Section II. PREVENTIVE MAINTENANCE CHECKS
AND SERVICES (PMCS)
2-2. GENERAL.

containment area or performing its intended mission. Always keep in mind the
CAUTIONS and WARNINGS. Perform your BEFORE PMCS.
b. During. Checks begin when the equipment is being used in its intended mission.
Always keep in mind the CAUTIONS and WARNINGS. Perform your DURING PMCS.
c. After. Checks and services begin when the equipment is taken out of its mission
mode or returned to its containment area. Be sure to perform your AFTER PMCS.
d. Quarterly. Perform quarterly checks and services every 90 days unless equipment
is in permanent storage.
e. If Your Equipment Fails To Operate Troubleshoot with proper equipment. Report
.
any deficiencies with the proper forms. See DA PAM 738-750.
2-3. PMCS PROCEDURES.
a. General. Table 2-2 contains operator's PMCS procedures. The procedures are
arranged in a logical sequence requiring a minimum amount of time and motion on the
part of the person(s) performing them and are arranged so there will be a minimum of
interference between person(s) performing checks simultaneously on the same end item.
b. Item No. Column Checks and services are numbered in chronological order
.
regardless of interval. Use this column as a source of item numbers for the "TM Number"
column on DA Form 2404, Equipment Inspection and Maintenance Worksheet, in
recording results of PMCS.
c. Interval Column The words in the Interval column indicate when the checks or
.
services are to be done as follows:
(1) If a given check is performed before, during, or after an operation, the word
BEFORE, DURING or AFTER will be in this column, respectively.
(2) If the same check is made at two or more intervals, the appropriate words will
appear in the column.
d. Location, Item to Check/Service Column Indicates location and/or the item to be
.
checked and/or serviced. The items to be inspected are identified by as few words,
usually the common name, as will clearly identify the item, e.g., "Drive Belts."
e. Procedure Column This column briefly describes the procedure by which the
.
check is performed. It contains all the information required to perform the checks and
services, including appropriate tolerances, adjustment limits, and instrument gage
readings.
f. Not Fully Mission Capable If: Column This column contains the criteria that will
.
cause the equipment to be classified as not mission capable because of inability to
perform its primary mission. An entry in this column will:
(1) Identify conditions that make the equipment not mission capable for
readiness reporting purposes.
(2) Deny use of the equipment until corrective maintenance has been performed.
