Hello Rod-san,

How are you doing? After modify the HPS, the Y2 actuator(closest to Z3)
squeaky sound has occured(move the actuator round 1Hz),after bring up
the High pressure.
But it has gone,when we did random. (But it happens all the time now) So
I checked both 469D program. These were nothing wrong. I changed Valve
driver, but it was OK.
I wanted to change the ServoValve,but we don't have any spare for that.
Custmer still don't know it happen all the time. 
I really wondered, we modifyed the HPS. It seems getting worth. (It's
about 80gal maximum) Please help!!

Best RGDS,
Yutaka
