Section II. PREVENTIVE MAINTENANCE CHECKS AND SERVICES

(PMCS)

2-4. GENERAL

Your Preventive Maintenance Checks and Services (Table 2-1) lists the inspection and care of your equipment required

to keep it in good operating condition. Every mission begins and ends with the paperwork. There isn't much of it, but you

have to keep it up. The forms and records you fill out have several uses. They are a permanent record of the services,

repairs, and modifications made on your vehicle. They are also a checklist for you when you want to know what was

wrong with the vehicle after its last use and whether those faults have been repaired. For the information you need on

forms and records, see DA Pam 738-750.

2-5. OPERATOR/CREW PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)

a. Do your before (B) PMCS just before you operate the vehicle.

b. Do your during (D) PMCS while the equipment and/or its component systems are in operation.

Do your after (A) PMCS right after operating the vehicle.

d. Do your weekly (W) PMCS once a week.

e. Do your monthly (M) PMCS once a month.

If something does not work, troubleshoot it with the instructions in this manual or notify your supervisor.

g. Always do your PMCS in the same order so it gets to be a habit. Once you've had some practice, you'll spot

anything wrong in a hurry.

h. When you do your PMCS, take along a rag or two.

i. While performing PMCS, observe WARNINGS and CAUTIONS that could endanger your safety or result in

damage to the equipment.

j. Your Preventive Maintenance Checks and Services (Table 2-1) is made up of four columns. It is important to

follow each column in order of the item being inspected/serviced.

(1) Column 1 indicates the item number of the inspection to be performed.

(2) Column 2 indicates at which interval the inspection is to be performed.

(3) Column 3 indicates the item to be inspected.

It will tell you what to inspect/service and the required

procedures to complete the inspection.

(4) Column 4 indicates the readiness of the equipment based on the inspection/service. If there is an entry in this

column, the problem must be solved before the vehicle can be used.

k. If anything looks wrong and you can't fix it, write it on your DA Form 2404. The Item No. column on the PMCS

table is the source for item numbers used on the TM Number Column on DA Form 2404. If you find something seriously

wrong, report it to unit maintenance RIGHT NOW.
