BEFORE STARTING TO SEW
When the machine is plugged in properly and threaded correctly it is ready for sewing. To insure good stitches,
make several sewing tests using the same fabric and thread on which you will sew. Make the proper adjustments
while test sewing.
starting to sew
1. Pull all threads under the prasser foot and toward the back.
(fig.10-A)
2. Lower the presser foot.
3. Tum hand wheel towards you 2 or 3 times and check the
thread chain.
4. Press Foot Control lightly pulling threads towards back and
make thread chain about 5 cm (2 inches).
5. Place a scrap of fabric under the toe of the presser foot at
the position to be stitched. (fig. 10-8)
6. Hold end of thread with your left hand when starting to sew.

thread ends and treat with dot of seam sealant. Let dry and
trim close to knot.
3. For neater finish, pull thread ends back through seam using
hook or yarn needle.
when thread breaks
If the thread breaks while sewing, remove fabric from machine
and rethread as indicated below.
* Upper Looper Thread; turn hand wheel towards you until the
upper looper Is in the lowest position. Pass thread through the
looper hole.
* Lower Looper Thread; cut the needle threads near needles
hole; rathread the lower looper; rethread the neadle/needles.
To begin sewing, place material 3-4 cm (1-2 inches) behind
point where thread broke.

SETTING STITCH LENGTH
The stitch length can be adjusted between 1 and 4 mm.
* For shortest stitch, turn dial to 1, (fig.12-A)
* For longest stitch, turn dial to 4.
As a rule, light weight fabrics take a shorter stitches.
Heavy weight fabrics need longer stitches.
Most normal sewing Is done with stitch length dial set at 3. This
produces a medium length stitch which makes a strong seam and Is
suitable for most fabrics.
ADJUSTING THE DIFFERENTIAL FEED
This machine has two feed dogs - a front feed dog and a rear feed
dog, which move independently and can be adjusted separately.
This Differential Feed prevents waving In stretch fabrics and insures
pucker-free seams in light weight woven fabrics.
The rear feed motion (main feed) is adjusted by turning the
stitch length regulator dial. The front feed motion is adjusted | fig. 12-C
by turning the differential feed regulator dial which is located
inside the stitch length regulator dial. (fig. 12-B)
+ For normal sewing, set the differential feed regulator dial to
“N°. Both feed dogs will move tagether and feed evenly.
+ For pucker-free seams In delicate or closely woven fabrics,
~ turn the dial to “0.7”. The front feed dog motion will be
shorter than the rear feed dog motion. The front feed dog
will hold back the fabric enabling the rear feed dog to take
it up behind the needle without any puckering. (fig. 12-C)
* When sewing stretch or knit fabrics, tum the dial towards
*2". The front feed dog motion will be longer than the rear
feed dog motion and in this manner the fabric can be sewn
without stretching. (fig. 12-D)
The differential feed can be used for gathering or lettuce edging.
* For gathering, set the dial towards “2”, (fig. 12-E)
* For lettuce edging, set the dial towards “0.7”. (fig. 12-F)
SETTING THE SEAM WIDTH
Overedge seam width can be adjusted from 6.2 mm (right
3 АЛИСЕ
ПОДАН
needie 4.0 mm) to 7.2 mm (right needle 6.0 mm) stitch,
Normally the machine is set at 6.2 mm which is the width
most frequently used.
For heavy weight fabrics, set control knob to wider stitch.
1. Tum power switch off,
2. Open front.cover and Free Arm Cover.
3. Push thé Upper Knife Holder to the right and turn the
Seam Width Knob downward 10 select wider stitch width.
For smaller width turn knob in opposite direction.
When adjusting the width, use graduations on throat plate
as guide and line up with left edge of lower knife holder.
The numbers marked on the throat plate are the width to the
right needle, and the distance between needles Is 2.2 mm.
Therefore the width to left needle Is an additional 2.2 mm.
12
ADJUSTING THE PRESSURE ON FABRIC
The pressure on the foot can be adjusted for differant weight fabrics. The
fabric should move along smoothly and evenly without slipping.
Stitches should be uniform in size.
The pressure on this machine Is set for sewing medium weight fabrics.
* For sewing light weight fabrics, decrease the pressure (tum screw to left).
* For heavy weight fabrica, increase the. pressure (turn screw to right).
OVERLOCK SEWING
(1-needle, 3-thread )
This machine can also sew 1-needie, 3-thread overiock
stitching by removing either needle, depanding on the
seam width you desire.
This is the standard overlock stitch and is suitable for most
fabrics.
To convert your machine to a wide 3-thread stitch (7.2 mm
- 6.2 mm), snip the right needle thread just above the aye
of the needle. Remove the thread from the “red” color coded thread guides. Т
Remove the right needle and tighten the right needle clamp screw. This stitch |,

NARROW AND ROLLED HEMMING
By changing the throat plate to “Rolled Hem Throat Plate” and using right needle only, the machine trims fabric,
folds back the edge and sews a narrow hem (overedge). The width of the narrow overedge is 1.5 mm (about
1/16") and is used for overedging light and medium weight fabrics.
Two variations of the rolled overedge hem can be sewn with this machine by changing the thread tension.
Both methods are used with light and medium weight fabrics.
Method B gives a softer finish by pulling the interlocking threads to the wrong side.

The machine comes with a standard overedge throat plate set to the machine.
