APPROVAL CONDITIONS AND CARRIAGE REQUIREMENTS  
Recreational - Approved for recreational use by the U.S. Coast Guard  
(USCG) as a Type II (Model MD3183), or Type V (Model MD3184)  
Personal Flotation Device (PFD). Neither are approved for water skiing  
or other high impact, high-speed activities. Model MD3184 has Type II  
performance but is approved as a Type V PFD because it has a built-in  
sailing harness that can cause injury if not properly used. A separate  
section titled “SAILING HARNESS” (p. 16) discusses requirements and  
features on the MD3184 only. USCG approval does not apply to the  
sailing harness because some of the risks associated with its use have  
not been evaluated.  
Commercial - Model MD3183 is a U.S. Coast Guard approved Type  
V inflatable PFD, approved ONLY WHEN WORN for use on uninspected  
commercial vessels less than 40 feet in length not carrying passengers  
for hire as a substitute for a Type II PFD when used in accordance with  
this owner’s manual.  
NOTE: MD3184 is not USCG approved for Uninspected Commercial  
Vessels.  
Conditions for Type V Approval in commercial applications:  
1. The MD3183 must be worn before getting underway and whenever  
above deck and not within an enclosed space to meet the carriage  
requirement.  
2. The operator of an uninspected commercial vessel is responsible for  
servicing and maintaining the MD3183 in good serviceable condition  
in accordance with this owner’s manual. See Care and Maintenance  
Instructions (p. 17) for servicing information.  
3. The operator of an uninspected commercial vessel is responsible for  
providing each person onboard with the safety information required  
for use of the MD3183. See page 2 for information.  
General - When fully inflated, this Inflatable PFD will provide Type II  
in-water performance. This Inflatable PFD will turn most wearers from a  
face down to a face up position and provide support suitable for offshore  
conditions. See page 9 for re-arming instructions.  
Inflatable PFDs are not approved for water skiing or other 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 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.  
NOTE TO UNINSPECTED COMMERCIAL VESSEL  
OPERATORS  
The operator of the vessel is required to provide the following user  
information to each person on board.  
Inflatable PFDs will not provide any buoyancy without being inflated.  
Follow these instructions to be sure your PFD is armed and donned  
correctly, and that you understand how to inflate the device.

WHY ARE PFDS REQUIRED SAFETY EQUIPMENT?  
Drownings are the leading cause of fatalities involving recreational and  
commercial vessels. 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 lbs (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  
2
Inflatable PFD Owner’s Manual  
 
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 can be inflated either  
automatically by 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. 3).  
INSTRUCTIONS FOR USE  
This manual supplies instructional, maintenance and safety information  
for both models (MD3183, MD3184). The model number is listed on the  
underside label.  
Uninspected Commercial Vessel Use  
This Inflatable PFD is not approved for “hot work” and care must be  
taken to avoid damage from abrasion and sharp objects.  
Component Inspection Instructions  
1) Examine the single point status indicator through the window panel  
(Fig. 1 and 2). Ensure the indicator is green. If the indicator is red, the  
mechanism has been fired or is incorrectly fitted (see Re-arming Your  
PFD, p. 9).  
NOTE: The single point status indicator must be green before  
proceeding.  
2) Undo the zipper on the wearer's left side, exposing the oral inflator.  
3) Ensure the oral-inflation dust cap is in the stowed position (Fig. 7).

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.  
4
Inflatable PFD Owner’s Manual  
 
For the non-harness model MD3183, the belt should fit below your  
rib cage adjusted to a tight personal fit.  
For the harness model MD3184, 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.  
Inflating Your Inflatable PFD  
FIgURe 3  
It is recommended that the following procedures be followed to inflate  
your Inflatable PFD:  
1) Manual Inflation  
Activate the inflation  
system by jerking firmly  
Automatic Inflator  
downward on the pull-tab  
(Fig. 4). The Inflatable PFD  
should fully inflate within 5  
seconds.  
FIgURe 4  
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  
Inflatable PFD Owner’s Manual  
5
 
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.  
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 Inflatable Devices  
3) Oral Inflation  
Properly armed and inspected  
FIgURe 5  
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.  
i. To orally inflate the Inflatable  
PFD, first ensure that each of the  
zippers (2) are completely opened.  
NOTE: Oral inflation may cause the Inflatable PFD to break-out  
suddenly (loudly) if any of the zippers are closed.  
ii. 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.  
Special Considerations for Inflatable Devices  
The Inflatable PFD might not be armed when needed, either knowingly  
or unknowingly. Inadvertant inflation causes several risks that you must  
address to avoid drowning. Much less common but also important are:  
6
Inflatable PFD Owner’s Manual  
 
1) Double inflation (CO cylinder inflation after full oral inflation) could  
2
damage the Inflatable PFD,  
2) Inflation when stored in a tight space could damage the Inflatable  
PFD, and  
3) The Inflatable PFD could inflate when you are in an awkward place  
or position.  
If this Inflatable PFD should inflate inadvertantly, a re-arm kit  
(MA7214) is required to re-arm the device.  
IMPORTANT: The Inflatable PFD should be re-armed according  
to the instructions (Re-arming Your PFD, p. 8).  
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

3) Examine the single point status  
indicator (Fig. 1 and 2). If the indicator is red, the mechanism has  
been fired and the inflator requires service (see Re-arming your PFD,  
p. 9).  
IMPORTANT: The single point status indicator must be green  
before proceeding.  
4) Your device is ready to be repacked (see Repacking p. 11).

