Frequently Asked Questions - W979 White

How do I thread the machine?

Raise the presser foot and needle to the highest position. Follow the numbered threading path on the machine: from spool pin, through thread guide, around tension discs, up to take-up lever, then down to needle. Use the automatic needle threader if available (models 979, 972).

Why does my machine skip stitches?

Common causes: needle is not fully inserted (flat side away from you), needle is bent or blunt, machine is not threaded correctly, thread caught in shuttle, or fabric is knit/synthetic requiring a stretch stitch needle. Check page 11 of manual.

How do I wind the bobbin?

Place thread on spool pin, pass through thread guides, pull end through hole in bobbin. Push bobbin winder shaft right until it clicks, hold thread end, step on foot control. Bobbin stops when full; push shaft left to remove.

Why does my bobbin thread break?

Ensure bobbin is threaded correctly (rotates counter-clockwise), and lint is removed from bobbin case and shuttle area. See page 10 and 41 for cleaning instructions.

How do I adjust the top thread tension?

Set tension dial to 'AUTO' or 3 for normal sewing. For straight stitch, if top thread appears on bottom (loose top tension) or bobbin thread appears on top (tight top tension), adjust accordingly. For zigzag, top thread may show on bottom; bobbin thread should never show on top.

How do I sew a buttonhole?

Use automatic one-step buttonhole foot: insert button in carrier, place fabric under foot, lower buttonhole lever, push lever away, and sew. Machine completes entire buttonhole automatically. For 5-step buttonhole (model 970), follow sequence of bartack, stitch forward, bartack, stitch backward, stitch forward.

Can I use twin needles?

Yes, on models 979 and 972. Place two spools on spool pins, thread both threads separately through double guides, and thread each needle. Never set stitch width above the twin needle mark to avoid breaking needles.

How do I clean my sewing machine?

Unplug machine. Remove needle plate and bobbin case. Clean feed dogs and shuttle area with lint brush. Apply one drop of sewing machine oil on shuttle race as indicated by arrows. Replace bobbin case aligning projection with spring, then needle plate.

What should I do if the machine jams?

Turn off power, unplug. Remove fabric gently. Check for thread caught in shuttle area and clean thoroughly. Ensure needle is not damaged. For electronic model, if machine stops with three beeps, remove jam cause and step on foot control to resume.

How do I convert to free-arm sewing?

Pull the extension table off to the left. The machine becomes a free-arm model suitable for sewing cuffs, sleeves, and other tubular pieces. To return, slide the extension table back in place.

ADJUSTING TOP THREAD TENSION

STRAIGHT STITCHING

The quality of your stitching is largely determined by the balanced tension of both top and bobbin threads. The tension is well balanced when these two threads 'lock' in the middle of layers of fabric you are sewing.

Set the tension control at the "AUTO" position or 3 for normal sewing.

If, when you start to sew, you find that the stitching is irregular, you will need to adjust the tension control. Make any adjustments with presser foot 'down'.

ZIGZAG STITCHING

The top thread may appear on the bottom depending on the thread, fabric, type of stitch and sewing speed, but the bobbin thread should never appear on the top of the fabric.

PUNTADA INVISIBLE

THREE-STEP ZIGZAG

This is a strong stitch because it makes three short stitches where the normal zig-zag makes only one.

For this reason it is highly recommended for overcasting all types of fabrics.

It is also ideal for mending tears, patching, sewing towelling, patch-work and attaching flat elastic.

ZIG-ZAG DE TRES PUNTADAS

Double-action stitch is ideal for producing flat overlapped seams on almost any type of fabric and a bolder effect will result from sewing with contrasting thread.

PUNTADA DE ACCION DOBLE

LINGERIE STITCH

Lingerie stitch is for seaming and overcasting sheer, soft fabrics in one operation. It also produces a delicate shell hem on lingerie and other fine garments.

SEAM AND OVERCAST IN ONE

Place the right sides of the fabric together and position under the presser foot so that the zig-zag part of the stitch sews just over the raw edge.

Illustration

1: Regular lingerie stitch

II: Four-point lingerie stitch

SHELL HEM

Turn under the raw edge and press. Place the fabric right side up so that the zig-zag part of the stitch sews just over the folded edge, pulling the fabric in to form a shell hem. Trim away excess fabric close to the stitching line.

Regular shell stitch

Regular shell stitch produces a tiny shell hem on lingerie and other fine garments.

Four-point shell stitch

If bigger size of shell pattern is desired, use four-point shell stitch.

:AGGOTING

his is a popular decorative stitch (used in sleeves or fronts of blouses and dresses). To attach two separate pieces of fabric together, leave a little space in between. To prepare the fabric:

old under the seam allowances on the cut edges, and press. Baste folded edges to stabilizer with about 1/8" (0.3 m) space between. Stitch over the 1/8" (0.3 cm) allowance, just catching the fabric fold on both sides with needle. Remove bastings and stabilizer; press.

