REGULATION OF
THE WIDTH
OF
THE STITCH.
The
zig-zag
stitch
regulator
controls the
width
of
the
stitch.
By turning
the
knob
clockwise,
you
widen
the
stitch
from
straight
to
a
maximum
zig-zag
width
of
3’l6
of
an
inch;
(This regulator
can
work
during
automatic
sewing
also).
a.
You
also
have
an
additional
numbered
scale
on
the
upper
window. In
ordinary
sewing,
straight
or
zig-zag,
select
the width
desired
as
it
appears
on
the
window.
b.
For special
operation,
such as
sewing
on
buttons.
snaps,
hooks
and eyes,
etc.,
select
the
fine
ad
justment
of
width
required
by
using
the
stitch
width
window.
c. When
a
specific
zig-zag
width
is
required
for
continuous
operation,
use
the
twin
locking
device
below
the
needle
position
lever.
For
example,
when sewing
a
number
of
identical
buttons,
snaps
or
hooks
and
eyes,
locate the
width
of stitch
required,
as
above,
and
lock
in
place
by
loosening
the
stops,
moving
them
toward
the center
until
they
are stopped
and
tightening
them
again.
This
will
prevent
you
from moving
the
zig-zag
stitch
regulator
and
will
lock
the
desired
width
adjustment
in
place.
At
all
other
times,
these
stops
must
be
kept
locked
in
the
normal
position
to
the extreme
right
and
left.
