THREADING THE MACHINE

Winding the bobbin

1 Pull up the spool pin and put a spool of thread on this pin.

2 While holding the thread from the spool with your right hand, pass the thread toward you, in the groove on the thread guide. Then, pass the thread around the pre-tension disk and pull the thread in completely.

3 Pass the end of the thread through the hole on the bobbin from the inside of the bobbin.

4 Put the bobbin onto the bobbin winder shaft and slide the bobbin winder shaft to the right. Turn the bobbin clockwise, by hand, until the projection slides into the notch of the bobbin.

  • Make sure to pull out 7 to 10 cm (3-4 inches) of thread from the hole on the bobbin.

5 Turn on the machine.

6 While holding the end of the thread, gently press the foot controller to wind the thread around the bobbin a few times. Then stop the machine.

7 Trim the excess thread above the bobbin.

  • Leave 1 cm (1/2 inch) of thread from the hole on the bobbin.

8 Press the foot controller to start.

9 When the bobbin seems full and begins spinning slowly, take your foot off the foot controller.

10 Cut the thread, slide the bobbin winder shaft to the left and remove the bobbin.

Note

  • 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 winder shaft to the right.

Lower threading

1 Prepare the bobbin wound properly before threading the lower thread.

  • See page 13 for the details about bobbin winding.

2 Raise the needle by turning the handwheel toward you (counterclockwise) and raise the presser foot lever.

3 Remove the bobbin cover by sliding it and lift toward you.

4 Put the bobbin in so the thread comes out in the direction shown by the arrow.

5 Hold the end of the thread, push the bobbin down with your finger, and then pass the thread through the slit, as shown.

  • If the thread is not correctly inserted through the tension-adjusting spring of the bobbin case, it may cause incorrect thread tension.

6 Replace the bobbin cover. Put the projection into the bobbin race retainer groove and push closed.

  • Make sure that the end of the thread comes out from the cover toward the rear of the machine (as shown in the illustration).
  • Draw up the lower thread before starting sewing. Refer to “Drawing up the lower thread” on page 21 after threading the upper thread.

Upper threading

1 Turn off the machine.

2 Raise the presser foot lever.

3 Raise the needle by turning the handwheel toward you (counterclockwise) so that the mark on the wheel points up.

  • If the needle is not correctly raised, the sewing machine can not be threaded.

4 Pull up the spool pin and put a spool of thread on this pin.

5 While holding the thread from the spool with your right hand, pass the thread toward you, in the groove on the thread guide.

  • Make sure that the spring in the groove catches the thread.

6 Feed the upper thread as shown in the following illustration.

7 Make sure you guide the thread through the thread take-up lever from right to left as shown in the following illustration.

8 Put the thread behind the guide above the needle.

  • The thread can easily be passed behind the needle bar thread guide by holding the thread in your left hand, then feeding the thread with your right hand.

9 Thread the needle from front to back leaving a thread tail of about 5 cm (2 inches).

  • If your sewing machine is equipped with a needle threader, use the needle threader to thread the needle (see next section).

Note

  • 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.

SEWING BASICS

Starting sewing

1 Turn on the machine.

2 Raise the needle by turning the handwheel toward you (counterclockwise) so that the mark on the wheel points up.

3 Turn the pattern selection dial to select a stitch (see page 11).

4 Change the presser foot (see page 10).

5 Raise the presser foot lever.

6 Place the fabric under the presser foot, pass the thread under the presser foot, and then pull out about 5 cm (2 inches) of thread toward the rear of the machine.

7 While holding the end of the thread and the fabric with your left hand, turn the handwheel toward you (counterclockwise) with your right hand to lower the needle to the starting point of the stitching.

8 Lower the presser foot lever.

9 Slowly press down on the foot controller.

  • The machine starts sewing.

10 Take your foot off the foot controller.

The machine stops sewing.

  • You can use reverse sewing for back tacking and reinforcing seams by pressing the reverse sewing lever. Refer to “Reverse sewing lever” on page 12 for the details.

11 Raise the needle by turning the handwheel toward you (counterclockwise).

12 Raise the presser foot lever.

13 Pull the fabric to the left side of the machine, and then pass the threads through the thread cutter to cut them.

Trial sewing

A trial piece of fabric should be sewn. Use a piece of fabric and thread that are the same as those used for your project, and check the thread tension and stitch length and width.

