Section IV. UNIT PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
2-7. INTRODUCTION.
a.
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 to
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.
b.
If something doesn't work, troubleshoot it with the instructions in this manual or notify your supervisor.
c.
Always do your preventive maintenance in the same order so it gets to be a habit. Once you have had some
practice, you will spot anything wrong in a hurry.
2-8.
PROCEDURES FOR SERVICES AND INSPECTIONS. The following general procedures are for unit
maintenance PMCS and for all inspections. They are just as import as the specific procedures. In addition to the
specific procedures, any of these general procedures that apply to PMCS items will be done automatically.
a.
Check to see if items are in good condition, properly assembled or stowed, not leaking, loose, or excessively
worn, and properly lubricated.
(1) 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.
(2) Checking that items are properly assembled 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.
(3) 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 unbreakable
markings, data and caution plates, and other printed matter.
(4) 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.
(5) 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.
