T
hank you for choosing to fly Ozone.
As a team of free flying enthusiasts, competitors and adventurers, Ozone’s mission is to build agile paragliders of the highest quality with cutting edge designs and performance and maximum security.
Confidence and belief in your paraglider is a far greater asset than any small gains in performance - ask any of the Ozone pilots on your local hills, or
those who have taken our gliders on ground-breaking adventures and stood on podiums around the world. All our research and development is concentrated on creating the best handling/performance characteristics possible with optimum security. Our development team is based in the south of
France. This area, which includes the sites of Gourdon, Monaco and Col de Bleyne, guarantees us more than 300 flyable days per year. This is a great
asset in the development of the Ozone range.
As pilots we fully understand just how big an investment a new paraglider is. We know that quality and value for money are essential considerations
when choosing your new paraglider; so to keep costs low and quality high we build all our wings in our own production plant. During production our
wings undergo numerous and rigorous quality control checks. This way we can guarantee that all our paragliders meet the same high standards that
we expect ourselves.
This manual will help you get the most out of your LM5. It details information about the LM5’s design, tips and advice on how best to use it and how to
care for it to ensure it has a long life and retains a high resale value. If you need any further information about Ozone, the LM5, or any of our products
please check www.flyozone.com or contact your local dealer, school or any of us here at Ozone.
It is essential that you read this manual before flying your LM5 for the first time.
Safe Flying!

Paragliding is a potentially dangerous sport that can cause serious
injury including bodily harm, paralysis and death. Flying an Ozone paraglider is undertaken with the full knowledge that paragliding involves
such risks.
As the owner of an Ozone paraglider you take exclusive responsibility
for all risks associated with its use. Inappropriate use and or abuse
of your equipment will increase these risks.
Any liability claims resulting from use of this product towards the
manufacturer, distributor or dealers are excluded.
Be prepared to practice as much as you can - especially ground handling, as this is a critical aspect of paragliding. Poor control while on
the ground is one of the most common causes of accidents.
Be ready to continue your learning by attending advanced courses to
follow the evolution of our sport, as techniques and materials keep
improving.
Use only certified paragliders, harnesses with protector and reserve
parachutes that are free from modification, and use them only within
their certified weight ranges. Please remember that flying a glider
outside its certified configuration may jeopardise any insurance (e.g.
liability, life etc) you have. It is your responsibility as the pilot to verify
your insurance cover.
Make sure you complete a thorough daily and pre-flight inspection of
all of your equipment. Never attempt flying with unsuitable or damaged equipment.
Always wear a helmet, gloves and boots.
All pilots should have the appropriate level of license for their respective country and third party insurance.
Make sure that you are physically and mentally healthy before flying.
Choose the correct wing, harness and conditions for your level of
experience.
Pay special attention to the terrain you will be flying and the weather
conditions before you launch. If you are unsure do not fly, and always
add a large safety margin to all your decisions.
Avoid flying your glider in rain, snow, strong wind, and turbulent
weather conditions or clouds.
If you use good, safe judgment you will enjoy many years of paragliding.
Remember, PLEASURE is the reason for our sport
Everyone at Ozone continues to be driven by our
passion for flying, our love of adventure and our
quest to see Ozone’s paraglider development create
better, safer and more versatile paragliders.
Paragliding design is led by the ever thoughtful David Dagault; Dav
has a wealth of experience both in competition, adventure flying and
paraglider design. Also on the design team are Russell Ogden, Luc
Armant and Fred Pieri.
Russ is a top competition pilot and ex paragliding instructor, he can
usually be found putting Dav’s latest creation through a series of
test manoeuvres.
Luc, a dedicated XC addict has a background in naval architecture.
He brings a wealth of knowledge and ideas to the design team and
works closely with Dav in the design process.
Fred is the latest addition to the team. He is a mathematian,

prototypes as well as researching materials and manufacturing processes for our future products. He is backed up by Khanh and 700
production staff.
YOUR LM5

ENGLISH
Rucksack
The bag is light in weight, comfortable and useful (padded hip belt,
ergonomic and adjustable shoulder straps). It has a large volume that
will allow you to store all your kit, whilst still being comfortable for
hiking.
