b.
Assembly of Equipment. Some pump and engine assemblies do not have cam-lock fittings on the suction
or discharge ports of the pump. If the pump and engine assembly furnished with the FAWPSS does not have these
cam-lock fittings. perform the following procedures.
(1)
Apply sealing compound (Appendix F, Item 4) to male threads of discharge outlet pipe of pump and
engine assembly and install male cam-lock fitting (Appendix D, Item 22) to outlet pipe of pump.
(2)
Apply sealing compound (Appendix F, Item 4) to male threads of suction inlet pipe of pump and
engine assembly and install female cam-lock fitting (Appendix D, Item 24) to inlet pipe of pump.
(3)
Attach quick disconnect plugs (Appendix D. Item 25) to nozzle assemblies (Appendix D. Item 4)
with retaining rings (Appendix D, Item 11).
For all other FAWPSS assembly instructions refer to paragraph 2-7.
Section III. UNIT PREVENTIVE MAINTENANCE CHECKS AND SERVICES
4-7. INTRODUCTION.
a.
Systematic, periodic, Preventive Maintenance Checks and Services (PMCS) are essential to ensure that
the FAWPSS is ready for operation at all times. The purpose of a preventive maintenance program is to discover
and correct defects and deficiencies before they can cause serious damage or complete failure of the equipment.
Any effective preventive maintenance program must begin with the training of operators to report all unusual
conditions noted during daily checks or actual operation to unit maintenance. All defects and deficiencies
discovered during maintenance inspections must be recorded, together with corrective action taken, on DA Form
2404 (Equipment Inspection and Maintenance Worksheet).
b.
A schedule for unit preventive maintenance inspection and service should be established immediately
after installation of the FAWPSS. A quarterly interval, equal to three calendar months or 250 hours of operation
(which ever occurs first) is recommended for usual operating conditions. When operating under unusual
conditions, such as a very dusty or sandy environment, it may be necessary to reduce the interval to monthly or
even less if conditions are extreme.
4-8.
UNIT PMCS. The FAWPSS has no system unit PMCS. However, the pump and engine assembly and
collapsible storage drums do have unit PMCS. Refer to the applicable technical manual for these items for proper
unit PMCS procedures and perform those procedures.
