Asofsummer2011,thismanualistobeusedinrelationtotheinterlockingstyletensioner.This

new tensioner can be identified buy its ORANGE safety guard.  Note: yellow guarded tensioner

requirestheuseofdifferentsetofinstructions,consultRiverhawkforassistance



TOAVOIDFAILURE,ENSURESAFETYANDPROPEROPERATIONTHETENSIONERANDINERLOCK

THETENSIONERASSEMBLYATANYPRESSUREUNLESSTHETOOLISINSTALLEDONTHEFLANGE.



WARNING

Impropertooluseandthefailuretofollowthecorrectproceduresaretheprimaryrootcausesoftool

failuresandpersonalinjuries.Alackoftrainingorexperiencecanleadtoincorrecthardware

installationorincorrecttooluse.Onlytrainedoperatorswithcareful,deliberateactionsshoulduse

hydraulictensioners.ContactRiverhawkCompanywithanytrainingneeds.



WARNING

Riskofhighpressurefluidinjection.Riverhawktoolsoperateunderhighpressure.Thoroughlyinspect

allhosesandconnectionsfordamageorleakspriortousingthisequipment.



CAUTION

Personalinjuryandequipmentdamagecanoccurifthepullerscrewisnotsecurelyengagedwith

theconicalthreadofthestud.Properengagementisachievedwhenthepullerscrewistightinthe



WARNING

Theproperpersonalprotectiveequipmentmustbewornatalltimes.Riverhawkrecommendsata

ThesafetyguardMUSTbeinplaceandhandskeptoutofdesignatedareasatalltimeswhenthe

tensionerispressurizedotherwisepersonalinjurycanoccur.



CAUTION

DONOTEXCEEDTHEMAXIMUMPRESSUREMARKEDONTHETENSIONER.Excessivepressurecan

damagethestudandthepullerscrew.



WARNING:

Keephandsclearofthetoolwhilethepressureisbuildingup.Thisincludesthepinwrenchfor

tighteningthespannerring(nut).Oncethetoolisstabilizedatpressurethenandonlythencanthe

nutbetightened.Thisreducesthepotentialofpersonalinjury.



Note:Beforethreadingthepullerscrewintothestud,carefullycheckthecleanlinessofboththe

stud's and the puller screw's conical threads. Apply a light coat of clean turbine oil or a spray

lubricanttothepullerscrew.Donotuse“NeverSeize”ontheconicalthreads.Thisprocedurewill

easeassemblyandassurepositivematingofthethreadsbeforetightening.

4.0GeneralPreparations



Readandunderstandallinstructionsbeforeinstallingandtensioningstuds



Thisequipmentproducesveryhighhydraulicpressuresandveryhighforces.Operatorsmust

exercisecaution,wearsafetyglassesandhardhatswhenusingthisequipment.



High‐pressurefluidfromtheHydraulicPressureKitsystempressurizesthetensionerwhich

generatesastretchingforcethatactuallystretchesthestud.Asthestudisstretchedthenutlifts

offtheflange.Thenutisthenreseatedintopositionontheflangebyturningspannerringwiththe

pinwrench.Whenthenutistightagainsttheflange,thepressureinthetensionerisreleased

leavingthestudloadedtoitspredeterminedvalue.



4.1MachinePreparation



Theflangetobetensionedmustbefullyclosedpriortopositioningofstudsintheflanges.Turning
