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

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.
