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

andLTFtestedspecimenbeforeitleavesthe factory.
Speed System
Thespeed system increases themaximumspeedbyloweringtheangleofattackwith apulley-
guided,foot-operated system.Approx. 10km/hgain in speed canberealized withthe
accelerator at full travel.

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

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.

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.

Connectthe risers to yourharnesscarabiners, ensuringthere are no twistsorloops
aroundthe lines.
Connectthe speed system tothe riserswiththe Brummelhooks.

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

An impulse launch where you startrunningwithslacklinesclose to the glider isnot needed.
