Your appliances are virtually maintenance free. No lubrication is required. Keep heated parts & surfaces cleaned and free from dust, dirt and chemicals (such as hairspray). If cleaning becomes necessary, remember to disconnect the appliance from the power supply and allow to cool. Then wipe the exterior with a damp (never wet) cloth. Do not use any thinner, gasoline, alcohol or like chemicals to clean the tools. If the cord becomes twisted or tangled, untwist or untangle it before use.
WARNING: If any malfunction occurs, DO NOT attempt to repair by yourself as there is no user-serviceable parts.
