3. Risers
4. Lines
15pt JAZZ has 3 risers.
The A riser has a red cover to easy identication.
There is another line with red mailon.
There is A’ and is for the big ears.
They come in different diameters of Kevlar and Dyneema with sheathed cover. They must
to be inspected every 100 hours maximum.
In case of Brake lines, it was cut a little longer, so every pilot can adjust it according to his
personal taste.
But you must always leave 10cm before the brakes line starts acting in order to avoid trailing
edge deformation when the wing is fully accelerated. In case the brake handle comes loose
during ight or any brake lines is cut you can use the C riser softly for directional control
instead of brake line.

5. Adjustable Brake Pulley Position
The brake line pulley position can be adjusted according to pilot preference to suite the
power unit’s hang points height. There are 2 settings: Upper and Lower. The upper setting
(as set by the factory) is for low hang point motors whilst the lower setting is for units with
higher hang points.
If you use the lower pulley, you must lengthen the brake lines accordingly. Moving to the
lower pulleys requires the addition of 5cm to the overall brake line length (measured from
the mark on the brake line).
To change the pulley position, remove the brake line from the pulley by taking off the brake
handle. Re-route the brake line through the other pulley before attaching the brake handle
at the new adjusted length.

15pt 6. Accelerator system
7. Trimmers
The accelerator has being limited in travel up to a safety point, however you can gain 8-12
km of extra speed.
You have to adjust the harness to the speed system so you can use all the speed travel.
To do so you have to be seated in the ground meanwhile you are in your harness and adjust
the lines by pulling up the risers with tension. Another person help to do this is recommend-
ed. Make sure also that the pedal is not pulling down the risers when you are not using it.
Once all the gear is rigged you have to test the whole speed travel in calm air.
The use of the speed system reduces the angle of attack and the canopy may be more sen-
sitive to collapses therefore do not use near the ground or in turbulent air and in case you
are hit by turbulence remove your feet off the pedal bar as quickly as possible.
The JAZZ is supplied with a trim riser set. The ‘neutral’ or standard position is when the
trimmers are pulled all the way down and A/B/C riser lengths are equal. We recommend
performing landing and take-off with the trimmers closed.
The standard trim setting is ideal for climbing under power and when the air is turbulent.
Brake pressure is lighter and the handling at its best in the standard trim setting. To in-
crease cruise speed you can use the speed system, release the trimmers, or do both. Using
the speed system has exactly the same effect as releasing the trimmers so it is safe and
possible to y with the trimmers in the standard position whilst using the full range of the
speed system.
Unlike the majority of reex PPG wings, to increase cruise speed you can use the speed
system, release the trimmers, or do both.
It is not necessary to release the trimmers before accelerating. Using the speed system has
exactly the same effect as releasing the trimmers so it is safe and possible to y with the
trimmers in the neutral position whilst using the full range of the speed system.
In turbulent air the reex prole is very stable. It will resist reasonable levels of turbulence
with a high resistance to collapse without pilot input. The faster the wing is own the more
inherent stability there is, as the reex has a greater effect. In mild turbulence it may be best
to not attempt to y the wing actively and let the prole absorb the turbulence itself, indeed
small applications of the brakes can reduce the inherent stability of the prole. However
in very strong turbulence, we recommends to return the trimmers to the neutral position
(pulled down) and ying the glider actively. This way, you will be in the best position to react
correctly should an incident occur.

15pt 8. Pre-ight check
9. Take-0ff
To know yourself with the glider it is a good idea to perform practice inations and ground
handling with and without the motor.
You should have no difculties ying the JAZZ for the rst time in suitable conditions, but
as with all new equipment.
When you have the new glider, the below points should be inspected.
- Check the lines are clear and not twisted.
- Connection points between the glider and harness.
- All harness buckles are closed.
- The karabiners are fully closed and not damaged.
- The sewing, condition of the lines and connection of the lines are right
- Internal demage to ribs and diagonal ribs.
- Demage to th etop and bottom panels and seams between panels.
Whilst inating the JAZZ, you should hold both of th A risers on your hands. Pilot run in an
upright position and just increases throttle of the engine.
In strong winds it is desirable that an assistant helds the front of the trike from tipping over.
When JAZZ is at an angle of 70 - 80 degrees, pilot should gradually slow it down by brakes.
Once the wing will come to the “normal” angle of attack, while continuing to run, slightly
pull the brakes (20 - 30 cm) to reduce the runway. Don’t stop running until your geet have
left up to the ground and you feel surely safe climb out.
We recommend to take off with closed trimmers.

10.2 Turn control
To familiarize yourself with the JAZZ your rst turns should
be gradual and progressive.
To make efcient and coordinated turns with the JAZZ rst
look in the direction you want to go and check that the air-
space is clear. Your rst 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.
We recommend to take off with closed trimmers.
10. In ight characteristics
10.1 Speed control
JAZZ has ling brake travel length and increased brake pressure.
You can change speed by using the trimmers an speed bar.
By pulling the trimmers to the closed point and brakes are
pulled approximately 30cm, the JAZZ will achieve its best
minimum sink rate.

