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INTERLOCK

SAFETYGUARDMUSTINSTALLEDONTHEFLANGEBEFORETENSIONINGBEGINS.DONOTUSE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

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

inthestudandisnotcross‐threadedintotheconicalthread.(ReferenceIM‐220)

WARNING

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

minimum,safetyglasses,longsleeveshirt,hardhat,heavyworkgloves,andsteeltoeshoes.



WARNING

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

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

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,andproperpersonalsafetyequipmentmustbewornatalltimes.Contactthe



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

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
