If you damage a line:
Any line that is visually damaged MUST be replaced immediately. Do not y with damaged lines.
ReplacementlinescanbeorderedthemfromyourlocalOzonedealerordirectlyfromourwebsitehttp://
www.yozone.com/paragliders/en/shop/lines.php. Alternatively, use a reputable paragliding service
centretomakethereplacementlines.
It is important that replacementlines are made from the correct materialsand diameters. Youshould
checklengthsagainsttheircounterpartontheothersideofthewingtomakeensuresymmetry.Infactit
iswisetoalwaysreplacebothsidestoensuresymmetry.Oncethelineshavebeenreplaced,inateand
carefullycheckthewingbeforeying.
Maintenance Checks
Yourwing,likeacar,shouldbetechnicallycheckedtoensureproperairworthiness.Yourwingshouldbe
checkedbyaqualiedprofessionalforthersttimeafter24months,orafter100hours.However,ifyou
areafrequentyer(morethan100hrsperyear),thenwerecommend,thatyougetyourgliderchecked
annually.Thecheckershouldinformyouabouttheconditionofyourgliderandifsomepartswillneedto
becheckedorchangedbeforethenextnormalservicecheckperiod.
Thesailandthelinesdonotageinthesamewayoratthesamerate;itispossiblethatyoumayhaveto
changepartorallofthelinesduringthewing’slife.Forthisreasonitisimportanttodoregularinspections
so that you know the exact condition of all of the components of your glider. We recommend that
inspectionsarecarriedoutbyaqualiedprofessional.
Youaloneareresponsibleforyouryingkitandyoursafetydependsonit.Takecareofyourequipment
andhaveitregularlyinspected.Changesinination/groundhandling/yingbehaviourindicatesthegliders
aging,ifyounotice anychangesyoushouldhave thewingcheckedbeforeying again. Thesearethe
basicelementsofthecheckup(fulldetailsandpermissiblegurescanbefoundonourwebsite):
Porosityis measuredwith aporosity meter,the timetaken bya certainvolume ofair togo througha
certainsurfaceofthecloth.Thetimeinsecondsistheresult.Ameasurementisdoneinaseveralplaces
onthetopsurfacealongthespanofthegliderbehindtheleadingedge.
The tearing resistance of the cloth - A non-destructive test following the TS-108 standard which
speciesminimumtearstrengthforskydivingcanopiesshouldbemadeusingaBettsometer.(B.M.A.A.
ApprovedPatentNo.GB2270768CliveBettsSails).
Strength of the lines -Anupper,middleandlowerAline,alongwithalowerBlineshouldbetestedfor
strength.Eachlineistestedtobreakingpointandthevaluerecorded.Theminimumvalueis14Gforall
A+Blines,calculatedfromthemaximumcertiedyingweightoftheglider.Theaddedminimumstrength
forthemiddlelinesandforthetoplinesshouldbethesame.Ifthebreakingstrengthistooclosetothe
minimum valuecalculated, the professional should give a period after which you will have to test the
strengthofthelinesagain.
Lengths of the lines-Theoveralllength(riserlines+midlines+upperlines)hastobecheckedunder
5Kgsoftension.Thedifferencebetweenthemeasuredlengthandtheoriginallengthshouldnotexceed
+/-10mm.ThechangesthatcouldappearareaslightshrinkontheB’sand/oraslightstretchontheA’s.
Theconsequencesofthesechangescanincludeaslowertrimspeed,difcultinationetc.
Risers-Visualinspectionforsignsofwearorabrasion.Differencestomanuallengthsshouldnotexceed
+/-5mm.
Canopy check-Afullvisualcheckshouldbecarriedout:Allthecomponentsofthewing(stitching,ribs,
diagonals,lines,tabs,...)shouldbecheckedforsignsofdeterioration.
Finally,aight test toconrmthatthewingbehavesnormallyshouldbecarriedoutbyaprofessional.
Modifications
YourOzoneZenohasbeencarefullydesignedandtrimmedtogivetheoptimumbalanceofperformance,
handlingandsafety.Any modication resultsinthegliderlosingits certication andwillalsomakethe
wing more difcult and dangerous to y. For these reasons, we strongly recommend that you do not
modifyyourgliderinanyway.
IMPORTANT
Take care of your
glider and make sure
you have it checked
and serviced according
to the schedule.
