Lifting Belts
Take care of the mine clearing blade’s lifting
belts and they won’t let you down. That means
using the right lifting techniques.
During operations, always make sure you back
the vehicle 8-10 feet before lifting the blades. That
keeps the blades from hanging up on anything
that’ll snap the belts.
Never use the mine clearing blade to recover
mired vehicles or to lift anything. Either the lifting
belts will break or the motors will burn out.
Never drive the blade through concertina wire.
It’ll nick and cut the belts. When that happens,
your mechanic has to replace them with new
belts, NSN 4020-01-289-8249.
Motors
If the blades come crashing down when the electrical or manual blade release is
used, too little oil or oil contamination could be the culprit.
After
you’ve
conFrmed
the oil level is OK, use the
electrical switch to raise and
lower the blades once more.
If they come crashing down
again, have your mechanic
drain the old oil from each
motor and replace it with four
ounces of damping fluid, NSN