Brake Lines
The brake line lengths have been set carefully during testing. We feel
it is better to have slightly long brake lines and to fly with a wrap
(one turn of line around the hand). However, if you do choose to adjust them, please bear in mind the following:
Ensure both main brake lines are of equal length.•
If a brake handle has been removed, check that its line is still •
routed through the pulley when it is replaced.
When the brake handles are released in flight, the brake lines •
should be slack. There must be a substantial “bow” in them to
guarantee no deformation of the trailing edge.
There must be a minimum of 10cm of free play before the brakes •
begin to deform the trailing edge. This prevents the trailing edge
from being deformed when using the speed system.
IMPORTANT: In the unlikely event of a brake line snapping
in ight, or a handle becoming detached, the glider can be
own by gently pulling the rear risers (C-risers) for directional control.
Risers
There are 2 different riser options available for the LM5; Standard
and Lightweight. Standard risers are made from 12mm black Cousin
webbing and the lightweight risers are made from 7mm Dyneema.
Both have specially designed ‘Link Lite’ connectors to hold the riser
lines. Link Lites are tested to over 500kg and save weight compared
to standard maillons.
Note: At trim speed the risers are NOT of equal length.
See page 53
The LM5 was developed specifically for the X-Alps race. It combines
cutting edge design technology recently gained from the Ozone Performance Project and the Mantra R series of wings (R11, R12, EnZo)
and over a decade of ultra-light paraglider construction and material
research.
An aspect ratio of 6.9 offers a balance of performance and manageability, and a highly refined internal tension lends a tight and compact
feel across the span of the wing, even in turbulent conditions. This
coordinated feel, combined with an ideal aspect ratio, translates to
superb climbing characteristics and high efficiency during turbulent
glides.
The LM5 profile is a hybrid design combining the best features of the
SharkNose Technology with the fun and efficiency of the Delta 2. It
is solid at accelerated speeds, and extremely resistant to spin and
stall. The shark profile provides a more constant internal pressure in
active air and turbulence, increasing passive stability and creating an
even more comfortable and stable feel in accelerated flight. The new
profile has also improved the launch behaviour by reducing “shooting”
in higher wind conditions.
Precise feedback is provided by the LM5’s 3-line system. The 3 line
design provides the optimum balance between ease of takeoff, usability in active air, overall weight / size, and comfort / performance.
Weight has been reduced to a minimum without compromising the
strength and safety of the wing. The LM5 has full EN D flight and
load test certification. With a tight, crisp, agile feel in the air and
performance that rivals competition wings, the LM5 is built to carry
you through the most demanding of flyable conditions.
The LM5 is suitable for highly experienced and competent XC pilots
who spend more than 100 hours per year in thermal conditions.
BASIC FLIGHT TECHNIQUES
6
Accelerator System
To set up an accelerator on the ground, ask a friend to pull your
risers into their in-flight position while you sit in your harness. Now
adjust the length of the line so that the main bar sits just beneath
your seat. You should now be able to hook your heel in to the secondary (lower) loop of the accelerator.
The accelerator must be slack enough to ensure that the front risers
are not pulled down in normal flight, but not so long that it is impossible to use the full speed range of the glider.
Extending the secondary (lower) loop of the accelerator fully will take
the glider through approximately half its accelerated speed range.
Should you need even more speed you should hook your feet on to the
upper bar, which you can then extend until the pulleys on the risers
touch.
Once set up, test the full range of the accelerator in calm flying conditions: ensure that both risers are pulled evenly during operation.
Fine-tuning can be completed when you are back on the ground.
IMPORTANT: Using the accelerator decreases the angle
of attack and can make the glider more prone to collapse,
therefore using the accelerator near the ground or in turbulence should be avoided.
Harness
It will be in your harness that you will enjoy flying. Therefore, we
recommend you spend the time necessary to adjust your harness’s
different settings until you are completely comfortable. This will make
flying more pleasurable.
The shoulder straps and the hip straps need to be set for comfort
(make sure you do not have your shoulder’s strap too tight, or you
might find it difficult to get seated after launching). The ideal position
in your harness should be with your knees horizontal and your body
position leaning slightly backwards with your head behind the risers.
The chest strap should be set between 42cm and 46cm (between
the centre of the hang points). S, MS and ML sizes are certified with
a chest strap set between 44cm and 46cm.
