SPECIFIC SAFETY RULES  
Replace any blade that has been damaged. Always make  
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.  
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.  
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.  
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.  
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 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  
Never cut any material over 1/2 in. diameter.  
guard is firmly secured in place and in good condition.  
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.  
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 use the brushcutter with the blade located 30 in.  
or more above the ground 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.

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 gaso-  
line and 2-cycle engine oil in a clean 1 gallon container ap-  
proved 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.  
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.

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  
Fig. 16  
NOTE: The line trimming cut-off blade on the grass deflector  
will cut the line to the correct length.  
STRAIGHT SHAFT TRIMMER  
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.)  
BEST CUTTING  
AREA  
DIRECTION OF  
ROTATION  
Keep the trimmer tilted toward the area being cut; this is  
the best cutting area.  
Fig. 17  
Thecurvedshafttrimmercutswhenpassingtheunitfrom  
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.  
STRAIGHT SHAFT  
TRIMMER LINE TRIMMING  
CUT-OFF BLADE  
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.  
CURVED SHAFT TRIMMER

BLADE  
Avoidtreesandshrubs.Treebark,woodmoldings,siding,  
and fence posts can easily be damaged by the string.  
GRASS DEFLECTOR LINE TRIMMING CUT-OFF  
BLADE  
See Figure 18.  
Fig. 18  
The trimmer is equipped with a line trimming cut-off blade  
on the grass deflector. For best cutting, advance string until  
it is trimmed to length by the cut-off blade. Advance the  
string whenever you hear the engine running faster than  
normal, or when trimming efficiency diminishes. This will  
maintain best performance and keep the string long enough  
to advance properly.

OPERATION  
Inspect and clear the area of any hidden objects such as  
OPERATING THE BRUSHCUTTER  
See Figures 19 - 20.  
glass, rocks, concrete, fencing, wire, wood, metal, etc.  
Never use blades near sidewalks, fencing, posts, build-  
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.  
ings 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.  
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.  
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  
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.  
WARNING:  
To avoid burns from hot surfaces, never operate unit with  
the bottom of the engine above waist level.

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  
kickback reaction of the cutting blade.

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.

(7) Particulate Controls  
(i) Traps, filters, precipitators, and any other device used to capture particulate

(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.
