I was looking at the 555xp and the 562xp and noticed the smart start feature on these saws . The site says it is for starting the saw with less effort. Is this like the easy start on the stihl saws ? I have looked at the videos on the 555 and 562 on here and on youtube . if some one with these saw can help me out that would be great. Or even a short video of this smart start feature.
