CUMEO

36 Description Technical Data 37

2 DESCRIPTION

The CUMEO is our lightweight interpretation of the CHILI concept. Our glider for perfor­mance-driven XC pilots, who prefer to set their turning points off the beaten path, is so
light that you won’t need a cable car when your big day comes. The lightweight materials
of Porcher Marine are applied to reduce weight only in areas not felt by the XC pilot.
That is why the CUMEO is just as solid in the air as its »heav y« brother and has the same
balanced characteristics. You’ll feel the difference - in the backpack on the way to launch
or in the baggage net of the train on the long way back from your epic flight.

PILOT REQUIREMENTS

The CUMEO’s high level of performance and its forgiving handling make it suitable for am­bitious thermal flyers and XC pilots, as well as for those moving up a class who already have
experience with lower level gliders. The CUMEO is not suitable for novices nor for those who
fly infrequently.

SCOPE OF DELIVERY

The CUMEO comes standard with inner bag, compression strap, glider backpack,
riser bag and manual.

CAUTION

THE FIRST FLIGHT MUST BE CARRIED OUT BY A QUALIFIED EXPERT.

THE TYPE CERTIFICATE AND THE DATE OF THE FACTORY INSPECTION
CAN BE FOUND IN THE MIDDLE CELL OF THE GLIDER.
THE DATE OF THE FIRST FLIGHT AND NAME OF THE PILOT SHOULD
BE ENTERED HERE. SHOULD THIS BE MISSING, ASSUME THAT THIS GLIDER
IS A PROTOTYPE THAT HAS NOT BEEN TESTED.

JET FL APS

Each of our gliders is equipped with skywalk’s patented JET FLAP technology. Air is
conducted from the bottom of the wing (pressure area) to the top of the wing (vacuum
area) and is blown out there with a higher speed. The connection is established through
jet shaped channels located toward the back of the wing. The addition air mass on the
top of the wing delays the flow separation. The stall occurs later, the minimum flyable
speed is lower, and the pilot has more reserve in the angle of attack. This is especially
important in phases such as takeoff and landing. The JET FL APS also help to improve
climb performance since they allow you to circle very slowly in thermals with little danger.
The glider can be flown normally as the JET FLAPS don’t require any special control
technique.

EN

CUMEO

The skywalk CUMEO may not be flown:

> outside of the minimum and maximum certified takeoff weights
> with a motor
> in rain, snow, or in extremely turbulent weather conditions, or in strong wind
> in clouds or fog (visual flight)
> with insufficient pilot experience
> if flown with more than one person
> if the canopy is wet
> at temperatures under -30°C or over 50°C
> for acrobatic flight (flight maneuvers at an angle of more than 135 degrees)

During production, the CUMEO underwent carefully selected quality controls and was
inspected once again before shipping. Keep in mind that a paraglider can only be flown
while observing the laws of the country in which it is flown.

2 LINE SYSTEM

The layout of the suspension points is designed for optimal load distribution and a long
lifespan. With all considerations and calculations however, our focus is always on safety.
The mix of materials used on the lines of the CUMEO is an ideal combination of durability,
low stretch and low drag.

The skywalk CUMEO has 3 A-, 3 B-, 3 C-, and 1 stabilo line.
The main-stabilo is connected with the B-riser.
The brake lines are not load-bearing and lead from the trailing edge over the main brake
lines through the brake pulleys on the C-risers to the brake handles.

A marking on the main brake line indicates the position of the handle attachment.
This setting should not be lengthened, for example, to provide more brake travel in extreme
flight situations or during landing, nor shortened such that the glider is flown constantly
with some brake on.

To provide a better overview and to make sorting easier,
the lines have different colors:

> the AI, AII mainlines and the A-riser are red. The AIII mainline has a red cover at the loop.
> the BI, BII mainlines are yellow. The BIII mainline has a yellow cover at the loop.
> the CI, CII mainlines are blue. The CIII mainline has a blue cover at the loop.
> the stabilo mainlines have a green cover at the loop
> the main brake-lines are orange
The lines are attached with loops to triangular shackles and secured with plastic inserts.