Total Weight in flight
Each Ozone glider has been certified for a defined weight range. We
strongly recommend that you respect these weight ranges. If you
are between sizes the following information may help you make a decision as to which size to buy:
If you want better speed, precise handling or if you generally fly in
mountains and/or in strong conditions, you should chose to fly in the
top part of the weight range. If you want a better sink rate, or if you
generally fly in flat lands and/or in weak conditions, you may choose
to fly near the bottom part of the weight range. Remember, you can
always add ballast for when conditions are stronger.
To familiarise yourself with the glider it is a good idea to perform
practice inflations and small flights on a training hill. This will enable
you to set up your equipment correctly. If in any doubt please get
advice and help from your local dealer or instructor.
Preparation
Lay out the wing on its top surface in a pronounced arc, with the
centre of the wing higher than the tips. Lay out the lines one side
at a time. Hold up the risers and starting with the brake lines, pull
all lines clear. Repeat with the stabilo, C, B and A lines, laying the
checked lines on top of the previous set, and making sure no lines are
tangled, knotted or snagged. Mirror the process on the other side.
Take-off checklist:
1. Check reserve parachute - pin in and handle secure
2. Helmet on and fastened
3. All harness buckles closed - check leg-loops again
4. Karabiners and maillons tight

ENGLISH
5. Holding the A’s and your brake handles
6. Leading edge open
7. Aligned directly into wind
8. Airspace and visibility clear
Launching
Your LM5 will launch with either the forward or reverse techniques.
Forward Launch - Nil to Light winds
When the wind is favourable, whilst gently holding the A risers move
forward positively, your lines should become tight within one or two
steps and the LM5 will immediately start to inflate. You should maintain a constant pressure on the risers until the wing is overhead. Do
not pull down or push the risers forward excessively, or the leading
edge will deform and possibly collapse making taking-off more difficult
and potentially dangerous.
Move smoothly throughout the entire launch, there is no need to
rush or snatch at it. You should have plenty of time to look up and
check your canopy before committing yourself. Once you are happy
that the LM5 is inflated correctly, accelerate smoothly off the
launch.
Reverse Launch - Light to Strong Winds
Lay out your wing as you would for the forward launch. However, this
time turn to face it, passing one entire set of risers over your head
as you turn. Now you can inflate the glider with the A-risers. Once
the wing is overhead, release the risers, brake gently if necessary,
turn and launch.
In stronger winds, be prepared to take a few steps towards the
glider as it inflates. This will take some of the energy out of the glider
and it will be less likely to overfly you. This reverse-launch technique
can be used in surprisingly light winds too.
IMPORTANT: Never take off with a glider that is not fully
inated or if you are not in control of the pitch/roll of your
wing.
Practice ground handling a lot! Not only is it great fun, but it will give
you a much better feel for your wing’s flight characteristics. It will
also improve your overall enjoyment of flying by giving you the feeling
of control and making your launches easier and less stressful.
Landing
The LM5 shows no unusual landing characteristics but as a reminder,
here are some tips:
Always set up for your landing early, give yourself plenty of op-•
tions and a safe margin for error.
Once below 30 metres avoid turning tightly. •
Allow the glider to fly at hands up (trim) speed for your final de-•
scent until you are around 1 metre above the ground (in windy or
turbulent conditions you must fly the glider actively all the way).
Apply the brakes slowly and progressively to slow the glider down
until groundspeed has been reduced to a minimum and you are
able to step onto the ground.
In light winds/zero wind you need a strong, long and progres-•
sive flare to bleed off all your excess ground speed. In strong
winds your forward speed is already low so you are flaring only
to soften the landing. A strong flare may result in the glider
climbing upwards and backwards quickly, leaving you in a vulnerable position.
If the glider does begin to climb, ease off the brakes (10-20cm) •
- do not put your hands up all the way - then flare again, but
more gently this time. Keep the brakes at mid speed, stand up,
be ready to run and make sure you brake fully as you arrive on
the ground.
In strong winds you need to turn towards the glider the second •
your feet touch the ground. Once facing the wing pull smoothly
and symmetrically down on the brakes to stall the wing. If the
glider pulls you, run toward it.
If the wind is very strong, and you feel you might be dragged, or •
lifted again, stall the glider with the C risers. This stalls the wing
in a very quick and controllable way and will drag you less than if
you use the brakes.
Always land heading into wind!•
8
Active Flying
To minimize the likelihood of suffering collapses in turbulent conditions, it is essential to use active flying.
