Checked all three (End-X, End-Y, & CS) dust monitor vacuum pumps. Both end station pumps are running great. There temps are all in range and there is no accumulation of carbon dust on the mufflers. 

   The CS pump (which was rebuilt on 09/04) new vanes have broken in well and the pump is running with low temps and no carbon dust accumulations. Made an adjustment in the air bypass to bring the vacuum pressure to 18inHg. This adjustment is normal for a newly rebuild pump.
