We recently bough a used Okuma LB15 with Tail stroke with OSP 5000L . The machine was supplied with a Collete we wish to replace it with new hydraulic chuck.

But the spindle is not getting locked. We tried to use m19 command even with C
M19C0 / M19C270

But getting Alert 472 of Spindle

We tried to check it in manual but no luck can any one suggest any other way we can lock the spindle so that we can at least change it to chuck.

This is first time I am using Okuma OSP
