Moving with an open ramp can also
break the ramp cable and damage the
pump. So make sure the ramp is fully up
and locked before you move out.
✵
Don't move the carrier while the ramp
is down or not fully locked. That warps
the ramp so it won't seal, breaks the
locks and damages the hinges.
✵
Lock the ramp door, too. An unlocked
door will fly open suddenly when the
ramp is lowered. That breaks the door's
hinges and can ruin the ramp's hydraulics.
✵
Eyeball the ramp's nonslip coating. A
worn surface makes for tricky footing,
especially in wet weather.
✵
Don't race the engine to raise the ramp
faster. It takes 15-20 seconds to raise the
ramp at 1,200 rpm. It'll go up quicker at
higher rpm—if the ramp pump survives,
that is. Go slow and save the pump.
✵
Never drop the ramp too hard or on
uneven ground. That puts a strain on the
hinges, pump and cable. Once again,
slow and steady is the way to go.
Recoat a worn ramp like this:
1.
Wash the surface thoroughly with soap and hot water. Use a
nylon scrub brush to remove dirt, grease and loose paint. Rinse
with hot water to further cut grease and oil.
2.
Let the ramp dry completely.
3.
Use a paint brush—such as NSN 8020-00-245-4516—to
apply nonslip walkway compound to all the bare patches. NSN
8010-00-141-7838 gets a gallon of the olive drab compound.
4.
Allow the compound to dry for 24 hours before stepping on it.

C
rewmen, if you want the ramp on your
M113-series carrier to work on the bat-
tlefield, take good care of it now.
✵
Never store equipment on the ramp.
It's not a storage rack for tent poles, con-
certina wire and camouflage nets. The
ramp is heavy enough as it is. Extra
weight will just break the ramp cable or
damage the hydraulic pump.
