TM 10-4320-346-12&Pb.AssemblyofEquipment. Some pump and engine assemblies do not have cam-lock fittings on the suctionor discharge ports of the pump. If the pump and engine assembly furnished with the FAWPSS does nothave thesecam-lock fittings. perform the following procedures.(1)Apply sealing compound (Appendix F, Item 4) to male threads of discharge outlet pipe of pump andengine 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 andengine 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 SERVICES4-7. INTRODUCTION.a.Systematic, periodic, Preventive Maintenance Checks and Services (PMCS) are essential to ensure thatthe FAWPSS is ready for operation at all times. The purpose of a preventive maintenance program is to discoverand 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 unusualconditions noted during daily checks or actual operation to unit maintenance. All defects and deficienciesdiscovered during maintenance inspections must be recorded, together with corrective action taken, on DA Form2404 (Equipment Inspection and Maintenance Worksheet).b.A schedule for unit preventive maintenance inspection and service should be established immediatelyafter 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 unusualconditions, such as a very dusty or sandy environment, it may be necessary to reduce the interval to monthly oreven less if conditions are extreme.4-8.UNIT PMCS. The FAWPSS has no system unit PMCS. However, the pump and engine assembly andcollapsible storage drums do have unit PMCS. Refer to the applicable technical manual for these items for properunit PMCS procedures and perform those procedures.Change 14-3