The skywalk CUMEO has 4 risers per side:
> the two inner A-mainlines lead to the inner A-riser, the outer A-line leads to the outer A-riser
> the B-lines as well as the stabilo lines lead to the B-riser
> the C-lines lead to the C-riser
A schematic drawing of the risers can be found at the back of the manual.

IMPORTANT S

AFETY WARNING

FLYING A PARAGLIDER REQUIRES MA XIMUM CAUTION AT ALL TIMES.
WE REMIND YOU THAT YOU FLY YOUR PARAGLIDER AT YOUR OWN RISK!
AS THE PILOT IT IS YOUR RESPONSIBILITY TO ENSURE THE AIRWORTHINESS
OF YOUR GLIDER BEFORE EVERY FLIGHT. REMEMBER THAT MENTAL FITNESS
IS AL SO A RISK FACTOR.

CUMEO

LAYING OUT THE GLIDER

If you use your paraglider for the first time we recommend that you practise some
inflations and try some simple flights at a training site. This way you are able to get
used to your skywalk CUMEO. Lay out the canopy so that the leading edge is slightly
arched. The middle of the canopy should form the deepest point of the paraglider.
This way the A-lines are tensioned first in the middle whilst inflating.
The paraglider inflates evenly which ensures a stable and straight take off.

The CUMEO is very easy to sort due to the 3 line levels, yet sorting should always
be completed carefully. All lines have to run freely without any knots and twists
from the risers to the canopy.

During flight, tied or crossed over lines can often not be released or untangled!
The brake-lines are lying directly on the ground, so please pay attention that they do
not become entangled during launch. There shouldn’t be any lines beneath the canopy
during take-off. Line-overs can have fatal consequences!

TAKE-OFF

The skywalk CUMEO is easy to launch.
Hold the A-risers and the brake handles in your hands. For a better identification,
the covers at the A-risers are coloured red. The brake lines are coloured
orange and the brake handles are black. Hold your arms slightly sideways and backwards
like an extension of the A-risers. Before launching check the laid out glider.

Further check the wind direction and the airspace! Pull rapidly and the canopy of
the skywalk CUMEO will launch and rise above your head. The canopy will inflate fast
and reliably. Keep the paraglider straight above your head and run for ward.
Slow down a little as soon as the upward pull decreases.You can open any collapsed cells
by pumping the affected side. Changes of directions that are necessary can be carried
out now. Look and feel that the wing is properly inflated.
Don’t make your final decision to accelerate or to take-off until you are absolutely sure
that the wing is properly and evenly inflated.

Otherwise, stop the take-off procedure immediately! During reverse launches
and in strong winds, it is possible that the paraglider surges forward and inflates
faster than intended.
You can counteract this by running towards the glider. We recommend practicing
this demanding launch technique on a flat slope! If you reverse launch it is advisable
to only use the inside A-risers. This way the glider opens a bit more slowly and
in strong winds you don´t have to deal with the full pressure at once.

3 ACCELERATION SYSTEM

The skywalk CUMEO can be equipped with a foot-operated acceleration system.
The acceleration system effects the A, A2 and B-risers. Exact lengths and an illustration
of the risers can be found at the end of the instructions.
Both risers are equipped WITHOUT trimmers.

4 HARNESS

The skywalk CUMEO is licensed for all certified harnesses of the GH type
(harnesses without solid cross-bracing).
Be aware that the relative brake travel and the agility of the glider change with
the height of the attachment point.

5 FLIGHT TECHNIQUES AND CHARACTERISTICS

PREFLIGHT CHECK AND MAINTENANCE

It is important to check all paragliding equipment thoroughly before every flight to see
if it has any defects. Also check the paraglider after long flights and after long storage.

