APPROVAL CONDITIONS AND CARRIAGE REGULATIONS
This Inflatable PFD is approved by the U.S. Coast Guard (USCG) for use as
a Type III (Model MD3081), Type V (Model MD3082) Personal Flotation
Device (PFD), Type II (Model MD3083), and Type V (Model MD3084)
Personal Flotation Device (PFD). Models MD3082 and MD3084 have
Type III and Type II performance respectively but are approved as Type
V PFDs because they have built-in safety harnesses that can cause injury
if not properly used. A separate section titled “SAILING HARNESS” (p.
13) discusses requirements and features on the MD3082 and MD3084
only. USCG approval does not apply to the sailing harness because some
of the risks associated with its use have not been evaluated. It is not
approved for water skiing or other high impact, high-speed activities.
This Inflatable PFD was designed to be more comfortable and less
restrictive to wear than inherently buoyant PFDs. When worn, used, and
serviced according to this owner’s manual, this Inflatable PFD can greatly
increase your chances of survival in the water. Not recommended for
non-swimmers or weak swimmers. Users of inflatable PFDs must be at
least 16 years old.
MANDATORY CARRIAGE REQUIREMENTS
Federal regulations in 33 CFR 175-1993 require you to carry Coast Guard
approved personal flotation devices (PFDs) legibly marked with the Coast
Guard approval number which are in good and serviceable condition
and are the correct size for each person on board. To be considered
serviceable, this Inflatable PFD shall not exhibit deterioration that could
diminish its performance such as broken or deformed hardware, detached
webbing, rotted structural components, air leaks, or nonfunctional oral
inflation tube. Unless worn inflated, this Inflatable PFD must also be
properly armed with a full CO cylinder, inflation system status indicator,
2
and an accessible manual inflation lanyard. A PFD which is “approved
only when worn” or “required to be worn” must be worn under the
specified conditions.

Inflatable PFD Owner’s Manual
WHAT IS AN INFLATABLE PFD?
While traditional PFDs are inherently buoyant, inflatable PFDs, rely
entirely on inflation for buoyancy. Uninflated, the Inflatable PFD is a
comfortable slim collar that can be inflated at any time with a 33-gram
CO gas cylinder. The Inflatable PFD is designed to offer maximum
2
mobility with minimum bulk. The Inflatable PFD (MD3081 and MD3082)
can be inflated either manually by jerking a pull-tab, or orally (by
mouth). The Inflatable PFD (MD3083 and MD3084) can be inflated either
automatically during water immersion, manually by jerking a pull-tab, or
orally by mouth. It is recommended that you familiarize yourself with the
procedures outlined in INSTRUCTIONS FOR USE (p. 2).
INSTRUCTIONS FOR USE
This manual supplies instructional, maintenance and safety information
for all models (MD3081, MD3082, MD3083, and MD3084) unless
specified otherwise. The model number is listed on the underside label.
Congratulations on your Inflatable PFD purchase.
Component Inspection Instructions
1) Examine the service indicator through the window panel (Figs. 1 and
2). Ensure the service indicator is green. If the service indicator is red,
the mechanism has been fired or is incorrectly fitted (see Re-arming
Your PFD (for your model)).
NOTE: The service indicator must be green before proceeding.
2) Undo the Velcro™ strips along both sides of the PFD.

Inflatable PFD Owner’s Manual
Your Inflatable PFD is ready for use if all applicable boxes are checked.
NOTE: Contact your Mustang Dealer if you have any concerns
about the readiness of your Inflatable PFD.
Sizing and Fit
This PFD provides a minimum of 33.7 lbs of buoyancy when inflated and
is designed for wearers over 16 years of age, with a chest range of 30-52
inches (76-132 cm) weighing over 80 pounds (36 kg).
Donning Instructions
It is important that the Inflatable PFD is properly adjusted to fit the
person wearing it. An incorrect fit or improper fastening of attachments
could impede its effectiveness.
1) All belts and straps are already threaded correctly and only need to
be adjusted for fit.
For the non-harness models MD3081 and MD3083, the belt should
fit below your rib cage adjusted to a tight personal fit.
For the harness models MD3082 and MD3084, the bottom of the belt
must always be worn at least 2 inches (5 cm) above the lowest rib
and adjusted to a tight personal fit.
2) Put the Inflatable PFD on just like a jacket (Fig. 3) and fasten the
front buckle. Adjust the waist belt using the side buckle on the belt
and secure the belt’s loose end in the belt loop.
WARNING: Do not wear Inflatable PFDs under clothing as the
inflation could be restricted or you could be injured.
FIGURE 3

