3. Jaw Opening Adjustment:
Toobtainthemaximumstrokeofthetool,properdistancesettingbetween
thejawhousingandtheheadisveryimportant.Firstloosenthelocknut.
A rivet is then inserted into the nosepiece which should be selected to
matchtherivetsizetobeset.Whilescrewingorunscrewingthe head to
achievetheminimum opening of thejaws,checkif therivetmandrelcan
beremovedandinsertedfreely.Fastenthelocknutaftertheadjustment.
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 broken:
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 conditions 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.
Ifmalfunctionpersists,callanauthorizedSunexTools®warrantycenter.
Air Supply...
Toolsofthisclassoperateonawiderangeofairpressures.Itisrecommended
thatairpressureofthesetoolsmeasures90psiatthetoolwhilerunningfree.
Higher pressure (over 90 psi; 6.2 bar) raises performance beyond the rated
capacity of the tool which will shorten tool life because of faster wear and
couldcauseinjury.
Alwaysuse clean,dryair. Dust,corrosivefumes and/orwaterintheairline
willcausedamagetothetool.Draintheairtankdaily.Cleantheairinletfilter
screenonatleastaweeklyschedule.Therecommendedhookupprocedurecan
beviewedinabovefigure.
The air inlet used for connecting air supply has standard 1/4" NPT. Line
pressureshouldbeincreasedtocompensateforunusuallylongairhoses(over
25feet).Minimumhosediametershouldbe3/8"I.D.andfittingsshouldhave
thesameinsidedimensionsandbetightlysecured.
Lubrication...
Lubricatetheairtoolwithqualityairtooloil.Ifnoairlineoilerisused,run1/2
ounceofairtooloilthroughthetoolbysquirtingoilintothetool'sairinletor
intothenearestconnectiontotheairinlet,reconnectingairsupply,andthen
runningtool.Donotusemorethan1/2ounceofoil,asoverfillingwillreduce
theperformanceofthetool.
Operation...
When the Lever/Trigger is depressed, the throttle valve is moved down off
its seat by the valve tube.Air enters the bottom of the air cylinder, forcing
thepistonassemblyup.Asthepistonassemblyrises,theplungerrodforces
hydraulic fluid in to the upper part of the hydraulic section, retracting the
hydraulicplunger. Meanwhile,thejawsgripthemandreloftherivet,pulling
untiltherivetissetandbreakingthemandrelintheprocess.
Whentheleverisreleased,thethrottlevalveresetsandshutsofftheairsupply.
Thevalvetubespringthenliftsthevalvetubeandexhauststheairthroughout
thehollowofthevalvetube.Thereturnspringreturnsthehydraulicplungerto
itsoriginalposition.Thisopensthejaws,releasesthemandrel,andretractsthe
pistonassemblybacktoitsoriginalstaticsite.
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
andtightenthenewnosepieceinplaceagain.Whentheleverisreleasedand
thetoolisatrest,acircularopeningshouldbevisiblewhenlookingthrough
thehydraulicsectionfromtherearglandtothe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
thincoatofoiltotheslidingsurfaceofthejaws.Reassemblethetoolinthe
reverseorderwhilemakingsurethatthechamferedendofthejawpusheris
incontactwiththejawsproperly.
