SPECIFIC SAFETY RULES FOR TRIMMER
USE
Replace string head if cracked, chipped, or damaged
in any way. Be sure the string head or blade is properly
installedandsecurelyfastened.Failuretodosocancause
serious injury.
sure blade is installed correctly and securely fastened
before each use. Failure to do so can cause serious
injury.
Use only the manufacturer’s replacement Tri-Arc® blade
intended for use on this brushcutter. Do not use any other
blade. To install any other brand blade or cutting head to
this brushcutter can result in serious personal injury.
Make sure all guards, straps, deflectors, and handles are
properly and securely attached.
Do not attach any blade to this product without installing
all required parts. Failure to use proper parts can cause
the blade to fly off and seriously injure the operator and
or bystanders.
The Tri-Arc® blade is suited for cutting thicker weeds or
pulpy stalks only. Do not use for any other purpose. Never
use the Tri-Arc® blade to cut woody brush.
Use only the manufacturer’s replacement string in the
cutting head. Do not use any other cutting attachment.
To install any other brand of cutting head to this string
trimmer can result in serious personal injury.
Never operate unit without the grass deflector in place
and in good condition.
Maintain a firm grip on both handles while trimming. Keep
string head below waist level. Never cut with the string
head located over 30 in. or more above the ground.
Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction that may occur when
the spinning blade contacts anything it cannot cut. This
contact may cause the blade to stop for an instant, and
suddenly “thrust” the unit away from the object that was
hit. This reaction can be violent enough to cause the op-
erator to lose control of the unit. Blade thrust can occur
without warning if the blade snags, stalls, or binds. This is
more likely to occur in areas where it is difficult to see the
material being cut. For cutting ease and safety, approach
the weeds being cut from the right to the left. In the event
an unexpected object or woody stock is encountered, this
could minimize the blade thrust reaction.
SPECIFIC SAFETY RULES FOR BRUSH-
CUTTER AND BLADE USE
After engine stops, keep rotating blade in thicker weeds
or pulpy stalks until it stops.
Do not operate the brushcutter unless the brushcutter
guard is firmly secured in place and in good condition.
Use heavy gloves when operating the brushcutter and
when installing or removing blades.
Always stop the engine and remove the spark plug wire
before attempting to remove any obstruction caught or
jammed in the blade or before removing and installing
the blade.
Never cut any material over 1/2 in. diameter.
Always wear the shoulder harness when using the brush-
cutter and adjust to a comfortable operating position.
Maintain a firm grip on both handles while cutting with a
blade. Keep the blade away from your body and below
waist level.
Do not attempt to touch or stop the blade when it is
rotating.
A coasting blade can cause injury while it continues
to spin after the engine is stopped or throttle trigger
released. Maintain proper control until the blade has
completely stopped rotating.
Never use the brushcutter with the blade located 30 in.or
more above the ground level.

OPERATION
FUELING AND REFUELING THE TRIMMER
WARNING:
FUEL MIXTURE
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
This product is powered by a 2-cycle engine and requires
pre-mixing gasoline and 2-cycle oil. Pre-mix unleaded
gasoline and 2-cycle engine oil in a clean 1 gallon container
approved for gasoline.
Recommended fuel: This engine is certified to operate on
unleaded gasoline intended for automotive use.
Mix a high quality synthetic 2-cycle engine oil at 2.6 oz. per
gallon (US).
Do not use automotive oil or 2-cycle outboard oil.
Hold the trimmer with your right hand on the rear handle and
your left hand on the front handle. Keep a firm grip with both
hands while in operation. Trimmer should be held at a com-
fortable position with the rear handle about hip height.
Always operate trimmer at full throttle. Cut tall grass from
the top down. This will prevent grass from wrapping around
the shaft housing and string head which could cause
damage from overheating. If grass becomes wrapped around
the string head, STOP THE ENGINE, disconnect the spark
plug wire, and remove the grass. Prolonged cutting at partial
throttle will result in oil dripping from the muffler.
DO NOT mix quantities larger than usable in a 30 day
period.

