I love it! The worlds largest tree company's Forman's manual states that chainsaws shall not be operated with one hand. I want to point out that the word they use is shall not should.
OSHA also agrees with that company they state, Keep your hands on the saw's handles, and maintain secure footing while operating the saw. Note that it says hands, not hand.
Silly me for having concerns about someone with limited training and experience, operating a saw with one hand.
Thanks for quoting the fat-assed bureaucrats for us but, pardon me, what am I supposed to hold on to the tree with, my tail. or should I just learn to levitate? Ever been 60 feet up on a windy day? You got one thing right, "SIlly me."
