with ANSI Z87.1 standards and hearing protection when
operating this unit.
Wear heavy, long pants, boots, and gloves. Do not wear
loose fitting clothing, short pants, sandals, or go barefoot.
Do not wear jewelry of any kind.
Product users on United States Forest Service land,
and in some states, must comply with fire prevention
regulations. This product is equipped with a spark arrestor;
however, other user requirements may apply. Check with
your federal, state, or local authorities.
Never operate this unit on the operator’s left side.
� Secure long hair above shoulder level to prevent
entanglement in moving parts.
� Keep all bystanders, children, and pets at least 50 ft.
(15 m) away. Bystanders should be encouraged to wear
eye protection.
� Do not operate this unit when you are tired, ill, or under
the influence of alcohol, drugs, or medication.
� Do not operate in poor lighting.
� Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance or exposure
to hot surfaces.
� Keep all parts of your body away from any moving
part.
� To avoid hot surfaces, never operate the unit with the
bottom of the engine above waist level.
� 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 oper-
ating 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. (9 m) 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.

OPERATION
ADVANCING TRIMMER CUTTING LINE
String advance is controlled by tapping the string head on
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.
NOTE: The line trimming cut-off blade on the grass
deflector will cut the line to the correct length.
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 by pushing
the spool retainer down while pulling on string(s).
GRASS DEFLECTOR LINE TRIMMING CUT-OFF
BLADE
See Figure 8.
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.

OPERATING THE TRIMMER
See Figure 9.
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 oil dripping from the muffler.

OPERATION
WARNING:
Always hold the string trimmer away from the body keeping clearance between the body and the product. Any
contact with the housing or string trimmer cutting head can
result in burns and/or other serious personal injury.
TRIMMER CUTTING TIPS
See Figures 9 -10.
Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 9.)
Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
The trimmer cuts when passing the unit from right to
left. This will avoid throwing debris at the operator. Avoid
cutting in the dangerous area shown in figure 10.
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 and
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.
EDGER CUTTING TIPS
See Figure 11.
� The edger will edge along sidewalks, driveways, flower
beds, curbs, and similar areas.
� Use the arrow guide on the blade guard to align the blade
with the edging surface.
� Cut at a steady pace. If the blade begins to bog down,
you are edging too fast; slow your pace. Do not force the
blade into ground.
� Light contact of the blade against the sidewalk edge, curb,
etc., is acceptable and will not damage the edger.
� Best appearance is obtained when grass is dry. Avoid
edging in wet soil or wet grass areas or the blade guard
might clog and result in an uneven edge. If the blade
guard becomes clogged, stop the engine, remove the
spark plug wire or disconnect from the power supply,
and remove debris from the blade guard.
ARROW
GUIDE
OPERATING THE EDGER
See Figure 11.
Hold the edger with your right hand on the rear handle and
your left hand on the front handle. The edger should be held
on the right side of the body. Keep a firm grip with both hands
while in operation. The edger should be held at a comfortable
position with the rear handle about hip height.
NOTE: When the attachment is being used on a trimmer
with a gasoline engine, always operate at full throttle. Prolonged cutting at partial throttle will result in oil dripping
from the muffler.

OPERATION
ADJUSTING EDGER BLADE DEPTH
See Figures 12 - 13.
Depth of the cut is determined by the distance from the
bottom of the wheel to the tip of blade.
Stop the engine and remove the spark plug wire or
disconnect from the power source.
Loosen the adjusting knob and move the wheel arm up
to increase the depth and down to decrease the depth.
After adjustment is complete, tighten the adjusting knob
securely.
Replace the spark plug wire or connect to the power
supply and start the unit.
NOTE: Adjust the blade depth from 1/2 in. to 1 in. (1.2 to
2.5 cm) deep initially. Make a shallow cut to test the cutting
depth. If the cutting depth needs adjusting, this should be
done progressively until the desired depth is reached.

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
FEDERAL AND CALIFORNIA EMISSION CONTROL SYSTEMS NON-ROAD AND SMALL
OFF-ROAD ENGINES
The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Techtronic Industries North America, Inc.,
are pleased to explain the Emission Control System Warranty on your non-road or small off-road engine. In California, new 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, 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
parts, and labor.
®
brand outdoor products),
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.
