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.
Do not start or operate the engine in a conned space,
building, near open windows, or in other unventilated
space where dangerous carbon monoxide fumes can collect. Carbon monoxide, a colorless, odorless, and extreme-
ly dangerous gas, can cause unconsciousness or death.
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 fatigue,
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.
Never operate this unit on the operator’s left side.
Secure long hair above shoulder level to prevent entan-
glement in moving parts.
Keep all bystanders, children, and pets at least
50 ft. (15 m) away. Bystanders should be encouraged to
wear eye protection. If you are approached, stop the en-
gine 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, upset, 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.
Do not use on a ladder, rooftop, tree, or other unstable
support. Stable footing on a solid surface enables better
control of the unit in unexpected situations.
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 muer 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.
Never use blades, ailing devices, wire, or rope on trim-
mer attachment. Never use ailing devices, wire, or rope
on any attachment.
The cutting attachment should never rotate at idle during
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 include
tingling, numbness, and blanching of the ngers, 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 eects of vibration:
a) Keep your body warm in cold weather. When operat-
ing the unit wear gloves to keep hands and wrists
warm. It is reported that cold weather is a major fac-
tor 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 physician
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. (9 m) away from
refueling site before starting engine. Slowly remove the fuel
cap after stopping engine. Do not smoke when refueling.
Safety Rules
5
Stop the engine and allow to cool before refueling or
storing the unit.
Allow the engine to cool; empty the fuel tank into a con-
tainer approved for fuel and secure the unit from moving
before transporting in a vehicle.
Specific Safety Rules
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 o make sure the cutting attachment has stopped before the unit is set down.
This product is intended for infrequent use by homeown-
ers and other occasional users for such general applications as trimming light and heavy vegetation, etc. It is
not intended for prolonged use. Prolonged periods of
operation can cause circulatory problems in the user’s
hands due to vibration. For such use, it may be appropriate to use a product having an anti-vibration feature.
Specific Safety Rules for Trimmer Use
Inspect before use. Replace damaged parts. Make sure
fasteners are in place and secure. Check for fuel leaks.
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, deectors, and handles are
properly and securely attached.
Use only recommended or equivalent replacement line
in the cutting head. Do not use any other cutting attach-
ment. To install any other brand of replacement line or
cutting head to this string trimmer can result in serious
personal injury. Never use, for example, wire or wire-
rope, which can break o and become a dangerous
projectile.
Never operate unit without the grass deector in place
and in good condition.
Maintain a rm 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
Brushcutter blades coast after throttle trigger is released
or engine is stopped. Keep the rotating blade in thicker
weeds or pulpy stalks until the blade completely stops.
Do not operate the brushcutter unless the brushcutter
guard is rmly 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 rotat-
ing.
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.
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 recommended or equivalent replacement 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 blade is suited for cutting thicker weeds or pulpy
stalks only. Do not use for any other purpose. Never use
the 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 dicult 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 brush-
cutter and adjust to a comfortable operating position.
Maintain a rm 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.
Save these instructions. Refer to them frequently and use
them to instruct others who may use this tool. If you loan
someone this tool, loan them these instructions also.

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 dicult 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.

California Proposition 65 Warning Information
WHAT IS THIS WARNING?
You may see a product for sale that has a warning label like the following:
WARNING: CANCER AND REPRODUCTIVE HARM—WWW.P65WARNINGS.CA.GOV.
WHAT IS PROP 65?
Prop 65 applies to any company operating in California, selling products in California, or manufacturing products that
may be sold in or brought into California. It mandates that the Governor of California maintain and publish a list of chemicals known to cause cancer, birth defects, and/or other reproductive harm. The list, which is updated annually, includes
hundreds of chemicals found in many everyday items. The purpose of Prop 65 is to inform the public about exposure to these
chemicals.
Prop 65 does not ban the sale of products containing these chemicals but instead requires warnings on any product, product
packaging, or literature with the product. Moreover, a Prop 65 warning does not mean that a product is in violation of any
product safety standards or requirements. In fact, the California government has claried that a Prop 65 warning “is not the
same as a regulatory decision that a product is ‘safe’ or ‘unsafe.’” Many of these chemicals have been used in everyday products for years without documented harm. For more information, go to https://oag.ca.gov/prop65/faqs-view-all.
A Prop 65 warning means that a company has either (1) evaluated the exposure and has concluded that it exceeds the “no signicant risk level”; or (2) has chosen to provide a warning based on its understanding about the presence of a listed chemical
without attempting to evaluate the exposure.
DOES THIS LAW APPLY EVERYWHERE?
Prop 65 warnings are required under California law only. These warnings are seen throughout California in a wide range of
settings, including but not limited to restaurants, grocery stores, hotels, schools, and hospitals, and on a wide variety of products. Additionally, some online and mail order retailers provide Prop 65 warnings on their websites or in catalogs.
HOW DO THE CALIFORNIA WARNINGS COMPARE TO FEDERAL LIMITS?
Prop 65 standards are often more stringent than federal and international standards. There are various substances that require
a Prop 65 warning at levels that are far lower than federal action limits. For example, the Prop 65 standard for warnings for
lead is 0.5 μg/day, which is well below the federal and international standards.
WHY DON’T ALL SIMILAR PRODUCTS CARRY THE WARNING?
• Products sold in California require Prop 65 labelling while similar products sold elsewhere do not.
• A company involved in a Prop 65 lawsuit reaching a settlement may be required to use Prop 65 warnings for its products,
but other companies making similar products may have no such requirement.
• The enforcement of Prop 65 is inconsistent.
• Companies may elect not to provide warnings because they conclude that they are not required to do so under Prop 65; a
lack of warnings for a product does not mean that the product is free of listed chemicals at similar levels.
WHY DOES TORO INCLUDE THIS WARNING?
Toro has chosen to provide consumers with as much information as possible so that they can make informed decisions about
the products they buy and use. Toro provides warnings in certain cases based on its knowledge of the presence of one or more
listed chemicals without evaluating the level of exposure, as not all the listed chemicals provide exposure limit requirements.
While the exposure from Toro products may be negligible or well within the “no signicant risk” range, out of an abundance
of caution, Toro has elected to provide the Prop 65 warnings. Moreover, if Toro does not provide these warnings, it could be
sued by the State of California or by private parties seeking to enforce Prop 65 and subject to substantial penalties.
