Storage and transport
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 lid off so that air can
circulate around the packed canopy. Make sure no mice or cats make their sleeping quarters in
your wing, and keep it well distant from solvents and acids. Petrol and other petrochemicals are
especially abrasive for nylon and will dissolve the cloth if allowed near.
The storage temperature should be between 10 and 25 degrees Celsius, and the relative humidity
between 50 and 75%.
Do not expose your UP Meru to extreme heat (storing it the boot of a car parked in the sun). The
heat may cause moisture to be pressed through the fabric, thereby damaging the coating. 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.
Cleaning
If you feel it necessary to clean your UP Meru at any time then use lots of lukewarm water and a
soft sponge. More stubborn stains can be cleaned with a weak soap solution, and rinsed
thoroughly. Then leave it to dry in a shady but well-ventilated area.
BEWARE! Never use chemical cleaning agents, brushes or hard sponges on the material,
as these destroy the coating and affect the strength of the cloth.The canopy will become
porous and will lose structural strength. Never attempt to clean your paraglider in a
washing machine. Even without using detergents the simple mechanical abrasion will quickly
finish the canopy and render it useless. Also avoid dipping it in a swimming pool; the chlorine will
damage the cloth. If you HAVE TO rinse the canopy, for example following a sea water landing,
do so with a gentle spray of fresh water. Frequent spraying will accelerate the ageing process.
Checks and repairs
Repairs and periodic checks should ONLY be carried out by UP, or by UP approved
checking centres. Failure to comply with this will forfeit the certification. Consult:
www.up-paragliders.com under Service to find a check centre near you.
At UP we invest our entire knowhow in paragliding into making the sport safer for you. We
offer a variety of services all centred around safety to our customers.
Maintenance
All care and maintenance must be carried out in accordance with UP recommendations. To
ensure that this happens we strongly advise you to only let UP recognised service centres touch
your wing – this is also a prerequisite for the UP warranty to be valid. So there’s a lot speaking for
letting UP, or a UP affiliate, look after your Meru!
Symmetry Check / Performance Check
Due to their design, two-liners react more sensitively to changes in length of the lines. You can
easily determine whether line lengths have changed on your Meru due to unavoidable external
influences: the A- and C-level main lines have the same length in pairs. Fix the riser and compare
the Amain1 / Cmain1, Amain2 / Cmain2 and Amain3 / Cmain3 lengths on both sides with about 5
kg of strain on the lines. The respective line pairings should not deviate more than 10mm from
each other. If the respective C-line has shortened by more than 10mm compared to the
