Mustang Survival MD3003 - Re-arming Your PFD After Manual Inflation (MD3003); Special Considerations for Automatic Devices (MD3031)

2) Oral inflation
Properly armed and inspected, manual Inflatable PFD models will
inflate. However, should inflation not occur, or in a non-emergency
situation, you can fully inflate the PFD by mouth (Fig. 12). To orally
inflate the PFD, first locate the oral inflation tube by opening the
wearer ’s left front panel of the PFD. Then remove the dust cap from
the end of the oral tube and blow into the tube until the PFD is fully
inflated.
3) Automatic backup inflation (MD3031)
Inflation will occur automatically within seconds after the inflator
is immersed in water. The water-sensing bobbin will disintegrate,
triggering a spring-loaded plunger, which punctures the CO
2
cylinder
to inflate the cell (Fig. 4).

Information for both models: The carbon dioxide used to
inflate PFDs will slowly permeate through the fabric cell over
time. A slight reduction of pressure will be observed after
several hours of inflation. Topping up by oral inflation may be
required in the event of very prolonged immersion.

1) Unscrew and inspect the CO

cylinder. If used or damaged, discard
the CO
2
cylinder (Fig. 4).
2) Check the manual lever to ensure it is in the up and ready position
with the green indicator pin properly installed. If the green indicator
pin is missing or damaged, replace it (Fig. 2).
3) Install an unused CO
2
cylinder by screwing it into the top of the
inflator and hand-tighten. Do not over-tighten, as this can damage
the internal gasket.
4) Refold the PFD in accordance with the Repacking instructions (p. 11).
Your PFD is now ready for use.
Special Consideration for Automatic Devices (MD3031)
Premature automatic inflation causes several risks that you must address
to avoid drowning. The PFD might not be armed when needed, either
knowingly or unknowningly. Much less common but also important are:
1) Double inflation (CO
2
cylinder inflation after full oral inflation) could
damage the PFD,
2) Inflation when stored in a tight space could damage the PFD, and
3) The PFD could inflate when you are in an awkward place or position.
Inadvertant inflation may occur in certain conditions, including when the
