our M17 or M12 decon won’t
be deconning if you’ve been care-
less with the 65-gpm pump.
Here’s how to keep the pump
pumping:
If the pump is going to be
off for more than 10 minutes, shut
off the shut-off valve. Otherwise,
the carburetor will flood and the
pump will be hard to start.
Don’t confuse the shut-off valve with
the carburetor valve. If you acciden-
tally turn the carburetor valve, you’ll
mess up the carburetor setting. Then
you’ll really have starting problems.
The shut-off valve sits on top of the
fuel filter.
If the carburetor ever gets flooded,
close the shut-off valve and give the
starter five pulls. That should drain the
carburetor enough for it to start. So
turn on the shut-off valve and try to
start the pump again. No luck? Do the
procedure one more time. Still no luck?
Tell your repairman.
Tie the starter rope to the handle on
the opposite side of the starter pulley.
That keeps it from being caught in the
spinning pulley.

-i feel so
chipper
!
1.
Make sure batteries are installed.
2.
With power off, simultaneously
hold down the CLR/TST, DOSE
PER HR, and ACCUM DOSE
buttons.
3.
Turn on the power with the
buttons still held down. All
LEDs should illuminate.
4.
Release the three buttons and press CLR/TST. You should see 01.
5.
Press CLR/TST again. You should see 31.
6.
Press CLR/TST again. You should see 94.
A date other than 01 31 94 indicates the MWO hasn’t been done. Your TMDE
will have to perform the MWO and calibrate the radiac set.
MWO 11-6665-251-40-1 added an electronic chip to the AN/VDR-2 radiac
set that made it easier to set the attenuation factors and store accumulated dose
readings.