Check thorougly:

> All seams on the harness, the rescue chute attachments and the risers
> That all connecting parts, line shackles and carabiners are closed
> The brake line knots right and left, following the lines all the way up to the canopy
> All other lines from the risers to the canopy
> All line attachment points on the canopy
> The top and bottom of the wing for damage and wear and tear
> The profiles and the crossports on the inside
> If the glider is dry

CAUTION

DO NOT LAUNCH IF YOU FIND ANY DEFECTS, EVEN SMALL ONES!
IF YOU FIND ANY SIGNS OF DAMAGE OR ABNORMAL WEAR AND TEAR,
CONTACT YOUR FLIGHT SCHOOL OR SKYWALK DIRECTLY.

Flight Techniques and Characteristics 41

CUMEO

Examples:

> To avoid large changes in the angle of attack, release the brakes when flying into strong
updrafts and pull them when flying into downdrafts.
> When flying in turbulent air, if you feel a drop in pressure in parts of your glider, pull
the brake briefly and progressively until the pressure becomes normal again.
If you brake the wing too quickly and too far, you risk stalling it!

ACCELERATED FLYING

The speed bar should be secured to the harness prior to launch.
To use the acceleration-system you will need to make some effort. This can affect the
sitting position in the harness. Therefore we recommend an upright position in the har­ness. Adjust the harness before your first attempt of accelerated flight.
We remind you to only fly in wind conditions that don’t require constant use of the
acceleration-system.
To reach the maximum speed press the acceleration-system firmly until both pulleys on
the A-risers touch each other. As soon as you apply the acceleration-system the angle of
attack will be reduced, the speed increases, but the paraglider becomes less stable and
can collapse more easily. Therefore always use the acceleration-system with adequate al­titude from the ground, obstacles and other aircraft.

Avoid adjusting the speed bar too short. It is impor tant to avoid unintentionally accelerat­ing the glider due to a setting that is too short. Accelerated collapses are normally more
impulsive and demand fast reactions.

CAUTION

NEVER ACCELERATE IN TURBULENT AIR!
NEVER ACCELERATE NEAR THE GROUND!
NEVER LET GO THE BRAKE HANDLES!
NEVER BRAKE THE GLIDER SYMETRICALLY WHILE FLYING ACCELERATED!

LANDING

The skywalk CUMEO can be landed easily. Make your final approach against the wind and
let the glider slow down at its own rate. Further reduce the speed by applying the brakes
lightly and evenly. At about 3m above the ground you increase the angle of attack by slow­ing down more and eventually completely flare out the glider.
When you have reached the minimal speed apply full brake. In strong head winds, slow
down carefully. When you have reached the ground safely, stall the glider warily.
Avoid turning sharply before your final approach. This increases the danger of pendu­lum effect!

TURNING

The skywalk CUMEO is ver y manoeuvrable and reacts to steering inputs directly and with­out delay. Simple weight shift enables you to fly very flat turns with minimal altitude loss.
Combined steering technique: Weight shifting and pulling of the inside brake line allow ex­tra tight turns. During turning you can control the speed, the curve radius and banking by
additional use of the outer brake. Counter braking or releasing the brake lines can change
these parameters most effectively.

CAUTION

PULLING THE BRAKE LINES TOO FAR AND TOO FAST CAN CAUSE A STALL!
YOU CAN RECOGNIZE AN IMPENDING NEGATIVE SPIN BY THE HIGH CONTROL
LINE PRESSURE AND SLIGHT BACKWARDS FOLDING OF THE WING TIP.
IF THIS HAPPENS, RELEASE THE INSIDE BRAKE IMMEDIATELY.

EMERGENCY STEERING

Should a brake line break or a brake handle become detached, you can still steer and land
the glider with limited control using the C-risers.

AC T IVE FLYI NG

Active flying means flying in harmony with your paraglider. That means that instead of
flying with the brakes always in the same position, you are aware of the slightest distur­bances in the air and react accordingly, especially in turbulent thermals.
Never let go of the brake handles, especially in turbulent conditions!

