MLRS Launcher…
•
Tighten all LRU cables and cannon plugs before washing.
Loose connectors will let in water that can cause short circuits.
•
Cover the electronics unit (EU) and electronics box with a
plastic bag before washing. Both boxes have a gasket to pro-
tect against water, but you never know when the gasket will
go bad. The bag provides an extra line of defense. Don’t forget
to remove bag after washing it.
•
Park the vehicle so water can drain freely from the hull.
Make sure all drain plugs are unclogged.
•
Never use high pressure water for cleaning. That will force
water past any protection.
Installation
Unless you have long, skinny fingers,
you'll find it difficult to tighten the cable
for the M3P. Once you have the cable
connected, use needle-nosed pliers to
tighten the connector.
Rate of Fire
The wrong rate of fire will cause feed-
ing problems. Check the rate of fire on
the CDT (control display terminal). It
should be 950 to 1,100 rounds per
minute. If it's off, reset it like it says on
Page 4-31 in TM 9-1425-433-10.

PMCS
• The clip for the pin
that locks the M3P to
the mount. Without
the clip, the pin can
come out and then the
gun bounces around
on the mount.
• The two pins that hold the ammo box in place. Make sure
they're both in place and can be installed. The ammo box bracket
is often knocked out of alignment and the pins won't go in their
holes. Then the ammo box can't be locked in place.
Two areas
to check
during pmcS
are…
Clip
installed?
Two pins present?
Do they fit in
bracket?
Check rate of
fire on CDT
a
good washing
is the best way to

keep these things
in mind…
