. What is necessary to do this?

A. Take a monkey wrench and screw the inner sleeve down to the right to
reduce the lift, and to the left to increase the lift. In reducing the
lift you reduce the speed, and by increasing the lift you increase the
speed.

10. Q. Is there any other method of setting speed?

A. Yes.

11. Q. How?

A. By removing oil box on the turbine cap and adjusting the nuts on the
governor studs on the face of wheel.

12. Q. Is any provision made for operating the light with low pressure
steam?

A. Yes.

13. Q. What?

A. An auxiliary valve is used which operates automatically at any
predetermined pressure, which is adjusted by an adjusting stem at the
bottom of the engine and which can also be adjusted while the light is
burning.

14. Q. What kind of oil should be used in the "Buda-Ross" bearings?

A. Cylinder or valve oil.

15. Q. What style of generator is used.

A. An iron-clad type with no outside magnetism.

16. Q. How many fields in this generator?

A. Two.

17. Q. What style field is used?

A. Compound wound.

18. Q. What kind of wire is used on these fields?

A. Deltabeston wire.

19. Q. Why is Deltabeston wire used in preference to cotton-covered
wire?

A. So that it cannot be injured by short circuits, for if a short
circuit occurs and afterwards is removed there is no danger done to the
insulation on this make of wire.

20. Q. Where are the fields located?

A. One on each side of the dynamo.

21. Q. Why?

A. So that they cannot be injured by waste oil from the ball bearing, or
by water or snow.

22. Q. How should ball bearing on dynamo end be lubricated?

A. By removing oil plug in frame just back of dynamo and introducing
cylinder oil.

23. Q. Is it necessary to remove the top carbon holder from the lamp to
remove reflector from case?

A. No.

24. Q. Why not?

A. Because there is no top guide to the carbon, as the carbon is guided
by the clutches.

25. Q. How many levers are there in the lamp?

A. Only one.

26. Q. What regulation should be given to top lever spring No. 308 on
lamp?

A. Top lever spring No. 308 should be adjusted as loose as possible and
not have light go out standing still.

27. Q. If this spring was tightened until the light burned steady when
the locomotive was at rest, what might occur when engine was running
high speed?

A. It might cause the light to dim down.

28. Q. Is there anything else that would cause the
