To secure loose ends:
3. Adjust the waist belt for a snug fit using the side buckle on the belt.
4. Reposition the plastic sliding loop as far back as possible to keep the free end from
hanging loose.
5. Wrap and tuck any remaining loose strap around belt.
6. Recheck loose ends and readjust as needed.
WARNING: Do not wear Inflatable PFDs under clothing as the inflation
could be restricted or you could be injured.
Removal Instructions
In some instances, quick removal of the PFD may be necessary for your safety.
Simply unfasten the front buckle, and remove the vest like a jacket.
In-water removal of your PFD may require deflation through the oral tube to access and open
the front buckle (see Deflating the Inflatable PFD, page8).
Inflating Your Inflatable PFD
It is recommended that the following procedures be
followed to inflate your Inflatable PFD:
1. Manual Inflation – Activate the inflation system
by jerking firmly downward on the pull-tab (Figure
4). The Inflatable PFD should fully inflate within 5
seconds.
2. Automatic Backup Inflation – When
the inflator is lowered more than about
4 inches in the water, then the hydrostatic valve opens
and lets the water meet the water sensitive element
that in turn releases a stainless steel coil spring. The
spring then drives a needle into the end of the gas
cylinder, which is now punctured so that the gas
instantly fills the life jacket. Total buoyancy is normally
reached within 4-5 seconds.
Permeation Loss Information
Permeation loss is greater when the PFD is inflated with carbon dioxide (CO
2
gas) than with
air. When inflated, the CO
2
gas used to inflate the PFD will slowly escape through the fabric
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 prolonged immersion.
