Setting
the
Length of
Stitch
The
stitch length
is
regulated by moving the
stitch
regu.
lator
lever
up
or
down
and
can be
limited
for
forward
and
reverse
sewing by
tightening
thumb
nut S çFig.
2).

The
numerals
on
the
left
of
the
stitch
reguloor scale
indicate
the
length
of
stitch in millimeters
(rangina
from
5 to
25
stitches
per
inch).
When
moving
the
stitch
regulator
lever
up
beyond
the
zero
mark,
the
machine
will
sew
forward.
For
back-
tacking,
the stitch
regulator
lever
is
to
be
set on
R
(for
reverse).
The
stitch
length
may
be
regulated
when sewing.
When
the stitch
regulator
lever is set
at
zero,
the
machine
will
not
feed
at
cli.
This
position is used
for
embroider
ng
and
darning.
Reverse
feeding
should
be used
only
for
tying
off
the
end
of a
seam
(bocktacking).

When stitching
delicate and

materials,
it
is
re
commended
to

a
piece

under

material
which
will
protect

Cleaning the Shuttle
Race
The
Pfaff
30
is
fitted
with
a central
bobbin
shuttle.
The
shuttle
moves
freely
in
the
divided
shuttle
race
and
is
oscillated
back
and
forth
by a
shuttle
driver.
It
has
to
be
removed
for
cleaning
and
when
thread
should
am
in
the
shuttle
race.

For this purpose proceed
as follows:
1,
Loosen wing
nut a and swing
away
race
cover R
so
thot shuttle
G becomes accessible in the race.
2. Turn the balance wheel
until
the shuttle is
at the
extreme
right.
3. Remove the shuttle
by
gripping
its center
stud
c with
thumb and forefinger
of
your left hand.
Cautiously remove
pieces
of
loose
thread
with a stiletto,
rinse the shuttle
race with cleaning
fluid (kerosene),
and
apply
sewing
machine oil.
To replace
the
shuttle, insert
it into the shuttle
race
from below, fitting
it into the position
from
which
it
was
removed.
Swing cover
R back into place
and
tighten
wing nut
a
securely so
that
it will not get
loose
when
sewing.
Fig.

Complete
disassembling
of
the
shuttle
race
will
become
necessary
from
time to
time
when
lint
and
dust
have
accumulated
in
it.

Dropping

Feed
Dog
The
Pfoff
30
has a
feed
dog
which
can be
arcpped
for
embroidering
and
darning.
To
lower
the
feed dog,
turn
clockwise the knob
(Fig.
2)
which
is
located
on
the
bed
plate
in
front
of
the
arm
standard.
It
is
raised
to
sewing position
by
turning
this
knob
counter-clockwise.
Although
it
is
not
absolutely
necessary
to
set
the stitch
regulator
lever
at
“0”
far embraidering
and
darning,
it
is
advisable
to do
so
in
order
to
ensure
smoother
and
lighter
running of the
machine.
14.
Using
the
Atfachments
All
ordinary
sewing
obs
are done
exclusively
with
the
hinged
presser foot
No.
43927
which is
attached
to
the
presser bar
of
the
machine.
We
hove
noted
repeatedly that
many housewives
use
this
presser foot
also
for
edge
stitching,
quilting,
fell
ing
and
hemming,
and
that the
attachments
which
are
destined
for
these
operations
ore
left
idle
in
the
attach
ment
kit.
This
is
wrong
because
these special
presser
feet
pro
duce
seams
whose
neat appearance
is
superior
to
any
seam
sewn
free-hand.
Therefore
you
should
not
shun the
trouble
of
exchang
ing
the
presser
foot whenever
you
want
to
do
a
spe
cial
sewing
ob
for
which
a
special
attachment
has
been
provided.
