I thought there was another picture were they did that and I found it but also discovered this!
Sure enough I prove myself wrong about that long handle rotating up to get it out of the way.
Here it is being used by that handle angled in an upward position and the operator back on that side of the saw.
Maybe that guy just needed to stand up so he could get out of the way and move the handle up to a position where he could get a purchase on it.
Is it the addition of the guide/pressure bar that makes working from this side of the machine practical? I wonder if when they were on the other side of the machine, were they having to pull on it to add extra pressure?
