EPA Emission Control Warranty Statement

Your Warranty Rights and Obligations

The Environmental Protection Agency and MTD SOUTHWEST INC (MTD) are pleased to explain the emission control

system warranty on your 2005 and later small off-road engine. New small off-road engines must be designed, built and
equipped to meet stringent anti-smog standards. MTD must warrant the emission control system on your small off-road
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 emission control system may include parts such as the carburetor or fuel-injected system, the ignition system, and

catalytic converter. Also included may be hoses, belts, connectors and other emission-related assemblies.

Where a warrantable condition exists, MTD will repair your small off-road engine at no cost to you including diagnosis,

parts and labor.

The 2005 and later small off-road engines are warranted for two years. If any emission-related part  on your engine is

defective, the part will be repaired or replaced my MTD.

Owners Warranty Responsibilities

• As the small off-road engine owner, you are responsible for the performance of the required maintenance listed in your
operator’s manual. MTD recommends that you retain all receipts covering maintenance on your small off-road engine,
but MTD 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 however should be aware that MTD may deny you warranty coverage if your
small off-road engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.

• You are responsible for presenting your small off-road engine to a MTD Authorized Service Center as soon as a
problem exists. The 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 call 1-800-345-8746.

Manufacturer’s Warranty Coverage

• The warranty period begins on the date the engine or equipment is delivered to the retail purchaser.

• The manufacturer warrants to the initial owner and each subsequent purchaser, that the engine is free from defects in
material and workmanship which cause the failure of a warranted part for a period of two years.

• Repair or replacement of warranted part will be performed at no charge to the owner at an Authorized MTD Service
Center. For the nearest location please contact MTD at: 1-800-345-8746.

• Any warranted part which is not scheduled for replacement, as required maintenance or which is scheduled for only
for regular inspection to the effect of “Repair or Replace as Necessary” is warranted for the warranty period. Any
warranted part which is scheduled for replacement as required maintenance will be warranted for the period of time up
to the first scheduled replacement point for that part.

• The owner will not be charged for diagnostic labor which leads to the determination that a warranted part is defective,
if the diagnostic work is performed at an Authorized MTD Service Center.

• The manufacturer is liable for damages to other engine components caused by the failure of a warranted part still
under warranty.

• Failures caused by abuse, neglect or improper maintenance are not covered under warranty.

• The use of add-on or modified parts can be grounds for disallowing a warranty claim. The manufacturer is not liable to
cover failures of warranted parts caused by the use of add-on or modified parts.

• In order to file a claim, go to your nearest Authorized MTD Service Center. Warranty services or repairs will be
provided at all Authorized MTD Service Centers.

• Any manufacturer approved replacement part may be used in the performance of any warranty maintenance or repair
of emission related parts and will be provided without charge to the owner. Any replacement part that is equivalent in
performance or durability  may be used in non-warranty maintenance or repair and will not reduce the warranty
obligations of the manufacturer

• The following components are included in the emission related warranty of the engine, air filter, carburetor, primer, fuel
lines, fuel pick up/ fuel filter, ignition module, spark plug and muffler.
