CONNECT
THE
CLUTCH LEVER WITH THE
PEDAL
( Fig.2 )
1)
The optimum tilt angle
of
pedal
(A)
is approximately
15
deg.
2) Adjust Clutch
Cover
(
D)
so that Clutch-Lever ( C ) and Draw Bar ( B ) run in line.
3) The balance wheel should rotate counter-clockwise when viewed from the outside
of
Balance Wheel ( G ).
The direction
of
the
motor pulley rotation can be reversed by reversing ( turning
over
180
deg.)
the
power
plug
of
the motor.
4) Adjust the tension
of
V-belt (
F)
by
turning Motor Vertical Position Screw ( E ).
The
proper tension
of
the
V-belt
is
a slack
of
10-20mm when the belt is depressed at the center
of
the belt by finger.
4. PREPARATIONAND LUBRICATION (
Fig.3)
l)
Cleaning the machine
Before
leaving the factory, the machine parts are coated with rust-preventive grease, which may be
hardened and contaminated
by
dust during storage and shipment. This grease must be removed with gasoline.
2)
Examination
Though every machine
is
confirmed
by
strict inspection and test before leaving the factory, the machine
parts may be loose
or
deformed after long distance transportation with
jo
l
t.
A thorough examination must be
performed after cleaning the machine. Turn the balance wheel to see
if
there
is
running obstruction, parts
collision, uneven resistance or abnormal noise.
If
these exist, adjustment must be made accordingly before

run-in operation.
3) Oiling
(1) Required amount
of
oil.
Line ( A ) on the oil reservoir: Max. oil level. Line (
8 )
on the oil reservoir: Min. oil level.
If
oil level
goes down under line ( B ), oil cannot be distributed to each part
of
the machine, thus causing the parts a
seizure.
(2) Replenishing
Always use only No.18 special machine oil for high speed sewing. Be sure to replenish oil to Line ( A )
before sta1iing operation.
(3) Replacing oil
To
replace oil,
remove
Screw ( C ) to drain oil. After completely draining
off
oil, clean the oil reservoir
and securely tighten Screw ( C ), then
fill
the reservoir with fresh oil.

RUN-IN OPERATION ( Fig.
5)
Run-in operation
is
required for a new sewing machine, or a sewing machine left
out
operation for a
considerable length
ohime.
1)
Remove Rubber Plugs ( A ) on the top
of
the arm and replenish sufficient amount
of
oil.
2) Lift Presser
Foot
( B ).
3) Run the machine at a low speed ( 1000-lS00spm ) to check oil distributing condition through Oil
Check Window ( C
).
4) Perform run-in operation at 1000-l SO0spm for 30minutes. After a lapse
of
one month
of
service during
which the working speed
is
increased gradually and the machine runs sufficiently well, the high speed
2000spm can be adopted according to the nature
of
the work.

THREADING (
Fig.7)
To
thread the needle thread, raise needle bar to the upper end
of
its stroke, lead the thread from spool and
perform threading
as
shown
in
Fig.7 .
To
draw the bobbin thread, hold the end
of
the needle thread and turn
the
balance wheel to lower the needle bar and then to lift it to its highest position. Pull the needle thread and the
bobbin thread
is
drawn up. Put the ends
of
needle thread and bobbin thread frontward under presser foot.

1)
The wound bobbin thread should be neat and tight,
if
not, adjust the winding tension by turning
Tension Stt!d Nut
(A)
of
bobbin winder tension bracket.
Note: nylon
or
polyester thread should
be
wound with little tension, otherwise, Bobbin ( D ) might.break
or deform.
2) When the wound thread layer does not present a cylindrical shape
as
shown in Fig.8 (
a)
, loosen Set
Screw ( B )
of
bobbin winder tension bracket and slide Bracket ( C ) leftward or rightward.
If
thread
is
wound
as
shown
in
Fig.8 ( b ), move the bracket rightward, but
if
thread
is
wound as shown in Fig.8 ( c ), move the
bracket leftward.
After adequately positioning the bracket, tighten Set Screw ( B
).
3) Do not overfill the bobbin.
The
optimum length
of
thread will fill about 80%
of
bobbin capacity. This can be
adjusted by Adjusting Screw (
E)
of
bobbin winder stop latch.

