(6) Start engine carefully with cylindercocks open until dry steam appears. Instarting the reverse lever should be infull gear to insure oil distribution the fulllength of the valve bushings. (c) Keep water level as low as in satu-rated steam locomotives. Actual testsWith a pyrometer show that the tem-perature is 40° higher with two gaugesof water than with three. id) The man who carries the boileron a superheater locomotive full of water,is using the superheater units for a boilerto boil water and not to superheat steam;. CUT No. 2 CONNECTION TOSTEAM CHEST therefore the engine will not steam as well,as these superheater units with properoperation add 25 per cent, greater capacityto the bciler. (e) Do not close the throttle entirely ona superheater locomotive; leave thethrottle cracked enough to keep steam inthe steam chests and cylinders whiledrifting, unless equipped with a driftingvalve. If equipped with a drifting valve,open drifting valve before throttle isclosed. Also be sure the reverse lever isdropped as far down as possible whiledrifting, as tests have demonstrated thatthe superheater damper valve will notclose in short cut-off. It is necessary todrop the bar to full stroke while driftingin crder to relieve the steam in steamchest to close the superheater damper.
