be done?

A. Shut stoker off by throwing operating rod on back head of locomotive
boiler out of running position.

16. Q. When train is to stand for a long time or engine is left at
terminal, what should be done?

A. The driving engine should be cut out entirely by closing main steam
line inlet and main lubricator connection, and in winter time all drain
cocks should be opened.

17. Q. If sufficient coal can not be supplied over front grates, what
may be the cause?

A. Distributors may be warped and point too low, or steam jets may be
plugged with pipe scale and not blowing freely.

18. Q. How would you start and operate stoker?

A. First open main valve No. 1 at steam turret. Valve 2 is then opened;
this is the main valve in stoker steam line. Next open valve 3, which
allows the steam to flow to the distributor jet line; open valves 4 and
5, which govern the pressure on the jets until ten pound pressure shows
on the right-hand gauge. See valve 8 to the exhaust line is open, and
valve 9 to the transfer hopper is closed.

19. Q. How would you start the stoker engine?

A. Place operating lever 10 in horizontal or running position. Place
conveyor reversing lever 12 in forward position. Open valve 6, which
allows the steam to pass to the operating valve and starts stoker
running. Valve 7 is to be used as an emergency valve only in case of
clogging. Stoker should be run slowly at first. Do not feed too much
coal and carry a light fire.

20. Q. How would you reverse conveyor screw in tank?

A. Lower handle 10 on operation rod on boiler head to bottom position.
Move screw conveyor, reverse lever 12 back to rear or reverse position,
raise handle 10 on operating rod to center position.

21. Q. How would you stop conveyor screw in tank?

A. Place conveyor reversing lever 12 in center position.

22. Q. How would you reverse right or left elevator screw?

A. Raise elevator pawl shifter 26 on top of the vertical shaft to upper
position.

23. Q. How would you stop right or left elevator screw?

A. Raise elevator pawl shifter 26 on top of the elevator to middle
position.

24. Q. How would you locate clogs in case the stoker stalls?

A. First, shut off pressure to stoker engine cylinder by closing valve
6. Second, move operating valve lever 10 to its lowest position. Third,
place tender conveyor reverse lever 12 in center. Fourth, place right
elevator pawl shifter 26 in neutral position. Fifth, raise operati
