RECOMMENDED
SPEED
1.
Run
new
machine
ata20%
less
speed
than
maximum
for
the
first
4
weeks.
At
the
end
of
4 weeks, original oil
should
be
drained
out
and
replaced.
Thereafter
the
machine
may
be
oper
ated
at
normal
speed.
2. Keep
enough
amount
of
oil in
the
ma
chine;
the
top
of Oil Level Indicator O
should
be
always
between
the
two
lines
of Oil Level Sight Window. See page
12.
3.
While
machine running, OilMonitor©
is
green,
which
shows
the
normal
oil
circulation
inside
the
machine.
If
Oil
Monitor © is red, something ex
traordinary
may
be
caused
in
the
oil
circulation;
check
the
oil
amount
or
Oil Filter. See page
12.
4. Before
starting

or
if

LUBRICATION
The
oil
was
drained
out
from
the
machine
when shipped. Fill Oil Reservoir with
factory supplied oil or equivalent before
operating. Use recommended
type
oil
only.
Keep
the
enough
amount
of
oil in
the
machine;
the
head
of
Oil Level
Indicator
should
be always
between
the
two
lines
'h'
and
'1'
on
Oil Level Sight
Window
O.
Change oil entirely at
the
end of 4 weeks
from starting. After
that,
change oil
every
half
a year.
Lubricating oil
Use Mobil Velocite Oil No.
10
(ISO VG22) or
equivalent.
12
To
fill
oil:
Fig.7
1. Take
out
Screw O and pour fresh oil
into
Oil Reservoir
(QOOc.c.
capacity)
until
the
head
of

Indicator
reaches
the
upper line
'h'
of Oil Level
Sight Window O
2. Re-place ScrewO

NEEDLES
The
type
of
the
factory-set needle is
Organ
DCx27,
Machines can also use
other
similar
needles
to
DC x
27.
This,
however, may require re-adjustments of
Loopers and Needle Guards.
16
REPLACING
NEEDLES
1. Loosen Screw O and
needle.
2.
Insert
a
new
needle
into
the
needle
holeasfar
as it will go.
3. Tighten Screw O after making sure
the
long groove on
the
needle is facing
you.
Note:
When
loosening
or tightening
Screw
O,
be careful
to
use Allen Wrench
properly.
This
is
to
avoid
the
screw
hole
of
Screw
O from damaged.

THREADING
Fig.
13,14,15
Thread
your
machine
correctly
as
shown
in Fig. 13, 14, 15. Incorrect threading
may
cause
thread
breakage, skip
stitches,
or
uneven
stitch
formation.
REGULATING
THREAD
TENSION
Fig.
13,14,15
Changes of threads, seam width, stitch
length, etc, require re-adjustment of
thread
tension.
Adjust individual
thread
tension as
follows:
To
increase
tension:
Turn
Nut
clockwise.
To
decrease
tension:
Turn
Nut
counter-clockwise.

ADJUSTING
DIFFERENTIAL
FEED
RATIO
Fig.
18,19
The
differential
feed
ratio
means
the
ratio
of
the
amount
of
Main Feed Dog's move
ment
to
the
amount
of
Differential
Feed
Dog's movement. When
th^
amount of
Main Feed Dog's movement is bigger than
that
of
Differential Feed
Dog's
move
ment,
the
fabric is
stretched
in stitching.
In reverse,
the
fabricisshrinked.
Adjust
the
differential feed ratio according
to
the
fabrics
and
the
operation.
1. Open Cloth Plate.
Loosen
Nut
O.
2.
Turn
Screw 0 clockwise if necessary
to
stretch
more.
Turn
Screw 0 counter-clockwise if
necessary
to
shrink
more.
3. Tighten Nut O after adjustment. Shut
Cloth
Plate.
Note: 1. Generally,
the
maximum dif
ferential
feed
ratio
is
used
for
convenient
to
represent
the
adjustable
range
of
the
ratio
in
the
machine.
2.
The
1 : 3
ratio
machine
can
shrink
the
fabric
much.
3.
In
the
1 : 2
ratio
machine,
the
ratio
is
approximately
1 : 1
when
the
top
surface
of
Lever
0 is
set
on
the
scale 2 of
Plate
O.
Setting Lever 0 upper than
the
scale
2
makes
the
fabric
stretched;
adjustable
up to
1 :
0.7.

CHAINING
THREAD
It is necessary
to
have a chaining thread
approximately
10mm
long behind
the
presser foot when starting to sew.This will
avoid
"skip-stitches".
After
replacing needles or
thread,
check
thatacontinuous,
smooth
neat
chaining
thread
comes
out
from
under
the
presser
foot.
HOW
TO
CLEAN
YOUR
MACHINE
Cleaning
the
machine
is a
simple
but
important
operation.
It is
not
necessary
to
remove
any
parts.
Merely
release
the
foot
and
swingitout
to
the
left.
Swing
out
the
covers
and
remove
all
the
collected
lint
from
around
the
loopers,
feed
slots,
and
under
the
needle
plate.
Blow
out
any
loose
lint
or
use a
lint
brush.
Re-place
covers and
return
foot
to
the
sewing
position.

DAILY
MAINTENANCE
Before

start
*
Check
oil level is
correctly
maintained
in Oil Level Sight Window.
*
Check
needle
is
correctly
set
and
not
damaged.
*
Check
threadingiscorrect.
*
Check
chaining
threadofapproximately
10mm
long
remains
behind
presser
foot. ^
* Manually lubricate the oil hole for
Needle Holder Guide Stud before
morning
start.
After
close
of
work
* Remove
dust
and lint deposited in
the
machine specially around needle plate
and
looper.
* If any trouble or irregularity is found,
report it to the plant mechanic for
adjustment or repair.
* Keep record showing number of needle
and
thread
breakageaday.
* Dust cover, furnished with machine,
should be placed on
the
