identical in allmaterial respects to the engine described in the manufacturer’s
application for certification. The warranty period begins on the date the engine or
equipment is delivered to an ultimate purchaser.
The warranty on emissions-related parts is as follows:

maintenance in the Operator’s Manual supplied, is warranted for the warranty
period stated above. If any such part fails during the period of warranty
coverage, the part will be repaired or replaced by B&S at no charge to
the owner. Any such part repaired or replaced under the warranty will be
warranted for the remaining warranty period.

above. Any such part repaired or replaced under warranty will be warranted
for the remaining warranty period.
• Any warranted part that is scheduled for replacement as required

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 or replaced
by B&S at no charge to the owner. Any such part repaired or replaced under
warranty will be warranted for the remainder of the period prior to the first
scheduled replacement point for the part.
• Add-on or modified parts that are not exempted may not be used. The use of
any non-exempted add-on or modified parts by the owner will be grounds for
disallowing a warranty claim. The manufacturer will not be liable to warrant
failures of warranted parts caused by the use of a non-exempted add-on or
