PRECAUTIONS BEFORE STARTING OPERATION
1)
Safety Precautions:
(1) When turning the power on, keep your hands and fingers away from the area around/under the needle
and the area around the balance wheel.
(2) Power must
be
turned
off
when the machine
is
not in use, or when the operator leaves the seat.
(3) Power must
be
turned
off
when 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 balance wheel,
"V"
belt, bobbin winder balance wheel,
or motor when the machine is in operation.
(5) Do not insert fingers into the thread take-up cover, under/around the needle, or balance wheel when the
machine
is
in operation.
(6)
If
a belt cover, finger guard, eye guard are installed, do not operate the machine without these safety
devices.
2) Precautions before Starting Operation:
(1)
If
the machine's oil
pan
has an oil sump, never operate the machine before filling
it.
(2)
If
the machine is lubricated by a drop oiler, never operate the machine before lubricating.
(3) When a new sewing machine
is
first turned on, verify the rotational direction
of
the balance wheel with
the power
on.
(The balance wheel should rotate counter-clockwise when viewed from the balance
wheel)
(
4)
Verify the voltage and (single or three) phase with those. given on the machine nameplate.
3) Precautions for Operating Conditions:
(I)
Avoid using the machine at abnormally high temperature (35
'C
or higher) or low temperature (5
'C
or
lower)
(2) Avoid using the machine in dusty conditions.

3. INSTALLING THE BELT
(Fig.l)
1)
Use
a V-belt
for
sewing machine use, type M
2)
To
adjust the belt tension, change the motor
height by turning the tension adjust nuts so that the
belt sinks about
15
mrn when depressed
by
hand at
the
center
of
the belt span.
If
the tension is too
low,
the
speed may not be consistent in the low or
medium range, or the needle may not stop in the
proper position.
If
the tension
is
too high, the motor
bearings will deteriorate more rapidly.

ADJUSTMENT OF NEEDLE
BAR STOP POSITION (Fig. 2, 3)
1)
Adjusting
of
"Up"
position
When the pedal
is
kicked down
by
heel, the
machine stops at "UP" position.
If
the marks
deviate larger than 3 mm adjust
as
follows:
(
1)
Disconnect the plug (
12
pins)
of
cable
from the machine head.
(2)
Run the machine and stop at "UP"
position.
(3)
While holding the balance wheel insert
the
"adjusting tool" in the hole
A,
then
remove the
tool.
2) Adjusting
of
"DOWN" position
Set the machine stops at "DOWN" position.
When the pedal is kicked down
by
hell, the
machine stops
as
"DOWN" position.
If
the marks
deviate larger than 3
nrrn
adjust
as
follows:
(I)
Disconnect the plug (12 pins)
of
cable
from the machine head.
(2)
Run the machine and stop at "DOWN"
position.
(3)
While holding the balance wheel insert
the

LUBRICATION
(Fig.4)
Pour oil up
to
position A
of
the oil tank.
During operation, check the oil level periodically,
and
in
cases where the oil level is
below
position B
replenish the
oil
supply up to position
A.
Use white spindle oil.
6.
CONDITION
OF
OIL
LUBRICATION
(Fig.S)
While operating the machine, check the
condition
of
oil lubrication
through
the oil check
window.
7.
LUBRICATION
ADJUSTMENT
(Fig.6)
Adjusting the lubrication
of
rotating
hook
Oil adjusting screw (A) can adjust the
_]ubrication
of
the rotating hook as follows:
(1)
Tum
oil adjusting screw (A) clockwise to
increase oil
and
turn
oil adjusting screw (A)
counter-clockwise
to
decrease oil.
(2) Oil adjusting screw (A) adjusts oil amount
within 5 turns. When oil adjusting screw (A) is fully
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.
8.
ADJUSTMENT
OF
OIL
PUMP
(Fig.7)
The standard adjustment is as follows: The
adjusting plate keeps the bypass hole fully closed.
To
decrease splashing, open the bypass hole
appropriately

REGULAR CLEANING (Fig.8)
1)
Cleaning feed dog
Remove the throat plate and clear
off
the dust and lint between feed dog tooth slots.
2) Cleaning rotating hook
Swing out the machine
head
and clean the hook. Wipe the bobbin case with soft cloth.
3) Cleaning oil pump, screen
Swing out the machine head and clear
off
the dust and dirt on oil pmnp screen.

10. WINDINGADJUSTMENT (Fig.9)
I) The wound bobbin thread should
be
neat and tight,
if
not, adjust the winding tension
by
turning tension
stud nut (A)
ofbobbin
winder tension bracket.
Note: nylon or polyester thread should
be
wound with little tension; otherwise,
bobbin
(D) might break or
defonn
2) When the wound thread layer does not present a cylindrical shape as shown
in
Fig.9 (a), lo,osen set screw
(B)
of
bobbin winder tension
bracket
and slide bracket (C) leftward or rightward.
If
thread is wound
as
shown
in
Fig.9 (b), move the bracket rightward,
but
if
thread is
wound
as
shown in Fig.9 (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.

necessary, adjust the inclination
according
to
the material
to
be
sewn
as
follows:
1)

See the illustration. The standard distances from
the needle center are 6.5 nun and 3.3 mm from
the movable knife (left) and fixed blade
respectively.
(2) Adjustment
of
knife engagement. With the
solenoid activated,
tum
on the machine. This
rotates the thread trimming cam which rotates the
movable knife (left). When the movable knife
(left) has moved to its farthest distance, the
standard engagement
of
the blade is 1.5-2.0 tmn.
(3) Adjustment
of
knife engaging pressure.
If
a
thread is poorly cut, particularly when it is thick,
slightly increase the engaging pressure. This
should solve the problem. The engaging pressure
can be adjusted in tllis way: Loosen lock nut
B,
and adjust it
by
using adjusting screw A