11.2 Frontal collapse
11.3 Full stall
11.4 Deep stall
JAZZ comes out of symmetrical front collaps by itself. But
It could be fast recovered, if you apply the brake down to
15 to 20cm.
If your wing collapses in accelerated ight, immediately
release the accelerator and manage the collapse using the
same methods described above.
Full stall can occur when you fully pull the both brakes. To
recover to the normal ight you must release both brakes.
After this usually comes a front dive with a possible front
deation. An asymmetric recovery (one control released
faster than the other) from a full-stall can cause a big dy-
namic collapse. The full-stall is a hazardous manoeuvre and
should be only done under the right safety preparations.
It is possible for gliders to enter a state of deep stall. This
can be caused by several situations including; a very slow re-
lease from a B-line stall; ying the glider when wet; or after
a front/symmetric deation.
When you meet this situation you should fully raise up the
both brakes. and push the A-risers forwards or speed bar to
regain normal ight.
11 Deations
11.1 Asymmetric collapse
Turbulence may cause a portion of the wing suddenly to col-
lapse. Asymmetric collapses should be controlled by weight
shifting away from the collapse and applying enough brake
to control your direction. And you should use the brake to
re-inate the glider.

11.6 B stall
11.7 Cravat
The JAZZ has a very clean stable B stall. To enter the B stall,
the pilot has to pull the rst 20cm slowly until the r glider
loses forward speed and starts to descend at around 6 m/s
vertically.. Do not release the brake handles during B stall.
If you pull too much B-line the glider may horseshoe and
move around a lot. If this happens, release the B risers.
To exit the B-stall the B-risers should be released symmetri-
cally and in one smooth, progressive motion. The glider will
resume normal forward ight without further input. Check
you have forward ight again before using the brakes.
In case a cravat should occur from an asymmetric collapse
or other manoeuvres, it is important to keep your ying di-
rection by applying some brake on the opposite side and
weight shift. You can also use strong deep pumps on the
brake to the cravated side, If you can not do it and the rota-
tion is increasing, you must use the parachute.
11 Deations
11.5 Asymmetrical stall
It can take place when you pull one of the brakes too hard,
or while spiraling at a small speed in turbulence you in-
crease the angle of attack. Rotation in the asymmetrical
stall is called negative spiral. This is one of the most dan-
gerous ying situations. In order to get out of asymmetrical
stall, just release the brakes. There may follow side thrust
forward with a following wing collapse.

12.2 Spiral dive
When you hold one sided brake down for a long time, the
glider goes into a fast sharp turn and loses a lot of height.
We recommend you don’t to get into the sink rate
over 10m/s.
The sink rate could be more than 15 m/sec. To get out of the
spiral dive you must release the inner brake. Mind that JAZZ
may take one more turn after releasing the brake. While spi-
ral diving, the pilot experiences considerable overload up to
3 – 4g, so you can lose orientation.
We recommend to land with trimmers to the normal slow position.When you are 1-2m over
the ground, you should pull the brakes smoothly for minimize vertical speed.
Don’t hit the ground by your overtake the glider.
12 Descent Techniques
13. Landing
12.1 Big ears
Sink rate can be decreased in a controlled way by folding
both wing tips. While holding the brakes you should sym-
metrically pull the outermost A-risers
In order to return to the normal ight, you should release
the A-risers and pull the brake short times until wing tips
regain pressure.
Spiraling is not permitted with big ears, because of the in-
creased load on the remaining lines so that they can be
physically deformed.

Cleaning should be carried out with only pure water. If the glider comes in contact with
salt water, clean thoroughly with fresh water. Do not use solvents of any kind, as this may
remove the protective coatings and destroy the fabric.
- Do not expose your glider to the sun any longer than necessary
- Keep it away from water and other liquids
- Do not let the front edge hit the ground
- Keep your glider away from re
- Do not put anything heavy on your glider, do not pack it in a rucksack too tightly.
- Regularly inspect the canopy, lines, risers and harness. If you nd any defects, contact your
dealer or the manufacturer. Do not attempt to repair the paraglider by yourselves.
- If you detect a damaged line, inform the dealer or manufacturer about the line number accord-
ing to the line plan
-Keep your JAZZ in a rucksack in a dry well-ventilated place under neutral temperature and
humidity conditions
-If you do not use the glider, then once a month you should unpack it, ventilate it well, and then
pack it back in the rucksack.
14. Packing your JAZZ
15. Maintenance and cleaning
16. Caring tips
Spread the JAZZ completely out on the ground. Separate the lines to the each side. The
JAZZ must be folded cell to cell to keep the plastic reinforcement at the leading edge lie at
on each other and don’t get bent. Try to pack your JAZZ as loosely as the rucksack allows,
because every fold weakens the fabric.
Avoid packing the glider where it is wet or abrasive conditions(sand, asphalt pavement, con-
crete)

er’s normal performance for two years after the purchase date, but no more than 200 ying
hours. The producer conducts special, and after warranty repairs and maintenance at the
owners’ request for an extra price.
We recommend to inspect your paraglider (including checking suspension line strength,
line geometry, riser geometry and permeability of the canopy material) one time at two
years, or every 150 hours of ying time (whichever comes rst); Those inspection must be
made by manufacturer or dealer.