ADJUST THE PRESSURE OF PRESSER FOOT (
Fig.10)
Pressure
of
presser foot is to be adjust
in
accordance with thickness
of
materials to be sewn.
First loosen Lock Nut ( A
).
For heavy materials, turn the pressure regulating thumb screw as shown
in
Fig.
IO
( a ) to increase the pressure, while for light materials, turn the pressure regulating thumb screw as
shown in Fig.
IO
(
b)
to decrease the pressure. Then tighten Lock Nut
(A).
The pressure
of
presser foot is recommended to be less
as
long as normal feeding
is
ensured.
12. ADJUST THREAD TENSION ( Fig.11,12 )
In
principle, thread tension
is
to be adjusted
in
accordance with materials, thread and other factors.
In
practice, thread tension is adjusted according to the stitches obtained. The needle thread tension should
-4

be adjusted with reference to the bobbin thread tension. Turn Tension Spring Regulating Screw (
A)
of
bobbin
case clockwise for more tension, or turn the screw counter-clockV{ise for less tension.
It
is common practice to test the bobbin test the bobbin thread tension as shown
in
Fig.12 . Hold the end
of
the thread from delivery eye.
If
the bobbin case is falling slowly, the proper tension
is
obtained. The needle
thread tension can be adjusted by setting ( 1 ) the take-up spring tension. ( 2 ) the thread take-up spring stroke
and ( 3 ) tension spring. All these adjustments will be described
in
the following.

Adjusting the thread take-up spring tension
Loosen Set Screw
(A),
turn Tension Stud (
B)
clockwise to increase the spring tension,
or
turn the stud
counter-clockwise to decrease the spring tension. After the adjustment,
be
sure to tighten Set Screw
(A)
. The
thread take-up spring tension should be about 30g. To Attain this. First loosen Set Screw ( A ), turn Tension
Stud ( B ) counter-clockwise to decrease the tension
of
Thread Take-
up
Spring ( C ) to zero, then turn Tension
Stud (
8)
clockwise until Spring (
C)
comes to the notch
of
thread tension regulating bushing, and again turn
Tension Stud ( B ) halfway back ( counterclockwise ) After the adjustment. Tighten Set Screw
(A).
2) Adjusting the thread take-up spring stroke
Loosen Set Screw ( B ), turn Stud ( C ) clockwise to increase the .stroke
or
turn Stud ( C )
counter-clockwise to decrease the stroke.After the adjustment, tighten Set Screw ( B
).
Before leaving the factory, the thread take-up spring has properly been adjusted. Readjustment
is
needed only
in
the case
of
special material or special thread.

of
the thread guide affects stitch tightness and therefore must be adjusted according to
sewing materials and sewing conditions.
FiglS shows different stitch forms. Normal stitch form should
be

15. TIME NEEDLE TO ROTATING HOOK ( Fig.17,18,19,20 )
A. Adjusting the needle position ( See Fig.17 )
1)
Turn balance wheel by hand to bringNeedle Bar (
C)
to the lowest position
of
its stroke.
2) Remove rubber plug from Face Plate
(A)
.
3) Loosen Set Screw ( B )
of
needle bar adaptor.
4) Move Needle Bar (
C)
vertically to adjust needle timing.
5) After the adjustment, tighten Set Screw ( 8 ) and put

Timing
of
needle motion to rotating
hook
motion has a great effect on sewing performance. The standard
hook point timing ( See Fig.20 )
is
to align Hook Point ( D ) and Needle Centerline ( C ) when Needle
Bar
(
B)
is
lifted by 2.2mm from the lower end
of
its stroke. Besides, Hook Point (
D)
should be 1.0-1 .Smm above
the upper end
of
needle eye ( E
).
When adjusting the hook point timing, also notice that the clearance between the bottom
of
needle notch
and Hook Point (
C)
should be approx. 0.05mm ( See Fig.19 )

Fig.30
In ordinary operation, adjustment
is
not required for the oil pump.
If
oil splashing does
not
occur in the
oil
check
window
when
the machine runs at a low, speed ( approx.2000spm ), reduce the clearance
of
the
by-pass hole.
8 .Adjusting the lubrication
of
rotating hook.
The
lubrication
of
the rotating hook can be adjusted by Oil Adjusting Screw
(A)
as follows:
1) Turn Oil Adjusting Screw ( A ) clockwise to increase oil and turn Oil Adjusting Screw ( A )
counterclockwise to decrease oil.
2) Oil Adjusting
Screw
( A ) adjusts oil amount within 5 turns. When Oil Adjusting
Screw
( A )
is
fully
-9-

tightened, oil amount
is
maximum.
3) Readjustment depends on temperature, sewing speed and the like. In practice,
oil,
amount can
be
judged
as
follows: remove the throat plate and place a piece
of
paper
on
instead, run the machine for about 20 seconds,
then check the oil splashed on the paper.

is
ch~mged
in accordance with the change
of
the needle plate size,
loosen set screw 2, and position the knife so that the blade
of
the needle plate comes
in