Despite your glider’s high stability, you should constantly use brakes and weight shif to
correct the position of the canopy in turbulence. With a light tug on the brakes you can
constantly keep in contact with the canopy and feel its internal pressure. That way you
can recognize and react early to a pressure drop and impending collapse. Accelerated col­lapses in general tend to be more impulsive and require increased attention on the par t
of the pilot. As you gain experience, these reactions will become instinctive.

The skywalk CUMEO rarely collapses even without a pilot reaction. However, maintaining
an active flying style will greatly increase your margin of safety.

PACKING

Conscientiously packing your glider guarantees a consistently high quality.
First, remove all leaves, grass, sand, etc., then sort the lines and lay them on top of the
glider. Always make sure that the glider is dry and clean before you pack it.

Start with the second cell from the middle and lay them cell for cell on top of each other
so that the reinforcements of the inlets are kept together. Repeat this process on the
trailing edge by starting from the middle and folding together every second panel, drawing
them towards the middle. After that, lay the folded panels on top of each other and press
the air from the trailing to the leading edge. After doing this on both sides, turn one half
onto the other and beginning from the bottom, fold the glider up towards the leading edge.
You can fold the risers in with the glider or leave them sticking out at the bottom or still
attached to your harness. When packing, remember to straighten out the lines and shack­les to keep them from bending. After every fold, let out the remaining air in the glider
through the leading edge. Attach the compression strap around the glider loosely and
place it in the nylon bag. If you prefer to use a tube, the steps are the same up the point
where you turn the folded panels onto each other. Pull the straps tight and make sure that
no material is caught in the zippers.
You can also pack any skywalk glider with elastic nylon wires by any other method without
damaging the leading edge. Place the harness with the seat board facing up (to distribute
the load better) on top of your glider and close the zippers.
You will find adequate space rest of your equipment (helmet, overall, instruments, etc.)
under the cover of the rucksack.

A hint to increase the life of your glider even more:
Don’t pack your glider too tightly. Treat the leading edge with care despite its robustness
and open up your wing a bit if you store it for a longer period of time.

WINCHTOWING

The skywalk CUMEO is well suited for winch towing. Make sure that you only use certified
winches and that you climb from the ground at a flat angle.
The pilot must have had proper towing instruction and must ensure that the winch opera­tor has had proper training that includes paragliders. When launching on a winch, always
fly with a lot of feeling and don’t brake too much as your glider will already have an in­creased angle of attack. We recommend the use of a towing adapter.

FLYING WITH A MOTOR

Currently, the CUMEO has no certification for flying with a motor.
You can find out the current status of motor certification at any dealer or importer, or by
asking sky walk directly.

6 DESCENT TECHNIQUES

This manual is not intended to be an instruction manual and sky walk highly recommends
taking part in a safety training course over water.
The following hints will help you to get the most out of your glider.

For all extreme maneuvers it is important:

> First to practice them under the tutelage of a certified flight instructor as part
of a safety training course.
> To ensure that the airspace below you is clear before entering each maneuver.
> To maintain eye contact with your glider throughout each maneuver.

SPIRAL DIVE

The skywalk CUMEO does not tend to enter a stable spiral dive – rather, it will recover
by itself if the brakes are released. You can enter a spiral dive by carefully increasing the
brake pressure on the inside of a turn while shifting your weight in the same direction.
If the glider doesn’t bank enough and the sink rate doesn’t increase, it’s better to start
over again rather than to keep applying brake without sensitivity. The spiral begins when
the glider banks sharply to the side and enters a sharp, steep turn. You can control the
bank angle and descent rate by applying or releasing the inside brake.

