2-7. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
a. GENERAL. Preventive Maintenance Checks and Services (PMCS) means systematic caring, inspecting, and serv-
icing of equipment to keep it in good condition and prevent breakdowns, As the ROWPU's maintainer, your mission
is to:
(1) Be sure to preform your SEMI-ANNUAL (SA) and ANNUAL (A) PMCS regularly.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. Pay
attention to WARNINGs. CAUTIONS, and NOTEs.
(2) se DA form 2404 (Equipment Inspection and Maintenance Worksheet) to record and faults that you dis-
cover while preforming your SEMI-ANNUAL and ANNUAL checks and services, unless you can fix them. You DO
NOT need to record faults that you fix.
(1) Your Preventive Maintenance Checks and Services. Table 2-1. lists inspections and care required to keep
your ROWPU in good operating condition. It is set up so you can make your SEMI-ANNUAL and ANNUAL checks
as you walk around the ROWPU.
b. PMCS PROCEDURES
(2) Checks and Services are numbered in chronological order regardless of interval. This column is used a a
source of tire number for the "TM Number" column on DA form 2404, Equipment Inspections and Maintenance Work-
sheet, in recording results of PMCS.
(3) The”INTERVAL”column of Table 2-1 tells you when to do a certain check or service.
(4) THE “PROCEDURE" column of Table 2-1 tells you how to do required checks and services. Carefully fol-
low these istructions. If you do not have tools. or if the procedure tells you to, notify your supervisor.
CAUTION
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)
(5) The "EQUIPMENT IS NOT READY/AVAILABLE:“ column in Table 2-1 tells you when your ROWPU
is nonmission capable and why the ROWPU cannot be used.
(6) If the ROWPU does not perform as required, refer to Troubleshooting, Table 2-2.
(7) If anything looks wrong and you can't fix it, write it on your DA form 2404. IMMEDIAATELY, report it to
your supervisor.
(8) when you do your PMCS, you will always need a rag or two. Following are checks that are common to
the entire ROWPU:
(a)
Keep It Clean. Dirt. grease, oil, and debris only get in the way and may cover up a serious problem.
Clean as you work after and as needed.
(b)
Rust and Corrosion. Check ROWPU body and frame for rust and corrosion. If any bare metal or corro-
sion exists, clean, and apply a thin coat of oil. Report it to your supervisor.
(c)
Bolts. Nuts, and Screws. Check them all for obvious looseness, missing, bent, or broken condition.
You can’t try them all with a tool. but look for chipped paint. bare metal, or rust around bolt heads. If you find a bolt,
nut, or screw you think is loose, tighten it or report it to your supervisor.
(d)
Welds. Look for loose or chipped paint. rust. or gaps where parts are welded together. If you find a
bad weld. report it to your supervisor.
