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, 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. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury.
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. 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 blade or saw chain.
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.
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.
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 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.
Store fuel in a container approved for gasoline. Stop the engine and allow to cool before refueling or
storing the unit.

GENERAL SAFETY RULES
Allow the engine to cool; empty the fuel tank 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
SPECIFIC SAFETY RULES
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.
Never use blades, flailing devices, wire, or rope on trimmer
attachment.
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.
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.
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 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.
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 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.

Place the feeler gauge under each rocker arm and measure
the gap. The gap should be between .006 in. (0.15 mm) and .008 in. (0.20 mm) for both rocker arms.
NOTE: Use a standard automotive feeler gauge. The .006
in. (0.15 mm) feeler gauge should slide between the rocker arm and valve stem with a slight amount of resistance but without binding. The 0.008 in. (0.20 mm) feeler gage should not slide between the rocker arms and the cam lobes — it should be held tight.
If the valve clearance is not between .006 in. (0.15 mm) and
.008 in. (0.20 mm), the clearance should be adjusted as follows:
• While holding a wrench on the flats of the adjusting
nut with one hand, loosen the retaining nut with a second wrench as shown. Take care not to loosen the stud.
• Rotate the adjusting nut until it touches the feeler gauge.
Once the gap setting is correct, hold the wrench on the flats of the adjusting nut and retighten the retaining nut securely.
Adjust the second rocker arm, if necessary. Replace the rocker arm cover and screw; tighten securely.
Replace the top engine cover and screw; tighten securely.
WARNING:
Ensure all engine cover and all engine parts are completely and properly reassembled before starting engine. Failure to correctly reassemble engine may result in serious injury or property damage.

HIGH ALTITUDE ENGINE OPERATION
Please have an authorized service center adjust this engine if it is to be run above 2000 feet. Failure to do so may result in poor engine performance, spark plug fouling, hard starting, and increased emissions. Carburetor adjustment by an autho­rized service center will improve performance and allow that this engine meets EPA (Environmental Protection Agency) and California ARB (Air Resources Board) emission standards. An engine adjusted for high altitudes can not be run at 2000 feet or lower. In doing so, the engine will overheat and cause seri­ous engine damage. Please have an authorized service center restore high altitude modified engines to the original factory
specification before operating below 2000 feet.