The spiral dive can be used to lose altitude quickly, so please
consider the following:

> High sink rates and the related high G-forces lead to a high physical strain on the body
that may be too much for inexperienced pilots! Approach spiral dives slowly!
> Tensing your stomach muscles during a spiral dive can be very helpful!
> If you feel dizzy or faint, exit the spiral dive immediately!
> Due to the extreme altitude loss in a spiral dive, make sure you always have
enough safe reserve.
> To avoid strong surging when exiting the spiral dive, release the inside brake slowly
while continuing to apply the out side brake.
> The brake line pressure in a spiral dive is substantially higher than in normal flight!

Descent Techniques 45

44 Flight Techniques and Characteristics

CUMEO

B-LINE STALL

The B-lines are pulled down symmetrically 15-20cm. Keep the brake handles in the
respective hands. The airflow on top of the profile largely detaches and the paraglider
descends without flying for ward. Pulling hard on the B-risers allows you to decrease the
area of the wing and increase your sink rate, but this also increases the risk of the wing
forming a rosette to the front. If this happens, recovery from the B-stall immediately!
You can exit the stall by quick and symmetric release of the B-lines. The paraglider will
pitch forward and pick up speed. At no time you may use the brakes in this case!
If the wing doesn’t reopen you may speed up the opening process by gently braking.
Subsequently: Since the CUMEO has only 3 levels, the amount of energy needed for the
B-stall is higher than with conventional 4 level paragliders.
Generally speaking, the B-stall is a maneuver that is being performed less and less, since
it subjects the glider materials to a lot of stress.

7 EXTREME FLIGHT MANEUVERS

ASYMMETRIC COLLAPSE

Your skywalk CUMEO is a very stable glider, but collapses can still happen in strong
turbulence. The inherent turn toward the collapsed side of the glider can be minimized
by braking the open side. With large collapses, brake the open side carefully to avoid stall­ing the wing.
If the collapse doesn’t open despite braking and weight shifting on the open side, you can
speed up the opening process by repeatedly pumping the brake on the collapsed side.

CR AVAT/ L IN E OV ER

This type of disturbance has never occurred during test flights with the sky walk CUMEO.
However, it is possible in extremely turbulent air or due to a pilot error that part of the
wing could get tangled in the lines. The pilot should first stabilize the glider by carefully
braking the open side. Without pilot reaction, a cravat can cause a glider to enter a stable
spiral dive!

To clear the cravat, there are several possibilities:

> Pumping the open side
> Pulling on the stabilo-line
> Perform a manual collapse of the affected side
> Fullstall

Should these maneuvers not succeed or if the pilot fells overwhelmed by the
situation, the rescue parachute should be deployed immediately!

CAUT ION

TO EXIT A SPIRAL WITH A HIGH SINK RATE (> 14M/S), IT MAY BE NECESSARY
TO BRA KE THE OUTSIDE HALF OF THE GLIDER A ND/OR TO SHIFT YOUR
WEIGHT TO THE OUTSIDE OF THE TURN. THE EXIT MAY REQUIRE SEVERAL
COMPLETE ROTATIONS AND MAY CAUSE A HIGH LOSS OF ALTITUDE.
FOR THIS REASON, DON’T PERFORM THIS MANEUVER AT AN ALTITUDE OF
LESS THAN 200 METERS! BY THE TIME YOU REACH THIS ALTITUDE,
THE MANEUVER SHOULD HAVE ALREADY BEEN COMPLETED!

BIG EAR S

In contrast to the spiral dive, with big ears your forward speed is higher than your sink speed.
This descent method is used to quickly leave dangerous areas in a desired horizontal direc­tion. To collapse the wing tips, pull down both out side A-lines, which are connected to sepa­rate A-risers. The resulting collapsed wing tips will put the glider in a stable sink flight.
The brake handles remain in your hands together with the outer A-risers. The glider can still
be steered by braking on one side or by weight shif ting. The danger of canopy disturbances
in turbulent air is greatly reduced with big ears. To increase your sink rate as well as your for­ward speed, you can also optimize this maneuver with the help of the speed bar.

