the
machine
without
fabric
only
if
the
sewing
foot
is
lifted.

Cleaning and oiling
1.
After
a longer
period
of
use
or
standstill
the
sewing machine
must
be cleaned (see also "cleaning
and
oiling"
above).
2. Before oiling, apply a small
amount
of
paraffin
to
the
poinds
indicated.
3.
Operate
the
machine for a
short
while with
the
foot
lifted.
4.
Wipe
off
any
dirt
and
oil
the
machine.
Use
of
fit-on table
In
order
to
be able
to
carry
out
"flat"
work
on
the
Adler
30,
a
fit-on table can
be supplied. This
wooden
table
is
fitted
over
the
lower arm in
front
and
hooked
into
the
lugs provided for
the
purpose
on
the
lower arm. Swing
out
the
table
support
and
in-
sert
into
the
hole
the
stand
plate.
Use
of
the tape binder
1. Unscrew
the
normal
throat
plate.
2. Screw-on
the
throat
plate
63,
fig.
10,
which
is
provided with
tape
guide pins.
3.
Secure
the
tape
guide worm
64
by
the
screw
65
in such a
manner
that
the
throat
plate lug
66
locates
in
the
groove of
the
fastening
pl
ate.
4.
The
front
edge of
the
worm 64
should
be flush with
the
edge
67
of
the
needle hole.
5. Unscrew
the
standard
sewing
foot.
6.
Screw-on
the
special sewing
foot
in such a
manner
that
the
lower
part
situates itself
under
the
throat
plate
trunnion
and
that
the
trunnion
locates itself between
the
guiding pins.
8.
Place
the
tape
reel between
the
disks
and
tighten
the
tension-
ing
nut
so
that
the
tape
is
slightly tensioned.
9. Pass
the
tape
(slightly
taper
the
leading edge)
through
the
pins
68,
through
the
worm
64
and
between
the
upper
and
lower section
of
the
sewing
foot.
10.
Push
the
material
to
be
bound
between
the
worm shoulders
and
thus
between
the
binding
tape,
the
inner edge
of
the
worm
serving as a
stop
to
ensure
an
even infeed of
the
material.
11.
The
tape
width
should
be
adapted
to
the
worm, i.e.
it
must
not
be wider
than
the
worm permits. It is,
therefore,
necessa-
ry
to
use a
different
worm
for
each
tape
width.
