Transport and Storage 

Moisture is the worst enemy for your glider, adversely affecting the ageing of fabric, lines and 

reinforcements. The Boomerang 4 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 4 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:  
After 12 months or max. 100 flying hours, whichever is sooner. The Kevlar competition lines 

have to be replaced at the following intervals: Mainlines after 100 flying hours or 1 year and all 

lines after 200 flying hours or 2 years. 
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 provided with your glider. 

Damaged lines should be replaced by your GIN dealer. Before fitting a replacement line, check it 

for length against its counterpart on the other side of the wing. When a line has been replaced, 

always inflate the glider on flat ground to check that everything is in order before flying. 
Major repairs, such as replacing panels, should only be carried out by the distributor or 

manufacturer.
