f the trailers for your Patriot Missile System are in bad shape, you’re in bad shape
because you can’t move your Patriot. Here’s how to keep your Patriot mobile:
Be careful with the inter-vehicular
cables.
If you force the cable connectors
in place, pins get bent, leaving the trailer
with no lights. Line up the connector and
the receptacle and then carefully push in
the connector. If it won’t plug in easily,
something is wrong. Get a repairman to
check it out.
Also make sure the cables are securely
plugged in. If they’re not, the cable can
come unplugged and drag along the ground,
which damages it.
During BEFORE PMCS, check the cables’ connectors for bent pins or a damaged
metal sleeve. Tell your repairman if you spot problems.
Remember to unhook outrigger
safety chains.
Lots of safety chains
are snapped off each year because
Patriot crews forget to unhook them
before they lower the outriggers.
There are four outriggers on each
trailer. Visually check each one’s
safety chain
before
you lower the
outriggers. A snapped chain makes
the trailer NMC.
Dear Editor,
In PS 684 (Nov 09), you talked about the importance of putting the MK
19 machine gun’s safety slide in correctly. If it’s installed backwards, the
MK 19 could fire even when it’s set on SAFETY.
But you said the correct
position of the slide is
with its tab facing to the
rear. That’s confusing. You
should have said the tab
should face the top of the
gun and toward the gun’s
right side.

Editor’s note:
Good point,
Sir
. When you’re standing behind
the weapon, the slide’s tab should be on the right and should
point up. See Item 4 in WP 10700-2 in TM 9-1010-230-23&P.
Dear Editor,
An exploding battery in the Patriot missile system is something you want
to avoid at all costs. This tip can help:
Label ethylene glycol
cannisters.
Ethylene glycol is
used in the radar. Unfortunately,
the canister it comes in looks
like the one for battery acid.
We’ve had repairmen mistakenly
put ethylene glycol in batteries,
which could cause them to
explode. We avoid that mistake
by marking on the bags for
the canisters whether they are
battery acid or ethylene glycol.
