Keep in mind that ammo's not at its best when it's been exposed to extremely
high or low temps. So, put aside ammo that's been roasting or freezing. Also,
some components won't do much for you in a heavy rain storm. When specific
temp ranges or other firing restrictions apply, of course, they'll be quoted on
the ammo, its box or container, and for sure they'll be given in the weapon's TM
or the ammo pubs or firing tables.

Same goes for rockets with

S The grains of black powder in a propellant igniter
bag must move easily to your touch. If they're stuck

damp propellant, or improper ignition of propellant will

Never load HE and chemical ammo
in the same vehicle, and use whatever
cushioning you can around the fuze
boxes. Never cart POL, or any other
type cargo with your load.
Spread the load evenly over the cargo
space, but keep the height of the load
well below the top sides of the cargo
compartment, and give the load air
space on all sides. You may need ridge
poles under the tarp to prevent rain
puddles.

I 7n R

Plan your loading so you don't have
to wrestle the ammo too much. In fact,
the less you man-handle your ammo, the
better. Like when you're loading a vehi-
cle, get it as close as you can to the
ammo, and use a human-chain to pass
the ammo gently. To load or unload
boxed ammo you can use smooth, clean
boards to form a slanting ramp and
slide the boxes easy-like on or off the
vehicle.

Any vehicle going close to your ammo load, or totin' it,'must be in top
operating condition, especially the electrical, fuel and steering systems and
the brakes. It must be real clean. No oil, fuel, grease or any other flam-
mable stuff sticking on anything. And, it must be equipped with a flame
and spark arrestor, and good fire extinguishers must
be on board.
And, whether it's loaded or unloaded a vehicle

Belted machine gun ammo and other small arms ammo collects lots of mois-
ture when it's stored in a combat vehicle. So, you have to keep a close check on
it, wipe it dry and air it out, or it'll be ruined in no time. You can beat the
moisture problem some, if you open the doors, ramp, hatches, etc., when you can,
to let outside air hit the ammo.
Large rounds stored in the vehicle's ammo racks also need regular attention.
They're normally inspected or unloaded for cleaning as called for by the com-
mander's SOP. And, when you clean, paint, grease, oil or wash anything inside
the vehicle, you have to protect the racked and packed ammo from whatever
you're using. Also, when you hose-down the outside of the vehicle, close it up
to keep the inside dry as possible.
r M ^If you're transporting your load in
a chopper, you have to take the ammo
to the chopper .. the bird doesn't come
to where your ammo's stashed. All
switches on the chopper must be off,
the rotor must be secured and the chop-
RIGHT per must have a good electrical ground.
IN While the loading or unloading is go-
THERE. ing on, the chopper should have explo-
S ,-/ sives warning signs attached to its sides.

The ammo boxes and containers must be in good condition (no damage,
breaks, leaks, etc.), they must be tightly sealed and show the ammo's identifica-
tion on the outside. The load must be lashed down like the aircraft commander
says.
The specifics on transporting ammo by aircraft (weights, safety requirements,
compatability of ammo types, etc.) are covered in TM 38-250 (May 68) Pack-
aging and Handling of Dangerous Materials for Transportation in Military
Aircraft.

anything else that may attract light-

airfields, gas dumps, water supplies and ---

Keep all boxes and containers in a
stack headed in the same direction and
with the identification info facing out.
Try for hard, well drained or high
ground, otherwise a good rain may
sink or drown your stacks. You'll
need at least 6 inches of strong, well-
supported dunnage under each stack.
You can use boards, logs, limbs,
stones or small arms ammo boxes filled
with sand or dirt for dunnage. If you
don't have a good storage location
you'll need drainage ditches around
the stacks so water'll not collect under
them.

you go gathering material, be sure the
stripping of trees, foliage, etc., won't
hurt your camouflage or the neighbor-
hood.
In desert-like areas you can use sand,
stones, or dirt to build roofing.
You can use sand bags, canvas,
boards, heavy cardboard, branches, etc.,
for walls.
And the covering, whatever kind it
is, must be at least 18 inches above the
stack and at least 6 inches from all sides
to give the ammo good air space all

_rY~LI C

Never lay canvas or any other covering on top of boxes or containers, 'cause
you'll just be creating a sweaty situation for the stack. And, never nail the
covering right to the stack (nailing and hammering on ammo containers is
dangerous, remember). Secure it with rope, twine or wire, or anchor the cover-
ing some other way so it'll stand up to rain, snow and wind.
In tropical climates you have to check dunnage, tarps and other covering
frequently for mildew, rot, termites, fungus, snakes, rats and the like.

Continuous exposure to moisture and high temps will hurt all ammo even-
tually. But, pyrotechnics and primers absorb moisture like crazy, and once they
do they're done for. So you really have to try hard to keep that stuff dry. You
also have to keep it off to itself and pointing away from other stacks and your
neighbors and friends.
WP and PWP ammo also needs a clear area. You store it on its base, espe-
cially where temps go up to 111 F. The 3.5 WP rocket, though, is an exception
to the WP storing rule .. you have to keep it nose down, never on its tail or its
side, especially where it's hot.
Never store any type of rockets between stacks of other ammo. They go to the
farthest end of your storage area. Store them nose down or pointing away from
other ammo. If you can swing it, face them into an embankment or some similar
barrier.
Stash chemical ammo off to itself,too,and place it so each round can be easily
inspected and quickly removed from the stack. Locate it so it's downwind from
your tepee. GT
AMMOa OWN

Keep fuzes for separate-loading ammo off to themselves as much as you can,
in case a fuze goes off by itself. Remember, fuzes are real sensitive to high temps,
direct sun heat and high humidity.
Stack rounds with perforated cartridge cases away from all pointed objects
(nails, wire, tools, sharp rocks, twigs, etc.). Never let them lie on the bare ground,
not even at the gun site.

Mines are waterproofed for ground-laying, but like all other ammo, they have
to be kept boxed and protected from moisture and shock until they're needed.
Keep the ammo area clear of trash, dry grass, rags, broken glass, glass con-
tainers and anything else that might help start a fire. Make sure fire extinguishers
and a water supply of some kind is handy to your stored load.
Your load, of course, has to be guarded or secure around the clock. See AR
190-11 (Aug 68), Weapons and Ammunition Safety.

The word on duds is -let 'em be. Touching, moving
or bothering a dud the least bit may activate its fuze.
Report duds to the Ordnance ammo types. If there's a
malfunction, hold all material for the ammo officer.
Never toss away defective ammo, or leave behind
ammo that's not fired. Report it so whoever's responsible
will get it turned-in or taken care of. If you abandon
defective or unused ammo, someone you like may acci-
dentally stumble on it. Also, you might be throwing
away important info on a defective lot that should be
investigated so you won't get more of the same. Or the
enemy might find it and rig you up a booby trap.

-"trhe am officer, NCOIC, the supply types, or some other wheel your
outfit keep the record straight on the outfit's authorized basic load.
The needed nose-count or paper-work is set up by the CO's SOP. They use
DA Form 581, Request for Issue and Turn-in of Ammunition, like it says in
para 4-3, Ch I (May 68), AR 735-35. They follow AR 700-1300-8 and Chap 5,
TM 38-750 (May 67), plus the local ammo safety and reporting SOP, to take
care of defective ammo, malfunctions and accidents.
But, it's up to you to let them know (as soon as you can) whenever you have a
problem-and, that includes a hangfire, misfire or cook-off.

DIRTY PICTURE WITH A MORAL:

NEVAH SHOULD HOPPIN!

BUT I LUBEP
i 4..\ IT LIKE NORMALLY.

/- (CORRODED TUBE?

Water in the stock well plus lack-o-lube
sets up galvanic corrosion on the alum-
inum tube and phooey, another
M16A1 rifle out of action!
So who goofed -Speedy or Zapper?
Or both?
The good book says you armorers have to clean the outside of the lower
receiver extension-at least once a month,but lots oftener if conditions call for
it, like in the action area.
However, you riflemen have to make sure your armorer gets a chance to do
the job. Might be he'll let you help him, but don't tackle it by your lonesome,
otherwise.
Anyhow, the moral's clear: Never neglect this part of your zap machine!
Zapper-First chance you get after coming back from a firing mission split
over to Speedy's hootch and get him on the ball.
Speedy-Take the stock off the M16 and then do your PM thing, according
to what you find. If the tube's not corroded at all:

2. Sook a clean rag with ISA and put a
generous coat on the entire outside
surface. j~ V

1. Wipe it good and dean with a dry rag.

O'c6urse, this is just part of the deal
you have to pull on the lower receiver
extension w while doing Item 6 of the PM
Checks and Services bit in Table 3-2 of
'your -12 TM.
Natch. like the book sa s, you'll also
clean and lube the decents and springs
Sfor he takedov n pin, piort pin and se-
Slector lever at the same time. And \ou'll
get a dose of LSA in the decent well. too,
like Table 3-1 sa.s. A pipe cleaner
dunked in LSA -orks fine here.
S .A All clear?

STICK TO THE BURRS
I JUST FILED
OFF THE BURRS. TO
MUCH!
YOU
COULD
GET
SLOPPY
WHY DO YOU TRIGGER
ASK?F ACTION!

Easy does it, hey, you armorers, when
you're filing down burrs on the shoulder
of the M14 rifle's trigger housing.
File the burred areas only, especially
where the raised shoulder meets the
groove in the receiver. Never mind the \
rest of the housing. And stop filing
when the burrs are gone.
Elsewise you'll change the shape of
the parts and have sloppy trigger action.
Incidentally, use a real fine file or FILE THE BURRS ONLY
stone for the job.

YOUR M16 PARTS FROZEN?
USE BORE CLEANER ONLY

I

Here's how to use it on frozen parts.

Listen. If pans, derents and springs
on )our MI1A I rifle get frozen tight,
don't bother shopping for some exotic,
big-name, off-the-shelf stuff to loosen
em up. In fact, .ou'd better not!

Watch it! One li'l slip- like touching a battery cable i

Your alternator can't take current

verse polarity) is enough to put your
alternator out of action-to the tune
of more'n 6200!
That's wh) )ou'%e got to be extra
careful around this AC-DC charging
system-like it tells you in para 06-16,
TM 9-2320-244-20 (Oct 68) and on
page 2-50, TM 9-2320-218-20 (Aug
68).

Always make sure you've got posi-
tive-to-positive and negative-to-nega-
tive when you're making' hookups to
your battery and alternator. No day-
dreaming, or you'll goof like Flubup
Fumble did:
He installed the positive cable on the
negative (-) battery post. Then, natch,
he made the second, and fatal, mistake
-he put the ground cable on the posi-
tive (+) battery post. BLOOEY! One AN ACCIDENT? YEAH, BUT YOUR ALTERNATOR
perfectly good alternator blasted. DOESN'T UNDERSTAND MISTAKES.

,- ACCIDENT INSURANCE
SYou can cut down on the chances of
.W' making this mistake bs placing your
batteries so it's almost impossible to put
a cable on the wrong post. With both
negative (-) posts on one side and both
positive (+) posts on the other side, F
)ou won't have to worry about drop- SAFER
ping the cable on the w wrong post.
On your "' 15 and M725, you can use the same cables you've got.
On your M151A1, though, you'll need a longer cable for hooking your bat-
teries together. Your TM 9-2320-218-20P (Apr 68) lists FSN's for wire, terminal
lus. insulation sleevine and marker band to make a new Inneer ciabl

There's not much chance you'll be issued a battery that's been charged in
reverse-but it has happened. Once is too much-that ol' reverse polarity
again-BLAM-scratch one alternator.
So always check a freshly-charged battery before putting it in your vehicle.
Make sure it's got the right polarity. It's easy and only takes a couple seconds.

Use the multimeter in your No. 1
Common Tool Kit. Set 'er up like in
Figure 2-10, TM 9-2320-218-20 (Aug
68)-negative lead (black) to the
"COMMON" jack on the multimeter
and positive lead (red) to the multi-
meter's positive (+) jack.
Set the range selector on 50 volts.
Now touch the black lead to the nega-
tive (-) post on the battery and the red
lead to the positive (+) battery post.

If your meter needle tries to go down-
scale (to the left), your battery's polarity
is reversed.

But let's dbublecheck. Switch your
black lead to the battery's positive post
and your red lead to the negative post.
Now if the meter needle goes up-scale
(to the right), you can be sure your bat-
tery's polarity is reversed.
In either hookup, if the meter needle
doesn't move at all, your battery's dead.
If your battery's dead or has reverse
polarity, turn it in for another-and
check that one for reverse polarity, too.

Until you make this mistake, you may not realize how easy it is to ground
your alternator output terminal-short circuit-ZAP-curtains for your alter-
nator.
So be mighty careful when you're
ookoin' up to this output terminal. cThe
cable terminal lug is fattterminaler on one side.
This side goes UP. If you goof and in-
willstall the fa side down, the lug willoutput
touch the plate underneath and short
out your alternator.

And never- but NEVER- use your
alternator for a step or footrest while

There's a handy dandy way to get
rid of a dirr problem when you fill your

in your gun instead of the dunking
method. The GAA grease comes in a

M715.
Requests for the alternator should cite your vehicle
model and serial numbers, TOE number and equipment
requiring the alternator (Angry-46, in this case).

Route the power cable like so:

Remove the knock-out from the front wall Use grommet, FSN 5325-637-8054, around
of the truck bed (about a foot above the bed, the edges of the knock-out hole. It protects
behind the operator's side of the cab). the cable from the sharp edges.

The second grommet, FSN 5325-8264020, dulls the edges of the knock-out hole on the bottom of
the battery compartment, through which you feed the other end of the power cable.

Depending on the production date of your
M715, the second knock-out is on the cab
behind the driver's seat... or in the cab floor.
No matter. When you open it, use insulator
FSN 5970-083-0377 where the cable goes
through the cab.

Adjust the sling to the eyes of the
shelter and truck, as appropriate.
The installation hardware and cables
cited are in SB 11-131 and publications
on the Angry-46 and 5/4 truck.

Of course, you use the 6TN 100-amp hour
batteries, FSN 6140-057-2554, with the 100-
amp alternator kit. The batteries are in TM 9-
2320-244-20P (Oct 68).
Be careful when you're dangling the hot
battery lead around. Even a quick, accidental
touch to the negative post, the truck body or
frame can blow out the alternator if one end
of the hot lead is connected.

The idea is to pull out both sides evenly and together.
If you pull one side out, then the other, you can bend or break the contact

Incidentally, be sure those BA-30 batteries are installed right. That means the

UNTWIST THAT WRIST

Bored? There are 7,967 better ways of curing the problem than twisting the
receiver elements on the handset of your TA-43/PT and TA-312/PT telephone
sets.
Why better? Because if you choose the handset, chances are great that you're
gonna crimp or break the wires on the element.
Now, with those 7,967 other ways, that wouldn't happen.
It's also a good idea to make sure the wires are clear when you put back the re-
ceiver cap.
And, uh, snatching is great in some cases, but not when you're removing the
handset from its cradle. You bust up the retaining springs. Push toward the
springs before you lift the handset up. Same goes when you put it back.

Dear Windy,
Our Loach has a lot of slippage marks painted on it.
When we put in new hardware should we continue to decorate it with slippage
marks?
What's the low down on using slippage marks on all aircraft?
SP6 R. W. B.
Dear Specialist R. W. B.,
The slippage marks on your Loach were put there by the manufacturer as part
of his quality control. Slippage marks for the field are called out in the main-
tenance pub for your OH-6A.
The Aviation Systems Command has no plans to apply the marks generally,
to your bird. Of course a local commander can use the device as an inspection
aid.
But splashing war paint all over your Cayuse, or any bird for that matter, may
not be the answer. Slippage marks can drive you to distraction.
Maintenance and inspection types want hardware to stay put. To assure this,
torque values have been set and lock wire, cotter pins plus other locking devices
added as a safety factor.
Nuts and bolts will do the job they're supposed to do when they're tightened
right, with a torque wrench, and secured with the right safety device.A)j

look at the innards every couple of weeks even if you're
not having overheat just make sure nothing is sneaking
up on you. A petcock test for mud while the radiator is hot
is good insurance.

D isn't the best grade to get in school ... but there're places where D's are hot
on the scene. Like on that new 440HA grader- because D stands for 2 things:
Diesel, and Different. Get with those D's and you'll switch onto the action.
First thing, this Wabco is Diesel, which means forget most of the gasoline-
engine book.
For instance, where your TM says "at operating temperature" in the start-up,
it means 160 or better (except in Far North) on that coolant temp gage.
Even in tropics, shortcutting is unsmart ... 115 in the shade may be hot to
you, but it's chilly to your engine..
SLA COLD DIESEL CARBONS UP WARM
A LOT FASTER. 'ER UP.

