(1) The preventive maintenance checks and services (PMCS) listed In the PMCS table cover procedures to be
performed by unit maintenance personnel Preventive maintenance checks and services are done to find
and fix problems before they can cause major damage to the equipment To save time and make sure that
all items are checked, do the PMCS in the order given in the table Write down any problems on the proper
forms Refer to DA PAM 738-750
(2) If something doesn't work, troubleshoot it with the Instructions In this manual or notify your supervisor
(3) Always do your preventive maintenance in the same order so it gets to be a habit
b. Procedures for Services and Inspections The following general procedures are for unit maintenance PMCS and
for all inspections They are just as important as the specific procedures In addition to the specific procedures,
any of these general procedures that apply to PMCS items will be done automatically
(1) Check to see if items are In good condition, properly assembly or stowed, not leaking, loose, or
excessively worn, and properly lubricated
(a) Checking that items are in good condition is usually a visual check to see if the items are safe and
usable Good condition means not bent or twisted, not chafed or burred, not broken or cracked, not
bare or frayed, not dented or collapsed, not torn or cut, not rusted or rotted, and not leaking
(b) Checking that items are properly assembly or stowed usually is a visual inspection also. See if the
items are in normal positions in the ROWPU and if all parts are present.
(c) Excessively worn means worn beyond usable limits and likely to fail before the next scheduled
Inspection This includes too much play (lash or lost motion) in linkages and mating parts This also
includes unreadable markings, data and caution plates, and other printed matter
(d) Check that bolts, nuts, and screws are not loose, missing, bent, or broken You can't try them all with
a tool of course, but look for chipped paint, bare metal, or rust around bolt heads Tighten any that
you find loose
(e) Inspect welds for loose or chipped paint, rust, or gaps where parts are welded together If you find a
bad weld, report It to Direct Support Maintenance
(f) Check electric wires and connectors for cracked or broken insulation, bare wires, and loose or broken
connectors Tighten loose connections and make sure the wires are in good condition
