SafetyGuidelines
Thefollowinggeneralguidelines,togetherwiththeinstructionsprovidedthroughoutthisuserguide,
ensureusersafetywhileoperatingandmaintainingtheBalcoWaterJet.If the system is not operated
as specified, the user's safety may be compromised.
• InstallationandremovaloftheBalcoWaterJetsystemshouldonlybedonebyqualifiedStratasys
servicepersonnel.
• Serviceoperationsshouldbeperformedonlybypersonnelwhohavebeeninstructedinrelevantsafety
precautions.
• AllpersonneloperatingormaintainingtheBalcoWaterJetshouldknowthelocationoffirstaidand
emergencyequipmentandhowtouseit.Never block access to this equipment.
• Readandfollowsafetyandmaintenanceinstructionsthatcomewiththepressurepump.
• Donot directthepressurizedstreamofwateratpeople,animals,orobjects.
• ChecktheWaterJethosesbeforeeachcleaningsession.DonotoperatetheWaterJetifahoseis
damagedorcrimped.
• NeveroperatetheWaterJetwhilethecabinetcoverisopen.
• Wearearplugsforprotectionagainstloudnoise.
• ThepowercableshouldbeconnectedataneasilyaccessibleelectricsocketneartheWaterJet.
• Neverconnectthepowerplugtoanoutletthatdoesnothaveaground(earth)wire,andnever
disconnecttheground.Doingsomayexposetheoperatortoseriousdangerfromelectricshock.
• Thewalloutletmustbeprotectedbyaresidualcurrentdevice(RCD).
• Protectelectricalconnectionsfromcontactwithwatersprayandmoisture.
• Neverinsertscrewdrivers,wires,orotherobjectsintothepumporpowersupplyhousing.
• SeveralpartsoftheWaterJetcanremainextremelyhotevenafterithasstoppedoperating.Avoid
touchingthemainpowersupply,thewipermotor,thepressurepumpandthelampsuntiltheyhave
cooled.
• Notifyco-workersandthosewhohaveaccesstotheBalcoWaterJetsystembeforebeginningnon-

FirstAidforWorkingWithPrintingMaterials
Ingeneral,trytoavoiddirectcontactwithuncuredprintingmaterial.Ifskinoreyescomeintocontactwith
it,washtheareaimmediatelyandthoroughlywithwater,andfollowthefirst-aidinstructionsbelow.
ContactwithSkin
Ifuncuredprintingmaterialcomesincontactwithskin:
• Immediatelywashtheaffectedareathoroughlywithsoapandcoolwater,thenremovecontaminated
clothing.Payparticularattentiontoflushingthehair,ears,noseandotherpartsofthebodythatarenot
easilycleaned.
• Usecoolwatertopreventskinporesfromopening,sothattheliquidmaterialdoesnoteasilypenetrate
theskin.
• Donotusesolventstocleanskin.
• Iflargeareasofskinhavebeenexposed,orifprolongedcontactresultsinblisters,seekmedical
attention.Inanycase,ifirritationpersists,seekmedicalattention.
• Avoidtheaccidentaltransferofprintingmaterialfromthehandstootherareasofthebody,especially
totheeyes.
• Ifprotectivecreamwasused,donotreapplyituntiltheskinhasbeencompletelycleansed.
ContactwithEyes
Ifuncuredprintingmaterialcomesincontactwiththeeyes:
• Flushimmediatelywithlargeamountsofwaterfor15minutesandseekmedicalattention.
• Avoidsunlight,fluorescentlight,andothersourcesofultravioletradiation.
Thewearingofcontactlenseswhenhandlingliquidprintingmaterialsisnotrecommended.Iftheliquid
splashesintotheeyeswhencontactlensesareworn,immediatelyremovethelensesandflushtheeyes
withwater.
• Immediatelyremovethelensesandflushtheeyeswithwater.
• Cleananddisinfectthecontaminatedlenses.
• Donotwearcontactlensesuntileyeirritationdisappears.
Ingestion
Ifprintingmaterialisswallowed,refertotheinstructionsincludedwiththecartridge.Seek medical
attention immediately.

Balco WaterJet Safety

Inhalation
Vaporsfromprintingmaterialscanbeirritatingtotherespiratorysystem.Ifrespiratoryirritationoccurs:
• Exposethevictimtofreshairimmediately.
• Seekmedicalattentionimmediately.
• Keepthepatientwarmbutnothot.
• Neverfeedanythingbymouthtoanunconsciousperson.
• Oxygenshouldbeadministeredbyauthorizedpersonnelonly.
• Ifthevictimhasstoppedbreathing,performartificialrespirationorcardiopulmonaryresuscitation.
WasteDisposal
Fullycuredmodelspresentnospecialsafetyorhealth-relatedissues.However,checkiflocalregulations
regardcuredandpartiallycuredresinsashazardousindustrialwaste,andcomplywithallapplicable
regulationsgoverningtheirdisposal.

Balco WaterJet Cleaning Models

CleaningModels
CleaningProcess
Thecleaningprocessconsistsofdifferentmethods,dependingonthesizeofthemodel,howdelicateit
is,andtheamountandlocationofthesupportmaterial.
Usethefollowingmethodsforfinishingthemodelsyouarehandling.
RemovingExcessSupportMaterialbyHand
Whilewearingprotectivegloves,breakawaytheexcesssupportmaterialontheoutsideofthemodel.For
delicatemodels,useatoothpick,pinorsmallbrushafterdippingthemodelinwater.
RemovingSupportMaterialwiththeWaterJet
Formostmodels,themostefficientwaytoremovesupportmaterialisbyusingthehighwaterpressure,
usingthejetorspraynozzles.
JetNozzle
Usethejetnozzlelikeascalpeltocutandtrimlargesupport-structureareas.Thejetnozzleprovides
higherwaterpressureandissuitablefor—
• largemodelswithoutthinwallsorfragilesections
• clearingsupportmaterialfromcavities,pipes,tubesandcylinders
Note:
Thejetnozzleisnotsuitableforcleaningmodelsmadefromflexiblematerials(suchas
Tango™andAgilus30™)andtheirdigitalmaterials.Usingitcouldleavenoticeable
marksonthemodel.
Examplesofmodelssuitableforcleaningwiththejetnozzleare:engineblocksandshoesoles.
