1. 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 offwhen 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:
(1) Avoid using the machine at abnormally high temperature (35 OC or higher) or low temperature (5 OC 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 nun 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.
4. 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:
(I) 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 mm adjust
as follows:
(1) 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
"adjusting tool" in the hole B, then remove
the tool.

5. 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.5)
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
lubrication
of the rotating hook as follows:
(1) Turn 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 atrount
is maxinnnn
(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 inachine 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.

1) Cleaning feed dog
Remove the throat plate and clear offthe 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 offthe dust and dirt on oil pump screen.

10. WINDING ADJUSTMENT (Fig.9)
1) 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
deform
2) When the wound thread layer does not present a cylindrical shape
as shown in Fig.9 (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.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.

Note:
Fig. (b): insufficient insertion.
Fig. (c): wrong direction oflong groove.
12. THREADING(Fig.ll)
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.3. To draw the bobb.in 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
