CALIFORNIA & US EPA EMISSION CONTROL WARRANTY STATEMENT
The U. S. Environmental Protection Agency (“EPA”), the California Air Resources Board (“CARB”) and Tecumseh Products
Co. are pleased to explain the Federal and California Emission Control Systems Warranty on your new utility or lawn and
garden equipment engine. In California, new 1995 and later utility and lawn and garden equipment engines must be de-
signed, built and equipped to meet the State’s stringent anti-smog standards. In other states, new 1997 and later model year
engines must be designed, built and equipped, at the time of sale, to meet the U.S. EPA regulations for small non-road
engines. Tecumseh Products Co. will warrant the emission control system on your utility or lawn and garden equipment
engine for the periods of time listed below, provided there has been no abuse, neglect, unapproved modification, or improper
maintenance of your utility or lawn and garden equipment engine.
Your emission control system may include parts such as the carburetor, ignition system and exhaust system. Also included
may be the compression release system and other emission-related assemblies.
Where a warrantable condition exists, Tecumseh Products Co. will repair your utility or lawn and garden equipment engine at
no cost to you for diagnosis, parts and labor.
MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE
Emission control systems on 1995 and later model year California utility and lawn and garden equipment engines are
warranted for two years as hereinafter noted. In other states, 1997 and later model year engines are also warranted for two
years. If, during such warranty period, any emission-related part on your engine is defective in materials or workmanship, the
part will be repaired or replaced by Tecumseh Products Co.
OWNER’S WARRANTY RESPONSIBILITIES
As the utility or lawn and garden equipment engine owner, you are responsible for the performance of the required mainte-
nance listed in your Owner’s Manual, but Tecumseh Products Co. will not deny warranty solely due to the lack of receipts or
for your failure to provide written evidence of the performance of all scheduled maintenance.
As the utility or lawn and garden equipment engine owner, you should, however, be aware that Tecumseh Products Co. may
deny you warranty coverage if your utility or lawn and garden equipment or a part thereof has failed due to abuse, neglect,
improper maintenance or unapproved modifications.
You are responsible for presenting your utility or lawn and garden equipment engine to a Tecumseh Authorized Service
Outlet (any Tecumseh Registered Service Dealer, Tecumseh Authorized Service Distributor or Tecumseh Central Ware-
house Distributor) as soon as a problem exists. The warranty repairs should be completed in a reasonable amount of time,
not to exceed 30 days.
Warranty service can be arranged by contacting either a Tecumseh Authorized Service Outlet or by contacting Tecumseh
Products Co., c/o Service Manager, Engine and Transmission Group Service Division, 900 North Street, Grafton, WI 53024-

your new engine. To the extent that there is any conflict in terms between the ECS Warranty and the Tecumseh Products
Co. Warranty, the ECS Warranty shall apply except in any circumstances in which the Tecumseh Products Co. Warranty
may provide a longer warranty period. Both the ECS Warranty and the Tecumseh Products Co. Warranty describe important
rights and obligations with respect to your new engine.
Warranty service can only be performed by a Tecumseh Products Co. Authorized Service Outlet, or by Tecumseh Products
Co. at its factory in Grafton, WI. At the time of requesting warranty service, evidence must be presented of the date of sale
to the original purchaser. The purchaser shall pay any charges for making service calls and/or for transporting the products
to and from the place where the inspection and/or warranty work is performed. The purchaser shall be responsible for any
damage or loss incurred in connection with the transportation of any engine or any part(s) thereof submitted for inspection
and/or warranty work.
