1-2. IMPORTANT SAFETY INFORMATION
Toavoidriskofre,electricshock,seriousinjury,ordeathwhenusingyourdryer,followthesebasicprecautions:
1. Readallinstructionsbeforeusingthedryer.
2. InstalldryeraccordingtoInstallationInstructions.RefertotheGroundingInstructionsintheInstallationInstructions
forpropergroundingofthedryer.
3. Donotdryarticlesthathavebeencleanedin,washedin,soakedin,orspottedwithgasoline,drycleaningsolvents,or
otherammableorexplosivesubstances.Vaporscouldigniteorexplode.
4. Donotusethedryertodryclotheswhichhavetracesofanyammablesubstance,suchasvegetableoil,cookingoil,
machineoil,ammablechemicals,thinner,etc.,oranythingcontainingwaxorchemicals,suchasmopsandcleaning
cloths.Flammablesubstancesmaycausethefabrictocatchrebyitself.
5. Donotstoreorusegasolineorotherammablevaporsandliquidsnearthisoranyotherappliance.
6. Donotallowchildrentoplayonorindryer.Closesupervisionofchildrenisnecessarywhenthedryerisusednear
children,asafetyruleforallappliances.
7. Beforethedryerisremovedforserviceorisdiscarded,removedoorstodryingcompartment.
8. Donotreachintothedryerifcylinderisrotating.
