If it does have backstroke blade lift, I can't call it either way from the pics, it's mechanical not hydraulic. Sure way to tell, crank it a couple strokes and watch the blade carefully.
It would be a much nicer machine with fluid cooling & chip washing, but I wouldn't kick it off a job for the want of those features.
Only drawback to those machines today is the price blades are going for on ePay and other places.
