7. Q. How should the stoker be oiled and operated?

A. It should be thoroughly oiled before leaving the terminal, then see

that operating rod on back head is in center or running position, open

main jet line so they register about fifteen pounds on the jet steam

gauge if coal is coarse, or ten pounds if coal is small. Next, the

driving engine steam valve should be opened wide and the throttle valve

opened just enough to supply the proper amount of coal to the fire-box.
