In-Warranty Return Material Procedure

Material may not be returned except by permission of authorized factory service personnel of Sterling, Inc. in New Berlin, Wisconsin. A “Return Goods” tag will be sent to be included with the returned material. Enter the required information on the tag in order to expedite handling at our factories and prompt issuance of credits. All parts shall be returned to the factory designated on the “Return Goods” tag, transportation charges prepaid.

The return of a part does not constitute an order for replacement. Therefore, a purchase order must be entered through your nearest Sterling, Inc. representative. The order should include part number, model number and serial number of the unit involved.

Following our careful inspection of the returned part and if it is determined that the failure is due to faulty material or workmanship, credit will be issued on customer's purchase order.
