Operation Manual

With
the
stitch
length
key
(125),
the
buttonhole
seams
can
be
set
more
densely
or
loosely.
Buttonholes
with
gimp
thread
In
the
case
of
elastic
materials,
it
is possible
that
the
button
holes
extend.
Therefore,
the
button
hole
strip
should
be
strengthened
with
interlining
material.
In order to
retain
the
shape
of
the
button
hole,
use
gimp
thread
if possible.
Place
the
gimp
thread
over
the
back
ridge
“A”,
pull
taut
and
jam
it
into
front
ridge
“B”
to
the
left
and
right
(Fig.
1).
(Pull
runner
fully
forwards).
The
buttonhole
sequence
is
the
same
as
without
gimp
thread,
see
page
102.
After
completing
the
buttonhole
pull
on
both
thread
ends
of
the
gimp
thread
(Fig.
2),
until
the
loop
is covered
up
by
the
bar.
This
is
where
the
button
is
located
later.
Pull
the
gimp
threads
through
to
the
underside
with
a
needle,
secure
them
and
trim
them.
We
recommend
to
determine
the
second
scans
bar
yourself
for
this
type
of
buttonhole
(see
page
102).
Single
buttonhole
As
you
know,
it
is
difficult to
sew
buttonholes
in
collar
stands,
waistband
strips
etc.
In
such
cases,
the
buttonhole
length
should be
drawn
in
pre
viously
and
the
first
seam,
bartack
and
second
seam
controlled
by
hand.
Sewing
foot
No.
2
can
also
be
used
for
this
work.
(Sewing
procedure
as
described
on
page
102).
