*
When the machine is completely threaded, bring
all of the threads over the throat plate and slightly
to the left under the presser foot.
*
Hold the threads and apply a slight tension.
*
Turn the hand wheel toward you 2 or 3 complete
turns to start the thread chain.
*
Lower presser foot.
*
Continue holding the chain and press on the foot
control until the chain is 5 7.5 cm (2 3 inches)
in length.
*
Place fabric under the front of the presser foot and
sew a test sample.
Note: Do not pull on the fabric while sewing as this
may deflect the needle, causing it to break.
*
At the end of the sample, continue to run the
machine with the presser foot down until the
chain reaches 5 7.5 cm (2 3 inches) in length.
*
Clip the thread chain.
Note: Anytime you have rethreaded the machine
always chain off and sew a test sample to test
tensions and make adjustments as necessary.

STITCH VARIATIONS AND
SEWING TECHNIQUES
• HOW TO SEW A FLATLOCK DECORATIVE
SEAM
*
A flatlock stitch is achieved by adjusting the
tension of the three-thread overlock stitch, sewing
the seam and pulling the fabric apart to flatten the
seam.
*
The flatlock stitch can be used as a construction
and decorative stitch or for ornamentation only.
(1) MachineSetUp
*
Remove the left or right needle.
*
Begin with the machine threaded and tension
balanced for the three-thread overlock stitch (page
21).
*
Loosen the needle thread tension (green or blue)
generously.
*
*
Loosen the upper looper thread tension (orange)
slightly.
Tighten the lower looper thread tension (yellow)
generously.
(2) FatIocking a Seam
*
Place the fabric wrong sides together to sew a
decorative stitch on the right side of the garment.
*
Sew the seam, trimming the excess fabric.
*
The needle thread (green or blue) will form a V on
the underside of the fabric.
*
The lower looper thread will pull into a straight
line at the fabric edge.
29
the
Pull on opposite sides of the seam to pull
stitches flat.
*
(3) Decorative Flatlocking
Place the movable uper knife in the nonworking
position (page 23). The fabric is not trimmed on
this stitch.
*
*
Fold fabric wrong sides together.
Position the fabric so the seam is sewn with part
of the stitch extending off the fabric.
*
Pull on opposite sides of the stitch to flatten.

• HOW TO SEW AN OVER LOCK BLIND HEM
The excess fabric is trimmed and the hem is sewn
and the raw edges are overlocked in one operation.
The overlock blind hem is best suited for sewing knit
wear. It provides a durable finish that is almost
invisible.
Remove the left needle and adjust machine for a
narrow three-thread overlock stitch.
Note: The three-thread flatlock stitch can also be
used.
* Set the stitch length dial at 4
5.
*
*
*
Fold the hem to the wrong side of the fabric, then
back to the right side with 6mm (1/4”) beyond
the fold.
Stitch on the extended hem edge, allowing the
machine needle to barely catch the edge of the
fold
Note: An optional blind hem foot (ULTR HEM
FOOT) is available (page 45)

Turn the fabric and lower the presser foot so that
the knife is positioned in line with the cut edge.
*
Pull slack threads up, then start to sew.

Stop sewing before you reach the corner and fold
the fabric to the left to straighten the corner.
*
*
Continue to sew slowly holding the fabric edge in
a straight line moving the fold as you sew.
*
• PIN PLACEMENT
I.
Insert pins to the left of the presser foot. The pins
will be easy to remove and are away from the cut
ting action of the knives.
Caution: Sewing over pins will damage and/or de
stroy the cutting edge of the knives.
*
• SECURING THE THREAD CHAIN
*
I
*
Thread a large eye, hand sewing needle (such as a
tapestry needle) with the thread chain.
Insert the needle into the end of the seam to
secure thread.

DIFFERENTIAL FEED
(with differential feed machine only)
*
Differential feed is a system which “stretches” or
“gathers” the fabric, when amount of feed of
front feed dog in relation to the rear feed dog is
changed.
*
The differential feed ratio ranges from 1:0.77
1:2.0. Adjustment is made by means of the dif
ferential feed adjusting lever as shown.
*
Feed Control
Lever
Center
Mark
Use of differential feed is very effective in overedging stretch fabrics and fabrics cut on the bias.
(1) Gathered Overedge
(Use regular throat plate)
*
Gathered overedge is most suited for shirring
sleeves, yokes, front and back bodices, skirt hems,
etc. in stretch fabrics such as knits and jersey be

To set the differential feed adjusting lever
*

Note: The setting position of the lever will differ de

amount of feed for shirring.
*
When differential feed adjusting lever is set to
maximum gathering ratio, the stitch length will
automatically change to 3mm (7/64inch) if
previous setting was higher than setting “3”.
*
Be sure to reset the differential feed adjusting lever
to center mark for normal overedge stitching.
J
36
(2) Stretch overedge
(Use regular or rolled hemming throat plate)
*
Stretch overedge is ideal for sewing decorative
collars, sleeves, skirt hems, etc. on loosely knit and
woven fabrics.
To set the differential feed adjusting lever
*
Open looper cover and loosen differential feed
adjusting lever thumb screw.
*
Slide adjusting lever upward above the center
mark, as required, to stretch, and tighten the
thumb screw.
Stretch
Loosen
*
To sew a seam, apply gentle tension to the fabric
by holding the seam lightly in front and back of
the presser foot.
Note: If amount of “stretch” is not correctly set in
relation to the fabric being sewn, the fabric is
apt to shift away from the needle resulting in
improperly sewn overedge seam. In such case,
reset differential feed adjusting lever closer to
the center mark.
*
Be sure to reset the differential feed adjusting lever
to center mark for normal overedge stitching.

HOW TO ADJUST THE PRESSER
FOOT PRESSURE
22.
The presser foot pressure of the machine is pre
adjusted for sewing medium weight fabrics.

Pressure regulating thumb
It may be necessary to adjust the pressure to sew

For light weight fabric—decrease pressure.
For heavy weight fabric—increase pressure.

MACHINE MAINTENANCE
An overlock requires more maintenance than a
conventional machine mainly due to two reasons.
1) A lot of lint is produced due to the cutting
action of the knives.
2) An overlock runs at a very high speed and
needs to be oiled frequently to lubricate the
internal working parts.
*
. CLEANING THE MACHINE
Danger: Before cleaning your machine, disconnect
power line plug from the wall receptacle.
Clean the lint from the looper and knife area often
with a dry lint brush.
