Determining
the
bartack
(semi-automatic)
If
you
wish to
determine
the
bartack
in
a
pro
grammed
buttonhole,
press
“tie-off/buttonhole’
key
19
(Fig.

A
dash
flashes
in
display
21
at
the
right
side
of
program
92a,
b,
or
c
(Fig.
4).
The
machine
now
sews slowly
just
before
the
end
of
the
second
seam.
When
both
seams
are
the
same
length,
press
key
19
again.
The
bartack
is
now
sewn
and
tied
off.
If you
wish
to
sew
the
next
buttonhole
fully
auto
matically,
press
key
19
again.
(Sewing
sequence
as
described
on
page
90).
The
flashing
dash
will
then
have
disappeared.
Note:
If
you
interrupt
sewing
at
the
reduced
sewing
speed
by
releasing
the
foot
control,
the
machine
will return
to
the
normal
speed
when
you
start
sewing
again.
When
you
are
working
in
the
bartack
determining
mode
and
have
selected
bartack
design
“a”,
you
have to
press
the
“tie-off/buttonhole”
key
when
the
second
buttonhole
seam
has
reached
the
second
to
last
mark of
the
buttonhole
foot.
Obser
vance
of
this
always
ensures
correct
finishing
of
the
bartack.
Adapting
the
buttonhole
seam
length
A
garment
may
consist
of
different
numbers
of
fabric
plies,
e.g.
the
buttonhole
strip
may
consist
of
three
plies
and
the
collar stand
of
six
— owing
to
the
folded
seam
edge.
In
this
case
it
is
necessary
to
program
the
buttonhole
for
varying
numbers
of
fabric
plies in
order
to
maintain
the
same
button
hole length
as
on
the
three-ply
buttonhole
strip.
Note:
For
sewing
buttonholes
on
knitted
or
very thin
materials
we
recommend