To exit, release the A-lines. The canopy will normally reopen by itself. You can brake
a little to speed-up the opening. It is better if you reopen one side at a time to reduce
the danger of a stall.

Examples:

> If the pilot is surprised near a summit with little ground clearance by strong wind
or a thundercloud, neither a B-stall nor a spiral dive can help.
> If the pilot is stuck in ver y strong lift, it is advisable to exit the lift band with the use
of big ears and to find sinking air in which to lose altitude.

CUMEO

NEGATIVE SPIN

A paraglider enters a negative spin when one side of the wing is stalled. The canopy
rotates around the ver tical axis with the center of rotation located within the wingspan.
The inside wing flies backwards.

There are two causes for the negative spin:

> One brake is pulled too far and too hard (e.g. when entering a spiral dive)
> One brake is pulled too hard when flying slowly (e.g. while thermal flying).
If an accidental negative spin is exited immediately, the skywalk CUMEO will normally
resume flight without much altitude loss. Just release the brake line that was pulled too
far until the airflow is restored to the inside wing. After a long negative spin, the canopy
may surge forward on one side. This could result in an impulsive collapse.

WINGOVERS

Alternating left and right turns as the bank angle is gradually increased. If wingover
are flown high with a large bank angle, the outside wing tip may loose pressure and
start to feel light. In this case, don’t increase the bank angle any more as the tip could
collapse impulsively.

CAUTION

CAUTION

NEGATIVE SPINS AND WINGOVERS OVER 135° ARE FORBIDDEN ACROBATIC

MANEUVERS AND ARE NOT ALLOWED TO BE FLOWN UNDER NORMAL
CONDITIONS.THE WRONG EXIT TECHNIQUE OR PILOT OVERREACTION CAN
HAVE DANGEROUS CONSEQUENCES REGARDLESS OF THE TYPE OF GLIDER!

FULLSTALL

A glider enters a full stall when both brakes are pulled down too far. The glider loses for­ward speed and eventually collapses back behind the pilot.

CAUTION

AT THIS MOMENT IT IS IMPORTANT TO NOT LET UP ON THE BRAKES,
OTHERWISE THERE IS THE DANGER THAT THE GLIDER MAY SURGE FORWARD
IN FRONT OF THE PILOT AND MAY EVEN FALL BELOW THE PILOT.

The available brake line travel depends on the glider size and is about 59cm for size XX S,
62 cm for size X S, 65cm for size S and 68cm for size M..
However, these values are only reference points to give an idea of the useable brake
travel. In turbulent air, a stall can occur much earlier or later with the application of a
higher or lower amount of brake line travel.

FRONTSTALL

The glider can be front-stalled with a strong pull on the A-risers or when encountering
sudden down drafts. The leading edge collapses impulsively along its entire length.
Light brake pressure can reduce oscillations around the longitudinal axis and will help to
speed up the opening of the canopy.
The skywalk CUMEO will recover from a front stall by itself. Should the recovery be delayed
by turbulence, you can support it with light braking on both sides. Make sure that you don’t
over brake your glider!

PAR ACHUTA L S TALL

The CUMEO never showed a tendency to parachutal stall in the entire development
phase. Despite this, it is possible to perform a parachutal stall. Gliders with porous
material (UV radiation) are especially susceptible, as are those that are burdened
frequently by winch tow launches. A parachutal stall can also occur when the glider is
flown in rain (soaks up moisture). The glider has no forward speed and a high sink rate.

The skywalk CUMEO will normally recover from a parachutal stall by itself. If this doesn’t
happen, the pilot can end the stable parachutal stall by pushing forward on the A-risers at
the level of the line shackles or by activating the speed bar with your feet.

