Emission Control System Warranty Statement (Owner’s Defect Warranty Rights and Obligations)

EMISSION CONTROL WARRANTY COVERAGE IS APPLICABLE
TO CERTIFIED ENGINES PURCHASED IN CALIFORNIA IN 1995
AND THEREAFTER, WHICH ARE USED IN CALIFORNIA, AND

TO CERTIFIED MODEL YEAR 1997 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 are
pleased to explain the Emission Control System Warranty on your
model year 2000 and later small off-road engine (SORE). In California,
new small off-road engines must be designed, built and equipped to
meet the State’s stringent anti-smog standards. Elsewhere in the
United States, new non-road, spark-ignition engines certified for model
year 1997 and later, must meet similar standards set forth by the U.S.
EPA. B&S must warrant the emission control system on your engine for

the periods of time listed below, provided there has been no abuse, ne-
glect or improper maintenance of your small off-road engine.
Your emission control system includes parts such as the carburetor,
air cleaner, ignition system, muffler and catalytic converter. Also in-
cluded may be connectors and other emission related assemblies.
Where a warrantable condition exists, B&S will repair your small off-
road engine at no cost to you including diagnosis, parts and labor.

Briggs & Stratton Emission Control Defects Warranty Coverage

Small off-road engines are warranted relative to emission control
parts defects for a period of two years, subject to provisions set forth

below. If any covered part on your engine is defective, the part will be
repaired or replaced by B&S.

Owner’s Warranty Responsibilities

As the small off-road engine owner, you are responsible for the per-
formance of the required maintenance listed in your Operating and
Maintenance Instructions. B&S recommends that you retain all your
receipts covering maintenance on your small off-road engine, but
B&S cannot deny warranty solely for the lack of receipts or for your
failure to ensure the performance of all scheduled maintenance.
As the small off-road engine owner, you should however be aware
that B&S may deny you warranty coverage if your small off-road en-
gine or a part has failed due to abuse, neglect, improper mainte-
nance or unapproved modifications.

You are responsible for presenting your small off-road engine to an
Authorized B&S 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 re-
sponsibilities, you should contact a B&S Service Representative at
1-414-259-5262.
The emission warranty is a defects warranty. Defects are judged on
normal engine performance. The warranty is not related to an in-use
emission test.

ered to a retail purchaser.

quired maintenance or which is scheduled only for regular inspec-
tion to the effect of “repair or replace as necessary” shall be war-
ranted 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

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 Operating and Maintenance Instructions.

6.

Coverage hereunder shall extend to the failure of any engine
components caused by the failure of any Warranted Part still un-
der warranty.