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 (Fig. 4). The Inflatable PFD should fully inflate within 5 seconds.
FIGURE 4
Manual Inflator
Automatic Inflator
MD3081 and MD3082 MD3083 and MD3084
2) Automatic Backup Inflation (MD3083 and MD3084)
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 cylinder
2
(Figs. 9 and 11) to inflate the Inflatable PFD.
Information
When inflated, the carbon dioxide (CO gas) used to inflate the PFD
2
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 very prolonged
immersion.
IMPORTANT: See Special Considerations for Automatic Devices
3) Oral Inflation
Properly armed and inspected Inflatable PFDs will inflate when
manually or automatically activated. However, you can fully inflate
the Inflatable PFD by mouth (Fig. 5) should inflation not occur, or if
you are in a non-emergency situation. To orally inflate the Inflatable
5
Inflatable PFD Owner’s Manual
PFD, first locate the oral inflation tube by opening the wearer ’s left
front panel of the Inflatable PFD. Remove the dust cap from the end
of the oral tube and blow into the tube until the Inflatable PFD is
fully inflated.
WARNING: Avoid double inflation (CO cylinder inflation after
2
full oral inflation) as it could damage the PFD.
FIGURE 5
Special Considerations for Automatic Devices
(MD3083 and MD3084)
The Inflatable PFD might not be armed when needed, either knowingly
or unknowingly. Premature automatic inflation causes several risks
that you must address to avoid drowning. Much less common but also
important are:
WARNING: Avoid double inflation (CO cylinder inflation after
2
full oral inflation) as it could damage the PFD.
1) Inflation when stored in a tight space could damage the PFD, and
2) The PFD could inflate when you are in an awkward place or position.
Premature inflation may occur in certain conditions, including when
the device is subjected to: heavy splashing, high humidity, heavy fog,
and heavy rain.
Care and attention should be taken to ensure that when the device
is used in these types of conditions, auto-inflation does not occur
prematurely.
Inflatable PFD Owner’s Manual

If this PFD should inflate prematurely, a re-arm kit (MA7202) is
required to re-arm the device.
IMPORTANT: The Inflatable PFD should be re-armed according
to the instructions (Re-arming Your PFD (MD3083 and
MD3084) p. 10).
Deflating the Inflatable PFD
1) To deflate the Inflatable PFD, reverse the oral-inflation tube dust cap
and insert it into the valve or depress valve with fingertip. The dust
cap will not lock in the deflate position so it is necessary to hold it in
place (Fig. 6).
2) Gently squeeze the Inflatable PFD until all air or gas has been
expelled. To avoid damage; do not wring or twist the Inflatable PFD.
Put the inflation tube dust cap back in its stowed position on the
oral inflation tube (Fig. 7).
3) Examine the service indicator (Figs. 1 and 2). If the service indicator
is red, the mechanism has been fired or is incorrectly fitted and the
inflator requires service (see Re-arming your PFD (for your model)).
NOTE: The service indicator must be green before proceeding.
4) Your device is ready to be repacked (see Repacking p. 13).

Sailing Harness
Models with a sailing harness (MD3082 and MD3084) are designed to
prevent the user from falling overboard when used with a tether with
an under-load quick-release hook and have been designed and tested
in accordance with Offshore Racing Council (ORC) requirements. Care
and attention must be taken to ensure that the harness is used and
maintained correctly. The harness is designed to be worn by persons at
least 5 feet 5 inches tall (165 cm). The harness should be worn as high
on the chest as possible, but in all cases, at least 2 inches (5 cm) above
the lowest rib measured from the bottom of the belt and should not be
used if it does not fit in this manner. Adjust the harness using the strap
adjuster so that the harness is as snug as tolerable.
Failure to adjust the harness properly could result in injury.
When attached to the boat use a tether of less than 6 feet 6 inches (2 m)
in length with quick-release under-load hardware (Fig. 17).
Ensure that a tether is secured to both D-rings. When not in use, the
D-rings can be pushed under the lapels.
Warning: Use of a sailing harness to prevent falls overboard
presents several risks. In case of capsizing or sinking, the boat
may take you down. As such, ensure that any tether used has
Inflatable PFD Owner’s Manual
14
quick-release under-load hardware. This harness has not been
designed for fall arrest, lifting or climbing and should not be
relied upon in any of these instances.
US Coast Guard approval does not apply to this harness and the
potential for injury has not been assessed.

