To avoid misunderstanding, some of the causes of engine failure that the warranty does not cover are listed below. NORMAL WEAR Our products, like all mechanical devices, need periodic parts service and replacement to perform correctly.

Additionally, ATK’s warranty would not apply if damage to the product has occurred because of misuse, lack of routine maintenance, shipping, handling, warehousing, or improper installation. Similarly, our warranty is void if the serial number of the product has been removed or the product has been altered or modified. IMPROPER MAINTENANCE The life of a mechanical device depends upon the conditions under which it operates and the care it receives. Wear, when caused by dirt, dust, spark plug cleaning grit, or other abrasive material that has entered the engine because of improper maintenance, is not covered by warranty. DO-IT-YOURSELF INSTALLATION AND REPAIRS DIY installations, DIY repairs, repairs performed by unlicensed repair facilities, or repairs made to units not originally installed by a Licensed Automotive Repair Facility do not qualify for labor reimbursements. Warranty repairs must be completed by Licensed Automotive Repair Facilities. WHAT THIS WARRANTY DOES NOT COVER ATK’s warranty does not extend to repairs required because of: 1. Problems caused by parts that are not ATK parts. 2. Damage as a result of overheating, lack of lubrication, fuel wash, or contamination. 3.
