Operation Manual
Adjusting
the
differential
feed
The
differential
feed
prevents
interply
shift.
It
consists
of
two
feed
dogs,
arranged
one
behind
the
other,
which
simultaneously
take
hold
of
the
workpiece
and
move
it.
The
feed
amount
of
either
feed
dog
can
be
set
separately.
It
is
possible
to
have
the
workpiece
moved
more
by
the
front
feed
dog
than
by
the
rear
one,
and
vice
versa.
Due
to
this,
very
good
sewing
results
are
achieved.
Set
the
differential
feed
according
to
the
material
you
wish
to
sew
(see
table
on
page
32).
The
following
settings
are
possible
using
button

The
differential
feed
is
infinitely

to

also
during
sewing.
Note:
The
following
variants
can
be
employed
to
obtain
fashionable

on

feed
setting
of

are
sewn.

is
obtained

a
differential
feed

when

to
heavy
elastic

are
sewn.
