again. At this point, the engine will now function just like any other
electronic or mechanical E-unit.
PROTOSMOKE™ UNIT OPERATION
The F59PH contains a self-powered smoke unit that outputs a steady stream of smoke
through the smoke stack on the roof of the engine. The ON/OFF switch located next to the
power truck must be in the ON position in order for the smoke unit to function. See Fig. 1b on
page 3.
The smoke unit is essentially a small heating element and wick which soaks up and then
“cooks" a mineral oil-based fluid that omits a harmless smoke. The smoke is then forced out
of the stack via a small electric fan which runs at a constant speed. However, the smoke
intensity can be varied by increasing the transformer voltage setting. The higher the setting,
the more intense the smoke output.
For best results, we recommend that you add 20 - 25 drops of ProtoSmoke™, Seuthe, LGB or
LVTS fluid before you run the engine. If you don’t choose to add the fluid, then the smoke
unit switch should be turned off. Failure to either add the fluid or turn the switch off could
lead to damage to the smoke unit heating element and or wicking. Add the fluid through the
smoke stack hole. After adding the fluid, gently blow into the stack to eliminate any air
bubbles. Do not overfill the unit as overfilling can cause the fluid to leak out and coat the
interior engine components. When the smoke output begins to diminish while running the
engine, an additional 20-25 drops of smoke fluid should be added or the smoke unit switch
should be turned off. When storing the engine for long periods of time, you may want to add at
least 20 drops of fluid to keep the wick soaked with fluid and prevent it from drying out. After
removing the engine from storage, it is
advisable to add another 25 drops of fluid,
letting the wick soak up the fluid for 15
minutes prior to operation.

MAINTENANCE
CAUTION: Operating the engine without
smoke fluid and with the smoke unit switch
in the ON position can damage your smoke
unit wick, causing the wick to become hard,
blackened and unabsorbant around the
heating element. When this occurs, it may
be difficult for the wick to soak up the
smoke fluid resulting in poor or no smoke
output. If that occurs, we recommend that
you inspect and/or replace the wick taking
care to not run the engine without fluid in
the future. You can inspect the wick to see
if it needs replacement by removing the
smoke unit circuit board from the smoke unit body as seen in Fig.3. After removing the circuit
board screws lift the circuit board away and inspect the wick. If the wick is darkly discolored
and hard, it should be replaced.
