ProtoSmoke® Unit Operation
This Premier steam 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. 12). 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 tender floor (see
Fig. 13). Failure either to add fluid to the unit or to turn it off may damage the
smoke unit heating element and/or wick 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.

Locking Locomotive Into A Direction
Reset To Factory Default
Automatic Sound Effects
You can lock your engine into a direction (forward, neutral, or reverse) so that it
will not change directions. To do this, put the engine into the direction you want
(or into neutral to lock it into neutral), run it at a very slow crawl (as slowly as it will
move without halting), and quickly but firmly tap the Horn button once followed
by three quick taps of the Bell button, allowing approximately ½ second to lapse
between each quick button press. Two horn blasts will indicate that the engine has
made the change. The engine will not change direction (including going into
neutral) until you repeat the 1 horn, 3 bells code to return the engine to its normal
condition, even if the engine is kept without power for extended periods of time.
To override the settings you currently have assigned to the engine and reset it to its
factory defaults, while in Neutral tap the Horn button quickly once, followed by
five quick taps of the Bell button, allowing approximately ½ second to lapse
between each quick button press. Two horn blasts will indicate that the engine has
made the change.
Certain Proto-Sound 2.0 sound effects automatically play in programmed
conventional mode conditions:
•Squealing Brakes play any time the engine's speed decreases rapidly.
•Cab Chatter plays at random intervals when the engine idles in neutral.
•Engine Start-up and Shut-down sounds play when the engine is initially
powered on or is powered off for five seconds or more.
