The Thread Tension, the Needle Thread take-up, the
Thread
Eyelet are
the
important parts
to
get
the
uniform
stitches. Please see and check the stitch fonn and stitch
tension and then, adjust the parts.
a) The Tension
on
the needle thread should
be
only
sufficient
to
produce
uniform
stitches on
the
under
surface
of
the fabric. The Tension on the looper thread
should
be
just sufficient
to
steady the thread.
b)
Needle Thread Tension and Eyelet Guide
Turn the pulley in the operating direction until the needle
bar
reaches its lowest position. Set
the
needle thread
take-up wire
B so that the distance between its thread
contact
surface
and
the
hole
of
the
needle thread take-up
hole
C is
5mm.
• Check
the
size
of
the
loop
formed
as the needle goes up,
and raise
the
needle thread take-up wire B
if
the
loop is
slDll.ller,
and lower
it
when
the loop is large.
• In
case
DKN-3, Set
the
Eyelet guide so that
the
distance
between the center of
the
screw E and
the
top
of
the
thread eyelet is
22mm.
