3. Before you Fly
Pre-delivery Inspection
The Bolero 4 is deliveredwith speed system, rucksack, inner bag, riser cover,compression strap,
repairtapeandthis manual. Yourinstructorordealershouldhavemade atestinflation
followedbyatestflight before delivery. Each Bolero4 ischeckedfor conformity withtheEN
andLTFtestedspecimenbeforeitleavesthe factory.
Speed System
Thespeed system increases themaximumspeedbyloweringtheangleofattackwith apulley-
guided,foot-operated system.Approx. 10km/hgain in speed canberealized withthe
accelerator at full travel.
Itisimportanttohaveyour acceleratorsystemcorrectly routedthroughyourharnessand
attached to the risers with the supplied Brummelhooks.Thelengthofthespeedbarshouldbe
initially adjustedwhile on the ground, sitting in the harness sothat the legs are fully extended

Brake line adjustment
Themainbrakeline lengthsof theBolero 4 correspondtotheones usedin theEN and LTF test
flights. These linelengthshave been finetunedby GINtestpilots,anditshouldnotbe
necessarytoadjust them.
In soaring flight,it is common tofly with half awrapon the brakes.However, careshould be
takentoreleasethewraps in anyextremesituation.
Ifyoudo needto make adjustmentsto suityourharness,bodyandflying style,westrongly
recommendthatyoutestflytheglider
withevery2cm ofadjustment.There
should be a minimum of 10cmof free
braketravelwhen theglider isflown
hands-off.Thispreventsthebrakesbeing
appliedunintentionallywhen thespeed

Rucksack
AllGinglidersaredeliveredwith adurableripstopKODURA®rucksack,designed forergonomic
carryingcomfort andeaseof use.
Therucksack shouldbepackedcarefullytoachieve maximum comfort.First,placetheglider
insidethe harnessandthen put the top of harness in thebottomoftherucksackwith the glider
side nextto the backof the rucksack.Finally, tighten theinternaland externalcompression
strapsandadjusttheshoulder andwaiststrapsto ensure theequipment stays firmlyinplace
whenwalking.Therearealsotwostorage pockets for accessories.
AnXXLrucksack(200L capacity) is availableasanoptional extraforpilotsthat requireit.

Your harness
TheBolero 4 hasbeen testedwithaharness withavariable cheststrapandwithout fixed
cross-bracing. Olderharnesseswithfixedcross-bracingarenotsuitablefor flying with the
Bolero4andshouldnotbeused.Checkwith themanufacturer of the harnessor your
paraglidinginstructorifindoubt.
Theadjustment oftheharnesschest strap controls the distance between carabiners and affects
thehandlingandstabilityoftheglider. Tighteningthe cheststrapincreases stability,
lengthening it gives morefeedback from the gliderdecreasesstability.
Gin calculates and draws the planof the glider withadistancebetweenthe carabiners of 44cm.
Werecommendasettinga distanceof 42cmto50cmbetweenthecarabiners,dependingonthe
sizeanddesignoftheharness.There isno needto flywith atightcheststrapsettingwiththe
Bolero 4, asthere is no tendency for it tofeel unstable, unlike older gliders.
Certified Weight Range
The Bolero 4 must be flownwithin thecertified weight rangegivenin thereferencesectionat
the back ofthis manual.The weight rangeis quoted asthetotal weightinflight,i.e.theweight
of the pilot,glider, harness and accessories. Theeasiestwayto check yourtotalweightisto

