Introduction
General Safety Rules
WARNING:
Read and understand all instructions. Failure to follow all instructions may result in electric shock, fire
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 confined space,
building, near open windows, or in other unventilated
space where dangerous carbon monoxide fumes can collect. Carbon monoxide, a colorless, odorless, and extremely 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 fitting 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.
 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. 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, upset, 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.
Safety Rules
 Do not use on a ladder or 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 muffler 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, flailing devices, wire, or rope on trimmer attachment. Never use flailing 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 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 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 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.
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 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.
Specific Safety Rules
 This product is intended for infrequent use by homeowners 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, deflectors, and handles are
properly and securely attached.
 Use only the manufacturer’s replacement line in the
cutting head. Do not use any other cutting attachment.
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 off and become a dangerous projectile.
 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 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 firmly 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 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.
 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 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 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 cut any material over 1/2 in. diameter.
 Always wear the shoulder harness when using the brushcutter 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.
 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.

Blade Thrust
Exercise extreme caution when using a blade attachment
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 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.

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline,
petroleum-based products, penetrating lubricants,
etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which
can result in serious personal injury.
NOTICE:
Keeping air intake vents free of grass and debris
prevents motor overheating and possible failure.
Servicing the Product
Check and tighten all fasteners. If any part is damaged or
lost, repair it or replace it.
Checking the Fuel Cap, Tank, and Lines
WARNING:
Check for fuel leaks. A leaking fuel cap, tank,
or lines are a fire hazard and must be replaced
immediately. If you find any leaks, correct the
problem before using the product. Failure to do
so could result in a fire that could cause serious
personal injury.
The fuel cap contains a non-serviceable filter and check
valve. A clogged fuel filter causes poor engine performance.
If performance improves when the fuel cap is loosened,
the check valve may be faulty or the filter may be clogged.
Replace the fuel cap if necessary.
