6. Rotate the neutral adjusting screw clockwise until the pressure increases on the gauge.
Note the angular position of the wrench.
7. Rotate the neutral adjusting screw counterclockwise until the pressure increases by an equal amount
on the other gauge.
Note the angular position of the wrench.
8. Rotate the neutral adjusting screw clockwise half the distance between the wrench positions noted
above.
The gauges should read the same pressure, indicating that the control is in its neutral position.
9. Hold the neutral adjusting screw stationary and tighten the locknut (D060). Torque to 10 N•m [9
lbf•ft].
