i believe this stihls worst saw ever,lasts about a year,then anti-vibe system brakes and might as well by a new one for the cost to fix all my saws go thru hell everyday,ms200t,310,460,660,the 280 is the only one that does this but stihl says its not there problem???
I think they best handle something 40-50cc as a first saw.
The 170 and 180 feel like children's toys and don't really relate to the kind of saw most arborist/foresters will be using in work.
