INTRODUCTION
Roaring Forties Lifejackets or Personal Flotation Devices (PFDs) are essentially survival equipment and as such they should be
properly stored, maintained & handled. This Equipment may not be suitable for all situation and the life of the wearer, apart
from the physical condition of the wearer may well depend on the water condition, the condition of the PFD and it’s attachments.
This manual provides information for the inspection, testing and maintenance of SMA 2750 series of Personal Flotation Devices.
These series are approved to the Australian Standard AS1512 as a TYPE 1 PFD for persons weighing 40kg and above.
Any assistance required in regard to the manual should be directed to:
Safety Marine Australia Pty Ltd
P.O. Box 1121
Moorabbin

AUSTRALIA
DESCRIPTION
SMA 2750 SERIES are designed to provide sufficient buoyancy to turn an unconscious person face upwards within 5 seconds
of immersion. Most adults require less than 5kg of flotation to keep their heads above water. However, this PFD will provide a
minimum buoyant force of 28.3kg (278 Newtons) when it is fully inflated.
SMA2750 is very light weight without the harness and other attachments. However, the Essential Services model such as the
Victorian CFA, Coast Guard & Melbourne Metropolitan Fire Brigade etc. has additional attachments such as the harness, J
knife and a detachable pocket containing a sewed on lifeline. Both ends of the lifeline have Makefast snap hooks and it weighs
about 510g. The total weight of the SMA275 model is approximately 2.28 kg
SMA2750 will fit teenager & adult with a chest range of 75 – 140 cm & weighing 40kg and above comfortably. It is designed to
be worn over outer clothing and is secured to the body with an adjustable waist belt system which also provides maximum
freedom of movement.
SMA2750 – MODELS, DESIGN & CONSTRUCTION
Models
There are 2 models of SMA2750, namely:-
-Manual Inflation System (SMA2751)
-Automatic Inflation System( SMA2752)
The difference between them is that the SMA 2752 is a manual type with an automatic backup inflation. In other
words, if you opt to use your PFD as a manual, you need to remove the automatic cartridge. With the automatic
cartridge screwed onto the inflator, your PFD will inflate when the cartridge is immersed in water. All other
features are the same for both models.

OM2750.docx
Design & Construction
SMA 2750 is basically made up of a bladder enclosed in a valise. The bladder is made from polyurethane coated
materials .However the valise is made from flame safe fabric called Nomex.
The bladder has the following items on
-60gm co2 gas cylinder inflation mechanism with the pull toggle( Tab);
-Oral inflation tube ;
-Whistle;
-Water activated rescue light which serves as a beacon for an emergency rescue situation ( optional
feature);
-60cm of SOLAS Grade reflective tapes appropriately distributed on the front side of the bladder;
-A collar strap.-
-For SMA2752, automatic cartridge.
The front of the bladder has indelible donning & operating instructions. The back of the bladder contains care
instructions, warning alerts and a service record section.
The valise is not part of the inflation system but acts as a protective covering and as an enclosure for the bladder
when it is deflated by sealing the Velcro fastener which is sewn along the side edges. A small protruding tab at
the bottom right hand side of the valise is used to assist in opening the valise to inspect or service the
bladder inflation system (see fig 1). The valise also houses the adjustable waist belt system but the latter can
be detached from the bladder. Like the bladder, there are donning, operating instructions markings. It also has a
marking to identify whether the PFD is a manual or an automatic model.
The waist belt is made out of durable polyester material and is fastened using a stainless steel buckle and an
adjustable mechanism. Provision is made for excess belt to be tucked away after fastening without any physical
hindrance. The waist belt also has provision for a J knife and a detachable pocket that houses a lifeline.
Both models have a harness sewed onto the valise and is integrated into the waist belt system
RECOMMENDATION:
We strongly recommend that you initially buy 2 re-arming kits for your respective model, one for initial
familiarisation and the other to serve as a spare.
We also recommend that you routinely check your PFD as instructed below. If you are not confident, please send
it to Roaring Forties authorised service agent to attend to your PFD.
TO OPERATE SMA 2750
By jerking the pull toggle of the 60g carbon dioxide gas inflation system, the PFD will inflate. This is for both models. However,
for the automatic model, the PFD will inflate when the automatic cartridge is immersed in water. Hence there is choice for the
automatic model.

