F-3 A B A DIESEL ENGINE SET
This engine contains a smoke unit that outputs smoke through the
smokestack on 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.
W ith 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 figure 5) W e recommend M.T.H. ProtoSmoke,
Seuth, LGB, or LVTS fluids (a small pipette of
ProtoSmoke fluid is included). Do not over fill 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 body.
(see figure 6) Failure to either
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 begins to
diminish, add another 10-15 drops of smoke fluid
or turn the smoke unit off
.
When storing the unit for extended 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
unabsorbant around the heating element. Remove
the smoke unit inspection cover from the smoke unit s body.
(see figure 7) After remov-
ing the
inspection cover screws, lift the inspection plate away and inspect the wick. If it is
darkly discolored and hard, it should be replaced.
