1 MUSTANG SURVIVAL / OWNER’S MANUAL – MD3151 / MD3153 / MD3154 / INFLATABLE PFD
INFLATABLE PFDS
Inflatable personal flotation devices (PFDs) are special devices
in that the flotation of the wearer is not derived from inherently
buoyant materials. In order for them to do their job, you, the wearer,
must do yours! This means you have the responsibility to ensure
you are familiar with the operation and maintenance requirements
of your inflatable PFD! You must also be aware of the limitations of
the device and know that it is not approved under the Small Vessel
Regulations for certain boating activities.
READ YOUR OWNER’S MANUAL AND THE INFORMATION LABELS ON YOUR PFD!
IT COULD SAVE YOUR LIFE!
AIRLINE OPERATOR POLICY ON CARRIAGE OF INFLATABLE PFDs
AND CO2CARTRIDGES
Please be aware that regulations may apply to the air transport of this
product. With the approval of the aircraft operator, carbon dioxide
cylinder(s) may be carried by a passenger or crew in checked or
carry-on baggage. Please consult airline operator policy.
APPROVAL CONDITIONS AND CARRIAGE REGULATIONS
This inflatable PFD is approved by Transport Canada for use as a
Type II (MD3153 and MD3154) or Type III (MD3151) personal flotation
device. 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 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.
The MD3154 has a built-in sailing harness that can cause injury if
not properly used. When worn, used, and serviced according to
this owner’s manual, these PFDs can greatly increase your chances
of survival in the water. They should always be fitted with the
appropriate, unpunctured, and fully functional inflation cartridge,
or be worn fully inflated. They are NOT for white water paddling or
personal watercraft use. PFDs fitted with an automatic inflator are not
permitted for sailboarding activities. In order to meet the equipment
carriage requirements of the small vessel regulations, these PFDs
must be worn by an adult, in the case of an open boat or on deck or in

2
the cockpit in any other type of boat, or readily available to any other
adult occupant while below deck.
A separate section titled “Sailing Harness”, p. 18, discusses
requirements and features on the MD3154 only.
Transport Canada approval does not apply to the sailing harness
because some of the risks associated with its use have not been
evaluated.
MANDATORY CARRIAGE REQUIREMENTS
The Small Vessel Regulations require that you carry on board a
Transport Canada approved personal flotation device, which bears a
mark or label indicating the approval and is of an appropriate size for
each person on board. 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 non-functional oral inflation tube. Unless
worn inflated, this PFD must also be properly armed with a full CO2
cylinder, inflation system status indicator, 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.
WHAT IS AN INFLATABLE PFD?
While traditional PFDs are inherently buoyant, inflatable PFDs
rely entirely on inflation for buoyancy. Uninflated, your PFD is
a comfortable slim collar that can be inflated at any time with a
33-gram carbon dioxide (CO2) gas cylinder. The inflatable PFD is
designed to oer maximum mobility with minimum bulk. The MD3153
and MD3154 inflatable PFDs can be inflated either automatically by
water immersion, manually by jerking a pull-tab, or orally by mouth.
The MD3151 inflatable PFD can be inflated manually by jerking the
pull-tab or orally by mouth. It is recommended that you familiarize
yourself with the procedures outlined in Instructions for Use, p. 3.

COMPONENT INSPECTION INSTRUCTIONS
1. Look through the inflator window panel (Fig. 1). Ensure the
indicator is green. If the single point status indicator (Fig.
2 for MD3153 and MD3154, or Fig. 2a for MD3151) is red, the
mechanism has been fired or is incorrectly fitted (see Re-arming
Your PFD, p. 9).
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 cap is in the stowed position
(Fig. 7 on p. 8).
4. Ensure the single point status indicator is green and the pull-
tab lanyard is hanging on the outside; secure the zippers on the
Inflatable PFD (see Repacking Your PFD, p. 14).
5. Ensure the current date is not past the date on the inflator.
If it is, replace the inflator (see Re-arming Your PFD, p. 9).
READINESS CHECKLIST
Check your PFD and ensure all of the checkpoints listed below are
true before use.
¨Single point status indicator is green (Fig. 2 or 2a).
¨Ensure the current date is not past the date on the inflator. If it is,
replace the inflator (see Re-arming Your PFD, p. 9).
¨Ensure both zipper stops are in place under Velcro™ tab (Fig. 1).
¨All zippers, Velcro™, and waist buckle are securely fastened.
¨Oral inflation cap is in the stowed position (Fig. 7).
¨PFD is not twisted.
¨Ensure the inflation pull-tab is hanging on the outside (Fig. 31).

