Care Maintenance and Repairs The materials used in the Boomerang Sport have been carefully selected for maximum durability and performance Nevertheless following the guidelines below will keep your paraglider airworthy and will ensure a long period of continuous safe operation Excessive wear is caused by careless ground handling and packing unnecessary exposure to UV light chemicals heat and moisture Ground handling The following should be avoided Violent shocks to the upper surface e g when the canopy crashes to the ground leading edge first whilst ground handling Dragging the glider along the ground Stepping on the lines or canopy The Kevlar line can take lots of pulling force without stretching but is sensitive to bending with small radius Opening your wing in strong winds without first untangling the lines UV damage Avoid leaving the glider and your lines out in the sun unnecessarily UV rays from the sun degrade paraglider cloth and weaken Kevlar lines rapidly Packing instructions We advise you to pack the glider accordion wise as shown in the diagram This packing procedure takes slightly longer and is easier with an assistant but it conserves the rigidity in the profile reinforcements and the Rigifoils Since folding the glider weakens the materials pack the glider as loosely as possible 16 BGIN Transport and Storage Moisture is the worst enemy for your glider adversely affecting the ageing
3. forbidden Besides the inherent risks extreme manoeuvres of any kind place unnecessary stress on the glider and effectively shorten its lifespan We strongly recommend no acro flying or unnecessary manoeuvres on the Boomerang Sport to avoid weakening your glider and especially it s lines Landing with the Boomerang Sport Select a familiar landing area free of obstacles and carefully note the wind speed and direction in the landing area The minimum flying speed and big flaring reserve of the Boomerang Sport will help you to make a soft landing in all conditions Approach the landing with sufficient airspeed and don t leave your last turn too late or too steep Before landing slide your legs forward in the harness so that you adopt the standing position NEVER land in the seated position it is very dangerous for your back even if you have back protection which is only a passive safety system Standing up before landing is an active safety system and is much more effective Tow launch The Boomerang Sport is suitable for towing by pilots who have the relevant towing rating The Boomerang Sport has no tendencies towards deep stall parachuting There is sufficient margin to counter steer the glider in a normal towing situation Make sure you use proper equipment experienced personnel the recommended techniques and all relevant safety precautions for towing Motorized flight Motorized flying with the Boomerang Sport is not recommended 5
4. of fabric lines and reinforcements The Boomerang Sport should therefore be kept dry and cool Do not pack the glider away for a prolonged period if it is damp sandy salty or if other objects have entered the cells Always allow it to dry naturally before storage in a dry room Leave the rucksack zip open whenever possible to allow residual moisture to evaporate and do not transport or store the glider in the proximity of chemicals such as gasoline paints or other solvents Cleaning Use only lukewarm water and a soft cloth to clean your wing Never use any abrasive materials or detergents Only clean the wing if it is absolutely necessary e g after a landing in salt water Maintenance Inspections GIN Gliders require the Boomerang Sport to be inspected by an authorized Gin agent after every 100 hours flying time or every year whichever is sooner A full inspection is required for every 24 months The maintenance instructions which can be downloaded at www gingliders com have to be observed A full inspection will give you peace of mind and extend your glider s lifetime Additional inspections should be performed by a qualified person following a crash or violent landing on the leading edge or if you note a deterioration of performance or behaviour You should also check for any damage to your lines sail risers and connectors before each flight Repairs Very small holes in the sail can be repaired with the sticky back tape provide
