Dear wafersaw users:
The water valve has been repaired!!!  It has not worked properly since January, so everyone has been manually turning the water on and off at the flow meter.
NO LONGER!  The automatic water valve now works!  So, the "New" procedures (actually, the old one, pre-January):
1.  Make sure the flow meter is ON.  The knob should be open, about 1/4 - 1/2 turn counter clockwise from fully closed.  Make sure to check this -- if the water is not on when you cut, you are cutting dry and the blade or your wafer will break.
2.  Water flow can be adjusted only while cutting (using the flow meter knob.)  The flow should be around 10 but probably no more than 15, from the top of the float.
3.  DO NOT turn the flow meter knob to the off position.  It could mess up the next person.
Any problems, please report on Coral.
Thanks!
Team Etch
