Installation Notes

Installation should be performed by a qualified machinist with the lathe fully powered down and spindle locked before mounting or adjusting the tool post holder. Verify that the tool post is BXA-compatible before installing this holder, as fitting an incorrect series holder can result in improper centerline height and unsafe tool engagement. Tighten the quick-change locking handle to the tool post manufacturer's recommended procedure. Confirm blade seating and alignment before taking a test cut.
