Drawing up bobbin thread
Raise the presser foot and hold the needle thread lightly with your left hand.
Turn the hand wheel slowly towards you with your right hand until the
needle goes down and continue turning the hand wheel until the take-up
lever is at its highest position.
Lightly draw up the needle thread, forming a loop of the bobbin thread.
Pull 15cm (6 inches) of both threads back and under the presser foot.
Balancing top thread tension
The top thread and the bobbin thread should interlock in
the center of two layers of fabric in straight seams.
Set the desired number of the thread tension dial at
setting mark.
Tighten the needle thread tension by moving the dial to
a higher number.
Loosen the needle thread tension by moving the dial to
a lower number.
NOTE: In order to obtain better zigzag stitches, the top thread tension should be slightly looser than the bobbin
thread tension. That means the top thread should appear slightly on the reverse side of the fabric, but the
bobbin thread should not appear on the top side of the fabric.

Needle, thread and fabric chart
Your fabric will determine the choice of a needle and thread. The following table is a practical guide to needle and thread
selection.
Always refer to it before a new sewing project. And be sure to use the same size and type of thread in the bobbin as in the top
thread supply.

CAUTION
Always disconnect the machine from power supply by removing the
plug from the wall-outlet.
Changing the needle
1. Raise the needle by turning hand wheel toward you and
lower the presser foot.
2. Rotate the needle clamp screw toward you (counter-
clockwise) to loosen the needle.
3. Remove the needle from the clamp.
4. Insert the new needle into the needle clamp with the flat
side away from you.
5. When inserting the needle into the clamp, push it up as far
as it will go.
6. Tighten the clamp screw clockwise firmly with the
screwdriver.
* Check your needles frequently for barbed or
blunted points.
Snags and runs in knits, fine silks and silk-like
fabrics are permanent and are almost always caused
by damaged needle.
NOTE: Tighten snugly, but do not over tighten.
Helpful Hint: Placing a scrap of fabric under the presser foot and
lowering the presser foot makes it easier to change the needle and will
preclude dropping the needle into the needle plate slot.
Change the needle often. As a general rule,
needles, should be changed every 6-8 hours of
actual stitching time.

Pattern selector dial
Select the desired pattern at the setting mark by turning the pattern selector dial.
Selecting stretch stitch patterns
When sewing stretch stitches, set the stitch length dial at “SS”.
When forward and reverse feeds become unbalanced depending upon the type of fabric, correct as follows.
When patterns are compressed, correct it by turning the dial toward “+”.
When patterns are drawn out, correct it by turning the dial toward ”-”.
Stitch length dial
The higher the number, the longer the stitch length. Note: when set to “0”, the machine will not feed the fabric.

Useful sewing tips
Various ways to achieve better sewing results are described below. Refer to these tips when sewing.
1. Trial sewing
Use different stitch width and length for trial sewing. When you have finished, select the best looking stitch length for
correct sewing.
For the trial sewing, 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. Since the results differ depending on the type of stitching and the number of fabric layers sewn,
perform the trial sewing under the same conditions that will be used with your project.
2. Changing the sewing direction
Stop the machine and turn the hand wheel toward you to
bring the needle down into the fabric. Raise the presser
foot.
Pivot the fabric around the needle to change sewing
direction as desired. Lower the presser foot and continue
sewing.
3. Sewing curves
1). Stop sewing, and then slightly change the sewing direction to sew around the curve.
2). When sewing along a curve while using a zigzag stitch, select a shorter length in order to obtain a finer stitch.
4. Sewing thick fabrics
If the fabric does not fit under the presser foot
Raise the presser foot even higher to bring the presser foot to its highest position. Then place the fabric under the presser
foot. (See page 4 to raise the presser foot.)
5. Sewing elastic fabric or the fabric that is easy to cause skipping stitches
Use ball point needle and longer stitch length. If necessary, add a layer of stabilizer under the fabric for better sewing.
6. Sewing thin fabric or silk
Some fine fabrics, such as silk, can be slippery and more difficult to handle. It can be helpful to place a lightweight
stabilizer underneath the fabric for easier sewing.
7. Sewing stretch fabrics
First, baste the fabrics together, and then sew without stretching the fabric.
8. Free arm sewing
When sewing trousers, sleeve cuffs or other hard-to-reach areas, use the free-arm sewing function (for details about setting
the machine for free-arm sewing, refer to page 4).

UTILITY STITCHES
13
Straight stitch
Raise the presser foot and position the fabric next to a stitching guide line on
the needle plate.
Lower the needle into the fabric.
Lower the presser foot and smooth the thread towards the back. Depress the
foot control.
Gently guide the fabric along the guide line letting the fabric feed by itself.
For securing the ends of seams, press the reverse stitch lever and sew several
reverse stitches.
Raise the presser foot and remove the fabric, drawing the threads to back.
The threads are cut the proper length for starting the next seam.

Zigzag stitch
Simple zigzag stitching is widely used for overcasting, sewing on buttons, decorative stitching, etc.
The zigzag stitch can also be used on the seam allowance to prevent fabrics from fraying at raw edges.
Overedge stitch
Overedge stitch will be done most successfully when the right side stitches of zigzag fall slightly off the edge of the fabric.

UTILITY STITCHES
15
Multi-step zigzag stitch
To help prevent fabrics from unraveling, place the fabric
under the presser foot so the right-hand side of the stitches
falls at the edge of the fabric.
This stitch can also be used for elastic insertion, decorative
stitching, and more.
Straight stretch stitch
The stitch is sewn with two stitches forward and one stitch
backward forming a seam that does not rip easily.

Sewing buttons
Position your fabric and button under the presser foot. Lower presser foot. Turn the handwheel to make sure needle
clears both left and right openings of button. Sew 10 stitches across.
When attaching four-hole buttons, first sew the two holes closest to you. Then, slide the button so that the needle
goes into the two holes toward the rear of the sewing machine, and then sew them in the same way.
To secure thread, cut the upper thread with 25cm of excess, wind it around the thread between
the button and the fabric, and then tie it securely.
Machine Setting
Lower the feed teeth
NOTE: 1. Lower the feed teeth (refer to page 4).
After you finish sewing, set drop feed lever to
original position, and turn the handwheel one full turn
to re-engage feed teeth.
2. You do not have to adjust the stitch length dial.
