1.Overview
(1) The availability of subassemblies and components, repair parts, specialized tools, and maintenance
manualsdoesnotimplyqualificationtoassembleand/orservicescubaequipment.Improperserviceofdive
equipmentcanleadtosevereinjuryordeath.DiveGearExpressrecommendsthatnonqualifiedindividuals
seekprofessionaltraining/mentoringbeforeattemptingrepairsorservicingonanydivingequipment
Failuretofollowtheproceduresoutlinedhereinmayresultininjuryordeath!
(2)Inthefollowingpageswillbefound,thedisassembly,assembly,tuning,andtroubleshootingstepsfor
thesecomponents.Photosareusedthroughouttoillustratetheprocedures.
Pleasepayspecialattentiontoallcautionnotes!
(3)Wheneveranitemofextraimportanceneedstobeobserved,a“CautionNote:”willappear,followedby
therequiredinformation.Seebelow.
CautionNote:Thismustbereadandfollowed!
(4) Included in this manual is a list of recommended/required tools for each disassembly, assembly, and
testingsection.Theyareidentifiedineachsectionwheretheyareused.
(5) Schematics are located inthe rear of this manual. The drawings containthe detailed parts lists. The
drawingsalsoincludethetorquespecificationsforpartswhererequired.
(6)Ageneraltroubleshootingguidewithspacefornotesisalsoincludedforthoseusingaprintedversion.
Thosewhopreferanelectronicversionshouldkeepdetailednotesinanaccessiblelocationfortheirown
observationsandservicetips,aswellasarecordofservice.
(7)Throughoutthetext,partsarereferencedusingtheitemnumberontheschematictofacilitatelocating
eachindividualcomponent
(8)Photographsofthepartskitsareshowntoillustratethateachcomponentisindividuallybagged.Parts
shouldnotbetakenoutoftheirpackaginguntiltheactualassemblystageisreached,andtheuserisready
tolubricate,wherenecessary,andinstallthem.
(9) Ensure the service area is free of any environmental concerns that may cause problems during the
servicing of your regulators. The area must be clean and organized. The use of nitrile gloves is highly
recommendedforthefinalrinsingandassemblystages.Thiswillminimizetheriskofskinoils,contaminating
theinternalcomponentsoftheregulator.
(10)Ensurethatallrequiredservicing/testingairsuppliesareavailableandatthepropertestpressures,if
not using a regulated supply from a single source. This would include the use of cylinders of compressed
breathing air from an OCA grade source if you wish to maintain the oxygenclean status of the unit.
CautionNote:Onlyuseairfromabreathingairsource!
 

CleaningandRinsingGeneralConsiderations

(11)Cleaningandrinsingofthecomponentsshouldbedoneusingclean,freshwater.Ifavailable,distilled
waterisrecommendedtomaintainoxygencleanliness.
(12) Only use degreasers that leave no organic residue (clear Simple Green, dyefree Dawn dishwashing
liquid,orBlueGoldCleanerasexamples).
(13)Todealwithcorrosion,usea50/50vinegarwatersolutionandnylonbrushes.
(14)Allowpartstoairdrywithouttheuseofclothsthatmayleavefibers.Forregulatorsthataregoingtobe
used with Oxygen percentages above 40%, a UV light is strongly recommended to check for organic
contamination.
(15)Onceallserviceprocedureshavebeencompletedandbenchtestingdone,inwatertestinginaconfined
environment such as a swimming pool is recommended to confirm proper function before taking the
regulatoronanactualdive.
CleaningofRegulatorParts
(16)CleaningCleaningofthepartsthataregoingtobereusedisoneofthemostcriticalstepsinservicing
theregulator.Aswasstatedearlier,usethepropersolutionsforthejobathand.Vinegarandwaterarenot
asusefulforremovinglubricatinggreaseasoneofthedetergentsthatwerenoted.Bythesametoken,
thosedetergentsarenotasefficientasthevinegar/watermixindealingwithcorrosivebuildup.
(17)Therefore,whereyouhaveabuildupofcorrosion,youmayalsohavelubricantonthesurfaceofthe
part.Beforedealingwiththecorrosion,usehotsoapywaterandasoftbrushtoremovethelubricant.Then
usetheacidicsolutiontodealwiththecorrosion.
(18)Oncethecorrosionhasbeendealtwith,washthepartsusingafreshsoapandwatersolutionwhile
wearingnitrileglovestoreducetheriskofcontaminatingthepartswithskinoils.Rinsethepartswithclean
runningwater,distilledispreferred,thatisallowedtodrainfreely.Aplasticpastacolanderavailableatany
storeisexcellentforthis.Forverysmallparts,ameshstrainerforsinkdrainsworkswell.Oftensoldasa
set,theyareinexpensiveandcanbeusedformanytypesofregulatorcomponents.Seethephotographsof
eachinthetoolsection.
(19)Afterwashingandrinsingtheregulatorparts,allowthemtoairdry.Usingadryingrackwillaidinthis,
aswellashavingtheairintheroomcirculating.Donotlaythepartsonapaperorclothtowel.Doingsoruns
theriskofhavingfiberssticktothemthatwillcauseissueswithsealing.Inadditiontothis,fiberscanbea
hazardwhenusingtheregulatorwithhighoxygencontentmixes.
(20)Oncethepartshavedriedcompletely,laythemoutinorderofassemblyonthepadusedonthework
surface.Makingsurethatithasbeencleanedandisfreeofcontaminants.Arubberorsiliconematofsuitable
sizeworkswellforthis.Youcanalsousesmallcleancontainerstokeepthepartsorganized.Oncetheparts
have beencleanedand dried,theyneed to beinspected beforestarting theassemblyprocess.Thisis to
ensure that no damage or defects exist that were hidden by corrosion, residual lubrication, or other
contaminantsthathavenowbeenremoved.
 