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.

WARNING: CO inflation could over-pressurize and damage your  
2
Inflatable PFD if already fully inflated.  
Re-arming Your PFD  
NOTE: A valid re-arm kit (MA7214) is required for this procedure.  
1) Place the Inflatable PFD (Personal  
Flotation Device) on a smooth, flat  
surface and wipe off any water.  
Access the inflator by reaching under  
the cover and pull it toward you,  
turning the cell and cover inside-  
out to fully expose the inflator for

Inflatable PFD Owner’s Manual  
 
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 single point status indicator showing green.  
See Page 3 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 single point status indicator through the window  
panel, ensuring it is green. If the indicator is red, the mechanism  
requires service. See Re-arming Your PFD, p. 8.  
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 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. 11).  
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.  
Inflatable PFD Owner’s Manual

CAUTION: To avoid accidental inflation, don't allow the water  
to contact the hydrostatic inflator.  
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, p. 8.  
4) Annually - Perform the following at the beginning of each boating  
season, after inflation, or whenever the integrity of the Inflatable PFD  
is in doubt:  
i) Check all components for dirt or corrosion. Clean or replace, as  
neccessary. See Readiness Checklist (p. 4).  
ii) 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.  
iii) Perform the Oral Inflation Valve Test: See the Oral Inflation Valve  
Test in the Every Two (2) Months Care and Maintenance Instructions  
section.  
iv) Perform the Leak Test. See the Leak Test in the Every Two (2)  
Months Care and Maintenance Instructions section.  
v) Ensure the current date is not past the date on the inflator. If it  
is, replace the inflator (see Re-arming Your PFD, p. 8).  
vi) Ensure the single point status indicator is green (Fig. 1 and 2).  
vii) Record as an "Annual" inspection in permanent ink on the Care  
and Storage label, in the Date Maintained column.  
Repack the Inflatable PFD as outlined in the Repacking section (p. 11).  
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  
To avoid inflation, do not submerge the Inflatable PFD or directly spray  
the inflator. Hand wash or sponge down the Inflatable PFD in warm,  
soapy water. Rinse the PFD and inflator with clean water, using a clean  
rinse cloth. Hang the Inflatable PFD to dry on a plastic coat hanger. Do  
not dry clean.  
Always store your Inflatable PFD in a warm, dry place out of direct  
sunlight.  
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. 17). It should  
inflate quick and easily.  
Learn how it works by:  
• Activating the CO inflation system

• Using the oral inflator tube  
HOW DO YOU TEST YOUR PFD USING THE  
AUTOMATIC INFLATOR?  
The U.S.Coast Guard recommends that you purchase at least two spare  
re-arming kits (MA7214).  
1) To test your Inflatable PFD, you will need your fully armed Inflatable  
PFD, and re-arming kit (MA7214) 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, 4  
Inflatable PFD Owner’s Manual  
17  
 
inches or so, the Inflatable PFD should fully inflate automatically  
within 5 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.  
6) Deflate the Inflatable PFD by depressing the oral inflator valve (see  
Deflating the Inflatable PFD p. 7). Remove the used inflator.  
7) Let the Inflatable PFD dry thoroughly. Re-arm (p. 8) and Repack the  
PFD (p. 11).  
HOW DO YOU TEST YOUR PFD USING THE  
MANUAL INFLATOR?  
The U.S.Coast Guard recommends that you purchase at least two spare  
re-arming kits (MA7214).  
1) To test your Inflatable PFD, you will need your fully armed Inflatable  
PFD, and re-arming kit approved for your Inflatable PFD: MA7214.  
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).  
7) Let the Inflatable PFD dry thoroughly. Re-arm (p. 8) and Repack the  
PFD (p. 11).

HOW DO YOU TEST YOUR PFD USING THE ORAL  
INFLATOR?  
This test is not mandatory, however may be conducted using the  
following procedure.  
WARNING: Use only a previously fired hydrostatic inflator to  
perform this test. DO NOT test with a fully armed hydrostatic  
inflator as double inflation may occur, possibly resulting in cell  
damage.  
1) No spare parts or re-arming kits are needed to test 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.  
4) 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.  
5) Fully inflate the Inflatable PFD using the oral inflator.  
6) 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.  
7) 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).  
8) Let the Inflatable PFD dry thoroughly. Re-arm (p. 8) and Repack the  
PFD (p. 11).  
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 Owner’s Manual  
19  
 
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

Inflatable PFD Owner’s Manual  
 
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. 33).  
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 single point status  
indicator before each use.  
2) Get in the habit of re-arming the  
FIgURe 33  
inflation mechanism right after  
each inflation.  
Help position  
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  
Inflatable PFD Owner’s Manual

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.