Flying with a small amount of brake applied (approx. 20cm) will give
you feedback from the wing. In turbulent conditions the internal pressure of the wing can change and you will feel this through the brakes.
The aim is to maintain a constant pressure through the brakes. If
you feel a loss in pressure apply the brakes until normal pressure
is resumed then raise hands back to original position (this must be
done quickly). Avoid flying with continuous amounts of deep brake in
rough air as you could inadvertently stall the wing. Always consider
your airspeed.
These movements can be symmetric or asymmetric; you may have to
apply both brakes or just one. These subtle adjustments will keep the
glider flying smoothly and directly above you and dramatically reduce
the chances of a collapse. If the glider pitches in front of you, use the
brakes to slow it down. Equally, if the glider drops behind you, release
the brakes to allow it to speed up. The goal is to always keep the
wing directly overhead.
These are skills that are best learnt by playing with the glider on the
ground!
IMPORTANT: No pilot and no glider are immune to collapses
however active ying will virtually eliminate any tendency
to collapse. When the conditions are turbulent, be more active and anticipate the movements of your wing. Always be
aware of your altitude and do not over-react. We strongly
advice you to always keep hold of your brakes. Do not y in
turbulent conditions.
In Flight Characteristics
The LM5 shows no unusual flying characteristics, turns are smooth
and co-ordinated, it remains solid and well pressured on glide, even
through the accelerated speed range. It has a very high resistance
to both collapses and stalls. However, it is a high performance XC
wing and is therefore only suitable for experienced pilots who fly approximately 100hrs a year and who have SIV experience.
Normal Flight
Flying at ‘trim speed’ (hands-up), the LM5 will achieve its ‘best glide’
speed for still air. You should fly at this speed when gliding downwind
or when the air is not excessively sinking.
For better penetration in headwinds and improved glide performance
in sinking air, crosswinds or headwinds, you should fly faster than
trim speed by using the accelerator system. Using up to half bar
does not degrade the glide angle or stability significantly and will improve your flying performance. You will reach the next thermal faster
and higher. At full speed the LM5 is stable; however we recommend
that you do not fly at full speed close to the ground or in turbulence.
By applying the brakes approximately 20cm, the LM5 will achieve its
minimum-sink rate; this is the speed for best climb and is the speed
to use for thermalling and ridge soaring.
Turning
To familiarize yourself with the LM5 your first turns should be gradual
and progressive.
To make efficient and coordinated turns with the LM5 your first input
for directional change should be weight-shift, followed by the smooth
application of the brake until the desired bank angle is achieved. To
regulate the speed and radius of the turn, coordinate your weight
shift and use the outer brake.
IMPORTANT: Never initiate a turn at minimum speed (i.e.
with full brakes on) as you could risk entering a spin.
IMPORTANT: Always check for clear airspace before making
a turn!

ENGLISH
RAPID DESCENT TECHNIQUES
Ozone would like to remind you that these manoeuvres should be
learnt under the supervision of a qualified instructor and always used
with caution. Never forget that properly analysing the conditions
before launch will help avoid the need to use these techniques.
Big Ears
Folding in the wingtips increases the wing’s sink rate. This is useful
for staying out of cloud or descending quickly. To pull big ears, keep
hold of your brake handles and take the outermost A-line on each
side, then pull down (preferably one at a time) until the tips of the
wing fold under. The Outer A line is attached to the Baby A riser,
making identification and use of the big ear system easier.
Do not use the brakes other than for re-inflation. For directional control while using the Big Ears, you should use weight shift.
To reopen your big ears, release both A lines at the same time. To
help reinflation, brake gently one side at a time until tips regain pressure. Avoid deep symmetric applications of the brake as this could
induce parachutal or full stalls.
IMPORTANT: You can land with the ears (you should release
the ears before nal are). Ozone do not advise you to do
this when it’s turbulent or windy due to the risk of a possible stall and lack of precision in steering.
Big ears and accelerator
Once the big ears are in you can further increase the sink rate by
pushing on the accelerator bar.
NEVER try to pull the Big Ears in with the speed bar on. This
can lead to a major asymmetric deation. Always make the
Big Ears rst and then apply the speed bar.
Active C Riser Control
When gliding at trim or in accelerated flight it is possible to pilot the
wing with the C risers. This gives an improved feel and control over
the wing enabling you to fly actively without using the brakes (which
causes drag and pitch movements). The direct feel allows you to stop
collapses before they happen and maintain higher speeds and higher
levels of efficiency through turbulence.
