Section II. Preventive Maintenance Checks and Services (PMCS)
Introduction to PMCS.
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).
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.
Chapters 2-18 contain PMCS tables specific to each Reverse Osmosis Water Purification Barge
support system. 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.
PMCS columnar entries.
Item Number Column. Checks and services are numbered in chronological order regardless of
interval. This column is used as a source of item numbers for the "Item Number" column on DA
Form 2404, Equipment Inspection and Maintenance Worksheet, in recording results of PMCS.
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 mean you should do the check or service at each of those intervals.
Item to Be Inspected Column. This column lists the common name of the item to be inspected such
as "Air Filters".
Procedures Column. This column tells you how to do the required checks and services. Carefully
follow these instructions.
Equipment is Not Ready/Available if Column. This column tells you when and why your equipment
cannot be used.
The terms "Ready/Available" and "Mission Capable" refer to the same status:
equipment is on hand and is able to perform its combat missions. (See DA PAM 738-
