Section II. OPERATOR PREVENTIVE MAINTENANCE CHECKS
AND SERVICES (PMCS)
Preventive Maintenance Checks and Services (PMCS) means systematic caring, inspecting, and servicing of equipment to
keep it in good condition and to prevent breakdowns. As the trailers operator, your mission is to:
Be sure to perform your PMCS each time you operate the trailer. Always do your PMCS in the same order, so
it gets to be a habit. Once youve had some practice, youll quickly spot anything wrong.
Do your BEFORE PMCS just before you operate the trailer. Pay attention to WARNINGs, CAUTIONs, and
Do your DURING PMCS while you operate the trailer. During operation means to monitor the trailer and its
related components while it is actually being operated. Pay attention to WARNINGs, CAUTIONs, and
Do your AFTER PMCS right after operating the trailer. Pay attention to WARNINGs, CAUTIONs, and NOTEs.

item number for the TM ITEM NO. column when recording PMCS results on DA Form 2404.
The INTERVAL column tells you when to do a certain check or service.
The LOCATION column lists the item to check or service.
The PROCEDURE column tells you how to do the required check or service. Carefully follow these
instructions. When instructed to do so, notify Unit maintenance.
The terms "ready/available" and "mission capable" refer to the same status: Equipment is on
hand and ready to perform its combat missions. (See DA Pam 738-750.)
The NOT FULLY MISSION CAPABLE IF column tells you when your trailer is nonmission capable and why
the trailer cannot be used.
