    John on the rear of the power unit just below the motor is the adjustment, Loosen the jam nut and adjust the screw inward about a 1/16th turn at a time to increase pressure. Remember this "will not" increase speed "only" pressure, and increased pressure will cause the motor to operate harder and draw more amps.
    :rolleyes: John...

    :nono: I highly discourage changing the pump relief setting unless you have a pressure gauge to check it with.You can do more harm than good! You'd be much better off driving down to your local plow shop on hydraulic shop and having them set it for you.
