ROTATION MOTION CONTROL VALVE ADJUSTMENT

Adjusting the Rotation Motion Control Valve

1. Adjust the supply pressure to the motion control valve to 2700 PSI.

2. Install gauges rated for at least 3000 PSI into the motion control manifold GA and GB ports.

3. Turn the crossover relief valve adjusting screws clockwise (in) to the maximum setting,

while recording the number of turns, so they can be returned to their original settings.

4. Adjust the counter-balance valves with the attachment stalled on the ground until each side

is adjusted to 2500 PSI. You will need to reverse the rotate direction with the attachment

stalled on the ground to adjust the valves independently of each other.

5. Turn the crossover relief valve adjusting screws counter-clockwise (out) to their original

settings. Again, stall the shear in each direction to verify the screws have returned to their

original 2200 PSI setting. If they have not, adjust to 2200 PSI.

6. Reduce the rotation valve input pressure as indicated on page 42
