Section II. OPERATOR'S 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 equipment operator, your mission is to:
a.
Be sure to perform your PMCS each time you operate the equipment. Always do your PMCS in the same
order, so it gets to be a habit. Once you've had some practice, you'll quickly spot anything wrong.
b.
Do your BEFORE (B) PMCS just before you operate the equipment. Pay attention to WARNINGS,
CAUTIONS, and NOTES.
c.
Do your DURING (D) PMCS while you operate the equipment. During operation means to monitor the
equipment 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 equipment. Pay attention to WARNINGS, CAUTIONS,
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.

PMCS PROCEDURES.
a.
Your Preventive Maintenance Checks and Services, Table 2-1, lists inspections and care required to keep
your equipment in good operating condition. It is set up so you can make your BEFORE (B) OPERATION
checks as you walk around the equipment. The ITEM column of Table 2-1 is a numeric listing of the
sequence in which the services and inspections are performed.
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.