To fly with the C risers, keep hold of your brake handles (remove
any wraps) and take hold of the handles located at the top of the C
risers. With the C risers you can fly actively through turbulence; If
you feel the nose of the wing lose internal pressure you can apply
pressure to the C’s to keep the nose open. The amount of pressure
and size of the input is dependent on the amount of turbulence, but
always be gentle at first to learn the feel of the wing and to avoid
large pitch movements.
NOTE: This control method is suitable for gliding in good
‘normal’ air without huge turbulence, it does not replace
proper active ying with the brakes in strong turbulent
conditions. If you are unsure about the air return the glider
to trim speed, release the C risers and y the glider actively
with the brakes.
IMPORTANT: Be careful to use only small inputs to the risers as you risk stalling part or all of the wing if you are over
enthusiastic. Be prepared for plenty of practice as this new
method may take some time for it to become totally intuitive, efcient and comfortable.
10
Spiral Dives
If you turn your glider in a series of tightening 360’s it will enter a
spiral dive. This will result in rapid height loss. To initiate a spiral,
look and lean in to the direction you want to go, then smoothly pull
down on the inside brake. The LM5 will first turn almost 360 degrees
before it drops into the spiral. Once in the spiral you should re-centre
your weightshift and apply a little outside brake to keep the outer
wing tip pressured and inflated.
Safe descent rates of 8m/s (1600 ft/min approx.) are possible in
a spiral dive, but at these rates the associated high speeds and
G-forces can be disorientating, so pay particular attention to your
altitude.
To exit the spiral dive, ensure your weight shift is not engaged, use
opposite weight shift if necessary and then release the inside brake.
As the LM5 decelerates allow it to continue to turn until enough energy is lost for it to return to level flight without an excessive climb
and surge.
In normal conditions the LM5 shows no tendency to remain locked in
a spiral dive; however some parameters may interfere with its behaviour. These include: wrong settings of the chest strap, total weight
in flight outside of the certified weight range, or being in a very deep
spiral at a very high sink rate. You should always be prepared to pilot
the wing out of such a spiral dive. To do so, smoothly use opposite
weight shift and apply a small amount of outside brake and the glider
will start to resume normal flight. Never attempt to recover from a
spiral with hard or quick opposite inputs as this will result in an aggressive climb and surge.
IMPORTANT: Always be prepared to pilot yourself out of a
spiral dive using opposite input if necessary.
IMPORTANT: Spiral dives with sink rates over 8 m/s are
possible, but should be avoided. They are dangerous and
put unnecessary strain on the glider. Spiral dives cause
disorientation and need time and height to recover. Do not
perform this manoeuvre near the ground.
Big ears and spiral dive
Whilst it is possible to enter a spiral dive whilst holding in Big Ears,
the high forces applied to the lower lines could exceed the breaking
strain of the lines leading to equipment failure!
Ozone strongly recommend to NOT use this manoeuvre!
Wingovers
The limit is tightly banked S-turns, commonly known as wingovers.
These must not exceed 90 degrees of bank.
WARNING: Uncoordinated wingovers can lead to large
asymmetric collapses and cravats, therefore they should
never be executed near the ground.
B-Line Stall
B-stall is for fast descents in emergency situations only. B-stall is
performed by symmetrically pulling down on both B-risers.
If you pull too much B-line the glider may horseshoe and become
unstable.
To exit the B-stall the B-risers should be released symmetrically and
in one smooth, progressive motion. The glider will resume normal forward flight without further input. Check you have forward flight again
before using the brakes.
IMPORTANT: We do not recommend the use of B line stalls
with the LM5. Pulling too much B line and or turbulence can
cause the tips to y forward and become unstable. Spiral
dive is a safer way to loose height effectively.
11
ENGLISH
INCIDENTS
Deflations
Due to the flexible form of a paraglider, turbulence may cause a portion of the wing suddenly to collapse. This can be anything from a
small 30% (asymmetric) collapse to a complete (symmetric) collapse.
If you have a collapse, the first thing to do is to control your direction. You should fly away from the ground or obstacles and other
pilots, or at least not to fly into them... Asymmetric collapses can
be controlled by weight shifting away from the collapse and applying a
small amount of brake to control your direction. This act will most of
the time be enough for a full recovery of the wing.