4. Flying the Bolero 4
Werecommendthatyoufirstpracticeinflating yourglider on a smalltraininghill,orflat
ground.Make your firstflightswith yournewparaglideringentleconditionson a familiar
flyingsite.
Preparation for launch
Following a consistent method of preparationandpre-flight checks isvitalforsafeflying.We
recommendthefollowing:
Onarrivalattheflyingsite,assessthesuitabilityofthe conditions:windspeed and
direction, airspace,turbulenceandthermalcycles.
Inspect yourglider, harness,reservehandleandpin,helmetand anyother equipment.
Chooseasufficiently largetake-offareawithevenground and no obstacles.
Laytheglideroutaccordingtotheplanform, andgetthe lines andrisers sorted out.
Secureyourselfinyourharnessand don’t forgetthelegloops!Putyourhelmeton.
Connectthe risers to yourharnesscarabiners, ensuringthere are no twistsorloops
aroundthe lines.
Connectthe speed system tothe riserswiththe Brummelhooks.
Doafinalline check by pullinggentlyontherisersorlines to ensure therearenonew
knots,tangles orinterferingbranchesorrocks.Take extra careinnilorlightwinds.
Pre-flightchecklist
Reserveparachute:pin in andhandle secure.
Helmet and harness bucklesclosed.
Linesfree.
Canopyopen and into wind.
Airspaceclear.
Take off
The keyto a successful launch techniqueis to practicegroundhandlingon flat ground whenever
youcan.
Light or Nil Wind Launch
TheBolero 4 inflatessteadilyinnil-windconditions. Simplyguidethegliderwith the A-risers,
keepingyourarmsbentandhands at theleveloftheshoulders. Allowyour armstoriseinan
arcandwaitfortheglider toinflate and come above yourhead–do not push therisers. There
is no need to pull the risers hard. Run positivelyasthe glidercomesaboveyour head. Be sure
tolookupandcheck that the canopy is fully inflated before you take-off, and thatthereare
notanglesinthelines.If any irregularityshouldoccurandyou’renot yet airborne, abort the
launchimmediatelyby stalling theglider. On steep launches,stallone sideofthegliderand run
parallelto the hill.
Iftheglidershould come upsideways,and the situationisrecoverable,runtowards the lower
sideratherthantryingtostruggleagainsttheforce.
An impulse launch where you startrunningwithslacklinesclose to the glider isnot needed.

11
Strong Wind Launch
Thereverse launch techniqueis recommended. Holding thebrakes,turnaroundto face the wing
passingonesetofrisersoveryour headasyouturn.Wesuggestbuilding a"wall" bypartially
inflatingyourgliderontheground, thussortinglinesoutthoroughly. Check the airspaceis
clearandgentlypulltheglider up withthe A risers. When thegliderisoverhead,check itgently
withthebrakes, turnand launch.Instronger winds, bepreparedto take a couple of steps
towards thegliderasit inflatesandrises.
Line knots or tangles
Ifyoudotakeoffwith a lineknotortangle,trytogetclearof the ground andany trafficbefore
takingcorrectiveaction.Weight shift and/or counterbrake to the oppositesideandpumpthe
knottedsidewithyourbrake.Be carefulnot toflytoo slowlyto avoidastallor spin.Iftheknot
ortangleistootighttopumpout,immediatelyfly to thelanding zoneandlandsafely.
Min Sink / best glide
Theminimum sink speed isachievedbypullingapproximately 30 cm of brake.The theoretical
bestglidespeedincalmairisrealizedat thehands-offposition.
Accelerated flight
Onceyouhave become accustomedto flying theBolero 4, you can practiceusingthe speed
system, which allows improved glide in headwinds and greater penetrationinstrongwinds.
Applythespeedsystembypushing the speedbarprogressively with yourfeet. Be preparedto
controlrollby usingweightshiftandpitchbyvaryingtheamountofbar.Keep a very light
pressureon thebrakesinorderto feelthe canopy.
Avoidflyingacceleratedneartheground,anddon’tuse morethan half the maximumtravel in
turbulence.
Ifyoudo encounteracollapsewhileusingthe accelerator, step offthe bar firstbefore taking
anyothercorrectiveactions.
Active Flying
TheBolero 4 hasahigh internalpressure,resistancetotuckingand a veryhigh degreeof
passivesafety. However,it isrecommendedthat atthisstage youalready start practising an
activeflying style.This willhelpyouavoid deflations in all but themost turbulentconditions.
Thekeyto active piloting iskeeping the glideraboveyourheadatalltimes. If it fallsback
behindyou,letupthebrakes.Ifit surgesin front ofyou, counterbrakeuntilthesurge is
controlled. If yousense a lossof pressure on onesideof thecanopy,smoothlyapplybrake
and/orweight shifton the appropriatesideuntilyou feel pressure return. In all cases,maintain
adequateairspeedandavoidoverreaction.
In turbulence
Deflationsofthecanopycanoccurin strongturbulence.TheBolero4 will recoverwithout pilot
inputinalmostallsituations,sowheneverindoubt,letupthe brakesand let the glider fly.