STRETCH STITCHES

Stretch stitches are mainly for use on knit, or stretchable abrics, but can also be used on ordinary materials.

ADJUSTING STRETCH STITCH BALANCE

Stitch length/super (stretch) stitch control should be at a mark for most materials. Depending upon the type of fabric used, you may need to adjust this Control to match forward stitches of stretch sewing with reverse motion stitches. If the stitches are too open, turn the Control to S position; if the stitches overlap, turn the Control to L position.

Illustration

I: Ric-Rac Stitch

II: Smocking Stitch

Triple straight stitch is far stronger than ordinary straight stitch because it locks three times-forwards, backwards and forwards.

It is particularly suitable for reinforcing the seams of sportswear in stretch and non-stretch fabrics, and for curved seams which take a lot of strain.

DECORATIVE EMBROIDERY DESIGNS

Your Machine will produce a wide range of beautiful decorative embroidery patterns as illustrated on the Stitch indicator panel.

Simply select the design of your choice and proceed to sew, the pattern will be produced automatically. The final effect of each design will depend on stitch length setting.

TIPS ON DESIGN STITCHING

1. Always make a practice design on a scrap of the fabric you plan to use.
2. Start with a full bobbin and plenty of thread on the spool to avoid running out of thread in the middle of your design.
3. Reduce the top thread tension slightly.
4. On a very soft fabric you may want to use a stabilizer backing or organdy that can be cut away afterwards.

BUTTONHOLE MAKING

AUTOMATIC ONE-STEP BUTTONHOLE

(Model 979, 972 only)

1. Carefully mark the position of buttonhole on your garment.
2. Slide open the button carrier and insert the button.
3. Attach the buttonhole foot.
4. Place the garment under the foot so that the needle pierces the fabric at the beginning of buttonhole.
5. Lower the buttonhole lever and the presser foot lever.
6. Push the buttonhole lever away from you.
7. Start machine to complete entire buttonhole.

NOTE: When buttonholes are completed, be sure to raise the buttonhole lever as far as it can go.

ADJUSTING STITCH BALANCE

Stitch length differences in forward and reverse stitches of the buttonhole are equalized with the buttonhole stitch adjuster.

If the reverse stitches are too close together, turn the adjuster slightly clockwise using a coin as illustrated; if they are too far apart, turn counter-clockwise.

SATIN STITCH FOOT

Satin stitch foot is grooved to permit dense stitching to pass under it easily.

Closely spaced zig-zag stitches are called satin stitches. This is an attractive stitch used for appliqueing, bar tacking.

Slightly loosen top thread tension for satin stitching. Use a backing of stabilizer or interfacing for the sheer materials to avoid puckering.

Rolled hemming is performed with zigzag stitch, narrow hemming with straight stitch.

Illustration I: Scroll

DOBRADILLO RODILLO

When sewing leather, suede, plastic and velvet, fit the roller foot to aid the smooth flow of fabric. However, especially when sewing softer leather and suede, better results may be achieved by using the normal zigzag foot.

BUTTON SEWING FOOT

Snap on button sewing foot and lower feed dogs. Fix the button in place on the fabric with clear adhesive tape. Align two holes of button with the slot of presser foot, and lower the foot to hold the button securely.

Adjust stitch width to the holes of buttons, and take 5 or 6 stitches. Finish sewing with extra 2" (5 cm) of thread remaining. Draw the threads to reverse side of the fabric and tie. When sewing a flat button, place a needle or a pin between the holes of button as shown.

TWIN NEEDLE (Model 979, 972 only)

A twin-needle produces two rows of parallel stitches for pin tucks, double top stitching and decorative sewing.

When using twin-needles, the stitch width should never be set above twin needle mark, regardless of the stitch you have selected. Doing so will result in broken needles and possible damage to your machine.

THREADING THE TWIN NEEDLE

1. Place a spool on each spool pin. Thread the two threads as one except double thread guides are provided. Draw one thread through each of these and through each needle front to back.
2. Pick up bobbin thread as for single needle sewing. Pull the three threads together under the presser foot to the back of the machine, leaving about 6" (15 cm)clear.

NOTE: Needle threader cannot be used to thread the twin needle.

TURNING A CORNER WITH A TWIN NEEDLE

1. Use hand wheel to stop stitching with the left-hand needle (the longer of the two) just piercing the fabric. Raise presser foot, turn the fabric by 45° and lower the foot.
2. Take one stitch, leaving the left-hand needle piercing the fabric. Raise presser foot, turn fabric by further 45°, lower the foot, and continue sewing.
