I purchased this Chinese jackhammer of a marketplace for $2500
I rented one from a rental place and it was absolutely useless. Had no power at all. I think the hydraulic flow was a little bit too high for this machine
The SCL 1000 uses 15 gallons per minute
This new jackhammer from marketplace is awesome. I had to do a little customizing to make it fit, but it definitely works now.
