4.4 Adjusting the spray pattern (HB 710 Spray only)
Thespraypatternisalteredbyadjustingthesprayair.
Settheoptimumspraypatternbyturningthespray-airchoke(14)intheprotectivesleeve
(13):
• Turningitclockwisedecreasesthespray-airpressure.
• Turningitanticlockwiseincreasesthespray-airpressure.
4.5 Automatic temperature reduction (ACE)
Unnecessarythermalloadingofthemeltshouldbeavoided.Thedevicethereforeswitch-
estostandbymodeatreducedtemperaturewhenthetriggerhasnotbeenactuatedfora
considerabletime(pausedoperation).
Intheconditionassuppliedthetemperatureisreducedby72°F/40°Cafter30minutes’
pausedoperation.TheprogrammingoftherelevantparametersisdescribedinSection
3.3.2.
BrieyactuatethetriggerortheUporDownbuttontoquitstandbymode.Thedeviceim-
mediatelyreheatstoworkingtemperature.
4.6 Switching off
1. PresstheStart/Stopbutton(6)forapprox.1suntilthedisplaygoesout.
2. Adjusttheoperatingpressuredownto“0”withthepressureregulator(3)ordisconnect
thecompressed-airsupply.
