bearings
and
surfaces
listed
in
.
the
chart

,
require
lubrication
.
These
have
been
properly
lubricated
,
during
assembly
at
the
factory
,
us
-
ing
the
finest
grades
of
lubricants
available
.
,
However
,
even
the
finest
oils
and
greases
have
a
tendency
to
oxidise
with
age
,
as
evidenced
by
hardening
and
darkening
in
color
.
Elimination
of
the
hardened
lubricant
is
essential
for
the
proper
operation
of
circuit
breakers
.
Also
frequent
operation
of
the
breaker
causes
the
lubricant
to
be
forced
out
from
,
be
-
tween
the
bearing
surfaces
,
A
simple
lubrication
will
often
clear
up
minor
disturbances
which
might
be
mistaken
for
more
serious
trouble
.
A
definite
lubrication
schedule
should
be
set
up
taking
into
considera
-
tion
the
frequency
of
operation
of
the
breaker
and
local
conditions
.
It
Until
such
a
schedule
is
worked
out
,
the
breaker
should
be
lubricated
at
¥
each
periodic
inspection
and
also
whenever
it
is
overhauled
,
in
accord
-
ance
with
the
lubrication
chart
,
Fig
.
20
.
It
is
also
recommended
that
all
circuit
breakers
be
operated
at
regular
intervals
to
Insure
the
user
that
the
equipment
is
operating
freely
.
The
lubrication
chart
.
Fig
.
20
,
is
divided
into
two
methods
of
lubrica
-
tion
.
The
first
method
outlines
the
maintenance
lubrication
which
should
be
performed
at
the
time
of
periodic
maintenance
,
and
requires
no
dis
-
assembly
.
The
second
method
outlines
a
lubrication
procedure
similar
to
that
performed
on
the
breaker
at
the
factory
,
but
should
be
used
only
in
case
of
a
general
overhaul
or
disassembly
for
other
reasons
,
or
if
the
operation
of
the
breaker
becomes
slower
.
