SMOKE UNIT OPERATION
The Dreyfuss contains a self-powered smoke unit that outputs a steady stream of smoke
through the smoke stack. The ON/OFF switch located under the right side of the locomotive
cab must be in the ON position in order for the smoke unit to function. See Fig. 2.

The smoke unit is essentially a small
heating element and wick which soaks up
and then “cooks" a mineral oil-based fluid
that omits a harmless smoke. The smoke
is then forced out of the stack via a small
electric fan which runs at a constant
speed. However, the smoke intensity can
be varied by increasing the transformer
voltage setting. The higher the setting,
the more intense the smoke output.
For best results,
we recommend that you add 15 - 20 drops of Seuthe, LGB or LVTS fluid
before you run the engine. If you don’t
choose to add the fluid, then the smoke
unit switch should be turned off.
Failure to
either add the fluid or turn the switch off could
lead to damage to the smoke unit heating
element and or wicking. Add the fluid through
the smoke stack hole as indicated in Figure 3.
After adding the fluid, gently blow into the stack
to eliminate any air bubbles. Do not overfill the
unit as overfilling can cause the fluid to leak out
and coat the interior engine components.
When the smoke output begins to diminish
while running the engine, an additional 10-15
drops of smoke fluid should be added or the smoke unit switch should be turned off.
Figure 3: Adding Smoke Fluid
When storing the engine for long periods of time, you may want to add at least 15 drops of
fluid to keep the wick soaked with fluid and prevent it from drying out. After removing the
engine from storage, it is advisable to add another 25 drops of fluid, letting the wick soak up
the fluid for 15 minutes prior to operation.
SMOKE UNIT MAINTENANCE
CAUTION:
Operating the engine without smoke fluid and with the smoke unit switch in the
ON position can damage your smoke unit wick, causing the wick to become hard,
blackened and unabsorbant around the heating element. When this occurs, it may be
difficult for the wick to soak up the smoke fluid resulting in poor or no smoke output. If that
