Safety Cautions;
® Be sure that the electrical voltage of the socket outlet (wall receptacle) is the same as the rated
voltage of the motor.
® Disconnect the power-line plug from the socket outlet when changing needles, presser foot or
throat plate, or when leaving the machine unattended. This eliminates the possibility of start
ing the machine by accidentally pressing the speed controller.
* Do not pull the fabric while you are stitching as this may deflect the needle, causing it to
break.
® Before cleaning your machine, disconnect the power-line plug from the socket outlet.
® Do not attempt to adjust the motor bell. Contact your nearest Service Center should any
adjustment be required.
® Handle the foot controller with care and avoid dropping it on the floor. Be sure not to place
anything on top of it.
® When sewing, closely watch the area being sewn to avoid injuries from needles and knives.
® Use only the handle to lift and move the machine.

the end to the thread you wish to
change to as shown in figure at right.
(2) Raise presser foot.
(3) Note tension reference numbers.
(4) Turn the tension dials down toward
the (—) mark until the dial stops and
draw the thread out so that the tie
knot of the threads extend about
5cm (2 inches) from the presser foot.
When drawing needle thread through
the needle eye, stop the tie knot
before the needle eye, cut the thread
and pass it through the needle eye.
(5) Return tension dials to reference
numbers.

Thread cutter
When the machine is completely threaded,
turn the hand wheel toward you 2 or 3 turns
while holding the 4 threads applying a slight
tension as shown in figure at left.
After chaining off, make a test stitch on a
sample of your fabric so that you can adjust
the thread tensions correctly.
After completing the
seam, chain off approx.
5 cm (2 inches) as
shown in figure at left
and cut thread with the
thread cutter on the
presser foot.

13. How to adjust stitch length
The stitch length dial on this machine is pre-set to 3mm for
normal sewing. Adjust the stitch length to 4mm when sewing
heavyweight fabrics such as quilting and to 2mm when sewing
lightweight fabrics such as lining fabric, crepe, etc. and you
will obtain excellent seams without puckering.
When chainstitchiii”. set stitch lenctli to over 2mni.
4. How to fine-tune overedge seam width
The standard overedge seam width of this machine is 3.5mm when sewing with only the right overedge
needle or 5.2mm when sewing with the left overedge needle. In addition to the widths achieved with
different needle positions, the width may be increased up to a maximum of 7.2mm overedge by use of
the overedge seam width adjustment knob. The width adjustment knob is also handy for fine-tuning the
cutting width for different fabrics and for rolled hemming.
(1) Before making the adjustment, be sure that the power line plug is disconnected from the wall re
ceptacle.
(2) Open the looper cover. (See page 9)
(3) Turn the hand wheel toward you, lower the movable knife as far as it will go and set it in the non
operating position. (See page 11)
(4) Remove the cylinder cover. (See page 9).
(5) Turn the overedge seam width adjustment knob and
with the graduations on the throat plate as a rule,
adjust to desired seam width.
(6) Replace the cylinder cover. (See page 9)
(7) Return the movable knife to its original position and
close the cover.
Note: Do not set the overedge seam width below 3.5mm
as this may cause tlic stationars' knife to interfere
with the throat plate.

