SAFETY WARNINGS FOR GAS UNITS

WARNING: Gasoline is highly flammable, and its vapors can explode if ignited. Take the following precautions:

•Store fuel only in containers specifically designed and approved for the storage of such materials.

•Always stop the engine and allow it to cool before filling the fuel tank. Never remove the fuel tank cap or add fuel when the engine is hot. Always loosen the fuel tank cap slowly to relieve any pressure in the tank before fueling. Do not smoke.

•Always add fuel in a clean, well-ventilated outdoor area where there are no sparks or flames. Do not smoke.

•Never operate the unit without the fuel cap securely in place.

•Avoid creating a source of ignition for spilled fuel. Wipe up any spilled fuel from the unit immediately before starting the engine. Move the unit at least 30 feet (9.1 m) from the fueling source and site before starting the engine. Do not smoke.

•Never start or run the unit inside a closed room or building. Breathing exhaust fumes can kill. Only operate this unit in a well-ventilated outdoor area.

WHILE OPERATING

•Wear safety glasses or goggles that meet ANSI Z87.1 standards and are marked as such. Wear ear/hearing protection when operating this unit. Wear a face or dust mask if the operation is dusty.

•Wear heavy long pants, boots, gloves and a long sleeve shirt. Do not wear loose clothing, jewelry, short pants, sandals or go barefoot. Secure hair above shoulder level.

•The cutting attachment shield must always be in place while operating the unit as a trimmer. Do not operate unit without both trimming lines extended, and the proper line installed. Do not extend the trimming line beyond the length of the shield.

RULES FOR SAFE OPERATION

•This unit has a clutch. The cutting attachment remains stationary when the engine is idling. If it does not, have the unit adjusted by an authorized service technician.

•Adjust the handle to your size in order to provide the best grip.

•Be sure the cutting attachment is not in contact with anything before starting the unit.

•Use the unit only in daylight or good artificial light.

•Avoid accidental starting. Be in the starting position whenever pulling the starter rope. The operator and unit must be in a stable position while starting. Refer to Starting/Stopping Instructions.

•Always hold the unit with both hands when operating. Keep a firm grip on both handles or grips.

•Keep hands, face, and feet at a distance from all moving parts. Do not touch or try to stop the cutting attachment when it rotates.

•Do not touch the engine, gear housing or muffler. These parts get extremely hot from operation, even after the unit is turned off.

•Do not operate the engine faster than the speed needed to cut, trim or edge. Do not run the engine at high speed when not cutting.

•Always stop the engine when cutting is delayed or when walking from one cutting location to another.

•If you strike or become entangled with a foreign object, stop the engine immediately and check for damage. Do not operate before repairing damage. Do not operate the unit with loose or damaged parts.

•Keep unit clean of vegetation and other materials. They may become lodged between the cutting attachment and shield.

•To reduce fire hazard, replace a faulty muffler and spark arrestor. Keep the engine and muffler free from grass, leaves, excessive grease or carbon build up.

WHILE OPERATING WITH CUTTING BLADE

•Read and understand all safety warnings before operating this unit.

•Always use the shoulder harness when using the brush blade accessory.

•Keep the D-handle between the operator and cutting attachment or blade at all times.

•NEVER cut when the cutting blade is 30 inches (76 cm) or more above the ground level.

•Blade thrust may occur when the spinning blade contacts an object that it does not immediately cut. Blade thrust can be violent enough to propel the unit and/or operator in any direction, possibly causing a loss of control. 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 operation with the brush blade, do not cut anything thicker than 1/2 inch or a violent kickback could occur.

•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 the throttle trigger is released. Maintain proper control until the blade has completely stopped rotating.

•Do not run the unit at high speed when not cutting.

•If you strike or become entangled with a foreign object, stop the engine immediately and check for damage. Have any damage repaired before attempting further operations. Do not operate unit with a bent, cracked or dull blade. Discard blades that are bent, warped, cracked or broken.

•Do not sharpen the cutting blade. Sharpening the blade can cause the blade tip to break off while in use. This can result in severe personal injury. Replace the blade.

•Do not use the cutting blade for edging or as an edger; severe personal injury to yourself or others may incur. Use the cutting blade only for the purpose described in this manual.

•Stop the engine IMMEDIATELY if you feel excessive vibration. Vibration is a sign of trouble. Inspect thoroughly for loose nuts, bolts or damage before continuing. Repair or replace affected parts as necessary.

AFTER USE

•Clean cutting blades with a household cleaner to remove any gum buildup. Oil the blade with machine oil to prevent rust.

