2-2. GENERAL
To ensure that the MMS is always ready for operation, each major component/LRU must be inspected so that
defects can be discovered and corrected to prevent serious damage or failure. The Preventive Maintenance
Checks and Services (PMCS) that must be performed are listed and described in table 2-6. The PMCS table
indicates what to check, when to check, and the condition(s) to check for. The Item Number column lists the
number assigned to each PMCS inspection. This column is to be used as the source of item numbers for the "TM
Number" column on DA Form 2404. The Interval column defines when the PMCS procedures are to be
performed. The Item To Be Inspected column divides the system into the major components to be inspected.
There is no preferred order of inspecting the various components, and for the convenience of the user, they are
listed in alphabetical order for quick reference. The Procedure column provides a brief description of the check or
inspection to be performed. The procedures should be performed in the sequence listed to minimize the effort
required to perform the PMCS inspections.
Follow the instructions below when performing any of the preventive maintenance checks and services.
a. Always keep in mind the WARNINGS and CAUTIONS.
b. Before - These PMCS procedures should be performed each time the equipment is unpacked and during
system setup. It is not necessary to perform the PMCS procedures after each use if the system is not dismantled
and repacked.
c. Weekly - These procedures should be performed on weekly basis.
d. Semiannually - These procedures should be performed every 6 months.
e. Report any malfunctions or failures on DA Form 2404.
2-3. PMCS PROCEDURES.
PRIOR TO PERFORMING THE PMCS PROCEDURES, ENSURE
THAT POWER TO THE SYSTEM IS DISCONNECTED.
