3-3. CLEANING AND INSPECTION. (CONT)
3. Clean exterior and pins of connectors of interconnecting cables with a brush. Cleaning compound may be
used with brush and cloth to remove grease, fungus, and light tarnish. When connector contacts (pins and
receptacles) exhibit corrosion, they must be replaced.
4. Keep reflective surfaces on antennas and covers on horn and polarizer assemblies clean at all times. Clean
with soft, lint-free cloth. Cloth may be used with weak solution of water and mild soap. Ground-in dirt, if
necessary, can be removed with a cloth dampened (not wet) with cleaning compound and used sparingly.
INSPECTION
During routine cleaning, visual inspections can be made for minor defects and discrepancies that could develop into
major troubles. Also during operation, unusual noises and vibrations that could cause problems at a later time should be
noted. Some typical items to be checked include the following:
1. Damaged surfaces and areas of chipped or peeling paint, corrosion, and fungus.
2. Loose, missing, or damaged mounting hardware, control knobs, switches, panel screws, headset jacks, fuse
mountings, indicator lamps, chassis handles, and connectors.
3. Loose or binding hinges.
4. Structural parts sprung or twisted out of shape, or otherwise damaged.
5. Cables and connectors loose or disconnected or loose gland nuts.
6. Broken, frayed, or cracked insulation on cables.
7. Signs of oil leaks or seepage in mechanical assemblies.
8. Correct fit and seating of equipment covers and weatherproof seals.
9. Defaced, missing, or obscured identification plates.
10. Overheated components, indicated by discoloration, blistering, bulging of containers, or leak-age of
insulating compounds, accompanied by peculiar odors.
11. Unusual noises and vibrations in mechanical assemblies during operation.
