REMOVAL
WARNING
Any automatic fire extinguishing system (AFES) unit in need of maintenance or
repair is more prone to accidental discharge. Accidental discharge could lead to
frostbite or other injury. Small parts or tools become dangerous projectiles when
propelled by Halon discharging at 750 psi. Do not strike cylinder bottles with tools
and do not drop cylinder bottles. To prevent accidental discharge, be careful when
handling cylinder bottles.
The engine AFES is designed to provide from 2 to 4 hours of fire protection AFTER
vehicle shutdown. Turning off the master switch does NOT deactivate the AFES.
Working on the AFES when active may cause serious injury to personnel.
Remove four screws (14), and cover (13) from actuator assembly (3).
Loosen, but do not remove, socket head setscrew (5) securing handle cable(6) to pin (4). Remove cable end
from pin (4).

For correct installation, tag cables when removing.
Remove two nuts (7) and nuts (8) which hold each of two cylinder cables (1) to cable block (1 2).
Remove connector nut (1 O) and three nut (11) attaching lower cylinder cable(17) and handle cable assembly
(9) to cable block (12).
Remove five threaded fittings (2) attaching two handle cables (6 and 9) and two cylinder cables (1) and cylinder
