[2] Pressure adjustment of main relief valve
1. Attach a pressure gauge to the pressure detection port.
2. Run the pump at its rated revolution speed.
3. Allow the control valve spool to move to its full stroke and read the
pressure gauge value.
4. Loosen the lock nut (2) of main relief valve.
5. While watching the pressure gauge, turn set screw (1) to adjust the
pressure.
・
Clockwise direction (turning rightward): To raise the set
pressure.
・
Counterclockwise direction (turning leftward):
To lower the set pressure.
6. After completing the pressure adjustment, tighten the lock nut (2)
while preventing the set screw (1) from turning.
7. Run the pump again at its rated revolution speed to ensure that the
pressure is stabilized.