OM2750.docx
SOFTENING EFFECT OF THE BLADDER
Acommoncharacteristic of carbon dioxide is that being an unstable gas, it will gradually permeate through
the coated fabric of the bladder of all PFDS over an extended period. Thus a softening effect of the bladder can be observed
over time. For SMA2750, this can be overcome by topping up the pressure of the bladder through the oral tube inflation system.
Another characteristic of carbon dioxide gas is that under colder conditions, it will not expand greatly as in warmer
temperatures. Hence, when experiencing these situations, the bladder pressure needs to be top up using the oral inflation
system. Finally, in the event that the carbon dioxide inflation system fails to inflate the bladder, the oral system should be used
to fully inflate the PFD.

VISUAL INSPECTION CHECKLIST PRIOR USAGE
It is advisable to conduct the following checks periodically after purchasing SMA2750. It must be emphasised
here that your SMA2750 should be properly maintained in order for it to perform effectively in times of need. By
doing so may extend it’s life span.
Figure 3 illustrates how the valise Velcro sides can be separated to expose the inflation mechanism & the bladder.
1 Ascertain whether the gas cylinder has been used.
- For both models, unscrew to remove the gas cylinder from the inflator. Replace gas cylinder
if it is pierced on the head end. (See Fig 3)
2 For both models check whether the green indicator clips are intact --- not missing or broken (See
Figure1 for SMA2751 & Figure 5 & 6 for SMA2752).If missing or broken, replace them.
For the SMA2752, ensure that the green auto firing indicator is not missing. If missing, it may suggest
that
the unit has been fired. Hence, replace the green indicator & the auto cartridge (See Figure 6)
3 Check the physical condition of the bladder fabric and its attachments. Replace the PFD if it is damaged
or has deteriorated.
4 Check for inflation leakage
- Gently uncap the dust cap of the oral tube; If provided
- Inflate the buoyancy bladder by mouth until it is firm and leave it overnight;
- If it is airtight, it should remain inflated and firm the next day;
- If the buoyancy bladder is soft the next day, it indicates a leakage. Replace the PFD or get in
touch with Safety Marine Australia.
5 Deflate the Buoyancy Bladder
- Reverse dust cap, if provided, of the oral tube and insert it into the valve or gently depress the
valve with your fingertip.
- Gently squeeze the inflated bladder until all air or gas has been expelled.
-Ensure Oral inflation valve moves freely and is not stuck down.
- Put back the dust cap back in its stowed position (see fig 4).
6 If everything is intact, ensure that the gas cylinder is screwed onto the inflator hand tight.
7 For both models, ensure the manual pull toggle is in the up and ready position with the green manual
indicator clip is in place. (See figures 1 & 5) For SMA 2752, ensure that the automatic cartridge auto
firing indicator is screwed on to the inflation unit hand tight (see fig 5).
8 Your buoyancy bladder is now ready for repacking into the valise. Please refer to the repacking
instructions section outlined in this manual.
9 Once your PFD is repacked, your Inflatable PFD is ready for use.

Donning Instructions
It is important that your PFD is properly adjusted to fit you. An incorrect fit or improper fastening of the belt or
attachments may impede its performance.
The waist belt fastening system is sewn on and it utilises a quick release buckle for fastening and has an
adjustable mechanism to fit an average person properly.
Figure 7
Put the Inflatable PFD on just like a jacket as depicted by Figure 7 and fasten the front buckle. Adjust the waist belt
using the side release buckle on the belt and secure the belt’s loose end in the belt loop.
This is a constant wear PFD and it is recommended that you are familiar with the donning instructions .It is very
important that you wear your Inflatable PFD over a clothing.
If crotch strops are attached pull these through your legs in a crossover style and attached to the buckles at the
base of the PFD lobes.
CAUTION:
Do not wear your Inflatable PFDs under clothing or harnesses as the inflation could be restricted
and affects its performance and you may also injure yourself
Now that you are happy that everything is in place including familiarisation in donning, it is highly
recommended that you practice using your inflatable PFD & test it in safe shallow water.

