Leaf Blowers

I have a Husqvarna blower model 125B, purchased online this past April 2013. Over the 15 or so times I have used it this spring and summer, the motor is getting louder and louder, so loud that even with a pair of very effective ear plugs the sound is obnoxiously loud. Is there any way to alleviate this problem? Should I take it to a dealer? Since I purchased it online, would an authorized dealer repair it under warranty?

Thank you.
