the c orners of the base. Place the machine on these pads, and
with the four studs through the rubber bushings.
CAUTION

the
AAachines
Machines
147-88,
147-110
and
147-111
are
each
equipped
with
an
oiling
system
Which
automatically
delivers
the
required
quantity
or
oil
to
all
principal
bearings.
See
large
diagrams
on
pages
18
and
19.
A
scoop
in
the
connecting
rod
takes
oil
from
the
reservoir
and
lubricates,
by
splash,
the
various
bearings
in-
side
the
machine
arm.
Some
of
this
oil
is
caught
by
a
cup
(with-
in
the
amm
from
which
it
is
distributed,
through
pipes
and
wicks,
to
the
principal
bearings
outside
the
machine
arm.
TO
INSURE
OPERATION
OF
THIS
OILING
SYSTEM,
IT IS
ESSENTIAL
THAT
THE

The
size
or the
needle
to
be
used
is
determined
by
the
size
of
the
thread
which
must
pass
freely
through
the
needle
eye.
Rough
or
uneven
thread,
or
thread
which
passes
with
(iifficulty
through
the
needle
eye,
will
interfere
with
the
proper
operation
of the
machine.
Orders

specify
the

also
the

HOW
to
Determine
the
Twist
Hold
the
thread
as
shown
above.
Turn
the
thread
over
toward
you
between
the
thumb
and
forefinger
or
the
right
hand;
If
left
twist,
the
strands
will wind
tighter;
if
right
twist,
the
strands
will
unwind.
To
Set
the
Needles
Insert
the
needle
as
far
as
it
will
go
up
into
the
needle
bar
of
Machine
147-88,
or,
in
the
case
of
Machine
147-110
or
Machine
147-111,
insert
the
needles
as
far
as
they
will
go
up
into
the
needle
clamp
-
in
every
case
with
the
single
continuous
groove
of
each
needle
toward
the
operator,
then
securely
tighten
the

To
Regulate
the
Tensions
The
tension
on
the
needle
thread,
on
Machine

is
regu-
lated
by
means
of
the
thumb
nut
(D3,F‘ig.5,
page
10),
and
on
Ma—
chines
147-110
and
147-111
by
means
of
the
thumb
nuts
(E3,Fig.8,
page
13).
To
increase
needle
thread
tension,
turn
these
thumb
nuts
to
the
right,
or
inward,
or
turn
these
thumb
nuts
to
the
left,
or
outward,
for
less
tension.
Tension
should
be
Just
enough
to
set
the

properly
in
the

For
more
tension
turn
these

inward,
toward
the
machine,
or
turn
these

The
tension
on
the
looper

To
Regulate
the
Pressure
on
the
Material
The
pressure
of
the
presser
foot
on
the
material
is
regulated
by
means
of
the
wing
nut
(P3,Fig.8,
page
13)
at
the
top
of
the
machine.
Turn
the
wing
nut
(P6)
downward
to
increase
the

sure,
or
turn
it
upward
to
decrease
the
pressure.
