Section V. PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
4-9. GENERAL. To ensure that the equipment is ready for operation at all times, it must be inspected systematically so
that defects may be discovered and corrected before they result in serious damage or failure. This section contains
information pertinent to organizational maintenance. Table 4-2 contains a tabulated listing of preventive maintenance
checks and services which must be performed by organizational maintenance personnel at weekly, monthly and
Section VI. TROUBLESHOOTING
a. Table 4-3 contains troubleshooting information for locating and correcting operating troubles which may develop in
the generator set. Each malfunction for an individual component unit, or system, is followed by a list of tests or
inspections which will help you to determine probable causes and corrective actions to take. Perform the tests,
inspections, and corrective actions in the order listed.
b. This manual cannot list all malfunctions that may occur, nor all tests or inspections and corrective actions. If a
malfunction cannot be corrected by listed corrective actions, notify your supervisor.
Section VII. RADIO INTERFERENCE SUPPRESSION
4-11. GENERAL METHODS USED TO ATTAIN PROPER SUPPRESSION. Essentially suppression is attained by
providing a low resistance path to ground for stray currents. The methods used include shielding the wires, grounding the
frame with bonding straps, and using filtering systems.
4-12. INTERFERENCE SUPPRESSION COMPONENTS.
Primary Suppression Components. The primary suppression components are those whose function is to
suppress radio interference. The voltage regulator contains an electromagnetic interference (EMI) suppression
assembly to suppress EMI from this assembly
Secondary Suppression Components. These components have radio suppression functions which are incidental
or secondary to their primary function. No secondary suppression components are included in this generator set.
