5. MAINTENANCE
& CHECKS
5.1. Maintenance & Checks
The life of your paraglider depends largely on the care with
which you maintain and use it. To maximize the life span of your
wing, respect the following rules:
• Avoid dropping the canopy on its top surface or on its leading
edge during inflation or landing.
• Don‘t drag it across the ground when moving it.
• Don‘t 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.
• Always use the protective bag to avoid direct contact with
the harnesses and buckles, and unwanted frictions inside the
rucksack.
• Never store your paraglider when it is damp. If immersed in
sea water, rinse it thoroughly in fresh water. Do not use any
detergents.
• Dry your paraglider away from direct light in a dry and well-
aired place.
• 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 vegetable or
animal origin (insects) can promote mould growth.METIS 4
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 particles. Check that you
reseal the debris release slot when completed.
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 nylon 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.
Trim tab replacement
It is common with all trim tab systems that after many hours of
flight with frequent trim tab adjustments, part of the webbing can
become worn. This can cause the trim tab system to eventually
slip from slow flight mode to faster mode when under load. This is
normal behaviour of any trim tab system that has endured heavy
use over time and suffered wear, such as that by commercial
pilots. METIS 4 trim tabs have been especially designed so that
this part of the trim tab system can easily be replaced.
Replacement method:
• We suggest that you replace one side completely first so that
you can use the other as a reference. (See photo 1)
• Release the Velcro of the ripstop buckle protector hood and
unthread the Velcro tab. (See photo 2)
• Very important:
this yellow line that is placed at the end
of the trim strap shall be on the same level as the edge of
double buckle. (see photo 3)
