Reactivation

the projectiles removed from the rack assemblies and stowed items removed

from the stowage boxes at the top of the rack assembly. If the vehicle is

not level, the racks may tip over and cause injury or equipment damage.

When both racks are to be moved, the right rack assembly is the first to be

removed. When only one rack is to be moved, the stacker is positioned in

front of the stationary rack to keep the stationary rack in a more secure

position.

The final step for fire extinguisher deactivation is to ENSURE the locking

pin (Item 5, Figure 11) is installed in the valve actuator guard (Item 6,

Figure 11) before disconnecting the fire extinguisher harnesses. After the

locking pins are installed, loosen the nut (Item 7, Figure 11) which secures

the dispersion nozzle (Item 8, Figure 11) to the cylinder bottles. Ensure

the nut is only loosened and not removed. Immediately after the dispersion

nozzle is removed, remove the anti-recoil plugs (Item 9, Figure 11) from

their holding fixtures and install them on the extinguisher cylinder

bottles. You are now prepared to perform maintenance or repairs on the AFES

as required.

Reactivation.

You have completed the necessary inspection, maintenance, and repair on the

AFES, now you must reactivate the system.

The reactivation process is

basically the deactivation process in the reverse mode.

The first step for you to take in order to reactivate the AFES is to remove

the anti-recoil plugs (Item 9, Figure 11) from the cylinder bottles and

secure them in their holding fixtures.

Immediately after removing and

securing the anti-recoil plugs, install the dispersion nozzles (Item 8,

Figure 11) on each cylinder bottle and tighten. Now you must back off the

nozzle (no more than one turn) until the engraved line (Item 11, Figure 11)

is in the up (vertical) position then tighten the nozzle nut. At this stage

of reactivation, remove the locking pin (Item 5, Figure 11) from the

actuator guard on engine cylinder bottle no. 2 and crew cylinder bottles no.

3 and 4. Do not remove any other locking pins. Reconnect battery ground

cables and set the MASTER switch to the ON position.

Now set the

MAINTenance switch in the horizontal (power on) position and verify that the

Built-in Test Equipment test was successful. Refer to Part E - Performance

of AFES Test, for details on conducting the BITE test.

Upon successful

completion of the BITE test, move the projectile racks to the front of the

vehicle as outlined in TM 9-2350-267-10.
