NOTE
:
If
it
becomes
neces
-
sary
to
clean
the
bearings
in
alcohol
(
shellac
thinner
)
,
be
sure
the
alcohol
is
perfectly
clean
,
and
do
not
allow
the
bearings
to
remain
in
the
alcohol
more
than
a
few
hours
.
If
it
Is
desirable
to
leave
the
bearings
in
the
alcohol
for
a
longer
time
,
an
inhibited
alcohol
such
as
is
used
for
anti
-
freeze
/
should
be
used
.
Even
then
the
bearings
should
be
removed
from
the
alcohol
within
twenty
-
four
hours
.
Esso
Anti
-
Freeze
and
Du
Pont
Zerone
are
satisfac
-
tory
for
this
purpose
.
Pre
-
cautions
against
the
toxic
effects
of
the
alcohol
must
be
exercised
by
wearing
rubber
gloves
and
by
using
the
alcohol
in
a
well
ventilated
room
;
excessive
exposure
to
the
fumes
can
be
unpleasant
TROUBLE
SHOOTING
Failure
of
a
mechanism
to
operate
properly
will
generally
fall
within
three
general
classes
;
failure
to
trip
,
failure
to
close
or
latch
closed
,
and
failure
of
closing
springs
to
recharge
.
The
following
is
a
brief
outline
showing
particular
types
of
problems
that
might
be
encountered
,
together
with
suggestions
for
remedying
the
