Section IV. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)

4-6. GENERAL

Systematic, periodic, preventive maintenance checks (PMCS) are essential to ensure that the reeling

machine is ready for operation in any mode at all times. The purpose of a preventive maintenance pro-

gram is to discover and correct defects and deficiencies before they can cause serious damage or

complete failure of the equipment. Any effective preventive maintenance program must begin with the

training of operators to report all unusual conditions noted during daily checks or actual operation to

organizational maintenance. All defects and deficiencies discovered during maintenance inspections

must be recorded, together with corrective action taken, on DA Form 2404 (Equipment Inspection and

Maintenance Worksheet).

4-7. INSPECTION AND SERVICE

A schedule for organizational preventive maintenance inspection and service should be established

immediately after installation of the reeling machine. A quarterly interval, equal to three calendar

months or 250 hours of operation, whichever occurs first, is recommended for usual operating

conditions. When operating under unusual conditions, such as a very dusty or sandy environment, it

may be necessary to reduce the interval to monthly or even less if conditions are extreme.

Table 4-1 lists the organizational preventive maintenance checks and services that should be per-

formed at quarterly (or otherwise established) intervals. The PMCS items in the table have been

arranged and numbered in a logical sequence to provide for greater personnel efficiency and least

amount of required maintenance downtime.
