Reminder: always watch loading and unloading

Pquest users:
Please remember to watch *every load and unload *through the viewport to 
make sure the wafer is transferred correctly.  If you see the wafer 
fall, pressing "ESC" on the keyboard will hault all mechanical movement 
before it gets crushed by the arm.  That way you can save the wafer, and 
the chamber does not get covered in wafer fragments.

This is especially important after major maintenance (right now) as it 
is tricky to align everything properly.  Also if you watch/identify 
where the wafer gets mishandled, it helps maintenance troubleshoot the 
problem.

Thanks,
Tom
