Crown International, 1718 West Mishawaka Road, Elkhart, Indiana 46517-4095 U.S.A. warrants to you, the ORIGINAL 

PURCHASER and ANY SUB SEQUENT OWNER of each NEW Crown product, for a period of five (5) years from the 

date of purchase by the original purchaser (the “warranty period”) that the new Crown product  is free of defects in 

materials and workmanship. We further warrant the new Crown product regardless of the reason for failure, except as 

excluded in this War ranty.

Warranty is only valid within the country in which the product was purchased.

ITEMS EXCLUDED FROM THIS CROWN WARRANTY

                                                                  

This Crown Warranty is in effect only for failure of a new Crown product which occurred within the Warranty Period. It 

does not cover any product which has been damaged because of any inten tional misuse, accident, negligence, or loss 

which is covered under any of your insurance contracts. This Crown Warranty also does not extend to the new Crown 
product if the serial number has been defaced, altered, or removed.

WHAT THE WARRANTOR WILL DO

                                                                                            

We will remedy any defect, regardless of the rea son for failure (except as excluded), by repair, replacement, or refund. 

We may not elect refund unless you agree, or unless we are unable to pro vide replacement, and repair is not practical 

or cannot be timely made. If a refund is elected, then you must make the defective or malfunctioning product available 

to us free and clear of all liens or other encumbrances. The refund will be equal to the actual purchase price, not 

including inter est, insurance, closing costs, and other finance charges less a reasonable depreciation on the product 

from the date of original purchase. War ranty work can only be performed at our autho rized service centers or at the 

factory. Warranty work for some products can only be performed at our factory. We will remedy the defect and ship 

the product from the service center or our factory within a reasonable time after receipt of the defec tive product at our 

authorized service center or our factory. All expenses in remedying the defect, including surface shipping costs in the 

United States, will be borne by us. (You must bear the expense of shipping the product between any for eign country 

and the port of entry in the United States including the return shipment, and all taxes, duties, and other customs fees 
for such for eign shipments.)
