TO
OPERATE
THE
MACHINE
1. Raise
feeding
foot A, Fig. S by
moving
lifter B
upward.
2. Place
both
feet
upon
the
treadle.
3. Turn
top
of
hand
wheel
over
toward
you to
start
machine.
(If
hand
wheel
is
fitted on front of
machine,
turn
top
of
hand
wheel
from left to
right
to
start
machine.)
4.
Allow
the
feet
to
move
freely with
the
motion
of
the
treadle.
Continue this motion with
an
alternating
pressure
of
heel
and
toe until a
regular
easy
movement
is
acquired
and
the
hand
wheel
is
kept
in
continuous
rotation
by
use
of
the
feet
alone.
5.
When
familiar
with the
treadle
movement,
and
you
are
able
to
re-start
the
machine
without
turning the
hand
wheel
in
the
wrong
direction,
place
a piece of
material
under
the
feeding
foot.
6. Lower
feeding
foot
by
lowering
lifter
and
oper-
ate
machine
until you
have
become
accustomed
to
guiding
the
material.
Material
is
moved
along
by
the
feeding
foot only,
and,
the
direction of stitching
can
be
changed
as
de-
sired,
by
turning
wings, Fig.32.
To
make
a
curved
line
of
stitching,
operate
machine
slowly
and,
without
turning
work,
turn
the revolving
wings
enough
to pro-
duce
the
desired
curve.
Feeding foot rises
between
each
stitch
while
needle
is
in
the
material.
With
needle
serving
as
pivot,
ma-
terial
can
be
turned
in
any
direction.
When
desired,
the
feeding
foot
may
be
fixed to
work
in
a
straight
line, in
any
direction,
by
tightening
the
knurled
screw
A, Fig. 22.
Never
turn
the
work
or
alter
the
direction
of
the
feed
while
the
foot
is
pressing
on
the
material,
as
this
may
cause
missed stitches
and
damage
the
surface
of
the
work.

NEEDLES
Needles
for
MACHINES 29K71, 29K72
and
29K73
are
of
Class
and
Variety
29
x 3
for
cloth
and
29
x 4
for
leather.
Needles
29
x 3
are
made
in
sizes 11,
14,
16, 17, 18, 19, 21, 22, 23,
24
and
25, Needles
29
x 4
are
made
in sizes 9, 11, 14, 16, 18, 19, 21,
22, 23,
24
and
25.
The
above
needles
regularly
have
nickel finish
but
can
be
supplied
with chromium finish if
ordered.
The size
of
the
needle
to
be
used
should
be
deter
-
mined
by
the
size
of
the
thread
which must
pass
freely
through
the
eye
of
the
needle.
Rough
or
uneven
thread,
or
thread
which
passes
with difficulty
through
the
eye
of
the
needle
will
interfere
with
the
successful
use
of
the
machine.
Orders
for
needles
must
specify
the
Quantity
re-
quired,
the
Size
number,
also
the
Class
and
Variety
numbers
separated
by
an
x.
The
following
is
an
example
of
an
intelligible
order:
"1
00
No. 16,
29
x 3 Needles",
for
cloth.
"1
00
No. 16,
29
x 4 Needles", for
leather.
The
best
stitching results will
be
obtained
by
using
the
needles
sold
by
Singer
Sewing
Machine
Company.
THREAD
Left twist
thread
should
be
used
in
the
needle.
Either right
or
left twist
thread
can
be
used
for
the
bobbin.
To
determine
the
twist, hold
the
thread
as
shown.
Turn
the
thread
over
toward
you
between
the
thumb
and
forefinger
of
the
right
hand;
if left twist,
the
strands
will
wind
tight
er.
If
right twist,
the
strands
will
unwind
.
