If the aluminum or stainless steel frame fails structurally (i.e., broken frame or welds) under normal use or conditions, and falls within the warranty period, and identical materials are unavailable for repair or replacement, Caluco reserves the right to substitute materials of equal or better quality. Caluco will pay within one year from the date of purchase, shipping costs in the continental United States to repair or replace a defective frame. Spare parts are not under warranty. After one year from the date of purchase, the original retail purchaser will be responsible for packing and shipping cost. The warranty covers only normal usage. No warranty applies to any condition resulting from misuse or abuse, or any condition resulting from incorrect or inadequate maintenance, cleaning, or care. Caluco does not warrant against damage caused by acts of nature, exposure to extreme climate conditions, ocean air, exposure to suntan oil or other chemicals, normal fading or weathering, scratching or chipping of the finish.
