Educate me on the hazards of drawing the tip through the cut. NO, I don't draw the tip through the cut; it really never crossed my mind; but, I don't recall it ever being discussed on AS as hazardous. I am big on safety, so if something is unsafe I want to know. Thanks in advance.
Well especially if the cut is not complete all the way through, you are pulling the bar back out and exposing the "kickback" area of the bar to solid wood.
But also if the cut is complete, depending on the compression forces involved with the way the log is balanced in regards to the natural slope and elevation of the ground, pulling the saw back out if the log closes and the cut pinches the bar tip as you are pulling it back out can be a dangerous situation also.
Throttle control is key here too. A good experienced saw operator should NOT be still full throttle when the saw gets to the end of the cut. If you are pulling the tip back out of the cut off the throttle it is not so bad. But if you are lazy and still have some throttle and have a spinning chain there is a potential for trouble. Just better to not pull the saw tip back out through the cut.
From the video: Random engine revving for no reason while walking around . A sure sign of an idiot wielding a saw.
Also changing saw handling position constantly right to left. Bad news as this means he was uncomfortable and getting tired holding the saw the way he was. Tired and uncomfortable means he is going to doing something stupid. Plus as i mentioned in my earlier post he is, especially in the second part with the second chain, constantly leaning with his unprotected head directly over the chain and not to the side of the saw. Much better to kneel then to lean over the saw like that as you have no chance of avoiding a lethal kickback.
For those who are interested to listen, years ago cutting up a large eucalyptus tree we had felled on a farm. I was bucking it into manageable pieces when the saw (Stihl 066) hit something in the cut and ripped itself out of my grip and went straight up and over my right shoulder and landed over 7 meters behind me. Turns out it was a very old steel fence post that the tree had grown around when it was about 80 years younger. If i has been standing the way this clown was and not kneeling to the side of the saw i would at the very least have been very messed up if not dead. PPE or not.
An idiot with all the PPE in the world will still find a way to kill himself. An experienced and well trained saw operator who respects the tool they are using can work perfectly safely for most things with only gloves, eyes and ears PPE.
