I found that due to it's light weight, when using my MS170 I was doing things I'd never try with my MS261 or MS461. I made the conscious decision to NOT do them any more!REMINDER EVERYONE, STAY SAFE BY PAYING ATTENTION! I'll share a moment's stupidity and a near miss. Not even a scratch but only sheer luck.
I just ran a tank through the Makita 4300, 15" bar. Remember, small but powerful saws with shortish bars will kick back quickly.
I was bucking up a pile of long limbs mostly 5-10" diameter stuff but a few short bits just a couple of inches too. Remember with a pile of logs things can move around, pinch the saw or touch the tip.. smaller stuff moves easily. I had full chisel chain on, remember it can be grabby on small stuff. Okay I was taking care and doing ok then it started to rain. I had a quarter of a tank left and started rushing just to get it used up and get in out the rain...I let haste take over and care and attention left the building. Cutting a small piece of 2" diameter branch in half I made a really stupid move, let go of the rear handle completely to grab the next log as things moved a bit. I guess I thought the saw was already through the cut but it wasn't and although off the trigger the chain was still spinning and I had no control of the saw. Thankfully I did have a good hold of the front handle and my left arm was taught because the little log moved, the chain bit and grabbed and quick asa flash the saw kicked hard! With my left arm taught it couldn't move toward me but did fly up rotating rapidly in my left hand. Inertia chain brake worked to stop the chain and thankfully I got enough control of the saw in my left hand to stop the saw's rotation with the bar a couple inches from my elbow. So no harm done and after cursing my stupidity and thanking Makita for making a good inertial chain brake, I more carefully readied the last half dozen logs and cut a few more before the saw ran out of fuel.
So several errors, mainly rushing and lack of mindfulness with the saw (most unlike me!), And doing that when cutting up small loose logs in a messy pile was really asking for trouble. I was lucky, got reminded to pay more ATTENTION. I'm sharing as we probably all do stupid things occasionally and a reminder of what can happen is a good learning opportunity! Stay safe gents.
Regarding the chains... the safety chains come into their own when cutting the small stuff. My son put a Rapid Super Stihl chain on a saw prior to cutting up limbs. While it could cut faster on the 4" limbs it would also grab and whip the small stuff around. I suggested he run a green safety chains on the saw for the small stuff and he found it was a lot safer while not noticing any real difference in cutting speed because the stuff was all relatively small.
Glad you survived the experience unscathed!
