美国采购需求：台式砂轮机、钻床、线锯、台锯、带锯、吸尘器

I am reaching out regarding a specific bench grinder that has recently experienced some issues. After using the unit, it became excessively hot during operation and, unfortunately, it has stopped functioning altogether. I'm looking for guidance on how to proceed with the warranty process for this item, including any specific steps I need to take to initiate the claim. Could you please provide me with detailed information on the warranty coverage, necessary documentation, and any other requirements needed for me to move forward? Your assistance in clarifying the procedure would be greatly appreciated, as I want to resolve this matter as quickly as possible. Thank you!
