This dryer is intended for professional and consumer use. This dryer has a polarized plug (one blade is wider than the other). As a safety feature, this plug will fit into a polarized outlet only one way. If the plug does not fit securely, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature. The dryer is virtually maintenance-free. No lubrication is needed. Unplug the dryer from the power source prior to any maintenance. Keep all vents and openings clear of dirt and dust. The exterior of the dryer should be wiped clean with a damp cloth only. The air filter cover, at the rear of the dryer, should be removed and the area cleaned of any hair or dust. There is an air filter underneath the air filter cover that should also be washed and cleaned every couple of weeks so hair doesn¿t catch in the fan. To keep the dryer clean, unplug the dryer from the power source, remove the mesh filter, and wash the mesh filter with soap and water every 30 days. If overheating occurs, an automatic safety device will trip off and the cool air will come out of the dryer for a period of time. Then the hot air will come out again after the automatic safety device resets itself. If this occurs, unplug the cord and allow the dryer to cool for 10 to 15 minutes. Make sure the air vents and removable mesh filter are fully cleaned before starting again.
