t GENERAL DESCRIPTION
1. Special features
This is a high speed industrial sewing machine for embroidering. With
a speed of I,
700 stitches per minute, it can produce a width of throw of
12m/m (15/32'') but
if the machine i:; used at IOm/m (25/64") width of
throw, it can embroider at a fast speed
of 2,000 stitches per minute.
This machine can, not only embroider designs on light weight
or heavy
weight materials, but it can also embroider names and all kinds of marks to
produce attractive and inviting embroidered work.
The design of this machine is of beautiful two-color tone and as the
lubrication is of a centralized system, it is not necessary to oil the parts
at each instance. Also, as the presser
bar is of joint rod system, it is not
to push
the presser bar up or down when installing an attachment.

As previously mentioned, the speed of this machine
at the maximum
zigzag width of throw of 12m/m (15/32")
is 1700 stitches per minute and
when the zigzag width is less than lOm/m (25/64"), it can embroider at the
speed of 2,000 stitches per minute.
4. Installing the machine
(A) Correct height
Install the machine on the table and shake the machine a little to see
if it's
balanced evenly. When all the corners are even it should not move
but if any one of
the corners is uneven, it will rattle.
When it rattles, nail in a thin felt cushion pad (four of which are in the
accessories box together with nails), under the low corner and make the
height even. Be sure to nail in the head of the nail deep inside the pad
untii it sinks into it.
Unless the height of the machine is installed evenly and balanced,
it will not rotate quietly.
(B) Main Drive
Belt
The machine is connected to the drive motor by a composite drive belt:
( 1 ) Be sure you are using the correct width belt
(
2) Be sure both pulleys are lined up so the belt is not twisted or angled.
This would cause the machine to run noisily and subject it to unnecessary wear.
( 3 ) Set the tension nice and snug but not extremely tight as to put undo pressure
on the machine and motor
If an old-style leather belt is used, observe the following:
( 1 ) Should not
be too tight. At first, the leather belt is very stiff, so often
it
is liable to be too tight. When it's too tight, the machine will vibrate.
(
2) Joining of the belt. Normally, the belt is joined with a wire.
When the joining is out of alignment or when the wire is sticking out, the
machine cannot be
run smoothly.

5. Bobbin winder spool pin
For the convenience of packing, the needle thread guide pin and the
bobbin winder spool pin are removed from the machine
and packed sepa-
ratery in a vinyl bag.
The needle thread guide pin can be lightly tapped in and inserted. To
install the bobbin winder spool pin, remove the top cover of ·the machine.
Just loosen the screw at the top of the cover and it will come off. Then
insert the bobbin winder spool pin from front, plug in the nut from rear
and tighten it with a wrench. (Fig 4)

II. HOW TO OPERATE THE MACHINE
l. Lubrication
Lubricate the oil holes marked in red with Oil! to 2\drops every day
(Fig. 5). But to the holes CD ® @ @ @ marked with heavy red mark.
lubricute about 5 to 6 drops every day. There are oil reservoirs on
these holes and from here all
the essential parts are supplied
Fig. 6 Oiling spots of rotary hook
2 Oiling the rotary hook
Every day drop I or 2 drops of oil to the hook groove of the rotary
hook shown by the arrow in Fig.
6. This oil soaks through the felt which
is inside the hook and lubricates all the essential part:; of the rotary hook.
3. Needles
Select the needles according to the embroidering material and the
needle thread. (Refer to Table).
In setting
the needle, be sure that the carved part is on the other side
and the groved part of the needle
is facing the operator. (Fig. 7)

5. Winding the bobbin thread
As the wound condition of the bobbin thread greatly affects
the
&ewing condition, be very careful on the amount wound,
the method
of winding and the tightness of the wound thread.
First, insert the bobbin deep into the bobbin winder shaft as
far it goes (Fig. 9\. Pull out the thread from the thread spool,
pass it through
the eyelet of the thread tension base, wind it from
the opposite side of the 2 tension discs towards you (Fig. 10),
and wind it 3-4 times around the bobbin from under (Fig. 11).
If the trip latch is pressed down with your thumb the bobbin
winder will contact the belt
(fig. 12).
When the machine is rotated, and sufficient amount of thread
is wound around the bobbin,
the trip latch will be relt!ased
and the winding is finished.

6. Inserting the bobbin into the bobbin case
Hold the wound bobbin between your thumb and forefinger of your
right hand and, with the thread hanging down, insert it into the bobbin
case.
Next, pass the thread which is sticking out through the groove of
the bobbin case, duck it under the thread tension spring of the bobbin case
while pulling it, and finally pass it through the wire of the thread guide.