CAUTION

IF YOU APPLY THE BRAKES DURING A PARACHUTAL STALL, THE GLIDER
WILL IMMEDIATELY ENTER A FULL STALL. NEAR THE GROUND, A STABLE
PARACHUTAL STALL SHOULD NOT BE EXITED DUE TO THE RESULTING
OSCILLATIONS. INSTEAD, THE PILOT SHOULD SIT UP IN HIS HARNESS
AND PREPARE FOR A PARACHUTE LANDING FALL.

9 MAINTENANCE

With proper care, your skywalk glider should remain air worthy for many years.
A well treated glider will be able to fly twice as many hours as a glider that after each
use is stuffed without feeling back into its sack.

Always remember: your life depends on your glider!

STORAGE

Ideal is a dry, dark place with a constant temperature. Moisture is an old enemy of the
durability of all paragliders. For this reason, always dr y your equipment before you store it,
preferably in a heated and well ventilated room, so that moisture can evaporate.

CLEANING

Any rubbing or abrasion can cause your glider to deteriorate quickly. The PU coated canopy
material is dirt-repellent and in emergencies, can be cleaned easily. If you still think you
need to clean your glider (e.g. of cow manure), then use a soft, damp towel or a sponge
WITHOUT soap, solvent or detergent. Let your glider dry thoroughly before storing it.

REPAIR

Repairs should only be carried out by the manufacturer or by an authorized skywalk
service center. Exceptions include the repair of small cuts (up to about 5 cm that don’t
affect a seam) that can be patched with skywalk sail tape, and the swapping out of lines.
Replacement lines can be ordered directly from the sky walk homepage.

LINE REPAIRS

The main lines of the sk ywalk CUMEO consist of a Dyneema- or Technora core. Avoid
heavy loads on individual lines as excessive stretching may be irreversible. Repeating
kinking of lines at the same spot reduces their strength. Visible damage to lines, even
if it’s only to the sheath, should be checked and possibly repaired.
New lines can be ordered from the manufacturer or from an authorized skywalk ser vice
center. They will help you to replace defective lines. Before a line is replaced, the correct
length has to be verified by comparing it with the corresponding line on the other side
of the wing. After the replacement and before your next flight, perform a line check by
kiting up the glider on the ground.

TRIM CHECK

To ensure maximum safety and performance, we recommend to measure the lines of
the glider after 50 flight hours or 200 flights (according to which occurs first) to check

the trim of the glider.

8 MATERIALS

The skywalk CUMEO is manufactured from the highest quality materials.

the highest quality control. Should your glider someday no longer be flyable, remove all
metal parts such as shackles, pulleys, etc.
All remaining parts such as lines, material and risers can be turned in at a recycling
center. The metallic parts can be turned in at a metals recycling center. The best solution
is to send your retired skywalk glider directly to us. We will then take care of recycling it.

11 MAINTENANCE CHECK

According to LTF regulations your glider will have to undergo a maintenance check after
24 months or after 150 flight hours (according to which occurs first).
According to these regulations the Two-Year-Check has to be carried out by the manu­facturer, its representative or by the owner himself. The check will have to be confirmed
by a official stamp (ex. Checkair label). Missing this deadline or if the check is carried out
by an unauthorised company will lead the skywalk CUMEO to lose any guarantee claim.
We recommend not doing this check yourself. Without the proper instruments and specific
knowledge the check will be insufficient. Airwor thiness is therefore not guaranteed.

CAUTION

IF THE GLIDER IS SUBJECTED TO ABOVE AVERAGE WEAR AND TEAR
(EXTREME FLIGHT MANEUVERS, FORBIDDEN ACROBAT FLIGHT MANEUVERS)
OR IS USED FREQUENTLY IN SAND OR SALTY AIR, IT SHOULD BE INSPECTED
EARLIER OR SHOULD UNDERGO AN ADDITIONAL INSPECTION!

Changes to the paraglider:

Your skywalk CUMEO is manufactured within the regulated parameters of tolerance.
These parameters are very narrow and must not be altered under any circumstance.
Only this way the optimum balance between performance, handling and safety can be
guaranteed!

