emission control System Warranty Statement (owner’s Defect Warranty rights and obligations)

EMISSION CONTROL WARRANTY COVERAGE IS APPLICABLE TO CERTI-
FIED ENGINES PURCHASED IN CALIFORNIA IN 1995 AND THEREAF-
TER, WHICH ARE USED IN CALIFORNIA, AND TO CERTIFIED MODEL 

YEAR 1997 AND LATER ENGINES WHICH ARE PURCHASED AND USED

CANADA).

california and United States emission control Defects Warranty Statement

The California Air Resources Board (CARB), U.S. EPA and Sears 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. Sears must warrant the emission control system on your 

engine for the periods of time listed below, provided there has been no abuse, 
neglect or improper maintenance of your small off-road engine. Your emis-
sion control system includes parts such as the carburetor, air cleaner, ignition 
system, muffler and catalytic converter. Also included may be connectors and 

other emission related assemblies. Where a warrantable condition exists, Sears 

will repair your small off-road engine at no cost to you including diagnosis, parts 
and labor.

Sears emission control Defects Warranty coverage

Small off-road engines are warranted relative to emission control parts defects 

for a period of one year, subject to provisions set forth below. If any covered 

part on your engine is defective, the part will be repaired or replaced by Sears.

owner’s Warranty responsibilities

As the small off-road engine owner, you are responsible for the performance of 
the required maintenance listed in your Operating and Maintenance Instruc-
tions. Sears recommends that you retain all your receipts covering maintenance 
on your small off-road engine, but Sears 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 Sears may deny you warranty coverage if your small off-road engine 
or a part has failed due to abuse, neglect, improper maintenance or unap-

proved modifications. You are responsible for presenting your small off-road 

engine to an Authorized Sears 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 Sears Service Representative 
at 1-800-469-4663. 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.

Sears emission control Defects Warranty Provisions

The following are specific provisions relative to your Emission Control Defects Warranty Coverage. It is in addition to the Sears engine warranty for non-regulated 
engines found in the Operating and Maintenance Instructions.

2.  Length of Coverage
  Sears warrants to the initial owner and each subsequent purchaser that 

the Warranted Parts shall be free from defects in materials and workman-
ship which caused the failure of the Warranted Parts for a period of one 
year 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 Sears Service Dealer. For emissions warranty 
service contact your nearest Authorized Sears Service Dealer as listed in 
the “Yellow Pages” under “Engines, Gasoline,” “Gasoline Engines,” “Lawn 
Mowers,” or similar category.

4.  Claims and Coverage Exclusions

  Warranty claims shall be filed in accordance with the provisions of the 

Sears Engine Warranty Policy. Warranty coverage shall be excluded for 

failures of Warranted Parts which are not original Sears parts or because 
of abuse, neglect or improper maintenance as set forth in the Sears 
Engine Warranty Policy. Sears 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 Sears Operating and Maintenance Instructions.

6.  Consequential Coverage

  Coverage hereunder shall extend to the failure of any engine components 

caused by the failure of any Warranted Part still under warranty.

            In the USA and Canada, a 24 hour hot line, 

1-800-469-4663

, has a menu of pre-recorded messages offering you engine maintenance information.
