OPERATORS PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
2-3. GENERAL. Preventive Maintenance Checks and Services (PMCS) means systematic caring, inspect-
ing, and servicing of equipment to keep it in good condition and to prevent breakdowns. As the FAWPSS oper-
ator, your mission is to:
a. Be sure to perform your PMCS each time you operate the FAWPSS. Always do your PMCS in the
same order, so it gets to be a habit. Once youve had some practice, youll quickly spot anything wrong.
b. Do your BEFORE (B) PMCS just before you operate the FAWPSS. Pay attention to WARNINGS.
CAUTIONS, and NOTES.
c. Do your DURING (D) PMCS while you operate the FAWPSS. During operation means to monitor
the FAWPSS and its related components while it is actually being operated. Pay attention to WARNINGS,
CAUTIONS, and NOTES.
d. Do your AFTER (A) PMCS right after operating the FAWPSS. Pay attention to WARNINGS, CAU-
TIONS, and NOTES.
e. Do your WEEKLY (W) PMCS once a week.
f. Do your MONTHLY (M) PMCS once a month.
g. Use DA Form 2404 (Equipment Inspection and Maintenance Worksheet) to record any faults that
you discover before, during. or after operation, unless you can fix them. You DO NOT need to record faults
that you fix.
h. Be prepared to assist unit maintenance in any lubrication procedures. Perform any other services
when required by unit maintenance.
a. Your Preventive Maintenance Checks and Services, Table 2-1, lists inspections and care required
to keep your FAWPSS in good operating condition. It is set up so you can make your BEFORE (B) OPERA-
TION checks as you perform a general examination of the FAWPSS.
b. The INTERVAL column of Table 2-1 tells you when to do a certain check or service.
c. The PROCEDURE column of Table 2-1 tells you how to do required checks and services. Careful-
ly follow these instructions. If you do not have tools, or if the procedure tells you to, notify your supervisor.
Terms ready/available and mission capable refer to same status: Equipment is on
hand and ready to perform its combat missions. (See DA Pam 738-750)
d. The NOT FULLY MISSION CAPABLE IF: column in Table 2-1 tells you when your FAWPSS is
nonmission capable and why the FAWPSS cannot be used.
e. If the FAWPSS does not perform as required, refer to Chapter 3, Section II, Troubleshooting.
