WARRANTY  
THE FOLLOWING CALIFORNIA AIR RESOURCES BOARD (CARB) STATEMENT ONLY APPLIES TO MODEL NUM-  
BERS REqUIRED TO MEET THE CARB REqUIREMENTS.  
TECHTRONIC INDUSTRIES NORTH AMERICA, INC., LIMITED WARRANTY STATEMENT FOR FEDERAL  
AND CALIFORNIA EMISSION CONTROL SYSTEMS NON-ROAD AND SMALL OFF-ROAD ENGINES  
YOUR WARRANTY RIGHTS AND OBLIGATIONS  
The U.S. Environmental Protection Agency (EPA), the California Air Resources Board  
(CARB), and Techtronic Industries North America, Inc., are pleased to explain the  
Emissions Control System Warranty on your ꢀ007 model year non-road or small off-  
road engine. In California, new equipment that uses small off-road engines must be  
designed, built, and equipped to meet the state’s stringent anti-smog standards. In  
other states, new ꢀ000 and later model year non-road 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 non-road 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. Techtronic  
Industries North America, Inc., must warrant the emission control system on your  
non-road or small off-road engine for the period of time listed above provided there  
has been no abuse, neglect, or improper maintenance of your non-road or small  
off-road engine.  
Your emission control system may include parts such as the carburetor or fuel injection  
system, the ignition system, catalytic converters, fuel tanks, valves, filters, clamps,  
connectors, and other associated components. Also included may be hoses, belts  
and connectors, and other emission-related assemblies.  
Where a warrantable condition exists, Techtronic Industries North America, Inc., will  
repair your non-road or small off-road engine at no cost to you, including diagno-  
sis, parts, and labor performed at an authorized service center for RYOBI® brand  
outdoor products.  
Techtronic Industries North America, Inc., shall remedy warranty defects at any  
authorized RYOBI® Authorized Service Center, including any distribution center  
that may be franchised to service the subject engines. Any diagnostic work done  
at a RYOBI® Authorized Service Center shall be free of charge to the owner if such  
work determines that a warranted part is defective. Any manufacturer-approved or  
equivalent replacement part may be used for any warranty maintenance or repairs  
on emission-related parts, and must be provided free of charge to the owner if the  
part is still under warranty. Techtronic Industries North America, Inc., is liable for  
damages to other engine components caused by the failure of a warranted part  
still under warranty.  
Add-on or modified parts that are not exempted by the California Air Resource Board  
may not be used. The use of any non-exempted add-on or modified parts will be  
grounds for disallowing a warranty claim. Techtronic Industries North America, Inc.,  
will not be liable to warrant failures of warranted parts caused by the use of a non-  
exempted add-on or modified part.  
The California Air Resources Board’s Emission Warranty Parts List specifically defines  
the emission-related warranted parts. (EPA’s regulations do not include a parts list,  
but the EPA considers emission-related warranted parts to include all the parts listed  
below.) Techtronic Industries North America, Inc., will provide any documents that  
describe its warranty procedures or policies within five days upon request by the  
California Air Resources Board.

Techtronic Industries North America, Inc., recommends that you retain all re-  
ceipts covering maintenance on your non-road or small off-road engine, but  
Techtronic Industries North America, Inc., cannot deny warranty solely for the  
lack of receipts or for your failure to ensure the performance of all scheduled

not reduce the warranty obligations of Techtronic Industries North America, Inc.

improper maintenance, or unapproved modifications.  
(c) You are responsible for presenting your non-road or small off-road 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 30 days.

non-road or small off-road engine is designed, built, and equipped at the time of sale  
to conform with all applicable regulations adopted by the California Air Resources  
Board or the United States Environmental Protection Agency; and that it is free from  
defects in materials and workmanship which cause the engine to fail to conform with

years. If any such part (including any part that is scheduled only for regular inspection)  
fails during the period of warranty coverage, it will be repaired or replaced at any  
RYOBI® Authorized Service Center at no charge. Any such part repaired or replaced  
under warranty will be warranted for the remaining warranty period. A statement to  
the effect of “repair or replace as necessary” would not reduce the period of war-  
ranty coverage. Any warranted part that is scheduled for replacement as required  
maintenance in the Emissions Maintenance Schedule and Warranty Parts List is  
warranted for the period of time prior to the first scheduled replacement point for  
that part. Any such part repaired or replaced under warranty is warranted for the  
remainder of the period prior to the first scheduled replacement point, and will be  
repaired or replaced at any RYOBI® Authorized Service Center for no charge until  
that replacement point is reached.  
(ii) Vacuum, temperature, and time sensitive valves and switches.  
(iii) Hoses, belts, connectors, and assemblies.

instructions for its maintenance and use by the owner.

indicates the number of operating hours for which the engine has been shown to  
meet Federal emission requirements. Category C=50 hours, B=1ꢀ5 hours, and