•Lock up and store the cutting blade in an appropriate area to protect the blade from unauthorized use or damage.

OTHER SAFETY WARNINGS

•Never store a fueled unit inside a building where fumes may reach an open flame or spark.

•Allow the engine to cool before storing or transporting. Be sure to secure the unit while transporting.

•Store the unit in a dry area, locked up or up high to prevent unauthorized use or damage, out of the reach of children.

•Never douse or squirt the unit with water or any other liquid. Keep handles dry, clean and free from debris. Clean after each use, see Cleaning and Storage instructions.

O-Ring

Oil Fill

Hole

Fig. 18

Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol or MTBE (ether). Alcoholblended fuel absorbs water. As little as 1% water in the fuel can make fuel and oil separate or form acids when stored. Use fresh fuel (less than 30 days old), when using alcohol-blended fuel.

Using Blended Fuels

If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:

•Always use fresh unleaded gasoline

•Use the fuel additive STA-BIL® or an equivalent

•Drain tank and run the engine dry before storing unit

USING FUEL ADDITIVES

WARNING: Add fuel in a clean, well ventilated outdoor area. Wipe up any spilled fuel immediately. Avoid creating a source of ignition for spilt fuel. Do not start the engine until fuel vapors dissipate.

WARNING: Gasoline is extremely flammable. Ignited vapors may explode. Always stop the engine and allow it to cool before filling the fuel tank. Do not smoke while filling the tank. Keep sparks and open flames at a distance from the area.

OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

WARNING: Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating this unit.

Before operating the unit, stand in the operating position (Fig. 23). Check for the following:

• The operator is wearing eye protection and proper clothing

• With a slightly-bent right arm, the operator’s right hand is holding the shaft grip

• The operator’s left arm is straight, the left hand holding the assist handle	Fig. 23

•The unit is at waist level

•The cutting attachment is parallel to the ground and easily contacts the grass without the need to bend over

ADJUSTING TRIMMING LINE LENGTH

WARNING: Do not remove or alter the line cutting blade assembly. Excessive line length will make the clutch overheat. This may lead to serious personal injury or damage to the unit.

The Bump Head™ cutting attachment allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting attachment on the ground (Fig. 24) while operating the trimmer at high speed.

NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.

Each time the head is bumped, about 1 inch (25.4 mm) of trimming line is released. A blade in the cutting attachment shield will cut the line to the proper length if excess line is released.

For best results, tap the Bump Head™ on bare ground or hard soil. If line release is attempted in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.

NOTE: Do not rest the Bump Head™ on the ground while the unit is running. Some line breakage will occur from:

• Entanglement with foreign matter

• Normal line fatigue

• Attempting to cut thick, stalky weeds

• Forcing the line into objects such as walls or fence posts

TIPS FOR BEST TRIMMING RESULTS

Fig. 24

• For best trimming results, operate unit at full throttle.

• Keep the cutting attachment parallel to the ground.

• Do not force the cutting attachment. Allow the tip of the line to do the cutting, especially along walls. Cutting with more than the tip will reduce cutting efficiency and may overload the engine.

• Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag.

• Cutting from left to right improves the unit's cutting efficiency. Clippings are thrown away from the operator.

• Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forward-backward or side-to-side motion. Cutting shorter lengths produces the best results.

• Trim only when grass and weeds are dry.

• The life of your cutting line is dependent upon proper adherence of explained

trimming techniques, what vegetation is cut, and where vegetation is cut.
For example, the line will wear faster when trimming against a foundation wall as
opposed to trimming around a tree.
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all vegetation around trees, posts,
fences and more.	Fig. 25
Rotate the whole unit so that the cutting attachment is at a 30° angle to the ground (Fig. 25).

USING THE CUTTING BLADE

WARNING: Always wear eye, hearing, foot, body protection and the shoulder strap to reduce the risk of injury when operating this unit.

WARNING: Do not use the cutting blade for edging or as an edger. Severe personal injury to yourself or others can result.

Before operating the unit with the cutting blade, stand in the operating position (Fig. 23). Refer to Holding the Trimmer.

OPERATING INSTRUCTIONS

Cutting Blade Operating Tips

WARNING: Blade thrust may occur when the spinning blade contacts an object that it does not immediately cut. Blade thrust can be violent enough to cause the unit and/or operator to be propelled in any direction, and possibly 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.

WARNING: The blade continues to spin after the engine is turned off. The coasting blade can seriously cut you if accidentally touched.

