Problem karlsuss SNF 2004-07-27 19:54:49: Mask Vacuum

[flannery at snf.stanford.edu]

Twice now this machine has turned off the mask vacuum as I am loading a mask. Both times the mask has dropped.  The front panel does not report loss of mask vacuum, just that it is off, as if it turned it off. The vacuum line was not pinched. Both times I chchecked and the mask was being firmly held before I started the load.
Load it at your own risk.
