I have a new chainsaw, a Stihl ms251! Took it for a test drive today and threw everything at it. I was cutting up large tree tops into smaller pieces so I could skid them out with the tractor. Trees were laying on each other, kick backs and pinches waiting to happen on every limb.
It has a chain brake like most saws. Activated by bumping the front guard or letting the automatic inertia brake work. Both worked very well. At one point, when I could do it safely, I let the saw kickback, brake worked!
It’s sort of neat how the choke turns off automatically when the throttle is pressed. I really like that feature compared to the old saw. The balance is good, handles well. I had a big limb kickback and knock the chain off, quick and easy to put back on and tighten. So I’ve had my oops moment...
I also cut a big pine over 24in in diameter. There was pressure on the cut, trying to pinch the bar. I easily widened the cut only the width of the bar, it cut straight and true.
And fuel, lite on gas. It’s supposed to get 20% better fuel economy than the model it replaced. I ran it for about 1/2 hour, only used a half tank of gas.
The engine actually has a break in period. They recommend not running at full throttle until the 3rd tank of gas. So I still don’t know how it’ll cut at full throttle. 2/3 throttle was impressive, can’t wait! It cut like a dream compared to the old husqvarna.
I’m a happy camper!! Now if the old saw can be fixed cheaply I’ll have a backup saw too.
