MICROSCOPE
SERVICING
PERSONNEL
CH Series Microscopeiswidely
used
throughout
the
world
for
training
students and inspecting various
specimens. Since
this
microscopeisfrequently
operated
for
routine
microscopy,itistobe
often
repaired
at
your
shop.
Accordingly,
this
manual shouldbehighly
helpful
for
servicing personnel.
As
you
know,
the coarse and fine adjustment mechanismofCH Seriesisnearly the
sameasthatofthe
preceding BH Series.
The
servicing personnel having experience in repairofBH Series
can
therefore easily
repair CH Series.
However,
attention
mustbepaidtothe
fact
that
CH Series
has
undergone
modificationofits coarse adjust-
ment
guide, and accordingly
this
series
currently
uses
new and
old
typesofcoarse adjustment guides.
The
old and new typesofthe
current
CH Series can
be
discriminated
from
each
other
by
a vertical line
as
illustrated below.
The
old
one was switchedtothe
new one at
the
beginningof1979.

This
manual describes repairing procedures
for
the new
typeofmicroscope
first,
and those
for
the
old
type
separatelyatthe
last part.
CH Series adopts
the
binocular
tube
whichisquite
the
sameasthatofthe BH Series.
For
repairing pro-
cedures
of
the
binocular
tube, reference should thereforebemadetothe
repair manual
for
BH Series.
"R
ight
side" and
"left
side" used in descriptions denote thoseasseenbythe
microscopist in his observing
position.
In
addition,
the mechanical stageofModel
IMTisnearly the
sameasthatofCH-MVR,
and
the
servicing
personnel should refer
to
this
manual.

Requisites
for
repairs:
1. First
of
all, ascertain
what
partsofthe
microscope
the
.userorownerofwhich wishes youtorepair.
2. Never fail

entire
functionofthe
microscope before you commence its repair.
a)
Find
out
what
prts are defective and
how
much
they
are damaged.
b)
Prior
to
repair,
think
of
the
best possible
orderofdisassembling
the
defective partsina most
efficicent way.
3. After completing
the
repair, check
the
functionsofnot
only
the
re-assembled parts
but
also
the
entire
microscope
to
make
sure no
defect
shouldbeleft unremedied.
4.
Be
carefu I
not
to
deform repair
parts
during
the
assembly; make it practicetouse tools and jigs
specified
for
purpose.
5. Make repairs
