.

Note

- If the bobbin thread tension is tight, the thread cannot be passed through the tension spring when the bobbin is installed in the bobbin case. (Refer to "When tension is not applied to the bobbin thread" on page 11.)

Troubleshooting

Several solutions for minor problems are described below. If the problem persists, contact your nearest authorized retailer.

■The thread was accidentally cut automatically and the bobbin thread is caught inside the machine

1 Cut the thread near the fabric above the needle plate, and then remove the fabric.
