• Preparation for operation:
1.
Safety
prec~utions:
1) When turning the power on, keep your hands and fingers away from the area around/under the needle
and
the area around the pulley.
2)
Power must be turned offwhen the machine is not
in
use, or when the operator leaves the seat.
3)
Power must be turned offwhen tilting the machine head, installing
or
removing the
"V"
belt, adjusting
the machine, or when replacing.
4)
Avoid placing fingers, hairs, bars etc. near the pulley,
"V"
belt, bobbin winder pulley, or motor when
the machine
is
in operation.
5)
Do not insert fingers into the thread take-up
cow~.r,
under/around the needle, or pulley when the
machine is in operation.
6)
I'f
a
belt
cover,
finger
guard,
eye
guard
are
installed,
do
not
operate
the
machine
without
these
safety
devices.
2.
Precautions before starting operation:
l ) Never operate the machine before filling the machine's oil pan.
2)
When a new sewing machine is first turned on, verify the rotational direction
of
the pulley with the
pcwer
en.
3)
Verify the voltage and phase (single or three) with those given on the machine nameplate.
3. Precautions for operating conditions:
I ) Avoid using the machine at abnormally high temperatures (
35
·c
or higher) or low temperatures (5
°C
or lower)
2)
Avoid using the machir:e
in
dusty conditions.

• Cautions
on
use
1.
Oiling (1) (Fig.1)
Filling the oil reservoir with oil up to
"H''
mark. Oil level should
be
periodically checked.
If
oil; level is found below "L"; level replenish oil
to
"H"
level.
Use
white
spindle
oil.
2.
Oiling (2) (Fig.2, Fig.3)
When a new sewing machine is used for the first time, or sewing
machine left out
of
use for considerably long time
is
used again,
replenish a suitable amount
of
oil to the portions indicated by arrow
in the below figure.
3. Oiling condition (Fig.3)
See dripping
of
oil through the oil sight hole to check oiling
condition during operation.
4.
Cautions on operation
l ) When the power is turned on or off, keep foot away from
the pedal.
2)
It should be noted that the brake might not work when the
power
is
interrupted or power failure occurs during sewing machine
OQeration.
3)
Since dust in the control box might cause malfunction or
control troubles, be sure to keep the control box cover close during
operation.
4) Do not apply a Multimeter to the control circuit for checking;
------
Otherwise voltage
of
Multimeter might damage semiconductor components in the circuit.
• Operation

Winding
of
bobbin
thread
(Fig.5)
Note: When bobbin thread
is
wound, keep the presser foot lifted.
Adjustment:
Tension
of
wound thread:
Conically wound thread :
Slack winding is recommended for polyester thread and nylon thread.
Move the thread guide toward smaller diameter
of
wound thread layer.
Length
of
wound thread : Loosen the thread length adjusting screw to increase length
of
thread and
tighten the screw to decrease length
of
thread.
3.
Selection
of
thread (Fig.6)
It
is recommended to use
"S"
twist thread in the left needle (viewed from
front), and
"Z'
twist thread
in
the right needle.
When discriminate use
of
needle threads
is
impossible, use
"Z"
twist thread in
both the needles. For bobbin thread,
''S"
twist thread
as
well
as
"Z"
twist thread
can be used.
4.
Threading of needle threads
(1) Pass each needle thread through thread guide A (Fig.7)
Note: When thin slippery thread (polyester Thread
or
filament
thread,
for example)
is
used pass the thread through thread guide
Bas
well.
(2) With the take-up lever located at the upper most position, pass each needle
thread
in
the order shown
in
the following figure (Fig.8).
Note: Pressing the
upper
thread-loosening button shown in
the figure below opens the saucer of the upper thread tension adjuster, and
the upper thread can easily pulled out.

2)
When needle is lifted 2.4mm from the lower dead point, as shown in Figure, the following positional
relationship should be maintained.
The upper edge
of
needle eye should be
2.3111111
below the hook point.
The hook point should be located at the center
of
needle axis.
Gap between the hook point and the side face
of
needle should be
0.

