In Figs. 102 and 103 is shown the plan of operation of a powerplant oil filter with the various parts named. Starting the Engine. Before starting an engine, the oil cupsshould be started feeding, grease cups screwed down, and the gov- STEAM ENGINES 171 ernor and other parts of the valve gear oiled. The cyhnder lubri-cator should be started before the engine so that the oil passageswill contain oil. The cylinder drain cocks should be open so thatany condensed steam in the cylinder will be removed withoutinjury to the cylinder. These precautions having been observed, © © ® ® Fig. 102. Drawing Showiug Interior Construction of Power Plant OilFilter. (See List of Parts under Fig. 103) the throttle may be opened slowly and the engine started andgradually brought to the required speed. After starting the engine, notice should be taken of the gover-nor and all the lubricating apparatus to see that each is properlyperforming its function. When the engine is to operate condensing, the condensershould be started first, if it is in such a position that the water 172 STEAM ENGINES in the exhaust can drain into it. If the condenser is abovethe engine and no means are provided for removing the water, theengine should be started non-condensing. When a jet condenseris used, the quantity of injection water should be increased as theload is increased; the amount being determined by the conditionsof the vacuum and temperature of the discharge water, which