Changing the sewing direction

Stop the machine with the needle in the fabric at the point where you want to change the sewing direction, and then raise the presser foot lever. Using the needle as a pivot, turn the fabric, lower the presser foot lever, and then continue sewing.

Sewing thick fabrics

If the fabric does not fit under the presser foot

If the fabric does not fit easily under the presser foot, raise the presser foot lever even higher to bring the presser foot to its highest position.

Sewing thin fabrics

When sewing thin fabrics, the stitching may become misaligned or the fabric may not feed correctly. If this occurs, place thin paper or stabilizer material under the fabric and sew it together with the fabric. When you have finished sewing, tear off any excess paper.

Sewing stretch fabrics

First, baste the pieces of fabric together, and then sew without stretching the fabric.

Stitching cylindrical pieces

Removing the flat bed attachment makes it easier to sew cylindrical pieces such as cuffs and pant legs, or hardto-reach areas.

1 Slide the flat bed attachment to the left to release it.

  • With the flat bed attachment removed, free-arm sewing is possible.

2 Slide the part that you wish to sew onto the arm, and then sew from the top.

Sewing with a twin needle (Option)

We have designed your machine so you can sew with this needle and two top threads. You can use the same color or two different colors of thread for making decorative stitches.

  • Attaching the twin needle

Attach the twin needle in the same way as a single needle (see page 8–9). The flat side of the needle should face toward the back and the rounded side should face toward you.

SEWING BUTTONHOLES

Making a buttonhole

Memo

  • We recommend that you practice making a buttonhole on a scrap piece of fabric before you try it on an actual garment.
  • When making buttonholes on soft fabrics, place a stabilizer material on the underside of the fabric.

1 Using tailor’s chalk, mark the position and length of the buttonhole on the fabric.

2 Attach the buttonhole foot and push the frame back until it stops with the plastic insert at the front of the frame.

3 You need to sew the front bar tack first. Line the bar tack mark under the center of the presser foot and match it up to the two lines on the presser foot.

  • Making a Buttonhole

  • Securing the Stitching and Cutting the Buttonhole

1 To secure the stitching, turn the material 90 degrees counterclockwise and sew straight stitches to the end of the front bar tack of the buttonhole.

2 Remove the material from the machine. We recommend that you put pins across both ends of the buttonhole to prevent the stitches from being cut.

3 Cut an opening in the middle of the buttonhole with the seam ripper tool. Be careful not to cut through any stitches.

Adjusting buttonholes

If the stitching on the two sides of the buttonhole is not the same, you can make the following adjustments.

1 After sewing the left side of the buttonhole, stitch the right side and observe the feeding.

2 If the left side is too open or tight compared with the right side, adjust the buttonhole fine-adjustment screw as described in the following paragraphs.

If the left side is too open, turn the buttonhole fine-adjustment screw with a large screwdriver in the “–” direction. If the left side is too tight, turn the buttonhole fine-adjustment screw with a large screwdriver in the “+” direction.

  • This adjustment ensures both sides of the buttonhole are the same.

USING ATTACHMENTS AND APPLICATIONS

Zipper insertion

You can use the zipper foot “I” to sew different types of zippers, and can easily position it to the right or left side of the needle.

When sewing with the zipper on the right side, attach the shank to the left pin of the zipper foot. When sewing with the zipper on the left side, attach the shank to the right pin of the zipper foot.

1 Prepare the fabric with the zipper basted on the wrong side.

2 Turn off the machine. Attach the zipper foot “I”.

3 Turn on the machine.

4 With the right side of the fabric facing up, continue sewing with the zipper on the right side of the presser foot.

  • Sew the stitching in order, from 1 to 3.

5 When you have finished sewing, remove the basting stitching.

Gathering

1 Loosen the tension of the upper thread so that the lower thread lies on the underside of the material.

2 Sew a single row (or many rows) of straight stitches.

3 Pull the lower threads to gather the material.

Darning

1 Turn off the machine. Place the darning plate on the needle plate, then turn on the machine.

2 Either remove both the presser foot and presser foot holder assembly and then lower the presser foot lever.

3 Put the section you want to darn under the presser foot together with fabric for reinforcement.

4 Turn on the machine.

5 Begin sewing by alternating between gently drawing the work away from you and pulling it toward you.

6 Repeat this motion until the section being darned is filled with parallel lines of stitching.
