INFLATING
Your flotation device inflates manually, orally, and (for MD4032 only)
automatically. No matter how your flotation device inflates, it can
always be topped up orally – extending your ability to keep afloat.
The inflation instructions below use ‘left’ and ‘right’ assuming you are
wearing the flotation device during inflation – so your left or right is
also the device’s.
1. Manually
Activate the inflation system by
jerking firmly downward on the
pull-tab (Fig. 3). The flotation device
should fully inflate within
five seconds.
2. Automatically as backup
(MD4032)
Inflation will occur automatically
within 10 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
(Fig. 8 and 9) to inflate the
flotation device.

Automatic Devices,” next page.
3. Orally
To orally inflate the flotation
device, first locate the oral inflation
tube by opening your left front
panel. Remove the cap from the
end of the oral tube and blow into
the tube until the flotation device
is fully inflated (Fig. 4). Place the
oral tube cap back in the stowed
position (Fig. 6).
