2.5 INTRODUCTION.
a. General. Your Preventive Maintenance Checks and Services table lists the inspections and care of
your equipment required to keep it in good operating condition. The interval column of your PMCS table
tells you when to do a certain check or service. The procedures column of the table tells you how to
do the required task. Carefully follow these instructions. If your equipment does not perform as re-
quired, refer to Chapter 3, Operator Troubleshooting Procedures.
(1)
Before You Operate. Always keep in mind the CAUTIONS and WARNINGS. Perform your Be-
fore PMCS.
(2) While You Operate. Always keep in mind the CAUTIONS and WARNINGS. Perform your During
PMCS.
(3) After You Operate. Be sure to perform your After PMCS.
(4)
lf Your Equipment Fails to Operate.
If your equipment does not perform as required, refer to
Chapter 3, Operator Troubleshooting Procedures for possible problems. Report any malfunc-
tions or failures on DA Form 2404, or refer to DA PAM 738-750.
b. PMCS PROCEDURES.
(1) Purposese of PMCS. Your Preventive Maintenance Checks and Services list the inspections and
servicing requirements necessary to keep the equipment in good operating condition.
(2) Item Number Column. Checks and services are numbered in chronological order regardless of
interval. This column is used as a source of item number for the "TM Number" column on DA
Form 2404, Equipment Inspection and Maintenance Worksheet, in recording results of PMCS.
(3) Interval Columns. The interval columns tell you when to do a certain check or service: before,
during, or after operation.
(4) Items To Be Inspected/Procedure Column.
This column lists the common name of the item to be
inspected such as “Drive Belts” and tells you how to do the required checks or services. Carefully
follow these instructions. If you do not have the tools, or if the procedures tell you to, have unit
maintenance do the work.
(5) Not Mission Capable If Column. This column tells you when and why your equipment cannot be
used.
NOTE
The terms ready/available and mission capable refer to the same status:
equipment is on hand and is able to perform its combat missions. (See DA
PAM 738-750).