7. Fixing the zigzag width of throw
The zigzag width of throw of this embroidering machine can be regu-
lated by the knee press as shown in Fig. 14. From your sitting position,
make certain that the knee press smoothly contacts the tip of your right
knee (Fig. 15).
If your knee is not correctly contacting the knee lifter, adjust it by
loosening
the screw ® Fig. 14.
Action of the knee press
Rotate the machine slowly and if the knee press is
pressed with your knee, the needle will vibrate right to left
and the embroidering can proceed.
The more the knee press is pressed with your knee,
the greater becomes the zigzag width of throw. (Fig. 16)

8. Embroidering with a fixed zigzag width of throw
When you want to embroider with a definite, fixed zigz11g width of
throw, loosen
the zigzag width regulating knob, pull the lever at the right
of the knob, set the graduator at the width desired by moving the graduator
with your knee and tighten the knob.
This will set the graduator at the
fixed width, so you can do a fixed width embroidering job without moving
your knee. (Fig. I
7)
9. How to set up the embroidering hoop
It will be necessary to do all kinds of embroidering with various zigzag
width of throw. So,
in each instance, loosen the zigzag regulating knob and
adjust the width to your liking.
Before starting the embroidering, the cloth must be stretched into the
hoop.
The stretched cloth inside the hoop should not be too loose or too
tight
but should be just right all around. If it's too loose, it might invite
skip-stitching
but if it's too taut on a light weight materials, the cloth might
rip. So in such a case, attach a heavy cloth around the hoop together with
the light weight material
and pull this heavy weight material with the stret·
ched light weight material.
10 How to embroider
Press down the cloth inside the hoop with your two hands and by set-
ting the zigzag width with your knee, start embroidering. Be careful not
to press down on the cloth too much but just enongh to keep it down be·
cause if too much pressure is applied on your two hands, you cannot do a
good embroidering job. Your knee action must harmonize with the move-
ment of your hands to produce a flawless embroidering work.

11 The thread tension
The upper thread tension and bobbin thread tension of this machine
can be set independently of each other.
The upper thread tension can be
adjusted
by the tension nut (Fig. 20) and the bobbin thread tension can be
adjusted
by the bobbin case thread tension screw !Fig. 1:31. Normally, the
thread tension of the bobbin thread inside the bobbin case should be set and
then the upper thread tension
is fixed by the thread tension nut to obtain
ideal tension. In
an embroidering work, the thread tension should be adjust-
ed so that the upper thread should come out on the back of the cloth, a
stitching process quite different than conventional stitching.
As shown
in Fig. 21, it is considered to be ideal for the sewing width
of the bobbin thread to be about
1/3 of the entire zigzag width. Try to
leave the thread tension nut a little loose to obtain an ideal thread tension.

12. When the thread breaks
The embroidering thread
is a fine thread, and even though it does not break on a fine, crisp
day
... on a rainy day or when the air is damp or when the humidity of the working compound is high,
the breakage percentage may increase.
Besides these adverse conditions, the thread might break when the machine is set up correctly.
Following are some
of the potential problems:
A) The needle thread may be incorrectly threaded. A loop or guide may have been missed or it is
caught on something.
B) The needle thread is not feeding properly from the thread spindle. (It may have slipped below
and is wound around the thread spindle.)
C) The bobbin thread is broken or used up.
D) The rotary hook is installed wrong.
(When an especially large size
of needle is used, match the sewing hook to corresponding size.
Refer to Chapter III-3 on "Timing the sewing hook with the needle)
E) The needle thread tension is too tight and the thread can't take the pull.
F) The needle has become bent and is not lining up with the hook and bobbin correctly.
G) The deflector point of the sewing hook is damaged.
(The damage may sometimes be smoothed out using a very fine
sandpaper- 400 or higher.)

Ut ADJUSTMENT OF STITCHING
1. Timing and adjustment of needle throw
As shown in Fig. 22, when the height of the right and left motion of the needle throw
at the start of the_ throw and at the end of the throw is not same, the needle might "skip''
because the needle throw movement is not ended even though the needle is piercing the
cloth.
Thus, the needle will tear the cloth and attractive sewn product cannot. be obtained.
To obtain correct timing and adjustment of needle throwing, first remove the arm cover, loosen
the set screw of the main shaft gear screw slightly,
and as you watch the needle stitching,
rotate the gear slightly and set the timing. After adjusting, be sure to tighten
the set screw firmly.

2. Adjusting the correct position of the neecile throw
The correct stitching of the needle throw is when the needle stitches
evenly
to the hole of the throat plate, not too much to the right or left, as
it completes the throwing motion. (See © Fig. 23.

Fig. 23
The correct position of the needle throw is already set at the
factory.
It should need no adjusting. In case it has been thrown off...
To obtain the correct needle throwing position, remove
the
arm cover, loosen the set screw of the zigzag adjusting
shaft bushing, and with a large spanner, rotate
the flat part
of the bushing which came outside and throw the needle to
right or left as you rotate the hand wheel. Also, by setting
it at 0 and by inserting a piece of paper and confirming the
correct needle stitching position
by watching the holes in
the paper, adjust
the needle throwing position. After the
adjustment, firmly tighten the set screw and cover up the
arm cover.
If the needle does not stitch into the center of the throat
plate groove at the 0 position, remove the face plate, loosen
the eccentric shaft set screw
and as you rotate the eccentric
shaft (Fig.
25 CD) with a screw driver, adjust the correct
needle stitching position.
