REASSEMBLY
1. Onceclean,applyaliberalamount
of Dow 33 or equivalent grease to
 thetwoO-ringsonthebrassPiston
 asshownin(Fig8-14,)makingsure
 tollthegroovesthattheO-ringssit
in with grease.
2. Placethesecondaryspringintothe
deeper side of the brass piston and insert the assembly into the
 frontoftheRegulator(Fig8-15).
3. Placethesilverpistonintothe3mmnutdriverandthewasheronto
the silver piston with the curved side of the washer facing the head
 ofthepiston(Fig8-16).Inserttheassemblyintothetanksideof
Regulator and screw silver piston into brass piston until snug. DO
 NOTOVERTIGHTENthesilverpiston.Onlytightenuntilturning
silver piston spins brass piston as well.
4. Placelterinltercapandscrewtheassemblyintolterareausing3/32hexwrench(Fig8-17).
5. Insertpin/sealretainerinorientationshownin(Fig8-18)intotanksideofRegulatorensuringoval
slot in the pin/seal retainer is lined up with bottom slot on Regulator.
6. Insertthe3/32”hexwrenchintobottomslotofRegulatorandpushthePin/SealRetainertowards
 frontofRegulatoruntiltheslotontheRegulatorlinesupwiththeslotonthesealretainer(Fig8-19).
7. InsertthePinDepressionRampandSpringbackintothe
bottom of Regulator with the ramp facing toward tank side of
 Regulator(Fig8-20).Therampshouldfallintoplaceeasily
 andifnot,ensuretheslotsontheRegulatorandPin/Seal
Retainer line up on all sides.
4. UseapairofplierstoremovethetankdepressionpinfromthePin/SealRetainerinthetankside
 oftheRegulator.Besuretograbthepinbyitssmallersection,nearthetip.InspectO-ringonthe
 insideofthepinretainerandreplaceifnecessary(Fig8-5).
5. Usea3/32”hexwrenchtounscrewtheLeverRetainingScrew(Fig8-6).TheLeverisunder 
spring pressure, so you may have to push the Lever down slightly to remove the screw. Once the
 screwisremoved,theLeverwillfalloutandthePinDepressionRampwithSpringwillfallfromthe
 bottomoftheRegulator(Fig8-7).
6. Insertthe3/32”hexwrenchintothebottomoftheRegulatorwherethePinDepressionRampwas
 removedfrom.UsethehexwrenchtounseatthePin/SealRetainerbypushingittowardsthetank
 side(rear)oftheRegulator(Fig8-8).Onceunseated,removethehexwrenchandturnthetank 
 sideopeningdowntoallowPin/SealRetainertofallintoyourhand.InspecttheouterO-ringsof 
 thepin/sealretainerfordamageandreplaceifneeded(Fig8-9).
7. Insertthe3mmnutdriverintothetanksideoftheRegulatorontothesilverPiston.Onthe 
 oppositesideoftheRegulator(front),placetheO-ringpickinthesmallholeonthebrasspiston 
 asshownin(Fig8-10)HoldthebrassPistonstationaryandunscrewthesilverPiston.Oncefully
unscrewed, turn the tank opening side down and allow the washer and silver piston to come out
 onthe3mmnutdriverasshownin(Fig8-11).
8. IfthePistonandwasherdon’tfallouteasily,useplierstograbthePistonbytheheadandliftit
from the Regulator body. Then use an O-ring pick to loosen the washer, carefully, while not
 damagingthewasher.Notethewasherissemi-transparentandmaybehardtosee.Ifthewasher
 isdamagedortheRegulatorwashavingoverpressurizationproblemsthewashershouldbe 
