NOTE: One gallon (3.8 liters) of unleaded gasoline

mixed with one 3.2 oz. (95 ml) bottle of 2-cycle oil makes a 40:1 fuel/oil ratio.

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.

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

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

NOTE: Dispose of the old fuel/oil mix in accordance

to Federal, State and Local regulations.

Oil and Fuel Mixing Instructions

Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.

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. It forms acids when stored. When using alcohol-blended fuel, use fresh fuel (less than 60 days old).

Using Blended Fuels

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

• Always use the fresh fuel mix explained in your operator's manual

• Always agitate the fuel mix before fueling the unit

• Drain the tank and run the engine dry before storing the unit

Using Fuel Additives

The bottle of 2-cycle oil that came with your unit contains a fuel additive which will help inhibit corrosion and minimize the formation of gum deposits. It is recommended that you use our 2-cycle oil with this unit.

If unavailable, use a good 2-cycle oil designed for air-cooled engines along with a fuel additive, such as STA-BIL®Gas Stabilizer or an equivalent. 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 fuel tank.

For proper engine operation and maximum reliability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.

Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in a separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank. See the table below for specific gas and oil mixing ratios.

Holding the Trimmer

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. 5-7). Check for the following:

• The operator is wearing eye protection and proper clothing

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

• The operator’s left arm is straight, the left hand holding the D-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 ove

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. 5-8) while operating the trimmer at high speed.

NOTE: Always keep the trimming line fully

extended. Line release becomes more difficult as cutting line becomes shorter.

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

For best results, tap the bump knob on bare ground or hard soil. If you attempt a line release in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter.

NOTE: Do not rest the Bump Head on the ground

while the unit is running.

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.

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

• 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.

• Cut from right to left whenever possible. Cutting to

the left 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 forwardbackward 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:

• Following the trimming techniques

• What vegetation is being cut

• 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 T rimming

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. 5-9).

NOTE: Maintenance, replacement or repair of the

emission control devices and system may be performed by any non-road engine repair establishment, individual or authorized service dealer.

In order to assure peak performance of your engine, inspection of the engine exhaust port may be necessary after 50 hours of operation. If you notice lost RPM, poor performance or general lack of acceleration, this service may be required. If you feel your engine is in need of this inspection, refer service to any non-road engine repair establishment, individual or authorized service dealer for repair. DO NOT attempt to perform this process yourself as engine damage may result from contaminants involved in the cleaning process for the port.

Air Filter Maintenance

Cleaning the Air Filter

To avoid serious personal injury, always turn your trimmer off and allow it to cool before you clean or service it.

Clean and re-oil the air filter every 10 hours of operation. It is an important item to maintain. Failure to maintain the air filter will VOID the warranty.

1. Remove the carburetor/air filter cover by pushing on

the tab on top of the cover (Fig. 6-10).

2. Remove the air filter (Fig. 6-11).

3. Wash the filter in detergent and water. Rinse the

filter thoroughly and allow it to dry.

4. Apply enough clean SAE 30 motor oil to lightly coat

the filter (Fig. 6-12).

5. Squeeze the filter to spread and remove excess oil

(Fig. 6-12).

6. Reinstall the filter (Fig. 6-11) and air filter cover

(Fig. 6-10).

NOTE: If the unit is operated without the air filter, you

will VOID the warranty.

Spark Arrestor Maintenance

To avoid serious personal injury, always turn your trimmer off and allow it to cool before you clean or service it.

1. Turn the powerhead so the back of the engine is

facing forward. In this position, the starter rope is to the left (Fig. 6-13).

2. Use a needle-nose pliers to grasp the collar of the spark arrestor and pull it out of the muffler (Fig. 6-14).

NOTE: Use only a needle-nose pliers. Other pliers or

tools may damage the spark arrestor.

3. Clean the spark arrestor with a wire brush. Replace it if it is damaged or if you are unable to clean it thoroughly.

4. Reinstall spark arrestor. Use the needle-nose pliers to gently push the spark arrestor back into the muffler until it snaps into place.

Carburetor Adjustment

The idle speed of the engine is adjustable by the screw next to the air filter cover (Fig 6-15).

NOTE: Careless adjustments can seriously damage

your unit. An authorized service dealer should make carburetor adjustments.

Fig. 6-14

Check Fuel Mixture

Old and/or improperly mixed fuel is usually the reason for improper unit performance. Drain and refill the tank with fresh, properly mixed 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 and change the air/fuel mixture. 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

The cutting attachment may be spinning during idle speed adjustment. Wear protective clothing and observe all safety instructions to prevent serious personal injury.

If, after checking the fuel mixture 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.

2. Release the throttle trigger and let the engine idle. If the engine stops, insert a small phillips or flat blade screwdriver into the screw next to the air filter cover (Fig. 6-15). 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.

Checking the fuel mixture, cleaning the air filter, and adjusting the idle speed screw should solve most engine problems. If not and all 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.

Cleaning

To avoid serious personal injury, always turn your trimmer off and allow it to cool before you clean or do any maintenance on it.

Use a small brush to clean off the outside of the unit. Do not use strong detergents. Household cleaners that contain aromatic oils such as pine and lemon, and solvents such as kerosene, can damage plastic housing or handle. Wipe off any moisture with a soft cloth.

Storage

• Never store the unit with fuel in the tank where fumes

may reach an open flame or spark.

• Allow the engine to cool before storing.

• Store the unit locked up to prevent unauthorized use or

damage.

• Store the unit in a dry, well-ventilated area.

• Store the unit out of the reach of children.

Long T erm Storage

If the unit will be stored for an extended time, use the following storage procedure:

1. Drain all fuel from the fuel tank into a container with the same 2-cycle fuel mixture. Do not use fuel that has been stored for more than 60 days. Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations.

2. Start the engine and allow it to run until it stalls. This ensures that all fuel has been drained from the carburetor.

3. Allow the engine to cool. Remove the spark plug and put 1 oz. (30 ml) of any high quality motor oil or 2-cycle oil into the cylinder. Pull the starter rope slowly to distribute the oil. Reinstall the spark plug.

NOTE: Remove the spark plug and drain all of the oil

from the cylinder before attempting to start the trimmer after storage.

4. Thoroughly clean the unit and inspect it for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. The unit is ready for storage.

Transporting

• Allow the engine to cool before transporting.

• Drain fuel from unit.

• Tighten fuel cap before transporting.

• Secure the unit while transporting.

Replacing the Spark Plug

Use a Champion RCJ6Y spark plug (or equivalent). The correct air gap is 0.025 inch (0.655 mm). Remove the plug after every 25 hours of operation and check its condition.

1. Stop the engine and allow it to cool. Grasp the plug wire firmly and pull the cap from the spark plug.

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

3. Replace cracked, fouled or dirty spark plug. Set the air gap at 0.025 inch (0.655 mm) using a feeler gauge (Fig. 6-16).

Do not sand blast, scrape, or clean electrodes. Grit in the engine could damage the cylinder.

4. Install a correctly-gapped spark plug in the cylinder head. Tighten by turning the 5/8 inch socket clockwise until snug.

If using a torque wrench torque to:

110-120 in.•lb. (12.3-13.5 N•m). Do not over tighten.
