Smart Cards Available
AFES smart cards are available that cover several different vehicle systems.
The smart cards address AFES safety, provide an overview of the system and
±re suppression controls, cover PMCS and explain how to manually discharge
the system.
Three cards are available. The ±rst covers the M1114, M1151, M1152, M1165,
and ECV2 HMMWVs as well as the Husky IVMMD (interim vehicle mounted mine
detector). The second deals with the M2/M3-series Bradley, Stryker, Buffalo A2 mine
clearing vehicle, Light Armored Vehicle (LAV), and Armored Amphibious Vehicle
(AAV). The third covers the MaxxPro and Cougar JERRV (joint EOD rapid response
vehicle) MRAPs, the Buffalo mine clearing vehicle, and the RG-31 series mine
protected armored personnel carrier.
What to Do During a Discharge
If you have a discharge, stay calm. If the discharge was accidental, simply exit the
vehicle. Then report the discharge so your maintainers can re±ll the extinguisher and
try to determine the cause of the discharge.
If it’s a ±re-related discharge and you’re in a combat situation, stay in the vehicle
until the tactical threat clears. The discharge can be uncomfortable, but you’ll be ±ne.
C
rewmen, the idler wheel on your Bradley won’t do you much good if it’s rolling
away down the trail. But that’s what can happen if you don’t keep an eye on the idler
wheel nuts.
Hard driving in the ±eld can loosen the nuts. Once one nut loosens, it puts more
pressure on the other nuts. Pretty soon, the wheel’s wobbling and can break loose.
Check the idler wheel nuts after every operation. Look for a shiny area under the
nut where it has rubbed against the wheel. Tell your mechanic if you spot any. He’ll
replace loose nuts with NSN 5310-00-175-2710 and torque them to 151-161 lb-ft.
If you spot loose nuts while you’re in the ±eld, go ahead and tighten them. Just
make sure you mark which nuts were loose so your mechanic can replace them when
you get back to the motor pool.