CAUTION

UNAUTHORIZED CHANGES INVALIDATE THE TYPE APPROVAL AND ALL
LIABILITY CLAIMS AGAINST THE MANUFACTURER ARE INVALIDATED.

HINTS FOR MATERIAL C ARE

> Avoid leaving your glider unused in the sun or lying outside in bad weather.
> Avoid exposing your glider to abrasion by dragging it over sticks and stones.
> Always fold your glider carefully and loosely and avoid sharp creases and extreme
compression of the material.
> Always store the risers in the riser bag provided.
> Should the material come in contact with salt water, rinse it immediately and carefully
with fresh water and make sure that it has enough time to dry in a shady location.
> If you land in a tree, never pull hard on the lines or material to free your glider. Rather,
do so carefully and with patience. Once you have removed all leaves and branches from
your glider, inspect the line lengths and symmetr y before your next flight.
> When laying out your glider, make sure that neither material nor lines are dirty as
particles caught in the fibers can shorten the lines and damage the material.
> If lines get caught on the ground, they can get stretched or torn during launching
For this reason, make sure that all lines are free and avoid stepping on them
> Make sure that no snow, sand or stones find their way into the canopy because weight
on the trailing edge of the glider can brake or even stall it. Should this happen anyway,
lift up the glider by C-lines so that the air inlets are pointing down and the canopy
can empty itself.
> When launching in a strong wind, part of the glider may hit the ground hard. This can
lead to tears in the ribs or damage to the seams. For this reason, inspect your glider on
a regular basis for this type of damage.
> After landing, don’t let the glider fall to the ground on its nose as this can damage
the material in the leading edge.

CUMEO

12 HOMOLOGATION

The CUMEO is certified to LTF 09 and EN926-1, EN926-2 in the category B.
The CUMEO is defined as a lightweight sport aircraft with an empty weight of less
than 120kg in the paraglider category. The many homologation tests are the last hurdle
in the development of a skywalk paraglider. The homologation test flights only take place
when the test team is completely happy with the glider development.
We remark that the certification results will differ during flight in thermals or turbulent air.
The homologation informs solely regarding the paraglider performance during extreme­flight-manoeuvres performed in stable air conditions. These extreme-flight-manoeuvres
during the homologation process should thus not be over-valued.
Remember that certification maneuvers were carried out with a harness in the group GH
with a carabiner distance (middle to middle) of 42-46 cm. If another harness is used, the
glider may display flight characteristics that differ from those in the description.

13 NATURE AND ENVIRONMENTALLY COMPATIBLE BEHAVIOR

We have taken the first step towards ecological awareness with our nature-friendly
sport . Especially with our mountain climbers who prefer to climb to the launch site.
Nevertheless, we plan on continuing in the same vein. This means specifically: clean up
your trash, stay on marked trails and don’t cause unnecessar y noise. Please help to
maintain the balance of nature and to respect animals in their territory.

14 CLOSING WORDS

The skywalk CUMEO is at the pinnacle of paraglider development in the market for
intermediate gliders and shows what is possible regarding performance, safety and
innovation. It cost us a lot of time to develop this glider, but it was also a lot of fun.
In this development we recognize the challenge of making the right product for every
area and individual taste. We are pleased if you notice this during your first flight and if
you feel a certain unity with your glider from the very beginning.

The CUMEO will provide you with plenty of joy over many years if you treat it and care
for it properly. Respect for the demands and dangers of our sport are essential for
successful and beautiful flights. Even the safest paraglider can be dangerous due to
misjudgments of meteorological conditions or pilot error.

Always remember that flying sports are potentially risky and that you are responsible for
your own safety. We advise you to fly carefully and to respect laws in the interest of our
sport, because every pilot always flies at his or her own risk!

WE WISH YOU A LOT OF FUN WITH YOUR NEW GLIDER
AND ALWAYS HAPPY LANDINGS!!

Your skywalk Team
