WARNING:
A wet or dirty air filter can affect the way the engine starts,
performs, and wears. The air filter should be checked and
cleaned after 8 hours of operation. If working in dusty soil,
check the air filter after each refueling.
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
For best performance, the air filter should be replaced once
each year.

shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in
serious personal injury or property damage.
Reinstall the air filter.
NOTE: Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
Reinstall the cover.
Tighten knob to secure.

away from corrosive agents such as garden chemicals
and de-icing salts.
Depending on the type of fuel used, the type and amount of
oil used, and/or your operating conditions, the exhaust port,
muffler, and/or spark arrestor screen may become blocked
with carbon deposits. If you notice a power loss with your
gas powered tool, you may need to remove these deposits
to restore performance. We highly recommend that only
qualified service technicians perform this service.

storage and handling of gasoline. Excess fuel should be
used up in other 2-cycle engine powered equipment.
FUEL CAP
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine per-
formance. If performance improves when the fuel cap is
loosened, the check valve may be faulty or filter clogged.
Replace the fuel cap if required.

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, and the catalytic con-
verter. 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 diagnosis (if the diagnostic work is performed at an authorized service center for RYOBI® brand outdoor products),
parts, and labor.
MANUFACTURER’S WARRANTY COVERAGE:
The 1995 and later small off-road engines are warranted for two years in California. In other states, 1997 and later model year non-road
engines are also warranted for two years. If any emission-related part on your engine is defective, the part will be repaired or replaced by
Techtronic Industries North America, Inc., free of charge.
OWNER’S WARRANTY RESPONSIBILITIES
(a) As the non-road or small off-road engine owner, you are responsible for the performance of required maintenance listed in your operator’s
manual. Techtronic Industries North America, Inc., recommends that you retain all receipts 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 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 the engine manufacturer.
(b) As the non-road or small off-road engine owner, you should be aware, however, that Techtronic Industries North America, Inc., may deny you
warranty coverage if your non-road or small off-road engine or a part has failed due to abuse, neglect, improper maintenance, or unap-
proved 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.
If you have any questions regarding your warranty rights and responsibilities, you should contact a Techtronic Industries North America,
Inc., Customer Representative at 1-800-860-4050.
COVERAGE:
Techtronic Industries North America, Inc., warrants to the ultimate purchaser and each subsequent purchaser that your non-road or small
off-road engine will be designed, built, and equipped at the time of sale, to meet all applicable regulations. Techtronic Industries North
America, Inc., also warrants to the initial purchaser and each subsequent purchaser that your non-road or small off-road 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. The
1995 and later small off-road engines are warranted for two years in California. In all other states for 1997 and later model years, EPA requires
manufacturers to warrant non-road engines for two years. These warranty periods will begin on the date the non-road or small off-road
engine is purchased by the initial purchaser. If any emission-related part on your engine is defective, the part will be replaced by Techtronic
Industries North America, Inc., at no cost to the owner.
Techtronic Industries North America, Inc., shall remedy warranty defects at any authorized RYOBI engine dealer or warranty sta-
tion. Any authorized work done at an authorized dealer or warranty station shall be free of charge to the owner if such work deter-
mines 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. Tech-
tronics North America, Inc., is liable for damages to other engine components caused by the failure of a warranted part still under warranty.
The California Air Resources Board’s Emission Warranty Parts List specifically defines the emission-related warranted parts. (EPA’s regula-
tions do not include a parts list, but EPA considers emission-related warranted parts to include all the parts listed below.)
These warranted parts are: Carburetor, Spark Plug, Ignition, Air Filter, and Fuel Filter.
MAINTENANCE REQUIREMENTS
The owner is responsible for the performance of the required maintenance as defined by Techtronic Industries North America, Inc., in the
operator’s manual.
LIMITATIONS
The Emission Control Systems Warranty shall not cover any of the following:
(a) repair or replacement required because of misuse or neglect, lack of required maintenance, repairs improperly performed, or replace-
ments not conforming to Techtronic Industries North America, Inc., specifications that adversely affect performance and/or durability,
and alterations or modifications not recommended or approved in writing by Techtronic Industries North America, Inc., and
(b) replacement of parts and other services and adjustments necessary for required maintenance at and after the first scheduled replace-
ment point.
The Emissions Compliance Period referred to on the Emissions Compliance label indicates the number of operating hours for which the
engine has been shown to meet Federal emission requirements. Category C=50 hours, B=125 hours, and A=300 hours.
