Exercise–
The worst thing you can inflict on your MLRS is to
just let it sit. If it sits without exercise, the batteries run down,
the rollers on the booms freeze, and the hydraulic fluid turns
to gunk, among other things. Exercising the launcher during
weekly PMCS can help avoid many problems.
W19 and W20 cables—
These cables
often are broken during reloads because
Soldiers get in a hurry and yank on
them. That extinguishes Fring. The way
to disconnect them is to completely
unlock the cables’ connectors and then
pull straight back on the connector. Do
not pull on the cable–that breaks wiring.
After travel, clean the W19 and
W20 connectors with compressed air
and a soft brush. If the connectors are
plugged, you get non-existent faults
for major problems, which can waste
troubleshooting time.
Travel lock–
Remember
that to unlock the travel
lock you must Frst turn off
all the power or the MLRS
will try to lock itself back
in place. If that happens,
the ratchet extension will
be jerked from your hand,
which could injure you.
Hydraulic fluid—
Too many MLRS
units check the hydraulic fluid rarely.
..
or never. If the fluid gets too low, the
launcher will move erratically or not
at all. During your weekly PMCS, just
give the sight glass a glance. It should
read GOOD. If it’s not, tell your
repairman so he can add fluid.
Any time the launcher is moving
strangely, check the hydraulic fluid
before anything else. That could save
troubleshooting time.
Hoist cables–
Keep an eye on
the metal cables
for the hoist. Look
for fraying, tears,
bends or any signs
the cable is failing.
If it breaks during
operation, you could
have to replace the
hoist drum. Plus
when the cable snaps
it could whip out and
injure someone.