5. How to sew rolled hem
Both 1-needle 3-thread and 1-needle 2-thread rolled hem stitching can be performed on this machine.
This machine is also capable of performing standard and right looper thread wrapped 1-needle 3-thread
and standard and left looper thread wrapped 1-needie 2-thread rolled hem stitching.
Rolled hemming can only be performed with the right overedgc needle. Be sure to remove left
overeefoe needle and chainstitch needle.
1. Fabric, needle, thread and stitch length
Fabric: Lightweight fabrics such as lawn, voil, organdy, crepe, etc. perform best.
Rolled hemming is done by rolling and overedging the fabric edge (1.5mm seam width) at the
same time and is not suited for heavy and stiff fabrics.
Needle: Singer Cat. No. 2054 #10.
Thread: A variety of thread combinations can be used for rolled hemming.
Stitch length adjustment (See page 27)
For rolled hemming, set the stitch length dial to “2” or “F” and a fine seam
can be obtained.
2. How to exchange throat plate
A throat plate for rolled hem stitching has been furnished in the accessories for
this machine. By exchanging the ordinary overedge throat plate on the machine
with a rolled hemming throat plate by the following procedure, the machine can
be used for rolled hem stitching.
1.
Disconnect the power line plug from the receptacle.
Turn the hand wheel toward you until the needle is at its
2.
highest point.
3.
Lift the presser foot.
4.
Remove the cylinder cover, (see page 9)
5.
Unscrew the throat plate screw and remove the throat
plate.
Install the rolled hemming throat plate and replace the
6.
screw.
7.
Replace the cylinder cover (See page 9).
Throat plate screw
When replacing the throat plate, be careful that the thread is not
caught between the throat plate and maciiinc.
28
Set seam width to the “M” mark on the rolled hemming throat plate.
To set seam width, align left edge of stationary knilc holder with the
“M” mark on the rolled hemming throat plate.
Be sure the stationary knife is not in contact with the edge of throat
plate.

4. How to sew
Sewing
• Refer to “4. Chain off and test sew” on page 10.
• For rolled hemming, a better stitch quality can be obtained by pulling the fabric lightly in the
forward direction to give slight tension to the fabric.
• When starting to sew, hold chained off thread end lightly to prevent it from being sewn into the
seam.
• The minimum overedge seam width that can be obtained for rolled hem is approximately 1.5mm
because the cutting width can not be set below 3.5mm.
30
Page 33
16. 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 differential
feed adjusting lever pictured below.
Use of differential feed is very effective in overedging
stretch fabrics and fabrics cut on the bias.
• 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 before assembling into garment.
To set the differential feed adjusting lever
• Open looper cover and loosen differential feed adjusting lever thumb screw.
• Slide adjusting lever downward below the center mark, as required, to gather, and tighten the thumb
screw.
Note: Th c selling position of the lever will differ depending on the material being sewn and the amount
of feed for shirring.
When differential feed adjusting lever is set to maximum gathering ratio, the stitch length dial will
automatically move to setting “3” if previous setting was higher than setting “3”.
Be sure to reset the differential feed adjusting lever to center
mark for normal overedge stitching.
Page 34
• 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 (Fig. 1)
To sew a seam, apply gentle tension to the fabric by holding the seam lightly in front and back of the
presser foot. (Fig. 2)
Note: If amount of ’'stretch"’ is not correctly set in relation to the fabric being sewn, the fabric is apt to
shift away from tlie needle resulting in improperly sewn overedge scam. In such case, reset dif
ferential feed adjusting lever closer to the center mark.
Be sure to reset the differential feed adjusting lever to center mark for normal overedge stitching.

17. Free arm sewing (tubular work)
As shown in figure at left, this machine becomes a free
arm machine simply by pushing the convertible bed
plate down.
This is especially convenient for finishing hard-to-reach
areas such as arm holes and overcasting trouser cuffs.
Slip tubular work onto the
free arm and sew.
18. Seam guide lines
The line on the right is 5/8 inch from center of the right
overedge needle. The line on the left is 5/8 inch from the
chainstitch and left overedge needle.
19. Edge guide
Use edge guide for ornamental and blind (overedge) stitching.
Attach edge guide as shown in figure.

Pin tucking is a useful decoration when sewing blouses and children’s clothes. Pin tucking is accomplished
before cutting out garment.
Use ordinary overedge throat plate or rolled hemming throat plate.
Remove left needle.
Before sewing on your garment, always make a test stitch on a sample of your fabric so that you can
adjust the thread tensions correctly for standard 1 needle, 3 thread overedge stitching, or 1 needle 2
thread wrapped edge overlock stitching.
Place movable knife in non-operating position, (see page 11)
Fold fabric in half with the wrong side facing up.
