II‐OP.7ProceedwiththeOPprogram.Itisrecommended
thatthetirebeturnedoverontherim.OP.7‐IIProceed
withtheOPprogram.Itisrecommendedtoshiftthetire

cannotbeimproved.PressSTOP(5)toexit.However,itis
possibletoreadjustthetirerelativetotherimtoachieve
significantweightminimization(i.e.:smallerbalance
weights)withouthavinganadverseeffectonsilent
running.Dependingonthereadings,thereareseveral
possibilitiesforproceedingwiththeprogram.These
possibilitiesaredescribedbelow.ReadingII‐OP.7(Fig.
5‐37).Turnthetireoverontherim(theleftdisplaybars
arerotating).Option1:Turnthetireoverontherim
(normalprogram).Readjustthewheelaccordingtothe
leftdirectionindicatorandmake adoublemarkonthe
leftsideofthetireexactlyperpendiculartoandabove
themainshaft.Removethewheelfromthemachine.
Turnthetireoverontherimandreadjustuntilthe
doublemarkcoincideswiththevalve.Clampthewheel
onthebalancerandreadjustitsothatthevalveisexactly
perpendiculartoandabovethemainshaft.Pressthe
ENTERkey(1)toacquirethevalveposition.ReadingOP.8
appears(Fig.5‐34).Spinthewheel(START).Ifbalancing
optimization(silentrunning)hasbeencarriedout
correctly(accordingtotheprogramcycle),after thecheck
runthemachineautomaticallyreturnstothetypeof
weightpositioningpreviouslyselectedandindicatesthe
residualdynamicimbalanceonthewheel.Balancethe
wheelaccordingtothereadings.Bothoptimizationand
balancingareaccomplished.
