® By MTH Electric Trains RAILKING GS-4 STEAM ENGINE OPERATING INSTRUCTIONS Thank you for purchasing the RailKing die-cast Gs-4 steam locomotive. The engine’s die-cast body and tender are traditionally sized for operation on any O-27 or larger layout. The engine is compatible with any standard AC transformer and is completely compatible with most other 3-rail locomotives, rolling stock and accessories.
QUICK START - BASIC OPERATION The RailKing Gs-4 contains state-of-the art electronics for incredibly realistic operation. Despite these advanced features, the Gs-4 is easy to operate with any compatible standard AC transformer. All models are equipped with an operating smoke system that should be primed with smoke fluid before operating.
SMOKE UNIT MAINTENANCE CAUTION: Operating the engine without smoke fluid and with the smoke unit switch in the ON position can damage your smoke unit wick, causing the wick to become hard, blackened and unabsorbant around the heating RailKing Gs-4 Operating Manual...
