FOR WATER QUALITY ANALYSIS SET: PURIFICATION (WQAS-P)
OPERATOR PREVENTATIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
GENERAL.
Preventive Maintenance Checks and Services means systematic caring, inspection, and servicing of equipment to keep it in
good condition and ready to use. As the operator, your mission is to:
(1) Be sure to perform your PMCS each time you use the WQAS-P.
(2) Do your "Before" PMCS just before you use the equipment.
(3) Do your "After" PMCS right after using the equipment.
(4) Use DA Form 2404 (Equipment Inspection and Maintenance Worksheet) to record any faults that you discover before,
during, or after use, unless you can fix the fault. You DO NOT need to record faults that you fix.
PMCS PROCEDURES.

Your Preventive Maintenance Checks and Services, Table 1, lists inspections and care required to keep
the equipment in good operating condition.

The "Interval" column of Table 1 tells you when to do a certain check or service.

The "Procedure" column of table 1 tells you how to do required checks and services.
NOTE: Terms "ready/available" and "mission capable" refer to same status: Equipment is on hand and ready to perform its
mission. (See DA Pam 738-750.)

The "Equipment Is Not Ready/Available If:" column in Table 1 tells you when your equipment is non
mission capable and why it cannot be used.

f.
If anything looks wrong and you can't fix it, write it on your DA Form 2404 IMMEDIATELY, report it
to your supervisor.
