 absorb water. Mould may form if the paraglider is stored wet and the 

fi

bres may rot, particularly when 

 it is warm. This can make the paraglider unsuitable for 

fl

ying within a short time. 

 A brand-new glider will often be compressed when delivered. This is solely for the initial delivery 

 and the glider should not be compressed in such a way again. Do not pack your glider too tightly after 
 use and, even though it is very comfortable, never sit on the backpack with the glider inside. 

 If salt water gets on the glider, it should be rinsed immediately in fresh water (refer to the section 

 “Cleaning”). 

 The Boomerang 12 has various different high-quality and accurately manufactured lines which have 
 been selected according to the load and area of use. You should also protect the lines from 
 unnecessary UV light because, as with the fabric, UV light in particular will weaken the lines. 

 Dyneema lines, for example, are very temperature-sensitive and can be permanently damaged at 

 temperatures above 75° C. Therefore your glider should never be stored in a hot car especially during 
 summer. 

 Be careful that there is no abrasion caused to the coating on the lines by rubbing, particularly when 

 ground-training with crossed risers. 

 Do not walk on the lines after the glider has been spread out and watch out for spectators or skiers 

 who may inadvertently go over the lines. 

 When you are packing up the glider, be careful to avoid putting any unnecessary kinks in the lines 

 and use only the overhand knot or bowline knots described for the brake lines. 

  

 Various forms of plastic rods are used in the Boomerang 12 (rigid construction), which help maintain 
 the shape of the leading edge and the stability of the canopy. To ensure that the plastic rods keep 
 their shape, it is important that you pack the glider as described in the section “Packing the 
 paraglider”. 

 The plastic rods on the Boomerang 12 can all be replaced through small pockets. If you notice that a 

 plastic rod has been damaged or misshapen because of incorrect use, this can be replaced by Gin 
 Gliders or a Gin Gliders authorised workshop. 

 If you do have to clean the glider, use only lukewarm fresh water and a soft sponge. Use a weak soap 
 solution for stubborn stains, and then rinse it out carefully and thoroughly. Leave the glider to dry in a 
 place which is well-ventilated and in the shade. 

 Do not under any circumstances use chemicals, brushes, rough cloths, high-pressure cleaners or 

 steamers to clean the glider, as these can damage the fabric coating and weaken it. The glider 
 becomes porous and loses breaking strength. 

 Do not under any circumstances put the glider in the washing machine. Even if washing powder is 

 not used, the glider would be badly damaged by the mechanical action of the machine. Do not put the 
 canopy into a swimming pool - chlorine will damage the fabric. If you have no choice but to rinse the 
 glider, e.g. following a landing in the sea, gently wash it down inside and out with fresh water. 
 Frequent rinsing accelerates the aging process.
