(2) Rust and Corrosion. Check panels for rust and corrosion. If any bare metal or corrosion exists, clean, and
apply a thin coat of corrosion preventive compound (Item 5, Appendix E). Report it to your supervisor.
(3) Bolts, Nuts, and Screws. Check them all for obvious looseness, missing, bent, or broken condition. You can't
try them all with a tool, but look for chipped paint, bare metal, or rust around bolt heads. If you find a bolt, nut, or screw
you think is loose, tighten it or report it to your supervisor.
(4) Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad weld,
report it to your supervisor.
(5) Electric Wires and Connectors. Look for cracked, frayed, or broken insulation, bare wires, and loose or
broken connectors. Tighten loose connectors. Report any damaged wires to your supervisor.
(6) Hoses and Fluid Lines. Look for wear, damage, and leaks, and make sure clamps and fittings are tight. Wet
spots show leaks, but a strain around a fitting or connector can also mean a leak. If a leak comes from a loose fitting or
connector, tighten it. If something is broken or worn out, report it to your supervisor.
h. Check operating condition. Listen for unusual noise, and watch for unusual shaking or vibrations.
2-5. CLEANING AGENTS.
DO NOT use diesel fuel, gasoline, or benzene (benzol) for cleaning.
DO NOT SMOKE when using cleaning solvent. NEVER USE IT NEAR AN OPEN
FLAME. Be sure there is a fire extinguisher nearby and use cleaning solvent only in
well-ventilated places. Flash point of solvent is 140 (60 ).
USE CAUTION when using cleaning solvents. Cleaning solvents evaporate quickly
and can irritate exposed skin if solvents contact skin. In cold weather, contact of
exposed skin with cleaning solvents can cause frostbite.
a. Only use those authorized cleaning solvents or agents listed in Appendix E.
b. Keep cleaning solvents, gasoline, and lubricants away from rubber or soft plastic parts. They will deteriorate
c. When cleaning grease buildup or rusty places, use a cleaning solvent (Item 6, Appendix E). Then apply a thin coat
of corrosion preventive compound (Item 5, Appendix E) to affected area.
2-6. LEAKAGE DEFINITIONS FOR OPERATOR PMCS.
It is necessary for you to know how fuel leaks affect the status of the heater. Following are classes of leaks an
operator needs to know to determine the operational status of the heater. Learn these leakage class definitions.
Remember-when in doubt, notify your supervisor.
