2-12. Explanation of PMCS Table. PMCS is designed to keep the equipment in good working condition. This
is accomplished by performing certain test, inspections, and services. Table 2-1 lists items to be serviced and
the procedures needed to accomplish the PMCS. The "Interval" column tells you when to perform a check or
service. If needed, PMCS may be performed more frequently than the indicated interval. The "Procedures"
column tells you how to perform the required checks and services.
If your equipment does not perform as
required, see Table 2-2, Troubleshooting. Report any malfunctions or failures on DA Form 2404. In the "TM"
Number column on DA Form 2404, record the appropriate Item Number from the PMCS table.
2-13. Intervals. Each PMCS time interval, except for daily and monthly, has a corresponding hours interval.
These intervals, along with the repeat check requirements, are as follows:
a. Daily. Every 24 hours.
b. Monthly. Every 30 days.
c. Quarterly. Every 3 months or 250 operating hours (whichever occurs first). Repeat all daily and
quarterly checks.
d. Annually. Every 12 months or 1000 operating hours (whichever occurs first). Repeat all daily and
quarterly checks.
e. Biennially. Every 24 months or 2000 operating hours (whichever occurs first). Repeat all daily,