12
However,it isrecommendedthatyoufollowthe advice below in order tohelp the wingrecover
morerapidly.
Asymmetricdeflation
Intheeventof encountering strong turbulence andsufferinganasymmetricdeflation(collapse
on oneside), the Bolero 4 will promptlyand easily re-inflatewithout interference from thepilot,
butthecourse might alterslightly. Thismight beunwantedcloseto theground orothergliders.
Maintain your course by weightshifting away from thecollapsedside. This action can be aided
byapplyinga littleforceon thebrakeoppositetothedeflation. This will normallybesufficient.
However,if thedeflation failsto come out, pumpthedeflatedside with a firmandsmooth
pumpingmotion.Letthegliderregainitsflyingspeedafterithasre-inflated.
Symmetricdeflation
Asymmetric(frontal)deflationwill comeout promptly without pilotinput.Thegliderwill
regain airspeed with a small surge.Ifcounterbraking,becarefulnotto over-correct.
Cravat/ glider wrappedaroundlines
Acravatoccursafter aseveredeflation whenthe wingtip becomes trappedinthegliderlines. It
is extremelyunlikely tooccur on theBolero4.Nevertheless,the pilot shouldbefamiliar with
theprocedureforcorrecting it.Counterbrake and/or weightshift and pumpthebrakeon the
tangledside. On all Gin gliders,thereisaseparatestabilizer/wingletmainline. On the Bolero4
itgoesdown to theBriser.Thisline usually comesslack in theeventof a cravat.Pullitdown
completelyuntilitcomestightandthecravatnormallycomesout.
Cascade of events
Many reserve deployments are a result ofacascadeofover-correctionsbythepilot.Please
notethatover-correctionsareoften worsethannoinput atall.
Flatspin
Innormalthermalling flight, you are very farfromthelimits of aflatspin. Nevertheless,should
this occur,just let up the brakesand waitforthe glider to surgeforward.

13
Fullstall,dynamicstall
Thisis an extrememanoeuvreandthereshouldneverbeany need to perform one.
Donottakewrapswith your brakesbeforeentering a fullstall.Keepyourhandsclosetoyour
bodyduring the stall,and lockthemunderyourharnessseatplate ifnecessary. In a stable full
stall,the canopywill oscillatebackandforth.Before releasing thestall,raiseyourhands
slightly andevenlyto fillthe gliderwithair.If possible, let thebrakesup when the gliderisin
frontofyoutoavoidexcessivesurge. The Bolero 4will slow downthesurgeon its own,but you
maycounter brakethedivebrieflyfor comfortifneededand then let up the brakestoregain
airspeed.Becarefultonot stallthe glideragainwhendampingthesurge.
Neverattemptastall and then changeyour mind and release thebrakes,as thegliderwill surge
radically.
Deepstall (parachuting,stablestall)
TheBolero 4 doesnot have a tendencytogetintonor stayin a deep stall.Shouldthis
neverthelessoccur,putyourhandsonthe Arisersandpushforwardtogainspeed.Onsome
modernharness/accelerator setups, you canreachthe speedbar without usingyourhands. Ifso,
pushthespeedbar.Nevertrytosteeroutof adeepstall.
Youcanrecogniseadeep stall by the glidergetting"mushy"and the airflow around your ears
decreasing.Thissituationis usuallyachievedbyflying in turbulenceorexitingadeflation with
toomuchbrakesapplied.
Losing altitude
Extremelystrongand widespreadliftisfound,forexample,instormconditions. Thebestplace
tobe inthis situation is on the ground.Nevertheless,ifyou’vebeen caught out bytheweather
andfind yourselfneeding to descendrapidly, thereareseveral waysto do so.Thebest way is,
ofcourse,tofindsink.Failingthat,tryoneofthetechniquesbelow.Theyarepresentedinorder,
fromtheleasttothemostextreme. Most ofthesetechniques placeunduestressonyourglider,
andshouldbe avoided if your wish to extendits lifetime.We recommend you initially practice
these manoeuvres under qualified supervision during a safety training course.