Once a glider is deflated it is effectively a smaller wing, so the wing
loading and stall speed are higher. This means the glider will spin or
stall with less brake input than normal. In your efforts to stop the
glider turning towards the collapsed side of the wing you must be
very careful not to stall the side of the wing that is still flying. If you
are unable to stop the glider turning without exceeding the stall point
then allow the glider to turn whilst you reinflate the collapse.
If you do have a deflation, which does not spontaneously reinflate,
make a long smooth progressive pump on the deflated side. This
pumping action should take about 2 seconds per pump. Pumping too
short and fast will not reinflate the wing and pumping too slow might
take the glider close to, or beyond, the stall point.
Symmetrical collapses reinflate without pilot input, however 15 to
20cm of brake applied symmetrically will speed the process.
If your LM5 collapses in accelerated flight, immediately release the
accelerator to slow down to trim speed and after approximately a 90
deg turn the canopy will reinflate and return to normal flight.
Cravats
If the tip of your wing gets stuck in the lines, this is called a ‘cravat’.
This can make your glider go into a spiral, which is difficult to control.
The first solution to get out of this situation is to stabilise the glider
into normal flight, i.e get control of your direction and then pull down
the stabilo line (green line on the C riser) until the wing tip frees
itself. You must be careful with any brake inputs or you may stall the
opposite wing. If this does not work, a full stall (symmetrical or asymmetrical) is the only other option. This should not be done unless
you have been taught how to do it and can only be done with a large
amount of altitude. Remember if the rotation is accelerating and
you are unable to control it, you should use your reserve parachute
whilst you still have enough altitude.
IMPORTANT: A bad preparation on launch, aerobatic ying,
ying a wing of too high a level or in conditions too strong
for your ability, are the main causes of cravats.
Deep Stall / Parachutal stall
It is possible for gliders to enter a state of parachutal stall. This can
be caused by several situations including; a very slow release from
a B-line stall; flying the glider when wet; or after a front/symmetric
deflation. The glider often looks as though it has recovered properly
but carries on descending vertically without full forward motion. This
situation is called ‘deep stall’ or ‘parachutal stall’.
Should it happen, your first reaction should be to fully raise both
brakes, this action alone normally allows the glider to return to normal flight. If nothing happens after a few seconds, reach up and push
the A-risers forwards or apply the speed bar to regain normal flight.
Ensure the glider has returned to normal flight (check your airspeed)
before you use the brakes again.
IMPORTANT: Only a few cms of input from your brakes can
maintain your wing in the stall. Always release your wraps
if you have taken them!
IMPORTANT: Never y in rain or with a wet wing, this will
signicantly increase the likelihood of parachutal stall. If
you are accidently caught-out in a rain shower, land immediately. DO NOT use big ears as a descent technique; big
12
ears with a wet wing will further increase the chances of a
parachutal stall occurring. Instead, lose height with gentle
360’s and make sure to consider your air speed during nal
approach, use a small amount of speed bar if necessary.
ACROBATIC / SIV FLYING
The LM5 has been designed as a high performance XC wing and is not
intended for aerobatic manoeuvres.
It is possible to perform SIV with this glider. Simulated TRIM speed
asymmetric and symmetric collapses are possible but due to the
nature of the tab positioning, induced FULL speed ASYMMETRIC and
SYMMETRIC collapses are not recommended. To do so properly, and
to be in line with certification requires the addition of collapse lines
to the leading edge which have to be mounted accurately, All other
manoeuvres are possible and are permitted with the normal precautions.
IMPORTANT: Ozone strongly advises against performing induced full speed Asymmetric and Symmetric collapses with
this wing.
TOWING
The LM5 may be tow-launched. It is the pilot’s responsibility to
use suitable harness attachments and release mechanisms and to
ensure that they are correctly trained on the equipment and system
employed. All tow pilots should be qualified to tow, use a qualified tow
operator with proper, certified equipment, and make sure all towing
regulations are observed.
When towing you must be certain that the paraglider is completely
over your head before you start. In each case the maximum tow force
needs to correspond to the body weight of the pilot.
Step 1 Lay mushroomed wing on the
ground or the Saucisse pack. It is best to
start from the mushroomed position as
this reduces the dragging of the leading
edge across the ground.
