Maintenance, repairs and service

Packing
The paraglider must be folded cell to cell so that the plastic wires in
the cell walls at the leading edge lie flat on each other and don’t get
bent. This will give your SIGMA 8 a long life, and retain its fast, easy-
inflating takeoff qualities. When folding change the position of the
main L/R fold on a regular basis so that the same lane isn’t always on
the outside. Don’t squash or pack the glider too tightly.
Care and maintenance
Ultraviolet light, heat, humidity, sea water, aggressive cleaning
agents, unsuitable storing and physical abuse (dragging across the
ground) speed up the ageing process. The life of a paraglider can be
extended significantly by observing the following advice:
• Allow a wet or damp glider to dry by leaving it completely un-
packed at room temperature, or outside in the shade.
• If the glider gets wet with salt water rinse it thoroughly with fresh
water.
• Only clean the glider with fresh water, and a little neutral soap
if necessary. Do not use solvents under any circumstances.
• If the glider has been subjected to increased stress (such as
a tree landing) have it examined by an expert.
• Regularly remove sand, leaves, stones and snow from the cells.
Openings with Velcro closures are provided at the wing tips for this
purpose.
• Do not leave the glider out in the sun unnecessarily before and after
flight (UV light).
• Do not subject the packed glider to excessive temperature
fluctuations, and do ensure adequate air circulation to prevent con-
densation forming.
• Do not drag the glider across the ground.
• When landing, make sure that the canopy does not fall on its lead-
ing edge.
Lines
The SIGMA 8 A and B bottom lines are covered, so are well protected
from the higher degree of wear and tear in this area. The middle and
upper galleries are uncovered as well as the lower C lines. Their low-
er drag noticeably improves the glider’s performance, and the special
coating improves their resistance to UV radiation and abrasion. Nev-
ertheless, uncovered lines call for greater attention and care. Regular
checks of the glider are imperative. See section «Check».
