PRODUCT: KEYS CARDIOMAX 520 UPRIGHT
HOME USE WARRANTY: Parts: 1 year
This Limited Warranty applies in the United States and Canada to products manufactured or distributed by Keys
Fitness Products, LP (“Keys”) under the KEYS brand name. The warranty period to the original purchaser is listed above
in the table.
Keys warrants that the Product you have purchased for use from Keys or from an authorized Keys reseller is free
from defects in materials or workmanship under normal use during the warranty period. Your sales receipt, showing the
date of purchase of the Product, is your proof of purchase. This warranty only extends to you, the original purchaser. It is
not transferable to anyone who subsequently purchases the Product from you. It excludes expendable parts. This
Limited Warranty becomes VALID ONLY if the product is purchased through a Keys Fitness authorized dealer unless
otherwise authorized by Keys Fitness in writing.
During the warranty period Keys will repair or replace (at Keys' option) the product if it becomes defective, malfunctions, or otherwise fails to conform with this Limited Warranty under normal use. In repairing the Product, Keys may
replace defective parts, or at the option of Keys, serviceable used parts that are equivalent to new parts in performance.
All exchanged parts and Products replaced under this warranty will become the property of Keys. Keys reserves the
right to change manufacturers of any part to cover any existing warranty.
This warranty DOES NOT COVER shipping charges, export taxes, custom duties and taxes, or any other charges
associated with transportation of the parts or Product.
To obtain warranty service, you must contact a Keys authorized retailer, service technician or Keys Fitness at our
phone numbers located in this manual. Any parts determined to be defective must be returned to Keys to obtain warranty service. You must prepay any shipping charges, export taxes, custom duties and taxes, or any other charges associated with transportation of the parts or Product. In addition, you are responsible for insuring any parts or Product
shipped or returned. You assume the risk of loss during shipment. You must present Keys with proof-of-purchase documents (including the date of purchase). Any evidence of alteration, erasing or forgery of proof-of-purchase documents
will be cause to void this Limited Warranty.
This warranty does not extend to any product not purchased from Keys or from an authorized Keys reseller. This
Limited Warranty does not extend to any Product that has been damaged or rendered defective; (a) as a result of accident, misuse, or abuse; (b) by the use of parts not manufactured or sold by Keys; (c) by modification of the Product or
normal wear and tear; (d) operation on incorrect power supplies; or (e) as a result of service by anyone other than Keys,
or an authorized Keys warranty service provider. Product on which the serial number has been defaced or removed is
not eligible for warranty service. Should any Product submitted for warranty service be found ineligible, an estimate of
repair cost will be furnished and the repair will be made if requested by you upon Keys' receipt of payment or acceptable
arrangements for payment.
EXCEPT AS EXPRESSLY SET FORTH IN THIS WARRANTY, KEYS MAKES NO OTHER WARRANTIES,
EXPRESSED OR IMPLIED, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. KEYS EXPRESSLY DISCLAIMS ALL WARRANTIES NOT STATED IN THIS LIMITED WARRANTY. ANY IMPLIED WARRANTIES THAT MAY BE IMPOSED BY LAW ARE LIMITED TO THE TERMS OF THIS
