Well done Scott.
My 922 is the only one I ever put a guage on & I set the press to 15bar (210psi).
The older two hoes, the press could have been higher, I had an amp meter wired in thru the plug... cyls moving - 1.1, no movement - 2.1amp.
Your due dillengence has paid off & benifited all of us. Thank you.