FIGURE 3
SIZING AND FIT
This PFD provides a minimum of 150 Newtons (33.7 pounds) of
buoyancy when inflated and is designed for wearers over 16 years of
age, with a chest range of 76-132 cm (30-52 inches) and weighing
over 36 kg (80 pounds).
PUTTING ON (DONNING) YOUR PFD
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 MD3153 and
MD3151, the belt should fit below your rib cage adjusted to a
tight personal fit. For the harness model MD3154, the bottom of
the belt must always be worn at least 5 cm (2 inches) above the
lowest rib and adjusted to a tight personal fit.
2. Put the 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.
DONNING YOUR PFD

6
INFLATING YOUR PFD
Follow the below procedures to inflate your PFD:
1. Manual Inflation
Activate the inflation system by
jerking firmly downward on the pull-
tab (Fig. 4). The PFD should fully
inflate within five seconds.
2. Automatic Backup Inflation
(For models MD3153 and
MD3154 only)
When the inflator is lowered more
than about four inches in the water,
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 carbon dioxide (CO2) cylinder,
which is now punctured so that
the gas instantly fills the PFD. Total
buoyancy is normally reached within
four to five seconds.
Once the PFD is inflated, the CO2will 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.
SEE SPECIAL CONSIDERATIONS FOR INFLATABLE DEVICES.

3. Oral Inflation
Properly armed and inspected
inflatable PFDs will inflate when
manually or automatically activated.
However, you can fully inflate the
PFD by mouth (Fig. 5) should
inflation not occur, or if you are in a
non-emergency situation.
• To orally inflate the Inflatable PFD,
first ensure that both of the two
zippers are completely opened.
• Locate the oral inflation tube by
opening the wearer’s left front
panel. Remove the cap from the
end of the oral tube and blow
into the tube until the PFD is
fully inflated.
ORAL INFLATION MAY CAUSE THE INFLATABLE PFD TO BREAK OUT SUDDENLY
(LOUDLY) IF ANY OF THE ZIPPERS IS CLOSED.
SPECIAL CONSIDERATIONS FOR INFLATABLE DEVICES
The inflatable PFD might not be armed when needed, either
knowingly or unknowingly. Inadvertent inflation causes several risks
that you must address to avoid drowning. Much less common but also
important are:
1. Double inflation (CO2cylinder inflation after full oral inflation)
could damage the PFD.
2. Inflation when stored in a tight space could damage the PFD.
3. The PFD could inflate when you are in an awkward place or
position.
4. If this PFD should inflate inadvertently, a re-arm kit is required to
re-arm the device (MA7214 for models MD3153 and MD3154, and
MA3181 for model MD3151).
THE INFLATABLE PFD SHOULD ALWAYS BE RE-ARMED ACCORDING TO THE
INSTRUCTIONS (SEE RE-ARMING YOUR PFD, P. 9).
FIGURE 5 ORAL INFLATION

DEFLATING YOUR PFD
1. To deflate the PFD, reverse the oral-inflation tube cap and insert
it into the valve or depress the valve with your fingertip. The cap
will not lock in the deflate position so it is necessary to hold it in
place (Fig. 6).
2. Gently squeeze the PFD until all air or gas has been expelled. To
avoid damage, do not wring or twist the PFD. Put the cap back in
its stowed position on the oral inflation tube (Fig. 7).
ENSURE ALL AIR HAS BEEN REMOVED FROM THE PFD.
3. Examine the single point status indicator (Fig. 2 or 2a on p. 3). If
the indicator is red, the mechanism has been fired and the inflator
requires service (see Re-arming Your PFD, p. 9).
THE SINGLE POINT STATUS INDICATOR MUST BE GREEN BEFORE PROCEEDING.
4. Your device is ready to be repacked (see Repacking Your PFD,
p. 14).
