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. PREPARATION FOR OPERATION
1) 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 jolt. 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.

.'
0 I I I
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 st{itable amount
of
oil to the pmiions indicated by arrow
in
below figure.
CAUTION:
Please
use
white
spindle
oil.
Always
keep
the
presser
foot
lifted
before
attempting
a
dry
run.
4)
Testing
In
order to get the best working situation, run the sewing machine in a low speed for about 1 month after
lubricated fully. Then increase the speed to the need one.
CAUTION:
Before
using
the
following
procedures,
be
sure
to
turn
the
power
switch
off.

WINDING OF BOBBIN THREAD CFig.3)
(
1)
Push the bobbin 3 on the bobbin winder shaft as far as it will go.
(
2)
Bring the thread forward toward the bobbin and wind from below in clockwise direction several times
around the bobbin.
C
3)
Push the lever 5 toward other side so that the driving wheel and driven wheel will engage and then start
the machine.
C
4)
The driven wheel will automatically be free from the driving wheel and stop after the bobbin
is
filled
with thread.
6.
ADJUSTMENT OF THE BOBBIN WINDER CFig.3)
1)
In case
of
uneven winding
If
the thread does not wind evenly on the bobbin, loosen the nut I and move the bracket 2 to the right or to
the left as may be required, then tighten the nut.
2)
Winding amount
of
thread
Loose the screw 6.move adjusting plate 5 towards the axis can decrease the amount
of
thread winding on the
bobbin, and move backwards can increase it.
3)
Winding strength
Strength
of
the winding can be adjusted with the nut

7.
THREADING CFig.4)
Raise the needle bar to its highest position and route the upper thread in the order illustrated beside.

REMOVING AND INSERTING THE BOBBIN
( 1) Removing:
Open
the shuttle race'cap and the bobbin holder, then take
out
the bobbin.
(
2)
Installation: Put the bobbin
in
the rotary hook case, Permit about 5
cm
of
bobbin thread to hand down
freely. Install the bobbin in the bobbin case so that the thread wound direction is clockwise. Then close
the rotary
hook
and the shuttle race cap.
9.
ADJUSTING THE THREAD TENSION CFig.5)
For ordinary stitching, the tension
of
the upper and the lower threads should be equal.
1)
Tension
of
the upper thread
Before adjusting the tension
of
the upper thread, be sure that presser foot is let down. To adjust tension, turn
serrated nut
on
tension device to the right (clockwise) to increase tension and to the left (counter-clockwise)
if
you desire to decrease the tension.
2)
Tension
of
the lower thread
The lower thread tension is controlled by the larger screw near the end
of
the spring at the outside
of
the
bobbin case. Turning this screw to the right (clockwise) will increase the thread tension, while turning
it
to
the left (counter-clockwise) will decrease the tension.

ADIDS1MENT OF STITCH LENGTH AND
FORWARD/BACKWARD
SEWING
(Fig..7)
( 1) Stitch length can be changed by the stitch length adjusting bolt.
(
2)
Stitch length can be adjusted between 0-8mm.
(
3)
Setting the stitch length adjusting bolt upside can sewing ahead, and setting it downside can go
backstitch.

12. FEED
DOG
HEIGHT
CFig.8)
The feed dog should be 1.5mm higher than the vertex
of
the needle plate.
Adjustment
of
the feed dog height can be done as follows:
( 1) Turn the stitch length to the minimum position.
(
2)
Turn the machine balance wheel so as to raise the feed dog to its
highest point.
(
3)
Loosen the screw
of
the feed dog I and adjust the height
of
part 2 by
raising or lowering it. Then tighten the
screwl.

ADJUSTING
THE
HEIGHT
OF
THE
NEEDLE
BAR
Fig.7
When the needle bar
is
at its highest point, normally the measurement between the highest point
of
the
needle plate and the needlepoint
is
28 mm. When this distance need to be adjusted, the steps
is
as follows:
( 1) Take down the face plate, adjust the needle bar to its highest position.
(
2)
Loosen the screw
of
needle bar connecting stud screw.
(
3)
Adjust the needle bar to the right position.
(
4)
Tighten the screw.
14. USING
OF
THE
HAND
WHEEL
CFig.9)
If
you want to change the position
of
the needle when the machine
is
not
running, you can use the hand wheei. fost push the hand wheel in and
