Many
electrical
and
mechanical
parts
have
special
safety-related
characteristics.
These
are
often
not
evident
from
visual
inspection
nor
can
the
protection
afforded
by
them
necessarily
be
obtained
by
using
replacement
components
rated
fora
higher
voltage,
wattage,
etc.
Replacement
parts
which
have
these
special
safety
characteristics
are
identified
in
this
Service
Manual.
Electrical
components
having
such
features
are
identified
by
marking
with
a
c
ey
list

this
Service
Manual.
The
use
of
a
substitute
replacement
component
which
does
not
have
the
same
safety
characteristics
as
the
HITACHI
recommended
replacement
one,
shown
in
the
parts
list
in
this
Service
Manual,
may
create
shock,
fire,
or
other
hazards.
