Section Ill. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
4-5. GENERAL. Preventive Maintenance Checks and Services (PMCS) means systematic caring, in-
specting, and servicing of equipment to keep it in good condition and to prevent breakdowns. As the ROW-
PUS maintainer, your mission is to:
a. 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 MONTHLY PMCS once a month.
c. Do your SEMIANNUAL PMCS every six months.
d. Do your ANNUAL PMCS one a year.
e. Do your HOURS PMCS after the number of hours of operation listed in the table.
f. Use DA Form 2404 (Equipment Inspection and Maintenance Worksheet) to record any faults that
you discover, unless you can fix them. You DO NOT need to record faults that you fix.
4-6. PMCS PROCEDURES
a. Your Preventive Maintenance Checks and Services, Table 4-1, lists inspections and care re-
quired to keep your ROWPU in good operating condition. It is set up so you can make your 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 item 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 4-1 tells you when to do a certain check or service.
d. The PROCEDURE column of Table 4-1 tells you how to do required checks and services. Care-
fully 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: Equip-
ment is on hand and ready to perform its combat missions. (See
DA Pam 738-750)
e. The "EQUIPMENT IS NOT READY/AVAlLABLE IF: column in Table 4-1 tells you when your
ROWPU is nonmission capable and why the ROWPU cannot be used.
f. If the ROWPU does not perform as required, refer to Chapter 4, Section IV, Troubleshooting.
g. If anything looks wrong and you cant fix it, write it on your DA Form 2404. IMMEDIATELY, report
it to your supervisor.
h. When you do your PMCS, you will always need a rag or two. Following are checks that are com-
mon to the entire ROWPU:
(1) Keep It Clean. Dirt, grease, oil, and debris only get in the way and may cover up a serious prob-
lem. Clean as you work and as needed.
(2) Rust and Corrosion. Check ROWPU body and frame for rust and corrosion. If any bare metal
or corrosion exists, clean, and apply a thin coat of oil. Report it to your supervisor.
