OPERATOR/CREW PREVENTIVE MAINTENANCE
CHECKS AND SERVICES INSTRUCTIONS (PMCS)
To ensure that the M872A4 Semitrailer is ready for operation at all times, it must be inspected on a
regular basis so that defects may be found before they result in serious damage, equipment failure,
or injury to personnel. This section contains systematic instructions on inspections, adjustments,
and corrections to be performed by the operator/crew.
While performing PMCS, read and follow all safety instructions in the warning summary at the front
of this manual. Keep in mind all warnings and cautions throughout PMCS.
Perform PMCS, found in Table 3, at the following intervals:
Perform "Before" PMCS before operating the semitrailer.
Perform "During" PMCS while operating the semitrailer.
Perform "After" PMCS immediately after operating the semitrailer.
Perform "Weekly" PMCS procedures, must be done once each week on semitrailer.
Perform "Monthly" PMCS procedures, must be done once each month on semitrailer.
All defects that the operator cannot fix must be reported on a DA Form 2404, Equipment Inspection
and Maintenance Worksheet, or an electronic DA Form 5988E, if available, immediately after
completing PMCS. If a serious problem is found, immediately report it to your supervisor.
Remember, record any corrective action taken.
GENERAL PMCS PROCEDURES
Dry cleaning solvent is toxic and flammable. Always wear protective
goggles and gloves, and use only in a well-ventilated area. Avoid contact
with skin, eyes, and clothes, and DO NOT breathe vapors. DO NOT use
near open flame or excessive heat. The solvent's flash point is
100F-138F (38C-59C). If you become dizzy while using cleaning solvent,
immediately get fresh air and medical help. If solvent contacts eyes,
immediately wash your eyes and get medical aid.
1. Keep equipment clean. Dirt, oil, and debris may cover up a serious problem. Clean as you work and
as needed. Use dry cleaning solvent (WP 0086 00-3) on all metal surfaces. Use soap and water on rubber,
plastic, and painted surfaces.
