Thanks for the video, the computer graphics really spell out the whole risky business and how kickback is an ever present danger. Concentration 100% the whole time you pick up the chainsaw, even be switched on before you approach the jobsite. You have to be in the right frame of mind- no alcohol, no drugs. Total mind on safety, including preplanning a chainsaw job and risk identification. Thanks again, a little thought before you get started with a chainsaw can save a lot of grief later.
