bayonet assembly by engaging bayonet tabs in housing, pushing in
then turning clockwise 1/8 turn to a full stop (Fig. 12).

the service indicator is red, the mechanism has been fired or is
incorrectly fitted and the inflator requires service. See
Re-arming Your PFD (MD3083 and MD3084) (p. 10).
NOTE: The service indicator must be green before proceeding.
