4.1.4WarmingUptheSystem
Whenworkinginacoldclimate,itisimportantto:
n Usethepreheatingfunction
n UseISOVG32hydraulicoil
n Opentherecirculationvalvewhenstarting
Thesefunctionspreventpreheatingandtheheatingisstoppedautomatically:
n Drilling
n Rotation
n Tramming
ActivatingCylinderFunctionsduringPreheating
Itisrecommendedtoactivatethecylinderfunctionsincoldclimate.
Condition
p
Preheatingisactive.
1.
Positiontheboomandfeeder.Startrodhandlingandtrackoscillationtoactivatecylin
derfunctions.
è
Activationofcylinderfunctionswarmstheoilinthesystem.
2.
Runrotationforoneminute.
è
Coldoilintherotationcircuitischanged.Rotationpreventspreheatingandthe
heatingisstopped.Preheatingstartsautomaticallyafterrotation.
3.
Heattheoiluntilthetemperatureofthehydraulicoilisabove21°.
AutomaticPreheating
AutomaticpreheatingisactivatedfromthecontrolsystemmenuSettings,Rig.Theactiva
tionissettozerowhenthecontrolsystemisrestartedandneedsreactivation.
Automaticpreheatingwarmsthehydraulicoilwhentheoiltemperaturefallsbelow20º,
min.temperatureforheatinginasituationwhichallowspreheating.Thepreheatingcon
tinuesuntilmax.temperatureforheatingisreached.Afterdrilling,rotation,andtramming
preheatingstartsautomatically.
ManualPreheating
Manualpreheating isactivatedonthepanellocatedbytherighthandlever.
Manualpreheatingisappliedwhenthehydraulicoiltemperatureisbelowmin.tempera
tureforheating.Themodeselectormustbeintrammode,drillmode,orpositioning
mode.
Thepreheatingturnsoffduringdrillingandhighspeedtramming,andneedstobereacti
vatedifrequired.Afterrotationandlowspeedtrammingthepreheatingturnsonautomati
cally.
