CHAPTER 4

REPAIR AND ALIGNING Section I. CAMERA BODY

4-1. General

In so far as possible, determine the repairs to be made before disassembling the camera. Reference to chapter 2 (troubleshooting) will assist in isolating the component requiring repair or adjustment. Disassembly beyond that necessary to make the repair or adjustment should be avoided. In most instances, sub-assemblies become accessible by removing the top plate (par. 3-4), range-viewfinder assembly (par. 3-5, and taking the inner housing from the outer housing (par. 3-6). Worn or damaged parts should be replaced before reassembling the camera.

4-2. Cleaning

WARNING: Most cleaning compounds are flammable and toxic. Do not use near an open flame. Provide adequate ventilation.

CAUTION: All components should be removed from the camera body before cleaning. Cleaning without removal may damage other components. Some sub-assemblies, after removal, may be cleaned without disassembling them. All lubricants and adhesives must be removed from components before relubricating or cementing. After cleaning, thoroughly dry the part by wiping or using compressed air.

The cleaning materials required are listed in TM 11-6720-244-12 (par. 5-2b) plus the following:
