TO OLYMPUS MICROSCOPE SERVICING PERSONNEL
CH Series Microscope is widely used throughout the world for training students and inspecting various
specimens. Since
this microscope is frequently operated for routine microscopy, it is to be often repaired
at
your shop. Accordingly, this manual should be highly helpful for servicing personnel.
As
you know, the coarse and fine adjustment mechanism of CH Series is nearly the same as that of the
preceding BH Series. The servicing personnel having experience in repair of BH Series can therefore easily
repair CH Series.
However,
attention must be paid to the fact that CH Series has undergone modification of its coarse adjust-
ment guide, and accordingly this series currently uses new and old types of coarse adjustment guides.
The old and new types of the current CH Series can be discriminated from each other by avertical line
as illustrated below. The old one was switched to the new one at the beginning of 1979.
CHA-F (Old type)
AA872000
Vertical line marked
CHA-F-3 (New type)
AA819500
This manual describes repairing procedures for the new type of microscope first, and those for the old type
separately at the last part.
CH Series adopts
the binocular tube which is quite the same as that of the BH Series. For repairing pro-
cedures
of the binocular tube, reference should therefore be made to the repair manual for BH Series.
"R ight side" and "left side" used in descriptions denote those as seen by the microscopist in his observing
position.
In addition, the mechanical stage of Model IMT is nearly the same as that of CH-MVR, and the servicing
personnel should refer
to this manual.

Requisites for repairs:
1. First
of all, ascertain what parts of the microscope the .user or owner of which wishes you to repair.
2. Never fail
to check the entire function of the 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 order of disassembling the defective parts in amost
efficicent way.
3. After completing
the repair, check the functions of not only the re-assembled parts but also the entire
microscope
to make sure no defect should be left unremedied.
4.
Be carefu I not to deform repair parts during the assembly; make it practice to use tools and jigs
specified
for purpose.
5. Make repairs
promptly and accurately.