Carbon and varnish hide out on guides and stems and rings of cold engines like
snipers in spider holes. Good warmup shoots down that kind of trouble, and it
gets the lube oil to the vitals besides. So make sure you're up to the 160 operating
temperature before you move out.
Those gages read 15' to 20 low in sub-zero climate. So there's a D for Differ-
ence-go through the TM-12 cold-weather drill (para 2-15), make sure your
weather closure is good ... and when your gage has been on 140' to 145 a couple
of minutes, you're safe.

WATCH THAT ENTHUSIASM

These Wabcos can be kinda fun to run-but don't let excess joy get the
best of you. Even taking off from parking can be dangerous-
Like, when you raise your blade, watch your blade lift arms. Keep the
left lift arms to the outboard side of top

When using your 440HA for bank
sloping operations, it's OK to move the
left arms past top center; in fact, it's
necessary during this operation. If you
operate with the left lift arms inboard
S1of top center during normal grading
operations, you can very easily ram the

Otherwise, you can bend the shaft ...

AYE, EYES ARE HANDY
That neck-saving gaze can help you
on a pair of other places, too. One of
them is another new-machine checkover
bit, only for this'n you wait 'till your
440 has been run 3 days or so-not
less'n 1 or over 4, that is. Then have
your support unit mechanic retorque
your tandem wheel hub nuts. The right
out-of-gear figure is 600 lb-ft. Be sure
your front wheel bearings ride snug,
too.
The other look-at-often is your cool-
ing system. Look and clean when needed
with an air hose. If you can make it
without splashing hot pipes and elec-
trical equipment use a water hose every
now and then. Keep mud, oily sand,
76

leaves and trash, and of course all old
worn-out $10 bills out of the radiator
fins and honeycomb air passages. Every
time you do that, clean the breather cap
on your lower transmission housing.

BLOW OUT THE JUNK,USE LOW PRESSURE AIR AND WEAR GOGGLES

NO SOUP ON THE MENU
Never think your 440 can do better souped up.
Your favorite Uncle had it souped down. A bigger injector or a jazzed-up
governor will only add heat, and heat means trouble.
There's a chance-but slim-that you might get a Wabco-type with an
old-style hydraulic pump. If you do, you're in trouble.
So requisition from page 7 of that fold-in section of your factory manual
labeled "Draft List of Stock Type Items."

You can stop parking brake failures on that LARC-V. Just put your trust in
the word, "adjust," and do the adjusting like TM 55-1930-205-20 (Apr 66)
says on page 48, figs 3-48 and 3-49, using the lever knob to take out slack. One
big help is-don't move out with the parking brake engaged.You might have

WELDING BOOTH PAINT
USE THE Dear Editor,
RIGHT PAINT, Healthwise, not just any paint will do for a welding
area or booth.
The right kind of paint is needed to reduce the hazard
of eye burn for individuals in the area. It doesn't have to
be a costly, special covering, but the paint should be lus-
treless or flat, so the welding are won't be reflected, and
it should reflect a minimum of ultraviolet radiation from
the arc.
The following paints meet the safety requirements.
They're available in the supply system from GSA in 1-gal

Yep -''tis true you keep anti-
freeze in your carrier engine on the
Model 2380 rough terrain crane--and
in the crane engine too ... winter and
summer, tropics and Arctic circle, makes
no difference where you are.
And in your chromate corrosion re-
sistor, you use nothing, but nothing as
a substitute for FSN 2930-929-5501. If
you run out of antifreeze and just have
to use water, no filter at all is better than
what's been around up to now. In any
case, you never let the Perry chromate
filter sack (Item 23, Fig 46, TM 5-2420-
206-35P) touch your antifreeze solu-
tion. Leave the two plates in-they're
good at fighting electrolysis (that's
Irbanian for water rheumatism).

DON'T

SUBSTITUTE.

The same thing goes for your 290M
tractor, too-it wants antifreeze the
year round, and no Perry chromate sack
in the filter. This word is on page 38 of
TB 750-971-1 (Feb 68).
