an asymmetric or frontal collapse. Active piloting will reduce the
loss of altitude and a change of direction.
In the event of a frontal (symmetric) collapse:
• Before automatic reopening occurs, bring both brakes
down swiftly & symmetrically to speed up reopening of the
leading edge, then immediately bring your hands back up
to normal flying position.
In the event of an asymmetric collapse:
• Keep the paraglider flying as straight as possible by lean-
ing away from the collapsed side and applying sufficient
(just enough, not too much) brake to maintain course.
• Speed up the reopening of the closed side by a single,
positive input on the collapsed side & repeat if necessary.

6.2 Stalls

Certain pilot behaviour or weather conditions can cause a full
stall. This is a serious deviation from normal flight and can be
difficult to manage. If a stall occurs at less than 100 m above
the ground, throw your reserve parachute.
Main Causes of a Full Stall:
• Poorly timed or excessive use of the brakes when the air
speed of the wing is reduced (e. g. when coming out of a
spiral or speeding up after a B-line stall).
Rain-induced deep or Full stall:
• A soaked or heavily drenched leading edge (from rain or a
cloud) can result in a full stall or Deep stall due to uneven
airflow over the leading edge as a result of rain drops and
an increase of weight to the wing. Reported cases of this
phenomenon are linked to high levels of porosity in the
glider's fabric. Whatever the cause, a stall can be either
symmetrical or asymmetric (a spin). In both cases the
brake line travel becomes very short and even small input
may suddenly induce an airflow separation; in some cases
even a gust or a sudden thermal may change the angle
of incidence enough to cause the deep stall. If you find
yourself flying in unavoidable rain we strongly recommend
that you avoid any sudden movements or radical brake line
input, that you do not pull Big Ears or B-stall, and that you
steer clear of turbulence and avoid a deep flare on landing.
In both cases the pilot has two possible courses of action:
• If the full stall happens above 100 m it is strongly recom-
mended to initiate standard stall recovery assuming the
pilot is familiar with the process (i.e. a complete execution
of the full stall, stabilization of the wing and progressive
lifting of the hands to resume normal flight).
• If the full stall happens below 100 m or if the pilot is unfa-
miliar with stall recovery the reserve parachute should be
deployed immediately
6.3 Brake line malfunction
If a brake line or pulley breaks it is possible to fly CIMA PWR
using the D risers (rear risers). The movements should be finely
controlled as the deformation of the wing due to the traction on
the D risers is greater than that produced by using the brakes.
Tip: Practice this method of steering to be prepared before
a real brake failure!
7 . MAINTENANCE &
CHECKS
7.1 Advice on Maintenance
• Avoid dropping the canopy on its top surface or on its
leading edge during inflation or landing. Do not drag it
across the ground when moving it.
• Do not expose it unnecessarily to sunlight.
• Choose a folding technique that doesn't damage the
leading edge strips and that doesn't crease the internal

structure excessively. To maximize the life of your glider we
do not recommend the use of stuff sacks: the abrasion of
the material will decrease the life expectancy of the fabric –
in particular its internal structure.
• Never store your paraglider when it is damp. If immersed in
sea water, rinse it thoroughly in fresh water. Do not use any
detergents.
• If you do most of your flying near the sea, where the air is
humid and salty, the wing may age faster. In this case we
suggest you have it checked more often than prescribed in
this manual.
• Empty any foreign bodies from your paraglider regularly, for
example sand, stones or animal or vegetable matter which
may eventually decay. Twigs, sand, pebbles, etc. damage
tissue in successive folds, and organic debris of vegeta-
ble or animal origin (insects) can promote mould growth.
CIMA PWR is fitted with debris release slots at the wing
tips. Debris can be shaken from the closed cells through
to the wing tip and the release slot opened to remove parti-
cles. Check that you reseal the debris release slot when
completed.

7.2 Storage and transport

Store your loosely packed glider in a cool (10-25°C) and dry (<
70% humidity) place. Hot car boots or damp basements lead
to damaging of the cloth. A paraglider should always be dry
when packed, but this is particularly important after the last
flight of the season. But even a completely dry wing should
still be stored open in a dry, clean and dark place. If you do not
have room for such winter storage we recommend you open
all compression straps on the bag as much as possible and
leave the bag open so that air can circulate around the packed
canopy. Make sure no vermin make their sleeping quarters in
your wing, and keep it well distant from solvents and acids.
Petrol and other petrochemicals are especially abrasive for ny-
lon and will dissolve the cloth if allowed near. High temperatures
in combination with moisture are a particularly volatile mix that
will accelerate the hydrolysis process where the fibres and the
coating are decomposed.
