Operation in Salt Water Areas - TM-5-4320-243-150080

2-18. Operation in Salt Water Areas

a. General. Salt water has a corrosive action on

metal. Extreme care must be taken to prevent rust from

forming on the unit. The electrical insulation should be

inspected frequently for deterioration.

b. Cooling System. Use fresh water only for the

cooling system. Salt water may damage the equipment.

Use an approved rust inhibitor to prevent the formation

of rust and scale in the cooling system.

c. Lubrication. Keep the centrifugal pump well

lubricated to prevent salt and moisture from entering the

engine. Refer to the current lubrication order (fig. 3-1).

d. Rust Prevention. Wash down the unit regularly

with fresh water. Inspect all painted surfaces for

cracked, peeled, or blistered paint. Coat all exposed

surfaces with rustproofing paint. Report the condition to

organizational maintenance.

2-19. Operation at High Altitude

The centrifugal pump is designed to operate at altitudes

up to 5,000 feet above sea level without any special

attention or adjustments. At higher altitudes, provide

adequate ventilation as the engine is more likely to

overheat. Adjust the carburetor (para 3-40) before

operation.