IS YOUR PFD IN GOOD AND SERVICEABLE
CONDITION?
Check your Inflatable PFD between outings to be sure that it is properly
armed; that it is free of rips, tears or holes; that all seams are securely
sewn; and that the fabric, straps and hardware are still strong (See
Readiness Checklist, p. 3). Inspect the inflatable portion of the Inflatable
PFD in accordance with the CARE AND MAINTENANCE INSTRUCTIONS.
CARE AND MAINTENANCE INSTRUCTIONS
Check the following at the intervals listed below.
1) Each Use: Examine the service indicator through the window panel,
ensuring it is green. If the service indicator is red, the mechanism has
been fired or is incorrectly fitted. See Re-arming Your PFD (for your
model).
2) Every Three (3) Months: Leak Test: Every three months the Inflatable
PFD should be tested for general leakage by orally inflating your
Inflatable PFD until firm and let stand overnight. A leaking Inflatable
PFD will not hold its firmness and should be replaced. If your
Inflatable PFD leaks, take it to your Mustang dealer for evaluation
and/or servicing. Repack the Inflatable PFD as outlined in the
15
Inflatable PFD Owner’s Manual
Repacking section (p.13).
3) Annually - Perform the following at the beginning of each boating
season, after cell inflation, or whenever the integrity of the inflatable
cell is in doubt:
i) Check all components for dirt or corrosion. Clean or replace.
ii) Visually examine your Inflatable PFD for damage or excessive
abrasion, wear, tear or contamination. Particular attention must be
paid to the stitching. If in doubt, send it to your Mustang dealer for
evaluation and/or servicing.
iii) To check the oral inflation valve, fully inflate the Inflatable PFD
and hold valve under water. If bubbles appear, deflate and re-inflate
to test again. Should the leak persist, take your Inflatable PFD to
your Mustang dealer for evaluation and/or servicing.
iv) Check that the CO cylinder/bayonet assembly has not been
2
pierced. Ensure the o-ring is in place and the sensor ring is intact
on the bayonet (Fig. 10). If necessary, replace with 33-gram CO
cylinder/bayonet assembly (contained in appropriate re-arm kit).
2
v) Record as an "Annual" inspection in permanent ink on the Care
and Storage label, in the Maintenance Date column.
Re-assemble inflation system parts and repack the Inflatable PFD as
outlined in the Repacking section (p.13).
Warning: If you are not confident in the self-inspection and
servicing of your Inflatable PFD in accordance with these
instructions, take your Inflatable PFD to a Mustang dealer
for professional servicing or contact Mustang Survival (see
contact information on back of manual).
Cleaning and Storing of Your Inflatable PFD

