Sewing basics

Let’s try making a straight stitch, the most basic kind of sewing.

1. Make sure the upper thread and the bobbin thread have been correctly installed.
   See pages 11 to 12 for instructions about threading the upper thread and the bobbin thread.
2. Turn the hand wheel toward you (counterclockwise) to raise the take-up lever and the needle to their highest position. Pull the upper thread and the bobbin thread together so they come out behind the needle by about 10 cm. Make sure that the upper thread and the bobbin thread come out beneath the pressure foot.
3. Turn the pattern selection dial to select the stitch pattern.When rotating the Pattern selection dial, make sure the needle is in the raised position. Here, “A” sets the machine for “straight stitch.”
4. Raise the presser foot and place the fabric under it.When you use the sewing machine for the first time, remove the test piece (this is a piece of fabric used for test sewing when the machine is shipped from the factory).
5. Turn the hand wheel toward you (counterclockwise) to lower the needle to the position where you wish to start sewing.
6. Lower the presser foot lifter to fasten the fabric.
7. Make sure that the Foot pedal / Automatic switch is set to “” and the adaptor is plugged in.The light will illuminate when the adaptor is plugged in.
8. Start sewing again while pressing the fabric gently.
   How to use the foot pedal/ automatic switch
   • Stop the sewing machine /Foot pedal switch.
   • The machine will automatically run slowly.
   • The machine will automatically run quickly.
   • When using the foot pedal(one speed foot pedal), make sure the Foot pedal/Automatic switch is “” position. The machine will run only while you are pressing the pedal with your foot.
9. When you have finished sewing, rotate the hand wheel toward you (counterclockwise) to raise the needle and the take-up lever, and the presser foot lifter.
10. Remove the fabric and cut the thread with the thread cutter.Hints: If the thread is caught and you cannot remove the fabric, rotate the hand wheel back and forth slightly to make it easier to remove the thread and the fabric.

Note

• When reverse stitching
  The machine will sew in reverse only while the reverse lever is pushed down.
  * The thread is unlikely to become loose if you reverse stitch when you start or end sewing.
• When changing sewing direction
  1. Stop the sewing machine.
  2. Lower the needle by turning the hand wheel toward you (counterclockwise) to insert the needle into the cloth.
  3. Raise the presser foot lifter to raise the presser foot.
  4. Rotate the fabric
  5. Lower the presser foot lifter to begin sewing again.

Various types of sewing

You can choose from 12 different stitches by turning the pattern selection dial.

If you want to change the stitch while sewing

1. Stop the machine, rotate the hand wheel toward you (counterclockwise), and move the take-up lever and the needle to their highest position.Caution
   Do not turn the pattern selector dial while the machine is running or while the needle is in the fabric. Doing so can result in the machine damage.
2. Turn the pattern selection dial to align with the mark indicating the desired stitch.Hints
   • Stitches can be used when sewing two layers of fabric, too.
   • The straight stitch is best when you are sewing soft fabrics or silks.

When sewing tubular items

Slide tubular items like sleeves and trouser legs over the arm so you can sew them.

Hints
It is helpful to remove the auxiliary table when you sew tubular items like sleeves.

   Align the presser foot pin so it lines up right under the holder.
4. Lower the presser foot to lower the presser foot holder.
5. Raise the presser foot lock lever to secure the presser foot to the presser holder.
6. Raise the presser foot lifter, pass the upper thread and the bobbin thread through the buttonhole presser foot so they come out from the side.

2. Attach the buttonhole presser foot and place the fabric beneath the presser foot.
3. Draw both of needle and the bobbin thread to the left. The slider frame of a buttonhole is removable. Move the slider frame toward you so that the top mark on the slider meets the start mark.
4. Choose the buttonhole length as per your requirement by stopping the slider frame movement. Please see the following picture.

   • Caution: Stop the sewing machine and raise the needle and the thread tension lever to their highest positions when you rotate the pattern selection dial. Turning the dial while the machine is running can damage the machine.
10. When you have finished sewing, pull the fabric and cut the thread.
11. To keep the thread from unraveling, pull out the upper thread from the rear of the fabric and tie it off with the bobbin thread.
12. Insert a dress pin in front of the bar tacking and use a standard seam ripper to cut the buttonhole open.Caution
    Be careful not to put your hand in front of the seam ripper. Doing so can result in injury.
