PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
1. Maintenance Forms and Records
Every mission begins and ends with the paperwork. There isn't much of it, but you have to keep it up. The forms and
records you fill out have several uses. They are a permanent record of the services, repairs, and modifications made on
your equipment. They are reports to organizational maintenance and to your commander. And they are a checklist for
you when you want to know what is wrong with the equipment after its last use, and whether those faults have been fixed.
For the information you need on forms and records, refer to DA PAM 738-750.
2. Preventive Maintenance Checks and Services
a. Do your before (B) PREVENTIVE MAINTENANCE just before you operate the equipment. Pay attention to
the CAUTIONS and WARNINGS.
b. Do your during (D) PREVENTIVE MAINTENANCE while you operate the equipment, and at halts or rest stops.
c. Do your after (A) PREVENTIVE MAINTENANCE right after operating the equipment.
Pay attention to the
CAUTIONS AND WARNINGS.
d. Do your weekly (W) PREVENTIVE MAINTENANCE weekly.
e. Do your monthly (M) PREVENTIVE MAINTENANCE once a month.
f.
If something doesn't work, troubleshoot it with the instructions in this manual or notify your supervisor.
g. Always do your PREVENTIVE MAINTENANCE in the same order so it gets to be a habit. Once you've had some
practice, you'll spot anything wrong in a hurry.
h. If anything looks wrong and you can't fix it, write it on your DA Form 2404. If you find something seriously wrong,
report it to organizational maintenance RIGHT NOW.
i. When you do your PREVENTIVE MAINTENANCE, take along the tools you need to make all the checks. You
always need a rag or two.
WARNING
Dry cleaning solvent P-D-680 is toxic and flammable. Always wear protective goggles, and
gloves and use only in well-ventilated area. Avoid contact with skin, eyes and clothes and DO
NOT breathe vapors. DO NOT use near open flame or excessive heat. The solvent's flash point
is 100F-138F (38C-59C). If you become dizzy while using cleaning solvent, immediately get
fresh air and get medical help. If solvent contacts eyes, immediately wash your eyes with water
and get medical aid.
(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 (P-D-680) on all metal surfaces. Use soap and water when you clean
rubber or plastic material.
(2) Bolts, nuts and screws: check them all for obvious looseness, missing, bent or broken condition. You can't
try them all with a tool, of course, but look for chipped paint, bare metal or rust around bolt heads. If you find one you
think is loose, tighten it, or report it to organizational maintenance if you can't tighten it.