Hold the brushcutter with your right hand on the rear handle
and your left hand on the “J” Handle. Keep a firm grip with

reaction of the cutting blade.
left in a broad sweeping action from side to side.
Use only the Tri-Arc® blade. To install any other brand
blade or cutting head to this brushcutter can result in
serious personal injury.
PROPER
OPERATING
POSITION
Adjust the shoulder harness to position the brushcutter
at a comfortable operating position and to assure that the
shoulder harness will reduce the risk of operator contact
with the blade.
BLADE THRUST
Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction that may occur when the
spinning blade contacts anything it cannot cut. This contact
may cause the blade to stop for an instant, and suddenly
“thrust” the unit away from the object that was hit. This re-
action can be violent enough to cause the operator to lose
control of the unit. Blade thrust can occur without warning
if the blade snags, stalls, or binds. This is more likely to oc-
cur in areas where it is difficult to see the material being cut.
For cutting ease and safety, approach the weeds being cut
with the brushcutter from the right to the left. In the event
an unexpected object or woody stock is encountered, this
practice could minimize the blade thrust reaction.
Fig. 19
®
TRI-ARC BLADE
DIRECTION OF ROTATION
The Tri-Arc® blade is suited only for thicker weeds and pulpy
stalks. When the blade becomes dull, it can be turned over
to extend the life of the blade. Do not sharpen the Tri-Arc®
blade.
Use only Tri-Arc® blade, part number AP04105, available at
your local retailer.
CUTTING TECHNIQUE − BLADE
WARNING:
Extreme care must be taken when using blades to en-
sure safe operation. Read the safety information for safe
operation using the blade, refer to Specific Safety Rules
for Brushcutter and Blade Use earlier in this manual.
CUTTING AREA
Fig. 20
Always hold brushcutter on your right side with both hands
when operating. Use a firm grip on both handles.
Maintain your grip and balance on both feet. Position
yourself so that you will not be drawn off balance by the

WARRANTY
THE FOLLOWING CALIFORNIA AIR RESOURCES BOARD (CARB) STATEMENT ONLY APPLIES TO MODEL NUMBERS
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 2007 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 2000 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.
EMISSIONS PARTS LIST
Emissions parts vary from product to product. Your emissions control system warranty
applies to any of the following components that may be included on your product:
MANUFACTURER’S WARRANTY COVERAGE:

system).
OWNER’S WARRANTY RESPONSIBILITIES
(a) As the non-road or small off-road engine owner, you are responsible for
the performance of the required maintenance listed in your operator’s manual.
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
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.
(ii) Air/fuel ratio feedback and control system.
(iii) Cold start enrichment system.
(iv) Fuel Tank.
(2) Air Induction System
(i) Controlled hot air intake system.
(ii) Intake manifold.

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 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.
If you have any questions regarding your warranty rights and responsibilities, you
should contact a Techtronic Industries North America, Inc., Customer Representa-
tive at 1-800-860-4050.

DEFECT WARRANTY COVERAGE REQUIREMENTS:
(a) The warranty period begins on the date the engine or equipment is delivered to
an ultimate purchaser.
(6) Catalyst or Thermal Reactor System
(i) Catalytic converter.
(b) General Emissions Warranty Coverage. Techtronic Industries North America,
Inc., warrants to the ultimate purchaser and each subsequent purchaser that your
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
applicable regulations for a period of two years from the date the non-road or small
off-road engine is purchased by the initial purchaser.
(ii) Thermal reactor.
(iii) Exhaust manifold.
(7) Particulate Controls
(i) Traps, filters, precipitators, and any other device used to capture particulate
emissions.
(8) Miscellaneous Items Used in Above Systems
(i) Electronic controls.
(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
Maintenance Schedule and Warranty Parts List set forth below is warranted for two
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.
Techtronic Industries North America, Inc., will furnish with each new engine written
instructions for its maintenance and use by the owner.
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.
