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.

2 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 a vertical line as illustrated below. The old one was switched to the new one at the beginning of 1979. CHA-F (Old type) CHA-F-3 (New type). AA872000 AA819500. Vertical line marked This manual describes repairing procedures for the new type of microscope first, and those for the old type separately at the last part.

3 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 a most efficicent way.

4 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. 1.
