hecking the ramp hydraulic reservoir level is a daily task, drivers. It seems simple
enough, too. Just make sure the fuid level is halFway in the sight glass, right?
Not so Fast. There are two more steps involved to check the reservoir level the
right way.
STEP 1:
Your vehicle must
be parked on level ground. IF the
vehicle is on an incline, the sight
glass reading may make it appear
that there is too much or too little
hydraulic fuid in the reservoir.
IF you adjust the level based
on a Faulty reading, you could
end up with too much or too
little hydraulic fuid. Too much
means a big messy problem with
±RH leaking out oF the hydraulic
system tank breather. Too little
results in a ramp that moves
erratically or not at all.
STEP 2:
The ramp must be all the way down. IF you read the reservoir sight glass
while the ramp is closed or partially open, the reservoir will appear to have too little
hydraulic fuid.
You’ll ²nd these two steps on Card 17 oF LO 9-2350-277-12 (Jul 94, w/Ch 1,
±eb 97).

irt, sand, oil, and condensation have a habit of collecting on your Paladin’s slip ring, crew-
men. As the turret is traversed, that crud builds up on the segment board and shorts it out.
Things go downhill from there. A shorted segment board shuts down your commo
and the vehicle motion sensor. You’ll also get navigation faults in the automatic fire
control system.
1.
Remove the cover plates over the
segment board.
2.
Soak a nylon scrub pad, NSN 7920-00-
753-5242, with denatured alcohol and
clean the exposed portion of the board.

won’t
your

close?
cause you
didn’t check
it right,
that’s
why!
4.
Manually traverse the turret enough to
expose the next portion of the segment
board and clean again. Keep manually
traversing until the entire board is
clean. Watch out, though! Using
power to traverse the turret will give
anyone cleaning the segment board
a big
shock!
3.
Wipe the scrubbed area of the board
again with a clean cloth
