4-11. Preventive Maintenance Services
Refer to table 4-1 for a listing of preventive maintenance checks and services which must be performed by
organizational maintenance. An explanation of the tabular columns is as follows:
a. Item Number. The number appearing in this column indicates the chronological order of the checks and services
regardless of interval. This column is used as a source of item numbers for the TM Number column on DA Form 2404,
Equipment Inspection and Maintenance Worksheet, in recording results of preventive maintenance checks and services.
b. Interval. The columns headed W, M, Q, S, A, B, H and MI Contain a dot ( ) opposite the appropriate check. Thus
if a given check is to be performed weekly, a dot appears in the W column, opposite the check to be performed If the
same check is to be made in two or more periods, a dot appears in each applicable column.
c. Item To Be Inspected. This column contains an entry which identifies the item to be inspected.
d. Procedure. This column contains a brief description of the checks to be performed.
e. For Readiness Reporting, Equipment if Not Ready/Available lf. This column contains the criteria which will
cause equipment to be classified as not ready/available because of inability to perform its primary mission.
