so far i only use it out back on my horse track to trim back vegitation and trees when no one is around
if i was to use it otherwise i'd shield it, it would be easy to do
with safty glasses and hat there is little danger to the operator as the cutter is some distance away
iv used it 3 times for about 2 days each time with no ill affect
its one of those things that looks more dangerous than it is
i was a tool and die maker for 30 years and in a shop some of the machines that look the most dangerous are in fact the safest, sorta like with this
the way i use it its harmless to me, other aplications maybe would be different and i would use it acordingly
iv never gotten so much as a bruise
anything that has hit me is more a thud than anything else, a screen could be mounted to the fel uprights if needed
