CAP ON ORAL TUBE IS TO HOLD DIRT OUT – NOT KEEP AIR IN
The oral tube has a one-way valve opened by air pressure, which
means the cap is designed to keep dirt and debris out of the tube and
valve, not to hold in pressure. (When you flip the cap over and press it
into the tube, however, it will let out pressure for deflation.)
So while it is good practice to keep the cap on the tube, it is not
necessary for maintaining your PFD’s pressure.
DEFLATING
Complete deflation is easiest when you are not wearing the PFD;
however, it is much easier to take off the PFD if you at least partially
deflate it while wearing.
WHILE WEARING
• Locate oral tube and remove its cap
• Turn cap over, using pointed end to press into the valve. This creates
the outlet for gas release
• Continuing to press cap end (which keeps your outlet open), use the
palm of your other hand to gently flatten the material against your
shoulders and chest, which moves pressure toward the outlet
