PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) - Continued
Complete ANNUAL PREVENTIVE MAINTENANCE once each year and/or every 250 hours, whichever
comes first.
Complete BIENNIAL PREVENTIVE MAINTENANCE once every 2 years and/or every 500 hours, whichever
comes first.

PREVENTIVE MAINTENANCE is mastered, it should allow you to spot any discrepancies, even in a rushed
situation.
If something does not work, troubleshoot per instructions in the troubleshooting section of this publication.
If anything looks wrong and is not fixed immediately upon discovery, complete either a DA Form 2404 or
DA FORM 5988E.
When completing PREVENTIVE MAINTENANCE, always take along the tools needed to make all the
required checks (including one or two clean rags).
