Back to basics.TAKING CARE OF COMBAT VEHICLE IN HOT, DUSTY OR SANDY CONDITIONS TAKES A LOT OF EXTRA EFFORT THAT MEANS GOING BACK TO THE BASICS OF PM. Clean Air Make sure your air induction system is in good shape. That includes hoses, inlets, outlets, precleaners, and filter elements. Cracks, tears, holes and loose clamps let sand and dust get into engines. Clean air filters often Pay attention to air restriction indicators. Clean air filter elements as often as necessary to keep engine performance high. Park your vehicle with the engine compartment downwind down·wind adv. In the direction in which the wind blows. down  wind . That allows the bulk of the vehicle to shield the engine from blowing sand or dust. Keep all air-cooled surfaces--oil coolers and radiators--free of oil and grease. These surfaces transfer heat away from the oil and water inside as air flows past them. Oil and grease attract dust and sand like magnets. The heat can't escape, so engine and transmission damage are the result. I CAN HANDLE THE HEAT AND SAND ... IF YOU'LL HANDLE MY PM! Keep engine compartment downwind Keep oil coolers clean Clean Fuel It's critical to keep fuel clean during refueling. Always wipe off the nozzle An orifice in an inkjet print head through which ink is sprayed onto the paper. Print heads with six thousand or more nozzles are common in today's printers. Nozzle before refueling. If you suspect there's dirt inside the nozzle, flush it out or take the nozzle off and clean it. Keep the fuel nozzle capped when it's not in use. Blow away loose dust and sand from the vehicle's fuel filler fill·er 1 n. One that fills, as: a. Something added to augment weight or size or fill space. b. A composition, especially a semisolid that hardens on drying, used to fill pores, cracks, or holes in wood, plaster, opening before removing the cap. When the fuel nozzle is in place, use a clean rag to close off any gaps between the nozzle and the fuel filler opening. That keeps blowing sand and dust from getting into the fuel tank. Close the fuel cap tight when you're finished. No matter how careful you are, some dirt is going to get into the fuel system. That means draining the fuel filters to keep 'em from clogging. Draining the fuel filters also gets rid of condensation that results from cool nights and hot days. You may need to drain fuel tilters more than once a day to keep engine performance high, but they should always be drained at least once a day to keep water from diluting the fuel. Use only clean water from a reliable source for filling radiators. Local water supplies often contain mineral deposits that will eventually clog up radiator radiator, device used to heat an area surrounding it or to cool a fluid circulating within it. The familiar radiators of steam and hot water heating systems in buildings are misnamed, as they operate principally by convection, in which heat is transferred by air cores. If local water must be used, filter it through a clean cloth before adding it to a radiator. Then, clean and purge To eliminate or delete. the radiator at the next opportunity. Blow away dust and sand before opening fuel cap Drain fuel filters at least daily MAYBE I'D BETTER FILTER THIS WATER FIRST! MAYBE YOU'D BETTER Track Maintenance Check the drive sprocket assembly, road-wheel mounting bolts, end connector bolts, track pin nuts, and centerguide bolts before, during and after operation. Sand, rocks and gravel tend to break or damage lube fittings and relief valves. Rough terrain causes hardware to work loose. Never neutral steer in soft sand. That lets sand build up in the track assembly components and can result in a thrown track. Make fast turns wide. Keep short turns slow. Pay attention to the tracks during at-halt inspections. Check track tension. Look for cracked end connectors and broken track pins. Since you'll be lubing bearings much more often in sandy and dusty conditions. make sure you wipe away any excess lube when you're finished. Grease attracts sand, and the two combined can grind away Verb 1. grind away - study intensively, as before an exam; "I had to bone up on my Latin verbs before the final exam" bone, bone up, mug up, swot, swot up, cram, drum, get up cram - prepare (students) hastily for an impending exam metal. Optics Care Cover glass surfaces when they're not being used. Scouring scouring characterized by scour. scouring disease a colloquial name for secondary nutritional copper deficiency. and etching etching, the art of engraving with acid on metal; also the print taken from the metal plate so engraved. In hard-ground etching the plate, usually of copper or zinc, is given a thin coating or ground of acid-resistant resin. by sand and dust will ruin them. That's especially true for sighting and fire control equipment. The buildup build·up also build-up n. 1. The act or process of amassing or increasing: a military buildup; a buildup of tension during the strike. 2. of dust on these surfaces can also degrade TO DEGRADE, DEGRADING. To, sink or lower a person in the estimation of the public. 2. As a man's character is of great importance to him, and it is his interest to retain the good opinion of all mankind, when he is a witness, he cannot be compelled to disclose low-light vision. So keep surfaces as clean as possible using the specific cleaners called out in your TMs. Optical lens cleaning compound, NSN NSN National Stock Number NSN Nokia Siemens Networks NSN National Storytelling Network NSN NATO Stock Number NSN New Substances Notification (CEPA) NSN National Student Number (NZ) NSN Never Say Never 6850-00-227-1887, can be used if your TM does not list one. During dust or sandstorms, you might want to use sell-clinging plastic film to cover optics between missions. NSN 8135-00-043-5331 gets a 100-ft roll of 11 1/2-in wide film.
