Briggs & Stratton Daihatsu L.L.C. (B&S D), the California Air Resources Board (CARB)
and the United States Environmental Protection Agency (U.S. EPA) Emission Control
System Warranty Statement
(Owner’s Defect Warranty Rights and Obligations)
EMISSION CONTROL WARRANTY COVERAGE IS APPLICABLE TO CERTIFIED MODEL YEAR 2001 AND LATER
ENGINES, WHICH ARE PURCHASED AND USED IN CALIFORNIA, AND TO CERTIFIED MODEL YEAR 2001 AND
LATER ENGINES, WHICH ARE PURCHASED AND USED ELSEWHERE IN THE UNITED STATES.
California and United States Emission Control Defects Warranty Statement
The California Air Resources Board (CARB), U.S. EPA and B&S D are pleased to explain the Emission Control System
Warranty on your model year 2001 and later Non-road Compression-ignition engine. In California new Non-road Compres-
sion-ignition engines must be designed, built and equipped to meet the State’s stringent anti-smog standards. Elsewhere
in the United States, new Non-road Compression-ignition engines certified for model year 2001 and later, must meet
similar standards set forth by the U.S. EPA. B&S D must warrant the emission control system on your engine for the period
of time listed below, provided there has been no abuse, neglect or improper maintenance of your Non-road Compression-
ignition engine. Your emission control system includes parts such as the air cleaner, ignition system, and muffler. Also
included may be connectors and other emission related assemblies. Where a warrantable condition exists, B&S D will
repair your Non-road Compression-ignition engine at no cost to you including diagnosis, parts and labor.
Briggs & Stratton Daihatsu Emission Control Defects Warranty Coverage
Non-road Compression-ignition engines are warranted relative to emission control part defects for a period of 1,500 hours
or two years, whichever first occurs, subject to provisions set forth below. If any covered part on your Non-road Compres-
sion-ignition engine is defective, the part will be repaired or replaced by B&S D.
Owner’s Warranty Responsibilities
As the Non-road Compression-ignition engine owner, you are responsible for the performance of the required mainte-
nance listed in your Operating and Maintenance Instructions. B&S D recommends that you retain all your receipts covering
maintenance on your Non-road Compression-ignition engine, but B&S D cannot deny warranty solely for the lack of
receipts or for your failure to ensure the performance of all scheduled maintenance. As the Non-road Compression-ignition
engine owner, you should however be aware the B&S D may deny you warranty coverage if your Non-road Compression-
ignition engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications. You are
responsible for presenting your Non-road Compression-ignition engine to an Authorized B&S D Service Dealer as soon as
a problem exists. The undisputed warranty repairs should be completed in a reasonable amount of time, not to exceed 30
days. If you have any questions regarding your warranty rights and responsibilities, you should contact a B&S D Service
Representative at 1 [phone].

rials and workmanship which caused the failure of the Warranted Parts for a period of 1,500 hours or two years, whichever first
occurs, from the date the engine is delivered to a retail purchaser.
3. No Charge
Repair or replacement of any Warranted Part will be performed at no charge to the owner, including diagnostic labor which
leads to the determination that a Warranted Part is defective, if the diagnostic work is performed at an Authorized B&S D

low Pages”under “Engines, Gasoline,” “Gasoline Engines,” “Lawn Mowers,”or similar category.
4. Claims and Coverage Exclusions

shall be excluded for failures of Warranted Parts which are not original B&S D parts or because of abuse, neglect or improp-
er maintenance as set forth in the B&S D Engine Warranty Policy. B&S D is not liable to cover failures of Warranted Parts
caused by the use of add-on, non-original, or modified parts.
5. Maintenance
Any Warranted Part which is not scheduled for replacement as required maintenance or which is scheduled only for regular
inspection to the effect of “repair or replace as necessary”shall be warranted as to defects for the warranty period. Any
Warranted Part which is scheduled for replacement as required maintenance shall be warranted as to defects only for the
period of time up to the first scheduled replacement for that part. Any replacement part that is equivalent in performance and
durability may be used in the performance of any maintenance or repairs. The owner is responsible for the performance of
all required maintenance, as defined in the B&S D Operating & Maintenance Instructions.
