A. No.
5. Q. If the light is properly focused, that is, if the rays are leaving the reflector in parallel lines, but the light does not strike the center of the track, what should be done?
A. When the light rays are thrown out in parallel lines and they do not strike the center of the track, it denotes that the headlight case is not set straight with the engine, and the entire case on base board must be shifted until the shaft of light strikes the track as desired.
6. Q. What can you do to insure a good and unfailing light for the entire trip?
A. By carefully inspecting the entire equipment before departing on each trip, and know that there are no wires with insulation charred or worn off, that all screws and connections are tight, commutator clean and brushes set in brush holder in proper manner. Carbon in lamp of sufficient length to complete trip, and that the carbon will feed through the clutch freely and rests central over the copper electrode. Copper electrode cleaned off, oil in both bearings and see that steam does not blow at stuffing box gland.
7. Q. What kind of oil and how much would you use in the bearings of the electric headlight equipment?
A. Would use the best grade of black or engine oil furnished for both bearings and only enough oil in oil cellar that the revolving loose oil ring may trail through the oil. When bearings are supplied with oil cups, use a heavy oil such as good engine or valve oil.
8. Q. Why should you not use valve oil in these bearings?
A. Valve oil cannot be used successfully in the main bearing because of its heavy body. Valve oil could not be carried up to shaft by the oil ring in cold weather, as the ring will not revolve.
