The warranty on emissions-related parts is as follows:
• Anywarrantedpart that is not scheduled for replacement as required
maintenance in the owner's manual supplied, is warranted for the war-
ranty period stated above. If any such part fails during the period of 
warranty coverage, that part will be repaired or replaced at no charge to

warranted for the remaining warranty period.
• Anywarrantedpartthatisscheduledonlyforregularinspectioninthe

such part repaired or replaced under warranty will be warranted for 
the remaining warranty period.
• Anywarrantedpartthatisscheduledforreplacementasrequiredmain-

time prior to the first scheduled replacement point for that part. If the 
part fails prior to the first scheduled replacement, the part will be repaired

Board may not be used. The use of any nonexempted add on or 
modified parts by the owner will be grounds for disallowing a war-
ranty claim. The manufacturer will not be liable to warrant failures 
of warranted parts caused by the use of a nonexempted add on or 
modified part.
These items will be covered for a period of two years from the date 
of the original purchase. Viper warrants that: the components are 
designed, built and equipped so as to conform with all applicable 
regulations adopted by the EPA; that they are free from defects in ma-
terial and workmanship that could cause failure to the engine or other; 
and that the components used are identical in all material respects to 
the engine described in the manufacturer's application for certifica-
tion. The warranty period begins on the date the engine is originally 
purchased. 
MAINTENANCE AND REPAIR REQUIREMENTS
The owner is responsible for the proper use and maintenance of the 
engine. Ardisam, Inc. recommends that all receipts and records cov-
ering the performance of regular maintenance be retained in case 
questions arise. If the engine is resold during the warranty period, 
the maintenance records should be transferred to each subsequent 
owner. Ardisam, Inc. reserves the right to deny warranty coverage if 
the engine has not been properly maintained; however, Ardisam, Inc. 
may not deny warranty repairs solely because of the lack of repair 
maintenance or failure to keep maintenance records.
Normal maintenance replacement or repair of emission control devices 
and systems may be performed by any repair establishment or individuals;  
however, warranty repairs must be performed by an Ardisam authorized 
service center. Any replacement parts or service that is equivalent in 
performance and durability may be used in non-warranty maintenance 
or repairs, and shall not reduce the warranty obligations of the engine 
manufacturer.
