1. Remove cap (N0120).
Removing the cap destroys the caps locking mechanism. Replace with a new cap.
2. Using a 6 mm internal hex wrench, hold adjusting screw (N0010) in place.
3. Using a 19 mm hex wrench, loosen seal locknut (N0020).
4. Turn adjusting screw clockwise to increase minimum displacement or counterclockwise to decrease
minimum displacement.
Minimum displacement is inversely related to maximum shaft speed. To increase maximum speed,
decrease minimum displacement. Adjusting displacement limits also affects output torque. Refer to
the table below for displacement change per turn.
