1)
Press down by hand stopper shaft 0 of the needle thread feeder cylinder.
2)
Check the feeding amount of needle thread 9 by needle thread feeder
f)
.
(In
case of 0=31 mm, the remaining amount of needle thread is approximately
18
mm.)
3)
To increase the remaining amount of needle thread, increase the distance of
D.
At
this time, loosen nut 0 and turn
it counterclockwise. To decrease
it,
turn the nut clockwise. When the distance 0 is determined, fix 0 with 0 .
4)
Secure the distance from the top end of needle thread feeder
f)
when it is in the lowest position to top surface 0
of the material in accordance with the thickness of the material.
Incidentally, the height from the top surface of throat plate H is set to
12
mm as standard at the time of delivery
from the factory.
First, loosen two setscrews
0,
adjust installing base 0 by moving it up or down, and set the optional height
H.
Finally, tighten setscrews
0.
In addition, 0 are screws used both for setting the installing base and for fixing the
optional needle cooler.
5)
Next, adjust the whole needle thread feeder unit with four setscrews 0 by moving it up or down since the feeding
amount of needle thread 9 changes by adjusting installing base 0 by moving it up or down.
* Press 0 by hand and check that it smoothly moves up or down
to
perform the up/down adjustment. At this time,
when it does not move smoothly, adjust it with setscrews 0 and
0.
