Slowly rotate the neutral adjust bracket in the opposite direction until the other servo gauge begins to increase
in pressure. Mark the position of the neutral adjust bracket.
Rotate the neutral adjust bracket to a position between the two marks, and hold while torquing the washer head
screw to 95 - 132 In. Lbs.
Stop the prime mover. Remove the gauges and install the gauge port plugs. Install and adjust, if necessary,
the external control linkage.

Start the prime mover and slowly accelerate to normal operating RPM.
Loosen lock nut with 1/2" wrench and slowly rotate the neutral adjustment screw, with 5/32" internal hex
wrench, until the pressure is equal on both servo gauges.
Slowly rotate the neutral adjust screw until one of the servo gauges starts to increase in pressure.
Noting the amount of rotation, slowly rotate the neutral adjust screw in the opposite direction until the other
servo gauge begins to increase in pressure.
Turn the neutral adjust screw back one-half the amount noted above. Hold the neutral adjust screw and torque
the lock nut to 25 - 30 In. Lbs.
Stop the prime mover. Connect the control input. Remove the servo pressure gauges. Return the machine to
normal operating condition. Restart prime mover and assure that hydrostatic system is in neutral.
