Introduction
General Safety Rules
WARNING:
Read and understand all instructions. Failure to follow all instructions may result in electric shock, re
and/or serious personal injury.
Read All Instructions
For safe operation, read and understand 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 venti-
lated area; breathing exhaust fumes can kill.
Clear the work area before each use. Remove all objects
such as rocks, broken glass, nails, wire, or loose string
which can be thrown or become entangled in the cutting
line or blade.
Always wear eye protection with side shields marked to
comply with ANSI Z87.1 along with hearing protection
when operating this equipment.
Wear heavy, long pants, long sleeves, boots, and gloves.
Do not wear loose tting clothing, short pants, sandals,
or go barefoot. Do not wear jewelry of any kind.
Heavy protective clothing may increase operator fa-
tigue, which could lead to heat stroke. During weather
that is hot and humid, heavy work should be scheduled
for early morning or late afternoon hours when temperatures are cooler.
Product users on United States Forest Service land,
and in some states, must comply with re 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 en-
tanglement in moving parts.
Keep all bystanders, children, and pets at least
50 ft. away. Bystanders should be encouraged to wear
eye protection. If you are approached, stop the engine
and cutting attachment. In the case of bladed units,
there is the added risk of injury to bystanders from being struck with the moving blade in the event of a blade
thrust or other unexpected reaction of the saw.
Do not operate this unit when you are tired, ill, or under
the inuence of alcohol, drugs, or medication.
Do not operate in poor lighting.
Keep rm footing and balance. Do not overreach. Over-
reaching 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 mufer or cylinder of the
unit, these parts get hot from operation. Contact with
hot surfaces could result in possible serious personal
injury.
Always stop the engine and remove the spark plug wire
before making any adjustments or repairs except for
carburetor adjustments.
Inspect the unit before each use for loose fasteners, fuel
leaks, etc. Replace any damaged parts before use.
The cutting attachment should never rotate at idle dur-
ing normal use. The cutting attachment may rotate at
idle 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 in-
clude tingling, numbness, and blanching of the ngers,
usually apparent upon exposure to cold. Hereditary
factors, exposure to cold and dampness, diet, smok-
ing, 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 condi-
tion, immediately discontinue use and see your physi-
cian about these symptoms.
Mix and store fuel in a container approved for gasoline.
Mix fuel outdoors where there are no sparks or ames.
Wipe up any fuel spillage. Move 30 ft. away from refu-
eling 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 into a
container approved for fuel and secure the unit from
moving before transporting in a vehicle.
Wear your protective equipment and observe all safety
instructions. For units equipped with a clutch, be sure
the cutting attachment stops turning when the engine
idles. When the unit is turned off make sure the cutting
attachment has stopped before the unit is set down.

engine and manually advance the line.
To advance the cutting line manually:
Stop the engine and disconnect the spark plug wire.
Push the knob in while pulling on line(s) to manually
advance the line.
Cutting Tips
See Figures 12 and 13.
1. Avoid hot surfaces by always keeping the tool away
from your body. (Proper operating position is shown in
Figures 9 and 10.)
2. Keep the trimmer tilted toward the area being cut; this
is the best cutting area.
3. 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 gures 12 and 13.
4. Use the tip of string to do the cutting; do not force
string head into uncut grass.
5. Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs and wood may
wear string rapidly.
6. Avoid trees and shrubs. Tree bark, wood moldings, sid-
ing and fence posts can easily be damaged by the string.

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 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 2011 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 three 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 Toro®
brand outdoor products.
MANUFACTURER’S WARRANTY COVERAGE:
This product’s emissions control system is warranted for three 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 1-866-574-9242 (US) or 1-866-574-9243 (Canada).
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 three 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
three 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 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 Authorized Service
Center for no charge until that replacement point is reached.
Techtronic Industries North America, Inc., shall remedy warranty defects at any
authorized Authorized Service Center, including any distribution center that
may be franchised to service the subject engines. Any diagnostic work done at
a 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.
