Nikon Eclipse E400 POL User Manual

Any
oil
remaining
on an
oil-immersion
type
of
objective
or
staining
on
the
tip
of
a
dry
type
of
objective
has
a
negative
effect
on
viewing.
After
using
oil,
wipe
all
of
it
away
and
make
sure
t
there
is
no
oil
on
the
tips
of
the

objectives.
Use
petroleum
benzine
to
wipe
away
immersion
oil.
Removing
the
oil
and
wiping
with
absolu
alcohol
(ethyl
alcohol
or
methyl
alcohol)
will
complete
cleaning.
If
you
cannot
obtain
petroleum
benzine,
use
methyl
alcohol.
Note
that
methyl
alcohol
does
not
clean
as
well
as
petroleum
benzine
and
it
will
be
necessary
to
repeatedly
wipe
the
surfaces
(th
or
four
times
is
usually
sufficient
to
clean
the
lenses.)
