    Need help! hawk150 hydraulic pressure too HIGH!!

    Hi, does anyone have any knowledge of the hydraulic system on a hawk lathe? My lathes pressure gauge popped and was leaking, so I replaced it. When I put the new one in and turned on the machine, I had over well over the normal 40 bar pressure, over 800 PSI coming out of the pump! So, I shut the power off, not to destroy the new gauge. Is there an adjustable regulator or something that could cause my problem? Any advice would be appreciated. Thanks!

    I don't have any alarms
    The lathe has the Acromatic 2100 control

    Precisionatl,
    See attached file: 91203587A-HAWK-ERD_SYS-HYD-PNEU-COOLANT-Diagrams_1-6.pdf (Page#3 lower left)
    There is adjustment on the pump.
