a. General
(1) Systematic (B) before, (D) during, (A) after, and scheduled periodic PMCS are essential to ensure
that the Reverse Osmosis Water Purification Barge Is in operational readiness at all times The
purpose of the PMCS program Is to discover and correct deficiencies and malfunctions before they
cause serious damage or failure of the barges and their support systems An effective PMCS
program requires that operators report all unusual conditions noticed before, during and after
operation as well as while performing periodic PMCS All deficiencies and malfunctions discovered
during maintenance inspections must be recorded, together with the corrective action taken, on DA
Form 2404 (Equipment Inspection and Maintenance Worksheet).
(2) A schedule for preventive maintenance inspections and service should be established and adhered
to When operating under unusual conditions, such as extreme heat or cold, It may be necessary to
perform PMCS more frequently
(3) The PMCS Items have been arranged and numbered in a logical sequence to provide for greater
efficiency and the least amount of downtime required for maintenance.

2404, Equipment Inspection and Maintenance Worksheet, in recording results of PMCS.
(2) Interval Column. The interval columns tell you when to do a certain check or service' before, during,
or after operation Sometimes a dot may be placed in more than one interval column which would
