7-3.3. Machined Surfaces And Hardware; 7-3.4. Chasis Cleaning; 7-3.5. Connector Cleaning - Aeroflex Weinschel 8310 Operation & Service Manual

Model 8310
7-3.3 MACHINED SURFACES AND HARDWARE: To remove light dirt and dust from mechanical parts such as
castings, covers and other hardware proceed as follows:
Compressed air used for cleaning and/or drying can create airborne particles that may
enter the eye. Goggles/ faceshields should be worn. DO NOT direct air stream towards
self or other personnel. Pressure should be restricted to a maximum 15 psi to avoid
personal injury.
•
Under no circumstances use a wire brush, steel wool, or abrasive compound. Using
these items will cause extensive damage to the instrument's surface.
•
DO NOT use a nylon bristle brush in solvent as the bristles may dissolve and cause
damage to the circuit card or component.
a. Use 5 psi of clean, moisture-free compressed air or preferably dry nitrogen to blow loose dirt and dust
from surface of item.
b. Briskly brush isopropyl alcohol onto area to be cleaned with a fiber-bristle brush.
c. Remove residue with lint-free cloth and repeat step "b" as a rinse.
d. When parts are thoroughly clean, dry parts using 5 psi of clean, moisture-free compressed air or
preferably dry nitrogen.
e. Clean smaller mechanical parts or hardware by dipping into a container of isopropyl alcohol. Remove dirt
by brushing with fiber-bristle brush after parts have been immersed for several hours.
f. Remove parts from isopropyl alcohol and rinse by immersing into a different container of isopropyl
alcohol.
g. When parts are thoroughly cleaned, dry parts using 5 psi of clean, moisture-free compressed air or
preferably dry nitrogen.
7-3.4 CHASSIS CLEANING: Clean chassis using a lint-free cloth moistened with water and mild detergent. For
harder to clean areas, such as inside corners of chassis, use a vacuum cleaner.
7-3.5 CONNECTOR CLEANING: Where small amounts of rust, corrosion, and/or oxide deposits are present on
connectors, clean externally with a soft-bristle brush, aluminum wool, or internally with an acid brush; then wash with
a non-corrosive solvent. MIL-C-83112 is recommended. Exercise care to ensure no metal filing or residue remains
inside the connector and the connector is thoroughly dry. Where rust, corrosion, and/or oxide deposits are present in
large quantities, replace the connector.
