<High-pressure Safety Valve Adjustment Procedure>

[1] Referring to the enlarged view of the high-pressure safety valve shown below, loosen the lock nut. (M10

lock nut, Width across flats: 14 mm)

[2] According to the pressure adjusting screw length reference chart, determine the screw length

corresponding to a desired control pressure setting.

* Tip of adjusting screw: Hexagon socket head, Width across flats: 5 mm

* One turn of the adjusting screw changes the pressure by approx. 7.7 MPa.

[3] Turn ON the hydraulic unit power supply, and select

the setting mode through panel key operation. Then,

set a desired pressure.

[4] Select [n05] (rpm display) in the monitor mode

through panel key operation to show the current rpm.

[5] Adjust the pressure adjusting screw length in the

longitudinal direction, and find an activation starting

point as shown on the right.

[6] Turn the pressure adjusting screw clockwise by 1/8

turn from the activation starting point to tighten the

screw.

[7] Tighten the lock nut. This completes the safety valve adjusting procedure.

(When tightening the lock nut, be careful not to allow the adjusting screw to turn.)
