TM 5-3895-373-201.15.2.ScreedBurnerFuelSystem.Thescreed burner fuel system consists of fuel tank, fuel filter,fuel pump assembly, manual shutoff valve, twomanifolds, four solenoid valves, and four screed burners.The fuel filter has one input and one output. The filterremoves impurities from the fuel supply by passing thefuel through a filter. From the filter, the fuel is sent to afuel pump assembly.The fuel pump assembly consists of an electric motorshaft coupled to a single stage pump. The motor iscontrolled from the left screed control panel. The pumphas a continuous output of 7 gph (26 V/hr).From the fuel pump, fuel is supplied to a manifoldthrough a manual shutoff valve.The right hand manifold is a divider with one input andthree outputs. One output is the input to the left handmanifold. The remaining two outputs are to the screedburners on the right side of the screed. The left handmanifold has one output usedby the spray wand assembly and two outputs for thescreed burners on the left side of the screed.Electrical solenoid valves control the flow of fuel from themanifolds to the burners. These valves are controlled byseparate switches on the screed control panels. Thisallows for independent burner operation.1.15.3. WashdownSprayAssemblyFuelSystem.The washdown spray assembly fuel system consists offuel tank, fuel filter, fuel pump assembly, manual shutoffvalve, two manifolds, four solenoid valves, and spraywand assembly. The fuel pump that draws fuel to thescreed burners also provides fuel for the spraywashdown system.The spray wand assembly consists of a 10 ft (3 m) quickdisconnect hose, fitting, and a triggertype control wand.The spray wand assembly is primarily used to spray fuelon components that are directly exposed to pavingmaterial. This prevents paving material from sticking,and allows the material to be removed from machinecomponents by scraping or other mechanical means.1-19
