Section III. UNIT PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
PARA. NO.
TITLE
4-8.
GENERAL
Ensure the semitrailer is ready for operation at all times. Inspect it within specified intervals so that defects are found and
corrected before any serious damage or failure occurs. This section contains a listing of PMCS to be performed. Record
all deficiencies, as well as the corrective action taken, on DA Form 2404, Equipment Inspection and Maintenance
Worksheet, as soon as you can. Perform all operator/crew PMCS before performing these procedures.
a. Item numbers in the PMCS table indicate the PMCS sequence. Use these item numbers for the "TM Number"
column on DA Form 2404.
b. If a part or component does not operate as it should, troubleshoot it using the procedures in this manual and
notify your supervisor.
c. Always perform preventive maintenance in the same order so that it gets to be a habit. Once you have had some
practice, you will spot anything wrong in a hurry.
d. If something appears to be wrong and you cannot repair it, write it down on your DA Form 2404. If you find
something seriously wrong, report it to Direct Support (DS) maintenance as soon as possible.
WARNING
Dry cleaning solvent (P-D-680, Type III) is used to clean parts and is potentially
dangerous to personnel and property. Extinguish all smoking materials and do not
allow sparks or open flames near the work area. Use skin and eye protection and
work in a well-ventilated area. Flash point of dry cleaning solvent is 200F (93C).
(1) Keep it clean: Dirt, grease, oil, and debris may cover a serious problem. Clean as you work and as needed.
Use dry cleaning solvent (item 26, appx. E) to clean metal surfaces. Use soap and water when you clean
rubber or plastic materials.
(2) Bolts, nuts, and screws: Check to be sure that bolts, nuts, and screws are not loose, missing, bent, or
broken. Although it is not necessary to check them all with a tool, look for chipped paint, bare metal, or rust
around bolt heads. Tighten all loose hardware.
(3) Welds: Inspect welds for chipped paint, rust, or gaps where parts are welded together. Bad welds must be
reported to DS maintenance.