To establish a rhythmic cutting procedure:

• Plant feet firmly, comfortably apart.

• Bring the engine to full throttle before entering the material to be cut. At full throttle the blade has maximum cutting power and is less likely to bind, stall or cause blade thrust (which can result in serious personal injury to the operator or others).

• Cut while swinging the upper part of your body from left to right.

• Always release the throttle trigger and allow the engine to return to idle speed when not cutting.

• When you are finished, always unsnap the unit from the harness before taking off
		Fig. 26
the harness.

•Swing the unit in the opposite direction as the blade spins, which increases the cutting action.

•After the return swing, move forward to the next area to be cut plant your feet again.

•The cutting blade is designed with a second cutting edge. You can use it by removing the blade, turning it upside down, and reinstalling it.

To reduce the chance of material wrapping around the blade, follow these steps:

WARNING: Do not sharpen the cutting blade. Sharpening the blade can cause the blade tip to break off while in use. This can result in severe personal injury to yourself or others. Replace the blade.

•Cut at full throttle

•Swing the unit into material to be cut from your left to your right (Fig. 26)

•Avoid the material just cut as you make the return swing

WARNING: Do not clear away any cut material with the engine running or blade turning. To avoid serious personal injury, turn off the engine. Allow the blade to stop before removing materials wrapped around the blade shaft.

•Ne démarrez jamais l’appareil sans avoir bien revissé le bouchon du réservoir d’essence.

•Évitez tout ce qui pourrait enflammer le carburant renversé. L’essence s’étant échappée de l’appareil doit être essuyée immédiatement avant de démarrer l'appareil. Éloignez l’appareil d’au moins 9,1 m (30 pieds) du site et de la source du carburant avant de démarrer le moteur. Ne fumez pas.

CONSIGNES DE SÉCURITÉ

•L'appareil ne doit pas être démarré ou utilisé à l'intérieur d'un espace ou d’un bâtiment clos. Inhaler les fumées du pot d’échappement peut provoquer la mort. Cet appareil doit fonctionner uniquement en extérieur, dans une zone bien aérée.

PENDANT L'UTILISATION DE L'APPAREIL

•Portez des lunettes de sécurité conformes aux normes ANSI Z87.1 ainsi que des protège-oreilles durant l'utilisation de l'appareil. Portez un masque facial ou antipoussières si vous travaillez dans un lieu poussiéreux.

•Portez des pantalons épais et longs, des bottes, des gants et une chemise à manches longues. Ne marchez pas pieds nus et évitez les vêtements lâches, bijoux, pantalons courts et sandales. Relevez les cheveux au-dessus des épaules.

•Le protecteur d'accessoire de coupe doit toujours être en place lors de l'utilisation de l'appareil. Ne faites pas marcher l'appareil sans que les deux fils soient bien déployés, en supposant qu'un fil approprié a été installé. Assurez-vous que le fil ne dépasse pas le protecteur de sécurité.

•Cet appareil est muni d'un embrayage. L'accessoire de coupe reste stationnaire lorsque le moteur est au ralenti. Si ce n'est pas le cas, faites régler l'appareil par un technicien agréé.

•Ajustez la poignée selon votre taille pour mieux l'agripper.

•N'utilisez l'appareil qu'en plein jour ou avec un bon éclairage artificiel.

•Évitez tout démarrage accidentel. Mettez-vous en position de démarrage chaque fois que vous tirez sur la corde de démarrage. L'opérateur et l'appareil doivent tous deux être en position stable à ce momentlà. Voir les Instructions de démarrage et d'arrêt.

•Ne vous étirez pas. Tenez-vous toujours bien sur vos pieds en position d'équilibre.

•Tenez toujours l'appareil des deux mains lorsque vous le faites marcher. Agrippez fermement les poignées avant et arrière.

•Gardez les mains, le visage et les pieds éloignés des pièces mobiles. Ne touchez pas et n'essayez pas d'arrêter l'accessoire de coupe en rotation.

•Ne touchez pas le moteur, le boîtier d'engrenages ni le silencieux. Ces pièces deviennent très chaudes à l'utilisation. Elles restent chaudes brièvement après l'arrêt.

•Servez-vous des outils appropriés. N'utilisez cet outil que pour son usage prévu.

•Ne faites pas fonctionner le moteur à un régime plus élevé que nécessaire pour couper, tailler ou faire les bordures. Ne faites pas tourner le moteur à haut régime si vous ne vous faites pas de coupe.

•Arrêtez toujours le moteur lorsque vous suspendez la coupe ou lorsque vous vous déplacez d'un lieu de travail vers un autre.

