4-6. INTRODUCTION (CONT).
i.
Fluid Leakage. It is necessary to know how fluid leakage affects the status of fuel, oil, coolant and the
hydraulic systems. The following are definitions of the different types/classes of leakage that determine the status of
the sweeper.
CAUTION
Equipment operation is allowable with minor leakage (hydraulic or water, class I or II).
Consideration must be given to the fluid capacity in the item/system being checked/inspected.
When in doubt, notify the supervisor. When operating with Class I or II leaks, continue to check
fluid levels as required in the PMCS. Class III leaks should be reported to your supervisor.
(1)
Class I. Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
(2)
Class II. Leakage of fluid great enough to form drops but not enough to cause drops to drip from item
being checked/inspected.
(3)
Class III. Leakage of fluid great enough to form drops that fall from the item being checked/inspected.
4-7. PMCS TABLE.
a.
Item Number Column. The checks and services are numbered in chronological order showing a logical
sequence around the sweeper.
b.
Interval Column. This column contains a dot (.) opposite the appropriate procedure. Thus if a given procedure
is performed quarterly, a dot is opposite the procedure in the "Q" column; if the dot is in the "S" column, the procedure
should be performed semiannually; and if the procedure is performed in two or more periods, a dot is placed in each
applicable column.
c.
Item to be Inspected Column. The items listed in this column are divided into groups indicating the portion of
the equipment of which they are a part, i.e. fuel, brakes, engine. Under these groupings a few common words are to
identify the specific item being checked.
d.
Procedures Column. This column contains a brief description of the procedure by which the check is
performed.
Refer to table 4-1 for the unit preventive maintenance checks and services for the sweeper.
