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 lb (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.  
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 (MD3085) can be  
inflated either manually by jerking a pull-tab, or orally (by mouth). The  
Inflatable PFD (MD3087) 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 (MD3085 and MD3087) unless specified otherwise. The  
model number is listed on the underside label.

FIGURE 2  
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. 3). The Inflatable PFD should fully inflate within 5 seconds.  
FIGURE 3  
Manual Inflator  
Automatic Inflator  
MD3085  
MD3087

Inflatable PFD Owner’s Manual  
 
2) Automatic Backup Inflation (MD3087)  
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. 8 and 10) 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. 4) should inflation not occur, or if  
you are in a non-emergency situation. To orally inflate the Inflatable  
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.  
Place the oral inflator dust cap back in the stowed position (Fig. 6).  
WARNING: Avoid double inflation (CO cylinder inflation after  
2
full oral inflation) as it could damage the PFD.  
FIGURE 4  
Inflatable PFD Owner’s Manual

Special Considerations for Automatic Devices  
(MD3087)  
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.  
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 (MD3087) 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. 5).  
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. 6).  
3) Examine the service indicator (Fig. 1). 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)).

Usage Below Freezing  
When the temperature is below freezing, the Inflatable PFD should  
be worn partially inflated because a fully discharged cylinder may not  
quickly or adequately inflate your Inflatable PFD. Under these conditions  
use the oral inflator to adequately top-up the PFD, after CO inflation.

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. 4). Inspect the inflatable portion of the Inflatable  
PFD in accordance with the CARE AND MAINTENANCE INSTRUCTIONS.  
CARE AND MAINTENANCE INSTRUCTIONS  
Federal Regulations require Coast Guard approved personal flotation  
devices (PFDs) that are legibly marked with the Coast Guard approval  
number, are in good and serviceable condition, and are the correct size  
for each person on board. It is the responsibility of the operator to be  
sure this PFD is in serviceable condition. To be considered serviceable,  
this 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 inflators. Unless  
worn inflated, this PFD must also be properly armed with a cylinder  
installed in the inflator, and service indicator showing green. See Page 2  
Inflatable PFD Owner’s Manual  
14  
 
for instructions. Failure to follow these instructions rigorously could result  
in a non-functioning PFD causing injury or death.  
Check the following at the intervals listed below.  
1) Before Each Use:  
i) Examine the service indicator through the window panel,  
ensuring it is green. If the indicator is red, the mechanism requires

ii) Ensure the manual pull-tab is accessible.  
iii) Visually examine your Inflatable PFD for damage or excessive  
abrasion, wear, tear or contamination. Particular attention must be  
paid to the stitching, straps and hardware. If in doubt, send it to your  
Mustang dealer for evaluation and/or servicing.  
2) Every Two (2) Months:  
i) Leak Test: The Inflatable PFD should be tested for general leakage  
by orally inflating your Inflatable PFD until firm and let stand for 16  
hours. 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 Repacking section (p. 13).  
ii) Oral Inflation Valve Test: To check the oral inflation valve, fully  
inflate the Inflatable PFD using the oral inflator 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.  
CAUTION: To avoid accidental inflation, don't allow the water  
to contact the inflator (MD3087).  
iii) Perform a thorough visual examination. See Readiness  
Checklist (p. 4).  
Perform these tests more often if exposed to potential damage or  
used in extreme conditions.  
3) After Each Inflation - Re-arm the Inflatable PFD. See Re-arming  
Your PFD (your model), p. 8 or 10.  
4) Annually - Perform the following at the beginning of each boating

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  
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 MD3085 see Fig.  
8 and for MD3087 see Fig. 11). Repeat this several times to check the  
manual inflation system.  
17  
Inflatable PFD Owner’s Manual  
 
MODEL MD3087  
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? (MD3087)  
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  
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  
model MD3085, MA7202 for model MD3087.  
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?  
1) No spare parts or re-arming kits are needed to test your 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. 10). Unscrew and remove  
the cap and the bobbin (MD3087 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, orally inflate the  
Inflatable PFD partially so that you are supported well enough to be  
able to complete inflation without touching bottom. 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. 16).  
4) Keep a positive attitude about your survival and rescue. This will  
improve your chances of extending your survival time until rescued.  
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; or call the free  
boating course number1-800-336-BOAT (in VA, call 800-245-BOAT).  
DO NOT ATTACH PFD’S 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.