OM2750.docx
TESTING YOUR PFD IN WATER
Object of Testing:
-To familiarise yourself with your PFD and to provide you with the first experience of using your PFD
in a water situation so that you will not be overwhelmed should there be a need to use it on another
occasion.
-Also to test whether the PFD will support you on your back or slightly back from the vertical
position with your mouth well above the surface of the water.
-To ascertain whether there is any leakage in the inflation bladder i.e. when you notice any bubbles
appearing.
To test, you need to inflate your PFD and there are basically 2 ways you can inflate if your PFD has a manual
inflation system ( SMA2751) and 3 ways for the Automatic backup inflation system(SMA 2750).
Described below are the three ways to inflate your PFD.
3 Ways to Inflate Your PFD
- Manual inflation
By jerking firmly downward on the pull toggle, the PFD should fully inflate within 5 seconds
- Automatic backup inflation (SMA2752)
Inflation will occur immediately when the inflator is immersed in water. The water sensitive paper element or
bobbin will disintegrate. This will trigger a spring-loaded plunger to puncture the CO2 cylinder head .Thus
allowing the escaping gas to inflate the bladder.
NOTE: Some models can have a sealing cap attached to the automatic system to
prevent inadvertent water activation. Ensure this is removed if wishing water
activation.
- Oral inflation
In the event that the inflation does not occur or in a non-emergency situation, you can fully inflate the PFD by
mouth.
To orally inflate the PFD, remove the dust cap from the top end of the oral tube and gently blow into the tube
until the PFD is firm or fully inflated.
Test using Manual Inflation
- Put on your fully armed PFD and secure it firmly to your body
- Inflate your PFD as described above and it should inflate within 5 seconds.
- Get into shallow water at the depth where you can stand with your head just above the water surface.
- Relax and your PFD will float you in the way it is designed to as described above.
Test using Automatic Inflation
- Put on your fully armed PFD and secure it firmly to your body.
- Likewise get into shallow at the depth where you can stand with your head just above the water
surface.

9
OM2750.docx
- Once the automatic cartridge is immersed in water, your PFD will inflate between 5 to 10 seconds.
- Relax and your PFD will float safely as described above.
Test using Oral Inflation
- Remove the CO2 cylinder & also the automatic cartridge if your PFD is SMA 2752 model.
- Put on your inflatable PFD and ensure that it fits you properly & firmly.
- Get into the shallow water at the depth where you can stand with your head just above the water
surface.
- For non swimmers & weak swimmers, it is advisable that you partially inflate your PFD initially and
gradually move yourself to depth whereby you are well supported enough to be able to complete the
oral inflation without touching the bottom.
- Inflate the PFD fully using the oral tube.
- Relax and allow the PFD to float you to a safe position.
Procedures to follow after Testing
- Remove your inflatable PFD after you get out of the water.
- Deflate your PFD in accordance to the instructions given below.
- Allow your PFD to dry thoroughly in dry but well ventilated area away from direct sunlight.
- Rearm your PFD according to your model.
- Repacked your PFD in accordance to your model’s instructions outlined below.
CAUTION:
Do not co2 inflate your PFD after you have orally inflated it using the oral tube? This is called double
inflation. Your PFD may over pressurise causing damage to it and personal injury.
Deflating the Inflatable PFD
- To deflate the Inflatable PFD, reverse the oral-inflation tube dust cap, if provided, and place it into the
valve or depress valve with fingertip. Since the dust cap will not lock in the deflate position, it is
necessary to hold it in place (Fig. 5).
- Gently squeeze the inflated bladder until all air or gas has been expelled. Do not wring or twist the
Inflatable bladder to avoid damaging it.
-After deflation ensure oral inflation valve moves freely and is not stuck down.
- Put the inflation tube dust cap back in its stowed position on the oral inflation tube (Fig. 5).
- Your device is ready to be re-armed
