2-7. SPECIFIC PMCS PROCEDURES.
a.
Operator/Crew PMCS are provided in Table 2-1. Always perform PMCS in the order listed.
Once it becomes a habit, anything that is not right can be spotted in a minute.
b.
Before performing PMCS, read all the checks required for the applicable interval and prepare all
the tools needed. Have several clean rags (Item 14, Appendix E) handy. Perform ALL inspections at the
applicable interval.
c.
If anything wrong is discovered through PMCS, perform the appropriate troubleshooting task in
Chapter 3, Section II. If any component or system is not serviceable, or if a given service does not correct the
problem, notify your supervisor.
d.
The columns in Table 2-1 are defined as follows:
(1) Item No. Provides a logical sequence for PMCS to be performed and is used as a source
for item numbers for the "TM ITEM NO." column when recording PMCS results on DA Form 2404.
(2) Interval. Specifies the interval at which PMCS is to be performed.
(3) Item To Be Inspected. Lists the system and common name of items that are to be
inspected. Included in this column are specific servicing, inspection, replacement, or adjusting procedures to be
followed.
NOTE
The terms "ready/available" and "mission-capable" refer to the same status:
Equipment Is on hand and Is able to perform Its combat mission (AR 700-138).
(4)
Equipment Is Not Ready/Available If. Explains when and why the semitrailer cannot be
used.
2-8. LEAKAGE DEFINITIONS.
a.
It is important for you to know how fluid leakage affects the semitrailer. Following are
types/classes of leakage an operator must know to determine whether the semitrailer is mission-capable. Learn
these leakage definitions. When in doubt, notify your supervisor.
Leakage Definitions for Operator/Crew PMCS
Class I
Seepage of fluid (as indicated by wetness or discoloration) not
great enough to form drops.
Class II
Leakage of fluid great enough to form drops, but not enough to
cause drops to drip from the item being inspected.
Class III
