5. Adjusting/~ •
The looper movement of this machine has been properly
adjusted before shipment from the factory, but if it needs re-
adjustment when it is disassembled for repair or etc, prcceed as
follows.
1. Thread Tension (Figure 3)
Thread tension is most important for successful sewing,
Maladjustment results in thread break, skipping stitches and break
of bag.
Proper thread tension may slightly vary with the type of bag and
thread. The norm is given below. Thread tension regulators are
mounted so that the tension is uniform for stitch length. To adjust
the tightness of seam, adjust CD,® in Figure 3.
1) Heavy material (jute,etc.)
Thread tension regulators G) should be loosened slightly (turn
the adjust nut counterclockwise), Needle thread controller ~
after loosening set screw.
2) light material
Tighten thread tension regulators (tum the adjust nut
clockwise).
3) Needle thread
The feed rate of thread must be adjusted according to stitch
length and thickness of bag. If thread tension regulator
adjustment is not sufficient for obtaining the required thread
tightness, use needle thread controller (Z) by moving it up or
down as necessary, after loosening set serew. Thread is tighter
by moving it up (in the direction of the arrow), and is looser by
moving it down. Tighten the set screw after adjustment.
4) Looperthread
Looper thread tension regulator should be adjusted in
accordance with adjustment of the needle thread tension
regulator. Adjust
it so that the looper thread will not sag. If
looper thread tension is too much, the needle thread may break.
2. Presser Foot Pressure
Presser foot pressure must be adjUl>1ed accoo:ling to the material of
bag and thickness. Check the reverse side of seams. The pressure is
too strong if seams show a sign of scratches by feed dog teeth, or
the actual stitch length is shorter than the preset feed rate of feed
dog teeth. In this case, unscrew plate spring adjust screw(I02171),
Figure 4, after loosening nut (5116N2430l). Be sure to tighten the
nut after the adjustment. If the pressure is too weak, seams do not
form a straight line, or the stitch length is irregular. In this case,
increase the pressure by screwing the plate spring adjust screw.
Decrease the pressure when closing jute and other heavy bag
material, and increase it when closing PP woven cloth and other
light bag material. Your machine is adjusted for 3-ply kraft paper
bags at the factory.

3. Looper
a) Tum the pulley in the forward direction and adjust the bell
crank so that the end of the looper is 7mm away from the
needle center when the needle is in the most retracted position,
as shown in (Fig.4). The distance between the nut (outside) of
Looper Connecting Rod must be 38.5 ±O.3mm. (FigA)
Upon completion of the adjustment, tighten the screw of the
bell crank.
b) Check of Height of Needle
Needle 5 and looper I movements are correctly timed if
distance (A and A' ofFigA) between Looper point and Needle
hole when Looper points gets in line with left-side edge of
Needle 5 is the same as Looper 1 passes Needle in forward
and backward movements. A=A'±O.3mm is allowable.
Adjust by hightly tapping the looper Drive Lever. Looper
eyelet should overlap with lower part of oval hole of Needle,
as shown in (Fig.5--c.) as looper goes forward. Adjustment can
also be done by loosening the set screw of the needle bar
connecting stud and adjusting the height ofthe needle bar so
that the end of the needle is 15.5mm from the upper surface of

Adjust the clearance between the needle and the looper
to between O.05-O.1mm when the needle goes forward
and passes the rear of the needle. To obtain the correct
clearance, loosen the screw (fi) of the looper rocker frame
® and incline © the looper rocker. Adjust the clearance
of the needle and looper to between O.l-O.5rnrn when the
looper moves forward to the right at the closest point to

4. Feed Mechanism
a) Ensure that the feed dog does not touch the throat plate as it
passes through. A clearance of L5mm should be seen between
the middle teeth of the front feed dog and the throat plate as
indicated (Fig.S).
b) Height of the Feed Dog
• Adjust the height of the feed dog so that it protrudes 2.5mm
from the upper surface of the throat plate when the feed dog
has risen to the highest position, as shown in (Fig.9). If the feed
dog is higher than this, stitch will not chain satisfactorily, and if
it is lower than this, the stitch width will be too smalL Slacken
nut @with a box spanner to adjust the height of the Feed Dog.
It is important to adjust the height with set screw ® to ensure
that the pressure from the Pressure Foot should not force it
back down. Tighten nut @when the adjustment is correct
• The Rear Feed Dog should be set O. hnm lower than the Front
Feed Dog.
Caution:
Tentatively tighten the nut and make several stitches to be
sure the required stitch length is obtained. After the
confirmation, firmly tighten the nut with a spanner.
c) Stitch Spacing
The stitch width of this machine has been adjusted to lOrnm
before shipment from the factory. The stitch width is
adjustable from 7 to 11.5mm.
(only DS-9C is adjustable from 7 to IO.5mm)
Loosen the nut ® of the feed regulator and move the feed
connecting rod @ in the direction of S, as shown in (FigJO),
to decrease the stitch width. and move the rod in the direction
ofL to increase the width. When moving the feed connecting
rod, do so after confirming that the feed connecting rod can
move freely along the slot in the feed rocker (Rotate the pulley
in the forward direction until the feed dog is in the forefront
position).

c) After the adjustment by steps @ and (b), cut a crepe tape
or thread for test. If the front end of the cutter cuts but the
rear end does not, there is a gap on the rear side. In this
case, loosen the nut @ and loosen the screw
(5) by 1/8
tum, and cut the thread again for test. If it still does not
cut, loosen the screw by another
1/8 tum and repeat this
adjustment and test cut until the thread can
be cut, and
then retighten the nut @. If the rear end of cutter cuts but
the front end does not cut, the adjustment by step @ is
insufficient. Then, make re-adjustment
of the rear side so
that
the gap between both the blades becomes 0.1 to
O.2mm. Here, adjust the upper and lower blades so that
they are in contact with each other on the front side.
If
the lower blade tends to turn away without cutting,
loosen the nut CD and increase the pressure of the spring
by turning the screw @c1ockwise. (Fig.13)
d) Adjust the
overlapped depth of the upper and lower
blades by changing the length of air cylinder rod end so
that the distance between the upper face
of the lower
blade and the rear side

* Plastic contents existent in bag material is melt by the heated needle and may stick to needle, etc., causing
skipping stitches. When closing woven cloth bags, kraft paper bags inclusive of polyethylene coated layer,
polyethylene and PVC bags, etc., dampen needle thread with oil to prevent sticking of plastic contents. Use
silicone oil processed thread for packing rice and other food products.
