•Atpressuresbelowtheratedpressureindicatedonthelabel,thenozzlewillhavereducedowand
  reach.Besureyouhaveenoughowandpressureforthesituation(SeeIFSTAand
NFPA manuals for guidelines).
•Atpressuresbelowtheratedpressure,theoscillatingnozzlemaynotoscillate.Obstructionstothe
  owthroughthenozzlewillalsocausethenozzletonotoscillate.
•Notforuseonelectricalres.Maycauseelectrocution.
•EnsurethethreadonthenozzleswivelismatchedtothethreadontheMercuryQuickAttackoutlet.
Do not use thread adapters between the monitor and nozzle.
•Readandfollowthetippressureandowsintheoperatinginstructionsbeforeuse.
• Before operating the oscillating nozzle, make sure the connecting rod in Figure 6 is parallel
  withthewaterway.Failuretodosomaycausetheoscillatingmechanismtobindduringoperation.
• Do not adjust oscillating angle while oscillating.
•Ifanytagsorbandsonthenozzlearewornordamagedandcannotbeeasilyread,they
should be replaced.
•Forusewithfreshwaterorstandardreghtingfoamsonly.Notrecommendedforusewithsaltwater.
  Afterusewithfoamorsaltwater,ushwithfreshwater.
• Do not over tighten the nozzle onto the mating connections.
•Thenozzleisconguredforoptimumperformance.Donotalterinanymanner.
• Your nozzle should be inspected prior to and after each use to ensure it is in good operating condition.
Periodicallyanunanticipatedincidentmayoccurwherethenozzleisusedinamannerthatisinconsistentwithstandard
operating practices from those listed in IFSTA. A partial list of potential misuses follows:
 •Operatingabovemaximumratedpressureandow.
• Not draining and allowing water to freeze inside the nozzle.
• Dropping the nozzle from a height where damage is incurred.
 •Prolongedexposuretotemperaturesabove+130degreesF,orbelow-25degreesF.
• Operating in a corrosive environment.
 •Othermisusethatmightbeuniquetoyourspecicreghtingenvironment.
Therearemany“tell-tale”signsthatindicatenozzlerepairisinordersuchas:
 •Controlsthatareeitherinoperableordifculttooperate.
• Excessive wear.
• Poor discharge performance.
• Water leaks.
Ifanyoftheabovesituationsareencounteredthenozzleshouldbetakenoutofserviceandrepairedandtestedby
qualiednozzletechnicianspriortoplacingthenozzlebackintoservice.

  MercuryQuickAttackasshowninFigure1.
 2. RotatethehandleupwardandoutofthewaytogainaccesstothetoptrunnionasshowninFigure2.
3. Using a 5/8” open end wrench remove the top trunnion and the trunnion on the left side of the
  MercuryQuickAttack.
4. Position the bracket over the trunnion holes as shown in Figure 3.
 5. ApplyLoctite277orequivalenttoeachnewtrunnionprovidedwiththenozzle.Thetrunnionsare

makesurethelockknobisfullyloosenedtoallowthetrunniontobecompletelytightened.
2. Usinga5/8”openendedwrenchremovethebottomtrunnionontherotationjoint.Toaccessthetrunnion
placetheoutletinthefullyraisedposition.

joint.Tightenusinga5/8”openendedwrenchto25ft.-lbs. The longer lower trunnion is required to limit the
lower elevation to 30 degree so the oscillating nozzle cannot be locked at an elevation lower than 30 degrees and left
unattended.
4. Operatethelockingknobtoconfirmtheelevationjointmovementisrestrictedwhenthelocking
knob is tightened.
