Before you operate, perform your before (B) PMCS. Observe all CAUTIONS and WARNINGS.
While you operate, perform your during (D) PMCS. Observe all CAUTIONS and WARNINGS.
After you operate, be sure to perform your after (A) PMCS.
If your equipment fails to operate, refer to paragraph 3-3, Operator’s Troubleshooting Procedures.
Purpose of PMCS Table. The purpose of the PMCS table is to provide a systematic methodof
inspecting and servicing the equipment. ln this way, small defects can be detected early before they become a
major problem causing the equipment to fail to complete its mission. The PMCS table is arranged with the
individual PMCS procedures listed in sequence under assigned intervals. The most logical time (before, during, or
after operation) to perform each procedure determines the interval to which it is assigned. Make a habit of doing
the checks in the same order each time and anything wrong will be detected quickly. See paragraphs 2-5 and 2-6
for an explanation of the columns in table 2-1.
