Also keep water away from the IR
ejector. If water gets down the IR trans-
port hose into the grinder, it can lead
to corrosion that causes the grinder to
seize.
Keep your feet off the fog oil pump
motor, too. That breaks the seal around
the electrical connector, which lets wa-
ter into the pump motor and leads to
seizing.
Keep It Dry
Water can short out the engine’s elec-
trical components and lead to corro-
sion. So keep the engine compartment
turbine enclosure covered with the
M56’s tarp when the generator’s sit-
ting for long. If water’s getting into
the enclosure, it’s probably because the
lid isn’t sealing properly. Your support
can adjust the lid hinges to stop leaks.
Be careful not to spray water into the
enclosure’s intake vents when you wash
the M56.
Check the bottom of the engine
enclosure for water after a rain or
washing. If water gets in the engine
compartment, drain it by removing the
drain plug at the bottom rear of the
enclosure.
If you let the M56 run dry, air gets
in the fuel lines. To get it out and start
smoking again, you must bleed any air
from the fuel lines and the fuel filter/
water separator after you refill the tank.
See Para 3-13 in TM 3-1040-282-10
for the procedure.
Even then, you still may have trouble
re-starting.
So always fill the tank at the begin-
ning of operations—but don’t overfill
it. Heat expands fuel and that can lead
to leaks. Fill the tank only until the
fuel is just above the strainer.
A full tank will last about 2 hours.
Finally, don’t toss stuff like helmets
into the cab of the truck. It doesn’t
take much of a hit to break the toggle
switches on the control panel. If it’s a
problem in your unit, find a cardboard
box that fits over the control panel and
keep the box on the panel when you’re
not operating. That will protect the
switches.

s you and your new M56 smoke
generator get acquainted, there are a
few things you can do to smooth your
smoking.
Keep It Fueled
Pay attention to the fuel. There is no
fuel gauge, so you must keep an eye
on the fuel warning light on the con-
trol panel. Once it lights up, you have
only 5–10 minutes worth of fuel left.
Stop smoking immediately if at all pos-
sible and fill the fuel tank.
