e.
If the pump assembly does not perform as required, refer to Section III, Operator
Troubleshooting.
f.
If anything looks wrong and you can't fix it, write it on your DA Form 2404 IMMEDIATELY and
report it to your supervisor.
g.
When you do your PMCS, you will always need a rag or two. The following items are common
to all of the pump assembly components:
(1) Keep It Clean. Dirt, grease, oil, and debris only get in the way and may cover up a serious
problem. Clean as you work and as needed. Use dry cleaning solvent (Appendix E, Item
3) on all metal surfaces. Use soap (Appendix E, Item 10) when you clean rubber or plastic
material.
(2) Rust and Corrosion. Check the components of the pump assembly for rust and corrosion.
If any bare metal or corrosion exists, clean and apply a thin coat of oil. Report it to your
supervisor.
(3) Bolts, Nuts, and Screws. Check them 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 metal parts are welded
together. If you find a bad weld, report it to your supervisor.
(5) Electric Wires and Connections. 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. Look for wear, damage, or leaks and make sure clamps and fittings are tight. Wet
spots show obvious leaks, but a stain 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.
When you check for "proper operating condition", you look at the component to see if its
serviceable.
i.
Cleaning Agents.
WARNING
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 138°F (59°C).
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.
