The warranty period commences on the day of purchase by the original purchaser. We provide twelve month limited manufacturer warranty to repair or replace, at our option, any new product excluding special on sale product which, under normal conditions of use and service, proves to be defective in material or workmanship. This warranty, however, does not cover any labor or any freight costs incurred in diagnosis of defects, removal or re-installation or transportation of a product, nor does it cover any contingent expenses. This warranty is limited to the original purchaser, i.e. is not transferable to subsequent owners of the product. Specifically excluded from this warranty are failures caused by misuse, negligence, modification, abuse, improper application, installation or operation, or by unauthorized service or use of unauthorized parts.
