Keep track of how long the ITAS needs to cool down to operating temperature.
No matter how hot it is, the ITAS should cool to operating temperature within 15
minutes. If your ITAS is taking longer, it needs to be checked out by maintenance.
Something is wrong.
T
he basic TOW missile equipment that was felded in the 1980s with the Bradley has been
replaced by the TOW 2 system.
As a result, all basic TOW test equipment is obsolete and should be turned in. See Figs 1,
47, and 63 in TM 9-4935-474-24P-1 ±or pictures o± the equipment.
These are the items TOW repairmen should look ±or:
Dear Half-Mast,
If we have to shut down the gunner’s display unit (GDU) because the
MLRS launcher is not running, it takes us at least 10 minutes to power the
GDU back up. Is it a good idea to use a small generator to keep the GDU
powered up?
SSG A.H.
Dear Staff Sergeant A.H.,
You shouldn’t need a generator for the GDU. If your launcher batteries are
in good shape, it shouldn’t take 10 minutes to power up the GDU. If it’s taking
that long, get your repairman to check out the batteries. You probably need some
replaced.
Normally, you shouldn’t run the GDU longer than 30 minutes with the launcher
off. The GDU should give you an alarm when the 30 minutes is up. If the alarm is
going off sooner, that’s also a sign the batteries should be checked.

Don’t use the right-hand grip as a handle during travel.
One good bump on
the road and you break the handle. If you need to hold onto something, hold onto
the grip’s protection bar.
Take it slow and easy hooking up the TAS (target acquisition system) to the
TU (traversing unit).
If you follow the procedures in WP 0006 in the TM, paying
close attention to the cautions and notes, you can’t go wrong. Never use force to
mate the connectors. If you’ve done your PMCS and it’s still difFcult to hook up the
TAS, something is wrong. Your maintenance folks need to check it out.
Here are the most common TAS mounting problems:
•
The TU connector is not in the down position before putting the TAS on the TU.
•
The connectors have broken pins
or are plugged with debris or dirt.
•
The locking knob is missing any
of its three connector guide pins,
which ensure the cable connector
goes on straight.
•
The TAS coupling clamp tab is
binding on the locking knob. The
tab is often bent, which prevents a
good connection.
You can usually blow out any debris or dirt yourself. All other problems must be
Fxed by your maintenance.
