Handling Acids And Alkalines - Leica FS M Bedienungsanleitung

Cleaning Objectives
Caution!
The objective may not be unscrewed during
cleaning. If damage appears on inner sur-
faces, the objectives must be sent to your
Leica subsidiary for repair. We also advise
against cleaning the inside surfaces of the
eyepieces.
The front lenses of objectives are cleaned as
described under "Cleaning Glass Surfaces". The
upper lens is cleaned by being blown off with a
pneumatic pump.
Removing Immersion Oil
Caution!
Follow safety instructions for immersion oil!
First, wipe off the immersion oil with a clean cot-
ton cloth, and then re-wipe the surface several
times with ethyl alcohol.

11.3 Handling acids and alkalines
