SECTION II. OPERATOR PREVENTIVE MAINTENANCE
CHECKS AND SERVICES (PMCS)
2-3.
GENERAL. Preventive Maintenance Checks and Services (PMCS) means systematic caring, inspecting, and
servicing of equipment to keep it in good condition and to prevent breakdowns. As the operator of the DED Pump
Assembly, your mission is to:
a.
Be sure to perform your PMCS each time you operate your DED pump assembly. Always do your PMCS in
the same order, so it gets to be a habit. Once you've had some practice, youll quickly spot anything wrong.
b.
Do your BEFORE (B) PMCS just before you operate the DED pump assembly. Pay special attention to all
WARNINGS, CAUTIONS, and NOTES.
c.
Do your DURING (D) PMCS while you are operating the DED pump assembly. During operations means to
monitor the DED pump assembly and its related components while it is actually being operated. Pay special attention all
WARNINGS, CAUTIONS, and NOTES.
d.
Do your AFTER (A) PMCS right after you have operated the DED pump assembly. Pay special attention to
all WARNINGS, CAUTIONS, and NOTES.
e.
Do your WEEKLY PMCS once a week.
f.
Do you MONTHLY 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.
2-4.
PMCS PROCEDURES.
a.
Your Preventive Maintenance Checks and Services, Table 2-1, lists inspections and care to keep your DED
pump assembly in good operating condition. It is set up so you can make your BEFORE (B) Operation checks as you
perform a general examination of the DED pump assembly.
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. Carefully follow
these instructions. If you do not have tools or if the procedure tells you to, notify your supervisor.
NOTE
Terms "ready/available" and "mission capable" refer to the same status:
Equipment is on hand and ready to perform combat missions. (See DA PAM 738-
750.)
d.
The "NOT FULLY MISSION CAPABLE IF:" column in Table 2-1 tells you when your DED pump assembly is
not capable and why the DED pump assembly cannot be used.
