2. Lubrication
Oil is completely drained from the machine in our plant
before shipment. Never
fail to fill oil in the oil reservoir
before starting the machine. The proper procedure
is as
follows (Figure 2 refers):
Remove the plug screw (A), and
fill oil until the indicator
(E)
of oil gauge (B) reaches the mark "F". Use mineral
oil
of 22 to 32 est at 40°C. Example: Tellus oil #22.
Once oiled as above, no oiling is required unless the indi-
cator (E) goes down below the mark "L". Each time the
machine
is to be operated, check the oil level.
To drain oil, remove the plug screw (C), or remove the
cover (563820).
Replace oil after every 2,000 hours
of operation.
A new machine, or a machine
out of service for a certain
period
of time should be oiled as follows:
Remove the cloth plate (D), and oil the moving parts.
Also oil the connecting link and the needle bar. Run the
machine for about
10 minutes at a low speed to ensure
that oil
is distributed throughout the machine. Then
proceed to the normal operation.
The adjustment
of the oil level indicator is as follows
(Figure 3 refers):
Q) Remove the plug screw (C, Figure 2), and tilt the
machine to remove oil. Replace the plug screw.
Q) Place the machine on a level surface.
® Remove the cover (563820) 11t the rear of the
machine, and the rubber bushing (A, Figure 3).
@ Fill oil in the oil reservoir until the oil level is flush
with the bottom line
of the bushing (8, Figure 3).
® Apply a screw driver through the hole of the rubber
bushing, and loosen the screw (C, Figure 3)
of the oil
gauge.
@ Align the gauge (D, Figure 3) to the black line of
"L" mark, and fasten it with the screw (C, Figure 3).
(J) Replace the cover (563820) and the rubber bushing,
and fill oil until the gauge shows the black line
of
the "F" mark.

3. ON SAFETY
a) Alway turn off power supply before threading,
oiling, adjusting, or replacing parts.
b) Wear safety glasses.
c)
Make sure that all the covers and guards are placed
in position before starting the mach.in·e.
d) Keep your hands off the machine while it is in
operation.
4. ADJUSTMENT
4-1
Looper
a) Timing of Looper and Needle
Turn the handwheel counterclockwise (in the direc-
tion of operation), and check the crosswise move-
ment of the looper (B, Figure 4) with regard to the
needle (C, Figure 4). The looper and the needle are
correctly timed if the vertical distance from the
looper point (See Fig. 5) to the needle hole, meas-
ured when the looper point is in line with the left-
side edge of the needle as the looper moves forward
(to the left) is the same as that when measured as
the looper goes back (toward the right) (See Fig. 5).
Deviation of ±0.1 mm is allowable. If the distance
as measured when the looper is moving to the left
is larger than that measured wh.en the looper is
moving back to the right, move back the looper
drive rocker shaft (D, Figure 4), and when it is smal-
ler, move it forward.
-4-
To adjust the position of the looper drive rocker
shaft, first loosen the fastening screw (F, Figure 4)
of the looper drive lever (I, Figure 4). Mount the rod
.146-40 or the screw 22870A on the bell crank shaft
through the thrust adjusting screw (H). Slightly tap
or pull the shaft as required to obtain the required
timing of needle and looper. After the adjustment,
tighten the fastening screw (F).
To adjust the screw (H), loosen both the lock nut (G)
and the adjusting screw (H). First tighten the adjust-
ing screw (H) with 7 kgjcm, and then the lock nut
firmly.

b) Looper Stroke
The center distance between the bell crank stud
and the looper carrier shaft should be I03.2 mm
when the looper
is in the farthest right position,
as shown in Figure 6. Adjustment can be made after
loosening the screw (B)
of the bell crank. After
the adjustment, tighten the screw (B).
c) Adjustment
of Looper and Needle
The distance between the looper point and the needle
center should
be 4 mm when the looper is at the
farthest right position,
as shown in Figure 7. Neces-
sary adjustments are carried
out as follows:
Place a new needle of the specified type and size
in the needle bar as deep as it will go. Tighten the
needle with the needle bar nut. Turn the pulley
until the looper reaches its extreme right-hand posi-
tion. Loosen the nuts (A) and (B), and turn the joint
rod (C) until the required distance
is obtained.
Having adjusted, tighten the nuts
(A) and (B) while
holding the joint rod (C).
Note: Make sure that the front face of the ball
joint, left, (D) is correctly vertical, and is
not in contact with the oil receiver (E) or
other pats after the adjustment.
In the next place, adjust the looper so that the
looper point will lightly touch the needle as it passes
behind the needle. However,
it should never push
the needle. For this adjustment, loosen the screw
(F)
and turn the stop screw (G) as required. Turning it
to the right will make the looper
go away from you,
and turning it to the left will make the iooper get
nearer to you.
After the adjustment, tighten the screw
(F), and
check the movement
of the looper again (Refer to
Figure 8-a).
d) Mounting
of Loop Guide
0
E
Mount the loop guide so that it will lightly contact
the front side
of the needle as the looper moves
forward (Refer to Figure 8-b).

