any of us here at OZONE.
We are confident your glider will satisfy your flying needs for a long time. This
booklet gives advice on keeping it safe and in the sort of condition which will give
you the best resale value if you ever want to change. You can help this by logging
all your flights and maintenance.
Please ensure that this manual is passed on to the new owner if you do resell the
glider.

THE OZONE PEOPLE
OZONE PEDIGREE
John and Rob have each won two World Championships and twice been
awarded the Gold Medal of the Royal Aero Club. OZONE is proud that they have
brought such experience to this young company.
Rob Whittall: Testing, teaching, competing and winning: Rob has flown on most
flyable days for the last 14 years. His passion for free flying burns as strong as
ever. Rob is a complex personality whose flying style can be extreme, yet he is
driven by the development of safety in paragliding. It is not a paradox: who
understands the limits better than someone who is capable of pushing a wing far
beyond them?
David Pilkington: Doctor of aerodynamics and computer star. David has
developed OZONE'S ultra-advanced design software that slices the time from
drawing board to sky. Relaxation? Fortunately for us he just loves playing with
gliders.
John Pendry: The legend in foot-launched flight. His 25 years of experience and
outstanding competition record make him the most respected pilot ever. John's
cool style is the perfect counterpoint to Rob's passion and they both agree
perfectly on OZONE'S philosophy that safety and fun are what paragliding is all
about.
Mike Cavanagh: Mike has plenty of international paragliding experience as
British Team Manager and a keen competitor too. It's OZONE'S good fortune that
he is a fully trained accountant who can keep a close eye on the numbers and
what they mean to the customers. Mike's managerial skills and easygoing
character make him popular with pilots and dealers alike.
David Dagault: Current French Champion, famous for his massive alpine cross
country flights and long time French team member, David is the newest member
of the Ozone design team. David is involved in research and helping Rob with test
flying. Only 24 years old, he has all of 12 years’ flying experience - that means he
has been flying paragliders as long as Rob. David brings new skills, new ideas
and a decidedly French accent to team Ozone.

The best part about starting a new company is that you get the opportunity to
choose the ideal materials. We have put together what we think is the best
possible combination for durability, performance and longevity.
We started to develop our first wing on a clean sheet of paper. The choice of
materials was one of the first problems to solve. In the end we chose the material
that we knew would do its particular job best. End of story. Here's what OZONE
gliders are made of:
Upper-surface
Gelvenor silicone-coated sailcloth from South Africa. High tenacity 100%
polyamide, weight 49g/m2. We consider that this has the best resistance to
ageing of any sailcloth currently on the market.
Lower-surface
Porcher-Marine sailcloth from France. High tenacity Skytex+ Ripstop Nylon
45g/m2 SO finish. This tried-and-tested cloth gives the best strength-for-weight
ratio going, combined with good durability.
Ribs
Porcher-Marine again. High tenacity Skytex+ Ripstop Nylon 45g/m2 FM finish.
This has been selected for stability and resistance to stretch - vital if a glider is to
keep its safe-flying characteristics for a long time.
Leading-edge reinforcement
Double-laminated Mylar. Selected for long-term durability, this ensures that your
glider's take-off characteristics will remain consistently good for season after
season.
Lines
Edelrid has long been one of the market leaders in the manufacture of
suspension line. We chose their High Modulus Aramid for its stretch resistance,
high thermal tolerance and acknowledged durability. The lower lines are strength
and age tested by the DHV. The supple sheath helps prevent lines tangling and
kinking, which is important for longevity.
Line specifications: 80/120/160/200 kg breaking strength.
Risers and hardware
Riser webbing - 20/25mm zero-stretch polyester webbing.
Shackles - High quality Delta maillons from Maillon Rapide.
Pulleys - AustriAlpin aluminium mini pulleys with brass roller.
All these components have been chosen for their renowned quality and durability.

CHECKING AND MAINTENANCE
PRE-FLIGHT CHECK
It is very important that you perform regular maintenance checks on your glider
especially before and after long flights, flying trips and long periods of storage.
To avoid forgetting points it is helpful to always use the same procedure:
1. Inspect all sewing on the harness, rescue bridle and risers.
2. Check all quick links, maillons and karabiners.
3. Check brake handle knot. Follow brake lines up to the wing, checking for knots
and damage.
4. Check all other lines up to the wing.
5. Inspect all line attachment points to the wing.
6. Inspect upper and lower surface for damage and ageing.
7. Interior inspection: inspect ribs for damage or fatigue.
If you find any signs of damage or abnormal wear, consult your dealer, school or
OZONE for advice.
Your glider will have undergone thorough checks at every stage of manufacture
and have been signed-off by skilled inspectors. But don't believe us! Do a pre-
flight check for your first flight and then at least at the start of every flying day.

The brake lines connect to the trailing edge via a series of subsidiary lines.
Because of their positions they are more easily scuffed than other lines on your
glider, so they should be checked extra frequently.
The main brake lines run through pulleys connected to the rear risers. The brake
handles are tied to the main lines and conveniently positioned press-studs attach
them to the risers when not in use. This should prevent them twisting and
tangling.
Adjusting brake lines
Important: the lengths of the brake lines will have been set carefully during testing
and manufacture. At OZONE 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, we know that
some pilots prefer the lines slightly shorter and may wish to adjust them.
Whatever you choose, make the following checks:
· Ensure both main brake lines are of equal length.
· If a brake handle has been removed for any reason, 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 should be a substantial "bow" in them and absolutely no deformation of the
trailing edge.
We recommend a minimum of 10cm of free play between the brake release
position and the start of deformation on the glider. This will prevent the trailing
edge from being deformed when using the speed system.
In the unlikely event of a brake line snapping in flight, or a handle becoming
detached, the glider can be flown by gently pulling the rear risers (D-risers) for
directional control.
