The wafersaw will down until Jan 3, 2007. The spindle assembly will
have to be replaced. Parts and field service will not be available
until 12/18. As a reminder, the spindle MUST not be touched unless the
air to the system is ON. The spindle shaft and motor has very close
tolerances, the high pressure air serves as an air bearing to prevent
parts from making contact. So, when shutting down the system, shutting
off the air needs to be the very, very LAST step.
