echanics, unless you’re careful, lifting a load with your M88A1/A2’s boom
can cause a lot of damage to your vehicle’s wire rope assembly and hydraulics.
Pay particular attention to these two problems areas:
1.
Be careful when paying out
or retrieving the boom winch’s
wire rope. If the rope’s not
straight up and down, it will
bind as it rides in the pulley
sheave. That’s a knot you’ll have
a hard time untangling.
So, when you set up for op-
eration, keep the boom and the
object to be moved or recov-
ered in a straight line. That
keeps the rope straight and pre-
vents binding.
2.
Make sure the stay line support arms are flush
against their stops before lifting. If they’re not,
the hydraulics support the entire weight of the
load.
If the load’s heavy enough, the hydraulic cylin-
der seals will blow. Even light loads will weaken
the seals and shorten their life.

Before traveling over muddy terrain, remove the two screws that hold each of
the fenders in place. The fenders can then swing freely on their hinges, lessening
the impact of the mud.
Reinstall the screws when you reach your destination or when mud is no
longer a problem. The fenders protect soldiers and other vehicles from rocks
thrown by the tracks.

.
As your vehicle plows along, the tracks throw gobs of mud against the fenders.
Enough of that will damage or break the hinges that fasten the fenders to the
hull. Then your unit pays to replace
the fenders.
