NOTE
To ensure that the Generator Set is ready for operation at all times
it must be inspected systematically, so that defects may be dis-
covered and corrected before they result in serious damage or
failure, The necessary preventive maintenance checks and services
that are to be performed by the Operator personnel are listed and
described in paragraph 3-8. For ASK equipped generators, checks
and services will be limited to those areas that can be inspected
through ASK access doors.
3-5. CORRECTING
AND
REPORTING
DEFI-
CIENCIES.
Defects discovered during operation will be noted
for future correction. Stop operation imediately if
a deficiency is noted which would damage the equip-
ment 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 per-
formed on a per hour of operation - basis. The
running time motor on the control panel should be
used to determine the Generator Set operating time.
3-7. PMCS FOR UNITS IN CONTINUOUS OPERATION.
Leakage definitions for operator/crew
PMCS shall be classified as follows:
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 Ill

consider the fluid capacity in the item/system being
checked/inspected. When in doubt, notify your
supervisor.
When operating with Class I or Class II Ieaks,
continue to check fluid Ievels as required.
For PMCS performed on an operating time basis,
perform PMCS as close as possible to the time in-
tervals indicated. For units in continuous operation,
perform PMCS before startlng operation if contin-
uous operation will extend service Interval past that
which is showen.
