WARNING
02
• 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 certied paragliders, harnesses with protector and reserve parachutes that are free
from modication, and use them only within their certied weight ranges. Please remember
that ying a glider outside its certied conguration 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 preight inspection of all of your equipment.
Never attempt ying with unsuitable or damaged equipment.
• Always wear a helmet, gloves and suitable footwear.
• 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 ying.
• Choose the correct wing, harness and conditions for your level of experience.
• Pay special attention to the terrain you will be ying and the weather conditions before
you launch. If you are unsure, do not y and always add a large safety margin to all your
decisions.
• NEVER y your glider in rain, snow, strong wind, turbulent weather conditions or clouds.
• If you use good, safe judgment you will enjoy many years of paragliding.
YOUR ZENO 2
03
The Zeno 2 builds on the success of the original, retaining the same cell count and aspect ratio to maintain
the balance of comfort/performance/ease of use, whilst squeezing more performance, speed, and precision
out of the concept.
Developed alongside the Enzo competition wing project, the Zeno 2 features a completely new prole with
an increased cm+ and more rearward opening positions. This creates an ecient, pitch stable prole that
delivers a higher top speed and better glide performance throughout the speed range.
Performance wise we have seen some impressive gains: with a slightly faster trim speed and signicantly
faster top speed compared to the Zeno, it now matches the Enzo 3 in top speed and glide. Throughout
the normal XC speed range the wing remains comfortable like the Zeno, only becoming slightly more
demanding at the very top speed - but this speed is fast, signicantly faster than the Zeno and only
necessary for competitive nal glides.
Overall, the Zeno 2 oers a little more feedback compared to the Zeno, but always in an intelligible way,
remaining comfortable and condence inspiring for the target group. The heightened sensation makes it
easier to sni out the cores, follow the good energy lines and feel the air intuitively. The optimised internal
structure gives a solid planform with which to climb, in thermic turbulence the wing remains cohesive along
the span and the chord allowing the handling to be exploited whenever necessary. The turn response is
precise and dynamic - rm and precise in the rst part of the range whilst elastic and responsive in the
second.
Passive safety has been improved with less aggressive EN side collapse behaviour and better response
to frontals, the improved behaviour and increased cohesion of the sail is noticeable on the ground, with
impeccable launching characteristics.
Designed and developed for serious, experienced XC pilots who y at least 100hrs a year and have a
good understanding of SIV. The performance makes it perfect for both XC record hunting and top level
competitions.
04
Rucksack
A choice of optional rucksacks are available for your wing. We have a large range suited
for many applications - from large competition bags to accommodate modern competition
harnesses to small lightweight compact designs suited for lightweight harnesses and hike &
y. You can choose from any of them at the time of order, or decide to not take one and re-
use your old rucksack.
Brake Lines
The brake line lengths have been set carefully during testing. We feel it is better to y with a
wrap (one turn of the handle around the hand), for greater turn authority in the thermals and
better overall control. Shortening the brakes from the factory setting will aect the trailing
edge at full speed, so we strongly recommend to not do so. As the wing ages, the brakes will
naturally reduce in length, so it is possible that they will require lengthening at some stage.
When adjusting the brake lengths please keep in mind the following:
• Ensure both main brake lines are of equal length.
• If a brake handle has been removed, check the main brake line is routed through the pulley
when replacing the handle. Use a bowline knot.
• When the brakes are fully released in ight, the brake lines should be slack. There must be
a minimum of around 10cm of free play before the brakes begin to deform the trailing edge
and a substantial bow to guarantee no deformation of the trailing edge when accelerated.
Risers
The Zeno 2 has been designed with 2 risers per side. The A risers have a smaller Dyneema
riser holding the outermost AR3 line. As the wing ages, it is not unusual for the AR3 risers to
reduce in length. Adjustment can be made by releasing the loop found on the small maillon
attached to the B riser. Replacement AR3 risers can also be ordered separately from your
Ozone dealer.
The risers feature a foot operated accelerator system, they do not feature trimmers.
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 (B-risers) for
directional control.
LIMITATIONS
05
Pilot Ability
The Zeno 2 has been designed as a solo high performance XC/competition wing and is suitable
for experienced pilots only. It is NOT suitable for beginner or intermediate pilots, aerobatic
manoeuvres, training or tandem ights. To be own safely, the Zeno 2 requires a high level of
piloting skills, pilots are expected to have the necessary active ying skills and quick reaction
times to keep a high aspect ratio wing open in turbulent air. We also expect an in-depth
knowledge of SIV, preferably with recent, direct experience of a high aspect ratio wing.
