Section II. OPERATOR PREVENTIVE MAINTENANCE CHECKS
AND SERVICES (PMCS)
2-2. GENERAL.
Operator 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 APU operator, your mission is to ensure that
the APU is ready for operation at all times. It must be inspected so that defects may be discovered and corrected before
they result in damage or failure.
a.
Be sure to perform your PMCS each time you operate the APU. Always do your PMCS in the same order, so it
gets to be a habit. Once you have had some practice, you will quickly spot anything wrong.
b.
Do your BEFORE (B) PMCS before you operate the APU. Pay attention to WARNINGS, CAUTIONS, and
NOTES.
c.
Do your DURING PMCS while you operate the APU. Monitor the APU and its related components while it is
actually being operated. Pay attention to WARNINGS, CAUTIONS, and NOTES.
d.
Do your AFTER PMCS right after operating the APU. Pay attention to WARNINGS, CAUTIONS, and NOTES.
e.
Do your WEEKLY PMCS once a week.
f.
Use DA Form 2404 or 5988E (Equipment Inspection and Maintenance Worksheet) to record any faults you
discover before, during, or after operation, unless you can fix them. DO NOT record faults that you fix.
g.
Be prepared to assist unit maintenance when they lubricate the APU. Perform any other services when
required by unit maintenance.
2-3. PMCS PROCEDURES.
a.
Your Preventive Maintenance Checks and Services, Table 2-1, lists inspections and care required to keep your
APU in good operating condition. It is set up so you can make your BEFORE (B) OPERATION checks as you walk
around the APU.
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 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 APU is nonmission capable
and why the APU cannot be used.
