Protect It
If you’re not looking through the ITAS,
lock the TU in the azimuth and elevation
positions and put it on standby. Otherwise,
hard jolts during movement can damage
the sight and that’s an expensive Fx.
If the sight isn’t mounted, it should
be stored in its case or strapped down
in your HMWWV. If you leave it lying
unprotected on the ground or loose in the
HMWWV, count on it being damaged.
Never throw equipment into a HMWWV
that’s got an ITAS. One good shot to the
sight can ruin it.
Cable Cautions
There’s no need for you to take off the cable that runs
between the traversing unit and the target acquisition
system. So leave the cable alone! If you repeatedly take
it off and put it back on, you risk damaging cable pins.
That can be an expensive repair.
Never tug on the cables. That causes them to fray
at the connectors and eventually the cables have to be
replaced.
When you have the HMMWV interface cable con-
nected to the ±CS, watch your feet. It’s very easy to step
on the cable where it lies on the truck’s floor, which can
put the cable out of action. Use the cable mount to wind
up excess cable to keep it out of the way.
Handgrip Help
Never pick up the TU by the
handgrips or anything else on the TU
that’s black. ±irst stow the handgrips
and then reach under the handgrips to
pick up the TU by its body.
m
echanics, there is one thing you should never do to your MK19 machine gun—
lubricate it with cleaner lubricant protectant (CLP).
Using CLP on the MK19 affects the gun’s Fring, destroys its alloy coating and
causes the weapon to corrode. Then it becomes unserviceable.
Always use a light coat of LSAT lube inside the feed tray before and after Fring,
like it says in TM 9-1010-230-23&P. You can order it in a can, NSN 9150-00-949-
0323, or tube, NSN 9150–01-109-7793.
LSAT is the right lube—CLP is the wrong lube. You can also use the GMD lube
listed in WP 0010 00-4 of TM 9-1010-230-10. Order 14 ounces with NSN 9150-00-
935-4018, 6

pounds with
NSN 9150-00-223-4004, or 35 pounds with NSN 9150-

Leave TU/TAS cable alone
When
you’re not
operating, keep
the handgrips
stowed. That
protects them
from bumps

that can break
