Maintenance...
1. Checkthetightnessoftheconnectionsbetweenthejawhousingcoupler,
 nut,jawhousing,andthehydraulicplunger,thenosepiece,theheadand
 thelocknut.
2. If the jaws show excessive wear and/or are dirty, follow the steps
 providedintheservicingproceduressection.
Troubleshooting...
1. Rivet mandrel is gripped by the jaws but the rivet can not be set
and mandrel can not be bro ken:
CAUSE:Lowairpressureorlossofhydraulicfluid.
REMEDY:Increaseairpressureto7bar(100PSI)maximumattool.Make
sureallfittingsincludingrearglandandheadaretight.Ifmalfunction
persists,callauthorizedSunexTools
®
warrantycenter.
2. Mandrel does not fit completely into nosepiece or fails to eject:
CAUSE:JawHousingdistanceincorrect.
REMEDY:Loosentheheadandchecktheratedstrokelength.
Ifshorter,searchforwornordamagedO-ringsandreplaceit.
CAUSE:Jawsaredirtyordamaged.
REMEDY:Cleanorreplacethejaws.
CAUSE: Fatiguedjawpusherspring.
REMEDY:Replacethejawpusherspring.
CAUSE:FatiguedReturnSpring.
REMEDY:Replacethereturnspring.
CAUSE:Airleakageinvacuumsystem.
REMEDY:Searchforwornordamagedsealsinthevacuumsystemand
replaceit.
3. Tool takes more than two strokes under ideal con di tions to set rivet
and break mandrel:
CAUSE:Lowairpressure.
REMEDY: IncreaseairpressurebutdoNOTexceed7bar(100PSI)
attool.
CAUSE:LooseNosepieceorimpropersizeofnosepiece.
REMEDY: Tightennosepieceoruserightsize.
CAUSE: Rivetbodytoolongforthethicknessofthejoint.
REMEDY:Therivetbodyshouldbe3-6mmlongerthanthethicknessof
jointonly.

Servicing Procedures...
1. Changing Nosepieces:
Hookupthetooltotheairlineanddepressthelever.Whilecontinuingtohold
theleverdown,usethemaintenancetooltoremovetheunwantednosepiece

2. Cleaning and Changing of the Jaws:
Disconnect the tool from the air line and then remove the head with the
maintenancetool. Holdthejawhousingcouplerfirmlyandremovethejaw
housing. Clean the jaws with either a steel brush or solvent. If excessive
wearisapparent,replacethemwithnewjaws.Beforereassembling,applya
