i cant keep any of these blowers running. we have 6 blowers, and 4 of them have had to go in and be warrantied. The crank bearings and seals have gone on every one of them. I was told stihl figured out the metal in the motors werent strong enough or something and have come up with a fix for it. these blowers have spent more time in the shop then anything. the static straps inside the tubes keep coming out of the holders as well. i was amazed by the power of them, but the longevity on these things suck. the rubber caps on the bottom for shock absorption keep popping off as well. anybody else having these issues?
