Leave a comment

We picked this up several years ago. Modern Stihl and Husqvarna equivalents are out of my price range. But for $30 this was a great find. I have the owners manual and parts manual below. The power head is based on the Homelite XL-12, specs below

Stihl 034AV in front of some of the trees we cut down today
