T
he skid-mounted 60-KW tactical quiet generator (TQG) is suffering under the
weight of some big-foot abuse.
Located right in the middle of the left-side skid is the fuel drain. If you need to
look on top of the generator or over it, that fuel drain seems like the perfect place to
step. But the drain was never meant to take on that kind of weight. You’ll bend or
break the pipe and bust off the T-valve.
Sure, you might get away with it a few
times—maybe you already have—but
eventually something is going to snap.
Then you’ll have a dangerous mess on
your hands and a piece of equipment that
is NMC.
So keep your big foot off the fuel
drain. And put your big paw on the
shoulder of your pals that you see doing
it and give them the word, too.
S
ome of you MSE shelter operators are holding on to the old 2HN lead-acid back-
up batteries, NSN 6140-00-057-2553, like they were gold bars. Replace them
now
with sealed, maintenance-free batteries, NSN 6140-01-446-9554.
The old non-sealed, lead-acid batteries.
..
...are difficult to maintain.
Checking and filling the batteries requires partial dis-
assembly of the shelter power bay. Over-filling the batteries can lead to electrolyte
overflow. That acid runs down into the battery box, corroding the box and vent fan
assembly.
...vent hydrogen.
When the “equalize-charge”
mode is used to quick-charge batteries, they’re
often overcharged. That boils the electrolyte,
releasing large quantities of hydrogen gas.
Maintenance-free, sealed batteries
last
20% longer, operate safely in a wider tem-
perature range (from -22° to +122°F),
and
can be deeply discharged for many cycles.
You can make the switch now, if your old
batteries need replacing. Change both batter-
ies in the shelter at the same time to get the
best results.
Hey…
You’re
gonna
break
my back!
We’re
here for
you!
There are
plenty
of
shelters for
all of us!
Switch to maintenance-
free batteries
Keep your foot
off the drain!
