Maintenance and Customer Service

Your Oreck vacuum cleaner is a product of precise engineering. The motor bearings are permanently lubricated and should not be oiled. If you require additional information or have problems with your Oreck vacuum, you may call ORECK customer service at:

US: 1-800-989-3535 Canada: 1-888-676-7325

Please specify the model number and serial/code number which can be found on the data plate on the back of the vacuum.

Save your sales or purchase slip. Should your Oreck require warranty service in the U.S.A., present this slip to the Authorized Service Center as your proof of purchase date or, in Canada, call customer service.

Polarized Plug Notice

This product is equipped with a polarized alternating current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact an electrician to replace the obsolete outlet. Do not defeat the purpose of the polarized plug.

Microban® Antimicrobial Protection

Oreck added Microban® technology to various touch points, including the handle, outer bag, top cover, lamp housing and baseplate while manufacturing this upright vacuum cleaner in order to provide you with antimicrobial protection that continuously fights the growth of microbes that can cause stains, odors and product degradation. When microbes, such as bacteria, mold and mildew come in contact with the product surface, Microban penetrates the cell wall and disrupts key functions so they cannot grow or reproduce. Your Oreck will stay cleaner, longer.
