2-5. Specific PMCS Procedures (cont'd)
d. Explanation of column headings in Table 2-1 are as follows:
Item No. The item number column of your PMCS table is used for reference. When completing DA
Form 2404, include the item number for the check/service indicating a fault. Item numbers also appear in
the order that you must do checks and services for the intervals listed.
Interval. This column of your PMCS table tells you when to do a certain check or service.
Item to be inspected. This column of your PMCS table names the item to be checked or serviced.
Procedure. This column of your PMCS table tells you how to do the required checks and services.
Carefully follow these instructions. If you do not have the tools, or the procedure tells you to, have unit
maintenance do the work.
Not Fully Mission Capable If: This column tells you when and why your equipment cannot be used.
2-6. Leakage Definitions
a. It is important to know how fluid leakage affects the status of the semitrailer. The following are definitions
of the types/classes of leakage an operator must know to be able to determine whether the semitrailer is
mission capable. Learn these leakage definitions. When in doubt, notify your supervisor.
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 item
being checked/inspected.
Class III: Leakage of fluid great enough to form drops that fall from the item being
checked/inspected.
CAUTION
Equipment operation is allowable with minor leakages (Class I or II). Of course,
consideration must be given to the fluid capacity in the item/system being checked/
inspected. When in doubt, notify your supervisor. Operation with major leakages
may cause equipment damage.
When operating with Class I or II leaks, continue to check fluid levels as required in your PMCS. Class III
leaks should be reported to your supervisor or unit maintenance.
b. Equipment operation is allowed with minor leakages (Class I or II). Fluid levels in an item/system affected
with such leakage must be checked more frequently than required in PMCS. When in doubt, notify your
supervisor.
c. Report Class III leaks IMMEDIATELY to your supervisor or unit maintenance.
