Preventive Maintenance Checks and Services (PMCS).
Section I.
3-1. PMCS INTRODUCTION.
This section contains Unit PMCS requirements for the IHMEE. The PMCS tables contain checks and services necessary to
ensure the vehicle is ready for operation. Using PMCS tables, perform maintenance at specified intervals.
3-2. MAINTENANCE FORMS AND RECORDS.
Every mission begins and ends with paperwork. There is not much of it, but it must be kept up. The completed forms and
records have several uses. They are a permanent record of services, repairs, and modifications made on the vehicle. They are
reports to Unit Maintenance and to your Commander. They are a checklist to know what was wrong with the vehicle after its
last use, and whether those faults have been fixed. For information needed on the forms and records, see DA PAM 738-750.
3-3. PREVENTIVE MAINTENANCE CHECKS AND SERVICES.
a. Do the semiannual (S) PREVENTIVE MAINTENANCE once every 6 months or every 12,000 mi. (20 000 km),
whichever comes first. Pay attention to the CAUTIONS and WARNINGS.
b. Do the annual (A) PREVENTIVE MAINTENANCE once a year or every 24,000 mi. (40 000 km), whichever comes
first. Pay attention to the CAUTIONS and WARNINGS.
c. If something does not work, troubleshoot with instructions in Para 3-16.
