1. Push down the lever for the desired pressure; for light fabrics set lever at 3, set at 2 for medium fabrics and at 1 for heavy fabrics.

2. Insufficient pressure may cause poor feeding, skipped stitches or difficulty in guiding the fabric.

To adjust the presser foot pressure, use the lever behind the cover of the lamp. Loosen the stop screw of the lamp cover to open it.

3. When darning or sewing freehand embroidery, release the pressure by setting the lever to O.

After adjusting the presser foot pressure and closing the lamp cover, tighten up the stop screw.

The lever is usually adjusted at 2.

TO START SEWING

Important hints:

1. Raise the take-up lever to its highest position before starting and after stopping sewing.

2. Hold both threads about 10 cms to the rear of the machine for the first two or three stitches.

3. Sufficient fabric should be placed under needle before lowering the presser foot.

4. Depress foot/speed control and start to sew.

5. Test the machine stitches on a scrap of fabric you plan to use, adjusting the machine for the length of the stitch and tension suitable to your fabric.

6. Separate the machine from the power system if you leave it unsupervised.

Attention:

1. When turning the balance wheel manually, always turn it toward you.

2. Guide the cloth gently with your hand.

3. To prevent breaking needles, always raise the needle out of the fabric when you stop sewing.

SLIDE SPEED CONTROL

The sewing speed is achieved by using the slide Control in conjunction with the Foot

Control. The Slide Speed Control is moved horizontally to determine the ‘zone’ of speed required, the far right, being very slow (minimum), through to the left, building up to fast being the maximum. However, the final speed, within the chosen ‘zone’ can be further determined by the amount of pressure applied to the Foot Control.

- 19 -

HOW TO FINISH STITCHES

1. Sew to the edge of seam.

2. Push the reverse button and sew in reverse for about 3-4 cms.

3. Raise needle into its highest position.

4. Lift the presser foot and pull the fabric out of the back of the machine.

Cutting thread slot

5. Cut threads as shown on the thread cutter.

- 20 -

STRAIGHT STITCH

1. This type of stitching is used most frequently.

2. The zigzag presser foot can be used for both straight and zigzag sewing.

3. For sewing light fabric, use a smaller stitch size. (Refer to page 17 for dial setting).

ZIGZAG SEWING

Pattern selector position

Satin stitching can be used for sewing initials, patterns, appliqué, etc.

- 21 -

OVERCASTING

Use these stitches for oversewing rough edges.

STRAIGHT AND ZIGZAG STRETCH STITCHES

Use this stitch with knitted, tricot or other stretchy fabrics.

The stitch enables your seam to stretch with out breaking the thread.

- 22 -

BLIND STITCH

1. Fold fabric as shown.

2. Finish the seam as shown.

- 23 -

Adjust the width to obtain the correct seam.

Wrong: Needle is not piercing edge to fold at all.

Needle pierces the edge of fold too much.

Correct seam.

- 24 -

BUTTON SEWING

Utilise the foot of sewing of buttons.

Match

(Use drop feed see page 15)

1. Lower drop feed.

2. Place button presser foot in position and attach it firmly.

3. Place the button between presser foot and fabric and lower the presser foot.

4. Manually turn hand wheel towards you, ensuring that the needle enters into both holes of button without obstruction. (Increase or decrease width setting).

5. Sew about 7 stitches.

6. Pull both threads to the underside and tie them together.

BINDING

To sew fabrics edge select the multi-zigzag stitch.

- 25 -

ZIPPER SEWING

Utilise the foot of closing zipper.

Select straight stitch.

1. Zipper foot is designed to sew close to a raised edge, thus preventing sewing on zipper.

2. Place zipper foot in position and attach firmly.

3. Fold the fabric about 2 cm and place the fabric under foot.

1. To sew the left side of the zipper, set the zipper on the right side of the needle.

2. To sew the right side of the zipper, set it on the left side of the needle.

Sew as illustrated.

- 26 -

BUTTONHOLE SEWING

Set the stitch length dial.

Pattern selector dial Steps

Before sewing, fit buttonhole foot as shown.

Setting

1. Set dial to “A“ position

2. Sew left side

3. Raise the needle

4. Set dial to “B“ position

5. Sew 5-6 stitches

6. Raise the needle

7. Set dial to “C“ position

8. Sew right side

9. Raise the needle

10. Set dial to “D“ position

11. Sew 5-6 stitches

12. Raise the needle

Cut buttonhole along centre with cutter as shown.

- 27 -

HEMMING

1 mm

3 mm

20 mm

1. Raise the foot and the needle to its highest position. Replace the foot with the picot foot.

2. Fold over the fabric edge by about 3 mm and place it under the foot. Secure the folded edge with a few stitches. Take out the workpiece and draw the hem into the picot foot through pulling the threads.

3. Lower the foot and sew the hem.

4. While sewing fold the fabric to the left a little and allow it to run into the hemmer foot.

5. Make sure that the fabric does not move under the right half of the foot. The fabric must be fed into the scroll of the hemmer sufficiently so that the workpiece edge runs freely through the groove under the foot.

Only suitable materials can be used and some practice may be necessary to achieve the best results.

- 28 -

TWIN NEEDLE (Optional)

Put in the twin needle with the flat side backwards.

Thread the machine as for normal sewing, leading both threads to needle and passing their ends separately through its eye.

Sewing width should not exceed the third widest stitch width, as this will break the needles.

ATTENTION: When using the twin needle, adjust the stitch width to maximally 3.

Adjusting the stitch width to a higher number causes the needle to break.

EMBROIDERY

(Use drop feed see page 15)

Remove the presser foot and lower feed dog.

Lower feed dog and move the hooped fabric slowly in the desired direction until the fabric has been embroidered.

- 29 -

QUILTER (Optional)

1. Slide the arm through the hole on top of the pressure foot holder.

2. Move the quilter to the required stitch distance.

SEAM GUIDE

1. Use the seam guide to sew long seams of an equal distance from the edge of the fabric.

2. Screw the guide on the right side of the needle plate and adjust the desired distance.

3. While sewing, the edge of the fabric must touch the guide.
