• Oil the area through which thread passes, the tension
disc, the thread guide, looper, etc.
(Note:An anticorrosive agent
is applied to the machines
at the factory,
in order to prevent rusting. It is necessary
to use oil to remove this agent. or it may prevent the
thread

All oil has been removed from your machine betbre
shipment.
Fill oil in reservoir betbre starting machine.
• Remove Top Cover (A). ofFig.I, and fill oil to "H" line
of Oil Gauge (B). Use mineral oil of 22 to 32 est kinetic
viscosity at
40°C.
Example: Shell Tellu.s oil #32.
• Once ma.chine is oiled as above, further oiling is not
required unless
oil level goes down below line • L" of Oil
Gauge. Make it a role to check oil level before starting
machine.
• To drain oil, open Cock (C). ofFig.I Replace oil once
every 2,000 hours
of operation.
•
When you have just received a new machine, or if
machine has been stored for some time, sliding parts of
machine may be dry. Following parts should be oiled by
hand with an oiler:
a) Needle Bar Bushing, upper and lower (after removing
upper Face Plate (D)).
b) Feed Llft Bccentric A$s'y (after opening Cloth Plate
(E)).
• Run the machine tbr about 10 minutes at a low speed to
en.sure that oil is distributed throughout the machine.
Then proceed to the normal operation.

Your machine has been properly adjusted before shipment
at our plant. If, however, adjustments are required at your
end due to disusembly, repair, or parts replacement,
obsruve instructions given below.
1 LOOPER
1-1 Check of Looper Travel Distance
Looper (!) travel distence, (A) of Fig.2, should be 25 to
26mm.
To adjust, loosen screw (a) end tum Eccentric Ball (c) of
Looper Bell Crank Connection Rod © cloclcwi.se with a
screw driver, until correct position is obtained.
CAUTION
1. Measure dimension as Looper (D goes around Needle
@.
2. Loosen nut (b) of Fig.2, and align eccentricity of
Eccentric Ball (d) of Looper Connectin1 Rod Aaa'y@
with line (x) connecting centers of Looper Bell Crank @)
shaft and ball mounted.
Keep alignment by tentatively fastening nut (b) during
above a~ustment.
3. For positioning eccentricity of Eccentric Ball (c) of
Looper Bell Crank Connection Rod<Z.), turn Eccenbic Ball
(c).
and find a position where nut (b) is placed Ill the
highest level. Keep this position by tentatively fastenin1
screw (a) during above a~ustment.

To obtain this dimension, loosen nut (b), and tum Eccentric
Ball (d) of Looper Connecting Rod AE.s'y @ clockwise when
dimension (B) is smaller than 5.5mm, and counterclockwise
when it is larger than 5.5mm.
After adjustment, check looper travel distance W and
confirm it is in specified range of 25 to 26mm. Ifnot adjust
Eccentric Ball (c) of Looper Bell Crank Connection Rod ®
again while checking dimension between Needle @ center
and Looper
(D point, until both dimension.
1-3 Check of Height of Needle
Needle ® and looper (D movements are correctly timed
if distance (A and A' of Fig.3) between Looper point and
Needle hole when Looper point gets in line with left-side
edge
of Needle ® is the same as Looper (D passes Needle
in forward and backward movements. A = A'
±0.3mm iB allowable. To adjust loosen screw, (a) ofFig.2,
and tum &centric Ball (c) of Looper Bell Crank
Connection Rod ®
as appropriate. Looper eyelet should
overlap with lower
part of long hole of Needle, as shown in
Fig.4 as Looper goes forward. To adjust, move Needle Bar
@ vertically after loosening screws (a) and (b) of Fig.5 for
Needle Bar Connection @ and Needle Thread
Take-Up(v.
Firmly set screws after adjustment.
CAUTION
1. To facilitate aqjustment, set height of Needle point
above
throat plate @ to 17mm, W of Flg.5, for DN-
2HS, and 18.5mm, (B)
of Rg.5, for DN-2W, with Needle
Bar in its highest position.
2. Confirm proper direction of Needle @ when Needle Bar
@ has been aqjusted (Refer to Fig.13).

1) Needle Size
Available needle size includes DRX2 #25, DNX 11125, etc.
Your
me.chine is provided with DRX2 #25 needle. When
you have changed the needle size, positional adjustment
oflooper must be carried out.
2) A
bent or damaged needle reaults in thread break,
skipping stitches,
l!lld other troubles. Replace it with a
new one in
the steps below. Install a new needle referring
to figures 13 and 14. To remove the needle, tum pulley
by hand until the needle bar reaches its hlghest position.
Tum the needle clamp nut in the arrow mark using the
spanner included in the accessory. You can now remove
the needle from the needle bar. Two important points
must be observed when you install a new needle.
a) The shaved part of the needle must face the leading
cfuection ofthe machine (Fig.13).
b) Push the needle in the needle b8l' 88 deep 88 it will go,
c) When you have installed the needle, tighten the needle
clamp nut Jinnly.
d) For DN-2W install needles in the needle holder, and
secure them with screws.
