ADJUSTING
THE OVERDOING WIDTH (STITCH WIDTH AND BAR
TACKING
WIDTH)
AND
OVEREDGING REFERENCE
POSITION
The
needle
swings
from
right
to
left
with
the
right base
line
established
as
the
reference
position.
Perform
the
adjustment
as
follows:
1. To adjust stitch width
©,
screw
in or out
screw
0,
and set pointer 0 to a desired value on scale plate
0.
The actually sewn
stitch
width
will be
the
half of
the
set
scale
value
(mm).
2.
For
adjustment
of
bar tacking width
©,
screw in or
out screw
0,
and set pointer 0 to the value
indicated by scale plate
pointer
0,
making
the
bar
tacking
width
twice
as large as
the
stitch
width.
3. Adjust the position of right base line © by screwing
in or
out
screw 0 so
that
it is
kept
away from
the
cutting
line of
the
knife. As screw 0 is screwed in,
the
right
base
line
moves
to
the
left.
4.
Through
your
trial sewing,
further
perform
fine
adjustment.
5. It is
not
necessary
to
adjust
the
position
of left base
line ® since it remains unchanged when the stitch
width
is
changed.
However,
the
left
base
line
should
be moved to
the
left by screwing in screw 0 if it is
cut
by
the
knife.
