Inquiry (采购产品): Mary Ann We purchased a Mary Ann sifter approx. 1 month ago. When we first started her up she was as quiet as could be. However now she has developed a squeaking noise when she runs. This niose occurs whether I am using 8" or 12" screens. It seems to be coming from the top of the three shafts inside the box. We didn't put on any lubricate as it says not to in the book. I hope you can help us with this problem as we do love Mary Ann.Thanks Cathie. **** Hidden Message ***** Cathie Fickling 2448 Metrocenter Blvd. West Palm Beach, FL 33407 USA Company: Nodares and Assoc.
