Figure 4 shows the underside of the 211
G155
MACHINE
and
Fig. 5 that of the
211
0156
MACHINE
with the lubrication points for both machines.
They
can
be oiled
when
the
machine
is
tilted
bock
on
its
hinges.
Figure 5
Figure 6 shows the hook lubrication points
"G"
and
"H"
which
can be reached after opening the right hand
bed slide. The oil reservoir "G" oils the upper hook
bearing and the mechanism for the mechanical opener.
The small
green
felt
"H"
on the bobbin
case
oils the
Figure 6
hook raceway and should always be saturated with oil.
If the felt
appears
almost black, then
there
is sufficient
oil. If it is dry, then the color is a light green. On a new
machine,
the
felt
should
be
oiled
each
time
the
bobbin
is
changed.
NEEDLES
Original Singer Needles, Catalog No. 3355
(135x17)
which
are
available
in
sizes
9-26
should
be
used
for
this machine. The needle size is determined by the size
of the
thread,
which should run freely through the
needle eye. Rough
and
non-uniform
thread
that
does
not run freely through the eye interferes with the proper
function
of
the
machine.
Orders
for
needles
should
in
clude the desired auantity, the
catalog
number, the
size,
and
the type. Tne type is shown with a suffix:
1 - chrome plated, 2 - nickel plated, 3 - special fine
point.
Example: 100
-3355
- 12
-1
(100 needles - Catalog No. 3355 -
Size 12 - Chrome Plated)
Needles
and
package carry the name: SINGER.
THREAD
(Figure 7)
Left-twist
thread
should
be
used
in
the
needle.
Either
right or left twist can be used in the bobbin.
To
determine
the
thread
twist, hold
the
thread
as
shown in Figure 7. Turn it between thumb
and
forefin
ger
of the right hand counter-clockwise (towards you).
If left twist, the strands
will
wind tighter; if right twist,
the
strands
will
unwind.
Based on past experience, the following needle sizes
are
recommended
for
the
different
threads.
