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 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) 1f 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
]0\ver)
(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 nm1 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
(l) Disconnect the plug (12 pins) of cable
fTom 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
111111 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 "adjusting tool"
in the hole 8, 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.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
lubrication
of the rotating hook as follows:
(
1) Tum oil adjusting screw (A) clockwise to
increase oil and
tum 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

Note: nylon or pol.r:;ter thread should be wound with little tension; otherwise. bobbin (D) might break or
defom1.
2) vn;. ~~ ·1 o vound thread layer does not present a cylindrical shape as shown in Fig 9 (a). loosen set screw
(1:5) 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
\\Ound as shmvn in Fig 9 (c). move the bracket leftward.
After adequately positioning the bracket. tighten set
screw (B)
3) Do not overfill the boubin. The optimum length of
thread \Viii fill about 80'% of bobbin capacity This can be
adjusted by adjusting screw (E) of bobbin winder stop
