Twin-Needle Sewing
Your sewing machine is designed for twin-needle sewing which allows you to sew using two upper threads. You can use the same color or two different colors of thread for decorative stitches. Twin-needle sewing works well with these stitches: the Straight Stitch (6-10)-and the Zigzag Stitch (2). Be sure that the two upper threads used for threading the twin needle have the same weight. If the threads do not have the same weight, the stitching may not be consistent.
INSERTING THE TWIN NEEDLE
Insert the twin needle in the same way that a single needle is inserted. (Refer to page 6.) The flat side of the needle should face toward the back and the rounded side should face toward you.
SETTING THE EXTRA SPOOL PIN
Place the extra vertical spool pin in the hole found on the top right-hand side of the machine. Place the second spool of thread on this pin as shown in fig. A.
Extra spool pin
TWIN NEEDLE THREADING
Each needle should be threaded separately.
1. Threading the Right Needle Follow the same instructions for single needle threading. See page 15 for more details.
2. Threading the Left Needle Thread the left needle in the same way as the right needle was threaded, but do not pass the thread through the thread guide above the needle before passing it through the eye of the left needle as shown in fig. B.
Right needle thread passes through this guide.
Left needle thread passes in front of this guide.
Thread Tension
Thread tension will affect the quality of your stitches. It may need to be adjusted when you change fabric or thread type.
NOTE:
It is recommended that a test sample be made on a fabric scrap before sewing on your project.
The basic thread tension setting is “5”.
Possible problems and how to correct them.
A Upper tension is too tight.
Locks appear on the surface of the fabric.
A-1 Upper tension control dial
Decrease the tension by turning the dial to a lower number.
B Upper tension is too loose.
Locks appear on the reverse side of the fabric.
B-1 Upper tension control dial
Increase the tension by turning the dial to a higher number.
Reverse
Surface
NOTE:
The bobbin thread tension has already been adjusted at the factory for general use. For most sewing applications, no adjustment is needed.
When sewing with thin thread on thin fabrics, the thread tension may not be adjusted adequately with the upper tension control dial. Therefore, the thread tension must be adjusted according to the procedure described below.
C Bobbin tension is too loose.
Locks appear on the surface of the fabric.
Decrease the thread tension by turning the dial to a lower number. If the result is still not satisfactory, then adjust the bobbin thread tension as explained in C-1
C-1 Bobbin
Increase the tension in the bobbin by turning the screw with a small screwdriver in a clockwise direction. However, do not turn the screw more than one full turn.
Remember to return the screw to its original setting before starting your next project.
D Correct tension
Correct tension is important since too much or too little tension will weaken your seams or cause puckers in your fabric.

Zigzag Stitching
ZIGZAG STITCH
Set the pattern selection dial to the appropriate Zigzag Stitch (2, 3 or 4) with the desired width.
It is recommended to sew using the Straight Stitch at the beginning and end of the Zigzag Stitches.
ZIGZAG (SATIN) STITCH
The Satin Stitch can be used for making decorative stitches. Set the pattern selection dial to the Zigzag (Satin) Stitch (5).
Blind Hem Stitching
The Stretch Blind Stitch is used to finish the edge of projects made with stretch fabrics without the stitch showing.
1. Set the pattern selection dial to 12.
2. Both the threads should be the same color as the fabric.
3. Fold back the fabric to the desired location of the hem as shown in fig. A. Then, fold the edge of the fabric as in fig. B. Leave a 6 mm (1/4") overlap at the edge.
4. Sew on the fold as in fig. C.
5. When the fabric is unfolded you will have a Stretch Blind Stitch hem as shown in fig. D.
Elastic Stitching
The Elastic Stitch can be used in 3 ways: mending, sewing elastic or joining fabric. Each is explained below. Set the pattern selection dial to 14.
MENDING
1. Place the reinforcement fabric under the tear to be mended.
2. Following the line of the tear, sew using the Elastic Stitch as illustrated in fig. A.
SEWING ELASTIC
1. Place the elastic on the fabric.
2. As you sew, stretch the elastic both in the front and behind the presser foot as shown in fig. B.
JOINING FABRIC
The Elastic Stitch can be used to join two pieces of fabric together and is very effective when sewing knitted fabrics. When nylon thread is used, the stitch will not be visible.
1. Place the edge of the two pieces of fabric together and center them under the presser foot.
2. Sew them together using the Elastic Stitch taking care to keep the two fabric edges close together as shown in fig. C.
Shell Tuck Stitching
The Shell Tuck Stitch can be used to sew a picot (lace-like) edge on a lightweight fabric.
1. Set the pattern selection dial to 13.
2. Use a tighter thread tension than normal.
3. At a slow speed, sew the fabric on the bias, placing it under the presser foot so that the straight stitches are sewn on the seamline and the zigzag stitches are sewn slightly over the folded edge.
Making a Buttonhole
NOTE:
1. It is recommended to practice making a buttonhole on a scrap piece of fabric before attempting it on the actual garment.
2. When making buttonholes on soft fabrics, place stabilizer material on the underside of the fabric.
Buttonhole-making is a simple process that provides reliable results.
MAKING A BUTTONHOLE
1. Using tailor’s chalk, mark the position and length of the buttonhole on the fabric.
2. Attach the buttonhole foot and push the outside frame back until the sliding insert is in the front.
3. The front bar tack will be sewn first. Place the fabric under the presser foot so that the middle of the front of the tailor’s chalk line is directly in the center of the presser foot and aligned with the two red lines on the insert as shown below.
Front of chalk mark
Red lines
MAKING A BUTTONHOLE
Step a (Front end of buttonhole)
1. Set the pattern selection dial to a.
2. Lower the presser foot and sew 5 to 6 stitches.
3. Stop the machine when the needle is at the left side of the stitches and raise the needle from the fabric.
Step b (Left side)
1. Turn the pattern selection dial to b.
2. Sew the predetermined length of the tailor’s chalk line.
3. Stop the machine when the needle is at the left side of the stitch and raise the needle.
Step c (Back end of buttonhole)
1. Turn the pattern selection dial to c (same as a).
2. Lower the presser foot and sew 5 to 6 stitches.
3. Stop the machine when the needle is at the right side of the stitch and raise the needle from the fabric.
Step d (Right side)
1. Set the pattern selection dial to d.
2. Sew the right side until the needle reaches the stitches formed in step a.
SECURING THE STITCHING AND CUTTING THE BUTTONHOLE
1. To secure the stitching, turn the material 90 degrees counterclockwise, set the pattern selection dial to the Straight Stitch (6-10) with the desired length and sew to the edge of the front bar tack.
2. Remove the fabric from the machine. It is recommended that pins be placed across both ends of the buttonhole as protection against cutting the stitches.
3. Cut an opening in the middle of the buttonhole with a seam ripper tool. Be careful not to cut through any stitches.
Buttonhole Fine Adjustment
If the stitching on the two sides of the buttonhole do not appear uniform, the following adjustments can be made.
1. After sewing the left side of the buttonhole, stitch the right side and observe the feeding.
2. If the right side is too coarse or fine compared to the left side, adjust the buttonhole fine-adjusting screw as described below.
If the right side is too coarse, turn the buttonhole fine-adjusting screw with the enclosed large screwdriver in the – direction.
If the right side is too fine, turn the buttonhole fine-adjusting screw with the enclosed large screwdriver in the + direction.
This adjustment allows both sides of the buttonhole to appear uniform.
