

5.1AdjustmentofRotationSpeed(foragriculturalapplications)



Turningtheregulationscrewtotherightwilllowertherotationspeed



Option:

Ifa“K”isstampedinthespeedregulationscrew,thesprinklercanbestopped

completelybyturningthespeedregulationscrewtotheright(fromyearof



Byturningtheregulationscrewtothelefttherotationspeedisincreased.



Forminimalspeed,theuseofclearwaterisrequired.

5.4 Winterproof



Duringthefrostperiodpleasetakecare,thatthereisnowaterstandinginthe

sprinkler.Remainingwaterinthepistondrivedoesnotcausefrostdamages.Isthe

sprinklerputagainintooperation,althoughinthepistonareaisstillice,itwilltake

about15minutestodefrostthedrive,whentheicetemperatureisapprox.–20°C.



5.5 Puttingintoserviceinspring



Thesprinklingheadofthepistondrivesprinkleris,duetotheloadalterationsand

thedifferentinstallationconditions(humid,dry),exposedtoextremetensions.

Undertheseconditionsthepistoncangetaxialplay.Inordertoavoidinterruptions

ofservice,thepistoncovershouldbetightenedupattheputtingintoservicein

springduringitsfirstandsecondyearofoperationasdescribedbelow.



Thecoverhastobetightenedupwith

thefacespannerZB98236andan

effortofapprox.10Nm.Thismeansat

aleverlengthof10cmyouhaveto

mobilizeastrengthof100Nonthe

spanner.



Note:

Afterthe3rdand4thwinterthere

shouldn’tbeanymoreexpansions.

 

Option:

Beforetighteningupthegreycover,

thesafetyscrewhastoberemoved.

Aftertheadjustingofthegreycover,

thesafetyscrewhastobescrewedin

again.



Thesafetyscrewpreventsan

independentlooseningofthegrey

cover.
