Some additional observations:
1) The saw will auto power off after approximately one minute of inactivity to prevent discharging the battery. The saw can be manually powered off at any time by depressing and releasing the On/Off button, but it is unnecessary to do so when work is done, since it will do so automatically after timing out. The power switch is a continually open circuit, which is closed momentarily when depressed, and all actual switching is done electronically by the digital control unit. :thumbsup:
2) The manual is poorly written, confusing and full of contradictions, omissions and errors. Which is to say, it's your typical Greenworks manual. The instructions for starting the saw were obviously written by someone who has never seen or used the saw, and almost had me calling customer support to figure out why the saw wouldn't start up at first when I tried to follow the manual's instructions. There is no mention in the manual of the operation of the On/Off switch or the auto power off feature. :confused2:
3) in addition to the usual Greenworks 4 year warranty on the tool and 2 year warranty on the Li-Ion battery, there is also a 10 year or lifetime to original owner warranty on the brushless motor. There isn't much that can wear out on a brushless motor other than bearings/bushings and rotor wire insulation, and no doubt other components will wear out and fail long before the motor does. :thumbsup:
4) The stock chain and bar are 0.043" gauge instead of the more normal 0.050" gauge, so it will be interesting to see how this might impact cutting efficiency and durability. It also means I won't using the spare 16" 0.050" gauge chain I have sitting in my parts bin. :frown:
