MTH DL-110 Operating Instructions
PROTOSMOKE™ UNIT OPERATION
The DL-110 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. 1 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

off for three or more seconds. NEUTRAL should be referred to as the
state between Forward and Reverse.
Because the ProtoSound® system or DCRU® reverse unit found in
your powered MTH DL-109 A unit is not directly connected to the
DCRU® unit in your powered DL-110 B-Unit, you must cycle the
power on and off slowly to maintain proper synchronization between
each powered unit’s reverse unit. If the units should become
unsynchronized, simply shut down power for three or more seconds.
Upon repowering, each unit should come up in RESET. If you choose
to operate your existing DL-109 A units in a “locked-out” state, a
lockout switch on the powered DL-110 B-Unit has been provided so
that you can manually “lock-out” the B-Unit in the same direction the
powered A Units are configured.