10.
Adjustment offeed dog height (Fig.14)
Height
of
feed dog and pressure
of
presser Foot should be adjusted for individual fabric(s) with the following
cautions:
Fabric will be damaged
if
the feed dog extends too high, or pressure
of
presser foot
is
too large.
Even stitch length cannot be assured
if the feed dog
is
too low or pressure
of
presser foot
is
too small.
Feed dog height should be measured
at the point where the needle
is
at the top
position.
For light fabric: Approx 0.8mm
For usual fabric: Approx l .Onun
For heavy fabric: Approx l.2mm

Relationship between rotating hook motion
and
take-up lever
motion
(Fig.16)
When the timing
belt
(toothed belt) was removed for its
replacement, for example, the relationship between rotating hook
motion and take-up lever motion should be adjusted
as
follows:
1)
Turn the balance wheel and stop when the take-up lever is
lifted
to
its
upper dead point.
2) Lean the machine head backward and make sure the
arrow (timing mark) put
on
the timing belt
is
in line with the black
line on the boss
oflower
shaft bearing.
3)
If
the timing mark
is
not in line with the black line,
remove the timing belt and install it again
to
adjust

13. Safety clutch device (Fig.20.21)
Safety clutch device
is
installed
to
prevent the hook
and
cog belt from damage
in
case the thread
is
caught into the hook when the machine
is
loaded abnormally
during
operatiort.
1)
Function of safety clutch
A.
When the safety clutch acts, the cog belt pulley will be unloaded. Then
the
rotation
of
hook shaft will stop. The
arm
shaft only will rotate. Stop the
operation ofmachine.
B.
Clean the thread thoroughly which
is
caught
into
the
hook.
C.
Tum the cog belt
hub
by hand, and check. Whether the
hook shaft rotates lightly and Properly, place the clutch deice
as
follows.
2)
How to set the safety clutch
A.
While pressing
down
the push button on the opposite
side
of bed by left hand, tum the balance wheel slowly
by
right
hand
away
from
you
as
shown
in
the figure.
White
mark
Law
Shaft
B.
The
balance wheel will stop by the gear plate, but tum the balance wheel more
firmly.
C.
Release
the
push button.
D.
As
shown
in
the
Figure,
the
safety clutch device
is
set.
3)
Force applied to the safety clutch
A.
The force applied
to
the safety clutch
is
the
smallest when the white mark ofthe eccentric pin
faces
the
center of
the
lower shaft.
The
force
proportionally increases
as
the white mark faces the outside.
B.
To
adjust
the
force slide
the
timing belt,
Loosen
the
set
screw,
and
turn
the
eccentric
pin.
C.
After the adjustment,
make
sure
to
fasten
the
setscrew.
14.
Upper
feed
adjustment
(needle side) (Fig.22)
If
the
uneven feeding occurs according
to
the fabric, adjust the
long
hole of the horizontal
feed
shaft crank (right)
to
adjust the
upper
feed
length.
(How to adjust)
l ) Loosen
the
special
bolt.
2)
Move
the special bolt upward
to
decrease upper
feed.
3)
Move
the special bolt downward
to
Increase the upper
feed.
The
upper
feed
and
the
lower
feed
theoretically becomes
equal
at
the
reference line
on
the
horizontal
feed
shaft crank.
4) Securely tighten
the
special bolt after adjustment.

1) Loosen the special bolt.
2)
The vertical strokes
of
the presser feet become maximum when the crank rod
is
moved upward and
3) The vertical strokes become minimum when the nut
is
moved downward and set.
4) After the adjustment,
fully
tighten the special bolt.
The vertical strokes ofthe presser feet can be adjusted within· a range from 6mm to 2mm.
16.
Adjustment
Screwing the pin that connects the link
of
back sewing with the crank
of
back
sewing (down) can adjust
the tolerance
of
between the stitches. Screwing the pin in clockwise can increase the stitch
of
forward sewing;
otherwise, the stitch
of
back sewing will be increased.