•Si vous heurtez un corps étranger ou que celui-ci est happé, arrêtez le moteur immédiatement et vérifiez que rien n'a été endommagé. Ne faites pas fonctionner avant réparation des dommages. Ne faites pas marcher l'appareil si les pièces sont desserrées ou endommagées.

•Arrêtez et éteignez le moteur dans les cas suivants: entretien, réparation ou changement d'accessoires ou autres.

•N'utilisez que des pièces de équipement original rechange et accessoires d’origine du fabricant pour cet appareil. Elles sont disponibles auprès de votre concessionnaire agréé. L'utilisation de pièces ou accessoires autres que ceux de éqiupement original peut causer des blessures graves, endommager l’appareil et annuler sa garantie.

•Gardez l'appareil exempt d'accumulation de végétation ou autres matières. Celles-ci peuvent rester logées entre l'accessoire de coupe et le protecteur.

•Afin de diminuer les risques d'incendie, remplacez tout

silencieux ou pare-étincelles défectueux et conservez le moteur et le silencieux exempts d'herbe, de feuilles et d'accumulation excessive de graisse ou de carbone.

PENDANT L'UTILISATION DE LA LAME DE COUPE

•Prenez soin de bien lire et comprendre tous les avertissements de sécurité avant de faire fonctionner cet appareil.

•Portez toujours le harnais d'épaule lorsque vous utilisez la lame à broussailles.

•Maintenez toujours la poignée entre l'opérateur et l'accessoire de coupe ou la lame.

•Ne coupez jamais si la lame de coupe est à plus de 76 cm (30 po) au-dessus du sol.

•Lorsque la lame pivotante frappe un objet qu'elle ne peut pas couper, elle donne un coup brusque qui peut pousser violemment l'opérateur et l'appareil vers n'importe quelle direction et faire perdre le contrôle de l'appareil. Ceci peut se produire à l'improviste si la lame s'accroche, cale ou se coince. Cela est plus susceptible de se produire dans les endroits où il est difficile de voir ce que l'on coupe.

•Avec une lame à broussailles, ne coupez rien de plus épais que 1,3 cm (1/2 po) au risque de provoquer un recul violent.

•N'essayez pas de toucher ni d'arrêter la lame pendant qu'elle tourne.

•La lame continue de tourner à vide une fois le moteur éteint ou la manette des gaz relâchée et peut causer des blessures graves. Gardez le contrôle jusqu'à ce qu'elle ait complètement arrêté de tourner.

•Ne faites pas tourner l'appareil à haut régime si vous ne faites pas de coupe.

•Si vous heurtez un corps étranger ou que celui-ci est happé, arrêtez le moteur immédiatement et vérifiez que rien n'a été endommagé. Réparez tout dommage éventuel avant de poursuivre le travail. N'utilisez pas l'appareil si la lame est tordue, fendillée ou émoussée. Jetez toute lame tordue, fendillée ou émoussée.

•N'aiguisez pas la lame de coupe car son extrémité risquerait de casser à l'usage et causer des blessures graves. Remplacez-la plutôt.

•Arrêtez le moteur IMMÉDIATEMENT si vous ressentez une vibration excessive car cela indique un problème. Vérifiez soigneusement qu'il n'y a ni écrous ni boulons desserrés, ni aucun dommage avant de continuer. Réparez ou remplacez les pièces affectées au besoin.

APRÈS L'UTILISATION

•Nettoyez la lame de coupe avec un nettoyant ménager pour éliminer toute accumulation de gomme. Lubrifiez la lame avec de l'huile mécanique contre la rouille.

•Verrouillez et rangez la lame de coupe dans un lieu approprié pour éviter toute utilisation indésirable ou des dommages.

AUTRES AVERTISSEMENTS DE SÉCURITÉ

•N'entreposez jamais l'appareil rempli de carburant dans un édifice où les vapeurs peuvent atteindre une source de flammes vives ou d'étincelles.

•Laissez le moteur se refroidir avant de l'entreposer ou de le transporter. Attachez bien l'appareil pendant le transport.

•Rangez l'appareil dans un endroit verrouillé et sec, ou élevé et sec, hors de portée des enfants, pour éviter une utilisation indésirable ou un accident.

•Ne trempez et n'arrosez jamais l'appareil avec de l'eau ou tout autre liquide. Gardez les poignées sèches, propres et exemptes de débris. Nettoyez après chaque usage. Voir les sections Nettoyage et Entreposage.
