GENERAL SAFETY RULES
� Do not touch area around the muffler or cylinder of the
unit, these parts get hot from operation.
 Always stop the engine and remove the spark plug wire
before making any adjustments or repairs except for
carburetor adjustments. Wear your protective equipment
and observe all safety instructions. When the unit is turned
off, make sure the cutting attachment has stopped before
setting the unit down.
 Inspect the unit before each use for loose fasteners, fuel
leaks, etc. Replace any damaged parts before use.
 The string head or blade will rotate during carburetor
adjustments.
 It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness, and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking, and work practices
are all thought to contribute to the development of these
symptoms. It is presently unknown what, if any, vibrations
or extent of exposure may contribute to the condition.
There are measures that can be taken by the operator to
possibly reduce the effects of vibration:
a) Keep your body warm in cold weather. When operating the unit wear gloves to keep hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
b) After each period of operation, exercise to increase
blood circulation.
c) Take frequent work breaks. Limit the amount of
exposure per day.
d) Keep the tool well maintained, fasteners tightened,
and worn parts replaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician about
these symptoms.
 Mix and store fuel in a container approved for gasoline.
� Mix fuel outdoors where there are no sparks or flames.
Wipe up any fuel spillage. Move 30 ft. away from refueling
site before starting engine. Slowly remove the fuel cap
after stopping engine. Do not smoke when refueling.
 Stop the engine and allow to cool before refueling or
storing the unit.
 Allow the engine to cool; empty the fuel tank and secure
the unit from moving before transporting in a vehicle.
WARNING:
Read and understand all instructions. Failure to follow all
instructions listed below may result in electric shock, fire
and/or serious personal injury.
READ ALL INSTRUCTIONS

before using this product. Follow all safety instructions.
Failure to follow all safety instructions listed below, can
result in serious personal injury.
 Do not allow children or untrained individuals to use this
unit.
 Never start or run the engine in a closed or poorly ventilated area; breathing exhaust fumes can kill.
 Clear the work area before each use. Remove all objects
such as rocks, broken glass, nails, wire, or string which
can be thrown or become entangled in the cutting line
or blade.
 Wear safety glasses or goggles that are marked to comply
with ANSI Z87.1 standard when operating this product.
 Wear heavy, long pants, boots, and gloves. Do not wear
loose fitting clothing, short pants, sandals, or go barefoot.

SPECIFIC SAFETY RULES
SPECIFIC SAFETY RULES FOR TRIMMER
USE
 Replace any blade that has been damaged. Always make
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.
 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.
 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 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 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.
 Never cut any material over 1/2 in. diameter.
 Always wear the shoulder harness when using the brushcutter 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.
 Never use the brushcutter with the blade located 30 in.
or more above the ground level.
 Replace string head if cracked, chipped, or damaged
in any way. Be sure the string head or blade is properly
installed and securely fastened. Failure to do so can cause
serious injury.
 Make sure all guards, straps, deflectors, and handles are
properly and securely attached.
 Use only the manufacturer’s replacement string in the
cutting head. Do not use any other cutting attachment.
To install any other brand of replacement string or 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.
SPECIFIC SAFETY RULES FOR BRUSHCUTTER 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.
 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.

WARNING:
WARNING:
Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is
sufficient to inflict serious injury.
Do not use any attachments or accessories not recommended by the manufacturer of this tool. The use of
attachments or accessories not recommended can result
in serious personal injury.
WARNING:
Always wear safety goggles or safety glasses with side
shields when operating tools. Failure to do so could
result in objects being thrown into your eyes, resulting in
possible serious injury.

OPERATION
FUELING AND REFUELING THE TRIMMER
WARNING:
FUEL MIXTURE
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 2-cycle engine oil at 2.6 oz. per gallon
(US).
Do not use automotive oil or 2-cycle outboard oil.
DO NOT mix quantities larger than usable in a 30 day
period.
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
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 comfortable 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.

grass while running engine at full throttle.
 Run engine at full throttle.
 Tap the spool retainer on ground to advance string. The
string advances each time the spool retainer is tapped.
Do not hold the spool retainer on the ground.
BEST CUTTING
AREA
NOTE: The line trimming cut-off blade on the grass deflector
will cut the line to the correct length.
NOTE: If the string is worn too short you may not be able to
advance the string by tapping it on the ground. If so, stop
the engine, and manually advance the string.

DANGEROUS
CUTTING AREA
TO ADVANCE THE CUTTING LINE MANUALLY
 Stop the engine.
 Push the spool retainer down while pulling on string(s) to
manually advance the string.
CUTTING TIPS
See Figures 16 -17.
 Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 15.)
 Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
 The curved shaft trimmer cuts when passing the unit from
right to left. The straight shaft trimmer cuts when passing
the unit from left to right. This will avoid throwing debris at
the operator. Avoid cutting in the dangerous area shown
in illustration.
 Use the tip of string to do the cutting; do not force string
head into uncut grass.
 Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear string rapidly.
 Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the string.

glass, rocks, concrete, fencing, wire, wood, metal, etc.
 Never use blades near sidewalks, fencing, posts, buildings or other immovable objects.
 Never use a blade after hitting a hard object without first
inspecting it for damage. Do not use if any damage is
detected.
 The unit is used as a scythe, cutting from the right to the
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.
See Figures 19 - 20.
Hold the brushcutter with your right hand on the rear handle
and the your hand on the “J” Barrier Handle. Keep a firm
grip with both hands while in operation. Brushcutter should
be held at a comfortable position with the rear handle about
hip height. Maintain your grip and balance on both feet.
Position yourself so that you will not be drawn off balance
by the kickback reaction of the cutting blade.
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
PROPER
OPERATING
POSITION
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 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 occur 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.
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
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 ensure 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
 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
kickback reaction of the cutting blade.

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 offroad 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 diagnosis, 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 nonexempted 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.

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.
This product’s emissions control system is 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 the 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 Techtronic Industries North America, Inc.
(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 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 Representative 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.
(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.
(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 warranty 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.
