Rail King UNION PACIFIC 4-6-2 49er Operating Instructions Manual

4RailKing U.P. 49er Operating ManualRAILKINGPROTOSMOKE™ UNIT OPERATIONThe U.P. 49er contains a self-powered smoke unit that outputs a steady stream of smokethrough the smoke stack on the roof of the engine. The ON/OFF switch located next to thetrailing truck must be in the ON position in order for the smoke unit to function. See Fig. 3below.The smoke unit is essentially a small heatingelement and wick which soaks up and then cooks" amineral oil-based fluid that omits a harmless smoke.The smoke is then forced out of the stack via a smallelectric fan which runs at a constant speed. However,the smoke intensity can be varied by increasing thetransformer voltage setting. The higher the setting,the more intense the smoke output.For best results, we recommend that you add 15 -20 drops of ProtoSmoke, Seuthe, LGB or LVTSfluid before you run the engine. If you dont chooseto add the fluid, then the smoke unit switch shouldbe turned off. Failure to either add the fluid or turn the switch off could lead to damage to thesmoke unit heating element and or wicking. Add the fluid through the smoke stack hole. Afteradding the fluid, gently blow into the stack to eliminate any air bubbles. Do not overfill theunit as overfilling can cause the fluid to leak out and coat the interior engine components.When the smoke output begins to diminish while running the engine, an additional 10-15drops of smoke fluid should be added or the smoke unit switch should be turned off. Whenstoring the engine for long periods of time, you may want to add at least 15 drops of fluid tokeep the wick soaked with fluid and prevent it from drying out. After removing the enginefrom storage, it is advisable to add another 25 drops of fluid, letting the wick soak up the fluidfor 15 minutes prior to operation.MAINTENANCECAUTION: Operating the engine without smoke fluidand with the smoke unit switch in the ON position candamage your smoke unit wick, causing the wick tobecome hard, blackened and unabsorbant around theheating element. When this occurs, it may be difficultfor the wick to soak up the smoke fluid resulting in pooror no smoke output. If that occurs, we recommend thatyou inspect and/or replace the wick taking care to notrun the engine without fluid in the future. You caninspect the wick to see if it needs replacement byremoving the smoke unit inspection cover from the bodyas seen in Fig.4. After removing the chassis andinspection cover screws lift the inspection plate awayand inspect the wick. If the wick is darkly discoloredand hard, it should be replaced.Smoke Unit SwitchFigure 3: Smoke Unit SwitchSmoke UnitCircuit BoardMounting ScrewsSmoke Unit FrameMounting ScrewsFigure 4: Inspecting The Smoke Unit
