Inspect the unit before use. Replace damaged parts. Check for fuel leaks. Make sure all fasteners are in place and secure. Replace parts that are cracked, chipped, or damaged in any way. Do not operate the unit with loose or damaged parts.

Carefully inspect the area before starting the unit. Remove all debris and hard or sharp objects such as glass, wire, etc.

Be aware of the risk of injury to the head, hands and feet.

Clear the area of children, bystanders, and pets. At a minimum, keep all children, bystanders, and pets outside a 50 feet (15 m.) radius; there still may be a risk to bystanders from thrown objects. Bystanders should be encouraged to wear eye protection. If you are approached, stop the unit immediately.

Use only 0.105 inch, 2.67 mm diameter original equipment manufacturer replace-ment line. Never use metal-reinforced line, wire or rope. These can break off and become dangerous projectiles.

Squeeze the throttle control and check that it returns automatically to the idle position. Make all adjustments or repairs before using unit.

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.

Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate.

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. Never operate the unit without the fuel cap securely in place. Loosen the fuel tank cap slowly to relieve any pressure in the tank.

Add fuel in a clean, well-ventilated outdoor area where there are no sparks or flames. Remove the fuel cap slowly, and only after the engine stops. Do not smoke while fueling. Wipe up any spilled fuel from the unit immediately.

Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate.

Move the unit at least 30 feet (9.1 m) from the fueling source and site before starting the engine. Do not smoke. Keep sparks and open flames away from the area while adding fuel or operating the unit.

WHILE OPERATING

Never start or run the unit inside a closed room or building. Breathing exhaust fumes can be fatal. Operate this unit only in a well-ventilated outdoor area.

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.

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.

Use the right tool. Only use this tool for its intended purpose.

Do not overreach. Always keep proper footing and balance.

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.

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 J-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.

the unit, do not mix oil with gasoline.

Definition of Blended Fuels

Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol or MTBE (ether). Alcohol-blended 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 60 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.

The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful deposits in the carburetor for up to six (6) months. Add 0.8 oz. (23 ml.) of fuel additive per gallon of fuel according to the instructions on the container. NEVER add fuel additives directly to the unit's gas tank.

FUELING THE UNIT

WARNING: Remove fuel cap slowly to avoid injury from fuel spray. Never operate the unit without the fuel cap securely in place.

1.Remove the fuel cap (Fig. 18).

2.Place the gas container’s spout into the fill hole on the fuel tank (Fig. 18) and fill the tank.

NOTE: Do not overfill the tank.

3.Wipe up any gasoline that may have spilled.

4.Reinstall the fuel cap.

5.Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine.

NOTE: Dispose of the old gasoline in accordance to Federal, State and Local regulations.

tap the cutting

 

attachment on the

 

ground (Fig. 26) while

 

operating the trimmer at

 

high speed.

Fig. 26

 

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

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.

Rotate the whole unit so that the cutting attachment is at a 30° angle to the ground (Fig. 27).

Fig. 27

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. 28). Refer to Holding the Trimmer.

Cutting Blade Operating Tips

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.

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.

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 the harness.

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

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

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.

OPERATING INSTRUCTIONS

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. 29)

• 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

CARBURETOR ADJUSTMENT

The idle speed of the engine is adjustable. An idle adjustment screw is between the air filter cover and the engine starter housing (Fig. 50).

NOTE: Careless adjustments can seriously damage your unit. An authorized service dealer should make carburetor adjustments.

Check Fuel

Old fuel is usually the reason for improper unit performance. Drain and refill the tank with fresh fuel

prior to making any adjustments. Refer to Oil and Fuel Information.

Clean Air Filter

The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict air flow. This is often mistaken for an out of adjustment carburetor. Check the condition of the air filter before adjusting the idle speed screw. Refer to Air Filter Maintenance.

Adjust Idle Speed Screw

WARNING: To prevent serious personal injury, make sure the cutting attachment has stopped rotating before you turn it off and set it down.

If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed screw as follows:

1.Start the engine and let it run at a high idle for a minute to warm up. Refer to Starting/Stopping Instructions.

2.Release the throttle trigger and let the engine idle. If the engine stops, insert a small phillips in between the Air Filter Cover and the Engine Cover (Fig. 50). Turn the idle speed screw in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly.

NOTE: The cutting attachment should not rotate when the engine idles.

3.If the cutting attachment rotates when the engine idles, turn the idle speed screw counterclockwise 1/8 of a turn at a time (as needed), to reduce idle speed.

WARNING: The cutting attachment may spin during idle speed adjustments. Wear protective clothing and observe all safety instructions to prevent serious personal injury.

Checking the fuel, cleaning the air filter, and adjusting the idle speed should solve most engine problems. If not and all of the following are true:

the engine will not idle

the engine hesitates or stalls on acceleration

there is a loss of engine power

Have the carburetor adjusted by an authorized service dealer.

ROCKER ARM CLEARANCE

This requires disassembly of the engine. If you feel unsure or unqualified to perform this, take the unit to an authorized service center.

NOTE: Inspect the valve to rocker arm clearance with a feeler gauge after the first 10 hours of operation and every 25 hours of operation.

The engine must be cold when checking or adjusting the valve clearance.

This task should be performed inside, in a clean, dust free area.

1.Remove the six (6) screws on the back of the engine cover with a Flat-head or T-25 Torx screwdriver (Fig. 51).

2.Disconnect the spark plug wire.

3.Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8 in. socket counterclockwise.
