2-8
OPERATION IN EXTREME COLD (CONT).
c.
Fan Belt. Check that the fan belt is property adjusted and drives the cooling fan without slipping.
Contact unit maintenance if fan belt needs to be serviced.
d.
Batteries. Increase battery PMCS frequency. Use distilled water or a good grade of drinking water
(excluding mineral water).
2-10 OPERATION IN RAINY OR HUMID CONDITIONS.
WARNING
Death or serious injury could occur if diesel fuel is not handled carefully. Use in a
well-ventilated area away from open flame, arcing equipment, ignition sources,
heaters, or excessive heat. Be certain that fuel lines and connections are secure.
Do not inhale vapor. Do not overfill fuel tank. Engine must be turned off and
cooled before refueling. Use proper refueling procedures and equipment to avoid
spillage. Do not run engine near open fuel containers. DO NOT SMOKE.
a.
Check that valve inside filler cap is open, fuel tank filler cap is tight, and gasket is not torn. Fill fuel
tank immediately after every operating period to prevent condensation.
b.
Take special care to prevent rust and corrosion. Coat machined surfaces with oil. Remove any
rust or corrosion, and cover the exposed surfaces with paint.
2-11 OPERATION IN HIGH ALTITUDES. The mainline pumping assembly will operate normally at elevations
up to 9000 feet (2743.2 m) above sea level. Above 9000 feet (2743.2 m), the operating efficiency of the
engine is reduced approximately 4 percent for every 1000 feet. Total discharge head will be reduced, and
allowance will have to be made in the placement of booster pump stations and pressure regulators by the
pipeline design to account for the increase in altitude.
2-12 OPERATION IN SANDY OR DUSTY AREAS. The pumping assembly's doors and covers are designed
to protect the engine during periods of blowing sand. When operating the pump unit in this type of
environment, observe the following precautions.
a.
Protect the unit from blowing sand and dust as much as possible.
CAUTION
Closely monitor air cleaner intake restriction indicator in sandy or dusty locations.
At first sign of restriction, change filter elements. Inadequate air filtering and
excessive restrictions to air and exhaust flows will adversely affect turbo- charger
life and performance.
b.
Frequently check the air cleaner restriction indicator. If red band appears in window of air cleaner
restriction indicator and no damage to system components is found, contact unit maintenance.
c.
Frequently check oil to be sure it is not contaminated. Contact unit maintenance if oil is
contaminated.
WARNING
Death or serious injury could occur if diesel fuel is not handled carefully. Use in a
well-ventilated area away from open flame, arcing equipment, ignition sources,
heaters, or excessive heat. Be certain that fuel lines and connections are secure.
Do not inhale vapor. Do not overfill fuel tank. Engine must be turned off and
cooled before refueling. Use proper refueling procedures and equipment to avoid
