Section III. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
To ensure that the Generator Set is ready for operation at
all times it must be inspected systematically, so that de-
fects may be discovered and corrected before they result in
serious damage or failure. The necessary preventive main-
tenance checks and services that are to be performed by the
Operator personnel are listed and described in paragraph 3-8.
3-5. CORRECTING AND REPORTING DEFICIENCIES.
Defects discovered during operation will be noted for future
correction. Stop operation immediately if a deficiency is
noted which would damage the equipment or is a safety
hazard. All deficiencies and short comings will be recorded
together with the corrective actions taken on the applicable
form. Marine Corps users should refer to current issue of
3-6. DETERMINING PMCS INTERVALS.
Certain Operator PMCS on this unit should be performed
on a - per hours of operation - basis. The running time
meter on the control panel should be used to determine the
Generator Set operating time.
3-7. PMCS FOR UNITS IN CONTINUOUS OPERATION.
For PMCS performed on an operating time basis, perform
PMCS as close as possible to the time intervals indicated.
For units in continuous operation, perform PMCS before
starting operation if continuous operation will extend
service interval past that which is shown.
3-8. PREVENTIVE MAINTENANCE CHECKS AND
Table 3-2 contains a tabulated listing of PMCS which shall
be performed by the Operator personnel. The item numbers
are listed consecutively and indicate the sequence of
definitions for operator/crew PMCS
shall be classified as follows:
Seepage of fluid (as indicated by wetness or dis-
coloration) not great enough to form drops.
Leakage of fluid great enough to form drops
but not enough to cause drops to drip from item
Leakage of fluid great enough to form drops that
fall from the item-being checked/inspected.
Equipment operation is allowable with minor
leakages (Class I or II). Of course, you must
consider the fluid capacity in the item/system
being checked/inspected. When in doubt, notify
When operating with Class I or Class II leaks,
continue to check fluid levels as required.
Table 3-2. Operator/Crew Preventive Maintenance Checks and Services
Within designated interval, these checks are to be performed in the order listed.
