When dicing in single cut mode, water didn't come out. Water gun didn't work, too. Looks like water is turned off.

Someone had manually shut off the main water valve.  DON'T DO THAT!

Subject: Problem wafersaw SNF 2010-11-20 12:48:32: Resin blade broken
Message-ID: <mailman.974.1357938994.26017.wafersaw-pcs@snf.stanford.edu>

Resin blades break repeatively during cutting, with either blade holder. Blades are okay for several successful cuts, but break when the cutter head moves over to above the wafer and drops vertically down, rather than feeding the wafer horizontally to the blades. This problem occurs with several users.
