TM 5-4320-306-102-9. OPERATION IN EXTREME HEAT (Continued)f. Air Cleaner. High am bent temperatures change density of air used by the engine in combustion. Monitorengine's ability to breathe using the air cleaner intake restriction indicator. Air filter elements should be changed at firstindication of unacceptable restriction of air flow.WARNINGDeath or serious Injury could occur if diesel fuel oil Is not handled carefully. Use In a well-ventilated area away from open flame, arcing equipment, ignition sources, heaters, or excessiveheat. Be certain that fuel lines and connections are secure. Do not Inhale vapor. Do not overfillfuel tank. Engines must be turned off and cooled before fueling. Use proper refueling proceduresand equipment to avoid spillage. Do not run engines near open fuel containers. DO NOT SMOKE.g. Fuel. Fill the fuel tank at the end of each day of operation in order to prevent an accumulation of vapor in thefuel tank. However, do not overfill. Allow room for fuel expansion.h. Batteries. Increase battery PMCS frequency. Use distilled water or a good grade of drinking water I(excluding mineral water) to bring electrolyte to proper level.2-10. OPERATION IN RAINY OR HUMID CONDITIONSWARNING IDeath or serious Injury could occur if diesel fuel oil Is not handled carefully. Use in a well-ventilated area away from open flame, arcing equipment, Ignition sources, heaters, or excessiveheat. Be certain that fuel lines and connections are secure. Do not Inhale vapor. Do not overfillfuel tank. Engines must be turned off and cooled before refueling. Use proper refuelingprocedures and equipment to avoid spillage. Do not run engines near open fuel containers. DONOT SMOKE.a. Check that fuel tank filler cap is tight and gasket is not torn. Fill fuel tank immediately after every operatingperiod to prevent condensation.b. Take special care to prevent rust and corrosion. Coat machined surfaces with oil. Contact organizationalmaintenance to remove any rust or corrosion, and cover the exposed surfaces with paint.2-11. OPERATION IN HIGH ALTITUDESThe centrifugal pump unit will operate normally at elevations up to 9000 feet (2743. 2 ml above sea level. Above 9000feet (2743. 2 ml, the operating efficiency of the engine is reduced. Make sure that engine is operating at peakefficiency.2-12. OPERATION IN SANDY OR DUSTY AREASThe engine cover of the pump unit is designed to protect the engine during periods of blowing sand. When operating thepump unit in this type of environment, observe the following precautions.a. Protect the unit from blowing sand and dust as much as possible.Change 2 2-66
