PREFACE
Thank you for your purchase of this sewing machine.
This machine will provide you with excellent performance in sewing from light to heavy material (lawn to
denim). Please refer to this booklet for proper use and optimum service.
Safety Cautions:
Be sure that the etectrical voitage of the socket ©utlet (wail, receptacle) is the same as the rated
smltage of the motor.
o ïJiscoîiîiect ihe power-ime ptug îrom the socket outlet rohen ciiangiag needles, presser idet or
throat pistes, or when ieindiig the machine imattended. This eliminakes the possibilitv of
starting the machine by accidentally pressing the speed coiitroÎIer.
® IJo not piiii the fabric while yon are stitching as this may deflect the needle, causing it to break.
« Before deanliig your maciime, disconnect the powenhiie plug from the socket mitiet,

To run the machine and control the speed, press the speed controller. The harder you press, the faster the
machine will sew. To stop the machine from sewing, remove your foot from the speed controller.
Caytion:
• Be sure that the electrical voltage of the socket outlet (wa!! receptacle! is the same as the rated voltage of
the motor.
® Handle the foot controller with care and avoid dropping it on the floor. Be sure not to place anything
on top of it.
® Disconnect the power-line plug from the socket outlet vvhen changing needles, presses feet or throat
plates, or vtfhen leaving the rnachirie linattended. This eliminates the possibility of startiing the rtiaehine
by accidentally pressing the speed controller.
• Before cleaning your machine, cJiscorinect the power-line plug from the socket outlet.

9 How to thread your machine correctly
Correct sewing cannot be obtained when machine is threaded incorrectly.
Threading is diagrammed on the inner side of the looper cover and identified with colors on the various
thread guides.
(1) Open looper cover. Thread the right looper in the order 0 to (8) as indicated in the figure below,
(threading points marked in orange)

• How to change thread
When you wish to change the needle
thread, left looper thread or right
looper thread with a different thread,
the following steps will make the
changing convenient.
(1) Cut the thread near the spool and
tie the end to the thread you wish
to change to as shown in figure at
right.
(2) Raise presser foot.
(3) Turn the tension dials down
toward the minus (—) sign 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.
Tie knot
Cloth,,
When the machine is completely threaded,
turn the machine pulley toward you 2 or 3
turns while holding the 3 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 scissors.
Page 11
5. Mow to adjust thread tension
Adjust thread tension to suit the type of material and size of the thread used. The thread tension dial
on this machine are a one-tum system and as the number on the thread tension dials increases, the thread
tension become tighter.
® Correct thread tension
Be sure the threads are correctly threaded since otherwise proper thread tension cannot be obtained (See
page 5).

ment can be made easily, adjust the stitch length to
4mm when sewing heavy weight fabrics such as
quilting and to 2mm when sewing light weight
fabrics such as lining fabric, crepe, etc. and you will
obtain excellent seams without puckerings.

1. Fabric, needle and thread
Fabric; Light to medium weight (See page 17)
• Rolled hemming is done by rolling the fabric and overedging (seam width 1.5mm), and is not
suited for heavy or stiff fabrics.
Needle: Singer Cat. No. 2054 (#10), #14.
Thread: A variety of thread combinations can be used for rolled hemming.
2. How to exchange throat plate
o
A throat plate for rolled hem stitching is available
at additional cost. 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.

4. How to sew and cautions
1. Stitch length adjustment (See page 10)
For rolled hemming, set the feed regulator dial to “2” or “F” and a fine seam can be obtained.
2. Sewing
• See page 8, “4. Chain off and test sewing”.
• For rolled hemming, if a slight tension is applied to the material in the sewing direction, a finer seam
finish can be obtained.
• At the start of sewing, slightly pull the end of the chain off so it will not be entangled in the stitch.
• The overedge stitch width for rolled hemming is approximately 1.5mm and cannot be adjusted,
Inthis case, note that the fabric cut width is 3.5mm (adjusted at shipment).
8. Free arm seeving fTyblar work!
This is a free arm machine and is suited for tubular
work.
This is especially convenient for finishing hard-toreach areas such as arm holes and overcasting
cuffs.
Slip tubular work onto the free arm and sew.
Use margin lines on looper cover.
Thick line on extreme right is 5/8 inch from center
of needle.
