OIL AND FUEL INFORMATION

RECOMMENDED OIL TYPE

Using the proper type and weight of oil in the crankcase is extremely important. Check the oil before each use and change the oil regularly. Failure to use the correct oil, or using dirty oil, can cause premature engine wear and failure.

Use a high-quality SAE 30 weight oil of API (American Petroleum Institute) service class SF, SG, SH.

ADDING OIL TO CRANKCASE: INITIAL USE NOTE: This unit is shipped

without oil. In order to avoid damage to the unit, put oil in the crankcase before you

attempt to start the unit. Your unit is supplied with one 3.04 fluid oz. (90 ml.) bottle of SAE 30 SF, SG, SH oil (Fig. 15).

NOTE: Save the bottle of oil. It can

be used to measure the correct amount during future oil changes. See Changing the Oil.

1. Unscrew the top of the bottle of oil and remove the paper

seal covering the opening. Replace the top. Next, cut the tip off the funnel spout (Fig. 15).

2. Tip unit so that the back of the engine is facing up in a

vertical position.

3. Remove the oil fill plug from the crankcase (Fig. 16).

4. P

our the entire bottle of oil

into the oil fill hole (Fig. 17).

NOTE: Never add oil to the

fuel or fuel tank.

5. Wipe up any oil that may

have spilled and reinstall the oil fill plug.

Check oil before each use and change as needed. Refer to Checking the Oil Level.

WARNING: OVERFILLING OIL CRANKCASE MAY CAUSE SERIOUS PERSONAL INJURY. Check and maintain the proper oil level in the crank case; it is important and cannot be overemphasized. Check the oil before each use and change it as needed.

See Changing the Oil.

RECOMMENDED FUEL TYPE

Old fuel is the primary reason for improper unit performance. Be sure to use fresh, clean, unleaded gasoline.

NOTE: This is a four cycle engine. In order to avoid damage to

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

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

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.

O-Ring

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.

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

OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

Before operating the unit, stand in the operating position (Fig. 25). 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

• 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

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. 26) 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

• 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).

USING THE CUTTING BLADE

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.

• 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.

• 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

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.

WARNING: Always wear eye, hearing, foot and

body protection to reduce the risk of injury when operating this unit.

Fig. 25

Fig. 27

Fig. 26

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.

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

• 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 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.

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.

OPERATING INSTRUCTIONS

WARNING: To prevent serious injury, never

perform maintenance or repairs with unit running. Always service and repair a cool unit. Disconnect the spark plug wire to ensure that the unit cannot start.

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.

4. Remove the engine cover (Fig. 51).

6. Pull the starter rope slowly to bring the piston to the top of its travel, (known as top dead center). Check that:

• The piston is at the top of its travel while looking in the spark plug hole (Fig. 53)

• Both rocker arms move freely, and both valves are closed

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

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.

MAINTENANCE AND REPAIR INSTRUCTIONS

WARNING: The cutting attachment may spin during

idle speed adjustments. Wear protective clothing and observe all safety instructions to prevent serious personal injury.
