8) Synchronizing needle and looper (Fig. 5)
^Jrn the handwheel in operating
direction until the point of looper,
moving to the leftCon the back side
of needle), is even with the left side
of the right needle.
Now turn handiheel in the reverse dire- -i
ction so that meeting point is the
same as preceding location.
To adjust, loosen screw E Fig.6
SLIOT^Y just enough to retain its
position tzum handwheel while eccen—.
trie F is being held its position;.
to attiain proper synchronization.
Retigjhten screw Esecurely.
9) Clearance of looper and needle (Fig. 6, 7)
Set the looper and turn handiheel in opera
ting direction until the point of the loo
per, moving to the left (on the back side of
the needle), its clearance is 0-0.1 m/m
(as close as {>ossible without contacting)
To adjust, loo^ screw D Fig. 6 move looper
holder to attain the proper clearance.
Reti^iten screw Dsecurely.

11) Height of feed dog (Fig. 9)
1-1. 2m/ni
When Che needle bar is at the top
of its stroke*, the height of peak of
teeth from the surface of the nee
dle place should be 1.0-1 .*2 m/m.
To adjust, loosen screw A move feed
dog vertically to attain its proper
height.
Retighten screw Asecurely.
12) Changing feed length (Fig. 10)
CAUTION: Whenever feed lengh is changed, besure
to readjust the needle guard.
If the change of feed length is
required, loosen nut A clockwise
turn regulating screw B counter
clockwise to acquire longer sti
tch length,-clockwise acts the
reverse.

^13) Settusg needle guard (Fig.ll)
Set the needle guard horizontally
so that it barely contacts tiie nee
dle vhen at its extreme forward pos
ition.
It should be set vertically as low as
possibley yet have, its top of guarding
surface is 1.0 m/m higher than the poi
nt of the needle, when the point of loo-
per meets needle on its way of leftward
notion.
To adjust, loosen screw A to attain
pro^r position.
Re tighten screw Asecurely.
14) AdjusQnent of looper thread take-up (Fig. 12,13)
a) ^t the looper thread retainer E so that the distance
from its underside to the surface of needle place is
6-7 m/m.
To adjust, loosen screw G nove thread retainer E (a)
vertically to attain its
height. \
Retighten screw G. \
Setting looper thread take-up eyelet
Proper location of thread take-
up eyelet D should be vertica
lly in line with the center of
main shaft.

15) AdjusDnent of rear puller
a) Synchronization to needle bar (Fig. 14)
In upiiT^d motion of needle'bar and
tre po^c of needle is located within
cte thickness of presser foot(1.5 m/m
hi^er than surface of needle plate.), B
puller should start to be effective.
Loosen screw A and secure the location
or eccentric.
Tighten screw Aafter adjustment is
done.
b)
^e arount of travel of the puller (Fis. 15)
Feed length and the amount of travel of
Che puller normally be maintained the same.
To adjust this, loosen nut C, move ball
joint assembly inwardlyC toward upper shaft)
in connecting lever A to acquire more feed
action, outwardly acts the reverse.
Retighten nut C.
c) Fine adjustment of travel of the puller (Fig. 16)
