2. GENERAL INSTRUCTIONS
Beforeconnectingthecontrol boxtothepowersupply,makesurethatthepowersupplyis
compatiblewiththeratingplatevalues.
The control boxmustbeused onlyforthepurposesforwhichithasbeendesigned,i.e.for
controllinganelectromagneticvibrator.Anyotheruseisimproperandthereforehazardous.
The manufacturercannotbeheldresponsibleforanyimproper,incorrectorunreasonableuse.
Intheeventof faultsand/ormalfunctionsof theappliance,switchitoff and donottamperwith
it. Foranyrepairs,contactonlyTUMAC,whichwill useoriginal spareparts.Failuretocomply
withtheseinstructionsmayjeopardisethesafetyoftheappliance.
Anyadjustment, measurementorcheckthatisrequired must becarriedout byauthorised and
qualified personnel.Themanufactureracceptsnoliabilityforharmtopersons,animalsor
thingscaused byinterventionstothecontrolbox byunauthorised andunqualified personnel.
