2-33. OPERATION IN DUSTY OR SANDY AREAS (cont)
c. Fuel System.
(1) Keep fuel tank filler cap securely tightened. Wipe dirt from cap and surrounding area before filling or
checking fuel level.
(2) Clean engine air cleaner and breather caps daily, or more often, in extremely dusty conditions.
(3) If refueling is required, use a fine wire mesh or a piece of lint-free cloth to screen out impurities.
2-34. OPERATION IN RAINY OR HUMID CONDITIONS
a. Lubrication. Refer to LO 55-2210-224-12. Be sure to clean grease fitting prior to lubricating.
b. Cooling System. Normally, rain and high humidity tend to increase efficiency of a cooling system. However,
high humidity may accelerate accumulation of dirt and debris on cooling surfaces of radiator. Keep clean and
free of dirt accumulation.
c. Electrical System. High humidity tends to increase corrosion of battery terminals and cause electrical leakage
across top of batteries. Keep terminals well coated with petrolatum (item 19, app E). Keep tops and sides of
batteries clean and dry.
d. Fuel System. High humidity accelerates condensation of water in fuel tanks. Condensation can be kept to a
minimum by keeping fuel tanks filled at all times when locomotive is not in operation. Fill fuel tank daily,
immediately after operation. Wait 2 to 5 minutes for fuel to settle, then drain any accumulated water from fuel
tank. Have unit maintenance personnel service fuel filters frequently to remove collected water.
e. Locomotive Body. Clean and spot paint rusted areas of locomotive.
2-35. OPERATION IN SALTWATER AREAS
Corrosion of metal is greatly accelerated in saltwater areas. Humid, salty atmosphere also damages
electrical components. In these areas, the following procedures must be observed:
a. Bare Metal Surfaces. Keep exposed metal surfaces painted. Coat exposed wear areas, such as cylinder rods,
with lubricating oil, grease, or preservative compound, when not in use. Follow lubrication procedures
regularly. Clean and spot paint rusted areas on locomotive.
b. Fuel System. Keep fuel tanks full when locomotive is not in use. Have unit maintenance personnel service fuel
filters frequently to remove collected water. Service engine air cleaner frequently.