WHY ARE PFDS REQUIRED SAFETY EQUIPMENT?
Drownings are the leading cause of fatalities involving recreational
boating. A PFD provides flotation to help keep your head above water,
help you to stay face up in the water, and increase your chances for
survival and rescue. Most adults only need an extra 7 to 12 pounds (3.2
to 5.5 kg) of flotation to keep their heads above water. The proper size
PFD will properly support the weight of the wearer.
Since this Inflatable PFD does not have inherent buoyancy, it provides
flotation only when inflated. Familiarize yourself with the use of this
Inflatable PFD so you know what to do in an emergency.
HOW AND WHY TO TEST YOUR PFD
Inflate your Inflatable PFD and try it out in the water to:
·
Make sure it floats you:
• Comfortably (when worn properly)
• Adequately for expected wave conditions (body shapes/
densities affect performance)
·
Make sure it works:
• A flow of bubbles should not appear (see CARE AND
17
Inflatable PFD Owner’s Manual
MAINTENANCE INSTRUCTIONS for leak tests p. 14). It should
inflate quick and easily.
·
Learn how it works by:
• Activating the CO inflation system
2
• Re-arming the CO inflation system
2
• Using the oral inflator tube
To check the manual inflation system (with CO cylinder/bayonet
2
assembly removed); determine that the CO cylinder piercing pin moves
2
freely when pushing up on the lever arm by pushing down on the pins
and releasing the pins followed by the lever arm (for MD3081 and
MD3082 see Fig. 9 and for MD3083 and MD3084 see Fig. 12). Repeat
this several times to check the manual inflation system.
MODELS MD3083 and MD3084
The U.S.Coast Guard recommends that you purchase two automatic
re-arming kits (MA7202). One kit is to be used immediately in testing
the automatic inflation system (see HOW DO YOU TEST YOUR PFD USING
THE AUTOMATIC INFLATOR?, p. 18) and the other to carry on board as a
spare.
The U.S. Coast Guard recommends you test the automatic inflation
system in the water at the beginning of each boating season. By
doing this, you demonstrate that the automatic inflation system is still
working properly and reduce the likelihood of premature inflation and its
associated dangers.
HOW DO YOU TEST YOUR PFD USING THE
AUTOMATIC INFLATOR? (MD3083 and MD3084)
1) To test your Inflatable PFD, you will need your fully armed Inflatable
PFD, and re-arming kit (MA7202) approved for your Inflatable PFD
2) Put on the Inflatable PFD.
3) Get into shallow water, just deep enough that you can stand with
your head above the surface. Once the inflator is underwater the
Inflatable PFD should fully inflate automatically within 10 seconds.
4) See if the Inflatable PFD will float you on your back or just slightly
back of vertical. In a relaxed floating position, verify that your mouth
Inflatable PFD Owner’s Manual
18
is well above the water’s surface. Note the effect of where you hold
your legs on how you float.
5) Get out of the water and remove the Inflatable PFD. Remove the
used CO cylinder/bayonet assembly and the used bobbin from the
2
Inflatable PFD inflator.
Deflate the Inflatable PFD by depressing the oral inflator valve (see
Deflating the Inflatable PFD p. 7).
6) Let the Inflatable PFD dry thoroughly. Re-arm and Repack the PFD (p.
13).
HOW DO YOU TEST YOUR PFD USING THE
MANUAL INFLATOR?
1) To test your Inflatable PFD, you will need your fully armed Inflatable
PFD, and re-arming kit approved for your Inflatable PFD: MA7203
for models MD3081 and MD3082, MA7202 for models MD3083 and
MD3084.
2) Put on the Inflatable PFD.
3) Actuate the inflation system by jerking firmly downward on the
pull-tab. The Inflatable PFD should fully inflate within 5 seconds.
4) Get into shallow water, just deep enough that you can stand with
your head above the surface.
5) See if the Inflatable PFD will float you on your back or just slightly
back of vertical. In a relaxed floating position, verify that your mouth
is well above the water’s surface. Note the effect of where you hold
your legs and how you float.
6) Get out of the water and remove the Inflatable PFD. Completely
deflate the Inflatable PFD using the oral inflator (see Deflating the
Inflatable PFD p. 7). Remove the CO cylinder/bayonet assembly from
2
the inflator.
7) Let the Inflatable PFD dry thoroughly. Re-arm and Repack the PFD (p.
13).
HOW DO YOU TEST YOUR PFD USING THE ORAL
INFLATOR?
19
Inflatable PFD Owner’s Manual
1) No spare parts or re-arming kits are needed to test an Inflatable PFD.
2) Remove the CO cylinder/bayonet assembly to prevent inadvertent
2
inflation, which could potentially damage the Inflatable PFD. Inspect
the cylinder to confirm it is unused (Fig. 11). Unscrew and remove
the cap and the bobbin (MD3083 and MD3084 only). Otherwise the
bobbin will disintegrate during water immersion.
3) Put on the Inflatable PFD.
4) Get into shallow water, just deep enough that you can stand with
your head above the surface.
5) If you are a weak swimmer or non-swimmer, inflate the Inflatable
PFD partially so that you are supported well enough to be able
to complete inflation without touching bottom, either orally or
manually. Note this level of inflation because it is the minimum
needed for you to safely use this Inflatable PFD.
6) Fully inflate the Inflatable PFD using the oral inflator.
7) See if the Inflatable PFD will float you on your back or just slightly
back of vertical. In a relaxed floating position, verify that your mouth
is well above the water’s surface. Note the effect of where you hold
your legs on how you float.
8) Get out of the water and remove the Inflatable PFD. Completely
deflate the Inflatable PFD using the oral inflator.
9) Let the Inflatable PFD dry thoroughly. Re-arm (for your model) and
Repack the PFD (p. 13).
WEAR YOUR PFD
In approximately 80 percent of all boating fatalities, the victims were not
wearing a PFD. Most fatal accidents happen on calm sunny days. This
Inflatable PFD is much more comfortable to wear than other PFD types.
Get into the habit of wearing this Inflatable PFD.
Non-swimmers and children especially should wear a hybrid or non-
Inflatable PFD at all times when on or near the water.
HYPOTHERMIA
Prolonged exposure to cold water causes a condition known as

