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  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

off-road engine is purchased by the initial purchaser. 
(c)  The  warranty  on  emissions-related  parts  will  be  interpreted  as  follows:  Any 

warranted part that is not scheduled for replacement as required in the Emissions

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

remainder of the period prior to the first scheduled replacement point, and will be 

repaired or replaced at any RYOBI

that replacement point is reached.

 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.
