TM 55-2210-223-12TO 45A2-2-14-412-33. 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 orchecking fuel level.(2)Clean engine air cleaner and breather caps daily, or more often, in extremely dusty condition.(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 CONDITIONSa.Lubrication. Refer to LO 55-2210-223-12. 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 andfree of dirt accumulation.c.Electrical System. High humidity tends to increase corrosion of battery terminals and cause electrical leakageacross top of batteries. Keep terminals well coated with grease (item 5, app E). Keep top and side of batteriesclean and dry.d.Fuel System. High humidity accelerates condensation of water in fuel tanks. Condensation can be kept to aminimum 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 fueltank. Have unit maintenance personnel service fuel filters frequently to remove collected water.e.Clean and spot paint rusted areas of locomotive.2-35. OPERATION IN SALTWATER AREASCorrosion of metal is greatly accelerated in saltwater areas. Humid salt atmosphere also damages electricalcomponents. 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 fuelfilters frequently to remove collected water. Service engine air cleaner frequently.c.Electrical System. Keep electrical components clean and dry. Clean battery tops frequently. Inspect terminals,connectors, and switches frequently and clean off moisture. Keep battery terminals well coated with grease (item5, app E).2-49
