AND
MAINTENANCE
Avoid touching
the lens surfaces
with
fingers or
any
rough material.
For
dusting,
use a
soft
camel
hair
brush
and then
wipe the
lens surfaces
lightly
with a
well-washed soft cotton
cloth. Wet
the cloth with
xylol, but
never
alcohol
or ether
for
wiping
off
finger marks or
grease.
The
microscope
stand
surfaces should
be dusted
in the same
way and
may
be slightly
oiled,
Tension
of the coarse
focus knobs
should
be adjusted,
in this
type
(S-Kt)
of microscope, by
means of the adjusting
ring, not by twisting
the
knobs.
Dismantling
of the
internal optical
parts
and
the
microscope body should
not be attempted,
because it
may interfere
with the
performance
of
the
instrument.
lt should be
done
only by an
expert
or the original
manufacturer.
Do
not
apply
grease
of an
unspecified
type to the sliding
surfaces
of the
coarse
focusing adjustment
or the
gliding
stage.
lf
necessary,
contact
your
dealer
or the manufacturer.
Avoid any
forcible manipulation
of the
moving
parts.
At all
times, the
instrument should
be
handled carefully
e.g.
for
carrying
the
microscope,
hold thet base
with one hand and
the arm
with
the
other. For
transportation,
pack
the body
tube,
rectangular
or circular stage
and
lenses-objectives,
eyepieces and
condenser-in
a
separate
contai
ner.
Protect the
microscope
from
dust
and store
in a dry
place.
When
not in
use, it
should
be covered with
the vinyl
cover or
kept in the
cabinet
which
is available
on order.
When storing
it in the
cabinet, do
not
forget to
tighten
the locking
screw
of the
eyepiece tube.
Place
the support
under the
microscope substage
and secure
it. Fasten
the
holding screws
for the
microscooe
at
the
cabinet bottom.
lt is
recommended
that
the objectives
and
eyepieces
be
kept in
a
container
with desiccant.
Sufficient
brightness
can not be
obtained in
interference-phase-contrast
observation
using
the
binocular
Model
S-Kt
at a
magnification
of
600x
or
h igher.
The
Model
S-Ke
or
L-Ke is
recommended
for use with
interference
phase
contrast.
The circuit
in the
microscope is designed
to
minimize the
occurence
of
electrical interference.
Use the microscope at
a distance of
at least 1-2
meters away
from an AF
short
wave
receiver
or
a
noise may be
heard in
the
reception.
Also, the
instrument
must be
kept 2 meters
or
more
from
a
electro-
encephalograph
in a clinical
examination
room.
When taking
electro-cardiograms,
however, it
is
found by
practical
tests
that there
is no need
for
taking
this
precaution.
