The chainsaw arrived today and at first I thought it was a dud, because it would not start when I inserted the battery, pushed the lockout button and pulled the trigger as I do with all my other hand held electric tools. The manual's instructions seemed to indicate that was the way to start it, but I then noticed something else in the descriptive figure and on the chainsaw itself. In addition to the lockout button and the trigger switch, there is also an On/Off switch, which powers the unit on digitally and must be switched on for the unit to operate. It works like a spring loaded toggle, push and release to turn on, then push and release again to turn off. When the saw is turned on, a green light illuminates and there are four quick beeps to indicated that the unit is ready for use. If the chain brake is pushed forward, a red light will also appear and there will be a continuous series of warning beeps. There are many other beep and red light sequences for various faults, such as overheated battery and an overload condition. In most cases, the saw will auto power down to prevent damage, so even if you don't release the trigger damage will be averted. So, basically there are three separate switch circuits: On/Off, inertia chain brake, and trigger.
Overall construction seems a lot more solid than my other electric chain saws. The bucking teeth are steel, instead of a plastic case molding and all the fasteners are star (Torx) head. It weighs nearly 12 lbs with the battery installed, which is about 2-1/2 lbs more than my other Greenworks 40V Li-Ion chainsaw with a 14" bar and chain. It runs at a much higher speed too, and comes equipped with a genuine Oregon sprocket tip bar and chain, instead of the no-name skip tooth chain on my other electric saws. Then auto chain oiler has a nice tether on the cap to avoid loss and seems to works well. The saw includes not only the usual plastic scabbard, but also a nice two-piece soft carry case, with a separate velcro scabbard piece that can be removed if the plastic scabbard is being used, although it will fit over it if need be.
