As an UPDATE to the thread, a gentleman named Craig from Grizzly Tech Support just called me out of the blue after finding my post here to check on the saw. He apologized for the incorrect information provided me previously about the hand wheels/knobs and extended support for any problems I may have with the plastic ones for the first year or so. Also offered some advice on saw and mobile base setup which was really nice.
Very nice gesture by Grizzly to monitor the forum and to call me unsolicited. I'm gaining nothing by sharing this as I was offered no form of reimbursement and I requested none. Just thought it was a good sign of future customer support should I have any issues with the saw or the plastic items.
