SPECIFIC SAFETY RULES  
A coasting blade can cause injury while it continues  
SPECIFIC SAFETY RULES FOR TRIMMER  
USE  
Inspect before use. Replace damaged parts. Make sure  
to spin after the engine is stopped or throttle trigger  
released. Maintain proper control until the blade has  
completely stopped rotating.  
fasteners are in place and secure. Check for fuel leaks.  
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.  
Replace string head if cracked, chipped, or damaged  
in any way. Be sure the string head or blade is properly  
installedandsecurelyfastened.Failuretodosocancause  
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 use, for example, wire or wire-rope, which  
can break off and become a dangerous projectile.  
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 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  
guard is firmly secured in place and in good condition.  
Never cut any material over 1/ꢀ in. diameter.  
Use heavy gloves when operating the brushcutter and  
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.  
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.

OPERATION  
OXYGENATED FUELS  
FUELING AND REFUELING THE TRIMMER  
Some conventional gasolines are blended with alcohol or an  
ether compound. These gasolines are collectively referred  
to as oxygenated fuels. To meet clean air standards, some  
areas of the United States and Canada use oxygenated fuels  
to help reduce emissions.  
FUEL MIXTURE  
This product is powered by a ꢀ-cycle engine and requires  
pre-mixing gasoline and ꢀ-cycle lubricant. Pre-mix unleaded  
gasoline and ꢀ-cycle engine lubricant in a clean 1 gallon  
container approved for gasoline.  
If using an oxygenated fuel, make sure it is unleaded and  
meets the minimum octane rating requirements. Before using

PROPER  
OPERATInG  
POSITIOn  
WARNING:  
Always position the unit on the operator’s right side. The  
use of the unit on the operator’s left side will expose  
the user to hot surfaces and can result in possible burn  
injury.  
WARNING:  
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 lubricant dripping from the muffler.

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.

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.

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

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
