circulated
by

of
a
centrifugal
pump
from
a
reservoir
in
the
base.

BEFORE
STARTING
THE
MACHINE
the
oil
reservoir
must
be
filled
with
"TYPE
A"
or
"TYPE C"
OIL,
sold
b,
Singer
Sewing
Machine
Company.
"TYPE
C"
OIL
is
used
when
an
oil
is
desired
which
will
produce
a
minimum
of
stain
on
fabrics,
even
after
a
long
period
of
storage.
Tip
the
machine
back
on
its
hinges
and
fill
the
oil
reservoir
as
instructed
in
Fig. 5.
When
a
machine
is
NEW
or has been
idle
for
several
weeks
it
is
advisable
to
remove
the
face
plate
and
oil
the
needle
bar
and
take-up
bearings.
Oil
the
hook
as-
sembly
by
hand
and
check
the
oil
flow,
as
instructed
on
page
7.
The
automatic
oiling
system
will
function
efficiently,
after
the first
few
minutes
and
continue
to
lubricate
all
bearings.
