adjusted
before
shiprnent
from the
factory,
but
if it
needs
re-adjustment
when
it is disassembled
for repair
or
etc,
prcceed
as
foilows.
1. Thread
Tension
(figure
3)
Thread tension
is
most important
for successful
sewing,
Maiadjustment
results
in thread
break,
skipping
stitches
and
break
ofbag.
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
O,@
in
Figure
3:*
1) Heavy
material
fiute,etc.)
Thread tension
regulators
O
should
be loosened slightly
(turn
the
adjust
nut counterclockwise),
Needle thread
controller
@
after
loosening
set screw.
2)
Lisht material
Tighten
thread
tension
regulators
O
(turn
the adjust
nut
clockwise).
3) Needle
thread
At
the shipment,
the
needle
thread
controller
@
for
Creped
Paper
Tape is
adjusted
a iittle
downward.
In case
of using
sewing
machine
without
Creped
paper
Tape, the
needle
thread
controller
@
should
be re-adjusted
upward.
The feed
rate
of
thread
must
be adjusted
according
to
stitch
leneth
and
thickness
of bag.
If thread
tension
regulator
adjustment
is
not
sufficient
for
obtaining
the
required
thread
tightness,
use
needle
thread
controller
@
by moving
it
up
or down
as
necessary,
after
loosening
set
screw.
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)
Looper
thread
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.lf
looper
thread
tension
is too
much,
the
needle
thread
may
break.
2- Presser
Foot
Pressure
Presser
foot
pressure
must
be
adjusted
according
to
the
material
of bag
and
thickness.
Check the
reverse
side
o{
searns.
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(102171),Figure
4,
after
loosening
nut
(5/16N24301).
Be sure
to tighten
the
nut
after
the
adjustment.
If the
pressure
is
too weak,
seams
do
not
form
a straight
line,
or
the
stiteh
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

To facilitate the adjustment
first adjust the looper avoid

so that its
screw is 45" to center of the
main shaft.(Fie.7-b)

4. Feed
Mechanism
a)Clearance between Throat Plate and
Feed Dog
Ensure that
the feed
dog
does not touch
the
throat
plate
as it
passes
through. A clearance of
1.5mm
should
be seen
between the middle teeth
of the front feed dog and the
throat
plate
as
indicated
(p'k.A).
b)Height of the Feed Dog
o
Adjust
the
height
of the feed dog so that it
protrudes
2.5mm from
the upper surface ofthe throat
plate
when the
feed
dog
has risen
to the
highest
position,
as
shown
in
(p'ig.g).
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 smal1. 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.
o
The
Rear Feed
Dog should
be
set 0.1mm lower than the
Front
Feed Dog.
Gaution:
Tentatively tishten 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.

(DS-9A)
The
knives,
(A)
and
(B)
are to
be adjusted
as following
steps.
a)
pix
the
knife
(A)
with
tightening
scre\4r
@
at the
proper
position.
Be
sure that
the knife
edge
does not
protrude
from
thread
gutter
ofthroat
Plate.
b)
Fix
the knife
(B)
in
the
gutter
ofknife
lever,
bv
tentativelv
tightening
screw
@.
c) Tum
pulley
clockwise
direction.
When
the knife
(B)
moves
farthest
right
position,
fix
the knife
(B)
moves
so that
it
contact
with
the
edge
of
knife
L\)
approx,
2mm.
d) Sliehtly
bend
knife
lever
to obtain
proper
contact
between
knife
(A)
and
(D.
e)
Tr:nto
cut
several
threads wound
and then confirm
ifthey
are cut
sharply and
straightly.
6. Cutter
(DS-9C)
a) To
occlude
the upper and
lower blades, manually
move
the
upper
blade. To
do so,
put
off air
source. Here,
prior
to
lowering
the upper blade,
loosen the
screws
@,@
and
@
andthenuts
@
and
@
shownh(fie.tf).
When
both blades
are oecluded,
allow
a
gap
of
0.1 to
0.2mm between
the faces of the
two blades on the
rear
side, andtighten
the
screw
@
and the nut
@.
b) After
the
setting
described
in
O
above,
where the
screw
@
is
in light contact
with the screw
@,
tighten the
nut
@.

NOTE:
The
gap
a{ustment
can be
easily made
placing
a
sheet of
Kraft,
paper
between
the
upper and lower
blades, as shown
in
(Fig.14).

c) After the adjustment by steps
@
and
@,
cut a crepe
tape or thread for
test.
Ifthe
front
end
ofthe 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
@
by l/8 turn, and
cut
the thread
again for test. If it still
does
not
cut,
loosen the screw by another 1/8
turn 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 insufrcient. Then, make
re-adjustment of
the rear side so that the
gap
between both the blades
becomes 0.1 to 0.2mm. 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,
lsesen
the
nut
@
and increase the
pressure
of
the spring by turning
the screw @ clockwise.
(p'is.t3)
a) eajust the
overlapped
depth ofthe upper and lower blades
by changing the leneth ofair cylinder
rod end so that
the
distance between the upper face ofthe lower blade and
the
rear side of the upper blade becomes 2mm, as shown
in
(Pis.t+).
e) Do not operate without Air Speed Controller
on the
Solenoid Valve
of
the
Stand.
(See
the Parts List
A2/A6(2L)
pace
12 Ref.No.49). In case of operating
the
Solenoid Valve
without air
Speed Controller, it will be the
causation
for some
parts
broken.
0
eajust air
pressure
to 0.4Mpa
(ake/cfi)
not to exeeed
0.5Mpa(5kg/crf,).
in case of using with excessive
air
pressure
(over
0.5Mpa(5Kc/crfi)),
it
will
be the
causation
for some
troubles.
