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. 10). 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. 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.
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.
If you experience poor or no smoke
output when the smoke unit is on and
has fluid, check the wick to see if it has
become hard, blackened, and
unabsorbent around the heating element.
After removing the locomotive body
from its chassis (See Figure 5), remove
the smoke unit inspection cover (see
Fig. 11). After removing the inspection
cover screws, lift the inspection plate
away and inspect the wick. If it is
darkly discolored and hard, it should be
replaced.
Replacement parts and wick
replacement instructions are available directly from the M.T.H. Parts Department (order
