Unit Operation
This Premier 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. This applies only to
the front smoke stack. Do not add fluid to
the rear smokestack.
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.
