DISCLAIMER
Free flying sports calls for appropriate training and a sound knowledge of the subject, as well as, of
course, the necessary insurance cover and licence. A pilot must be able to correctly assess the weather
conditions before taking off. Before every flight all items of equipment should be checked for damage and
airworthiness.
Every pilot bears sole responsibility for their participation in the sport. Neither the manufacturer nor the
seller of the reserve system can guarantee or be held responsible for the pilot’s safety.
INTENDED USE AND SAFETY REQUIREMENTS
This reserve system is a specially designed, manually released, reserve parachute for Paragliding,
Powered Paragliding and Hang Gliding activities. The use of this reserve is not permitted in connection
with any other flying activity such as parachuting, skydiving and base-jumping!

The required repacking interval may be reduced by extreme environmental influences like humidity,
sand, water, salt and other factors. If you are unsure about the effects of these, please ask a qualified
professional. The way to track the maintenance/rigging history of the reserve is its online logbook, which
will be automatically created for you when register the product (www.companion.aero/register).

, the wet reserve system should never be packed until it has air-dried
completely. If the reserve parachute is dried unevenly (lines or canopy), asymmetric shrinkage may occur!
The best procedure is to hang-dry the canopy upside-down, in a symmetric position (any distortions
should be avoided). Do not use any heat source or machine to assist drying!
If the reserve gets wet with sea salt water, the parachute should be rinsed out several times immediately
in fresh water and then dried! If a reserve is allowed to dry after salt-water immersion, the salt crystals will
damage the fabric and the lines, and this will compromise its airworthiness!

If the canopy shows signs of mildew or mould its strength might be affected, so it must be sent to the
distributor or manufacturer for inspection.
The intended life period of the reserve is 10 years. Even if you have never thrown it, we advise that you
replace the reserve after this period.
In addition, if you reach any of the conditions listed below, you should send in the reserve system for a

A factory inspection should be carried out only by a certified factory. Your local distributor will support
you in such a query. To ensure that the correct materials and techniques are used, any repairs should
only be carried out by the manufacturer.
STORAGE
The reserve should always be kept in a cool and dry place. Oil, grease, paint, solvents, acids and other
harmful substances should not be stored near the reserve parachute. For a long product lifespan avoid
unnecessary exposure to UV rays, heat and humidity. For maximum reliability throughout its entire
lifespan, always handle and maintain the SQR reserve with care. This advice applies whether the system is
mounted in your harness, or if you store it separately.
If you plan not to use your system for an extended period of time, you are advised to unpack the reserve
and store it loosely rolled up in a permeable bag.
After a long storage period (packed or unpacked) the canopy should be aired for 24 hours before re-
packing. The same applies if you have stored the reserve in an unsuitable environment.

DESIGNER NOTES
SQR - Square Round: The best of two worlds
The Hybrid SQR founds a new generation of reserve parachutes, which merges the advantages of the
classic round canopy and the cruciform version, to create an innovative and forward-looking technology.
The SQR has been newly developed from the start, and is precisely directed to meet the needs of pilots
and packers. Countless computer simulations and practical tests have been an essential part of an
extensive development process.
Advantages of the SQR at a glance:
•Improved opening behaviour, low descent values and high resistance to swinging as the result of
comprehensive practical tests and an aerodynamically refined canopy with optimized Air-Jets.
•Light weight due to careful choice of ideal materials and structure stiffness.
•Straightforward, reliable packing - similar to a round canopy – with comparatively few lines for easy
sorting, using practical packing aids and coloured packing guides.
•Not trimmed to track in flight.
•Tested for water landings! A mix of traditional and new materials with new low-shrink webbings
means that repeated full function is guaranteed after wet landings.
•Certified to both flight standards EN 12491:2001 and LTF NFL II 91/09 simultaneously, with the same
technical specs. for both standards!

1.Bridle:
At one end this connects the reserve to the harness, at the other to the canopy attachment lines.
2.Attachment lines can be regarded as two main groups:
Base lines (all the same length for easy packing) connect the bridle to the edge of the canopy.
Centre lines connect the bridle to the apex (middle) of the canopy.
The two groups are made with different materials and diameters, so they can be easily separated.
The lines are sewn with different thread colours on the

side, so they are easy to

3.Canopy:
Main canopy: made from several panels, with one red corner panel to make packing and sorting
easier.
Reinforcement webbings: at the edge of the canopy, and in some well-chosen places at the top.
Air-Jets: ideally placed at the four corners, giving the system active aerodynamic stability.
Packing loops: numbered and coloured blue on the top of the canopy (see picture 1).

– these distribute the shock loading

INSTALLING THE RESERVE
We recommend that you only allow a qualified person to install your reserve in a harness. To make sure
the installation will work a

is essential!
Every reserve/harness/container combination has its own peculiarities. It is essential that pilots and
packers/riggers familiarise themselves with the system and how it works – especially if any part of it is
new (new reserve in existing harness or vice versa) – so that reliable operation can be assured.
There are several ways to combine the reserve with a harness or external (front) container. Please ask a
qualified person if you are unsure about the best solution for your harness/container system. The harness
manufacturer provides reserve installation instructions in the harness/container manual.
