Note1)

 

Size 10 requires at least 0.35 MPa of operating pressure to reach the minimum rotation time (0.03 s/90°). 

Note2)

 

Operate within the speed adjustable range.   

Operation at a low speed outside of the speed adjustable limit may cause stick slip or operation failure. 
It is difficult to make adjustments during use if rotation time is changed to 0.5 s/90
