1. Run prime mover at 1800 min
-1
(rpm).
2. If using a PWM signal, ensure the signal is off.
3. Check the servo pressure gauges, ensure the differential between M4 and M5 is less than 2.5 bar [36
psi].
4. Using a 3/4 in deep socket, unthread both servo cylinders 2-3 turns.
This step ensures the servo cylinders have no contact with the servo piston.
5. Stroke the pump by turning the control eccentric screw (or supplying current to solenoid C1) until the
servo pressure at port M4 is 1 to 2 bar [14– 29 psi] greater than at port M5 and the system pressure
gauges indicate displacement.
Pressure should be greater at port MA for clockwise rotation, or MB for counterclockwise rotation.
This also indicates the servo piston is in contact with the servo cylinder on side M5.
