1. Loosen the locknut.
2. Rotate the adjusting screw to achieve the desired maximum displacement.
3. Set the adjusting screw against the servo piston by feel before counting turns.
Refer to the table for change per turn. Clockwise rotation decreases displacement, counterclockwise
rotation increases it. Adjustment is possible from zero to maximum.

Control Neutral Adjustment
All functions of the Electric Displacement Control (EDC), are preset at the factory. If necessary, adjust the
pump to neutral with the pump running on a test stand or on the vehicle/machine with the prime mover
operating. If adjustment fails to give satisfactory results, you may need to replace the control or coils. See
Minor repair for details.
