The PMCS in TM 3-1040-282-10 doesn’t pay much attention to the Y-strainer
screens. But if they become too dirty, fog oil can’t flow to the generator and you
don’t smoke. So it’s a good idea in the Feld to monthly give the screens a good
cleaning.
With the fog oil shut off, use your adjustable wrench to remove the strainer caps.
Take out the screens and clean them with dry cleaning solvent and reinstall them.
Save yourself clean-up by laying a rag under the Y-strainer before taking off the
strainer caps. The rag catches any fog oil dripping out.

If you have trouble with the
cap
for
the
dispersion
cone
disappearing, poke a small hole
in the cap, run a piece of 550 cord
through the hole, and knot the end
of the cord. Tie the other end to
the cone’s heat shield. Then you
can just let the cap dangle when
you’re operating. Remember you
must let the dispersion cone cool
down before you put the cap back
on or the cap melts.

The half door on the
right side of the M56
doesn’t
latch
well.
Some units try to Fx the
problem by tying off
the door to the transport
hose. Bad idea. That
damages the hose. The
solution
is
to
use
a
bungee cord to secure
the door to the platform
above the grinder.
•
Don’t use the IR hopper for storage. If you accidentally hit the graphite switch
when stuff like packs are in the hopper, the hopper is damaged, as well as the
intromitter drive assembly and auger shaft.
•
If nothing happens when you try to
start the M56, check the GEN PWR
switch. It should be ON. If the switch
is ON, make sure the three circuit
breakers are pushed in. No change?
Do the troubleshooting in Table 3-1
in TM 3-1040-282-10.

Stand forward of the front of the rear tire when the turbine is operating. This puts
you out of danger if the turbine Fns ever break and come flying out or debris shoots
out the turbine exhaust.
•
Remember to reset the ejector gap setting when the temperature changes a lot.
Otherwise, you’ll have smoking problems. The procedure and temperature settings
are on Page 2-44 in the -10.
•
Wear your helmet when driving the M56. If you don’t, you may dent your
head on the bracket for the driver’s vision enhancer during a sudden stop.

if you have trouble smoking
in cold weather, check these
strainers. Condensation can
freeze in the strainers and
block fog oil.
if that’s the case, melt the
ice with the truck heater.