Step 2 Group Leading Edge (LE) plastic reinforcements with the A
tabs roughly aligned,
make sure the plastic
reinforcements lay side
by side.
Step 3 Strap LE...Note the glider is
NOT folded in half; it is folded with a
complete concertina from tip to tip.
It is really important to not stress
the middle cell or bend the plastic too
tightly.
CARING FOR YOUR WING
Packing
To prolong the life of your wing and to keep the plastic reinforcements
in the best possible condition it is very important to pack the wing
carefully.
Ozone strongly recommends to use the concertina packing method
exactly as shown so that all of the cells rest alongside each other
and the plastic reinforcements are not unnecessarily bent. Using the
Ozone Saucisse pack will help preserve the life of the wing and aid
with the speed and ease of packing.
13
ENGLISH
Step 4 Group together the middle/
trailing edge of the wing by sorting
the folds near the B, C and D tabs.
If using a Saucisse pack go to Step 8
Step 5 Once the LE and rear of the
wing have been sorted, turn the
whole wing on its side.
Step 6 Fold the wing with 3 or 4
folds whilst being careful to not
crush the LE
Step 7 Nowplace the folded wing into the stuff
sack.
Step 8. If using the Saucisse Pack
carefully do it up without trapping any
material.
Step 9. Turn the Saucisse on its side
and make the first fold just after the LE
reinforcements. Do not fold the plastic
reinforcements, use 3 or 4 folds around
the LE.
IMPORTANT: Do NOT lay the wing at on the ground before
packing the glider, this will cause abrasion damage to the top
surface as you pull the glider towards the middle. ALWAYS pack
from a mushroom or lift the wing off the ground when gathering
the wing and grouping the leading edge.
Important: Do not fold the glider in the centre, you will
bend the plastics, instead pack the wing with a full concertina method from tip to tip before packing into the stuff sac.
14
humidity are particularly bad for your glider (Storing a damp glider in
your car under the sun would be terrible for example). Dry your wing
preferably out of the sun, in the wind. Never use a hair dryer, etc.
If you land in the salt water, you must clean it with fresh water first
and then dry it.
Take care that no insects get packed away with the wing. They may
eat the cloth and make holes in a bid to escape. They can also leave
acidic deposits if they die and decompose.
IMPORTANT: Never pack away or store your glider wet.
Cleaning
Any kind of wiping/scratching can damage the coating of the cloth.
We recommend for cleaning to use a soft cloth dampened only with
water and to use gentle movements little by little across the surface.
IMPORTANT: Never use detergent or chemical cleaners.
Wing Repairs
Amateur repairs often do more harm than good. Always let a registered dealer, professional repair centre or the manufacturer carry
out ant major repairs.
If you damage the sail:
If the rip is small, you can fix it yourself. You’ll find all the materials you need in the repair kit, a tear can be simply mended with the
sticky rip stop/spinnaker tape. When cutting out the patch remember
to allow ample overlap around the tear and round the corners of the
patch. You can find more information about repairing your wing on the
Ozone website, including step by step instructions with pictures.
If you damage a line:
Any line that is damaged should be replaced. It is important that
the replacement line is from the same material, has got the same
strength and the same length. You can check its length against its
Caring Tips
Careless ground handling damages many paragliders. Here are some
things to avoid in order to prolong the life of your aircraft:
DO NOT drag your wing along the ground to another take-off •
position - this damages the sailcloth. Lift it up and carry it.
DO NOT try to open your wing in strong winds without untan-•
gling the lines first - this puts unnecessary strain on the lines.
DO NOT walk on the wing or lines.•
DO NOT repeatedly inflate the glider and then allow it to crash •
back down. Try to keep this movement as smooth as possible by
moving towards the glider as it comes down.
DO NOT slam your glider down on the ground leading edge first! •
This impact puts great strain on the wing and stitching and can
even explode cells.
FLYING in salty air, in areas with abrasive surfaces (sand, rocks •
etc.) and ground handling in strong winds will accelerate the aging process.
Your Ozone wing has an opening closed using velcro on the trail-•
ing edge of the tip called the ‘butt hole’. This has been designed
to easily empty all the things which have been accumulating in
your wing (sand, leaves, rocks, mobile phones etc).
If you fly with a wrap, you should regularly undo the twisting that •
appears on the main brake lines. By twisting the line become
shorter and you can end up with a constant tension on the trailing edge (which can lead to problem on launch, stalling, glider not
flying symmetrically, ...)
