The California Air Resources Board and Ryobi
Outdoor Products (ROP), are pleased to explain
the emission control system warranty on your
1995 and later small off-road engine. In
California, new small off-road engines must 
be designed, built and equipped to meet the
State's stringent anti-smog standards. ROP 
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 injection system,
the ignition system, and catalytic converter. Also
included may be hoses, belts, connectors and
other emission-related assemblies.

Where a warrantable condition exists, ROP will
repair your small off-road engine at no cost to
you including diagnosis, parts and labor.

The 1995 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 by ROP.

OWNER'S 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. ROP recommends that
you retain all receipts covering maintenance
on your small off-road engine, but ROP
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
should however be aware that ROP 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 Ryobi 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 Ryobi Service Center. For the
nearest location, please contact Ryobi at: 
1-800-345-8746.

Any warranted part which is not scheduled for
replacement, as required maintenance which is
scheduled 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 Ryobi
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 or
warranted parts caused by the use of add-on or
modified parts.

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