DISCLAIMER: I don’t speak for, nor on behalf of, the hosts of this website or Hamilton Beach.
So with that said, I’ll clarify that those of us frequenting or asking/answering questions here are doing so to address issues on COMMERCIAL kitchen appliances.
A commercial electric can opener costs W-A-A-A-Y more than the one you’ve asked about. I checked the purchase price on your model and my thinking is that yours falls into the category of being the disposable variety, for which the manufacturer didn’t see the need to provide a parts breakdown for.
FWIW, I plugged in your model number at their PARTS & ACCESSORIES website page. It said “No parts were found. Please check your search criteria and try again.”
So again, I recommend that you call them. Their phone number is in your SmoothTouch™ Can Opener (76606Z) USE AND CARE GUIDE.
