ProtoSmoke™ Unit Operation
This diesel locomotive contains a smoke unit that outputs smoke through the exhaust
stack(s) 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. With a few easy
maintenance steps, you should enjoy trouble-free smoke unit operation for years.
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.
After removing the engine from storage, add another 25 drops of fluid, letting the wick
soak up the fluid for 15 minutes prior to operation.

unit may cause damage
When preparing to run this engine, add
15-20 drops of smoke fluid through the
smokestack. We recommend M.T.H.
ProtoSmoke fluid (a small pipette of
ProtoSmoke fluid is included). 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
control by turning to full counter clockwise
position).
Failure either to add fluid to
the unit or to turn it off may damage
the smoke unit heating element and/or
wicking material.