Needle Mounting and Height Adjustment
(Figure 9 refers)
A needle of the specified type and size should be inserted
in the needle bar as deep as it will go. The shaved part of
the needle should face away from you. Tighten the needle
bar
nut (C) firmly so that needle will not come off.
Adjust the height
of the needle bar so that the looper
point
is 0.4 mm above the needle hole when the looper
reaches the left edge
of the needle, as shown in Figure 5.
To adjust, move the needle bar in the vertical direction
after loosening the screw (A)
of the needle bar holder.
When the proper height
is obtained, check the position
of the shaved part of the needle again, and tighten the
screw (A).
Note: If _the direction of the needle is not correct,
the looper will strike against the needle and may
break it. Further, thread break or damage to
thread may also result.

Feed Dog
The feed dog should be centered in the throat plate with
equal clearance
on all sides and ends with the feed travel
set to the desired stitch length (Refer to Figure 10).
At the highest point of travel, tips of the feed dog teeth
should extend 1.2
mm above the throat plate and parallel
to same. The adjustment procedure
is as follows:
a) Vertical Adjustment (Figure
10 refers)
Place the feed dog in the highest position in its travel.
Remove the screw (C) and adjust the feed
dog so
that tips of the feed dog teeth extend 1.2 mm
above the throat plate. Adjust the screw (D) so that
its head will hit the bottom
of the feed dog and sup-
port same from below. Firmly tighten the feed dog
with the
screw (C).
b) Level Adjustment (Figure 11 refers)
Place the feed dog in the highest position in its
travel, loosen the nut (A), and
tum the screw (B)
to adjust the levelness of the feed dog. Turning the
screw to the right will make the leading edge
of the
feed dog raised and turning it to the left makes it
go down. When the required levelness is obtained,
tighten the nut (A) firmly.
c) Adjustment in Longitudinal Direction
(Figure
12 refers).
Loosen the nut (E) and move the feed rocker (C) in
the longitudinal direction. After thll adjustment,
tighten the nut (E).
d) Adjustment in Crosswise Direction (Figure 12 refers)
Loosen the nut (E) and screw (A), and move the feed
rocker (C) in the crosswise direction. After the
adjustment, first tighten the screw (A), and then
confrrm that the feed rod (D) will move freely
before tightening the nut (E) firmly.

4-4 Change of Stitch Length (Figure 13 refers)
Your machine is adjusted to the stitch length of 7 mm
in our plant before shipment. You can change the stitch
length
in the following procedure when necessary:
Loosen the nut (B)
of the feed regulating stud, and turn
the screw (D) on the dial. Turning
it to the right will
make the stitch smaller (S), and turning it to the left
larger (L). Tighten the nut (B) only by half and turn
the pulley by hand to produce a length
of seam to con-
firm whether the desired stitch length is obtained or not.
After the adjustment, tighten the nut (B) firmly.
Note: Nut (B) has left-hand threads.
4-5
Needle Guard (Figure 14 refers)
the upper edge of the needdle hole must be even with
the lower surface
of the needle guard {B) when the
needle (A)
is in the lowest position in .its travel. To adjust,
loosen the screw (C) and move the needle guard (B)
in the vertical direction. Make necessary adjustment
so that the clearance between the needle (A) and the
needle guard (B)
is 0 to 0.1 mm, as shown in Figure 14.
Be careful that the needle (A) will not contact the needle
guard (B).
4-6
Thread Release (Figure 15 refers)
The thread release (B) is mounted on the thread release
base (A), and adjust the amount
of looper thread. Mount
the thread release just in the middle
of the two discs of
thread release cam (F), and secure it in position with the
screw (D). ·
4-7
Thread Tension
Tension on the needle thread should be only sufficient
to produce uniform stitches on the under surface
of the
fabric. Tension on the looper thread should be just
sufficient to steady the thread.
4-8 Presser Bar Height (Figure 9 refers}
Height of the presser bar is set correctly if the needle
bar nut (C) will not contact the presser foot and
if it
is possible to remove the presser foot (D), when the
needle bar is at the lowest position in its travel
and the presser foot lifter lever, located at the far side
of the machine, is fully actuated (pulled to the right).
To achieve the correct setting, adjust the position
of the
presser bar holder {E) so that the clearance between the
lower face
of the presser bar holder and the main body is
8 mm when the presser foot is lying flat on the throat
plate. After the adjustment, confirm
that the presser
foot can be removed
as stated above., and other previous
adjustments.

Presser Foot Pressure (Figure 9 refers)
Adjust the pressure of the presser foot so that the work
is fed uniformly. Turn the presser bar spring adjuster (F)
to the right to increase the pressure, and to the left to
decrease. Too much pressure will result in thread break,
and too weak pressure
is often responsible for unsuccess-
ful chaining on edges of work.

Needle Thread Tension and Guide
(Figure 16 refers)
Turn the pulley in the operating direction until the needle
bar reaches its lowest position. Set the needle thread
· regulator so that the distance between its thread contact
surface and the hole of the needle thread take-up (C) is
4.8 mm. Check the size of the loop formed as the needle
goes up, and raise the needle thread regulator if the loop
is smaller, and lower it when the loop is large.
Set the needle thread guide so that the distance between
the center of the ftxing screw and the thread eyelet is
22mm.
