Organizational Preventive Maintenance
General
Checks and Services
To ensure that the semitrailer is ready for operation at all times, it must be inspected systematically so
that defects may be discovered and corrected before they result in serious damage or failure. Table 4-2
contains a tabuIated listing of preventive maintenance checks and services to be performed by organizational
maintenance personnel. All deficiencies and shortcomings will be recorded as well as the corrective action
taken on DA Form 2404 at the earliest possible opportunity.
4-12. ORGANIZATIONAL PREVENTIVE MAINTENANCE CHECKS AND SERVICES
a. The item numbers of table 4-2 indicate the sequence of the PMCS. Perform at the intervals shown below:
(1) Do your (S) PREVENTIVE MAINTENANCE once each 6 months.
(2) Do your (A) PREVENTIVE MAINTENANCE once each year.
b. If something doesn't work, troubleshoot it with the instructions in this manual or notify your supervisor.
c. Always do your preventive maintenance in the same order, so it gets to be a habit. Once you've had some
practice, you'll spot anything wrong in a hurry.
d. If anything looks wrong and you can't fix it, write it down on your DA Form 2404. If you find some-
thing seriously wrong, report it to direct support as soon as possible.
Cleaning solvent (Fed.Spec PD-680) is both toxic and fIammable. Avoid
prolonged breathing of vapors. Avoid skin contact. Use only in a well-
ventilated area. Keep away from open flame.
Keep it clean: Dirt, grease, oil and debris only get in the way and may cover up a serious problem.
(1)
Clean as you work and as needed. Use dry cleaning solvent (PD-680) (item 18, Appendix C) to
clean metal surfaces. Use soap and water when you clean rubber or plastic materiel.
(2) Bolts, nuts and screws: Check that they are not loose, missing, bent or broken. You can't try
them all with a tool of course, but look for chipped paint, bare metal, or rust around bolt heads.
Tighten any that you find loose.
(3) Welds: Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find
a bad weld, report it to direct support.
(4) Electric wires and connectors. Look for cracked or broken insulation, bare wires, and loose or
broken connectors. Tighten loose connections and make sure the wires are in good condition.
(5) Hoses and fluid lines. Look for wear, damage and leaks. Make sure clamps and fittings are tight.
Wet spots show leaks of course, but a stain around a fitting or connector can mean a leak. If a
leak comes from a loose fitting or connector, tighten it. If something is broken or worn out,
either correct it or report it to direct support (refer to MAC, Appendix B).