Change your main brake lines if they are damaged.•
It is recommended that you regularly CHECK your wing, especially
after a heavy period of use, after an incident or after a long period of
storage.
Storage
Always store all your flying equipment in a dry room, protected from
the direct heat.
Your wing should be dry before being packed away. Moisture, heat and

time in seconds is the result. A measurement is done in a several
places on the top surface along the span of the glider behind the
leading edge.
The tearing resistance of the cloth - A non-destructive test following
the TS-108 standard which specifies minimum tear strength for sky
diving canopies should be made using a Bettsometer. (B.M.A.A. Approved Patent No. GB 2270768 Clive Betts Sails)
Strength of the lines - An upper, middle and lower A line, along with a
lower B and a lower C (and lower D if applicable) line should be tested
for strength. Each line is tested to breaking point and the value recorded. The minimum value is 8 G for all lower A+B lines and 6 G for
all lower remaining lines, calculated from the maximum certified flying
weight of the glider. The added minimum strength for the middle lines
and for the top lines should be the same.
If the breaking strength is too close to the minimum value calculated,
the professional should give a period after which you will have to test
the strength of the lines again.
Lengths of the lines - The overall length (riser lines + mid lines +
upper lines) has to be checked under 5Kgs of tension. The difference
between the measured length and the original length should not
exceed +/- 10mm.
The changes that could appear are a slight shrink on the C or Ds and/
or a slight stretch on the A, B. The consequences of these changes
can include a slower trim speed, difficult inflation etc.
Full check - A full visual check should be carried out: All the components of the wing (stitching, ribs, diagonals, lines, tabs, ...) should be
checked for signs of deterioration.
Finally, a flight test that confirms that the wing behaves normally
should be carried out by the professional.
IMPORTANT: Take care of your glider and make sure you
counterpart on the other side of the wing, to make sure that it is
symmetrical. Once the line has been replaced, inflate and check the
glider before flying. If you do not have access to an Ozone dealer you
can order individual lines at www.flyozone.com
MAINTENANCE CHECKS
Your wing, like a car, should be technically checked to ensure proper
airworthiness.
Your wing should be checked by a qualified professional for the first
time after 24 months, or after 100 hours. However, if you are a
frequent flyer (more than 80 hrs per year), then we recommend, that
you get your glider checked annually.
The checker should inform you about the condition of your glider and
if some parts will need to be checked or changed before the next
normal service check period.
The sail and the lines do not age in the same way or at the same
rate; it is possible that you may have to change part or all of the
lines during the wing’s life. For this reason it is important to do
regular inspections so that you know the exact condition of all of the
components of your glider. We recommend that inspections are carried out by a qualified professional.
You alone are responsible for your flying kit and your safety depends
on it. Take care of your equipment and have it regularly inspected.
Changes in inflation/groundhandling/flying behaviour indicates the gliders aging, if you notice any changes you should have the wing checked
before flying again.
These are the basic elements of the check up (full details and permissible figures can be found on our website):
Porosity is measured with a porosity meter, the time taken by a
certain volume of air to go through a certain surface of the cloth. The
16
have it checked according to the above schedule: This will
ensure you hours of safe ying.
MODIFICATIONS
Your Ozone LM5 was designed and trimmed to give the optimum balance of performance, handling and safety. Any modification means the
glider loses its certification and will also probably be more difficult
to fly. For these reasons, we strongly recommend that you do not
modify your glider in any way.

SUMMARY
Safety is paramount in our sport. To be safe, we must be trained,
practised and alert to the dangers around us. To achieve this we
must fly as regularly as we can, ground handle as much as possible
and take a continuous interest in the weather. If you are lacking in
any of those areas you will be exposing yourself to more danger than
is necessary.
Every year many pilots get hurt launching; don’t be one of them.
Launching is the time that you are most exposed to danger so practice it lots. Some launch sites are small and difficult and conditions
aren’t always perfect. If you’re good at ground handling you’ll be able
to confidently and safely launch whilst others struggle...practice as
much as you can. You’ll be less likely to get hurt and more likely to
have a great day’s flying.
Finally, RESPECT the weather, it has more power than you can ever
imagine. Understand what conditions are right for your level of flying
and stay within that window.
Happy flying & enjoy your LM5.
