Sufficient time should be allowed for the condenserand sight feed glasses to fill with water. Water-valve Dshould be opened immediately after the steam valve isopened.

When refilling the lubricator, valves EE and L shouldalways be closed before closing water-valve D. Drainplug G should be opened, and filling plug O removed. The lubricator should be blown out at least once aweek, or oftener when necessary. In getting a new or a rebuilt locomotive ready forservice, the oil pipes should be disconnected at thesteam-chest, and the oil pipes and automatic steam-chest valves blown out thoroughly.
