Unit Operation
This diesel locomotive contains a
self-powered smoke unit that outputs
smoke through the smokestack on the roof
of the engine. The smoke unit is essentially
a small heating element and wick that soaks
up and then heats a mineral oil-based fluid
that emits a harmless smoke. The smoke is
then forced out of the stack by a small
electric fan. Smoke volume is controlled
by the Proto-Sound 2.0 system.
With a few easy maintenance steps, you
should enjoy trouble-free smoke unit
operation for years.
When preparing to run this engine, add
15-20 drops of smoke fluid through the
smokestack (see Fig. 2). We recommend
M.T.H. ProtoSmoke, Seuthe, LGB, or
LVTS fluids. Do not overfill the unit or
the fluid may leak out and coat the interior
engine components.
If you choose not to add the fluid (or have
already added the fluid but choose to run
smoke-free), turn off the smoke unit switch
located under the engine (see Fig.
3).
Failure either to add fluid to the unit or to
turn it off may damage the smoke unit
heating element and/or wicking material.
When the smoke output while running the engine begins to diminish, add another 10-15
drops of smoke fluid or turn the smoke unit off.
When storing the unit for long periods of time, you may want to add about 15 drops of
fluid to prevent the wick from drying out.
