Federal Emission Control Warranty Statement

A Two-Year Limited Warranty

Your Warranty Rights and Obligations
The U.S. Environmental Protection Agency (EPA), The Toro Company, and its affiliate, Toro Warranty Company, are pleased to explain the emission control system warranty on your 2009 and later utility/lawn/garden equipment engine. 2009 and later model year utility/lawn/garden equipment engines must be designed, built and equipped, at the time of sale, to meet the U.S. EPA regulations for small non-road engines. The equipment engine must be free from defects in materials and workmanship, which cause it to fail to conform with U.S. EPA standards, for the first two years of engine use from the date of sale to the ultimate purchaser. The Toro Company and its affiliate, Toro Warranty Company, warrant the emission control system on your utility/lawn/garden equipment engine for the period of time listed above, provided there has been no abuse, neglect, or improper maintenance of your utility/lawn/garden equipment engine.
Your emission control system may include parts such as the carburetor or fuel injection system, the ignition system, and catalytic converter. Also included may be fuel lines, fuel line fasteners, connectors, and other emission-related assemblies.
Where a warrantable condition exists, The Toro Company and its affiliate, Toro Warranty Company, promise to repair your engine at no cost to you, including diagnosis, parts, and labor.

Manufacturer’s Warranty Coverage
The Toro Company and its affiliate, Toro Warranty Company, pursuant to an agreement between them, jointly warrant the 2009 and later utility/lawn/garden equipment engines for two years from the date of delivery. If any emission- related part on your engine is defective in materials or workmanship, we will repair or replace the part, free of charge.

Owner Responsibilities
As the engine owner, you are responsible for the performance of the required maintenance listed in your Operator’s Manual. We recommend that you retain all receipts covering maintenance on your equipment, but we cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
Any replacement part or service that is equivalent in performance and durability may be used in non-warranty maintenance or repairs, and shall not reduce our warranty obligation.
As the engine owner, you should be aware that we may deny you warranty coverage if your engine or a part has failed due to abuse, neglect, improper maintenance, or unapproved modifications or parts.
You are responsible for presenting your equipment engine to an Authorized Service Dealer as soon as a problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed thirty (30) days.

Warranted Parts
The warranty period begins on the date the engine or equipment is delivered to a retail purchaser. The Toro Company and its affiliate, Toro Warranty Company, jointly warrant to the initial owner and each subsequent purchaser that the engine is free from defects in materials and workmanship, which cause the engine to fail to conform with applicable regulations, for a period of two years.
Failures caused by abuse, neglect, or improper maintenance are not covered. The use of add-on or modified parts can be grounds for disallowing a warranty claim. We are not liable to cover failures of warranted parts caused by the use of add-on or modified parts. We are liable for damages to other engine components caused by the failure of a warranted part still under warranty. The owner is responsible for the performance of the required maintenance, as defined in the Operator’s Manual.
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 for the warranty period. Any warranted part which is scheduled for replacement as required maintenance shall be warranted for the period of time up to the first scheduled replacement point for that part. Coverage under this warranty extends only to the parts listed below (the emissions system parts) to the extent that these parts were present on the engine when purchased.