hypothermia - a substantial loss of body heat, which leads to exhaustion
and unconsciousness. Most drowning victims first suffer from
hypothermia. The following chart shows the effects of hypothermia: how
hypothermia affects most adults.

PFDs can increase survival time because they allow you to float without
using energy treading water and because of their insulating properties.
Naturally, the warmer the water, the less insulation you will require.
When operating in cold waters [below 60°F (15.6°C)] you should
consider using a coat or jacket style PFD or a Type V Thermal Protective
PFD as they cover more of the body than the vest or belt style PFDs.
Some Points to Remember About Hypothermia Protection:
1) Always wear your Inflatable PFD. Even if you become incapacitated
due to hypothermia, the Inflatable PFD will keep you afloat and
greatly improve your chances of rescue.
2) Do not attempt to swim unless it is to reach a nearby craft, fellow
survivor, or a floating object on which you can lean or climb.
Swimming increases the rate of body heat loss. In cold water, drown-
proofing methods that require putting your head in the water are
not recommended. Keep your head out of the water. This will greatly
lessen heat loss and increase your survival time.
3) Use the standard H.E.L.P. position when wearing an Inflatable PFD,
drawing the legs up to a seated position, because doing so will help
you conserve body heat (Fig. 18).
4) Keep a positive attitude about your survival and rescue. This will
improve your chances of extending your survival time until rescued.

Inflatable PFD Owner’s Manual
Your will-to-live does make a difference!
5) If there is more than one person in the water, huddling is
recommended while waiting to be rescued. This action tends to
reduce the rate of heat loss and thus increase the survival time.

EACH OF THESE DEVICES IS INTENDED TO HELP
YOU SAVE YOUR OWN LIFE
For your Inflatable PFD to function properly, follow these suggestions to
verify that it fits, floats, and remains in good condition.
1) Check the inflation mechanism status indicators before each use.
2) Get in the habit of re-arming the inflation mechanism right after
each inflation.
3) Try your wearable Inflatable PFD on and adjust it until it fits
comfortably in and out of the water.
4) Mark your Inflatable PFD with your name if you are the only wearer.
5) Do not alter your Inflatable PFD. If it doesn’t fit properly, get one that
does. An altered device is no longer Coast Guard approved.
6) Your Inflatable PFD is not intended for use as a fender or kneeling
pad.
7) If your Inflatable PFD is wet, allow it to dry thoroughly before storing
it. Store it in a well-ventilated area.
8) Do not dry your Inflatable PFD in front of a radiator or other source
of direct heat.

ADDITIONAL INFORMATION
If you need more information about PFDs and safe boating, contact your
state boating authority, U.S. Coast Guard Auxiliary, U.S. Power Squadron,
Red Cross, or your nearest unit of the U.S. Coast Guard. To find out about
free boating courses in your area call 1-800-336-BOAT (in Virginia, call
800-245-BOAT).
DO NOT ATTACH PFDs TO YOUR BOAT
Each PFD has straps, hooks, buckles, or other means for securing the
device in place on the wearer. Some PFDs also incorporate decorative
d-rings or tabs. Such items are not to be used to attach the device
to the boat. Attaching the device to the boat will not permit it to perform
as intended.
NOTE: Models MD3082 and MD3084 have built-in sailing
harnesses intended for attaching to boats with quick-release
under-load tethers secured to both d-rings (see Sailing Harness p.
14). Do not attach the MD3082 and MD3084 to boats using any
other means.