Althoughthenoiseofthewindaroundyour ears may indicate theairspeed improves, the
airspeed doesnot improve with big ears.You mayusethespeedbarincombinationwith big
earstomaintain your forward speed but increase thesink.
Theglider can be steeredwhile in bigears usingweight shiftalone.
Whenreleasing thelines, theBolero4’s earswill come out ontheir own.Releasethebigearsat

Motorized flight
EN andLTF tests of paragliders do not include motorizedflight.However,motorized flyinghas
beenmadewith great success due to itsveryeasytake-offcharacteristics,good performance,
stabilityand extraordinarily good handling.Alwaysusecertified combinationsof

5. Care, Maintenance and Repairs
The materialsused inthe Bolero4 have been carefullyselectedformaximumdurability.
Nevertheless,followingtheguidelinesbelowwill keep your paragliderairworthyand will
ensurealongperiodofcontinuoussafeoperation. Excessiveweariscaused bycarelessground
handlingandpacking,unnecessaryexposuretoUVlight,chemicals,heatandmoisture.
Ground handling
Thefollowingshouldbeavoided:
Violent shockstothe upper surface(e.g. when the canopy crashesto the ground leading
edgefirst whilstgroundhandling).
Draggingthe glideralongtheground.
Stepping on thelinesor canopy.The Kevlar inside the sheath can take lotsof pullingforce
withoutstretching, but is sensitiveto bendingwithsmallradius.
Openingyourwingin strongwindswithout firstuntanglingthelines.
UV damage
Avoidleavingtheglideroutinthesununnecessarily.UVraysfromthesun degradeparaglider
cloth.
Packing instructions
Weadviseyou to pack theglider‘accordion wise’asshowninthe diagram. Thispacking
procedure takesslightly longer andrequires an assistant, butit conservestherigidityin the
profilereinforcements.
Since folding the glider weakensthematerials, pack theglider as looselyaspossible.

17
Transport and Storage
Moisture is the worstenemyforyourglider, adverselyaffecting the ageing of fabric,linesand
reinforcements.TheBolero 4should therefore bekept dry and cool.Donotpack theglider away
fora prolongedperiodifitisdamp,sandy,salty,orifother objects have entered the cells.
Alwaysallow ittodrynaturally beforestorageinadryroom.Leavetherucksack zip open
whenever possible toallow residual moistureto evaporate, anddo not transportorstorethe
gliderintheproximity of chemicals such as gasoline, paintsor other solvents.
Cleaning
Useonlylukewarm water andasoftclothtocleanyourwing.Neveruseany abrasivematerials
or detergents. Only clean the wing if it is absolutely necessary e.g. after a landing in salt water.
Inspections
TheBolero 4 should befullyinspected by an authorized Gin agentafterevery100 hours flying
timeoreveryyear,whichever issooner.Afullinspectionwill give youpeaceofmind and
extendyourglider'slifetime.Additionalinspectionsshouldbeperformedby aqualifiedperson
following a crashorviolent landingontheleadingedge,orifyounoteadeteriorationof
performanceorbehaviour.
Youshouldalsocheck for any damage to yourlines,sail,andcarabinersbeforeeachflight.
Repairs
Verysmallholesinthesailcan be repairedwiththe sticky back tapeprovided with yourglider.

check it forlength againstitscounterpart on theothersideof the wing. Whena line hasbeen
replaced,alwaysinflate theglideron flatground to checkthateverythingisinorderbefore
flying.
Major repairs, such asreplacement panels, shouldonlybecarriedoutbythedistributoror
manufacturer.
Environmentally friendly disposal of the paraglider
Whenthisparaglidercannotbeusedany longerafteran extendedperiodoftime,thenyoumust
ensure that itwill be disposed in an environmentally friendlyway. Pleaseobservethe existing
regulationsandlawsin your country.
