Section II. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
(PMCS)
2-4. 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 ROWPU's operator, your mission
is to:
a. Be sure to perform your PMCS each time you operate the ROWPU. 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 ROWPU. Pay attention to WARNINGs. CAUTIONs,
and NOTEs.
c. Do your DURING (D) PMCS while you operate the ROWPU. During operation means to monitor the ROWPU
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 ROWPU. 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.
h. Be prepared to assist organizational maintenance when they lubricate the ROWPU. Perform any other services
when required by organizational maintenance.
2-5. PMCS PROCEDURES
a. Your Preventive Maintenance Checks and Services, Table 2-2, lists inspections and care required to keep your
ROWPU in good operating condition. It is set up so you can make your BEFORE (B) OPERATION checks as you walk
around the ROWPU.
b. Checks and Services are numbered in chronological order regardless of interval. This column is used as a
source of tire number for the "TM Number" column on DA Form 2404, Equipment Inspection and Maintenance
Worksheet, in recording results of PMCS.
c. The "INTERVAL" column of Table 2-2 tells you when to do a certain check or service.
d. The "PROCEDURE" column of Table 2-2 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.
