  Failure to follow all safety instructions, 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. 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.

• 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, 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.

• 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. 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.

• 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 recommended or equivalent replacement line in the cutting head. Do not use any other cutting attachment.
  To install any other type 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 BRUSH CUTTER AND BLADE USE

• Brush cutter 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 brush cutter unless the brush cutter guard is firmly secured in place and in good condition.

• Use heavy gloves when operating the brush cutter 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 Tri-Arc® blade intended for use on this brush cutter. Do not use any other blade. To install any other brand blade or cutting head to this brush cutter 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 brush cutter 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 brush cutter 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.