InspectionAfterCleaning
(21)Beforeassemblingtheregulator,itisnecessaryto inspectallofthecleaned components. Usingthe
magnifyingglass,checkallthecomponentsfordamagethatmayhavebeenhiddenbycorrosionorlubricant.
Lookforscratchesthatmayaffectthesealingoftheregulator.Inadarkenedroom,usetheUVlighttolook
fororganicmaterial.Itwillshowupasglowinglinesorfragments.Ifanyarepresent,thepartneedstobere
cleanedanddried!Thisiscriticalforusewithoxygenpercentagesabove50%!
(22)Anotherwaytocheckforresiduallubricantsistofillatraywithclean,fresh,waterdeepenoughtocover
thepartsbyaninchorso.Laythecomponentsinthewaterandcirculatethewateraroundthem.Allowthe
piecestosoakforseveralminutesandthewatertosettle.Onceithassettled,lookforarainbowsheenon
thesurfaceofthewater.Anyresiduallubricantswillfloatandforma“slick”onthesurface.Ifoneispresent,
thepartsmustbecleanedagain.
(23)Nowthatallpartshavebeencleanedandchecked,theassemblycanbegin.Makesurealloldpartsthat
aretobereplacedhavebeendiscardedorsegregated.Removethenewpartsfromtheservicekitbagand
laythemoutintheordertheywillbeused.Donottakethenewpartsoutofthebagsyet!
CautionNote:
Removingpartsfromtheirindividualbags,beforetheyaretobeused,runstheriskof
mixingthemup.Someoringsareverycloseinsizebutarenotinterchangeable!Keep
thepartsinthebagsuntilyouactuallyneedthem.

(24)Aswiththepartsthathavebeencleaned,itisagoodideatoinspectthenewpartsaswell.Especially
theHPseat.Makesureitisfreeofanydefects.Checkalloftheoringsandinspectthemasyouusethemfor
nicksorotherconcerns.Inspectthewasherstoensuretheyarefreeofexcessburrsorotherconcernsthat
couldaffecttheirfunction.Itisalsoagoodideatousethepartslistontheschematictoensurethatallofthe
newpartsthatareneededarepresentandaccountedforintheirrequiredquantities.

(25)LubricationofOrings;Lubricationcanbeoverdone.Doingsorunstheriskoftrappingexcessdirtor
debrisontheparts.Onewayofreducingtheriskofoverdoingitistousethelubeinabagmethod.This
involvesusingasmallcleanplasticbagandputtingasmallamountoflubeinit.Thentheoringisinserted
intothebag,workedaround,excesssqueezedoff,andtakenoutofthebag,andusedinitslocation.

Fig.1Fig.2
 

(26)AnotherwayistoapplyasmallamountofTribolubetotheglovedindexfingerandmassagetheoring
betweenthethumbandindexfinger.Eitherwayworks,butthebagmethodtendstogivebetterdistribution
resultsanduseslesslubricant.

(27)Undermostcircumstances,alubricantisusedcorrectlyverysparinglyornotatall.Innearlyallscuba
applications, ifyoucan see thelubricant, you’ve usedtoomuch. Before using any lubricant, any existing
lubricationshouldberemovedbeforenewisapplied.Indynamicapplications,itisusedtoreduceexcessive
wear.Staticoringsdonotgenerallyrequiretheuseoflubricant.
(28)Wherepartsarenotnecessarytobelubricated,itisgoodpracticetoavoidgettinganylubricantonthem.
PrimarilywhentheregulatorisusedwithhighO2contentmixes.Italsohelpstokeepthosepartscleanand
freeofdebristhatwillclingtothelubricant.

(29)Maintainingoxygencleanconditionsfor2ndstagesistechnicallynotmandatory.The2ndstageisalow
pressuredeviceoperatingat135psi.Regardless,bestpracticeistomaintainoxygencleanconditionsalong
withtheexclusiveuseofoxygencompatiblelubricantswhenservicingtheregulator.