Total Weight in flight
Each Ozone glider has been designed and certied for a dened 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:
• For the most precise and dynamic handling or if you generally y in mountains and/or in
strong conditions, you should chose to y near the top part of the weight range.
• If you want a better sink rate, or if you generally y in at lands and/or in weaker
conditions, you may choose to y nearer the middle part of the weight range. Remember,
you can always add ballast when conditions are stronger.
• It is not recommended to y at the very bottom of the weight range.
SIV
As a thoroughbred high performance machine, we do not recommend to use the Zeno 2 for
SIV training. It was certied with the use of collapse lines, therefore induced collapses cannot
be performed correctly, or safely without them. We strongly recommend to not perform
collapses, this is not the wing with which to learn these skills.
If you must use it for SIV it is better to work on your stall control. Ensure you fully understand
the correct and safe use of this equipment before attempting SIV and only do so under expert
tuition over water with all the necessary safety precautions in place.
IMPORTANT
The Zeno 2 was
certied with the
use of collapse lines,
therefore induced
collapses cannot be
performed correctly,
or safely without
them.
06
Towing
The Zeno 2 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 qualied to tow, use a qualied tow
operator with proper, certied 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.
Flying in the Rain
Modern wings are susceptible to rain and moisture, ying with a wet wing can result in the
loss of normal ight.
Due to the ecient, wrinkle-free design of the sail, water tends to bead on the leading
edge causing ow separation. Flow separation will make the wing more prone to entering
inadvertent parachutal stalls, so ying in the rain, or with a wet wing (e.g early morning dew)
should be avoided at all costs.
If you are accidently caught-out in a rain shower, it is best to land immediately. If your wing
becomes wet in the air it is advised to maintain accelerated ight using the speed bar, even
during the nal approach. DO NOT use big ears as a descent technique, big ears increases
drag, and with a wet wing this will further increase the chances of a parachutal stall occurring.
Instead, lose height with gentle 360’s and maintain your air speed at all times. If your wing
enters parachutal stall when wet, immediately accelerate the wing with the speed bar to
regain airspeed.
IMPORTANT
Never y in the rain or
with a wet glider.
PREPARATION
07
IMPORTANT
Using the accelerator
decreases the angle
of attack and makes
the wing more prone
to collapse, therefore
using the accelerator
near the ground or in
turbulent conditions
should be avoided.
Accelerator System
Attach the speed system lines to the accelerator system on the risers with the Brummel
hooks. Alternatively they can be bypassed with the speed system attached directly to the riser
accelerator lines using a Larks foot.
There must be enough slack in the speed system to ensure the A risers are not inadvertently
pulled during normal trim speed ight, but not so long that it is impossible to use the full
speed range of the glider.
Maximum speed is achieved when the A/B limiter comes under tension. Pushing the speed
system beyond this point will not increase the speed.
Once set up, test the full range of the accelerator in calm ying conditions and ensure that
both risers are pulled evenly during operation. Fine-tuning can be completed when you are
back on the ground.
Harness
It is important to set up your harness correctly before ying the wing. Make sure to spend time
adjusting your harness’s dierent settings until you are completely comfortable. Depending
on the size of the wing, we recommend a chest strap setting between 42cm and 48cm
(measured between the centre of the hang points). The S size was certied with a chest strap
set to around 42cm, the MS/ML between 44-46cm, and the L between 46-48cm. Do not y
with a chest strap setting too tight (below 42cm) or too wide (above 48cm) as this will aect
the behaviour and feedback of the wing.
The wing has been certied with a standard seated harness. Using a pod harness in a laid
back supine position does not invalidate the certication but it may have an inuence on
the behaviour of the wing. Pod harnesses increase the risk of twists occurring during a large
asymmetric collapse.
08
Wing
To prepare the wing, lay it out on the top surface and perform a thorough daily check. You
should inspect the top and bottom surfaces for any rips and tears or any other obvious signs
of damage. 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 B and A lines, including the upper C’s laying the
checked lines on top of the previous set. Make sure no lines are tangled, knotted or snagged.
Mirror the process on the other side and then inspect the lines for any visual damage.
Inspect the risers for any signs of obvious damage or wear. Ensure they are not twisted, pay
particular attention to the Dyneema AR3 risers as these are easily twisted.
Take-o checklist:
1. Check reserve parachute - pin is in and handle secure
2. Helmet on and fastened
3. All harness buckles closed - check leg-loops again
4. Risers connected to the harness correctly with carabiners and maillons tight
5. Accelerator system connected
6. Holding the A risers and your brake handles correctly
7. Leading edge open
8. Aligned in the middle of the wing and directly into wind
9. Airspace and visibility clear
